How to Clean Different Outdoor Furniture Fabric

Posted on by

Outdoor furniture is designed with durability and longevity in mind, as it has to battle the elements of a patio, backyard, or deck. Designers have created unique fabric blends to resist fading, tearing and to be easy to clean after long periods of storage. There are several types of materials commonly used in outdoor furniture, and each requires a different level of care and cleaning routine.

 

Solution-Dyed Acrylics

 

Commonly used for softer, more pliant pieces of furniture, solution-dyed acrylics are commonly used for outdoor pillows, umbrellas, and awnings. To create this type of fabric, the acrylic is formed in to colored fibers prior to becoming thread and dyed prior to being woven into cloth. This chemical treatment makes the material water-resistant and provides a better colorfast, which means the fabric is far less likely to bleed color when wet. According to a home-guide on SFGate, to properly clean this soft, breathable material, use a mild, soapy solution in warm water. Easily wipe away any dirt or mildew with a soft sponge or cloth.

 

Acrylic-Coated Polyesters

 

Polyester is a durable, man-made material which is commonly used in protecting outdoor furniture, especially due to the availability of many color choices. Unlike the solution-dyed acrylic fabric, this type of fabric is woven prior to being dipped into a colorful acrylic coating. This type of material is also available as a polyester-cotton blend, and most commonly used in protective covers for automobiles and watercraft. To clean this material, shake or vacuum loose dirt or debris from the fabric before using a mild soap with lukewarm water to wash and rinse clean. The fabric should be allowed to air dry and properly breathe in order to prevent growth of mold or mildew.

 

Vinyl-Coated Synthetic Fibers

 

Also known as PVC mesh, this type of fabric is most commonly used in outdoor hammocks and sling-style chairs due to its strength and durability. PVC mesh is created from polyester or acrylic yarns which have been coated in vinyl for a strong, non-stretching material that is intended to support the weight of an individual. Vinyl-coated synthetic fibers are colorfast and easily cleaned with a cloth, lukewarm water, and a mild powdered soap solution. Avoid acid-based or vinegar-containing cleaning solutions, as these may damage the mesh. Never use an iron or heat exceeding 150 degrees as this may cause melting or warping of the material. Due to the combination of durable, water-resistant fabrics, PVC mesh is also mildew-resistant.

 

Synthetic Fabric

 

Other types of pliable, synthetic materials used in outdoor furniture include those designed to protect from fading and sun damage. Furniture covers and umbrellas take the brunt of the elemental beating, and have been designed to stand up to the harsher conditions which affect an outdoor space. According to Terra Patio, who specialize in outdoor furniture, to properly clean these types of fabrics, immediately brush off accumulated dirt and spot-clean spills quickly to avoid staining. Avoid cleaning products which contain bleach, as they may discolor the fabric, and do not use detergents. Mild dish soap and lukewarm water should suffice in caring for the area. Avoid using an iron or steamer on the synthetic fabric as it may warp or melt. Air dry for best results.

 

Olefin

 

Olefin is a man-made material related to plastic which is created by heating polyethylene (or other petroleum-based compounds) and pressed in to a spinneret to create long fibers. Olefin is manufactured in a similar style to other man-made fabrics such as nylon or polyester, but has a much smoother texture. Olefin is used in furniture such as lawn chairs and outside carpeting due to its quick-drying and weather-resistant properties. It is also stain and mildew-resistant, making it a great fabric for the outdoors. To clean Olefin, wipe off or vacuum dirt particles before using a mix of bleach, dish detergent, and warm water. Saturate the fabric with the solution and rinse well.

 

Properly caring for outdoor furniture increases the longevity of the pieces, protecting against mold, dry rot, and damage due to adverse weather conditions. Although the fabric used in the manufacture of outdoor furniture is more durable than those intended for exclusive indoor use, homeowners should properly clean and store their patio furniture when not being used for an extended period of time.

What is a Pressure Control Valve and Why Do You Need It?

Posted on by

Pressure control valves are found in virtually every hydraulic system, and they assist in a variety of functions, from keeping system pressures safely below a desired upper limit to maintaining a set pressure in part of a circuit.

 

Every pressure control valve switches (or controls) at a predetermined pressure setting. The switching pressure is generally a variable setting on the valve itself. A change in position of the pressure control valve (i.e. open or closed) occurs either gradually (by control) or suddenly (by switch). Pressure shut-off valves and pressure sequence valves are hydraulic valves with a fixed throttle whereas relief and reducing valves are hydraulic valves with a variable throttle.

 

Pressure valves are hydraulic valves that gradually (control) or suddenly (switch) change in position.

 

The most common types of pressure control valves are the pressure relief valve and the pressure reducing valve. Pressure relief valves control the system pressure by relieving part, or all, of the flow to tank. Pressure reducing valves reduce the pressure supplied to a sub-system of a hydraulic system. Sequence valves are used to direct the flow to a secondary circuit. Unloading valves are used to direct flow to tank at pre-set system pressure.

 

Type of Pressure Control Valves

 

  • Pressure valves, relief function
  • Pressure valves, reducing function
  • Pressure valves, fixed throttle

 

A hydraulic system can only function – as per requirements – by using valves. Thus, you should always look for the correct type of hydraulic valve to serve your intended purpose. You can try to browse the website of ASHUN, the professional hydraulic valves manufacturer in the industry, to get more information about pressure control valves.

Difference between Manual Thermostats and Electrical Thermostats

Posted on by

A thermostat is a temperature–sensitive device that turns HVAC systems on and off when the temperature of an environment reaches a preset level. Essentially, it turns on the air conditioning when it gets too warm, or the heating when it gets too chilly. Thermostats control the workings of comfort systems by directing energy to the appropriate system when needed. When selecting a thermostat, property owners can either go for simple manual thermostats or sophisticated electronic thermostats that provide improved functionality and highly efficient operations. Thanks to the easy to understand packaging and universal compatibility, choosing a thermostat is easy.

 

Systems that Use a Thermostat

Single–stage heating systems have one electrical or gas heating device, which may consist of a heater or an AC device as well. Most units that use natural gas provide single–stage heating. Usually, a single–stage thermostat should have room for three wires if the system handles heating only. However, if the system handles heating and cooling, the thermostat will have to accommodate five wires or less.

 

Multi–stage systems have a standard electrical or gas heating device as well as an emergency and/or auxiliary heating device. The emergency or auxiliary heating kicks in when temperatures drop faster than the standard heater can handle, or if the standard heater fails. Line voltage systems, on the other hand, use direct current. Homeowners should choose line voltage thermostats that can handle additional conducted power.

 

Difference between Manual and Programmable Electrical Thermostats

 

Electromechanical or annual thermostats are the traditional mercury units that have internal coils to contract and expand in response to changes in temperature. They are becoming obsolete because of two main reasons:

 

  • Products containing mercury are banned or restricted in most states
  • Programmable thermostats are more accurate and sensitive to temperature changes

 

However, manual thermostats are still popular due to their ease of use, low cost, and the familiarity of their controls.

 

Digital manual thermostats use an electronic sensor to register temperature changes in an environment and then compare those changes to the preset settings. If there is a difference, the thermostat sends a warning to the cooling or heating system that immediate action is required. However, users still have to physically adjust the settings to their preferred level.

 

Programmable electrical thermostats are an upgrade from the manual thermostats. In addition to saving energy costs, they allow homeowners to program their preferred temperature settings into the unit’s memory, along with the time of day they would like the changes to occur.

 

For most homes, a pre–programmed electrical thermostat does not need any adjustment. Homeowners simply need to install it and they are ready. When determining the right thermostat, homeowners should consider the flexibility and functionality they need from day to day.

 

Alpha Brass electrical thermostats are manufactured and calibrated with precision to provide accurate temperature points. These thermostats are snap-acting and the temperature is controlled by signal interrupting the gas flow to the burner.

How to Use Metal Eyelets?

Posted on by

Sometimes you see projects and they just don’t look finished. They are probably fine the way they are, but a little dressing up never hurt anything, right? One of the ways you can dress up plain punched holes is with eyelets. They aren’t hard to use when you know how, so here are a few tips to get you started!

 

There are several sizes of scrapbooking eyelets, such as 1/8″ and 3/16″. This size refers to the hole in the center of the eyelet, not the outside diameter of the design. They come in all shapes and sizes, similar to scrapbooking brads.

 

One question I get asked a lot is, “are these for use on cloth or clothing?” Certainly we all see metal eyelets all the time on curtains, hats, belts, and on shoes & hoodies where the strings go through. Generally, these are a sturdier type of eyelet than scrapbooking eyelets and they have to be attached with a special setter that can go through thick materials. So while you might be able to use scrapbooking eyelets on cloth, they probably won’t stand up well to the harsh environment of wear and washing for very long.

 

Scrapbooking eyelets are usually a weaker metal than clothing eyelets and can easily be attached with a simple metal setter and a craft hammer. There are even eyelets that can be set with a ball point pen tip. They are called Quicklets and are made by Eyelet Outlet. The metal is very soft and is scored so that the back flattens easily when pushed on firmly with a pen tip.

 

Depending on your budget, there are several types of eyelet setters available on the market. There are silent setters which are a spring-loaded type of setter, the crop-a-dile, a squeeze type of tool, but most common and economical is the eyelet setter tool. An eyelet setter is a metal took about 5″ long with a special tip that fits into the hole on the back of the eyelet.

 

To set a metal eyelet, simply make a small hole in your paper and place the eyelet through the hole. Then turn the paper & eyelet over onto a firm surface. Place the tip of the setter into the hole, Give the top of it a firm whack or two with a craft hammer. That’s it! The back of the eyelet will splay out holding the eyelet in place. If you need a neat appearance on the backside of your project, consider buying finishing washers or rivets. They are placed on the back of the eyelet before setting it.

 

Metal eyelets are often used for lacing ribbons just like on clothing. They make a great embellishment for the top of a tag and also work well for joining several pieces of paper together. They’re a great staple for any paper crafter’s supply closet, so hope you give them a whirl today!

Overview and Advantages of the Hydraulic Radial Drill

Posted on by

Can you imagine the hassles of not being able to drill a hole through a work piece that is too large to fit in your drilling machine’s table? The limitations of your drilling machine may be inconvenient, but the radial arm drill press puts an end to this dilemma.

 

A hydraulic radial drill or radial arm press is a geared drill head that is mounted on an arm assembly that can be moved around to the extent of its arm reach. The most important components are the arm, column, and the drill head. The drill head of the radial drilling machine can be moved, adjusted in height, and rotated. Aside from its compact design, the radial drill press is capable of positioning its drill head to the work piece through this radial arm mechanism.

 

This is probably one of the reasons why more machinists prefer using this type of drilling machine. In fact, the radial drilling machine is considered the most versatile type of drill press. The tasks that a radial drilling machine can do include boring holes, countersinking, and grinding off small particles in masonry works.

 

Although some drill presses are floor mounted, the most common set-up of hydraulic radial drills are those that are mounted on work benches or tables. With this kind of set-up, it is easier to mount the drill and the work pieces. There is no need to reposition work pieces because the arm can extend as far as its length could allow. Moreover, it is easier to maneuver large work pieces with the radial arm drilling machine. Large work pieces can be mounted on the table by cranes as the arm can be swiveled out of the way.

 

Here are some of the major parts of the radial arm drilling machine:

 

Column – the part of the radial arm drill press which holds the radial arm which can be moved around according to its length.

 

Arm Raise – adjusts the vertical height of the radial arm along the column.

 

On/Off Button – the switch that activates and deactivates the drill press.

 

Arm Clamp – secures the column and the arm in place.

 

Table – is the area where the work pieces are fed and worked on.

 

Base – the radial arm drill press part that supports the column and the table.

 

Spindle – the rotated part of the drill press which holds the drill chuck used in holding the cutting tool.

 

Drill Head – the part of the drill press that penetrates through the material or work piece and drill through the specific hole size.

 

Radial Arm – holds and supports the drill head assembly and can be moved around on the extent of its length.

 

There are a number of advantages of using the radial arm drill press. One of these advantages is the amount of area that it can cover which is only dependent on the length of the arm. Another advantage is the considerable size of work that it can handle since the arm can actually swivel out of the working area allowing cranes and derricks to place work pieces on the table. Finally, less effort is required during the drilling process because the arm assembly seemingly is doing all that is needed for specific tasks to be completed.

Thread Milling VS. Tapping

Posted on by

There are some distinct differences between thread milling and tapping. This article explains the advantages and disadvantages of each so that you can make an educated decision about the strategy that will work best for your parts.

 

Tapping: Advantages and Disadvantages

The greatest advantage of tapping is speed. High-speed tapping centers set up with a rigid tap can thread holes in a fraction of the time it would take to thread mill the same holes. Additionally, tapping can thread deeper holes in harder materials such as steel.

 

A significant disadvantage of tapping is that a different size tap is required for each size hole that needs to be threaded. This can consume a large number of valuable, but limited positions in the tool magazine. Plus, having to switch tapping tools for all of the various size holes increases the cycle time.

 

Another disadvantage is that tapping does not allow for adjusting thread fit. Once the hole is tapped, the size and position of the thread is final. Also, rigid taps are used exclusively for interior threading of holes and cannot be used to mill threads onto the outside of a post or screw.

 

Finally, since the initial portion of a rigid tap is designed to plunge into material rather than making perfect threads, these tools are best for tapping through holes rather than blind tapping, which is threading holes that end within the material. In the case of blind tapping, the deepest threads in the hole are made with the part of the tool that is designed to plunge rather than thread. To complete these last areas as perfect threads, a secondary finishing tool is required and results in longer cycle times.

 

As general rule of thumb, it is best to employ tapping when you need to make a lot of holes with few variations in size.

 

Thread Milling: Advantages and Disadvantages

The primary advantage of thread milling is the ability to control the fit. A threaded hole is milled at a high RPM and the tool helixes into a previously-milled hole. So, the machine operator has the ability to adjust thread size using a strategy similar to using an end mill, rather than a drill bit to make a hole. This can be advantageous if there are tight tolerances on the thread sizes or if allowances need to be made for finishing such as painting.

 

Also, a single tool can be used in thread milling to make a wide range of hole sizes. This reduces both the cost of tooling and the amount of time associated with tool changes. Plus, a thread mill can create interior and exterior threads, right-hand and left-hand threads, as well as very large threaded holes (e.g. pipe threads). In the case of the latter, this eliminates the need to invest in a large rigid tap to thread big holes.

 

Furthermore, the thread mill gives the user the ability to design custom threads without having to invest in custom taps which can be very expensive and require long lead times. In the machining of very shallow blind threads in thin materials, the thread mill allows for maximum threads in a very short distance.

 

The one disadvantage of thread milling is you need to be equipped with a high-speed spindle in order to do it properly.

 

The Bottom Line

If you need more flexibility, have a range of thread sizes and types and require the ability to adjust thread fits, thread milling is the best choice. If speed is your requirement, then rigid tapping is what you need.

What is a Scroll Chuck?

Posted on by

A self-centering chuck, also known as a scroll chuck, uses dogs (usually called jaws), interconnected via a scroll gear (scroll plate), to hold onto a tool or workpiece. Because they most often have three jaws, the term three-jaw chuck without other qualification is understood by machinists to mean a self-centering three-jaw chuck. The term universal chuck also refers to this type. These chucks are best suited to grip circular or hexagonal cross-sections when very fast, reasonably accurate (±0.005 inch [0.125 mm] TIR) centering is desired.

 

Sometimes this type of scroll chuck has 4 or 6 jaws instead of 3. More jaws grip the workpiece more securely if it is truly cylindrical, and thin-walled work will deform less. Four jaws are also useful for square bar work.

 

There are also independent-jaw (non-self-centering) chucks with three jaws.

 

There are hybrid self-centering chucks that have adjustment screws that can be used to further improve the concentricity after the workpiece has been gripped by the scroll jaws. This feature is meant to combine the speed and ease of the scroll plate’s self-centering with the run-out eliminating controllability of an independent-jaw chuck. The most commonly used name for this type is a brand name, Set-Tru. To avoid undue genericization of that brand name, suggestions for a generic name have included “exact-adjust”.

 

Three-jaw chucks are often used on lathes and indexing heads.

What are Metal Bond Grinding Wheels and What Benefits Do They Offer?

Posted on by

Extensively used in manufacturing diamond grinding wheels, metal bonds are manufactured utilizing three different processes: cold press, semi hot press and hot press modes.

Metal Bond Grinding Wheel
Cold press mode involves pressing the transition layer (no diamonds) and the working layer (with diamonds) of selected diamond portions to forms that on the body of the grinding wheel. These segments are then allowed to interconnect with the grinding wheel’s body via slots or teeth. Finally, cold press grinding wheels are placed into sintering furnaces where they are sintered without press.

 

Semi hot press mode improves on the cold press mode by complementing the sintering process. While grinding wheels are sintering in a furnace, applicable molds are applied and minimal to moderate pressure is added. However, any pressure applied is significantly lower than the amount of pressure applied in hot press mode.

 

Hot press mode directly sinters diamond particles in molds under preset pressure levels in sintering press machines. Diamond segments are then affixed on the grinding wheel using high frequency laser welding, high frequency welding or mosaic methods of mechanical welding.

 

Metal bond grinding wheels are produced when powdered metals or compounds containing cubic boron nitride or diamond are sintered on the wheel, resulting in exceptionally strong tools that maintain shape during rigorous use. In addition, metal bonding extends the life of grinding wheels by reducing the need for repeated dressings and continues being productive longer than market-brand super abrasives.

 

Benefits of Using Metal Bond Grinding Wheels

  • Because metal bond grinding wheels are sintered with cobalt, copper, mill, silver or stanum power, they work exceptionally well on a variety of surfaces (glass, refractories, ceramics, silicon, semi-conductors and quartz).
  • Whether used for tool cutting, glass grinding, ceramic grinding or form cutting, metal bond grinding wheels provide the longest, most superior quality of service before any type of maintenance is needed.
  • Metal bond offers the ability to perform outstanding interrupted cuts while retaining the tool’s original dimensions even during the most energetic grinding actions, including centerless, cylindrical, creep feed, deburring and cutoff applications.
  • Although resin bonds are more commonly used than vitrified or electroplated bonds, these bonds do not offer the hardness or wheel retention properties exhibited by metal bond grinding wheel.

 

As one of the most frequently seen machines in manufacturing plants requiring grinding applications, centerless grinders especially benefit from metal bond grinding wheels because of the slow, precise pace of material removal method demanded of these machines. Additionally, super abrasive centerless grinders necessitate powerful wheels such as metal bond grinding wheels that can effectively make predetermined alterations to products while reducing quality control issues that may arise if lesser quality wheels are used.

Something You Need to Know about Height of Volleyball Nets

Posted on by

The height of volleyball nets varies depending on the age group that is playing Volleyball. Logically, the net height is considerably lower for the younger players and it gets taller as the age group grows. Also, the net height for women is slightly lower than that for men’s volleyball, because females are typically smaller in height. The net is positioned at a height regardless of your age that requires a reasonable jump to get above it (unless you are unusually tall). For a tall Volleyball player, usually they can just reach the top of the net without jumping, but you wouldn’t be able to block or hit the ball over straight down without jumping.

 

What this means is that you need to learn to jump as high as possible. In fact, the taller that you can reach the more chance you have of getting the ball down on the opponent court. Some of the tall players in volleyball are able to jump up a meter in the air, meaning that their total reach is often near 3 and a half meters! The full net height for males is 2.43 meters, and for females it is 2.24 meters. The net height is adjusted by loosening the net with the winch, undoing the pin that goes through the net pole, sliding the net up and then fitting the pin in again. From there, you simply wind the net back up so it is taught.

 

You might think that just because you aren’t tall that you have no chance of being a good spiker. In experience, those that are smaller have bigger jumping abilities, meaning that they have about the same height jump as someone who is tall. Of course, being tall has its advantages for blocking and spiking. You can always increase your vertical jump, but you aren’t always able to grow more!
