8 Questions to Ask When Choosing a Conveyor Belt

For more information, please visit Huaqiang.

When choosing a belt conveyor system, one of the most important decisions you'll have to make is which belt it should be equipped with. In most cases it's the only part of the conveyor that's actually in contact with your parts, product or packaging.

Here are eight important questions to ask when choosing a belt:

What is the coefficient of friction? ' Belt surfaces range from an extremely low coefficient of friction to a high coefficient of friction. Low friction belts are ideal for accumulation applications or side-entering or -exiting applications where product must slide while the belt continues to move. High friction belts are often found in incline applications up to 15° to ensure positive product movement simply through friction between the product and the belt.

What are the maximum and minimum temperatures? ' There are two temperatures you should be concerned with: ambient operating temperature and temporary part temperature. Each is important for the long-term function of the belt. Ambient temperatures that are too cold can lead to brittleness and cracking of the belt; temperatures that are too high could lead to belt stretch or delamination at the splice. Short-term part temperature specifications ensure hot parts don't damage the surface of the belt when they're placed or dropped onto the conveyor.

What color is the belt? ' Color is most important in inspection applications, whether it's automated with cameras or a visual inspection by an operator. Proper color contrast with the product can be vital for spotting defects or impurities. Blue is very common in food applications since it's a color that rarely appears naturally in foods, making it easy to spot residue after cleaning.

Is the belt cut resistant? ' If your product has sharp edges, a cut resistant belt may be necessary to avoid cutting the surface of the belt. These belts typically include a hardened urethane or PVC top surface.

Should I use a sealed edge belt? ' To reduce particulates in cleanroom environments, a sealed edge belt is typically recommended. These encapsulate the cut edges of the belt to seal in the fibers of the carcass. Without a sealed edge, those fibers may be released as the belt flexes around the pulley.

Does the belt have release properties? ' In some applications, product may tend to stick to the belt, whether it's a sticky confectionery product or glue from a packaging process. A silicone belt helps to ensure the product is released cleanly.

Do I need cleats? ' Cleated belts are common for applications where parts need to be pushed up an incline or restricted from sliding or rolling down a decline. They're also used to maintain product spacing, especially in applications where parts are fed manually by an operator. Cleats are placed at custom intervals based on the customer's specifications and are available in a variety of heights for different products and applications.

What's in stock? ' All these considerations mean nothing if finding the perfect belt would push the lead time past the date you need the conveyor. With hundreds of potential belt types, it would be impractical for conveyor manufacturers to stock every type. Most manufacturers stock a limited number (at QC Conveyors we stock seven types, which cover about 95% of our conveyor orders) and rely on the belt manufacturers to supply others as needed. This can double or triple the lead time for the conveyor, so it's important to know which belts your conveyor manufacturer stocks, especially if you need a conveyor quickly. You may be able to compromise on one of the other requirements to help meet your lead time requirement.

Manufacturers produce fiberglass mesh by knitting fiberglass yarns into fiberglass woven cloth with square-shaped openings, then covering it with alkaline resilient latex to provide flexibility and nice alkali resistance and stretching and tearing resistance qualities. People use fiberglass mesh extensively in thermal insulation, plastering, and to make the exterior and interior ceilings and walls of buildings fireproof and waterproof after purchasing it from a China fiberglass mesh supplier. Builders use fiberglass meshes to ensure that interior walls do not suffer from cracks. One of the essential factors which people should consider while buying fiberglass mesh is alkali resistance.

The profile of alkali-resistant fiberglass mesh

Manufacturers make alkali-resilient fiberglass mesh by weaving fiberglass roving as its foundation mesh, and then they cover that mesh with alkali resilient macromolecule latex. After getting surface treatment, this alkali-resilient fiberglass mesh has great alkali resistance, resistance to aging, softness, flexibility, water resilience, and high strength. Builders use alkali-resistant fiberglass mesh to make roofs waterproof and to carry out wall reinforcement and exterior wall insulation. Suppliers offer alkali-resistant fiberglass mesh in different colors(green, yellow and white) and in different weights(forty-five grams, eighty grams, one hundred and twenty grams, one hundred and thirty grams, one hundred and forty-five grams, one hundred and sixty grams, and three hundred grams), supporting polyvinyl chloride insulation guard for choice. Manufacturers can custom unique design specifications of the fiberglass mesh to meet the requirements of the fiberglass mesh's users.

Alkali-resistant fiberglass mesh has essential features: high tensile strength, excellent corrosion resistance, and good cohesion. People can use this type of fiberglass mesh in wall heat reservation systems to make them waterproof. The Alkali-resistant fiberglass mesh is an excellent material to reinforce cement concrete effectively. This is because of its strong fracture strength and elastic modulus. This mesh would not deteriorate due to ultraviolet radiation. And only utilizing an incredibly tiny amount of mortar coverage would be able to attain the wanted improvement. To fully use fiberglass mesh, it is essential to utilize fiberglass tape.

Usages of Alkali-resistant fiberglass meshes

Use for external wall insulation

Fiberglass alkali resilient mesh is an essential structural substance in a whole exterior insulation system. Alkali-resistant fiberglass mesh has characteristics of good adhesion and high strength. Builders can efficiently combine alkali-resistant fiberglass with an insulation board polystyrene board to ensure that the alkaline substances used in making the construction materials do not get corroded. It could efficiently prevent the cracking of the wall and improve resistance to pressure as a tremendous reinforcing substance.

Roofing applications

As water-resistant medium(asphalt) has no power applied in waterproofing and roofing systems under the extrinsic forces of sun, wind, and changes in seasonal temperature, it is likely to crack, leak, and will not attain the impact of water resistance. Adding a water resistance membrane comprising composite carpet or fiberglass mesh could improve its tensile strength and wind resistance. In this manner it could tolerate different stress changes without breaking to attain a long-term impact of waterproofing and circumvent the inconvenience and roof leakage discomfort caused by people.

Storage of Alkali resistant fiberglass mesh

People should store alkali-resistant fiberglass mesh in a preferably dry atmosphere at a temperature of fifteen to thirty five degrees Celsius and maintain a relative humidity level between thirty-five to sixty-five percent inside the original packing. If the item is stored in a cold environment with a low temperature of less than fifteen degrees, its better to store it in an atmosphere of twenty-three degrees for one day to prevent brittle or condensation before utilizing it at ambient temperature.

Why should people install a fiberglass mesh for a render system?

Fiberglass mesh is an integral part of a render system as it helps toughen and offer greater flexibility to thin cover render systems. It assures that the render survives for years without suffering from cracking or premature tear and wear. The fiberglass mesh which people install in a render system is composed of complicatedly woven fiberglass yarn. People commonly utilize this kind of fiberglass mesh in wall reinforcement rendering and plastering, external wall insulation and roof waterproofing.

Various fiberglass mesh weights are offered depending on the use- the bulkier the mesh, the greater affect resistance would be inside the render system. People should install an alkali resistant fiberglass mesh in a render system because it plays a significant role in preventing it from damaging whenever exposed to chemicals in the rest of adhesive compounds and mortars. Manufacturers have designed the alkali-resisting fiberglass mesh to avert wall breaking through reinforcement for external and internal tiling and to carry out rendering and plastering applications. Apart from that, it provides great stability and highly tear resistance. The one hundred and sixty g/m2 fiberglass reinforcement mesh is covered with acrylic acid copolymer fluid, which tells us that it is also age and water resistant.
