Classification of high temperature and low temperature conveyor belts

In industrial applications, conveyor belts can be divided into high-temperature conveyor belts and low-temperature conveyor belts according to the temperature range they can withstand. The following is a detailed introduction to these two types of conveyor belts:

High temperature conveyor belt

High temperature conveyor belts are mainly used to transport materials in high temperature environments and can withstand high temperatures without performance degradation or damage. Common high temperature conveyor belts include:

1.Heat-resistant and high-temperature conveyor belts: This type of conveyor belt is usually made of special materials, such as PVC, PU, ​​silicone, etc., and has excellent high-temperature resistance. They can maintain stable physical and chemical properties in high-temperature environments to ensure the smooth transportation of materials. PVC and PU conveyor belts are generally used at temperatures between -10°C and +80°C, but specific high-temperature versions can withstand higher temperatures.

2. Felt heat-resistant and high-temperature conveyor belts: This conveyor belt is covered with wool on the surface, which is oil-resistant and breathable, and is mostly used for the protection and transportation of glass. Its bottom layer is made of wear-resistant material, which can increase tension and can be customized according to requirements. Felt conveyor belts can withstand temperatures up to about 480 degrees, and are suitable for working environments that require scratch-free and high-temperature resistance, such as automobiles, precision ceramics, electronics, and circuit boards.

3. Teflon heat-resistant and high-temperature conveyor belts: This conveyor belt is suitable for environments with low temperatures of -70°C to high temperatures of 260°C, and has weather resistance and anti-aging properties. After continuous use at 250℃ for 200 days, its strength and weight will not decrease; after being placed at 350℃ for 120 hours, the weight only decreases by about 0.6%.

4. Silicone heat-resistant and high-temperature conveyor belt: This conveyor belt is suitable for various high-temperature conveying occasions, as well as conveyors that require the conveyor belt surface to be non-sticky, such as conveying sugar foods. It can withstand temperatures up to 220 degrees and is often used for conveying tasks in airports, post offices, warehouses and other departments.

Low temperature conveyor belt

Low-temperature conveyor belts are mainly used to transport materials in low-temperature environments and can withstand lower temperatures without affecting performance. Common low-temperature conveyor belts include:

1.Cold-resistant conveyor belt (low-temperature resistant conveyor belt):

This type of conveyor belt uses cotton canvas, nylon canvas or polyester canvas as the skeleton material, and the surface covering rubber uses butadiene rubber with excellent cold resistance and natural rubber with outstanding weather resistance. They have excellent cold resistance, high elasticity, impact resistance, wear resistance and other characteristics, and can be used for a long time in an environment of minus 40℃. It is mainly used in northern mines, plateau mines, coal transportation and other environments. According to the different covering rubber performance and cold resistance, cold-resistant conveyor belts can be further classified.

。According to the covering rubber performance: scratch-resistant type (H), wear-resistant type (D), general type (L).

。According to the cold resistance performance: C1 grade (the operating environment temperature is -45℃ to +50℃ or -50℃ to -45℃) and C2 grade (the operating environment temperature is -60℃ to +50℃ or -60℃ to -50℃).

2.Low-temperature resistant light conveyor belt:

This conveyor belt is mainly used in food processing, meat freezing, chilled seafood, quick-frozen food and other environments. The conveyor belts used in these working conditions must meet food grade requirements. For example, Volta has developed a low-temperature resistant conveyor belt of -45 to 55 degrees, which can be used in most low-temperature environments and has passed the US FDA, USDA and EU certification, meeting food and drug grade requirements.

High-temperature conveyor belts and low-temperature conveyor belts differ in material, structure and performance to adapt to different working environments and material conveying requirements. When selecting a conveyor belt, it is necessary to comprehensively consider factors such as specific working temperature, material characteristics, and conveying distance.
