How many kinds of polyester conveyor belt are on the market?

  Polyester conveyor belt is also called as EP conveyor belt, anti-abrasion conveyor belt, automatic conveyor belt and concrete conveyor belt. It has lots of advantages such as high modulus of belt, low extension, good heat resistance and impact resistance, which is adjustable to conveying something of medium and long distance, high cut and high speed transportation. Polyester conveyor belt is used to transporting materials of coal, mining, port, metallurgy, electric power and chemical industries.

  Features

1 High strength, thin body and light weight

2. EP rubber impregnated canvas is used as the skeleton material

3. The belt is soft, with good grooving and elasticity

4. Shock resistance, wear resistance and corrosion resistance

5. Adapt to heavy load, fast speed and medium and long distance material transportation

6. Smooth operation without deviation

  The paper introduces the characteristics of several kinds of ordinary adhesive materials used in conveyor belt. Generally, the adhesive materials used for various parts of the conveyor belt include cover glue, buffer glue, cloth layer rubbing glue and cloth layer sticking glue. The first kind, the rubber conveyor belt is influenced by the impact of materials, wear and microbial erosion, as well as various aging effects.Therefore, it is required that the covering adhesive have good tensile strength (18Mpa or greater) and abrasion resistance (abrasion consumption: 0.8cm3/1.61km), anti-aging and bio-erosion.In addition, it is also required to have good viscosity and other technical properties. The formula design points are as follows, raw rubber is mainly made of natural rubber or proper amount of styrene butadiene rubber. Vulcanization system adopts traditional system of sulfur and accelerator.In the natural rubber formula, the amount of sulfur is about 2.5 parts of mass. In the formula of styrene butadiene rubber, the amount of sulfur is 1.5~2.0 mass fraction.The accelerators are usually M and DM, and the accelerators CZ and NOBS are suitable for the adhesive containing styrene rubber.The reinforcing agent can choose high wear-resistant carbon black, medium and ultra-wear-resistant carbon black, etc., the dosage is 40-50 quality parts.The types of softeners commonly used are machine oil, heavy oil, pine tar, coumarone resin and petroleum resin.

  The second kind: the buffer belt of the buffer rubber conveyor is between the covering glue and the core layer, which can increase the adhesive force of the two, absorb and disperse the impact force of the conveying materials, thus acting as a buffer.It is required that the adhesive has good adhesion (the adhesion between adhesive and cloth is greater than 3.15n /mm), high elasticity, low heat generation, good heat dissipation and good process performance.Raw rubber is generally made of natural rubber and butyl rubber, with a gum content of 50%~55%The vulcanization system should use low sulfur to improve adhesion between adhesive layer and cloth layer.M, DM and TMTD were used as accelerators.Carbon black is commonly used with high abrasion resistance and half-complement strong carbon black.The softeners are of good viscosity, such as pine tar and solid coumarone.
