PVC anti-fire and anti static electricity conveyor belt often called PSAF. it select high-intensity nylon filament and yarn weave.as a whole core, and then use the PVC impregnated. Their technologies and key equipment are introduced from the United Kingdom, Specialization(Fenner) Corporation. PSAF have advantage of anti-static electricity, high-intensity, with light body, long life characteristics in the modern world.

It is the best security for the coal mine belt.

● Width Specifications(mm): 400 500 650 800 1000 1200 1400 1600 1800 2000

● Intensity specifications(N/mm):

● The belt has good flame resistant and anti-static properties. It can fully satisfy the requirements of MT-914 and is especially suitable for material conveying at inflammable conditions of underground coal mines.

● The solid woven fabric uses high tensile strength and low elongation polyester long filament as warp fibre, for weft fibre, it uses high tensile and medium modulus nylon filament. The fabric is high in strength, low in elongation,light in carcass,free of separation of plies, shock resistant, anti-tear and good in troughability.

● Non pressed PVC type is suitable for applications in dry conditions at a slope angle of no greater than 16 degrees.

● Cover rubber’s characteristics:

Shaoer A hardness rubber surface 604±5°，plastic suface 75±5°

Abrasion is no less than 0.7Gm³/1.61Km

● Security functions:

(1) The arithmetic average time of six full-thickness samples on a special forms and non-flame burning should not passed 3 seconds,the single value can not be larger than 10 seconds.the arithmetic average time of 18 samples whose cover rubber had been stripped off on a special forms and non-flame burning should not passed 5 seconds,the single value can not be larger than 15 seconds.

(2) The value of the surface resistance test pieces.Surface resistance is not more than 3x10".

(3) Roller cylinders friction tests roller cylinders friction tests roller cylinders surface temperature should not exceed 325'C,any of its parts should not had a flame burning and no combustion phenomena.

(4) Tunnel propane combustion tests.
