Polyester conveyor belt, also known as EP conveyor belt,
wear-resistant conveyor belt, automatic conveyor belt, cement
conveyor belt, has high body modulus, low elongation, good heat
resistance stability, impact resistance, and is suitable for medium
and long distances. High tailoring, conveying materials under
high-speed conditions. It is used to transport materials in coal,
mine, port, metallurgy, electric power, chemical industry and other
fields. According to the performance of the cover rubber, it is
divided into cold-resistant type, acid-resistant type,
alkali-resistant type, oil-resistant type, wear-resistant type,
etc.
According to different use environments, rubber conveyor belts are
divided into rubber conveyor belts and include (common type,
heat-resistant type, flame-retardant type, burn-resistant type,
acid and alkali resistant type, oil resistant type), heat-resistant
conveyor belt, cold-resistant conveyor belt, acid and alkali
resistant Conveyor belt, oil-resistant conveyor belt and other
models. The minimum thickness of the cover rubber on the ordinary
conveyor belt is 3.0mm, and the minimum thickness of the lower
cover rubber is 1.5mm; the minimum thickness of the cover rubber on
the heat-resistant conveyor belt, cold-resistant conveyor belt,
acid and alkali resistant conveyor belt, and oil-resistant conveyor
belt is 4.5mm, and the lower cover The minimum glue is 2.0mm.
According to the specific conditions of the use environment, the
thickness of the upper and lower cover rubber can be increased by
1.5mm.
