Qingdao polyester high strength lifting belt

The lifting belt, also known as the rubber lifting belt, is made of multi-layer rubber fabric
Generally, the belt core should be covered with rubber
It can be divided into heat-resistant lifting belt and ordinary lifting belt according to the use temperature; According to the different materials of the belt core, it is divided into all cotton, polyester cotton interweaving, nylon and EP lifting belt
1、 The physical properties and grades of the covering rubber can be divided into strong wear (D type), moderate wear (L type) and heat-resistant (T type) for conveying high-temperature materials according to the wear and load of the conveyed materials
2
The width specification of the lifting belt: 150, 200, 250, 300, 350, 400, 500, 600mm and other types of lifting belts: retaining edge lifting belt, whole core lifting belt, skirt edge lifting belt, vertical lifting retaining edge conveyor belt, steel wire rope lifting belt, tear proof lifting belt, cotton canvas lifting belt, Polyester high strength lifting belt
3、 Technical requirements for lifting belt: 1 See the following table for physical parameters of covering glue:

project		indicators
		type D	type L
tensile strength mpa&ge		18 0	15 0
elongation at break%&ge		400	350
hot air aging performance	tensile strength change rate%	-25-25
70 ℃ x7d	change rate of elongation at break%
abrasion cm		0 7	0 8

note: for special purposes or conveying sharp abrasive materials, the physical properties of the covering rubber can be determined through negotiation
The covering rubber performance of heat-resistant (T-type) tape shall comply with hg/t2297< Tropical resistance > Provisions of
2
the longitudinal tensile strength of the belt shall not be lower than the following nominal values: 1001251602002503154000n/mm, etc
3
the longitudinal full thickness elongation at break of the belt shall not be less than 10%, and the elongation at reference force shall not be greater than 4%
