Depending on the environment and the requirements of many different sizes and types are divided into: 1. In accordance with the customer by width can be easily cut; 2. the use of different environments, and includes a conveyor belt into ordinary (common type, heat-resistant, flame-type , anti-burning type, acid type, oil type), resistant conveyor belt, cold conveyor belt, acid and alkali conveyor belt, oil conveyor belt, food conveyor models. Wherein the plastic cover on the lowest common food conveyor belt conveyor and a thickness of 3.0mm, under the plastic cover a minimum of 1.5mm; the thickness of the plastic cover on the lowest heat conveyor belt, cold conveyor belt, acid and alkali conveyor belt, oil conveyor belt is 4.5 mm, Bottom plastic cover a minimum of 2.0mm. Depending on usage environment can be used to increase the thickness of 1.5mm plastic cover from top to bottom; 3. A conveyor belt fabric layer tensile strength divided into ordinary conveyor belt, steel cord conveyor belt. Powerful into nylon canvas conveyor belt conveyor (NN conveyor belt) and polyester conveyor belt (EP conveyor belt). Additional information: strong layer of strong polyester canvas conveyor belt (EP), also divided into type EP100, EP150 type, EP200 type, EP250, EP300 type, EP350 type, EP400 type, etc; can also be nylon canvas (NN) It can be divided into NN100, NN150, NN200, NN250, NN300, NN350, NN400, NN450, NN500 type. Products ⑴, general conveyor belt (including high-strength nylon conveyor belt) Product Executive GB7984-2001 standards. General conveyor belt: overlay: tensile strength of not less than 15Mpa, elongation at break of not less than 350%, the amount of wear ≤200mm3, interlayer adhesion strength between the average value of the longitudinal sample fabric layer is not less than 3.2N / mm, plastic cover and between the cloth layer is not less than 2.1 N / mm full thickness longitudinal elongation at break of not less than 10% full thickness longitudinal reference force the elongation is not more than 1.5% nylon (NN), polyester (EP) conveyor belt: overlay : tensile strength of not less than 15Mpa, elongation at break of not less than 350%, the amount of wear ≤200mm3 layer between the adhesive strength between the average value of the longitudinal sample fabric layer is not less than 4.5N / mm, covered with a cloth between the rubber layer is not less than 3.2 N / mm full thickness longitudinal elongation at break of not less than 10%, with reference to the full force of the longitudinal elongation of not more than 4%. ⑵, three anti-conveyor (heat, acid, alkali) product implementation HG2297-92 standards. ⑶, fire-retardant conveyor belt perform MT147-95 standards.
