How many layers of rubber band are glued together?
Three conveyor belts(heat resistant, acid resistant, alkali resistant) products comply with HG2297-92 standard.Flame retardant conveyor beltProduct execution MT147-95 standards.Conveyor belt: it is the main component for dragging and carrying material. When choosing, it adopts cotton canvas, polyester canvas or nylon canvas according to the tension. The other parts of the conveyor design meet all kinds of strong requirements, conveyor belt connection in accordance with different working conditions, mechanical joints, cold glue joints, vulcanizing joints, flexible selection.
Niron (NN) and polyester (EP) conveyor belts:The average adhesive strength between the layers is not less than 4.5N/mm, and the ratio between the coating and the cloth is not less than 3.2 N/mmFull thickness longitudinal elongation of not less than 10%, the thickness of longitudinal reference force elongation is not greater than 4%
Plain belt(with high strength nylon conveyor) products perform GB7984-2001 standards.Cover: the tensile strength of not less than 15Mpa, tensile elongation of not less than 350%, the wear is less than 200mm3, bonding strength between the layers is not less than the average value of the longitudinal 3.2N/mm layers of cloth, cover rubber and cloth layer is not less than 2.1 N/mmFull thickness longitudinal elongation of not less than 10%, the thickness of longitudinal reference force elongation is not greater than 1.5%
