The national standard for industrial rubber floor mats is GB/T5574-2008.This is a very important standard,mainly including physical performance,chemical performance and appearance quality and other aspects of the indicators and requirements.These indicators and requirements are directly related to the quality and performance of the rubber floor mats.Through reasonable design and selection,it can meet the different needs in different industries and improve the efficiency and reliability of application.
Tensile strength is an important indicator of industrial rubber floor mats.What are the factors affecting the tensile strength of industrial rubber floor mats?
第一的,considering the formula design,mainly the varieties of raw rubber.The varieties and dosage of vulcanization system and filler.The high tensile strength formula should adopt crystalline rubber such as natural rubber,chloroprene rubber or chlorosulfonated polyethylene,and the rubber content is generally about 60%.
第二,select active filler(such as carbon black.White carbon black),and disperse evenly when mixed.When using active filler as a supplement,it should be used properly.
第三,the tensile strength is related to the structure of rubber.When the number is small,the sub-value of intermolecular interaction is small.Other factors affecting the intermolecular force will affect the tensile strength.
Fourth,the tensile strength of industrial rubber floor mats is also related to the root temperature.The tensile strength at high temperature is far lower than that at room temperature.The tensile strength is related to the crosslinking density of the root.With the increase of crosslinking density and tensile strength,the crosslinking density will continue to increase after the maximum value,and the tensile strength will decrease significantly.
