According to insulation rubber kraal pad small make up to know, today's rubber industry, true and false hybrid, difficult to difference between technology development and advancement of the industrial products, insulation rubber kraal mat also appeared a lot of kinds, the kinds of the above the market various brands of insulating rubber kraal pad has a lot of, so we should how to distinguish, small make up to make a brief introduction of the rubber insulation rubber kraal pad quality inspection standards. Insulating rubber kraal mat quality standard: appearance: spot mark or uneven: depth or height shall not exceed the rubber gasket thickness tolerance; Bubble: in every square metre, the area is not in 1 cm2 bubble is not more than 5, the distance between any two bubbles is not less than 40 mm; Impurities, depth and length of no more than rubber gasket thickness is not less than 40 mm; The edge is not neat or sponge: width does not exceed 10 mm, length is not less than 1/10 of the rubber gasket chief; Crack: there is no group 1, group and sampling in 30 t the same type of plastic board for a batch. Half yield less than 30 t, to half for a batch production. Each batch randomly take 10 volume size and surface quality inspection first, and then pulled out a roll of random from 10 volumes, from a distance of 30 cm end up enough sample physical performance inspection. 2, type 2. 1 all inspection items listed in this standard are the type of technology to SEO optimization o inspection items. Under normal circumstances, the hot air aging, heat resistant, low temperature resistance and other projects, once every quarter inspection, resistant to ozone test once every six months. 2. 2 decision rules of the specifications of the rubber kraal pad size and surface quality of sampling volume and the above methods. Physical properties of test for an indicator does not meet the requirement, it should be another double specimen, the second interview, still do not meet the requirements, then the batch or for nonconforming product during this period.
