Dimensional tolerance of basic inspection spot mark on the surface of insulating rubber sheet by the manufacturer of insulating rubber pad

The rubber of insulating rubber sheet comes from the latex of rubber tree and other green plants. The high ductility of rubber has become a reason for the selection of insulating rubber sheet. The excellent ductility makes the insulating rubber sheet not easy to break in the whole process of paving, and has excellent flexibility and ductility. What is its acceptance criteria? Let's introduce the manufacturer of the lower insulating layer rubber pad.
Because of its wide content, rubber has very good processing performance. It has good dispersibility and co solubility with mutual compounding agent, and is easy to be used with filler and most other rubbers. It is also convenient for injection molding, press out and other mechanical processing and adhesive forming.
The deep layer or height width ratio of the basic inspection mark or convex concave part of the surface layer of the insulating rubber sheet shall not exceed the dimensional tolerance of the thickness of the rubber sheet. There shall be no more than five bubbles per square meter of the total area of the bubbles. The spacing between two bubbles at random shall not be less than 40mm. The deep layer and length of the residue shall not exceed the thickness of the rubber sheet and shall not be less than 40mm, The edge of the rubber plate is uneven or honeycomb, and the total width of the part is not more than 11mm, and the length is not more than 1 / 10 of the total length of the rubber plate, and cracks are not allowed.
