Rubber sheet surface acceptance standards and requirements

The source of rubber plywood is rubber tree and other sheets of latex, rubber elasticity has become the first reason for the choice of rubber sheet, good elasticity so that rubber plate in other process such as paving, and has a good stretch and extension. Because of its wide molecular weight distribution, it has good processing process performance. It is good in dispersion and cosote with the adhesive, easy to mix with fillers and most other rubber, easy to press, press and paste and other mechanical molding.

The surface foundation of the rubber sheet detection plywood spot marks or bumps should not exceed the thickness tolerance of the plywood, bubbles per square meter, the area of not more than 1cm2 bubbles not more than 5, any two bubbles between the distance is not less than 40mm, wherein the depth of impurities and length not more than 40mm of plywood thickness, The edge of the plywood is uneven or the spongy part is not more than 10mm wide, the length does not exceed 1/10 of the total length of the plywood, and no cracks are allowed.
