Check the appearance quality of rubber sheet.First look at the color of rubber sheet, endowed with the yellow color of rubber sheet, the whole body bright, carbonized rubber sheet is bronze or brown, uniform color and luster.With medium hardness, acid, alkali resistance.Work in acid (base) liquids at temperatures from -30 to 60 ℃ up to 20 percent.Usage: it can be used for punching various kinds of gaskets with good sealing function required by acid and alkali resistance.
Check the paint quality of rubber sheet.Place of floor place light, see its surface without bubble, hemp dot, orange peel phenomenon, see its lacquer face again whether rich, full, level off.For example, in the middle pressure plate surface plating purple, as high pressure plate for sale.Therefore, in addition to the inspection of appearance quality when buying, the first measure of tensile strength can be.
In the plate transverse, intercept 200mm×20mm sample 3, in the tension machine inspection, can be clear whether it is cut corners.
Rubber has excellent resistance to fuel oil and aromatic solvent and other functions, but not resistant to ketone, ester and chlorinated hydrocarbon and other media, so oil-resistant seal products to choose rubber.From the two ends of the rubber sheet section to see whether the structure of the rubber sheet symmetric balance, whether in line with the principle of symmetric balance, if the structure is stable.
Tear with both hands to see whether the rubber floor layer and the glue between the layer is close, whether there will be stratification.Silicone rubber has excellent resistance to high and low temperature, ozone resistance and weather aging function, in the -70℃~ 260℃ operating temperature planning can adhere to its unique use of elasticity and ozone resistance, weather resistance, suitable for the production of heat arrangements required sealing gasket, such as strong light source lamp shade sealing ring, valve pad, etc.
