As we all known, rubber sheet is divided into adhesive rubber sheet, latex rubber sheet, hard rubber sheet, thick rubber sheet and so on. So how to choose a high-quality rubber sheet that suits you?
First of all, check the appearance quality of the rubber sheets. Then, looking at the color of the rubber sheets, the color of the rubber sheet is golden yellow, and the whole body is translucent. The carbonized rubber sheet is bronze or brown, and the color is uniform and shiny. Medium hardness, acid and alkali resistance. It can work in an acid (alkali) liquid with the temperature of -30 ~ +60℃.Uses: It can be used to make a variety of gaskets with good sealing performance and acid and alkali resistance.
Secondly, check the paint quality of the rubber sheets. Put the floor in the light, see if there are bubbles, pitting, orange peel on the surface, and see if the paint is rich, full and flat. Therefore, in addition to checking the appearance quality at the time of purchase, the tensile strength can be determined. In the horizontal direction of the rubber sheet, taking 3 pieces of 200mm × 20mm samples and testing on the tensile machine to see if it was shoddy and cut corners.
Thirdly, observing the inner quality of the rubber sheet. Firstly, Checking the material by hand rubbing and eye viewing. If the floor is light in the hand, the insulating rubber board is used of tender bamboo; If the texture of the it is blurred, it means that the bamboo is not fresh, it is a relatively old bamboo. Nitrile rubber sheet has excellent resistance to fuel oil and aromatic solvents, but it is not resistant to ketones, esters and chlorinated hydrocarbons. Therefore, oil-resistant sealing products are mainly made of nitrile rubber.
Fourth, observing the cross-section of both ends of the rubber sheet to confirm whether the structure of the rubber sheet is symmetrically balanced. If it conforms to the the principle of symmetrical balance, it is stable.
Fifth, observing if the rubber layer’s floor layer and the layers between each other are glued tightly, whether there are delamination. Silicone rubber sheet has outstanding resistance to high and low temperature, ozone and weathering aging resistance. It can maintain its unique flexibility, ozone resistance and weather aging resistance in the operating temperature range between -70 ° C and 260 ° C. It is suitable for making thermal equipment, required gaskets, such as strong light source lamp seal gaskets, valve gaskets, etc.
Six, inspecting if the manufacturers are standard, and the price is suitable. If the conditions permit, you can go to the relevant department for insulation test. The quality of insulation materials is especially important. Insulating rubber sheets are all have certain parameters .
