When we purchase rubber sheets, we can choose the type of rubber sheet that suits our needs according to our different needs and uses. So how can we choose good quality and cost-effective rubber sheets among many rubber sheets? The following methods, when you buy rubber sheets in the future, can be used for reference.
First, check the appearance quality of the rubber sheet. First look at the color of the rubber sheet, 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. It has medium hardness and acid and alkali resistance. It can work in an acid (alkali) liquid with a temperature of -30 ~ +60oC. Uses: It can be used to make a variety of gaskets with good sealing performance with acid and alkali resistance.
Second, check the paint quality of the rubber sheet. 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. For example, the surface of the intermediate plate is plated with purple and sold as a high pressure plate. Therefore, in addition to checking the appearance quality at the time of purchase, the tensile strength can be mainly determined. In the horizontal direction of the sheet, 3 pieces of 200mm × 20mm samples were taken and tested on the tensile machine to see if it was shoddy and cut corners.
Third, the inner quality of the rubber sheet First look at the material can be used hand rub and eye view, if the floor is lighter in the hand, the insulating rubber board shows the use of tender bamboo; if the texture of the eye is blurred, it means that the bamboo is not fresh, It is a relatively old bamboo. Nitrile rubber 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, the structure of the rubber sheet is symmetrically balanced from the two ends of the rubber sheet, whether it conforms to the principle of symmetrical balance, and if it conforms to the structure, it is stable.
Fifth. See if the rubber layer’s floor layer and the layer are glued tightly with two hands, whether there will be delamination. Silicone rubber has outstanding resistance to high and low temperature, ozone and weathering resistance. It can maintain its unique elasticity, ozone resistance and weather resistance in the operating temperature range of -70 ° C to +260 ° C. It is suitable for making thermal mechanism. The required gaskets, such as strong light source lamp cover gaskets, valve pads, etc.
