Acid and alkali resistant rubber sheet manufacturers teach you how to choose acid and alkali resistant rubber sheet
At present, there are many suppliers of acid and alkali resistant rubber sheet products in the market. When we choose acid and alkali resistant rubber sheet products, we can choose the type of rubber sheet that suits you according to your different needs and uses , How to choose a good quality, cost-effective acid and alkali resistant rubber sheet among many acid and alkali resistant rubber sheets? The following methods can be used for reference when you buy acid and alkali resistant rubber plates in the future.
First, check the appearance quality of acid and alkali resistant rubber sheet. First look at the color of the acid and alkali resistant rubber plate. The natural rubber plate is golden yellow and translucent. The carbonized rubber plate is bronze or brown. The color is uniform and shiny. With medium hardness, acid and alkali resistance. It can work in 20% acid (alkali) liquid with temperature between -30 ～ + 60oC. Uses: It can be used for punching various gaskets with good sealing performance with acid and alkali resistance requirements.
Second, check the paint quality of acid and alkali resistant rubber sheet. Place the floor in the light, and see if there are bubbles, pits, or orange peel on the surface, and then check whether the paint is rich, full, and flat. For example, the surface of the medium voltage plate is plated with purple and sold as a high voltage plate. Therefore, in addition to checking the appearance quality at the time of purchase, it is only necessary to measure the tensile strength. In the transverse direction of the board, take 3 samples of 200mm × 20mm and test it on a tensile machine to see if it is underfilled and cut corners.
Third, the inherent quality of acid and alkali resistant rubber board. First of all, the material can be used for hand and eye view. If the floor is lighter in hand, the insulating rubber board uses tender bamboo. If the texture is fuzzy, it means that the bamboo material Not fresh, it is older 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 based on nitrile rubber.
Fourth, to see whether the structure of acid and alkali resistant rubber plate is symmetrical and balanced, it can be cut from both ends of the rubber plate, whether it meets the principle of symmetrical balance, and if it meets the structure, it will be stable.
Fifth, see if the floor layer and the interlayer of the acid and alkali resistant rubber sheet are tightly glued with both hands, and whether there will be delamination. Silicone rubber has outstanding high and low temperature resistance, ozone resistance, and weather resistance. It can maintain its unique operating elasticity, ozone resistance, and weather resistance in the operating temperature range of -70 ° C to + 260 ° C. It is suitable for making thermal mechanisms. Sealing gaskets, such as strong light source lamp housing sealing gaskets, valve gaskets, etc.
The above is the selection method of acid and alkali resistant rubber sheet products. I hope you can help when you choose the products. I wonder if you understand? If you have any questions, please feel free to contact our company.
