The leakage of transformer occurs mostly around the gasket, which is mainly caused by the aging and cracking of gasket. The quality of depends mainly on its oil resistance. The poorer oil resistance, the faster aging rate. Especially under high temperature, the aging speed will be faster and easily lead to aging and cracking of gasket, resulting in oil leakage. When overhauling oil-resistant and h...
The characteristics of rubber foot mats are as follows: 1.The material is a high elastic polymer with reversible deformation. This kind of material makes rubber foot pads full of flexibility under room temperature, and below very small external force action they can produce bigger deformation and return to original state after removing external force. Synthetic rubber is a completely amorphous pol...
Perfluorinated rubber has three characteristics: First, high temperature resistance; Second, strong corrosion resistance. It has a strong dielectric performance in the acid and alkali environment; And the third is super cleanliness. Those characteristics make it widely used in the following fields: first, chemical processes and petroleum refining. In this field, perfluorinated rubber seals a...
Generally, we need to consider the following aspects when choosing rubber roller: 1.Drug resistance -- oil resistance and solvent resistance are usually required. We choose synthetic rubber according to the purpose. For example, printing rollers must be resistant to solvent, oil and acid, etc. 2.Physical properties --elasticity, flexibility, abrasion and other physical functions affect the service...
The cross section of rubber seal gasket is round and has certain self-tightening effect. The sealing effect is better than the flat gasket and the compressive force is smaller. From the aspect of material, the main products of rubber pad: silicone pad, nitrile rubber pad, fluoro rubber pad, other rubber pad. Rubber pads with oil resistance, acid and alkali resistance, cold and heat resistance, agi...
Despite the recent novel coronavirus outbreak being effectively controlled, the virus is still present and the underlying protective measures are very effective. Therefore, mask has become one of the necessary protecting things for people to travel. Especially in crowded places, it is very necessary to wear masks. The holder of silicone mask is made of food-grade silicone, the material of which is...
