Q:What is a rubber accelerator? What role?

The accelerator for natural and synthetic gums has a broad range of vulcanization, which can be used alone or in combination with two dithiocarbamate, glucosinolates, guanidine, and other basic promoters. Mainly used in the manufacture of tires, adhesive tape, rubber shoes and other industrial rubber products.

Q:What problems need to pay attention to when inflating the pipe?

The charging pressure does not exceed the working pressure of the air sac, and the sharp object is prevented from scratching the gasbag during the inflating process

Q:How to maintain and store the rubber material?

Rubber itself is a shelf-life, you can ask the supplier to warranty, above all, as fillers, such as calcium carbonate, carbon black, long time no problem, also have a shelf life of antioxidant promoter, especially individual species. When storing, pay attention to fire prevention, moisture-proof, away from the high temperature, avoid direct sunlight, of course, the general "first in first out" is a must follow the truth.

Q:How can the frictional properties of rubber improve?

The free energy of rubber surface determines the size of the interaction force between rubber and duality, and then affects the adhesive friction of rubber. Generally speaking, the friction coefficient increases with the increase of surface free energy.

Q:What's wrong with rubber whitening?

White: may refer to spray frost (dissolved in more than rubber, drugs in rubber migration to the rubber surface), 1 reasons, excessive drug formulation; 2, sulfur is not complete, the two plus sulfur solution (130 - to 1 hour);It may be a white filler in rubber, so there's no way out. It's only the formula;

Q:How to enhance the performance of water resistant silicone rubber products

Steam can also reduce the performance of silicone rubber / silicone products, essentially the fracture of the backbone. The hydrolysis fracture reaction becomes apparent due to the increase of temperature and the presence of ionic reagents.

Q:What are the disadvantages of a rubber roof?

The rubber roof house is very hot in summer because the rubber is airtight and airtight.

Q:How to improve the hardness of rubber?

General 90SHA or more need to use hard resin or high styrene such things, of course, have to properly adjust the strengthening agent and curing system

Q:What is rubber damping material?

Butyl rubber, butyl bromide and butyl chloride are the main ones!! Need to design, sell rubber products, can find me!

Q:What advantage does ethylene propylene rubber with three yuan compare to two yuan ethylene propylene rubber?

In recent years, the third monomer and new technology development, foreign developed 1 7- octadienoic, 6, 5, two 10- methyl -1, 9- eleven, 7- two three ene 3, methyl -1, 6- octadienoic, 5 7-, two methyl -1, 6- octadienoic, 7- methyl -1, 6- octadiene as the three EPDM third monomer, the performance of three Yuan rubber has been enhanced. The monomer and content of third monomer in three yuan ethylene propylene rubber have direct influence on vulcanization rate and vulcanizate property. Among them, dicyclopentadiene (DCPD) as the third monomer, although the price is low, but the three Yuan rubber vulcanization speed is slow, difficult and high degree of unsaturation diene rubber and use; to ethyiidenenorbomene (ENB), 6 10-, two methyl -1, 5, third monomer three Yuan rubber vulcanization speed 9- eleven three ene as fast, the former has become the main varieties of three yuan of ethylene propylene rubber. The third monomer content in iodine said three EPDM iodine value is generally 6-30, mostly around 15. The iodine value is 6-10, curing speed is slow, difficult and high unsaturated rubber; iodine value is 25-30, for ultra high speed curing type, available in any proportion and high unsaturated diene rubber and use. Therefore, three yuan ethylene propylene rubber and other rubber in use, should pay attention to choose the appropriate three yuan ethylene propylene rubber varieties.
