- Q:What is the size of the scorch time of the rubber?
- Rubber scorch characteristics usually use 120 degrees Mooney scorch time Ts said, also available vulcameter determining curing curve on the T10 or TA1, TA2 said, the scorch time and process, the rubber accelerator process conditions, the hardness of the rubber material and rubber material return use and other factors. Generally soft rubber is 10-20min; most of the stock (excluding high filling hard or high temperature 35-80min) is 20-35min; the high filling hard material is.
- Q:What is rubber leather?
- The general rubber has good comprehensive properties and is widely used. The main contents are as follows: natural rubber. From the latex of the Hevea tree, the basic chemical composition is cis polyisoprene. Good elasticity, high strength and good comprehensive performance. Isoprene rubber. The full name is cis -1, 4- polyisoprene rubber, a high CIS synthetic rubber made from isoprene, because of its structure and properties similar to natural rubber, it is also called synthetic natural rubber. Styrene butadiene rubber. Referred to as SBR, made by copolymerization of butadiene and styrene. According to the production method, emulsion polymerization, styrene butadiene rubber and solution polymerized styrene butadiene rubber are divided into emulsion polymerization. Its comprehensive properties and chemical stability are good. The br. The full name is cis -1, 4- polybutadiene rubber, referred to as BR, made from butadiene polymerization. And the other than universal rubber, vulcanized butadiene rubber cold resistance, abrasion resistance and excellent elasticity, dynamic load, less heat, good aging resistance, easy and natural rubber, chloroprene rubber, nitrile rubber and etc..
- Q:Is polyurethane and polyurethane rubber one thing?
- Polyurethane and polyurethane rubber are one thing. Because polyurethane has good resilience, it is often called polyurethane rubber, also known as polyurethane elastomer.Polyurethanes are polymerized from polyesters (or polyethers) and two isopropyl esters. Good wear resistance, followed by good elasticity, high hardness, oil resistance, solvent resistance. The disadvantage is heat aging, poor performance. Polyurethane rubber is the most widely used in automobile, shoemaking and machinery industry.Whether polyurethane should be classified as plastic or rubber depends on the actual situation.
- 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 is the pressure on rubber products during vulcanization?
- It can be seen that the vulcanization time can be shortened by increasing the sulfuration temperature. The process of high temperature vulcanization is injection vulcanization and electric heating flat vulcanization. Both of them can be cured at 160 DEG C or even higher. In recent years, the industry has also adopted the trend of high temperature vulcanization. In addition, the continuous vulcanization process using eutectic liquid as heating medium has also begun to use high temperature vulcanization. In the rubber injection molding process, because the rubber material has passed the preheating and plasticizing of the screw, higher vulcanization temperature (such as 175~183 DEG C) can be adopted, but the reversion or sulfuration of rubber is less affected. For example, for three yuan ethylene propylene rubber, when set 160 degrees for molding, the positive curing time is 60min, if it is changed to 200 degrees noteThe time of vulcanization is only 4min. With the use of general-purpose rubber to make small products, the vulcanization time can be l-2mm.
- Q:Aging of rubber parts for automobiles
- Automobile rubber parts aging factors are: oxygen, ozone, heat, light, mechanical stress, moisture, oil, other chemicals or radiation, etc.. Attention should be paid to water and oil here:The alternate action of high temperature and oxygen 1. long-term water and in the external environment under the accelerated aging of rubber;2., the oil will penetrate the rubber, so that swelling occurs, rubber performance will be reduced. Therefore, trucks should avoid shock absorption of rubber bushings, oil and diesel in various occasions, including maintenance.
- Q:What kind of rubber products are expensive?
- The size and size of rubber products determine the amount of glue used, which is a matter of cost;
- Q:What are the uses of rubber oil?
- Also can be used for chloroprene monomers such as polymerization inhibitor, antiseptic coating waterproof material, such as veterinary medicine.
- Q:Is silicone good or rubber good?
- If it is inorganic silica gel, that does not need to compare. How do you put different kinds of things together, or do you say good fruit or electric fans? If organic silicone, then the outlook is good, but can not simply say better than ordinary rubber and bad, different places have different applications.
- Q:How do ordinary NBR and EPDM materials differ?
- Nitrile rubber (NBR) is composed of butadiene and acrylonitrile was prepared by emulsion polymerization, nitrile rubber by emulsion polymerization at low temperature, excellent oil resistance, high wear resistance, good heat resistance, strong adhesion. Its disadvantages are low temperature resistance, poor ozone resistance, poor insulation properties, and slightly lower elasticity. Nitrile rubber is mainly used in the manufacture of oil resistant rubber products.
