Q:What are the applications of rubber airbags in the automotive field
In 2007, China's auto production and sales were 8 million 882 thousand and 400 and 8 million 791 thousand and 500, respectively, an increase of 22.02% and 21.84% respectively. According to forecasts, by the year 2010, sales will exceed 10 million vehicles, with an average growth rate of 12%, when China's car ownership will reach 91 million vehicles. This will undoubtedly give the automotive industry related rubber industry, both production and supply, or social maintenance services to provide a huge market
Q:How to test the abrasion resistance of rubber?
As long as the amount of carbon black is added, the wear resistance will be increased. Have the Akron abrasion resistance test (the rubber disc shape small rubber wheels on the wheel rotating friction, turn a lap after the contrast test before and after the rubber wheel quality, poor quality of smaller, better resistance).
Q:How to solve the exhaust problem in rubber vulcanization process
It is mainly divided into two kinds of natural rubber and synthetic rubber. Natural rubber is made from rubber, rubber and grass. Synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or in all fields of life. It has a wide range of uses. [1] can also be divided into rubber with natural rubber, general rubber, styrene butadiene rubber, nitrile rubber, silicone rubber, butadiene rubber, butyl rubber, EPDM rubber, chloroprene rubber types.
Q:What are the causes of chapped rubber products?
Rubber aging is a common problem of rubber products, and aging is mainly due to internal structure or component is easy to aging due to weakness, such as unsaturated double bond, branched, carbonyl, hydroxyl and so on; at the end, the main external or environmental factors are sunlight, oxygen, ozone, heat, water and mechanical stress force, high energy radiation, electricity, industrial gas, water, salt fog, fungi, bacteria, insects etc.
Q:Can rubber products be injection molded and plastic injection functions?
Rubber is an elastic polymer. Rubber can be obtained from the plant sap, can also be man-made, both have many applications and products, such as tires, washers, etc., has become an important economic crop. The cultivation of rubber is mainly concentrated in Southeast Asia, such as Thailand, Malaysia and Indonesia.
Q:How to clean rubber products?
Rubber products aging test belongs to the category of aging test, rubber aging refers to rubber and products in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors caused by the performance of the structure change, then the loss of use value phenomenon. They are crazing, sticking, hardening, softening, powdering, discoloration, mildew, etc..
Q:What gum does rubber and metal stick together?
The cohesion of JL-518 silicone rubber heat vulcanization glue: is a new high performance silicone primer. For the bonding of silicone rubber, TPU and aluminum, iron, copper, stainless steel and other metal nylon cloth special adhesive, in particular for the preparation of silicone rubber rollers and composite rubber products, its performance is better than other similar products, the role of shear bonding surface can withstand long time twist extrusion stress. The preparation of ordinary rubber rolls and compound rubber products such as ethylene propylene rubber also has good effect. Non-toxic, no harmful solvents, comply with environmental protection requirements, no adverse effects on human health.
Q:What about the Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM)?
The Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM) are approximately:Rubber elastic modulus 0.0078GPa, Poisson's ratio 0.47.
Q:What plastic rubber will not be subjected to oil (such as transformer oil) by quality (e.g., aging, dissolution)?
The most essential difference between plastics and rubber is plastic deformation when plastic deformation occurs, while rubber is an elastic deformation. In other words, it's not easy to restore the original state after plastic deformation, and rubber is relatively easy. Plastic elasticity is very small, usually less than 100, while rubber can reach 1000 or more. Most of the molding process of plastics is finished
Q:Explain why butyl rubber is more resistant to oxidation and aging than other elastomers, such as natural rubber
Usually smoked rubber, crepe, dry glue, glue... Etc.. The dry glue without smoke and natural rubber, color to dry shallow, suitable for light and color products
