Q:How does the rubber part of the watch become yellow?

Rubber: the word "rubber" comes from the Indian language "cau-uchu", meaning "weeping tree"". Natural rubber is flowing out from the Hevea latex when tapping after solidification and drying process. The finished product is material with elasticity, insulation, waterproof and air.

Q:Bought a mouse pad, a little rubber, how to remove?

Rubber deodorant can effectively reduce or eliminate the odor or odor caused by rubber additives and rubber residual monomers in rubber products. It is especially suitable for some rubber products which use two times to reprocess and reprocess. The rubber deodorant has excellent temperature resistance, long aging and small amount of addition. It does not affect the performance of the rubber products which need to be covered or flavored.

Q:What are the bridge rubber air bags used for?

Open the valve, inflated to the specified pressure, you can close the valve, must not exceed the pressure.

Q:What is the composition of the vulcanizing agent for silica gel?

Vulcanizing agent is organic peroxide, or bridging agent, used for curing silicone rubber (Xi Likang), EVA and curing of unsaturated polyester.

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:How do rubber undergo vulcanization?

Rubber vulcanization is a chemical reaction process, before vulcanization rubber is present in a linear molecular form, is the linear sulfide molecules through some other substances (such as sulfur and peroxide) connected together to form a three-dimensional network structure. Sulfur must not be used with sulfur material, as long as the rubber linear molecules can be linked together to form a body shape on the lineEach rubber formulation has an optimum curing temperature, which increases the speed of vulcanization within a certain range, but the performance of the product decreases

Q:Rubber rolling process for making rubber products

The rolling process has become a rolling process.The principle of rolling process: using pressure between the calender roller, the material plastic flow deformation, the final film made with the size and geometry of the provisions of section a section, or the rubber covering process in textile or fabric made of metal surface has a certain thickness of the tape section.

Q:What is the harm of rubber to the human body?

In use, some contact with the human body rubber requirements are very high, from the choice of gum species (usually silicone rubber and PU), to the use of mixing agents, have strict requirements.

Q:What kind of material does the shockproof rubber cushion usually choose? What's the hardness?

The air tightness of butyl rubber is the best of all the rubber, is its biggest advantage, it is mainly used for tyres, although there are shock absorbing function, but dynamic flex is not ideal.
