Q:How do you remove the black dirt on the rubber?
You should be rubber silicone, most of all is blackTry rubbing it with diluted alcohol.
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:How can I get rid of the rubber?
One way is to use rubber deodorant is a kind of used to remove or reduce the acid degradation, all kinds of rubber produced in the processing or in the process of the use of alkoxy compounds, aldehydes, vinyl compounds, ammonia, CO2 plastic smell of chemical additives, the smell if inhaled for a long time will stimulate the senses give a person, discomfort or even harmful to the body, have two times of pollution to the environment, the chemical composition of different varieties of rubber and odor molecules are different, and in the actual development of Chinese ocean chemistry and etc. Ma'anshan Keli chemical is used in chemical chelation is also used, is the other mechanism, in addition to taste rubber both the rubber agent itself, also want to consider a variety of additives such as odor curing agents released, in addition to the use of rubber ingredients to improve rubber products and improve the level of environmental protection, rubber The production environment is of great help to the comprehensive utilization of regenerated rubber resources. A form of powder or liquid used in rubber, usually based on odor and odor characteristics
Q:Rubber soaked with hot water will not come out harmful substances?
Chloroprene rubber chloroprene as the main raw material, made by homopolymerization or copolymerization of small amounts of other. Such as high tensile strength rubber, heat resistance and light resistance, aging resistance and oil resistance properties are superior to natural rubber, styrene butadiene rubber, butadiene rubber. It has a good flame resistance and excellent resistance to burning, its chemical stability is high, water resistance is good
Q:Is work in rubber products harmful to health?
The raw material of rubber products is rubber compound, and the rubber compound has five components:Main rubber. Rubber main glue is not toxic.Reinforcing agent. Most of the reinforcing agents are not toxic.Softener. Is the most emollient mineral oils, high temperature volatile hazardous substances.Antioxidant. Some poisonous.Vulcanizing agent. The vulcanizing agent is generally sulfur, sulfur will release a high temperature sulfur dioxide, sulfur dioxide, sulfur dioxide, hydrogen sulfide gas three.
Q:What is the rubber composition and function of the airplane tyres?
Rubber is divided into natural rubber and synthetic rubber. Natural rubber is mainly derived from the Hevea tree. When the epidermis of this rubber tree is cut open, it will shed milky juice. It is called latex, and the latex will be natural rubber when it is condensed, washed, molded and dried. Synthetic rubber is made by synthetic methods, and different kinds of rubber can be synthesized with different raw materials (monomers). Between 1900 and 1910, chemist C.D. Harris (Harris) measured the structure of natural rubber as a polymer of isoprene, which opened the way for synthetic rubber. In 1910, Russian chemist SV Lebedev (Lebedev, 1874 - 1934) with sodium initiator 1, sodium 3 - butadiene rubber polymerization into small, then there are many new varieties of synthetic rubber, such as polybutadiene rubber, chloroprene rubber, styrene butadiene rubber and so on. The yield of synthetic rubber has greatly exceeded that of natural rubber, of which the largest yield is styrene butadiene rubber. General rubber glue refers to replace some or all use such as natural rubber, styrene butadiene rubber, butadiene rubber, isoprene rubber, mainly used in the manufacture of tyres and rubber products industry. General purpose rubber is in great demand and is the main variety of synthetic rubber. Styrene butadiene rubber styrene butadiene rubber [1] is made by copolymerization of butadiene and styrene. It is the largest synthetic rubber with milk, styrene butadiene rubber, styrene butadiene rubber and thermoplastic elastomer (SBS).
Q:How to enhance the performance of water resistant silicone rubber products
The purity of the filler and the amount of catalyst residue have great influence on the purity of the filler. In order to improve the steam resistance of silicone products / silicone rubber products, can be used to increase the crosslinking density and the hydrophobic filler method in silica raw material formulation, but should try to avoid the silicone rubber / silicone products using high pressure water vapor over 2MPa under. With this characteristic, the co vulcanizate of siloxane ethylene propylene rubber blends is the best.
Q:What about the Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM)?
Three yuan ethylene propylene rubber is ethylene, propylene and non conjugated diene three yuan copolymer, began commercial production in 1963. The consumption of the whole world is 800 thousand tons every year. The most important feature of EPDM is its superior oxidation resistance, ozone resistance and corrosion resistance. Because three yuan ethylene propylene rubber belongs to polyolefin family, it has excellent curing property. Of all rubbers, EPDM has the lowest specific gravity. It absorbs large amounts of fillers and oils and has little effect on properties. Therefore, rubber compounds with low cost can be made.
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:Is the odour emitted by industrial rubber poisonous?
The rubber shaped blank after extruding; and then the textile materials and rolled hanging glue or glue (or metal) together formed into semi-finished products; finally after vulcanization will have final semi-finished products made of high elastic plastic.Most of the ingredients are organic substances, volatile, containing toxic, harmful and highly carcinogenic NOBS.
