- 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 can the frictional properties of rubber improve?
- The viscoelastic parameter tan delta has a direct influence on the friction force, while the decrease of the rubber cross degree makes the tan delta increase. Therefore, the friction coefficient increases, and the friction coefficient and wear increase as well. From a physical and chemical point of view, the weaker the cross-linking, the higher the rate of wear is due to a lower degree of cross-linking which is easily caused by mechanical stress. It is found that the crosslinking degree of ethylene propylene three - element rubber increases with the irradiation of electron beam, which reduces the friction.
- Q:Natural rubber, general rubber, synthetic rubber. Are these all rubber products?
- Not rubber products, rubber classification, rubber is divided into natural and synthetic rubber, synthetic rubber and general rubber and special rubber! The so-called rubber products refers to the use of rubber as raw materials to produce products, such as tires, belts, conveyor belts and so on.
- Q:How can rubber and mould not be bonded when producing rubber products?
- Mold release can not be solved, we can only start with the mold structure. Because the main reason for adhesion is the complex structure of the product, resulting in strong vacuum adsorption between the mold and the mold. In view of this, we can do a few more exhaust at the appropriate location of the mold. If allowed, you can also modify the product structure, of course, this is unlikely. But really can not do it, this is the best solution.
- Q:Is work in rubber products harmful to health?
- Work in a rubber factory is harmful to health.When the rubber vulcanization molding, high temperature reaction releases sulfur dioxide, sulfur dioxide, sulfur dioxide, hydrogen sulfide gas three. If the workshop dust suction measures are not enough, these gases will pollute the workshop environment, workers will suck into the body, endanger health.
- Q:How can rubber be made into rubber when it is made?
- Rubber made of rubber products, to be mixed, vulcanized, trimming and many other processes to make rubber products, is a complex processing plant produced.
- Q:What is the role of softening plasticizers in rubber? How are they classified?
- Plasticized formulations can also classified by the sources of petroleum, coal tar plasticizer plasticizer, turpentine, plasticizer, plasticizer and synthetic fatty plasticizer.
- Q:Is silicone good or rubber good?
- Rubber is divided into natural rubber and synthetic rubber, natural rubber structure is isoprene polymer, synthetic rubber such as polybutadiene rubber, chloroprene rubber, styrene butadiene rubber. When rubber is deformed by the external force, the crosslinked rubber has the ability to recover quickly, and has good physical and mechanical properties and chemical stability.Silicone rubber is mainly composed of high molecular weight linear polysiloxane. The Si-O-Si key is the basic bond formed, mainly methyl silicon atoms connected, introduced a very small amount of unsaturated groups in side chain, intermolecular interactions, molecular spiral structure, methyl arrangement and can freely rotate outward, thus vulcanized silicone rubber has excellent resistance to high and low temperature (-100~315 DEG C). Weather, water repellent, electrical insulation, physiological inertia and other characteristics, are widely used in military, medical, industrial and agricultural production and people's daily life. Most importantly, there is no toxicity, as usual in pacifiers and breast implants.
- Q:What is rubber leather?
- Special rubber refers to rubber with some special properties. The main contents are as follows: chloroprene rubber. CR, prepared by polymerization of chloroprene. With good overall performance, oil resistance, combustion resistance, oxidation resistance and ozone resistance. But its density is larger, it is easy to crystallize at room temperature, hard to store, cold resistance is poor. Nitrile rubber. Referred to as NBR, made by copolymerization of butadiene and acrylonitrile. Good oil resistance and aging resistance. It can be used in the air of 120 degrees Celsius or in the oil at 150 degrees centigrade for a long time. In addition, it also has water resistance, air tightness and excellent adhesive properties. Silicone rubber. The backbone consists of alternating atoms of silicon and oxygen, with organic groups on silicon atoms. High and low temperature, ozone resistance, good electrical insulation. Fluorine rubber. A synthetic rubber containing fluorine atoms in the molecular structure. Usually, the number of fluorine atoms in the fluorine containing unit in the copolymer is expressed as fluorine rubber 23, and the copolymer is two vinylidene fluoride and three fluorine vinyl chloride. Fluorine rubber, high temperature, oil resistance, chemical resistance. Polysulfide rubber. Condensation of two halides with sulfides of alkali or alkaline earth metals. Has excellent oil resistance and solvent resistance, but the strength is not high, aging resistance, poor processability, odor, and more with nbr. In addition, there are polyurethane rubber, epichlorohydrin rubber, acrylic rubber and so on.
- Q:What are the disadvantages of a rubber roof?
- Sunlight causes aging of rubber. Tensile strength, elongation at break, impact strength, flexural strength, compression ratio and elasticity decrease.
