The use of rubber can be large la in the national economy in all sectors almost all have its position. With all walks of life have close contact.
(a) rubber and transportation: rubber industry is developed with the automobile industry. In the sixties, the automobile industry and the petrochemical industry, high-speed development, so that the rubber industry production level has improved greatly; into the seventies, in order to adapt to the high-speed automobile, safety and energy saving, eliminating pollution, preventing the need for public health, and so on, to promote the new varieties of tires continue to come out of the view. Raw material rubber consumption in transportation occupies a considerable proportion. For example: a liberation spleen 4 tons of heavy vehicles, rubber products need more than 200 kilograms, a hard seat carriages need to be assembled rubber products weighing more than 300 kilograms, a 10,000-ton ship will need rubber products nearly 10 tons, a jet airliner needs nearly 600 kilograms of rubber. In the sea, land, air transportation, which are inseparable from the withdrawal of rubber products. As a means of transportation, tires are a major accessory. In recent years, in addition to the production of ordinary tires, but also vigorously develop radial tires, tubeless tires underground railways have also used rubber tires. Railroad vehicles and automobiles to promote the application of rubber spring reduction products, airtight rubber put. Large stores, stations, subways are also being used in the manned transportation belt. In addition, there are made of rubber "hovercraft", "hovercraft" and so on.
(ii) root and industrial mines: industrial sector needs large and small rubber products that are more, more varieties, wide range of uses, and some have special requirements. The main products are tapes, hoses, sealing gaskets, rubber rollers, rubber plates, rubber lining and labor protection products. In mining, coal, metallurgy and other industrial applications tape to transport finished products, everywhere in the emergence, in order to large-scale production of Xiao want, but also produced wire rope core transport belt and synthetic fiber transport belt. In recent years, mining mill rubber lining, forging rubber instead of manganese steel, service life increased two to four times, but also reduces the noise, this product Ba in the world to promote.
(C) rubber and agriculture, forestry and water conservancy: the development of agriculture, forestry and water conservancy, but also hail play a variety of rubber products, in addition to tractors and agricultural machinery with a variety of tires, in the combine harvester needs to be used in the rubber crawler, irrigation pools, water with the water with reservoirs using rubber seepage layer and rubber dams, rubber boats, life-saving supplies, etc., the use of staff are growing, in the agricultural and sideline product processing equipment and forestry, animal husbandry, fisheries, technical equipment, etc., have a rubber lining. Technical equipment, etc., there are rubber accessories. Such as an iron cattle a 40-type wheeled tractor, the need for rubber products as many as 121 pieces. With the mechanization of agriculture, farmland water conservancy development, the need for rafter wave products will be more and more.
(D) rubber and military solid defense: rubber is an important strategic materials, the application of military defense is very extensive, for example, a tank to use more than 800 kilograms of rubber; 30,000 tons of warships in general to use sixty-eight tons of rubber, almost military equipment, air force facilities, national defense projects have rubber footprints. The use of rubber made of ships, tents, warehouses and protective gear, water bath clothing and many other varieties. As for the perimeter defense cutting-edge technology needs of high temperature, low temperature, oil, high vacuum and other special properties of the rubber Constitution 0 product is indispensable. With the development of national defense modernization, the requirements can withstand -100 a 400 ℃ temperature range, and can resist a variety of acids, cities and oxidants with special properties of rubber, is being developed and produced.
(E) rubber and civil construction: modern construction, rubber is very useful. For example, the use of glass Zeus sealing rubber strips in buildings, soundproof flooring, piggyback sponges, rubber carpets, rainproof materials, as well as with milky paint coating theater walls. From the mid-sixties to install large rubber spring cushions in buildings to reduce the vibration and noise caused by the subway. Foreign countries are also trying to reduce the role of earthquake damage to the building of rubber cushions, the development of such rubber products is of great significance. Manufacture of hollow concrete components application of inflatable rubber soft rubber latex cement and rubber Chauqing in the construction project is becoming more and more widely used. Mixing latex into cement can improve the elasticity and abrasion resistance of cement. In the asphalt add 3% of rubber or latex paving road pavement, can prevent cracking of the road surface, and improve the impact resistance pieces. In the construction of the construction of the calendar use of machinery, transportation equipment, protective equipment, etc. are rubber products accessories.
(F) rafter limbs and electrical communication: another characteristic of rubber is good insulation, not easy to conduct electricity. A variety of wires, t handle cable more rubber is used into. Hard rubber is also used to make hoses, rubber rods, rubber plates, bulkheads and battery shells. In addition, it is also widely used as protective equipment insulated gloves, insulated rubber boots and shoes.
(VII) Root rubber and health care: In the medical and health sector there are many rubber products in the application, such as hospitals, anesthesiology, urology, surgery, neurosurgery, orthopedics, five palace science, radiology and other recruiting diagnostics, blood transfusion, urinary catheterization, gastrointestinal washing of a variety of rubber-colored surgical gloves, ice capsule, sponge cushions and so on are mostly rubber products. As accessories for medical equipment and instruments also have rubber products. Medical rubber products often have a special requirement for it, such as non-toxic, sterilization, physiological inertia, radiation resistance. Rubber towel of butyl rubber has a high degree of biological inertia, chemical stability and more slight water permeability and air permeability, used to process rubber bottle stoppers, can ensure high moisture absorption and anti-business and anti-cancer agent preservation. In recent years, silicone rubber in the manufacture of medical products more and more widely, such as the use of silicone rubber manufacture of artificial organs and human tissue substitutes have made great progress, but also use it to make drug capsules, into the body in the appropriate location, so that the capsule drugs slowly and continuously released, can improve the efficacy of treatment and relatively safe.
(H) rubber and commodity storage: rubber is not only used for medical cattle, but also applied to storage of fruits and vegetables. Since 1954 since the air-conditioning technology has made great progress, was rubber film widely used in silicone rubber Zeus air-conditioned storage of fruits. Silicone rubber has superior air permeability and appropriate air permeability ratio for Coa and 02. The ratio of the two is 6:1, that is to say: carbon dioxide diffusion rate through the silicone rubber window six times faster than oxygen. Than polyethylene plastic film into the carbon dioxide and oxygen about 200 times faster. According to different fruit and vegetable varieties of respiratory strength and the number of differences, made of various sizes of silicone rubber aegis dumplings embedded in the plastic film control, you can make the bag to maintain the right amount of c02, the formation of a good gas storage environment, thus inhibiting the respiratory strength of fruit and vegetables, delay the metabolism rate, delay the ripening of fruits and vegetables in the process of reducing the water evaporation to prevent rotting. From the storage of apple test comparison, using plastic film packaging storage for five months, natural consumption is o.7% below, the end of the natural consumption of up to 5.83%. Again, with silicone rubber film Zeus air-conditioned preservation of western red against all the green by a month of good fruit rate of more than 70%, weight loss of 3.6%, take out all the fruit can be normal red ripening. Do not use the air-conditioning account of tomatoes within a week to red ripe, can not be stored again.
(IX) root rubber and education and sports: a variety of common ball gall bladder, ping-pong paddle sponge rubber surface, swimming foot manic, toy ball, gold pen gall bladder, rubbing erasers, rubber traps, rubber thread, rubber stamps, rubber cloth, balloons and sponge cushions, etc., are widely used in education and culture institutions, offices, design and drawing, and sports equipment, and so on.
(J) rubber and household goods: daily life there are many rubber products in our service, all over the urban and rural residents to wear, it is B with a large consumption of rubber products. Others, such as raincoats, hot water aid, loose purple belt, children's toys, sponge seat cushions and latex impregnated products, etc., in people's lives are playing its role.
