(1) The rafter rubber and transportation rubber industries developed with the automobile industry. The rapid development of automobile industry and petrochemical industry in 1960s greatly improved the production level of rubber industry. In 1970s, in order to meet the needs of high speed, safety, energy saving, pollution elimination and pollution prevention, new tire varieties were popularized. The consumption of raw rubber accounts for a considerable proportion in transportation. For example; A 4-ton spleen truck needs more than 200 kilograms of rubber products, a hard-seat carriage needs more than 300 kilograms of rubber products, a 10,000-ton ship needs nearly 10 tons of rubber products, and a jet airliner needs nearly 600 kilograms of rubber. Plastic products are indispensable in land, sea and air transportation. As a means of transportation, tires are a major accessory. In recent years, in addition to producing ordinary tires, radial tires and tubeless tires have been vigorously developed, and some underground railways have also adopted rubber tires. Rail vehicles and automobiles should promote the application of rubber spring expansion reduction products and airtight rubber releasers. Large shops, stations and subways are also using manned conveyor belts. In addition, there are rubber "hovercraft" and "hovercraft". (2) There are more and more rubber products of roots, limbs and industrial mines, which are needed by industrial departments, with many varieties and wide uses, and some have special requirements. The main products are adhesive tape, rubber hose, sealing washer, rubber roller, rubber plate, rubber lining and labor protection articles. In mining, coal, metallurgy and other industries, the application of tape to transport finished products is constantly appearing everywhere. For large-scale production, we also produce steel wire rope core conveyor belt and synthetic fiber conveyor belt. In recent years, using forged rubber instead of manganese steel has improved the service life of rubber lining plate of mining mill by 2 to 4 times and reduced the noise. This product has been popularized all over the world. (3) Rubber and the development of agriculture, forestry and water conservancy, agriculture, forestry and water conservancy, and various rubber products are also used. In addition to all kinds of tires used for tractors and agricultural machinery, the number of rubber tracks used for combine harvesters, rubber impervious layers and rubber dams used for irrigation pools, water heels and reservoirs, rubber boats, life-saving articles and other users is increasing, and rubber accessories can be used for agricultural and sideline products processing equipment and forestry, animal husbandry and fishery technical equipment. For example, a Tieniu -40 wheeled tractor needs as many as 12 1 piece of rubber products. With the great development of agricultural mechanization and irrigation and water conservancy, more and more products will be needed. (4) Rubber and military defense rubber are important strategic materials, which are widely used in military defense. For example, a tank needs more than 800 kilograms of rubber; Generally, 30,000-ton warships use 68 tons of rubber, and almost all military equipment, air force facilities and national defense projects have rubber footprints. There are also many kinds of boats, tents, warehouses, protective equipment and swimsuits made of rubber. As for the rubber products with special properties such as high temperature resistance, low temperature resistance, oil resistance and high vacuum required by the advanced shell technology, it is even more indispensable. With the development of national defense modernization, rubber with special properties, which can withstand the temperature range of-100-400℃ and resist various acids, cities and oxidants, is being developed and produced. (5) Rubber and civil architecture In modern architecture, rubber is more useful. For example, glass sealing tape for building, soundproof floor, green sponge, rubber carpet, rainproof material, latex paint to paint walls, etc. Since the mid-1960s, large rubber spring pads have been installed in buildings to reduce the vibration and noise caused by subways. Foreign countries are still trying to develop rubber mats to reduce the damage to buildings caused by earthquakes, and the development of such rubber products is of great significance. Inflatable rubber, soft rubber, latex cement, JIAOZHOU green, etc., which are used to manufacture concrete hollow members, are widely used in construction projects. Adding latex into cement can improve the elasticity and wear resistance of cement. Adding 3% rubber or latex to asphalt to pave pavement can prevent pavement cracking and improve impact resistance. Machinery, transportation equipment, protective equipment, etc. All rubber products used in building construction have accessories. (6) Rafters and electrical communication rubber are characterized by good insulation and are not easy to conduct electricity. All kinds of wires and T-cables are made of rubber. Hard rubber is also used to make hoses, sticks, plates, partitions and battery boxes. In addition, it is also widely used as protective articles, insulating gloves, insulating rubber boots and shoes. (7) Root gum and medical care There are many rubber products in the medical and health departments. Such as gloves, ice packs, sponge pads, etc. It is used in various rubber-colored operations such as anesthesia, urology, brain surgery, orthopedics, fifth uterus, radiology, blood transfusion, catheterization, gastrointestinal lavage, etc. in hospitals, and most of them are rubber products. There are also rubber products as accessories for medical equipment and instruments. Medical rubber products often have special requirements, such as non-toxicity, sterilization, physiological inertia, radiation resistance and so on. Butyl rubber of rubber towel has high biological inertia, chemical stability and slight water permeability. When used for processing rubber bottle stoppers, it can ensure the preservation of high moisture absorption and anti-commercial anticancer preparations. In recent years, silicone rubber has been widely used to manufacture medical products. For example, silicone rubber has made great progress in the manufacture of artificial organs and human tissue substitutes, and it has also been used to make drug capsules, which can slowly and continuously release drugs at appropriate positions in the body, which can not only improve the curative effect, but also be safer. (8) Rubber and commodity storage rubber are not only used for medical care of cattle, but also for storing fruits and vegetables. Since 1954, modified atmosphere technology has made great progress and is widely used in rubber film storage of fruits. Silicone rubber has excellent air permeability and a proper air permeability ratio with Coa and O2. The ratio of the two is 6: 1, which means that the diffusion speed of carbon dioxide through the silicone rubber window is 6 times faster than that of oxygen. It is about 200 times faster than carbon dioxide and oxygen passing through polyethylene plastic film. According to the difference of respiratory intensity and quantity of different fruits and vegetables, silicone rubber dumplings of various sizes are made and embedded in plastic film control, which can keep a proper amount of CO2 and O: in the bag and form a good gas storage environment, thus inhibiting the respiratory intensity of fruits and vegetables, delaying the metabolic rate, delaying the after-ripening process of fruits and vegetables, reducing water evaporation and preventing rot. Compared with the experiment of storing apples, the natural consumption of plastic wrap packaging for five months is below 0.7%, and the natural consumption of unused apples can reach 5.83%. For another example, Xihong was stored in modified atmosphere with silicone rubber film for one month, and all the fruits were green and good, with a weight loss of 3.6%. After being taken out, all the fruits could turn red and mature normally. Tomatoes that don't need modified atmosphere will turn red and mature within a week and can't be stored any more. (9) The root glue and all kinds of rubber balls, table tennis bat sponge rubber surfaces, swimming feet, toy rubber balls, fountain pens, erasers, rubber traps, rubber lines, rubber seals, rubber blankets, balloons, sponge rubber mats, etc. commonly used in cultural and educational sports activities are widely used in cultural and educational institutions, offices, design drawings, sports equipment, etc. (X) Rubber and daily necessities There are many rubber products serving us in our daily life, which are worn by urban and rural residents all over the world. It is a kind of rubber product with a large amount. Others, such as raincoats, hot water supplies, purple ribbons, children's toys, sponge cushions and latex impregnated products, all play a role in people's lives.
