Q:What is the main component of automobile sealant?

Among them, the room temperature curing type has one component and two components. It is widely used in buildings, squares, roads as caulking sealing materials, sealing and automobile manufacturing, installation of glass, electronic filling, submarines and the Rockets

Q:What is the function of the automobile exhaust lug?

The exhaust pipe is a part of the engine exhaust system, exhaust system includes an exhaust manifold, exhaust pipe and muffler, generally three school control engine emission of the catalytic converter is also installed in the exhaust system, exhaust pipe generally includes a front exhaust pipe and exhaust pipe.

Q:What are the tyres made of and what is the manufacturing process?

Refining process is the process of mixing carbon black, natural / synthetic rubber, oil, additives, accelerators and other raw materials, processing in the mixer, and producing the "glue". All raw materials must be tested before entering the mixer and can be used after being released. The weight of each mixer is about 250 kilograms. Each rubber component used in the tire is of a specific property. The composition of the rubber depends on the performance requirements of the tire. At the same time, the change of the composition of the rubber depends on the needs of the manufacturers and the market. These requirements mainly come from traction, driving performance, road conditions and the requirements of the tires themselves. All glue shall be tested before entering the next process - Preparation of plastic parts, and shall be released before proceeding to the next process.

Q:Where does the rubber from the car come from?

There is a tree called a rubber tree, a white liquid, that is the basic material of bananas. China is relatively small, and Asia is mostly produced in countries near the equator.

Q:Excuse me, is there a ground adhesive tape at the end of the tank truck? What's the use of it?

When the tanker starts, the oil is churned up in the car, which will rub against each other and produce static electricity. If the static electricity is saved, it may cause a fire or explosion on the tank car. In order to import the electrostatic into the earth and ensure the safety of the tanker, a conductive rubber strip is drawn from the oil tank at the rear of the vehicle, which can be left over to the road surface so as to ensure that the static electricity in the tank is imported into the ground.

Q:There is a smell of rubber and plastic in the inner room. What's wrong with it?

Smell the smell and the owners will pay more attention to it. First of all, should immediately stop fire, stop all open flames, a thorough examination of the oil circuit to determine whether the oil leak. Then you must repair as soon as possible.

Q:The new bicycle tires are why side rubber thorns?

Tread patterns are so important. Who invented them? There is no accurate answer to this question, but we only know that it generally appeared around 1892. The most primitive tread pattern is very simple, only some straight lines of flowers. But in the condition of the road surface, speed, load and other conditions change constantly, the tread pattern of the tire has become more and more complex and diverse after more than 100 years of development.

Q:What is the difference between asphalt damping sheet and butyl rubber?

Polycyclic aromatic hydrocarbons (PAHs) are a class of compounds composed of two or more aromatic rings, distributed and widely distributed in natural environment (two). Because most PAHs have carcinogenicity and teratogenicity, they have received extensive attention. Is a common, highly reactive, indirect carcinogen. 3, 4- benzopyrene released into the atmosphere, and always formed various types of atmospheric aerosol particles together in 8 microns of respirable dust particles, higher ratio of lung inhalation through respiratory tract, lungs, and even into the alveolar blood, leading to lung cancer and cardiovascular disease.

Q:Method for machining polyurethane rubber by lathe Too elastic

Use a knife or a knife, like a kitchen knife. The knife should be thin. Cut it directly with the blade. If the car is round, there is no way. Only the ordinary way.

Q:What is the ratio of carbon black in automobile tire rubber?

Carbon black is a reinforcing filler of important system, have an important impact on the physical and mechanical properties and processing technology of rubber, but for the influence of rubber heat resistance, oil resistance, corrosion resistance and other properties of the medium, far less than the rubber vulcanization system and protection system of large and direct. Because of this reason, the general formula personnel specific performance index of carbon black carbon black as a technical staff attention, often only pay attention to selecting a type of carbon black, without detailed investigation using specific indexes of carbon black, or by different kinds of carbon black and carbon black, and no machine and used to packing product requirements. Therefore, it is difficult to quantify the impact of specific physical and chemical indicators of carbon black.
