For cars, people now pay more attention to space, preventive facilities, noise, heat insulation and other feelings during driving or safety in the event of an accident. Ceramic fiber products commonly used in the field of automobile manufacturing mainly include ceramic fiber blankets, ceramic fiber modules, and ceramic fiber paper. The following is a brief introduction to the ceramic fiber products used in the automobile manufacturing stage and different parts of the automobile.
01
The modification of automobile metal parts or the need to shape and eliminate the stress of the automobile body structure requires the use of a heat treatment furnace, such as a trolley-type heat treatment furnace or a hanging heat treatment line. At this stage, ceramic fiber modules and blankets need to be used as the lining of the metal parts heat treatment furnace.
02
Hood car sound insulation cotton, use ceramic fiber paper or thin ceramic fiber blanket to reduce the noise entering the cab. The noise of the hood running will increase with the increase of the speed, the increase of power, the increase of a lot of noise such as the engine roar, and it will enter the cockpit through various media, and lay a certain amount of engine on the hood. Insulation cotton can effectively reduce the transmission of noise generated by engine operation through the air channel. The sound insulation cotton on the upper and lower hood covers of the engine can also absorb part of the noise. The exhaust pipe is part of the engine exhaust system. The system mainly includes exhaust manifold, exhaust pipe and muffler. Generally, a one-way catalyst for controlling the emission of pollutants from the engine is also installed in the exhaust system. The exhaust pipe generally includes front exhaust pipe and rear exhaust tube.
03
The inner layer of the door panel is made of ceramic fiber paper or thin ceramic fiber blanket. In almost all car models, the area covered by the four doors is very large, and its coverage area is second only to the roof and chassis. It will come into direct contact with the air during driving. In addition to designers designing a certain rounded shape for the door panel to reduce the noise caused by wind resistance, car manufacturers also know that as long as there is more sound insulation inside the door panel The large area of cotton covered can also effectively absorb this kind of wind noise. The interiors of various models that were disassembled by the refitting shop were found only on the cars with higher prices on the market. This kind of sound insulation cotton appears on the inner layer of the door panel material.
