What are the processing techniques for aluminum silicate ceramic insulation cotton?
According to its processing technology, it can be divided into blow blown cotton and spun silk cotton.
They are produced by calcining coal gangue, charred gemstones, decomposed materials, and then melting at high temperatures,
The process of spinning or blowing fibers into fibers is then carried out, and the bulk fibers are then formed into a certain amount through equipment
Thick cotton germ.
Due to the high brittleness of high aluminum materials, only the spraying process is used; Zirconium aluminum cotton blankets only have a spinning process; Relatively speaking
The production capacity of the spinning process is higher.
There are two types of production and molding processes for aluminum silicate ceramic fibers, one is the blowing process, and the other is the spinning process. What are the differences and development trends between these two processes?
history
From the perspective of production history, the earliest production process was the injection molding process, but the production capacity of a single line was relatively low, with an annual output of usually 1000 to 1500 tons. In order to improve production compliance, we continuously explore and discuss new production processes for aluminum silicate ceramic fibers, and later understand the more advanced spinning production process. The production capability of a single production line using spinning process is 2-4 times that of spinning process. The annual production capacity of the single line of the spinning process reaches 6000 tons.
application
The spinning process of aluminum silicate ceramic fiber cotton has been recognized by the vast majority of industry manufacturers and customers. In the past 10 years, almost all new aluminum silicate ceramic fiber production lines in China have chosen the spinning process. Blown aluminosilicate ceramic fiber cotton also has its unique application. If it is necessary to break the fiber into secondary products (such as making vacuum forming products), the blown fiber is more likely to be confused with other materials due to its fine fiber, so it is more popular.

Development Trends
From the perspective of development prospects, the total production volume of aluminum silicate ceramic fibers in China will continue to improve, and new production lines will still rely mainly on wire spinning production technology. Relatively speaking, the production scale and proportion of blown aluminum silicate ceramic fiber cotton in the total market will gradually decrease. The blown cotton production process is more suitable for enterprises with smaller production scales, especially those with smaller initial investment funds. The competition in the Chinese market for wire spinning production technology will also become increasingly fierce, which is definitely a merit for consumers, as they can enjoy more and better products with less money. This is a good thing for the development of related properties in China’s thermal energy application, especially for energy conservation and consumption reduction in industrial production processes.
The aluminum silicate ceramic fibers used in spinning and blowing processes have their own advantages. Customers need to choose their strengths and avoid their weaknesses based on practical applications in order to achieve better results. At present, spinning blankets are more suitable for applications than blowing blankets.
