        Can biosoluble ceramic fiber cloth be sintered ?

        First of all, the answer: Bio soluble fiber cloth can certainly be sintered. 

        What is biological soluble fiber cloth? This has been explained in other learning materials of fepford. It is inorganic fiber based on CaO + MgO + SiO2, which is made by special smelting and spinning. According to EU regulation 67 / 548 nota Q, it does not belong to any carcinogen classification. This is very important, and it is also an important reason why the biological soluble ceramic fiber can be based on, and it is also the primary reason why the biological soluble ceramic fiber gradually replaces the ceramic fiber. 

        Since there is the word "ceramic fiber" in the name, it has a lot in common with ceramic fiber in terms of various physical properties. For example, the current technology can only produce short fibers, but cannot make long fibers. For example, it is brittle and easy to break. For example, a single fiber is slippery, the friction coefficient is low, and it is difficult to entangle with each other like cotton fiber. This determines that the various product forms of soluble ceramic fiber are almost the same as those of ceramic fiber: fiber, blanket, felt, paper, cloth, belt, rope, etc. It is inevitable to learn from each other. 

        Therefore, the basis of biological soluble fiber textiles: the textile method of biological soluble fiber yarn is almost the same as that of ceramic fiber yarn: viscose is used to mix carding, glass fiber is used as the core material for spinning, and stainless steel wire (including 304, 310, 316 and other stainless steel wires) can be added to strengthen the plied yarn before weaving and weaving Rope and other processes. 

        So the bio soluble ceramic fiber cloth produced in this way also contains a part of organic fiber like the ceramic fiber cloth. When using this part of organic fiber, it will carbonize and smoke due to high temperature heating. Sometimes, because the heating speed is too fast, there will be open fire for a period of time, which will damage the strength of the bio soluble ceramic fiber. This puts forward the requirements for fepffer: sintering treatment of soluble fiber cloth, also known as calcination treatment, heating at a lower temperature for a long time, carbonizing and burning the organic fiber and a small amount of wetting agent in the biological soluble ceramic fiber cloth, so that the biological soluble ceramic fiber cloth becomes almost 100% inorganic component, which is easy to be used by customers It will not produce smoke and short-time open fire. This is the bio soluble ceramic fiber sintered cloth (calcined cloth). 

        Of course, fepford can also treat the soluble ceramic fiber belt in the same way, and turn it into soluble ceramic fiber sintered belt (calcined belt).
