Where Do The Raw Materials For Carbon Fiber Cloth Processing Come From?

We all know that polyacrylonitrile is polymerized by acrylonitrile, and some catalysts need to be added during the polymerization of acrylonitrile. The raw materials are poured into water to allow them to polymerize in water. Polyacrylonitrile polymer is insoluble in water and precipitates. Put the polyacrylonitrile water filter. The polymerization process is an exothermic process at the same time, so you must adjust the slow rate of the raw materials into the water so that this process may be eased, cooling, and also need to prevent the economy from overheating. This process is difficult to control. The water has various polymerized monomers and sediments, and there may be some uneven distribution of raw materials in the reaction vessel, resulting in polyacrylonitrile not meeting the required standards. This is the influencing factor of raw materials, and the reaction mechanism of the system still needs more research.

The fibrous carbon material of the carbon fiber cloth requires the use of coking containing a carbon atom chain polymer. There are three commonly used carbonized polymers: cellulose (rayon), polyacrylonitrile (PAN), pitch (pitch), and today it is polyacrylonitrile. If the thread is uneven and contains many impurities or defects, these defects will be transferred to the carbon fiber, so if you want to create a good carbon fiber cloth, you must have a good raw yarn.

How does the original carbon fiber cloth come from? It is spun with polyacrylonitrile. Polyacrylonitrile powder, polyacrylonitrile is first dissolved in a solvent, for reasons of confidentiality, I will not tell you this solvent dimethyl sulfoxide. Polymalononitrile is soluble in solvents, but insoluble in water, but this solution can be infinitely miscible with water. We spray the mixture of polyacrylonitrile and solvent similar to a shower spinneret, spray it into the solvent, water-soluble liquid, because polyacrylonitrile is insoluble in water, and it is a precursor of polyacrylonitrile that will be solidified into roots when encountering water. The line is very thick, while the solvent is dispersed in the chain, we can spread the solution through the n-layer. In this solution, the concentration is gradually reduced, which is conducive to the spread of the solvent. For example, after spreading, the original thread will enter the water stage. This time it will be pulled away by the application. The original thread will be slowly under the action of traction, and finally pass through the densification and silk. In order to prevent the adhesion between the fiber and the fiber, the sizing agent is also needed in the middle. This is the whole process of raw silk production. If polyacrylonitrile uses bad raw materials or is uneven, the raw silk spinning process is bound to have big defects.

Knowing the choice of carbon fiber cloth raw materials, I believe that our consumers will have a certain reference when buying carbon fiber cloth. We must choose high-quality carbon fiber cloth processed with high-quality raw materials. Only in this way can we be better. Strengthen our construction project!
