Characteristics and applications of mica tubes

On the basis of ensuring the quality of the existing mica tubes, we will carry out research on the effects of mica scale particle size gradation, mica tube type and mica content on the electrical and mechanical functions of mica insulation, further improve the functions of mica tubes, aim at the international advanced level, develop thin specification, thick specification, high dielectric strength, high tensile strength, mixed copy, high permeability and aromatic polyphthalamide mica tubes, etc., so as to make new contributions to the development of China's electrical industry.

China's mica tube production enterprises and production lines, although the production capacity and output value of mica tube is large, but the quality and stability of the product is poor. The main reason is that the mica tube production process control precision is low and inefficient, for example, the mica tube thickness requirements for 80um, but China's production of mica tube products thickness fluctuations of nearly 20%, directly affecting its electrical insulation function and high temperature resistance function.

In addition to other structural factors of mica tube manufacturing, the main reason for this situation is the low degree of automation of our mica tube production line, many important control processes are guided by manual experience, so that not only the control is not accurate, but also low efficiency. Pulp concentration and paper thickness are closely related, therefore, to improve the quality and production value of mica tubes, the main content of future research is based on the present basis of the transformation and updating of production equipment, to replace the manual reading operation with pulp concentration and paper thickness online test to achieve paper thickness and pulp concentration.
