The quality of anti static plastic sheet itself also directly affects the application performance of mica, mica tape mica paper to have a good permeability, high tensile strength and good density, in addition, 6 thick thickness of the mother paper should be uniform The As the mica paper in the small mica between the adhesion force is very small, the production of mica plate is a glue with glue to improve the adhesion between the small mica, so when the mica paper penetration is poor In the production of mica plate process, the mica paper itself to receive a certain tension, when the tensile strength is too low, the mica paper (mica paper), the mica paper is not enough, the mantle board will be layered, the quality does not meet the requirements; It is necessary to crack, or even break, so that the mica board fire, insulation greatly reduced. In general, when the pe mica tape thickness is certain, the more dense mica paper, the production of mica board fire, the better insulation. When the mica paper thickness is not uniform, less than the standard thickness of the place, the mica plate fire resistance, insulation corresponding to worse; higher than the standard thickness of the place, glue is not easy to soak, even if soaked, mica tape is not easy Dry, because for a certain thickness of mica paper, in the production process of its heating temperature and heating time is fixed, which resulted in the mica board local stratification, affecting the mica plate product quality;
