The influence of mica paper on the quality of अभ्रक टेप

The quality of mica paper itself also directly affects the application performance of mica. The mica paper used to produce mica tape must have good permeability, higher tensile strength and better compactness. In addition, the thickness of the mica paper must also be uniform. Since the bonding force between the small mica flakes in the mica paper is very small, the production of mica tape is to use the adhesive of glue to improve the adhesion between the small mica flakes, so when the penetration force of the mica paper is too poor When the glue is impermeable, the mica tape will be stratified, and its quality will not meet the requirements.

In the process of producing mica tape, the mica paper itself has to receive a certain tensile force. When the tensile strength is too low, the mica paper will crack or even break, which greatly reduces the fire resistance and insulation of the mica tape.

Generally speaking, when the thickness of the mica paper is constant, the denser the mica paper, the better the fire resistance and insulation of the mica tape produced. When the thickness of the mica paper is not uniform, the fire resistance and insulation of the mica tape are correspondingly poor if the thickness is lower than the standard thickness; the glue is not easy to soak in the places higher than the standard thickness, even if it is soaked, the mica tape is not easy Drying, because for a certain thickness of mica paper, its heating temperature and heating time are fixed during the production process, which causes local delamination of the mica tape and affects the product quality of the mica tape.
