What are the causes of aging of mica board after long-term use?

Mica has many physical and chemical properties, such as high temperature resistance, heat insulation, toughness and other characteristics, so its processed products mica plate also has many high-quality characteristics. Mica plates are also used as insulating materials for electric epoxy processing equipment. Mica plates made of mica are not only used in electric insulation, but also widely used in building materials, plastics, rubber and other chemical industries.

Mica boards, like other insulating materials, are subject to aging after long-term use. Compared with the general plate, the aging degree of insulation board is relatively severe, the aging speed is still relatively significant, the following Xiaobian to give us an analysis of the mica board after long-term use of the aging causes are what.

Mica board in the process of use or storage, its performance over time irreversible deterioration.

The reliability of the operation of electrical equipment is largely determined by the aging characteristics of the insulation material.

According to statistics, the error rate of electrical equipment has a clear relationship with the use time of insulation materials, and the related curve is called the bath curve. Three regions in the curve.

1. the pre-failure zone of epoxy processed parts, largely due to defects in material texture or subsequent manufacturing processes.

2. the random failure zone, which is largely caused by the anomalous conditions of the epoxy processed parts in operation.

3, for the failure zone caused by aging, the error epoxy processing parts rate increases with the increase in use time.
