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 board and other insulating materials like long-term use will produce aging phenomenon. Compared with the general plate, the aging degree of insulation board is relatively severe, the aging speed is still relatively significant, the following small to give us an analysis of the long-term use of mica board after the aging of what are the reasons.

Mica board in the use or storage process, 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 failure rate of electrical equipment is significantly related to the application time of insulation materials, and the related curve is called the bath curve. Three regions in the curve.

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

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

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