How to check whether Liaoning cable grade magnesium oxide powder has expired?

Regarding the question of whether magnesium oxide has expired, how to check whether the cable grade magnesium oxide powder has expired? , the price of electrical grade magnesium oxide powder let Xiaobian take you to find out!

The cable-grade magnesium oxide powder is initially checked. Under normal circumstances, the magnesium oxide should be a white powder. If the magnesium oxide changes suddenly, the complexion will change. In addition, the whiteness of the magnesium oxide is low if the phenomenon of the magnesium oxide is reduced. Obvious changes (clumps, etc.) can be observed, the nature is not uniform, and it is usually not considered to be used.

Then it is to check the storage conditions of magnesium oxide: if the moisture-proof work is not done during storage or transportation, it may cause magnesium oxide to denature and lose its use value. In normal work, the following routes can be used to build magnesium oxide containment Water absorption and transformation. 1. Cover with plastic film and lay plastic film on the ground. If you don’t want to change the bag and change the packaging, you can choose this step-by-step moisture-proof;

Production process of cable grade magnesium oxide powder

Electrical grade magnesium oxide powder price

Use 98 high-quality low-iron fused magnesia or 98 large crystal; magnesia has high refractory insulation properties. It can be transformed into crystals after high temperature burning above 1000 °C, and dead-burned magnesia or sintered magnesia when it rises above 1500 °C .

First, it needs to be broken, and then iron removal is carried out for many times; magnesia has high refractory insulation properties. It can be transformed into crystals after high temperature burning above 1000 °C, and it will become dead burned magnesia or sintered magnesia when it rises above 1500 °C.

A variety of additives are added, and the diluent is neutralized. Magnesium oxide has high refractory insulation properties. It can be transformed into crystals after high temperature burning above 1000 ℃, and it can become dead burned magnesia or sintered magnesia when it rises above 1500 ℃.

Then mix and stir, and finally sieve. Liaoning cable-grade magnesium oxide powder has high fire resistance and insulation properties. It can be transformed into crystals after high temperature burning above 1000 ℃, and it can become dead burned magnesia or sintered magnesia when it rises above 1500 ℃.
