At present, the main filling materials of electric heating pipes are quartz sand and alumina. Why is cable-grade magnesia powder the main filling material? Next, I will explain it to you in detail. Low iron magnesia


Mainly because it is an electrical insulator, a good conductor of heat, high safety, cheap, easy to buy, and has a large storage capacity, so cable-grade magnesium oxide powder has been widely used in electric heating pipes for a long time.


Magnesium oxide needs to be melted at a temperature of 2800 degrees after refining, so that the crystal is completely stabilized and cooled into a block. Due to the influence of cohesion, the purity of the middle part is relatively high (specific gravity 3.58-3.6). This block is crushed by an iron hammer and then sent out. After the iron filings are mixed with the mesh, the magnesium oxide powder used as the filling material is now used, and the mesh specification used now is 40-325 mesh.


What is Cable Grade Magnesium Oxide Powder? What are the categories and features?


Cable-grade magnesia powder refers to fused crystalline magnesia blocks that are crushed and matched with different particle sizes (mesh) in a certain proportion, and directly or modified to be used in tubular electric heating elements as an insulating medium for heat conduction at high temperatures.


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 sieve after Z. 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 ℃.
