Talking about the difference between glass magnesium plate and magnesium sulfate plate

1. Magnesium oxide (produced in Sichuan, Northeast, Shandong)

2, magnesium chloride (halogen or halogen tablets)

Other added materials:

1, modifier, accelerator / retarder,

2, sawdust / fly ash / rice husk powder

3. Expanded perlite (a sanding layer for sanding panels)

Description of various materials: usually a magnesium chloride solution with a Baume degree of 26 and a magnesium oxide material with a 60% activity.

The final material is composed of 5Mgo 1Mgcl.8H2O crystals and additives such as sawdust.

At home and abroad, it is widely used in the most common fireproof panels, fireproof decorative panels, fire door panels and other applications. Because many details need to be controlled, many manufacturers fail to meet strict standards, resulting in a certain moisture absorption and back-halogenation phenomenon. Thereby corroding steel bars and iron gate steel doors.

Second, the magnesium sulfate plate has risen in recent years. Its biggest advantage is that it does not absorb moisture and return to halogen, and there are many sources of magnesium sulfate as materials, including the reuse of industrial waste acid. The main raw materials for magnesium sulphate plates are:

1. Magnesium oxide (ibid.),

2. Magnesium sulfate (preparation of industrial waste acid and magnesium oxide, coastal chemical by-product, pure sulfuric acid and magnesium oxide)

Other added materials:

1, modifier, accelerator / retarder,

2, sawdust / fly ash

3. Expanded perlite (a sanding layer for sanding panels)

The magnesium sulfate plate is usually selected from a magnesium sulfate solution having a Baume degree of 28 and an active 85% magnesium oxide;

Third, the comparison of glass magnesium plate and magnesium sulfate plate:

The main raw materials used in magnesium sulfate sheet are magnesia and magnesium sulfate. The application direction is the area where the original glass magnesium plate is restricted. The magnesium sulfate plate overcomes the problem of moisture absorption and anti-halogenation of the original glass magnesium plate and easy warpage. However, at the same time, the magnesium sulfate sheet produced by the existing manufacturers has the characteristics of poor strength and poor water resistance, and is also a product to be improved and improved in technology.
