Stability and weatherability of magnesite fireproof door core
Editors:Sen You Yi  Time:2018-4-16

  Magnesite fireproof door core is a new generation of non flammable thermal insulation products. Mainly is the natural magnesium oxychloride inorganic environmental protection material, which is compounded by mechanical flow production. Magnesium oxychloride is a very high quality material. Its fire resistance is very good. It is loved by many consumers. It is a kind of product with very good performance. Magnesium chloride plates will also have many unknown advantages. When we work, we can choose the right products according to our needs.

1, air stability and weather resistance
  The magnesium oxychloride plate is an air hardening cementitious material. It can only continue to coagulate and harden in the air, which makes it have good air stability. When the magnesium oxychloride plate is solidified, the more dry the air is, the more stable it will be. The test shows that the compression and flexural strength of the magnesium oxychloride fireproof plate products increase with the age of the dry air, until the age of two years is still growing, and it is very stable.

2, low degree of low fever and low corrosion
  The pH value of slurry of magnesium oxychloride plate fluctuates between 8~9.5, which is close to neutral, and has little corrosive effect on glass fiber and wood fiber. It is known that GRC products are reinforced with glass fibers, and wood fibers are reinforced with sawdust, shavings, cotton stalks, bagasse, peanut shells, rice husks, corn heart powder, etc., while glass and wood fibers are both alkali resistant materials, extremely afraid of alkali corrosion, and they all lose strength under high alkali corrosion and to cementitious materials. The material loses its enhancement. Therefore, conventional cement can not be reinforced with glass fiber and wood fiber because of high alkali. Magnesia cement, however, has demonstrated its potential in the field of GRC and the field of fibrous products by virtue of its unique slight alkalinity.

3, light and low density
  The density of the magnesium oxychloride plate is generally only 70% of the ordinary portland cement products. The density of the products is generally 1600~1800 /m3, and the density of the cement is generally 2400~2500 /m3. So it has a very obvious low density.

  The effect of magnesium oxychloride plate is very high, the use of reasonable effect is very good, a lot of products in the tangled choice of what style of material, may try to choose the use of magnesium chloride plate. The magnesium oxychloride plate is very good in stability and weather resistance, and it is also a material of excellent quality. Use a great effect.
