  The rational use of magnesium oxychloride plate is very necessary. Many places in the life will choose to use the magnesium oxychloride plate in the process of processing and production. The meaning of the magnesium oxychloride plate itself is very high. In fact, the magnesium oxychloride plate itself is very characteristic, and the benefits of different magnesium oxychloride plates are different when they are used. Yes.

  What is the characteristic of the magnesium oxychloride plate

  1.The magnesium oxychloride plate is different from ordinary portland cement in setting and curing mechanism. It is an air hardening cementitious material and does not harden in water.

  2, multiple components The magnesium oxychloride plate is a multi component component. The single component light burned powder has no strength after being hardened by water. Its main components are light burned powder and magnesium chlorate. Other components include water, modifier and filler.

  3. High strength After adding modified magnesium oxychloride plate, the compressive strength can reach 60MPa, and the flexural strength can reach 9MPa.

  4, 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.

  5, 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.

  6, 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.

  Magnesium oxychloride plate will have many demands and use for today's society. Different magnesium oxychloride plates have different products and meanings. The magnesium oxychloride plate itself is also very high quality.
