The magnesite cement used in the production of Mgo Fireproof Board is an inorganic cementing material. One of its characteristics is the appropriate temperature, humidity and hardening time after molding to make it fully chemically react to give the product excellent physics and mechanics. And durability. Therefore, the maintenance process parameters must be installed.
The main reason for the deformation of the Mgo Fireproof Board is its poor stability. Such products generally have a large format, a small thickness, and a large deformation value, which affects the construction quality of the project. This kind of malaise that appears in the project is the drawing seam of the board splicing and the unevenness on the large surface. There are many reasons for the deformation of the Mgo Fireproof Board. According to the investigation, the main reason is poor maintenance during production and insufficient hardening.
After the product is formed, it is placed in an environment with appropriate temperature, humidity and sufficient curing time, so that it can fully undergo a hardening reaction in this environment, and absorb free magnesium oxide and free water as much as possible in this hardening reaction. As much free water as possible is absorbed into the hardened material to become solid crystal water, which makes the product dry and reduces the shrinkage of the product. After this process, the volume stability of the product is in a good state, avoiding deformation during reuse. On the contrary, if the above hardening process is not performed well, the amount of hardened products produced in the product is insufficient, and free magnesium oxide and magnesium chloride are present in large quantities. Once the board is in use with proper temperature and humidity, the internal chemical reaction of the board will restart again. , There will be a great expansion internal force.
Zhangjiagang Leader New Construction Materia Co, Ltd, our factory will cure the Mgo Fireproof Board for 2 weeks after the production is completed, and control the moisture content at about 8% to be able to cut and pack without deformation.
