The difference between magnesium oxychloride board and magnesium oxysulfate board

Nov 02, 2018

What is a magnesium sulphate plate: a refractory, light-weight, water-resistant, green, non-radiative high-performance sheet made of magnesium oxide, aqueous magnesium sulfate solution, modifier and various auxiliary materials through agitation, pressing, curing and other processes.

The difference between magnesium oxychloride board and magnesium oxysulfate board: magnesium oxychloride board does not absorb moisture compared with magnesium oxychloride board, does not return halogen, has high durability and strong adaptability to the environment. As we all know, magnesium oxychloride board will reduce the chemical stability energy with the increase of temperature and time, and it will easily cause moisture absorption and return to halogen; this potential is hidden by the moisture-reducing and halogen-changing variant, for the magnesite industry. It is undoubtedly a repetitive, superimposed endless disaster.

In the article of the 2013 annual conference of the industry, "The method of rooting magnesium cement to absorb moisture and return to halogen is not to use magnesium chloride", the author Wen Yuquan and Yan Meng screamed: "To cure the glass magnesium plate to absorb moisture and return to halogen, only magnesium chloride can be used." The engineer of Cao Yongmin of Shandong Building Materials Research Institute said: "If magnesium sulfate is used as a blending agent, there is no destructive halogen ion in the system, which can fundamentally eliminate the side effects caused by chloride ions, but the magnesium oxysulfide cement The mechanical properties are poor and can not meet the requirements of the product. Obviously, if the problem of poor mechanical properties of the magnesium sulphate plate is solved, the magnesium sulphate plate can be made and put into use."
