Application of inorganic silicon compound refractories for the development of silicon compound cementing refractories resistant to water and acid resistance due to the complex engineering conditions, there is acid water before and after the heating of the project, or in the heat of the role of acid medium, Inorganic Compound require refractory materials have heat resistance and acid resistance to water. Inorganic Compound The unheated water glass refractory specimens immersed in different types and concentrations of acid see table in water storage than in acid storage strength decreased, than in the air curing strength also decreased.
Because there is no reaction between the silicate and the acid in the water, silicic acid gel is no longer produced, but the soluble matter dissolved, the structure is not tight, Inorganic Compound the strength drops, conversely, the higher the acid concentration of refractory strength is higher, which shows that the role of acids and silicate strengthen, improve the strength.
The high-temperature performance of sodium silicate refractories, acid and water resistance and sodium silicate properties, sodium fluoride content, aggregate types, in the production should be strictly controlled. The modulus of sodium silicate is the High-temperature property of refractory. Inorganic Compound Acid and water resistance can have a significant impact, high modulus, with good acid resistance and high temperature performance modulus low will reduce these properties. Generally the choice of modulus is better.
At home and abroad, the application of inorganic silicon compounds in refractory materials has been reported, and new technologies and materials have been developed. Inorganic Compound It is suggested that the refractory materials suitable for various industrial production conditions should be developed to meet the needs of various industries.
There are two kinds of water in the cell, which are free water and combine water. The combination of water and other materials is an important component of cell structure, Inorganic Compound accounting for about 4.5%, free water exists in the form of free, is a good solvent for cells, can also directly participate in biological chemical reactions, but also transport nutrients and waste. In a word, all life activities of all kinds of organisms are inseparable from water.
Most of the inorganic salts in the cells exist in Ionic states, although their content is very small, but it has many important roles: some inorganic salts are important components of some complex compounds in cells, such as FE is the main component of hemoglobin, MG is the essential ingredient of chlorophyll molecule. ; Many inorganic salts are important for sustaining the life activities of cells and organisms, Inorganic Compound such as the presence of calcium ions in the blood too high to cause convulsions; it is also important to maintain the acid-base balance of cells.
