Glycerol is a colorless, viscous, hygroscopic, sweet-tasting trihydric alcohol. It is also called glycerin or glycerine, with the
term glycerol being preferred as the pure chemical form and the term glycerin(e) being primarily used when the compound is used commercially in various grades.
Magnesite, or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg2+ ions and O2 ions held together by ionic bonding. Magnesium hydroxide forms in the presence of water (MgO + H2O â?? Mg(OH)2), but it can be reversed by heating it to separate moisture.
The specification of MgO can be 50%, 55%,60%, 80%, 85%, 90%, 95%. It can be customized.

Sodium bicarbonate can be used in the production of acid base fire extinguisher and foam fire extinguisher, in the rubber industry sodium bicarbonate can be used in rubber, sponge production. Sodium bicarbonate can be used as a flux for casting steel ingot in metallurgical industry. In the machinery industry, sodium bicarbonate can be used as a casting steel (foundry) sand molding aid. In the printing and dyeing industry, sodium bicarbonate can be used as dyeing printing fixing agent, acid-base buffering agent, fabric dyeing and finishing rear treatment agent; Baking soda is added to dyeing to prevent the yarn from producing colored flowers. It can also be used as a detergent for wool.
In food processing, sodium bicarbonate is one of the most widely used osteoporosis agent, used in the production of biscuits, bread, etc., but after the action will remain sodium carbonate, too much use will make food alkalinity is too large and lead to bad flavor, yellow brown color. Is the producer of carbon dioxide in soda drinks; It can be combined with alum to form alkaline baking powder, and can also be combined with soda ash to form civil stone base. It can also be used as a butter preservative. In vegetable processing can be used as fruit and vegetable color agent. Adding about 0.1%~0.2% sodium bicarbonate when washing fruits and vegetables can make the green stability. When sodium bicarbonate is used as a treatment agent for fruits and vegetables, it can increase the pH value of fruits and vegetables, improve the water holding capacity of proteins, promote the softening of food tissue cells, and make astringent ingredients dissolve out. In addition to sheep milk to mutton, the use of 0.001%~0.002%.
Sodium bicarbonate can be used for agricultural seed soaking, but also can make up for the shortage of lysine content in feed, sodium bicarbonate dissolved in a small amount of water or mixed into concentrate for cattle feeding (add appropriate amount), can promote the growth of cattle, but also can significantly improve the milk yield of cows.
Sodium bicarbonate can be used as a pharmaceutical raw material, used in the treatment of excessive stomach acid, metabolic acidosis, also can alkalize urine to prevent uric acid kidney stones. It can also reduce the renal toxicity of sulfonamide drugs, prevent hemoglobin deposition in renal tubules during acute hemolysis, and treat the symptoms caused by excessive stomach acid. Intravenous drip has non-specific therapeutic effect on barbiturates, salicylic acids and methanol poisoning. However, it is forbidden to be used for gastric lavage in case of swallowing strong acid poisoning, with large amounts of injection, renal insufficiency or long-term application, arrhythmia, muscle spasm, pain, abnormal fatigue and weakness, slow breathing, bad oral odor, frequent urination, urgency of urination, persistent headache, loss of appetite, nausea, vomiting, etc.
