Features: Contains two hydroxyl groups and one amino group. Hydroxyl reduces the vapor pressure, increases the solubility, is conducive to the absorption of acid gas, and can increase the concentration, reduce circulation, and reduce energy consumption. The presence of the methyl group in the amino group reduces the alkalinity and activity of the amino group and reduces the CO2 absorption rate.

TDI is the abbreviation of toluene diisocyanate. TDI is a polycyanate widely used in industrial production. It is a polyurethane material and an important basic material. Mainly used to make flexible polyurethane foam, polyurethane elastomer, coatings, adhesives, etc.
TDI (toluene diisocyanate) is one of the commonly used polyisocyanate, and polyisocyanate is an important base material of polyurethane (PU). The TDI commonly used in the polyurethane industry is a mixture of 2,4-TDI and 2,6-TDI isomers, including three commonly used grades.
Since the use of sodium nitrite in the bleach is due to its ability to form sulfur dioxide, sulfur dioxide has strong oxidation resistance, and color oxidation can be oxidized.
The shape of sodium persulfate is milky white crystalline powder, which is soluble in water, and can accelerate the dissolution in wet humidity and high temperature; it can be dissolved by ethanol and silver ions, and the solubility in water at 20℃ is 549g/L; sodium persulfate is also deliquescent , In humid air and high temperature can accelerate the dissolution of sodium persulfate, release oxygen and become sodium pyrosulfate.

Hydrogen peroxide is also known as hydrogen peroxide, and its chemical formula is H2O2. Its appearance is a light blue viscous liquid, which can be mixed with water at will. It is an oxide and reducing agent, but the effect of hydrogen peroxide in different situations There are also certain differences. Today, let us talk about the actual effects of hydrogen peroxide in different uses.
About 78% of nitrogen gas can be used to make ammonia, nitric acid, nitrate, cyanide, etc. When making explosives; filling high-temperature thermometers and incandescent bulbs; forming inert material preservation materials for drying boxes or glove bags.
It is necessary to reduce the harm of human beings. The best way is scientific application. Carbon dioxide actually has two sides. On the one hand, a greenhouse effect will be generated; on the other hand, it will benefit humanity, such as use as plant gas and fruit and vegetable prevention.
The appearance of potassium hydroxide is white lumps or powder, with strong corrosiveness and strong alkalinity. When potassium hydroxide is exposed to gas, it is easily wetted by moisture in the air, digesting and absorbing carbon dioxide to become potassium carbonate.
