Triethanolamine is a colorless, transparent and viscous liquid at room temperature, with a slight ammonia smell. It is hygroscopic and can absorb moisture and carbon dioxide in the air. Can be freely mixed with water and alcohol, soluble in chloroform, slightly soluble in benzene and ether. The pH of 0.1moI/L solution is 10.5. There is a danger of burning when exposed to high heat, open flame or contact with oxidants. Its aqueous solution is corrosive.
Application of triethanolamine in the construction industry;
It can not only be used to prepare steel and cement corrosion inhibitors, protect steel and cement, and protect metals from oxidation, but also It can be used as a drought strength agent for cement.
For example, using 5/1000th of triethanolamine and 5/1000 of salt (for cement) dissolved in water to prepare cement can shorten the cement hardening time and increase the early strength of the cement (the strength in two days can be Reaching 50% of the 28-day strength, and increasing the later strength of cement, it is easy to use and has outstanding effects.
In addition, it can also be prepared for reinforced concrete, steel bar rust inhibitors, etc.
