Use:
Triethanolamine is one of basic chemical raw materials, used in the cosmetics industry acid-base neutralization agent, emulsifier; cement in the process of grinding agent, concrete construction in the early strength agent; can be synthesized nitrogen Chuan three acetic acid; used in metal cutting, cooling, anti rust in metal processing; also used in electronics, ink and other industries; used as vulcanization activity agent non carbon black reinforced rubber in rubber processing, can also play a role in dispersing agent and water repellent; skin wound healing agent (biafine trolamine cream) of the main ingredients; and it is also one of the chemical raw materials of chemical weapons.
Packaging: tank, cold rolled steel (net weight 220 kg / barrel), irrigation water can also according to customer requirements.
Matters needing attention:
Decoration should avoid collision, prevent leakage; store in a dry, well ventilated place, avoid moisture.
