Diethanol monoisopropanolamine was produced in the 1990s and is a non-toxic, skin-irritating product that is less irritating to triethanolamine and environmentally friendly alkanamines. It is mainly used as a surfactant. In the fields of cement grinding aids, daily chemical products and fabric softe

Granulated blast furnace slag has high potential activity, but poor grindability. At present, the technology of cement grinding aids has been workable, but there are few systematic studies on granulated blast furnace slag grinding aids. In view of this, this article mainly studied nine kinds of aids such as triisopropanolamine, triethanolamine, glycerin, ethylene glycol, ethyl acetate, diethylene glycol, anhydrite, hemihydrate gypsum, and dihydrate gypsum.

In the cement industry, a large amount of energy is consumed in the grinding of raw materials and their clinker. Grinding process, cement particle surface free charge density increases, the solid surface free energy increase, coupled with the collision between particles

Effect of Triethanolamine and Triisopropanolamine on the Hydration Process of Slag Cement Triethanolamine and triisopropanolamine were used as grinding aids for slag cement. By measuring the granular properties, setting time, mortar strength, and chemically combined water content of cement, amounts of grinding aids were used to investigate the hydration process of slag cement. Influences, and the use of x-ray diffraction and scanning electron microscopy analysis of the slag cement hydration product phase composition and microstructure. The results show that both grinding aids can significantly increase the hydration rate of slag cement, make more hydration products in the cement slurry, and form a more compact structure. The effect of triisopropanolamine on slag cement is excellent. In triethanolamine.

Composite Portland cement additive formula: sodium acetate, purified water, triisopropanolamine, triethanolamine, ethylene glycol and polyethylene glycol; mixing and mixing of the components to obtain the cement additive; the cement additive obtained in the cement grinding When the process is added

Chemical admixtures are used in concrete for various purposes such as water reducing, plasticizing, air entraining, bonding, viscosity modifying, colouring, corrosion inhibiting, permeability reducing, accelerating or retarding the initial setting time, and shrinkage reducing. The use of chemical ad

World Consumer Rights Day is celebrated annually by consumer organizations worldwide. It commemorates the historic declaration on March 15, 1962 by John F．Kennedy, the former US President, of the basic Rights of consumers, which include: "the right to safety", "the right to be informed"

Slag cement has the advantages of low heat of hydration, high strength in the late stage, inhibition of alkali aggregate reaction and sulfate resistance. It has been applied in a large number of projects. In the produce process of slag cement, the slag is not easily grind than the clinker, If grinding two materil together can not reach their optimum active particle size, and separate grinding will cause a lot of energy consumption, so the grinding process used Grinding aids to reduce grinding energy consumption and improve cement performance.
