• Why we chose Polycarboxylic acid-based high-performance water-reducing agent (liquid)

  Polycarboxylic acid-based high-performance water-reducing agent (liquid) is the third-generation high-performance water-reducing agent developed after the general water-reducing agent represented by wood calcium and the superplasticizer represented by naphthalene series. The most advanced water-reducing agent with the highest cutting edge, the highest technological content, the best application prospect, and the best overall performance. PCE polycarboxylic high-performance water-reducing agent represents the most technologically advanced superplasticizer in the world today. Comparing with the performance of similar products at home and abroad, PCE polycarboxylate-based high performance water-reducer has reached the international advanced level in terms of technical performance and cost performance.

• The situation of Cement grinding aid raw material

  As the main raw materials for the production of cement grinding aids are mostly alcohol amine(Triisopropanolamine,Diethanolisopropanolamine 85%,Triethanolamine 85%), recently, due to the impact of international crude oil prices, the price of alcohol amines has also been rising all the way, and there has been a situation where demand exceeds supply. The manufacturers have to increase sales prices, causing some cement manufacturers to accept. In response to this situation in the market, a grinding aid production company in China has changed its thinking, researched and discussed programs, has gathered talented people, and invested heavily to strive to produce a cement grinding tool that is free from dependence on alcohol amines and high quality and low price. Agent. It is reported that this company has made unremitting efforts to find an organic substance that can replace alcohol amines in the waste oil and waste liquid from oil plants. This raw material is cheap and inexpensive. After o

• The role of surfactants

  Surfactants have become a class of flexible due to a series of physicochemical effects such as wetting or anti-sticking, emulsification or demulsification, foaming or defoaming, and solubilization, dispersion, washing, antisepsis, antistatic, and corresponding practical applications. , Wide range of fine chemical products. In addition to surfactants as detergents in daily life, other applications can cover almost all fine chemical fields.

• What is Fluorosurfactant

  The fluorosurfactant is a surfactant having a special property in which part or all of hydrogen in the hydrophobic group of the hydrocarbon surfactant is replaced by fluorine. Since its hydrophobic base is a perfluorinated or polyfluoroalkyl group, its surface tension is lower than that of hydrocarbons, and therefore the fluorocarbon hydrophobic base is subjected to a greater repulsive force in an aqueous solution, so the fluorosurfactant is water and organic. Solvents exhibit very high surface activity with very low levels of surface activity.

• Why we should use multifunctional cement grinding aids

  At present, there are about 200 companies that produce cement grinding aids in China . According to market survey statistics, the annual production of various grinding aids in China was approximately 1.5 million tons in 2014. Among them, the proportion of grinding aids that play a role in pure grinding and production lifting is relatively small, and various types of multifunctional grinding aids are used. Production accounts for more than 85% of the share. The multi-functional development of grinding aids （main TIPA,DEIPA）has become an urgent demand for users of cement companies. The important role of multifunctional grinding aids is shown in the following aspects:

• AEO 9 funtion in indusry detergent

  First, aeo-9 is a fatty alcohol polyoxyethylene ether, R-O-(CH2CH2O)nH (R=C12-18, n=15-16)), which is a natural fatty alcohol-ethylene oxide adduct. Non-ionic surfactants. Mainly used as emulsifiers for emulsions, creams, and shampoos. Excellent water solubility, can be used to make oil-in-water emulsions. It can also be used as an antistatic agent. Hydrophilic emulsifiers can enhance the solubility of certain substances in water and can be used as emulsifiers for the production of O/W emulsions.

• The difference between Tween 20 and Tween 80

  The difference between Tween 20 and Tween 80 Tween is also called Tween-type emulsifier. It is a condensate of Span (sorbitol fatty acid ester) and ethylene oxide. It is a kind of non-ionic detergent. Chemical name: polyoxyethylene sorbitan fatty acid ester, abbreviated polysorbate. Since the Span is an ester formed from sorbitol and different higher fatty acids, Twain is actually a series of products of the same type. There are 20, 40, 60, 80 kinds of products in general fine chemical stores or chemical reagent companies, depending on the Need to choose. Tween-60 is stearate; Tween-80 is oleate; Tween-20 is laurate, is polyoxyethylene sorbitan monolaurate and part of polyoxyethylene sorbitan monohydrate. A mixture of laurate.
