Cement enterprises generally divide the grinding aid into "enhanced" and "stimulation", how to choose? It is generally believed that to increase the intensity of the choice of "enhanced" grinding aid, to increase production or save electricity to choose "increase production" of the grinding aid.

In the past five years, the continuous improvement of the comprehensive performance requirements of the roof has promoted the innovative development of roof design. The roofing association, as always, has worked with its members to seek innovative solutions to the application of concrete tiles

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:

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 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.

Domestic most of the original road pavement structure of cement concrete panel, this kind of structure joints and cracks easily, eventually lead to diseases such as fault sets, escapes, pavement damage, and influence the comfort of driving.

What are Admixtures ?They are natural or manufactured chemicals which are added to the concrete before or during mixing.Commonly used are Air-entraining agents, Water reducers, Water-reducing retarders and Accelerators.Why are they Used ?They are used to give special properties to fresh or hardened

polyols, propylene glycols and propylene glycol ethers are three main derivatives markets of polypropylene oxide (PO)major part of propylene oxide is produced by chlorohydrin propylene oxide (CHPO) process; other technologies include propylene oxide/styrene monomer (POSM), propylene oxide tertiary b

Alcohol Ethoxylates (AE or AEO) are a major class of non-ionic surfactants.Fatty Alcohol Ethoxylates are produced by reacting natural fatty alcohol with Ethylene Oxide (EO). Regarding chemical structure of alcohol ethoxylate, the more the ethylene oxide groups added to the fatty alcohol, the higher

The agency has investigated the recent trend of ethylene oxide in nine production companies and 11 downstream users. Three of them think the price of ethylene oxide will fall this week, accounting for about 15%.There are 12 users who believe that the price of ethylene oxide will be stable this week,
