Water reducers are divided into three general types: conventional, mid-range and high-range admixtures. While the properties of water reducers within the “conventional” category are typically very similar, the chemistries used by different manufacturers vary. Within the mid- and high-range produ

Researches shows that

Commonly used liquid grinding agent before the main raw material for three isopropanolamine, triethanolamine and now have three can replace triethanolamine and isopropyl alcohol amine new grinding agent of raw materials, Chinese name is two ethanol isopropanolamine, English name Diethanolisopropanol

In the grinding process of cement materials, adding a small amount of external substances (gas, liquid or solid substances), can significantly improve the grinding efficiency or reduce energy consumption, and does not damage the performance of the cement of this chemical additive external substances

The cement grinding process is different, and the added grinding aids are also particular. For the closed-circuit grinding system and the open-circuit grinding system, the correct use of the grinding aid can be effectively achieved.

Triisopropanolamine is an amine separated from rectification after addition reaction of ammonia and propylene oxide. It can be widely used in daily chemical industry, fine chemical industry, petrochemical industry, etc. It is an important amine compound. TIPA is the core raw material of cement grind

Cement is an indispensable basic raw material in the construction of national infrastructure and economic development. However, with the increasing pollution of the environment, the production of cement is still in a high energy consumption industry.Portland mineral cement is widely used in the market.

The Triisopropanolamine,Diethanolisopropanolamine,Triethanolamine as cement grining aid could effective participate in hydration reaction with , C3A, C3S, C2S, and C4AF.

Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement grinding. It can significantly increase the output of cement platform, the strength of cement at various ages, and improve its fluidity. The cement grinding aid can greatly reduce the phenomenon of electrostatic adsorption ball formation formed during the grinding process, and can reduce the re-agglomeration tendency of the ultrafine particles formed during the grinding process. The cement grinding aid can also significantly improve the fluidity of the cement, improve the grinding effect of the mill and the powder selection efficiency of the classifier, thereby reducing the energy consumption of the grinding. The cement produced by the grinding aid has a lower tendency of compaction and coalescence, which is beneficial to the loading and unloading of the cement and can reduce the wall hanging phenomenon of the cement storage.

A grinding aid is a surfactant that can improve the grinding environment. The common grinding aid is to improve the grinding effect by improving the viscosity of the material in the mill, the dispersion of the particles and the flow state of the slurry. To a large extent, it solves the problems of powder consumption and energy consumption. The main purpose of the grinding aid is to reduce or terminate the aggregation of the particles, to improve the fineness of the cement and the specific surface area, or to grind to the same fineness, and to increase the productivity when adding the grinding aid. At the same time, the addition of the grinding aid adsorbs the surface of the cement particles, reduces the friction between the particles and the adhesion, so that the cement particles slide, and the fluidity thereof also becomes better, thereby improving the grinding efficiency and the cement performance.
