The famous cement grinding aid manufaucer in the world

The famous brands in the international market include: American "Grace", Swiss "Sika", American "Ship", German Basf Company, British Foc Company, Italian Mi Company and so on. Most foreign patents for cement grinding aids are liquid products. Because the liquid product is easy to use, it only needs to add a storage tank and a liquid metering pump, and it can be added smoothly without complicated and heavy equipment. Among these, there are about 10 patents for cement grinding aids in the United States, which involve polymer synthesis techniques.


Foreign cement grinding aid products, most of the manufacturers also a few models, the technology is relatively mature, and its formulations are also basically fixed, do not need to change the formula often in order to adapt to changes in cement and seasons, as the concrete admixture products It is a single or composite product such as amines(Diethanolisopropanolamine,Triethanolamine,Triisopropanolamine),polyols, and acetates.

Due to the low content of these products, liquid cement grinding aid   is convenient, the grinding efficiency of the mill is increased by 10% to 20%, electricity consumption per unit of time is saved, the fluidity of the cement powder is improved, and it is advantageous for bulk transportation and storage. Therefore, it is used in foreign cement plants. Use is very common. Because of the internationalization of their products, these companies also meet the US ASTMC465 standard. Some or all of the replacements for triethanolamine have been made in the US patent in 2007.
