1、 Performance and characteristics
This product is a kind of compound powder grinding aid dispersant developed by our company on the basis of the type and performance of original dispersant and according to the grinding situation of inorganic pigment grinding industry.
This product is a new type of dispersant synthesized by compound coupling agent and refined polyol. It integrates grinding aid, dispersion and surface modification. It is mainly used for dry superfine grinding of inorganic pigments such as calcium carbonate, porcelain clay, talcum powder and titanium dioxide. It is suitable for vertical mill, horizontal ball mill, ring roller mill and other dry superfine grinding equipment, especially when the powder fineness is more than 1250 mesh Because of its strong dispersibility and good fluidity, adding in the ultra-fine grinding process can not only shorten the grinding time, improve production efficiency, but also obtain uniform particle size distribution, so as to achieve the ideal dispersion effect. The powder produced by using this product has good gloss and oil absorption value Low.
This product has good heat resistance, mutual solubility, efficient wetting dispersion, and non-toxic, non corrosive, no special smell.

4、 How to use it
In the process of ultra-fine grinding, this product can be added directly with a metering pump without dilution. The amount of this product is 0.1-0.2% of the absolute dry pigment. If the grinding process has special requirements, it can also be added after dilution according to a certain proportion. The dilution amount depends on the specific situation of the manufacturer.
5、 Packaging
1. The dispersant is packed in plastic drum with net weight of 250kg. Other packages can also be used according to the needs of users.
2. The storage temperature is 5 ~ 30 ℃, and the shelf life is 12 months.
