Which kind of mill is used to process the bicarbonate powder in the paint

Lacquer using painting process coated on the surface of the object after the formation of tough and continuous film, the raw materials used include grease, resin, filler, pigment, additives, etc., of which the filler is used in the bicarbonate of calcium, bicarbonate of calcium powder in the paint has a very big role.

Calcium bicarbonate is an important raw material in industry, according to the different fineness of calcium bicarbonate its role is also very different, now China's high fineness of calcium carbonate available in a much wider range, not only used as an additive, but also can be used as a filler, in the architectural coatings and paints is a huge amount of dosage.

Heavy calcium powder can be processed by calcium carbonate mill, generally calcium carbonate-rich ores such as limestone, calcite, dolomite, etc. According to the different fineness of the application, you can use high-pressure mill to process calcium powder below 400 mesh, use ultra-fine mill to process calcium powder in the range of 400-1500 mesh, and above 1500 you need an ultra-fine powder mill.

In the top coat due to the addition of calcium carbonate, it can be made into flat paint and semi-gloss paint. It can be used in large quantities in cases where light is needed, such as in architectural coatings. In the antirust paint system, adding calcium carbonate, because it can be hydrolyzed to generate calcium hydroxide, so as to increase the adhesion to the substrate, calcium carbonate can also absorb acidic medium, which is conducive to the rust prevention of the paint, so the antirust paint is also a large number of calcium carbonate to fill.

Heavy calcium carbonate oil absorption is relatively low, in the emulsion paint on the emulsion needs low, not only to reduce the cost of emulsion paint, but also play a role in the skeleton, increase the thickness of the coating film, improve mechanical strength, abrasion resistance and so on. Therefore, it is the most OCP body pigment in latex paint. Heavy calcium carbonate is used in large quantities in primer and putty, and it is a very good jointing material.

The calcium carbonate mill produced by OCP Mining Machinery Co., Ltd. can process the fineness of 200-1500 mesh, which belongs to the high fineness of heavy calcium powder, which has a wide range of uses, and welcome to visit our factory!
