Magnesium silicate is the chemical name of talc powder. Talc mines are very rich in reserves around the world, usually a mixture of various crystal forms. Generally, the deep processing of talc ore powder must be ultrafine milled, which is ground into fine powders of various sizes, and then applied to various fields.
The influence of industrially produced talc powder on the performance of the coating is controlled by its structure type, powder fineness and particle size distribution. Therefore, we will classify the talc powder products: fibrous talc powder, flake talc powder, granular talc powder.
Merchants process talc powder through ultrafine grinding mill, and the particle size ranges from coarse, medium and fine. There are varieties on the market that have undergone surface treatment and have low oil absorption, which is suitable for photomagnetic poles. Talc is easy to wet and disperse in all liquid coatings, such as organic solvents, varnishes, alkyds and water-based systems. Talc powder has excellent suspendability in coatings, and can also help other pigments in the system to remain suspended.
Talc powder with coarser particle size is suitable for some coatings that require rough coating or "toothed", such as interior wall paint, primer and crepe paint. Varieties of medium particle size are suitable for house paints and can also be used as general fillers. Superfine talc powder is suitable for controlling the gloss, consistency and sagging properties of semi-gloss coatings. The amount of talc is large in cement, crack filler and putty. Special products decide to choose coarse or fine talc powder according to different requirements.
It can be seen from the application of talc powder that both coarse and fine powders are widely used. SBM Raymond ultrafine mill can process coarser talc powder, fine powder ultrafine mill can process finer powder, ultrafine mill can process talc ore to more than 1500 mesh powder, SBM ultrafine mill series products It is getting more and more applications in the field of talc processing.
