Does the walling compound "crack upon application" or "shine like a mirror"? The difference lies in this equipment.
Even with the same types of calcium carbonate powder, adhesive powder, and cellulose, why is one walling compound easy to apply, firmly bonded, and does not peel off after drying; while the other is difficult to apply, shrinks and cracks, and loses powder during grinding? You can buy the same raw materials, but if the equipment is not selected correctly, even the best formula is wasted.
The core of walling production lies in the uniformity of mixing and precise measurement. High-quality walling compound requires that all components be fully dispersed at the microscopic level - the distribution of adhesive powder is uneven, and the local bonding strength is insufficient; the distribution of cellulose is uneven, and the water retention effect varies greatly; even the fineness fluctuation of calcium carbonate powder can affect the construction feel. These differences directly depend on the design, rotational speed, residual rate of discharge, and accuracy of the metering system of the mixer.
