Calcium Carbonate Coating Machine with 3 Mixing and Scattering Chamber for Higher Coating Rate
The application of calcium carbonate in polymer-based composites is unevenly dispersed and has low interfacial bonding force, which causes defects between the composite materials interface, resulting in the reduction of tensile strength, impact strength, elongation at break and other mechanical properties of rubber and plastic products, thereby affecting Its application effect, and this defect becomes more obvious with the increase of calcium carbonate filling amount, and even makes the product unusable. In order to enhance the wettability of calcium carbonate in polymers, eliminate high potential energy on the surface, improve its dispersion and hydrophobicity and lipophilicity in composites, improve the processing and mechanical properties of calcium carbonate filled composites, and improve its performance in composites The filling amount of calcium carbonate needs to be modified.
Coating machine is a kind of machine which is used to modify the surface of calcium carbonate power to improve the physical and chemical properties of its surface, and to reinforce compatibility and dispersion with organic polymers or resins, and to improve the mechanical strength and comprehensive performance of materials. 325-6000mesh calcium carbonate powder can be modified, whose size will not become bigger after modification. After the change of calcium carbonate powder physical and chemical properties, it also brings the following advantages: surface composition, structure and functional group, surface energy, surface wettability, and electrical properties. The modified calcium carbonate powder with these features can meet the need of development in the new material and new production techniques.

Working Principle of Calcium Carbonate Coating Machine:
Calcium carbonate coating machine includes 3 mixing&scattering chamber, which can rotates in a high speed inside. In this way, modifier and powder can be mixed fully and will not reunite. The calcium carbonate powder and modifier go through the 3 devices one by one. At the same time, the modifier is being sprayed in the spraying room under the control of metering pump, which will be fully mixed with powder. In the coating machine chamber, the powder and modifier can be further contacted and mixed by impacting, sheering and colliding between powder. The coating machine always stays within a stable working temperature range to avoid change and invalidity of modifier.
