The reason why use calcium carbonate coating machine:
Calcium carbonate is a kind of versatile inorganic filler, because there are many hydroxyl groups on the surface that can easily absorb water and make powder hydrophilic and oleophobic. The interface formed by the matrix is poor in adhesion. In order to make full use of calcium carbonate powder, powder should be made be as small as possible, which has the disadvantages: easy to reunite because of the extra large surface and surface property. After reunion, the powder cannot be used properly. So it is necessary to do calcium carbonate powder surface modification.
Coating machine 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.
Special Features of Calcium Carbonate Coating Machine
1. 100% of the surface of all powder particles can be coated with modifier ( with special spray technology)
2. Higher powder coating rate and activated rate
3. No leakage of dust; auto control of material feeding by PLC system; easy operation
4. Continuous production, higher productivity; Running smoothly; less power consumption
This equipment consists of 1. powder feeding device 2. modifier metering device 3. Spraying device 4. coating chamber 5. pneumatic system 6. pulse-jet collector 7. electric control cabinet
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.
