Calcium Carbonate Coating Machine with Higher Coated Rate and Temperature Control Device
According to the mechanism and process of surface modification of calcium carbonate powder, the following requirements should be considered when selecting calcium carbonate coating machine:
(1) The calcium carbonate coating machine can heat the calcium carbonate powder to 120℃, and can keep the temperature between 90-120℃, and the heating and mixing time can be controlled automatically.
(2) There is an exhaust device, which can discharge the water that needs to be removed during surface modification in the calcium carbonate coating machine.
(3) Calcium carbonate powder should be in a high-speed dynamic state during surface modification.
(4) The surface modification equipment(calcium carbonate coating machine) should meet the requirements for the addition of surface modifiers.
(5) In order to solve the false agglomerates and hard agglomerates generated in the surface modification by calcium carbonate coating machine, effective classifying must be carried out, and special classifying equipment should be used.
Therefore, when we choose calcium carbonate powder coating machine, we must seriously consider the powder surface modification mechanism and process, and based on this, we can reasonably select and support surface modification production lines.
The working principle of calcium carbonate coating machine:
There are 3 mixing and scattering device in the coating machine. When the machine works, the 3 devices rotate in a high speed to mix powder and modifier and then scatter the powder. The 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 modifier. In the coating machine chamber, the powder and modifier are further contacted and mixed by impacting, sheering and colliding between powder in the high speed mixing chamber. The coating machine always stays within a stable working temperature range to avoid change and invalidity of modifier.
How to improve surface modification effect by calcium carbonate coating machine?
Improving the effect of surface modification mainly starts from three aspects: surface modification method, modification equipment(coating machine) and modifier formula:
According to the preparation process of the calcium carbonate powder surface modification and the surface modifier, we should select the surface modifier that can improve the dispersibility of the calcium carbonate powder and and the techniques that can improve the equality of mutual contact or interaction opportunities between calcium carbonate powder and surface modifier.
We should select coating machine that can make powder and surface modifier well dispersed and have equal opportunities for mutual contact or interaction during the modification process;
We should select surface modifiers and modifiers according to the type of resin binder and application requirements.
