Why we use continuous coating machine to do powder modification?
After the mineral powder is modified by continuous coating machine
, it can not only greatly improve the compatibility of inorganic
mineral fillers and organic macromolecule polymers, increase the
interface bonding force, enhance the mechanical strength and
comprehensive performance of the material, but also greatly improve
the powder filling quantity, reduce the production cost, and at the
same time can give the product some special physical and chemical
properties with the help of continuous coating machine.
The continuous powder surface modification process refers to the
process of continuous feeding and continuous addition of surface
modifiers in the continuous coating machine. Therefore, in the
continuous powder surface modification process, in addition to the
modification host equipment, there are also continuous feeding
devices and additive feeding devices (adding surface modifiers).
Since the production equipment used in the continuous modification
process is different from the intermittent modification equipment,
the modification production can be carried out continuously in
large quantities.
Advantages of continuous coating machine
1. The modifier adopts measures such as dilution, emulsification,
spray addition, etc. to improve the dispersion, continuous spraying
or dripping in conjunction with continuous powder feeding;
2. Precise metering and uniform addition and feeding of modifiers
and materials to ensure the instantaneous accuracy of the ratio of
the two to achieve uniform and firm coating of modifiers on the
powder surface, with good controllability of process parameters and
stable product quality ；
3. The control of system temperature and time should meet the
modification mechanism or the requirements of the modifier on the
process conditions to ensure the adequacy of the modification
reaction or package;
4. Higher powder coating rate and activated rate
5. No leakage of dust; auto control of material feeding by PLC
system; easy operation
6. Continuous production, higher productivity; Running smoothly;
less power consumption
