The working principle of calcium carbonate coating machine

 

 

 

 

 

 

There is a combination of shear, collision, air vortex and friction in the calcium carbonate coating machine chamber, which can disperse the calcium carbonate powder and increase collision between calcium carbonate powder and modifier. The mixing time of calcium carbonate powder and modifier can be increased by the air vortex. And the temperature can be kept at a suitable degree with the help of collision between calcium carbonate powder and modifier.

Advanced artificial intelligence technology is used to adjust all process parameters and modifier&powder feeding-rate. This can help to achieve the absorption of modifier to calcium carbonate powder surface and stabilize the modified powder quality.

 

 

 

 

 

 

Coated calcium carbonate powder plays a very important role in composite materials production.

 

 

 

 

 

1) Improve the rigidity of composite materials by coated calcium carbonate powder

Coated calcium carbonate powder can improve the flexural strength, flexural modulus, hardness, wear resistance and other properties of the composite material. For plastic films, the improvement of the rigidity of the composite material can significantly increase the stiffness of the film, which is conducive to the smooth curling of the film.

(2) Improve the dimensional stability of composite materials by coated calcium carbonate powder

The improvement of dimensional stability is reflected in reducing shrinkage, reducing warpage, reducing coefficient of linear expansion, reducing creep, and favoring isotropy, etc. Coated calcium carbonate powder filling can significantly improve dimensional stability.

(3) Improve the heat resistance of composite materials by coated calcium carbonate powder

Coated calcium carbonate powder can improve the thermal stability of composites because coated calcium carbonate can absorb substances that promote decomposition. For example, the thermal stability of PBAT/calcium carbonate composite is significantly higher than that of pure PBAT. Another example, especially adding light calcium carbonate to PVC products, can absorb the hydrogen chloride generated by decomposition and greatly improve the thermal stability of PVC processing.

(4) Improve the tear resistance of the film by coated calcium carbonate powder

General plastic films have the shortcomings of high longitudinal strength and low transverse strength, especially PBS, PLA, PHA aliphatic polyester films are more obvious. After adding calcium carbonate, the degree of isotropy of the composite material can be improved, and the tear resistance performance can be obviously improved.

 

 

 

 

 

 

How to achieve satisfactory modification effect by calcium carbonate coating machine?

 

 

 

 

 

 

In the modification process of calcium carbonate powder, in fact, three aspects of fusion and transformation must be realized:

CaCo3 Calcium Powder + Stearic Acid + Energy

At the same time, it is necessary to realize precise feedback control in the process, such as precise weighing method and process constant temperature method, so as to realize the accurate ratio of materials and modifiers. Taking into account the screening and depolymerization of large particle agglomeration, with a very low proportion of stearic acid dosage (0.4%-0.8%), the calcium carbonate powder is perfectly coated.
