Powder Surface Modification Machine

Powder surface modification machine is the inevitable product of modern high technology and new material development. Recently, it becomes more and more popular. It is widely used in nonmetallic mineral fillers, plastics, rubber and other modern polymer materials, functional materials and coatings industries and other related industries.

Why should the powder be modified? After modification, the powder can not only greatly improve the compatibility between inorganic mineral filler and organic polymer, improve the interface binding force and enhance the mechanical strength and comprehensive properties of the material. Moreover, it can greatly increase the filling amount of powder, reduce the production cost, and endow the product with some special physical and chemical properties.

Therefore, looking for a suitable and high-quality of powder surface coating modification machine is very crucial.

Different types of powder coating machine

About the types of mineral powder coating machine, our Daswell Machinery company provide our clients with different choices, like vortex mill coating mill, three roller coating machine, high-speed mixing coating machine, etc.

The vortex mill coating machine adopts conical rotor and stator, by adjusting the clearance of rotor and stator to control the fineness and output. Its powerful eddy current flow field makes the material instantaneous crushing, so the material stays in the cavity for a short time, without temperature rise. Nowadays, the new type vortex mill coating machine with classifier is the most advanced coating solution for calcium carbonate in China.

Three-roller coating machine can change the action of cyclone vortex through the relative movement of three rotors to realize the coating of powder surface. Because it can achieve self-friction heat generation, it does not need a heating device, which can save your investment cost.

The high-speed mixing coating machine is suitable for the modification of materials with high modification temperature and long reaction time by silane and other additives.

Process requirements of modification

The basic principle of modification is to obtain higher coating rate or modification effect with less coating material or cost. There are many common modification methods, including surface chemical modification, coating modification, mechanochemical modification, etc. The purpose, method and modifier of coating are different, and the modified equipment is also different.

For the basic process requirements of modification, there are the following aspects: The precision measurement and uniform addition and feeding of modifier and material ensure the accuracy of the ratio of the two. And realize the uniform and firm coating of modifier on the surface of the powder, and the product quality is stable; The control of temperature and time of the system should meet the requirements of the process conditions of the modifier to ensure the adequacy of the modification reaction or coating.
