High Surface Modification Rate Coating Machine With Higher Output

High Surface Modification Rate Coating Machine with Higher Output

Coating Machine Functions:

    The coating machine can achieve high coating rate with minimal cost. To use coating machine to do surface modification has important practical significance for improving powder performance, improving its practical value and opening up application fields. In polymer materials, plastics, rubber, adhesives and other composite materials, non-metallic powders must be modified into fillers, such as calcium carbonate, kaolin, talc, quartz, asbestos, magnesium hydroxide, hydrogen Alumina, etc., enhance the compatibility with the matrix, dispersibility, mechanical strength and overall performance.

    To use coating machine to do powder surface modification is one of the necessary processing methods for fillers to change from general incremental fillers to functional fillers. This is also the main purpose of surface modification for mineral fillers. The main functions of coating machine include dispersion, viscosity reduction, filling, and interface mechanics. The most commonly used powder modification methods are surface chemical modification methods, coating modification methods, and mechanochemical modification methods. According to the characteristics of modified materials, continuous production process or batch production process can be selected.

      The modifier can be selected from stearic acid or coupling agents (titanate coupling agent, aluminate coupling agent, phosphate coupling agent, etc.). It can achieve ideal activation effect on various inorganic mineral powders. Through dilution, emulsification and spraying, the dispersibility of the modifier is increased.

     The material to be modified is conveyed to the coating machine, where the materials are mixed, dispersed, and then sprayed by the atomized modifier sprayed by a metering pump, and then the powder is uniformly and completely coated. The temperature and time control of the coating machine must not only meet the requirements of the coating mechanism or modifier under technical conditions, but also ensure the adequacy of the coating.

     By uniformly feeding and quantitative feeding of modifier, the adequacy of material coating is ensured. After modification, the powder has multiple functions, such as dispersion, viscosity reduction, filling, and interface mechanics. Personalized solutions for powder surface modification based on material properties and product usage.

Working Principle of High Surface Modification Rate Coating Machine with Higher Output:

    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.
