Surface modification (activation) has important practical significance to improve the performance of powder, improve its practical value and open up the development of application fields. In plastics, rubber, adhesives and other polymer materials and composite materials, non-metallic powder fillers, such as calcium carbonate, kaolin, talc, quartz, wollastonite, asbestos, magnesium hydroxide, aluminum hydroxide, etc., must be on the filler surface modification, enhance its compatibility with the matrix, dispersion and mechanical strength and comprehensive performance.

Surface modification (activation) is one of the necessary processing means for fillers to change from general extender fillers to functional fillers, and it is also the main purpose of surface modification of mineral fillers. The main effects of surface modification of mineral fillers include dispersion, viscosity reduction, filling and interface mechanics.

The most commonly used modification methods are mainly surface chemical modification, coating modification and mechanical force chemical modification. There are many types of surface modification equipment, specially designed, but also from the chemical, plastics, crushing and other industries to use. Some devices can be used not only for surface modification or coating, but also for encapsulation and spheronization.

continuous surface modificationCladdingMachine“Honeycomb mill"-It is mainly suitable for coating modification of various mineral fillers, such as calcium carbonate coated with stearic acid, such as large treatment capacity, high coating rate, small additive addition, automatic control, continuous production, stable product quality, negative pressure transportation without dust pollution.

Operating conditions include rotational speed, throughput, solid-gas ratio concentration, etc.MainThe use of forced eddy current to the material and modifier dispersion, mixing and mechanical force chemical action to achieve modification.,According to the characteristics of the material, different materials can be used inside the equipment, which has the advantages of retaining the color and purity of the material, and the coating rate can reach99.2%, the activation rate was 99.8%.

Choose the correct modification process and equipment according to the surface modification method and the type of modifier and the use requirements. The surface modification process should meet the application requirements or application conditions of the modifier, the modifier dispersion is good, the modifier can be uniformly and firmly coated on the surface of the powder, the process parameters are controllable, and the product quality is stable.
