SLG continuous powder surface modification machine

In the booming wave of modern high technology and new materials, surface modification of mineral powders has become an indispensable key link. It is widely used in many industries such as modern polymer materials including plastics, rubber, adhesives, as well as polymer-based composite materials, functional materials and coatings.

Surface Modification Technology for Mineral Powders

Modification Benefits

Through surface modification, mineral powders can significantly improve compatibility between inorganic mineral fillers and organic polymers, enhance interfacial bonding strength, increase mechanical properties and overall material performance. Furthermore, it enables higher filler loading capacity, reduces production costs, and imparts specialized physicochemical characteristics to end products.

Technical Challenges

However, most conventional non-metallic minerals exhibit poor compatibility with organic polymer matrices due to mismatched interfacial properties. Direct incorporation or high-volume filling often leads to degradation of certain mechanical properties. Therefore, surface modification of inorganic mineral fillers becomes critically important.

Why do we need to modify the surface of mineral powders?

Because most common non-metallic mineral materials have different interface properties and poor compatibility with organic polymer matrices, direct or large-scale filling will lead to a decrease in the mechanical properties of the materials. After modification, the compatibility can be improved, the interface bonding force can be improved, the mechanical strength and comprehensive performance can be enhanced, the filling volume can be increased, the cost can be reduced, and special properties can be given.

Does the SLG type modifier have any requirements for the moisture content of the material when processing the material?

There are requirements. The moisture content of the material should be less than 0.5% to ensure the normal operation and modification effect of the equipment.

What are the advantages of the dust removal system of this equipment?

The dust removal system includes a diffusion cyclone dust collector and a pulse bag dust collector. The pulse bag dust collector uses a new generation of pleated filter cartridges, which have the advantages of small footprint, large filtration area, high dust removal efficiency, and easy cleaning. It can effectively reduce dust pollution and create a good operating environment.

What are the characteristics of the dosing system of the SLG type modifier?

The dosing system is an independent fluid and non-fluid dosing system, which can achieve continuous, stable and uniform dosing, and the temperature control dosing system can arbitrarily set the melting temperature of the agent, which is suitable for various forms of modified agents, ensuring the rational use of the agent and the modification effect.

How to ensure that the original particle shape of the powder is not destroyed during the operation of the equipment?

The powder and the agent are mixed and operated in a high-speed gas-solid vortex in the equipment. This operation mode basically does not destroy the original particle shape of the powder while ensuring the modification efficiency
