Surface coating mechanism and process requirements

Creating the future of advanced materials with powder technology.

Coating mechanism

  1. The basic principle of coating: obtain the highest coating rate or coating effect with the minimum coating material or cost;
  2. Surface coating of mineral fillers, the main functions include dispersion, viscosity reduction, filling, and interface mechanics;
  3. The most commonly used coating methods are: surface chemical coating method, coated coating method, mechanical force chemical coating method;
  4. The coating methods mainly include: coating mechanism, modifier, coating process and equipment, process control, product testing and evaluation;
  5. If the purpose, method and modifier of the coating are different, the process and equipment are also different.

Basic Process Requirements

  1. The modifier uses dilution, emulsification, spray addition and other measures to improve the dispersion, preferably continuous spray or drip with the continuous feeding of the powder;
  2. Precision metering and uniform feeding of modifier and materials to ensure the instantaneous precision of the ratio of the two, to achieve uniform and firm coating of the modifier on the surface of the powder, good controllability and stable product quality;
  3. The regulation of the temperature and time of the system should meet the requirements of the coating mechanism or the modifier on the process conditions, and ensure the sufficiency of the coating reaction;
  4. the equipment operating conditions are good;
  5. The use of auxiliary equipment (deagglomerator or classifier), environmental factors (temperature, humidity), etc.

Continuous coating process

A.”Double-power Pin disc grinding + deagglomerator machine” continuous coating process

Commonly used classic crafts by european and American well-known mineral companies.
