What is Powder coating and surface modification production line

The powder coating and surface modification production line is also named as powder modification machine,powder surface modifying machine / equipment,mineral powder Coating machine / equipment, which is mainly responsible for three purposes, the first is mixture, the second is dispersion and third is surface modification to the powder via a specified melting modifier, resulting in a good combination. It can be divided into continuous modified production technology and batch ones, also there are two combinations of processes.

Industrial basic technical requirements:
  • Dispersity of modifier is increased by means of dilution, emulsification and spray.
  • The material to be modified is fed into the coating machine, where the material will be mixed, dispersed and then coated by atomizing modifier sprayed by dosing pump and the the powder will be coated evenly and completely.
  • Control of system temperature and time is so regulated not only to meet the requirement for coating mechanism or modifier on technical conditions, but also to guarantee coating reaction or coating sufficiency.
  • The coordination of feeding material and modifier ensure the complete coating.
  • In conjunction of accessories ( depolymerizing machine or classifier), the product quality will be improved largely.
  • We achieve the highest coverage or modification with minimal coating material or cost
  • Surface modification has important practical significance for improving the performance of powder, improving its practical value and developing the application field.
  • In polymer materials, composite materials such as plastics, rubber, adhesives, etc., non-metallic powders must be modifieds a filler ，Such as calcium carbonate, kaolin, talc, quartz, wollastonite, asbestos, magnesium hydroxide, aluminum hydroxide, etc，to enhance their compatibility with the matrix, dispersion, mechanical strength and overall performance.
  • Surface modification is one of the necessary processing means for the filler to change from general incremental filler to functional filler. It is also the main purpose of surface modification of mineral filler.
  • The main effects of surface modification of mineral powder fillers include dispersion, viscosity reduction, filling, interface mechanics.
  • The most commonly used powder modification methods are surface chemical modification method, coating modification method, mechanical force chemical modification method.
  • According to the characteristics of the modified materials, continuous production process or batch production process can be selected.
  • There are many options for modifying equipment
  • The modifier can be selected from stearic acid or a coupling agent (titanate coupling agent, aluminate coupling agent, phosphate coupling agent, etc.)
  • Wide application, can achieve the desired activation effect on various inorganic mineral powders.
  • Dispersity of modifier is increased by means of dilution, emulsification and spray.
  • The material to be modified is fed into the coating machine, where the material will be mixed, dispersed and then coated by atomizing modifier sprayed by dosing pump and the the powder will be coated evenly and completely.
  • Control of system temperature and time is so regulated not only to meet the requirement for coating mechanism or modifier on technical conditions, but also to guarantee coating sufficiency.
  • Ensure the adequacy of material coating by uniform feeding and coordination with the quantitative feeding of modifiers
  • In conjunction of accessories ( depolymerizing machine or classifier), the product quality will be improved largely.
  • After modification, the powder has various functions such as dispersion, viscosity reduction, filling, interface mechanics.
  • Personalized solution for powder surface modification based on material properties and product use
