Production line for producing powder coatingsThe manufacturer tells you that powder coating is a new type of solvent-free 100% solid powder coating. It has two categories: thermoplastic powder coating and thermosetting powder coating. Coatings are prepared by mixing special resins, pigments and fillers, curing agents and other additives in a certain proportion, and then through hot extrusion, crushing and sieving. They are stable in storage at room temperature. After electrostatic spraying or fluidized bed dipping, they are heated and baked to melt and solidify to form a smooth and bright coating film to achieve the purpose of decoration and anti-corrosion.

characteristic:
1. The manufacturer of Production line for producing powder coatings tells you that the product does not contain toxicity, solvents and volatile toxic substances, so there is no poisoning, no fire, no "three wastes" discharge and other public hazards, and it fully complies with the national requirements of environmental law.
2. The utilization rate of raw materials is high, and the oversprayed powder can be recycled, with a utilization rate of more than 99%.
3. After the pre-treatment of the object to be coated, it can be applied at one time without primer, and a coating film of sufficient thickness can be obtained. It is easy to realize automatic operation, high production efficiency, and can reduce costs.
4. Production line for producing powder coatings The manufacturer tells you that the coating is dense, with good adhesion, impact strength and toughness, high corner coverage, excellent chemical corrosion resistance and electrical insulation performance.
5. The storage and transportation of powder coatings are safe and convenient.
Powder spraying construction process and requirements: The so-called powder electrostatic spraying is the principle of using high-voltage electrostatic corona electric field. Connect the high-voltage negative pole to the metal diversion mark on the head of the spray gun, and connect the sprayed workpiece to the ground to form a positive pole, so that a strong electrostatic electric field is formed between the spray gun and the workpiece. Production line for producing powder coatings The manufacturer tells you that when the compressed air used as the carrier gas sends the powder coating from the powder supply barrel to the guide rod of the spray gun through the powder pipe, the corona discharge generated by the connection of the guide rod to the high-voltage negative electrode, A dense negative charge is generated near it, which makes the powder negatively charged and enters the electrostatic field with high electric field strength. Under the dual action of electrostatic force and carrier gas, the powder evenly flies to the surface of the grounded workpiece to form a uniform thickness. The powder layer is then heated and cured into a durable coating film.
