How to improve the leveling of powder coatings?

How to improve the leveling of powder coatings? Powder coating is a new type of solvent-free 100% solid powder coating. It has two major categories: thermoplastic powder coatings and thermosetting powder coatings. The coatings are made of resin, color filler, curing agent and other additives, mixed in a certain ratio, and then prepared by the process of hot extrusion and crushing through the sieve. They are at room temperature, storage stability, by electrostatic spraying or fluidized be

How to save the leftover thermosetting powder coating when spraying

How to save the leftover thermosetting powder coating when spraying The powder produced by powder paint is prepared by special resin, color filler, curing agent and other additives, mixed in a certain ratio, and then prepared by the process of hot extrusion and crushing through sieve. They are at room temperature, storage stability, by electrostatic spraying, friction spraying (thermosetting method) or fluidized bed dip coating (thermoplastic method), and then heated and baked melt curin

The difference between thermosetting and thermoplastic powder coatings

The difference between thermosetting and thermoplastic powder coatings Thermosetting refers to the heating can be cured cross-linked, cross-linked coating does not melt or dissolve, there is a chemical reaction during the heating process. Thermoplastic refers to the heating of the powder can soften, but will not cross-link, the heating process only physical changes without chemical reactions. Specific performance differences are as follows. Thermoplastic

The function of the surface adjustment process and its control points

The function of the surface adjustment process and its control points After degreasing phosphating before the surface adjustment is an important process to generate phosphate film crystallization. It changes the microscopic state of the metal surface, prompting the phosphating process to form crystalline fine, uniform, dense phosphate film. In particular, the metal surface cleaned by pickling or high-temperature strong alkali and dipping low-temperature low zinc film

Degreasing and phosphating in surface pretreatment

Degreasing and phosphating in surface pretreatment Degreasing. Phosphating solution excellent phosphate film as long as the oil is removed completely on the exterior of the workpiece to constitute, cleaning agents due to oil residue on the exterior of the workpiece will not only severely prevent the growth of phosphate film, and will also affect the adhesion of the coating film, drying function, decoration function and corrosion resistance.

Reasons for bad curing of powder coating film

Reasons for bad curing of powder coating film Abstract: Unlike the liquid coating liquid volatile norm, powder coating coating dust spillage is its norm, good imported equipment is expensive, reasonable design, large safety margin, dust is not too serious; cheap equipment in the design is almost no margin, coupled with maintenance can not keep up, spare parts scrap replacement is not timely, the use of powder particle size and material bad, to catch up with the production schedule, and t

Commonly used metal surface treatment methods and their characteristics

Commonly used metal surface treatment methods and their characteristics In the process of heat treatment, machining, transportation and storage, the metal surface will inevitably be oxidized, resulting in a layer of uneven thickness of oxidation. Let's summarize what are the common methods of metal surface treatment? Mechanical treatment method: mainly including shot blasting method and shot blasting method. Shot blasting method is a method of cleaning using c

Technical requirements of powder coating for electrostatic spraying process

Technical requirements of powder coating for electrostatic spraying process The significant difference between powder coatings and solvent-based coatings is the different dispersion media. In solvent-based coatings, organic solvents are used as the dispersion medium; in powder coatings, purified compressed air is used as the dispersion medium. Powder coatings are dispersed when sprayed, and the granularity of the coating cannot be adjusted. Therefore, the fineness of the powd
