Powder coating and traditional coating sitesting big PK

outlinethes the advantages of powder coatings: solvent-free, volatile organic compounds are zero due to pinhole problems, it is difficult to obtain ultra-thin coatingsgenerally speaking of the advantages of powder coatings: no solvent, volatile organic compounds zero due to pinhole problems, it is difficult to obtain ultra-thin coating (thickness less than 1.0 mils)the exhaust gas discharged from the coating chamber can be returned to the coating chamber, can reduce the domestic and foreign from the oven Frequent color changes in the platoon will increase the downtime of the overspray powder can be recycled and reused for storage and treatment of powder, requiring special climate control without drying or flashtime, and the to-coat parts can be arranged in tighter color matches and slightly difficult liquidscoatingsuitable for continuous, automatic process coating thickness of the homogeneity is sometimes difficult to maintain
coating does not flow, does not drop, can reduce the scrap rate of temperature-sensitive parts, some powder curing temperature is too high
the least number of construction personnel training and supervision of sharp corner parts difficult to powder coating
easy to obtain a thicker coating from the liquid coating process powder to coating process conversion expensiveproduction capacity Due to the Faraday cage effect, the inner angle coating thickness is thin
cleaning and maintenance simple

1Reduce environmental pollution
reducing environmental pollution
with the environmental protection decree on the atmosphere organic volatiles (VOC) content more and more stringent provisions, coating industry to seek various ways to improve coating technology to reduce environmental pollutionAfter a long period of experiments and tests, it is finally found that "powder coating" is the most ideal coating technology can be achievedpowder coatingdoes do not use organic solvents, water and other volatile solvents, so powder coatings for inorganic solvent-based coatings, greatly reducing the safety hazards caused by solvents, such as the operator organic solvent poisoning incident caused by organic solvents, or because of organic solvents caused by fireSince the introduction of powder coatings in the 1950s and 1960s, there have been no major safety accidents caused by powder coatingspowder coating is 100 percent solid powder-like coating, fully fully automatic sprayExcessive or overspray powder coatings can be recycled through the recycling system device, so powder coatings can be used by almost 100 percent, so the coating industry to reduce waste treatment, while reducing the degree of environmental pollution to a minimum2Energy conservation
the energy costs of powder coatings and liquid coatingsLiquid coatings, which contain organic volatiles, cause volatiles to evaporate into the atmosphere, while powder coatings do not waste this kind of waste, greatly reducing energy useelectrostatic coating machine spit out a large amount and a spray can be thick film, do not have to repeat spraying, do not have to paint, in the same film thickness, the use of powder coating coating work is relatively rapid, can save time and costdo not require a stationary time (SettingTime) in a coating device, saving space In addition, the baking time of powder coating is less than liquid coating, so that the fuel energy can be greatly reduced, shorten the coating line, improve production capacity, promote the efficiency of overall production 3 Excellent coating performance
as long as the powder coating is directly applied to iron or aluminum after proper pre-treatment, etc , after baking can get excellent performance of the coating surface, such as coating film persistence, including: wear-resistant rub, impact, tightness, toughness, corrosion resistance and chemical resistance performance And outdoor powder coatings, in addition to the above advantages, but also include high weather resistance and pollution resistance Especially thick coating film, powder coating can reach 50-300 m at a time, and the leveling is good, will not be like solvent coating thick coating will have drip or build-up and other phenomena to enhance the versatility of powder coatings, the color, gloss and surface flatness can be adjusted according to customer preferences, even special metal powder coatings and some special wrinkle powder coatings 4 Considerable economic benefits
because of the powder coating using electrostatic principle coating, coating equipment can achieve full automation, without wasting human resources Even if human assistance is required, the coating personnel do not have to undergo long-term training to spray a good coating film Powder coatings are 100% solid and do not require any solvents, saving packaging and reducing storage space During the spraying process, if there is a poor spray, you can use an air spray gun to blow it off before baking, and then spray it As a result, surface fluids and drops are unlikely to occur, reducing the probability of repainting In the composition of coating, solvent-based coatings are about 60 to 65%, while powder coatings can reach almost 100%, and powders that are not attached to the sprayed objects can be recycled In general, powder coating technology can improve productivity and economic efficiency
