Thermoplastic Polyethylene LDPE Powder Coat for Clothes Hanger
Thermoplastic polyethylene LDPE powder coating for metal clothes hangers is a coating material that takes low – density polyethylene (LDPE) as the base material and is applied to the surface of clothes hangers through specific processes. The following is a detailed introduction to it:
Basic Information
- Composition: It is mainly made of high-pressure polyethylene (LDPE) as the base material, and is equipped with a variety of functional additives and color pigments. Functional additives can enhance the performance of the coating, such as improving weather resistance and impact resistance, while color pigments can make the coating present different colors to meet the decorative needs of clothes hangers.
- Coating Properties
- Chemical Resistance: It has excellent acid and alkali resistance and chemical resistance, and can resist the erosion of common chemicals in daily life, so that the clothes hanger is not easy to be corroded and damaged.
- Mechanical Properties: It has excellent flexibility and impact resistance. When the clothes hanger is impacted or bent, the coating is not easy to crack or fall off, which can well protect the substrate of the clothes hanger.
- Low Temperature Resistance: It has good low temperature resistance. It can be placed at -30°C for 400 hours without cracking, and can be used normally even in cold northern environments.
- Insulation Performance: It has good thermal insulation and electrical insulation properties, which can avoid the occurrence of electric corrosion and has certain safety.
- Decorative Performance: The coating surface is smooth and has a moderate gloss, and can be made into different colors, which can improve the appearance quality of the clothes hanger and meet the aesthetic needs of consumers.
- Safety and Environmental Protection: Non-toxic and meets environmental protection requirements, so it will not cause harm to the environment and human health during use.
Process Of Applying polyethylene LDPE Powder on Clothes Hangers
The first step is to send the hanger into the baking tunnel for preheating.
Its function is to heat the hanger to the temperature above the melting point of the thermoplastic polyethylene LDPE powder, so that the powder can be wrapped in the hanger and softened by heat.
The conveyor belt needs to be covered with thermoplastic polyethylene LDPE powder, and the hanger is buried in the powder. Under the action of the blower, the powder slowly rotates, jumps and rolls in full contact with the “hot” hanger. The powder near the hanger will melt and coat the wire hanger.
So the question is, will the blower send the powder particles flying around the sky? Not really.
Flowing dip is compressed air running through the bottom of the line. The whole polyethylene LDPE powder is somewhat similar to the effect of quicksand, flowing inside to completely coat the wire hanger. The clothes hanger is coated with powder, and the excess powder is shaken off by vibration, and then collected on the pole.
The process is not completely finished, and then the clothes hangers adhered with polyethylene LDPE powder must be baked and cured again at high temperature. Its function is to make the outermost surface of the hanger a softened uniform coating.
Finally, manual quality inspection will pick out the defective products with scratch damage, and this part will be baked twice for curing.
Advantages of Application of Polyethylene LDPE Powder on Clothes Hangers
- Extended Service Life: The coating can effectively protect the clothes hanger from corrosion, impact and other damages, reduce the wear and aging speed of the clothes hanger, and prolong the service life of the clothes hanger.
- Improved Aesthetics: The coating has a variety of colors and a smooth surface, which can make the clothes hanger more beautiful and enhance the market competitiveness of the clothes hanger.
- Cost – Effectiveness: The raw material cost of LDPE powder coating is low, and the coating process is relatively simple, which can reduce the production cost of clothes hangers while ensuring the quality.
- Environmental Friendliness: It is non-toxic and meets environmental protection requirements. Unlike some traditional coatings that may contain harmful substances, it will not cause pollution to the environment during production and use.
