The thermoplastic powder coating has the characteristics of softening under heat and solidifying into a film after cooling, and is mainly a physical melt plasticizing film forming process. Thermoplastic powder coatings were applied earlier. As early as the mid-1940s, Europe has studied the research and experimental work using thermoplastic powder coatings for more than 30 years.

Thermoplastic powder coatings were applied earlier. As early as the mid-1940s, Europe has studied the research and experimental work using thermoplastic powder coatings for more than 30 years. There are many varieties of thermoplastic powder coatings that can be applied, and are typically polyethylene, polypropylene, polyvinyl chloride, polyamide, thermoplastic polyester, chlorinated polyether, polytetrafluoroethylene, and the like. Thermoplastic powder coatings are suitable for use as anti-corrosion coatings, abrasion resistant coatings, non-toxic coatings and general decorative coatings. The scope of application is mainly in chemical equipment, chemical pipelines, chemical storage tanks, plates, wires, mechanical parts, light industrial appliances and food industry. With the advent of electrostatic spraying and electrostatic fluidized bed methods, the scope of application has been further expanded, and instruments, electronics, machinery, automobiles, construction and other industries have also applied. In recent years, due to the expansion of the market, the improvement of the coating process has been applied to the textile industry. At present, the application of thermoplastic powder coatings in China has a new development, and the amount of use has also increased significantly. The remarkable characteristics of thermoplastic powder coatings are simple processing and preparation, the coating film has excellent chemical properties and good mechanical properties, and some varieties have outstanding wear-resistant lubricity, and the price is generally low. However, such resin powder is difficult to pulverize, the particle size is coarse, the gloss and leveling property of the coating film are poor, the mechanical strength is not ideal, and the adhesion to the metal is poor, and the drum generally needs to be pre-coated with a primer to be used. The comprehensive analysis has the following excellent characteristics. 1. Excellent chemical stability. 2. light in mass 3. Excellent electrical insulation performance 4. Excellent anti-friction, wear resistance, shock absorption, noise reduction performance. The above characteristics of the plastic powder make it widely used in the industry. In order to expand the range of application of thermoplastic powder coatings, the heat resistance, rigidity and decorative properties of the resin are further improved. From the current point of view, in addition to the addition of various auxiliary materials, resin modification methods can also be used to achieve the desired results. Recently, there have been many modified varieties of thermoplastic powder coatings, which have improved the gloss, hardness, adhesion, elasticity and other properties of the coating, and met the requirements of some products. Such as: 1. Rare resin modified polyethylene enhances surface hardness and improves adhesion. 2. Vinyl acetate copolymer modified polyethylene improves coating toughness and surrounding stress cracking. 3. Polypropylene modified polyethylene improves surface strength and improves mechanical strength. 4. Polybutylene modified polyethylene improves mechanical strength and gloss. 5. Cellulose acetate modified polyethylene improves strength and leveling performance. 6. Polycarbonate modified polyethylene improves stress cracking and enhances durability. 7. Epoxy resin modified polyamide improves corrosion resistance and enhances adhesion. Aluminum Spiral High Speed Door
The Spiral door offers high-speed operation for high-traffic situations and rigid aluminum slat construction that eliminates the need for a second security door. Crisp lines give the Spiral door a stylish look that's great for many types of commercial, automotive retail, government, institutional and industrial applications. The Spiral is ideal for automotive dealerships, government, parking and security. Benefits No metal-to-metal contact reduces wear on the door panel and offers fast, quiet operation.
Aluminum spiral High Speed doors are usually used wherever goods traffic occurs and where the doors have to fulfill special requirements. In the food and beverage industry, or Medical industry for example, special climatic conditions have to prevail; short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
