Powder coating because has the advantages of environmental protection and superior performance in the past few decades in the metal product and heat sensitive material products rapid popularization and application. And fast coil coating due to the requirement of surface coating, coating thickness thin, etc, so the application of powder coating on the coil coating has been limited. But in recent years, along with the people environmental protection consciousness and constantly improve the requirements of environmental protection by the government, to find a way of environmental protection of the coating is imminent.
MEIAO first use of technological innovation, improve the quality of products, and actively committed to environmental protection to popularization and application of powder coatings in coil coating, powder coating for coil coating manufacturing company set, coating equipment and coating technical support and new product development as one of the coil of powder coating, the solution for end users to provide environmentally friendly products.
Powder coatings
To end carboxyl fast curing weather resistance type polyester resin as the main body, cooperate with fast curing curing agent, after reasonable formula design, preparation equipment preparation in a specific powder. Powder product has the characteristics of particle size small, scattered not reunion, spraying coating achieve 28—38 microns, surface flow leveling effect is good, can achieve 5 to 20 years of fixed number of year of the outdoor weather resistance, and according to customer requirements can be achieved from the clean, anti—bacterial, anti—corrosion coating surface such as a specific function, excellent comprehensive performance. Product specific gravity 1.1—1.5 g/m³, in 32 microns of film thickness can be achieved 18 to 26 m²/kg of the spraying area.
MEIAO first use of technological innovation, committed to the popularization and application of thin film type powder coatings, successively in coil, thin coating of powder coating applied to a number of invention patents, the company has independent intellectual property rights.

Coating equipment
Coil coating powder special coating equipment is divided into powder coating and powder melting solidification. Powder coating area is suitable for high—speed spraying application advanced electrostatic spray gun, realizing high speed plate surface spray coating uniformity of powder. Powder melting solidification area using halogen and medium short wave infrared heating components, has quick melting solidification for powder coating, energy conservation and environmental protection technology advantage.
MEIAO were first designed and developed for coil coating powder coating equipment to realize the high—speed coating of 60—100 — m/min, production process and no volatile, no odor, no waste water emissions, to achieve the whole process of coating completely the technical requirements of environmental protection.
MEIAO is first actively committed to environmental protection to popularization and application of powder coatings in coil coating, continuous technological innovation, improve the quality of coating production line, and has applied for a number of coil in the field of powder coating equipment for a patent for invention and utility model patents.
Coating technology
MEIAO have efficient and professional technical team, in the positive development of coil (thin coating type) of powder coating solutions for new technology at the same time, can timely insight into the latest needs of customers, for customers to provide quality technical services. Mai fu coating solution according to customer‘s actual demand, is equipped with a full set of technical documents, operation procedures, testing standard and other standard documents, active communication with the customer training, equipment upgrades, optimization, and powder coating to provide free technical guidance and technical support.
