Advantages of roll-coated aluminum veneers and sprayed aluminum veneers
Color difference and cost:
A: The roller coating plate is painted flat on the aluminum plate. The height of the oven is 30 cm. The parallel baking surface is always at the temperature curve. The whole process is automated, so there is no temperature difference and no color difference. The roll coating does not have a flow mark due to the single paint coating being too thick. Therefore, the roller can be coated with 2 coats and 2 to meet the 20-year quality guarantee. The quality of the coating completely meets the level of imported aluminum veneer, and the paint utilization rate is over 99%. It belongs to high-efficiency, energy-saving and environmentally-friendly production, and has low cost. It is the development trend of high-grade aluminum veneers and is the trend of aluminum veneer to internationalization.
B: The height of the spraying oven is about 2 meters, and the temperature difference between the upper and lower sides is large. The aluminum plate is placed vertically in the temperature curve. The polyhedral plate formed after forming, the side must be manually refilled, and the one-time spray is too thick and the paint flows downward to easily generate flow marks. Color difference. The paint waste is very large (and ultimately paid by the customer) and the pollution is serious. In order to save costs, the so-called "three-coating and three-baked" of the spraying manufacturer is actually only "two coatings and one roasting". The metal paint of individual spraying manufacturers is "three coatings and one roasting".
Flatness:
A: The roller coated plate adopts 3003H24 series advanced aluminum veneer, and the flat plate is baked at a high temperature, and the internal stress of the plate is fully released. In order to avoid deformation of high-temperature welding, the surface of the roll-coated sheet metal is formed without a welding process, so the aluminum-coated veneer has the characteristics of ultra-flatness.
B: After the forming of the spraying plate is baked at a high temperature, after the stress in the plate is released, the plate is deformed and cannot be flattened. Due to the high temperature of aluminum plate welding, the welding production process is also one of the main reasons for the deformation of the sprayed aluminum veneer.
Surface smoothness and pollution:
A: Roll coating is a pressure-printed coating. The entire coating film layer and surface are non-granular, no micropores, smoother surface and no pollution. Surface dust and other pollutants can be washed away by rain.
B: Spraying is an electrostatic floating coating. The entire coating film layer and surface are composed of particles and micropores. The surface is not smooth and the contaminants are easily penetrated into the surface.
Adhesion and wear resistance:
A: The roller coating is applied by pressure printing, and the adhesion and wear resistance are stronger.
B: The spray coating is a particle stack, and the adhesion and wear resistance are worse than the roll coating.
Film thickness:
A: The roller coating is applied by the flat plate, and the surface of the plate is evenly applied, and the film thickness error is less than 0.5 μm. It is the world's most advanced automated zero-color production process.
B: Spraying due to electrostatic suction coating, the thickness of the surrounding and intermediate coating film is uneven, and the multi-panel must be manually sprayed, and the film thickness error is about 7 microns (one of the chromatic aberration factors).
In summary, the entire process of roll coating production equipment is automated, and the coating quality is fully up to the level of imported aluminum veneers. With zero chromatic aberration, super smooth surface, ultra-flatness, super weather resistance, ultra-low loss, fast delivery cycle, etc., it reflects the development direction of advanced aluminum veneers.
These raw materials are for pharma, mainly for human pharma, such as melbine (DMBG)
It is basic material for many fields, such as pharma, chemical, dying, washing industry, and manufacture industry. Some are powder, some granule, some flake, some crystalline. As below pictures:
It is identified by purity and granule/block size, purity is the main identified method. It is used in different products as per its size.
