Introduction of Organic Coating Packaging Steel Strip
A. PVC plastisol coated packaging steel strip
Polyvinyl chloride plastisol is a dispersion of powdered polyvinyl chloride in a plasticizer. Roll-coated a layer of this plastisol with a thickness of 0.08-0.4mm on the surface of the galvanized steel sheet. After drying, it becomes polyvinyl chloride. Plastic coated steel sheet. This kind of steel plate has good formability and low cost.
B. PVC Organosol Coated Packaging Steel Strip
Polyvinyl chloride organosol is a dispersion of polyvinyl chloride in plasticizer and solvent. Roll coating of about 0.03-0.06mm thick organosol on the steel strip, and dry it to form a polyvinyl chloride organosol coated steel strip. Compared with the plastisol-coated steel strip, this kind of steel plate has defects when it is bent and deformed.
C PVC laminated packaging steel tape
A layer of 0.2-0.3mm thick PVC film is coated on the steel plate to make PVC laminated steel strip. This steel plate can be bent 180%, and the inner radius of curvature can be equal to the thickness of the plate. The speed of roll forming is lower than that of ordinary packaging steel belts, and the pressure of the forming roll is lower. If the pressure is too large, the surface of the section steel will be scratched or imprinted, so lubrication measures should be taken. Single-sided and along-surface PVC laminated packaging steel strips can be made into cold-formed steel products with quite complex cross-sectional shapes.
D acrylic-based coated packaging steel strip
Biene-based paint is a resin prepared by the addition reaction of propylene or methacrylic acid derivatives and other unsaturated monomers (such as styrene). It is a thermosetting coating. The coating film thickness of the packaging steel strip is 0.005-0.025mm, which can withstand roll-type cold bending forming, but the bending radius should not be too small, otherwise the surface will crack.
E painted packaging steel strip
0.3-0.6mm thick cold-rolled steel sheet is treated with hot-dip galvanizing, electro-galvanizing or phosphate, then roll-coated with enamel, and dried to become a painted steel sheet. This kind of packaging steel strip can be processed by cold bending and the forming speed is 30m/min.
