Four main functions of galvanized coil surface finishing
1, improve the surface flatness of galvanized sheet. After polishing, the flatness of galvanized sheet is improved to a certain extent, and the wave shape of galvanized sheet is partially eliminated. At the same time, it can also press the slag particles or other uneven points on the surface, so that the surface becomes smooth and smooth.
2, adjust the surface roughness of galvanized sheet. By controlling the surface roughness of the work roll of the polishing machine, the original uneven surface roughness of galvanized sheet can be unified to a certain range. This can improve the coating and processing lubricity of the product.
3, improve the surface color of galvanized sheet. For zinc flower, no zinc flower products, through the finishing can make galvanized plate to obtain a more uniform surface gloss. For some private enterprises to use large zinc flower products as color coating board, can make large zinc flower due to the formation of zinc flower convex point and different gloss get smooth and unified, so that the zinc flower becomes unclear, is conducive to cover off the zinc flower in the painting.
4. Improve the processing performance of galvanized sheet. By polishing, the yield platform of galvanized sheet can be eliminated or not obvious, and metal slip lines can be prevented in future processing.
The corrosion resistance of hot galvanized sheet comes from the
standard electric stage of zinc and the standard electrode
potential of iron. Therefore, the cathodic protection of zinc layer
and maintenance of steel base in water or wet and cold gas greatly
improves the service life of steel crafts. Hot dip galvanized,
phosphating treatment, hot spraying hot dip galvanized, mechanical
equipment hot dip galvanized is the common type of
industrialization, and hot dip galvanized about eighty percent of
all.
The main use of galvanized sheet: cold rolled steel plate into the
melted zinc tank, its surface adhesion of a layer of zinc cold
rolled steel plate. This type of thick steel plate has both
anti-rust treatment function and spraying function. In the electric
welding welding, spraying, rust prevention, etc., with stronger
adaptability. Galvanized sheet according to the main use and can be
divided into general use, house use, engineering building on both
sides of the board, structure, corrugated board with, with and low
alloy plate galvanized sheet.
