A. Color coating knowledge
The types of color-coated substrates include cold-rolled substrates. Hot-dip galvanized substrates, and galvanized substrates.
According to the requirements of users, the color of the color-coated board is orange, milky yellow, etc..
Dark sky blue, stone blue,dark red, ivory white, porcelain blue, etc.
Color-coated boards, embossed boards, and printed boards classify according to the surface state of the color-coated boards.
Color coated boards have certain uses in the three parts of construction, household appliances and transportation.
This is another classification based on market uses.
The construction sector accounts for the largest proportion.Followed by home appliances,
and the transportation industry only accounts for a small number of sectors.
Color-coated panels for construction generally use hot-dip galvanized steel sheet and hot-dip aluminum-zinc steel sheet as substrates.
Which mainly processe into corrugated sheets or composite sandwich panels with polyurethane.
Which used to build steel structure workshops, airports, warehouses, and freezer.
Roofs, walls, doors for industrial and commercial buildings.
Because the zinc layer of the galvanized steel sheet is very thin. It is not suitable for use in roofs, exterior walls and other applications.
However, because of its beautiful appearance and superior processability.
Interior decoration and other materials.
Color plates for home appliances are generally based on electrogalvanized and cold plates for the production of refrigerators and large
air-conditioning systems, freezers, bread makers, furniture, etc.
In the transportation industry, electroplated zinc and cold plates are generally used as substrates,
which are mainly used in oil pans and automotive interior parts.
B. Embossed steel sheet and skinned steel sheet
①Skin-coated steel plate: Apply a layer of adhesive on the substrate first, and then laminate the film of PVC or PVF material. It belongs to
the most advanced color-coated products at present, with beautiful appearance and excellent durability.
②Embossed steel plate: There are two types of coating embossing and metal embossing.
Coating embossing: coated with PVC plastisol on galvanized steel, its coating film thickness can reach 100 ~ 400um, after baking,
The embossing roller resse to form a patterned coating film, which is beautiful and durable, and has good corrosion and processability.
and can usded in buildings, interior decoration, building materials, furniture, etc.
Metal embossing: Coating embossing only the coating emboss and metal embossed metal substrates also emboss with concave and
convex patterns. Because metal deformation is more difficult, the thickness of colored steel produced generally does not exceed 0.60mm.
Due to its excellent three-dimensional feel, it widely used in interior decoration panels and other applications.
