PPGI steel coil specification
Ppgi is the abbreviation of pre painted galvanized steel coil
It usually refers to steel products such as ppgi coil and ppgi sheet
It is based on the galvanized coil, with certain technology, and then covered with color paint to give the product more colors. The colorful and beautiful surface makes it more widely used.
PPGI coil sizes
Common ppgi widths are as follows
How do ppgi manufacturers produce ppgi
The production process of ppgi is that galvanized steel strip (electro galvanized and hot-dip galvanized) is used as the substrate, after surface pretreatment (degreasing and chemical treatment), one or more layers of liquid paint are coated by roller coating, and the plate obtained by baking and cooling is the coated steel plate. At present, there are back (bottom) paint and surface (front) paint coatings in China. Generally, there is one layer of back paint and two layers of finish paint in China. The finish paint of our factory can be three layers as shown in the figure. The top coat and back coat of foreign business are two layers. Because the coating can have various colors, it is customary to call the coated steel plate ppgi.
Ppgi process flow:
The main production processes of the common two coating and two drying continuous color coating unit are as follows: uncoiler ----- sewing machine ----- pressure roller ----- tension machine ----- uncoiling looper ----- alkali washing and degreasing ----- cleaning ----- drying ----- passivation ----- drying ----- initial coating ----- initial coating drying ----- finish coating fine coating ----- finish coating drying ----- air cooling and cooling ----- winding looper ----- winder ------ lower volume packaging and warehousing.
Ppgi is a color coated steel strip with hot-dip galvanized steel strip as the base material. In addition to the zinc layer protection, the organic coating on the zinc layer plays a role in covering and protecting the steel strip from rust. The service life is about 1.5 times longer than that of the galvanized strip.
Ppgi has light weight, beautiful appearance and good anti-corrosion performance, and can be processed directly. It is mainly used in construction industry, household appliance industry, electrical appliance industry, furniture industry and transportation industry.
The coatings used in ppgi shall be selected with appropriate resins according to different environments, such as polyester silicon modified polyester, polyvinyl chloride plastic sol, polyvinylidene chloride, etc. If you want to purchase ppgi, you can choose according to the purpose.
