PPGI Knowledge

1 Overview of PPGI

PPGI is based on hot-dip galvanized sheet, hot-dip galvanized sheet, electro-galvanized sheet, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of agricultural production system coatings are applied on the surface. , and then baked and cured products. It is also named after the PPGI coated with various colors of agricultural production system coatings, referred to as color coated coils.
The PPGI steel strip using hot-dip galvanized steel strip as the base material is protected by the zinc layer, and the agricultural production system coating on the zinc layer plays a covering and protective role to prevent the steel strip from rusting, and its service life is longer than that of the galvanized coil. , about 1.5 times.

2 The properties of PPGI

Substrate mechanical properties (yield strength, tensile strength, elongation)
Coating properties (coating type, coating adhesion, coating weight)
Coating properties (film thickness, T-bend, impact, pencil hardness, chalk resistance, salt spray resistance, durability, etc.)
Surface quality (defects, gloss, color, coating fineness, etc.)
Other properties (form, dimensional accuracy, tolerance, etc.)

3 Application of PPGI

PPGI is light, beautiful and have good anti-corrosion properties, and can be directly processed. The colors are generally divided into gray-white, sea-blue and brick red. They are mainly used in advertising, construction, household appliances, electrical appliances, furniture and transportation Industry.
The paint used in the PPGI coil selects the appropriate resin according to the use environment, such as PE, PVDF, SMP, HDP, etc.
