PPGI color coated sheet

We mainly use PE, SMP, and PVDF three kinds of paint to produce PPGI PPGLCoil.

Coating type: polyester resin (PE), silicone-modified polyester resin (SMP), polyvinylidene fluoride (PVDF) coating performance characteristics and uses: PE board board surface and cut corrosion resistance is high, the life is generally 5-7 months, decorative in general, suitable for steel building roofs, walls and structural components; SMP coating of the color plate corrosion resistance is better than ordinary polyester products, cut corrosion resistance is high, coating life of about 10 months, decorative in general, the coating life of about 10 months, decorative in general, the color plate is better than the ordinary polyester products, cut corrosion resistance is high, the coating life of about 10 months, decorative in general, the coating life of about 10 months. SMP coated color plate has better corrosion resistance than common polyester products, high corrosion resistance against cutting, high coating life time, and general decorative properties, applicable to roof, wall and structural parts for structural buildings, steel windows and automobiles; PVDF color plate has excellent corrosion resistance, coating life time of 15-20 months, and general decorative properties, applicable to roof, wall and structural parts for structural buildings.

Package: 

Each coil to be securely tied with two bands through the eye coil and one circumferential, the contact points of these bands on the coil edge to be protect with edge protectors. Coil then to be properly wrapped with water proof/resistant paper, it then to be properly and completely metal wrapped. And each packed coil to be properly wrapped with band, three-six such band through the eye of coil at about equal distance, and two-four such bands securely tied around belly of coil at about equal distance.

Common Quality Issues：

Product wrinkles: no problem with the equipment is generally the original presence of the substrate occupies a large proportion of the hot-dip galvanized steel folds mainly from the presence of galvanized production line technology and equipment failures caused by the general understanding of the galvanizing process of the friends will not be difficult to solve this problem. 

From the appearance of the steel coil to determine the quality: the general appearance of the requirements of the winding neat, no burrs on both sides of the steel coil, jagged edges, obvious gap between the two sides of the phenomenon, this is the minimum requirements, but based on this alone is very difficult to determine the production of a variety of problems encountered. 

Holes, leakage of paint: due to defects in the quality of the substrate if the substrate has a serious edge of the broken gap, as well as the existence of holes in the substrate, then the paint staff will be in accordance with industry norms for the operation of the requirements to open the paint equipment to let it skip, which inevitably has a leakage of the phenomenon of the existence of paint.
