The Prepainted Aluminum Zinc Steel Coil are mainly made of color coated rolls. Before the next steel plate is installed, each color coated board must be completely fixed. Fixing must begin at the center of the color-coated board to prevent moisture from being stored, and then stretch to both sides. Finally, the lap joint of the fixed-coated board has become a new type of building material that is becoming more and more popular.

Prepainted Aluminum Zinc Steel Coil
(3) High Weather Resistant Polyester (HDP, High durable Polyster)
For the shortcomings of PE and SMP, HYDRO (now acquired by BASF) and BECKER of Sweden developed a 60-80% weatherable HDP polyester coating that can achieve PVDF coating in early 2000, and is superior to ordinary silicon modification. The polyester coating has an outdoor weather resistance of 15 years.
The high weathering polyester resin is synthesized by using a monomer containing a cyclohexane structure to achieve flexibility, weather resistance and cost balance of the resin, and the aromatic-free polyol and polybasic acid are used to reduce the absorption of UV light by the resin. To achieve high weather resistance of the coating.
UV coatings and hindered amines (HALS) are added to the coating formulation to improve the weather resistance of the film. High weathering polyester coil coatings have been recognized in the market abroad, and the cost performance of this coating is very prominent.
▲ Applicable industry
Metallurgical and power industry non-ferrous metal smelters (copper, zinc, aluminum, lead, etc.) are the most challenging years of use of color plates. Steel plants, power plants, etc. will also produce corrosive media, and have high corrosion resistance requirements for color plates.
Product Display
When the Prepainted Aluminum Zinc Steel Coil is stored in a damp, the surface of the plate is changed, causing scratches and paint defects during the pressing. The surface of the board can be epoxy self-flowing floor or advanced wear-resistant plastic floor. If it has anti-static requirements, anti-static type can be used.
Prepainted Aluminum Zinc Steel Coil
In addition to the protective effect of zinc on the Prepainted Aluminum Zinc Steel Coil, the organic coating on the surface of the plate also protects against rust in the storage process, and the service life of the color-coated plate is longer than that of the hot-dip galvanized sheet. For the construction industry, which is mainly used for roof walls and doors of steel structures, airports, warehouses and frozen industries and trade buildings, civil buildings use less Prepainted Aluminum Zinc Steel Coil.
Packaging&Delivery
The chemical cleaning solution used in the Prepainted Aluminum Zinc Steel Coil production line is basically composed of a complexing agent, a surfactant, sodium hydroxide, potassium hydroxide, polyphosphoric acid and the like, and is an alkaline solution. The effect of clearing the grease depends mainly on the concentration of the cleaning solution, the temperature, and the cleaning time of the steel strip. Care must be taken to control the concentration and temperature of the cleaning fluid during the cleaning process. If the concentration of the cleaning solution is too low, the surface of the substrate is not cleaned, resulting in defects in the subsequent coating treatment and affecting the quality of the coating. If the concentration is too high, the zinc and aluminum in the galvanized sheet belong to an amphoteric metal, and zinc in the hot alkaline solution. The surface of the aluminum layer is prone to form a heart acid salt, causing severe corrosion, thereby affecting the subsequent chemical coating effect.
