Aluminum magnesium manganese plate processing and production process

The external surface treatment of aluminum materials includes: two types of natural unpainted products and painted products: 1. Non-painted products: hammered aluminum alloy plates (regular patterns), embossed plates (physical means through mechanical embossing) , forming a regular pattern); pre-passivation alumina surface treatment board. Such products do not have to be painted on the surface of the board, and the appearance of the surface is not high and the price is low. 2, paint products: According to the coating process is divided into: spray plate products and pre-roller coating;

According to the type of paint can be divided into: Polyester, polyurethane, polyamide, modified silicone, epoxy resin, fluorocarbon, etc., to extend the paint as long as possible under the influence of sunlight UV, including PVDF paint The (fluorocarbon coating) has the best anti-aging properties. It is currently the strongest organic compound known to UV rays. Fluorocarbon-coated aluminum sheet, based on different quality requirements, uses horizontal automatic two-coating, two-baking, three-coating, three-coating, and four-coating and four-roller baking. The pre-coating PVDF coating has a resin content of 70%-80%. In the high-speed continuous unit on the chemical pretreatment, the initial coating, fine coating and other process roller coating, the front coating is generally 25μm, back coating anti-corrosion paint.
