Qinghai indoor convex shape Fluorocarbon aluminum veneer

Aluminum veneer and aluminum plate metal plate curtain wall application comparison have decades of history, is still used include aluminum veneer, aluminum composite panel and aluminum honeycomb panels of three. In these three materials, the most commonly used is aluminum veneer and aluminum plate. Aluminum veneer appears first, and later in the late 1960s and early 1970s, APCP invented in Germany, and quickly popular around the world. Aluminum panels and aluminum veneer in the end what is the difference? Here I am two materials to make a simple comparison: First, the cost of materials and general use 2-4mm thick aluminum veneer of pure aluminum AA1100 or AA3003 aluminum alloy sheet, general domestic use 2.5mm thick AA3003 aluminum alloy sheet ; APCP generally use 3-4mm three-tier structure, including the upper and lower sandwiching two 0.5mm PVC or PE. We can see from the material, certainly more than the cost of APCP aluminum veneer to be much lower. The current market is about 4mm thick composite panels than 2.5mm thick lower price 120 yuan / square feet or more, a Articles of a project, using the aluminum plate aluminum veneer lower than, the cost of 1.2 million yuan . Second, the process is currently the world's aluminum veneer fluorocarbon aluminum veneer spray painted in two-and-roll, the country had no stick coating line, so here veneer processing mainly about fluorocarbon coating production. Spraying aluminum veneer production is divided into two steps: The first step is sheet metal processing. This process is mainly through the flat after cutting, folding, bending arc, welding, grinding and other processes, the aluminum veneer is processed into the shape and size desired construction. The second step is spraying. Spraying is in the processed sheet metal spray paint. Spraying divided into two, one is the artificial spray, one is machine spraying. Spraying machines generally only suitable for flat rule, but this aluminum sheet used in the actual use is relatively small, artificial spraying most of the domestic manufacturers to adopt. Artificial spraying is a dangerous job, because the paint volatility and toxicity than the strong, it is easy to cause chronic benzene poisoning series, seriously affecting people's health. One big advantage is that regardless of the amount of artificial spray size, color can be optional, and aluminum plate roll coating must reach a certain amount before they can be processed. Processing aluminum plate aluminum veneer than complex, there is mainly formation, coating, composite and trimming four step process in addition to four other trimming is automated production. As can be seen from the process, aluminum panels occupy a certain advantage in terms of environmental protection and safety. Coupled with simple aluminum veneer sheet metal processing process, some private workshops began to get involved seriously affect the stability of market quality aluminum veneer.
