Some of the aluminum plate used misunderstanding
As the aluminum plate optimistic about the market in recent years there have been a lot of inferior aluminum plate caused the quality of many of the incidents resulted in no small loss. Some common quality problems include: aluminum sheet thinning is a very common problem APCP to a large extent by the strength of aluminum sheet to bear the consequences of thin aluminum sheet, on the strength of the product is very low and easy to shape and even endanger the Personal safety. The home plate is sold by weight, so a lot of manufacturers are desperate to reduce the thickness of aluminum sheet in order to increase the length of the volume of aluminum in order to reduce costs. Interior wall panels will be used on the external walls of the aluminum plate wall panels should be rust-proof aluminum, the surface of paint should be internationally recognized anti-aging properties of the best Futan Qi, in order to ensure that products in the outdoor sun and rain have long-term Life. However, some of the walls when the wall board by board, and some non-Futan Qi Fu Tanqi posing a serious shortening product life, causing unnecessary economic losses. Bubble gum product in the open surface of the product can be clearly observed bubbling sheet or off, are used in a period after. More reasons, such as bonding is not strong, contaminated raw materials, the use of poor-quality raw materials, production processes into the bubble, and so on, affect the appearance of the product and the use of security. The core issue of selection of core material of aluminum-plastic composites are currently used instead of PVC polyethylene, polyvinyl chloride because burner at the time would have fatal strongly of gas, it has not been used in China. Some manufacturers use complex constituents expected to recover, without strict sorting and handling, more impurities, the quality of the product unstable. The bonding material selection problem is difficult because of polyethylene and aluminum bonding directly, so used to be a bonding layer, which is commonly used at present a special plastic film, the film has a dual character, one with aluminum metal bonding, On the other side with adhesive polyethylene. Aluminum bonding with the surface of the need to import materials, and expensive, so if mixed to make false, it will cause a negative composite products. In addition, individual manufacturers to adopt low-grade adhesive glue for the glue to facilitate the brushing often have to glue to add some organic diluent, which was closed in the thinner sheet with the core material, hard to completely volatile, the impact on the one hand, bonding Performance, on the other hand, indoor air pollution can cause certain.
  A very modern style, rich colors, a new type of light, durable and decorative material is rapidly into our lives, and this is the mid-1990s before the rapid rise of a new generation of walls and decorative materials ------- APCP.
