If you want to invest in PVC exterior wall hanging board machinery and equipment, you have to take a good look at this informationWe need to play different roles in life, and I am also trying to do my best. And the poems and distant places that rely on the end of the world are still dreaming. There are always days, hand in hand with the one you love.
When I was at home these days, I answered a phone call from an old friend and asked about the Qiangka production line. Let's talk about the next blog. Today, let me talk about the exterior wall hanging panels.
What I read in Baidu Encyclopedia is this description? From the architectural point of view, the exterior wall hanging board is a construction technology. The board is hung on the outside of the wall by dry hanging and other methods to achieve the effects of decoration and heat preservation. From the product level, the external wall hanging board is a kind of building material, which is applied to the building material of the external wall. The outer wall is different from the inner wall. The outer wall must have the basic properties of anti-corrosion, high temperature resistance, anti-aging, no radiation, fire prevention and no deformation. At the same time, it also needs to be beautiful, heat preservation, environmental protection and simple construction. At present, the more popular ones on the market are fiber cement board, aluminum composite board, PVC exterior wall hanging board and stone and so on.
Today, I will just talk about the production process, technical requirements and other related information of PVC exterior wall siding. If you have considerations in this regard, please read carefully.
1. Raw materials: The difference between the exterior wall hanging board and the interior wall decoration board is that it needs functions such as radiation resistance, high temperature resistance, ultraviolet ray resistance, and aging, which has higher requirements for materials. PVC exterior wall hanging board can be understood in this way. It is divided into two layers. The top is the co-extruded layer with ASA material (has good mechanical and physical properties, strong weather resistance, anti-aging ability is more than 10 times that of ABS, high temperature resistance, anti-static And other properties), the following is PVC with calcium powder, stabilizer, stearic acid, paraffin and other synthetic materials.
2. Process: ASA is a granular object, which can be co-extruded with a single screw. The base material is PVC composite, it needs to mix all kinds of raw materials and mix them evenly to remove the moisture. The mixed materials are automatically transported to the twin-screw main engine through the feeder, and the raw materials are plasticized by heating, and the mold is a sheet co-extrusion mold. The ASA and PVC base materials come out of the mold at the same time, and the wood grain pattern is embossed, shaped, punched, pulled, cut, and the material table accepts the finished product. The whole process is actually quite complicated. They are all profiles, but there are more embossing machines than wallboards and other profiles. Online punching machines. Of course, all are automated and mechanized, although cumbersome but no labor is required. The external wall hanging board is relatively thin, and the requirements for the equipment are relatively higher. We have much experience in this area, so-called practice makes perfect.
3. Requirements for the production of PVC exterior wall panels: First, the issue of environmental impact assessment. You must first consult with the local industrial and commercial department, make a formal process, step by step, and standardize production. The workshop usually requires a length of more than 50 meters and a width of more than 20 meters. This is not absolute, depending on the production capacity requirements. We need you to fully communicate with our external wall hanging board machinery and equipment manufacturers, provide the site plan, and design the best plan. If you need a matching power supply, if you look at several production lines, you will generally require an independent transformer of more than 160 customers. Water is recycled. Make a pool in a convenient place outside of the workshop, so that it is not wasted for recycling.
4. Others: There are many molds and shapes for external wall hanging boards, which belong to a series of products, so the production line is estimated to be more than three or two. With so many molds, it is not a small investment project.
