People’s pursuit of environmentally friendly homes has led to the emergence of a lot of environmentally friendly building materials. Today I will mainly talk about environmentally friendly plastic boards. Plastic boards are light in texture, have good penetration, sound insulation and are easy to install. Loved by everyone. Plastic veneer decorative panels are made of special base paper and resin, and can imitate the patterns of various man-made and natural materials during the manufacturing process. Today we will take a look at the types of plastic decorative boards and purchasing tips!
What are the types of plastic decorative boards?
1. Plastic-metal composite panel
A new material that combines the characteristics of plastic and metal - "metal plastic" has been successfully developed by Chinese scientists recently. Experts say that "metal plastics" have important application value and research in many fields and can be used as nano- and micro-machining and multi-faceted excellent materials that can make auto parts as cheap as plastics in the future. It has a corrugated shape and is often used as roofing and siding panels. It mainly includes wave and arc forms of trapezoidal cross-section.
2. Rigid PVC building panels
Rigid PVC extrusion table Cincinnati Meera Crown Company imported from Austria has the world's most advanced flat CM80 conical twin-screw extrusion production line. First-class product quality, the general colors are gray and white, and colored PVC hard boards can also be made according to customer needs. The colors are bright and beautiful. Its shape is a heterosexual board. At the same time, it is also called corrugated board or side board. It is mainly used as suspended ceiling and wall board.
3. Polyethylene low-foaming calcium plastic board
Polystyrene foam is based on polystyrene resin, with additives such as foaming agent added. It is currently the most commonly used buffer. Material. Closed cell structure, low water absorption, good water resistance, low density, generally 0.015~0.03; high mechanical strength, good buffering performance, good processability, easy to form, good coloring, strong temperature adaptability, radiation resistance The advantages, and high dimensional accuracy, unified structure. Its shape is like a sandwich wall panel, which is mainly used as a thermal insulation layer on roofs and walls. It is because it has the basic properties that a wall should have.
4. Polyurethane foam board
Polyurethane foam board is made of polyether or polyester and isocyanate as the main raw materials, with flame retardants, stabilizers, foaming agents, etc. added. Mixing and stirring produce chemical reactions, and the foam formed is a new type of low-temperature insulation material. The closed pores have high porosity and low water absorption. Polyurethane foam is widely used in sandwich panels, insulated cars, refrigeration, grain storage, roof insulation, building insulation and other purposes.
Tips for purchasing plastic decorative boards
1. First of all, when purchasing, pay attention to whether the manufacturer's name, address, and trademark are complete. Because only plates with complete markings can get the quality assurance they deserve.
2. No obvious flaws on the surface. The surface of the board should be smooth and clean, free of burrs, grooves, planer marks, glue penetration, and no local yellowing, blackening or other contamination on the board surface.
3. Distinguish between artificial and natural veneers. Usually, the texture of artificial thin wood single-plate veneer is basically straight texture, and the texture pattern is regular; while the natural wooden single-plate veneer has natural wood pattern, the texture pattern is natural and irregular, and the variability is relatively large.
4. No glue opening. Glue and strength fully reflect the quality of the board's bonding performance. The higher the bonding strength value, the better the bonding performance. When selecting boards, you should pay attention to the stable structure of the adhesive layer of the decorative board and no glue opening. Observe carefully, there should be no bulging or delamination between the surface single plate and the base material, or between the layers inside the base material.
5. The smell should be light. The adhesive used in decorative boards is mainly urea-formaldehyde resin. After the decorative boards are processed, a small amount of formaldehyde will be left in the material and gradually released. This smell is extremely harmful to the human body. When purchasing, you can judge by the smell, because the greater the smell, the higher the formaldehyde release, the more severe the pollution, and the greater the hazard.
6. Pay attention to the moisture content. Usually decorative single-plate veneer plywood requires a certain moisture content. The closer its moisture content is to the equilibrium moisture content of the area of ??use, the better. If the moisture content is too high or too low, the decorative board will undergo greater deformation under the influence of ambient temperature changes.
The textures of the panels and parquet should be arranged according to certain rules, and the wood color should be similar without obvious color difference. The seams and the edges of the panels should be nearly parallel. Such boards can achieve good decorative effects. The above is the type of plastic decorative panels and purchasing tips that the editor will introduce to you today. This ends here.
