PVC board is a kind of board. So what is PVC board? I believe many friends don’t know. Let’s learn about the relevant content of PVC board.
What is PVC sheet?
The English full name of PVC is the abbreviation of polyvinylchloride (PVC molecular structure). Generally speaking, our common PVC is a kind of plastic decoration material. Its chemical name is polyvinyl chloride. It is composed of an amorphous thermoplastic resin made by polymerization of vinyl chloride monomer and certain additives (such as stabilizers, lubricants, fillers, etc.). It has mechanical properties, strong acid and salt resistance, and low softening point. Chemical properties are stable. It is often used to make sheets, wires, cable insulation, seals and other items.
The essence of PVC is a vacuum plastic-absorbing film, which is used for surface packaging of various types of panels. Therefore, it is also called decorative film and adhesive film. It is used in many industries such as building materials, packaging, medicine, etc. Among them, the building materials industry accounts for the largest proportion, 60%, followed by the packaging industry, and several other small-scale application industries.
PVC is also called polyvinyl chloride. The density of pure PVC is 1.4g/cm?, and the density of PVC plastic parts with plasticizers and fillers added is average. is 1.15-2.00g/cm?. Rigid polyvinyl chloride has good tensile, bending, compression and impact resistance, and can be used alone as a structural material. The softness, elongation at break, and cold resistance of soft PVC will increase, but the brittleness, hardness, and tensile strength will decrease. PVC has good electrical insulation properties, can be used as low-frequency insulation material, and its chemical stability is also good. Due to the poor thermal stability of polyvinyl chloride, long-term heating will cause decomposition, release of HCL gas, and discoloration of polyvinyl chloride. Therefore, its application range is narrow, and the use temperature is generally between -15 and 55 degrees.
Types and characteristics of PVC boards
There are many types of PVC boards, and different types of PVC boards have different characteristics. Let’s take a look at their specific differences:
p>
1. PVC transparent board. It is a plastic sheet produced using high-grade imported raw materials. PVC transparent sheet has the characteristics of high strength, good transparency, non-toxic and clean, and good weather resistance. We often use it for indoor decoration, drinking water tanks, etc. .
2. PVC soft board. This kind of sheet is a kind of rolled material. It comes in various colors, including green, gray, brown, etc. The surface of the sheet is shiny, the texture is soft, and it has excellent properties such as wear resistance, acid resistance, cold resistance, and tear resistance. It is often used for interior decoration of trains and cars.
3. PVC welding rod. The general specifications of this kind of plate are 1.5 to 3 mm wide and 1000 mm long. They are divided into double roots and single roots. Welding technology is often used during construction.
4. PVC plastic board. This kind of plate is a thermoformed plastic with good corrosion resistance. It is often used to replace stainless steel and other corrosion-resistant materials. Therefore, it is often used in chemical industry, petroleum, environmental protection equipment, electronics, etc. decoration.
5. Hardness PVC board. This kind of board is produced using the world's most advanced CM80 conical twin-screw extrusion production line. It generally comes in two colors: white and gray. It has very strong stability, corrosion resistance, high strength, aging resistance, and flame retardancy. It has the characteristics of good sex, not easy to absorb water, not easy to deform, and easy to process. Its appearance is also very beautiful and elegant, and it is often used in many environmentally friendly decorations.
PVC board uses
1. PVC board transparent board is produced with high-grade raw materials as auxiliary materials. PVC transparent sheets in various colors such as white, brown, royal blue, etc. This kind of PVC sheet is mainly used in interior decoration, instrument liquid level display and equipment guard panels.
2. PVC sheets are divided into soft and hard ones, and soft PVC sheets have a soft surface. Available in a variety of colors at the same time. It requires the use of high-quality raw materials and fine production. It is the first choice raw material for train and automobile interior decoration. Can also be used for insulating underlayment. It is a very good auxiliary material.
3. PVC board is also a high-quality plastic board. Its function can also replace some stainless steel and some corrosion-resistant synthetic materials. PVC sheet materials are widely used in chemical processing equipment and environmental protection equipment. PVC sheets are also used in decoration and communication industries.
The chemical properties of hardness PVC sheets are relatively stable. It has many excellent properties, such as corrosion resistance, insulation, UV protection and is strong and hard. PVC sheets have a smooth surface and are not easily deformed. Can be used in multiple industries.
The softer PVC sheets require more effort in the materials used. The production is also very detailed. It is more common to be used as interior decoration. It has excellent weldability, and the PVC sheet is also wear-resistant and acid-resistant. At the same time, the physical properties are by no means inferior to other rubber products, and are even better than these products.
