Introduction of PVC plastic board, classification, function and use

Publisher: PP board |pvc board |pe board | polypropylene plate | polyethylene plate

PVC board - point of view

PVC plate, so PVC is made of extruded plastic sheet as material. Most of the plain, grey, red.

PVC board - brief introduction

PVC board: polyvinyl chloride (PVC) plastic is a polymer made of vinyl chloride monomer polymerized by free radical. The English name is polyviny chloride, or PVC.

PVC can be divided into soft PVC and hard PVC. The hard PVC accounts for about 2/3 of the market and soft PVC accounts for 1/3. The original color of PVC is a vacuum plastic film, which is used for the surface packing of various panels. It is also known as decorative film and adhesive film. It is used in many industries, such as Yu Jiancai, packaging, medicine and so on. The largest proportion of building materials industry is 60%, followed by the packaging industry, and a few other small-scale industries.

Soft PVC is usually used in the surface of the floor, ceiling and leather, but because soft PVC contains tender agent, it is easy to become brittle and not easily retained, so it is used in the scope of its use. Hard PVC contains no softener, good flexibility, easy molding, no crispy, no poison and no pollution, and keeps the time. Therefore, it has great cost of opening up.

PVC foam board has the characteristics of anticorrosion, moistureproof, mildew proof, non water absorption, drillability, sawing, planing, easy to heat forming, hot zigzag processing and so on. So it is widely used in furniture, cabinet, bath cabinet, box core, interior and exterior decoration, building materials, chemical and other categories. Computer engraving, electronic instrument product packaging and other industries.

PVC hard plastic plate has excellent corrosion resistance, insulation, and a certain machine strength; after two processing, it can be made into sulfuric acid (hydrochloric acid) trough (bucket box), public toilet tank, processing product template, decorative plate, exhaust pipe, equipment lining and other special-shaped finished products, containers and so on. It is material of aspiration and choice for chemical industry, building materials, decoration and other industries.

In the early period of 60, second were retreated. Because PVC resin is rich and cheap, demand is increasing rapidly, and its location is increasing. General PVC uniform degree of polymerization of 500~~150 and PVC type high degree uniform degree of polymerization is more than 1700. Our commonly used PVC resins are universal.

PVC board - function

As usual, PVC resin is a red or yellowish powder with an absolute density of 1.35-1.45. The soft and hard level of finished products can be stopped by taking part in the number of plasticizers. Pure PVC has little water absorption and permeability.

Mechanical function PVC has higher hardness and mechanical function. It increases with the increase of molecular weight, but decreases with the decrease of temperature. Rigid PVC has good mechanical properties and its elastic modulus can reach 1500-3000MPa. The elastic 1.5-15 MPa of the soft PVC. But the elongation at break is up to 200%-450%. The attrition of PVC is just the same. Static friction is 0.4-0.5, and the coefficient of dynamic friction is 0.23.

The thermal stability of PVC is very poor. It starts to differentiate at 140, and the melting temperature is 160 degrees. The linear expansion coefficient of PVC is small, and has high flammability. The oxidation index is higher than 45.

The electrical function PVC is a kind of polymer with good electrical properties, but because of its polarity, the electrical insulation is not as good as PP and PE. Dielectric constant, dielectric consumption angle tangent and volume resistivity are large, and corona resistance is not good enough, which is usually suitable for medium high voltage and low frequency insulation data.

Situation of function PVC resistant to most inorganic acid, alkali and salt, most organic solvents. Appropriate medicine, chemical anticorrosion materials.

PVC board - scale

1, tell the white industry -- screen printing, engraving, advertising signs, exhibition boards, marking boards.

2, furniture industry bathroom furniture, all kinds of high-grade furniture board.

3, building decoration industry - building exterior wall board, interior decoration board, room, office, public building partition, commercial decoration frame, dust free room board and ceiling board.

4, transportation industry -- steamship, aircraft, passenger cars, train carriages, canopy, box core and external decorative panels.

5, industrial use, chemical industry, anti-corrosion engineering, thermoforming parts, cold store boards, special cooling engineering and environmental protection boards.

6, other uses -- templates, sports equipment, breeding materials, coastal waterproofing measures, water resistant materials, art materials, all kinds of simple partitions.

PVC board - Layout

PVC, the full name is Polyvinylchlorid, and its main component is polyvinyl chloride. Others take part in other components to enhance its heat resistance, toughness and ductility. The most basic type of these exterior coatings is lacquer, the most important part is polyvinyl chloride, and the most basic is the back coating adhesive. The material can produce a three-dimensional mask, PVC is the most appropriate information.

PVC board - market prospect

PVC can be seen everywhere in the daily life of people. PVC can not only express the color of nature, but also express the color of people's ambition. In Germany, 40% of furniture is made from PVC for external information, such as desks, bookshelves, sofa, kitchen cabinets, etc. It is a differentiated material that is popular and popular nowadays in the world. It is the universal usage in various differentiation material in the second. According to statistics, in 1995 alone, the amount of PVC produced in Europe is five million tons, while its consumption is five million and three hundred thousand tons. In Germany, the production and consumption of one million and four hundred thousand tons of uniform PVC. PVC is a 4% growth rate in the world within the scope of production and use for. The number of growth in Southeast Asia is particularly evident.
