The difference between pvc and pet
Different origins. As a PET material, PET plastic was patented in 194 1, while PVC (polyvinyl chloride) was discovered by American V. Regnaud as early as 1835. When vinyl chloride is irradiated by sunlight, it produces a white solid, that is, PVC.
1, different uses: PET plastic is suitable for electronic and electrical industries and automobile industries, and is used for various coil formers, transformers, televisions, tape recorders, automobile lamp holders, lampshades, incandescent lamp holders, relays, selenium rectifiers, etc. PVC (polyvinyl chloride) is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials and fibers.
2. Different properties: Generally, PET resin is ivory translucent or colorless transparent body, with a relative density of 1.38 and a light transmittance of 90%. PVC (polyvinyl chloride) is a white powder with amorphous structure and low branching degree, and its relative density is about 1.4.
What are the advantages and disadvantages of pvc materials
1, PVC floor Disadvantages: high requirements for construction foundation, fear of cigarette burns and sharp cuts.
2. Advantages of 2.pvc floor
Waterproof and anti-skid: the surface is of high-density special structure, imitating wood grain, which is more convergent and anti-skid when it meets water. Family paving can relieve the safety concerns of the elderly and children. Its characteristics are incomparable with stone and tile.
Super wear resistance: the wear resistance of floor materials depends on the material and thickness of the surface wear-resistant layer, not just the total thickness of its floor tiles. Brand PVC floor is covered with 0. 1-0.5 mm thick polymer special material, which has high wear resistance and the longest service life among similar brand products. Compared with the thin transparent film on the composite wood floor or the glaze on the tile, it is even worse.
Light weight: the weight after construction. After construction, it is 10 times lighter than wooden floor, 20 times lighter than ceramic tile and 25 times lighter than stone, which reduces the bearing capacity of the building, ensures safety and is convenient to carry.
Convenient construction: no need for cement and sand, no need to build trees and break ground, and special glue is used for paving, which is quick and simple. There are many kinds of products, such as slate, crushed stone, marble and wood grain, which can be assembled freely, saving time and effort, and is OK at one time.
The above contents mainly describe my differences between pvc and pet? What are the advantages and disadvantages of pvc materials? In the past two years, many materials have been developing in a good direction. So before confirming something, it will definitely help to know some details. In well-known materials, differences are bound to exist, but the specific situation depends on detailed knowledge.
