The pet in Chinese means polyterephthalic plastic, everyday called polyester.The raw material of PET is polyester, the main components are butyl acetate PBT resin and terephthalate PET, which form PET through the high temperature extrusion of the machine.
The pet material is an environmentally friendly material with bright color, small color difference, strong visual stereo, no cracking and little collapse in processing, white series, frosted black series, wood series, no discoloration, pressure resistance, touch resistance, high temperature resistance, corrosion resistance, aging resistance, easy cleaning.
The pet film covering plate is made of metal materials such as steel plate as the substrate. After the substrate surface is degreased and chemical treatment, a layer of PET film and a layer of metal plate are combined through high temperature and high pressure.In terms of performance, the PET steel plate not only has the processing and forming performance of metal materials, but also the PET materials through the surface can also have corrosion resistance, pollution resistance, acid and alkali resistance and other protective properties.
So now I share with you the role of pet film plates of different substrates
1. Hot-plated galvanized steel plate
The zinc content of the hot galvanized (Q195, SPCC, DC01) substrate is generally 180g / m2 (double-sided), and the hot galvanized substrate outside the building is 275g / m2. Hot galvanized PET coated plate in addition to zinc protection of PET protective effect, the surface also plays the role of isolation protection, prevent rust, service life is longer than hot galvanized plate, outstanding impact function and outstanding extension rate and yield value, the coated steel plate made of this base plate is generally used in construction, decoration and other industries.
2. Hot-plated aluminum-galvanized steel plate
Aluminized galvanized steel plate (55%AI-Zn and 5%AI-Zn, brand number DC51D + AZ, DC52D + AZ, S250GD + AZ) as the substrate has light, beautiful and good corrosion resistance, and can be directly processed, and the process of hot galvanized steel plate is basically similar, the difference is in the zinc layer composition on the surface, surface zinc phenomenon is very different, other aspects basically no gap, weather resistance and life is better than galvanized steel plate.
3. Aluminum board
Aluminum plate (plate number 1060,3003,3004,5052) as the substrate is generally used in special industries, because the price of aluminum plate itself is very high, so only special industry options: refrigeration, warm, anti-virus and other industries.Impact performance: excellent, can be tangible, invisible impact, bending.
4. Cold rolling plate
Cold-rolled plates are unannealed steel plates and the predecessor of galvanized and aluminum-galvanized steel plates.This steel plate has a very low impact function, a very high material hardness, and the yield value and extension rate are very low.Although the coated steel sheet with the cold rolled substrate has the processing performance of the cold rolled plate, the PET material is scratched to expose the cold rolled substrate to the air, thus quickly producing red rust at the exposed iron place.Therefore, such products can only be used for undemanding temporary isolation measures and for indoor materials.
The advantages of pet coated plates are:
1. Anti-lampblack: easy to clean.
2. Wear resistance: unique PET layer, strong and durable.
3. Anti-moisture: the surface is coated with film, reducing the direct contact between water and aluminum, and has strong durability.
4. Good touch: there is a film on the surface, and the touch is smooth, changing the cold and single feeling of the metal material.
5. Many colors: available from a variety of colors.
6. Moderate price, good cost performance.
The substrate of pet film cover plate can be selected according to customer requirements, with a thickness of 0.3-1.0mm, and a color customized according to customer needs, and their application field will also be different. Therefore, we must find the right positioning when using it.
