Polyvinyl chloride (PVC) related knowledge and common film types
For everyone's knowledge of polyvinyl chloride (PVC), what is polyvinyl chloride (PVC)? What is the performance of polyvinyl chloride (PVC)? How to apply it to injection molding?
What is polyvinyl chloride (PVC)?
Polyvinyl chloride, abbreviated as PVC, is a thermoplastic resin obtained by polymerizing vinyl chloride under the action of an initiator. Common thermoplastic materials, pcv is not flammable, and the shrinkage rate is relatively low. It is often used as a rental material for stabilizers, lubricants, auxiliary processing agents and colorants.
Products: Polyvinyl chloride (PVC) common film types
A. Ordinary PVC shed film: The film-making process does not add anti-aging batch auxiliaries. The use period is 4-6 months, which can produce one season crop, which is gradually being eliminated.
B. PVC anti-aging film: The anti-aging additive is added into the raw material to form a film by calendering. The effective use period is 8-10 months, and it has good light transmittance, heat preservation and weather resistance.
C, PVC non-drip anti-aging film: at the same time has anti-aging and dripping characteristics, light transmission and heat preservation, no dripping can be maintained for 4-6 months, safe service life of 12-18 months, widely used It is currently the most energy-efficient solar greenhouse to cover materials first.
D, PVC weather-resistant and drip-free dust-proof membrane: In addition to the characteristics of weather-resistant dripping, the surface of the film is treated, the amount of plasticizer is less, the dust is less, and the light transmittance is improved, which is more favorable for winter and spring cultivation in the solar greenhouse. .
E, PVC tree can also be used as a mulch film, adding a certain amount of color masterbatch can produce a variety of different color film
Application: Polyvinyl chloride (PVC) plastic gusset
Installation: First, the elevation line should be popped on the wall, the pressure line should be fixed at both ends of the wall, and the cement nail and the wall surface should be fixed firmly. The board is cut according to the actual size of the ceiling, and the board is inserted into the second board... The last board should be cut according to the actual size. When cutting, use a sharp cutting knife, use a steel ruler to press the elastic line to cut, and do a little while loading. Bending can be inserted into the top plate of the upper plate, and the bead seals on both sides after the installation.
If you are a practitioner in the plastics and related industries (materials, equipment, molds, products, automobiles, toys, home appliances), if you want to know about injection molding, extrusion, blow molding, calendering, rogue technology, etc., please click Zhenye Injection Molding; ID :zy-plas is off.
Maintenance: PVC ceiling type has strong water and scrub resistance. After daily use, it can be scrubbed with a cleaning agent and clean water.
Cleaning; the gap between the plates is easily contaminated by oil stains. After cleaning, brush with a cleaning agent and brush with clean water; pay attention to the lighting circuit.
Quality appraisal: When purchasing PVC ceiling profiles, you must ask the dealer for quality inspection report and product inspection certificate. Visual inspection of the quality of the board surface should be smooth and smooth, no cracks, no bumps, can be assembled and disassembled freely, the surface is shiny, no scratches; the surface of the board is smooth by hand. In the inspection test report, the product performance indicators should meet: heat shrinkage rate less than 0.3%, oxygen index greater than 35%, softening temperature above 80 degrees Celsius, ignition point above 300 degrees Celsius, water absorption rate less than 15%, moisture absorption rate less than 4%.
Problems and solutions in the application of PVC profile protection film
Problems and solutions in the application of PVC profile protection film
The PVC profile protective film is made of a plastic film or an aluminum-plastic composite material, and is coated with a low-viscosity pressure-sensitive adhesive on one side, and is formed into a roll after being cut into a roll. Sticking to the surface of the profile can effectively prevent the surface of the profile from being scratched or contaminated during extrusion, transportation, windowing and installation. Its appearance has brought great convenience to profile production, door and window assembly, and construction units. Since the profile protection film is a relatively new type of product, there is currently no national or industry standard.
Brief introduction and application of PVC wood grain film
Brief introduction and application of PVC wood grain film
PVC wood grain film is made of natural color texture of wood such as oak, eucalyptus, ash, salabil, walnut, maple, pine, mahogany, rosewood, etc. PVC is printed on the substrate and compounded. High-grade decorative mask! Natural color, gorgeous colors, rich patterns, elegant style, and very suitable for interior doors, wardrobes, ceilings, walls and other surface decoration. At the same time, PVC decorative film has the advantages of moisture proof, anti-corrosion, flame retardant, easy to clean, easy to install, green and environmental protection!
PVC embossed film thickness 0.1-3.0mm, plus a variety of different embossing, to create a variety of unique style. There is a sense of crystal flicker, alternating layers of bright fog, good transparency and high brightness; widely used in mouse pads, writing pads, curtains, sandals, slippers, sports shoes, shoe covers, mobile phone sets, transparent belts, stationery pencil cases, Eye boxes, handbags, children's backpacks, cosmetic bags, wallets, handbags, food bags, shopping bags, etc.
Today's pvc embossing film industry, product homogenization competition is a common phenomenon. The pvc film manufacturer's decorative film is self-adhesive and non-adhesive. It can be applied to a variety of wood boards (such as plywood, high-density board, wood board, etc.) and other materials (such as high-pressure cement board, asbestos board). Surfaces of metal sheets, automobiles, refrigerators, air conditioners, ships, trains, glass, aluminum and steel profiles. The newly adopted process uses a vacuum laminating machine and a line coating machine to firmly adhere the PVC decorative film to the surface of the substrate. This process is widely used throughout the country, making furniture manufacturing, interior decoration, and hand-appliing processes easy for factory process operations. , improve production efficiency and benefit human life!
