    There are roughly two types of PVC film in the market now:

    The first kind: PVC film its production method is a layer of colored PVC film directly printed on the wood grain grain, the production process is completed, the production is simple, its use method is to spray blister (water-based) on the decorative surface, and then the PVC blister film is directly laid on the door panel, push the vacuum suction machine, at a certain temperature, suck up for about a minute, you can be out of the oven, trimming can be.

    The disadvantage is that it is easy to peel and blister after a long time, and it can only be used as an interior door.

    The second kind: PVC transfer film, the composition is polyvinyl chloride, its production is more technical, its film has a detached layer between the ink, it is also sprayed on the door panel, the PVC film is spread on the door panel, at a certain temperature for about a minute, after the temperature drops, directly tear off the PVC film, the wood grain is left on the door panel, and then get to the paint room, do the primer topcoat.

    The disadvantage is that it is a little more expensive than the above film, and there are many advantages, it is lightfast, which can be used for outdoor use, and it does not peel and blister.

    What I learned about this film is Jiaozuo Zhuoya Art Film Technology ****, and the process is still very mature, ** can also, I know a number here, 15938177936, it seems that the surname Jiao, if you need to, you can contact him, my friend is now using the door factory.

    The problem of glue can be the problem that the raw material content of the door panel is enough, and the door panel should be glued after the dry film is just finished.

    1. The ingredients are different.

    Polyurethane material is the abbreviation of polyurethane, which is a polymer material. Polyurethane is an emerging organic polymer material, known as the "fifth largest plastic", and is widely used in many fields of the national economy because of its excellent performance.

    Polyvinyl chloride, known as PVC in English, is the initiator of vinyl chloride monomer in peroxides, azo compounds, etc.; or polymers polymerized under the action of light and heat according to the reaction mechanism of free radical polymerization. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively known as vinyl chloride resins.

    2. The characteristics are different.

    Polyurethane soles offer a number of advantages: low density, soft texture, comfortable and lightweight to wear; Good dimensional stability and long storage life; Excellent abrasion resistance and flexural resistance; Excellent shock absorption and anti-cracking and slippery performance; Good temperature resistance; Good chemical resistance and much more. Polyurethane is mostly used in the manufacture of high-end leather shoes, sports shoes, travel shoes, etc.

    The molecular weight of industrially produced PVC is generally in the range of 50,000 to 110,000, with large polydispersity, and the molecular weight increases with the decrease of polymerization temperature. There is no fixed melting point, 80 85 begins to soften, 130 becomes viscoelastic, 160 180 begins to transform into viscofluid; It has good mechanical properties, tensile strength of about 60MPa, impact strength of 5 10kJ m2; It has excellent dielectric properties.

    3. Different uses.

    Polyurethane materials are widely used in clothing, shoemaking, luggage, furniture, sports and other industries. All the areas of leather application, it can be replaced, but also can be applied to the field of leather can not be applied, the dermis is very susceptible to the influence of animals (cattle, sheep, pigs, etc., mad cow disease).

    PVC used to be the world's most produced general-purpose plastic and has a wide range of applications. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc.

    PVC is a vinyl polymeric substance, and its material is an amorphous material. PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, pigments, impact inhibitors and other additives in practical use. It has non-flammability, high strength, resistance to climate changes and excellent geometric stability.

    PVC is highly resistant to oxidants, reducing agents, and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.

    Polyurethane is a polymer material. It is widely used in daily life, such as paints and coatings in furniture, refrigerators and freezers in household appliances, roof waterproofing and insulation and interior and exterior wall coatings in the construction industry, etc. It can also be made into various polyurethane materials such as polyurethane soles, polyurethane fibers, polyurethane sealants, etc.

    In general, the performance of polyurethane products can be adjusted in a wide range, with strong adaptability, biological aging resistance, and moderate performance.

PVC electrostatic film is characterized by being firm but not solid, sticking firmly to the surface of various substrates, and when it is removed at the end of the process, there will be no gum residue and no corrosive effect. Different varieties of products, its moisture resistance, aging resistance is slightly different, electrostatic film is a kind of non-adhesive film, mainly PE, PVC material, relying on the product itself electrostatic adsorption to adhere to the protective role of the item, generally used for adhesive or glue residue sensitive to the surface, mostly used in glass, lenses, high-gloss plastic surface, acrylic and other very smooth surface. The electrostatic film does not feel static electricity outside the film, it is a self-adhesive film, the adhesion is low, and it is enough to be used on the bright surface, and the general thickness is 3 wires, 5 wires, and 8 wires. >>>More
