Introduction of glass protective film production

  • There are many types of glass protective film, but there are three main categories, namely dyed film, primary color film, and vacuum coated window glass film. They all have their own subordinate classifications and their own characteristics. This time we mainly introduce glass & protective films used in home decoration. home appliances protective film.

    Glass & home appliances protective film has excellent transparency, light transmission function, high chemical stability, can achieve strong mechanical strength and thermal insulation effect according to various processing methods, self-tinting glass or excess can also block light. It is used in various fields to meet various needs.

    glass protective film

    Glass protective film is coated with a layer of water-soluble adhesive and covered with a transparent protective film. During construction, it is necessary to spray water on the glass to be photographed, then tear off the transparent protective film, and spray it on the surface coated with water-soluble adhesive. Apply the construction film to the glass with an appropriate amount of water, then wipe the outer surface of the construction film with a plastic scraper. Remove air bubbles and residual moisture on the glass contact surface of pe surface protective film, and after the protective film is dried, the glass protective film can be firmly attached to the glass.

    Glass protective film is usually attached to the inside of the glass. Before applying the film, the glass must be thoroughly cleaned, and the parts to be photographed must be cleaned repeatedly. Any fine dust left on the glass will make a difference. Adhesion of glass protective film The film and the glass veneer are kept in a vacuum state and adhere firmly, so the strength and viewing angle after shooting. Before cutting the glass protector, remember to choose a horizontal or vertical cut. Vertical cuts are usually chosen because horizontal cuts do not shorten as effectively as vertical cuts. It is necessary to cover the cover, remove the keychain, mobile phone, watch, ring, etc., and use pe surface protective film to prevent scratches on the film surface or glass surface.

    In order to ensure the quality of the construction workers' work, the glass protective film workplace must be dust-free, and roadside construction is prohibited. When die-cutting glass protective film, the surface material and adhesive need to be cut together, but in theory, the die-cut paper material is a combination of knife cutting and paper force destruction, and the cutting edge will also cut the paper. Because both sides are extruded, the die-cutting accuracy of paper materials is not so high, and some labels will have burrs during sample analysis, but this is due to the phenomenon of thicker fibers of the material. And it's a natural fracture. The glass protective film is based on the die-cutting characteristics of the paper material, considering the wear of the blade, the blade angle is 52°, assuming that the blade angle is large, that is, the material is squeezed and deformed greatly, that is, identification. The lateral trend of the force exacerbates the phenomenon of material decomposition. Most film materials are durable and will not break naturally, so cutting two-thirds is inappropriate and should be cut completely. Cut out 5.4/4 thickness. Otherwise, the label will come off during disposal. The strength of the surface material of pe surface protective film is related to the thickness of the surface material, the fiber (polymer) structure, and its own humidity.

    The most important factor involved in the die-cutting process of PET protective film material. The faster the waste is discharged to the surface material, the higher the humidity, the strength of the material of glass protective film manufacturers will become weak after being damp, easy to break, and even cause an accident in serious cases.
