PET sheet extrusion surface pretreatment method
in order to advance the surface of PET sheet extrusion function, to improve the printing adaptability and the adhesion strength of the vacuum aluminum plating layer, along with corona treatment method to thin film surface tension. Corona method, however, some problems such as timeliness, especially in the environment of high temperature, high humidity, film tension is simple attenuation after corona treatment. Chemical coating law there is no such problem, however, is like by printing and aluminium plating. Domestic enterprises have declared open PET chemical coating series products: such as water-soluble polymer coating, can forward the surface tension of the PET sheet extrusion; Use acrylic ester emulsion coating, can improve the adaptability of printing ( Can use water-soluble ink) ; Choose aqueous polyurethane coating, can strengthen the adhesion strength of the aluminized layer with PET film roll, and can add aluminized layer thickness. Else, choose coating method can also be made antistatic and high separation membranes, etc.
PC film is polycarbonate ( Polycarbonate) Short for thin film, it is a kind of amorphous and odourless, non-toxic, highly transparent colorless or yellowish thermoplastic engineering plastics.
PC film with physical mechanical function, especially excellent impact resistance, high tensile strength, bending strength, contraction strength; Has good heat resistance and low temperature resistance, in a wider temperature range has the safe mechanical function, standard of safe sex, electric utility and the flame retardancy, can be in - Long-term use under 60 ~ 120 ℃; No obvious melting point, in 220 - 230 ℃ in molten state; Big rigidity, resin melt viscosity; Bibulous rate is small, small shrinkage, creep, high precision standard, the standard safe sex good, membrane permeability is small; Self-extinguishing data; Light, but not resistant to ultraviolet light, good weatherability; They can withstand oil, acid.
PC film poor wear resistance, solvent resistance, alkali resistance, oxidizing acid, ketone and amine, soluble in chlorinated hydrocarbons and aromatic solvents.
PC film is divided into: halogen-free flame retardant PC, black, transparent, flame retardant PC, flame retardant PC frosted PC, hard transparent PC, PC, scratch-resistant flowers PC, PC, scratch-resistant levels printing PC, optical PC
we use PC film and sheet first as follows:
1, flame retardant PC film used as insulation power system insulation, disk drives, keyboard, TV/monitor insulation insulation, computer main board insulation. Widely used in electronic components, electrical shell, switch panel, junction box and charger shell, automobile instrument and there is a requirement for flame retardant panel printing, etc.
2, printing frosted PC film is suitable for the special printing, helmets, signs, nameplate, shield, etc.
3, scratch-resistant flowers PC film use: mobile phones, MP3, MP4, DVD, electronic products, such as the back light window lens
pet plastic sheet manufacturers are required in the manufacture of almost every product and pet plastic sheet manufacturers pet sheet is one of the most common machines.
