Rapid glass method for adhering film
Technical field
The present invention relates to glass technology field, particularly relate to a kind of rapid glass method for adhering film utilizing liquid or solid state medium.
Background technology
In order to reduce the light transmittance of glass or in order to play protection glass and improve the needs of strength of glass, often at the film on surface of glass, the pad pasting mode being generally adopted has manual pad pasting and machinery pad pasting two ways. Adhering film to glass is generally to spray one layer of masking liquid on surface, it is simple to film can move adjustment position on glass, improves pad pasting quality. It is well known that the moisture that the masking liquid that present adhering film to glass adopts contains is higher, adopts nature to dry or adopt heat dehydrator to carry out drying moisture to it, but the whole drying cycle is all long, affect production efficiency, and bubble easily occurs, affect pad pasting quality; The intensity of glass can be produced impact by the drying mode of heat dehydrator, reduces the service life of glass.
Summary of the invention
Based on this, it is necessary to for traditional rapid glass method for adhering film Problems existing, it is provided that a kind of efficiently, do not have the rapid glass method for adhering film of bubble, high-quality.
A kind of rapid glass method for adhering film, comprises the steps:
First step: cleaning complete with water by the dirt on the glass treating pad pasting, the described glass then treating pad pasting is dried process;

Third step: cleaning on the complete described glass treating pad pasting, described film one layer of volatile liquid of even application respectively on the surface of described glass;
4th step: described film is placed in and treats on the described glass of pad pasting and drag adjustment position gently;
5th step: smooth running roller carries out rolling process on the described glass complete pad pasting with generating heat.
Wherein in an embodiment, described volatile liquid is ethanol or ether.
Wherein in an embodiment, when described volatile liquid is ethanol, this alcohol concentration is more than 99%.
Wherein in an embodiment, the surface temperature of described smooth running roller is 5 DEG C��80 DEG C.
Wherein in an embodiment, the surface temperature of described smooth running roller is 30 DEG C��50 DEG C.
Wherein in an embodiment, the rolling speed of described smooth running roller is 1��8 m/min.
Wherein in an embodiment, the time that described rolling processes is 1��60 second.
Wherein in an embodiment, also include:
6th step: the described glass after rolling is processed carries out key performance detection, it is desirable to overlay film surface reaches light, smooth, no wrinkle, bubble-free etc.;
7th step: the described glass that pad pasting is up to standard is carried out protection packing processes.
A kind of rapid glass method for adhering film, comprises the steps:
First step: cleaning complete with water by the dirt on the glass treating pad pasting, the described glass then treating pad pasting is dried process;
Second step: take out stand-by film, tears the protective layer of described film off;
Third step: cleaning on the complete described glass treating pad pasting, described film one layer of dry ice of even application respectively on the surface of described glass;
4th step: described film is placed in and treats on the described glass of pad pasting and drag adjustment position gently;
5th step: smooth running roller carries out rolling process on the described glass complete pad pasting with generating heat.
Wherein in an embodiment, the surface temperature of described smooth running roller is 5 DEG C��80 DEG C, and the rolling speed of described smooth running roller is 1��8 m/min; The time that described rolling processes is 1��60 second.
Above-mentioned rapid glass method for adhering film, at surface one layer of dry ice of uniform application respectively or the one layer of volatile liquid of spraying for the treatment of that the glass of pad pasting contacts with film; Dry ice or volatile liquid can play the masking liquid used in traditional glass pad pasting, and the viscosity reducing film when dry ice starts can move adjustment position on glass, and dry ice melts evaporation at normal temperatures afterwards, recovers viscosity and completes pad pasting; Volatile liquid plays the effect of isolating membrane when starting, liquid has quickly volatilized pad pasting afterwards. Owing to dry ice and liquid automatically can quickly volatilize from periphery because of the physical characteristic of self and will not produce the globule between film and glass, serve nature and dry the effect with heat drying machine drying, decrease technique, decrease process time, improve pad pasting efficiency. Film extruding ground is increased its temperature by smooth running roller simultaneously, accelerates dry ice and the peritropous evaporation rate of liquid, has also squeezed out the bubble of the inside, further increased pad pasting efficiency and pad pasting quality.
Glass after processing due to rolling carries out key performance detection, further ensures the quality of adhering film to glass, improves qualification rate.
