(3), after the precooling that utilizes vacuum pump to carry out earlier 28～32 minutes from the vacuum bag air outlet vacuumizes, put into process furnace;
(4), utilize vacuum pump vacuum bag to be evacuated to negative pressure 0.09-0.1Mpa from the vacuum bag air outlet, get rid of the air between laminated glass and the doubling, be heated to 90-150 ℃ gradually by 35-40 ℃ heat-up rate per hour,, make doubling have certain viscous force;
(5), keep constant temperature, stop to vacuumize and keeping vacuum tightness;
(6), reduce to normal temperature, reach traditional technology roll-in → same technique effect of heating → roll-in, unload lower-glass and vacuumize bag;
(7), send in the autoclave to steam and press, special-shaped sandwich glass.
Another purpose of the present invention also is to provide a kind of glass that is made of double-deck PE coextrusion nylon film bag to vacuumize bag, and it is in the centre on compound membrane bag surface or a valve is set all around, and valve one end exposes and is that it is inlet mouth that air outlet, the other end place in the compound membrane bag.
Further technical measures are, in stating, valve is made of the Non-return air valve of top tracheae, lower end nut and valve bottom, be equipped with air cushion between nut and the compound membrane bag, air cushion is placed in the nut thread place and is higher than nut, and the outside of valve and compound membrane bag junction is sealed by bilateral sealing-ring with inboard.
The present invention compared with prior art, application glass vacuumizes bag and carries out the deep processing of special-shaped sandwich glass, the simple precompressed warm that solves irregular complex construction, material cost vacuumizes material well below tradition, and through the production application of Guangzhou Hing Wah Glass Industry Co., Ltd.'s splinter-proof glass, yield rate reaches more than 99%.
The present invention has following technical superiority with the technology of utilizing silica gel strip surrounding edge and silica gel bag to vacuumize processing in the past:
1, cost of manufacture is low, and the material cost is low, and former cost of manufacture is 100 yuan, and then the used cost of the present invention only needs 2 yuan, saves 98% technology cost, significantly reduces cost, and increases economic efficiency;
2, technological process is few unproductive time, and is convenient to use, produces easily the production efficiency height;
3, use glass and vacuumize bag and carry out the preheating precompressed of special-shaped sandwich glass, do not damage glass surface, protect effective;
4, use and to vacuumize bag glass in the bag is intercepted with extraneous, secluding air and dust guarantee the smooth finish and the degree of cleaning of glass, the glass quality height of making, and also glass vacuumizes bag and is disposable environmental protection material type, avoids secondary pollution;
5, can be widely used in being particularly useful for the making of step glass, splinter-proof glass in the industries such as building, automobile and industry, not only adapt to the production technique of special-shaped sandwich glass, and may extend in the middle of the production application of other sandwiched product.
