Abstract
A Low-E glass sandwich technology is disclosed. LOW-E glass and another piece of glass are placed in an up-down position. The upper layer is LOW-E glass, the upper surface of which is provided with a Low-E film. A layer of PVB film is placed between the two layers of glass. The spacing between upper press rolls of a preheating prepress is set as 10.2 mm, and the spacing between lower press rolls is set as 9.3 mm. Pressure of the preheating prepress is set as 0.7 Mpa. In the first stage of preheating prepressing, heating temperature of the upper and lower pieces of glass is set as 80 DEG C; in the second stage of preheating prepressing, heating temperature of the upper LOW-E glass is set as 190 DEG C, and heating temperature of the lower glass is set as 170 DEG C; and in the third stage of preheating prepressing, heating temperature of the upper LOW-E glass is set as 200 DEG C, and heating temperature of the lower glass is set as 180 DEG C. transfer speed is set as 0.55 m/min. By a servo-link, the upper and lower pieces of glass synchronized. According to the invention, cohesiveness between PVB and glass can be improved, damage to the film surface is prevented, and then production process can be simplified and quality of the product can be enhanced.
Description
Technical field
The present invention relates to the production technology of laminated glass, specifically a kind of Low-E glass sandwich skill
Art.
Background technology
Current laminated glass for building be by two panels or two panels more than simple glass PVB glue
Sheet process is heated, pressurizeing to cohere forms, and PVB film is firm with glassy bond, its energy penetration,
Security performance is good, and shielding of ultraviolet and reduction noise, be a kind of excellent safety glass.Low spoke
Penetrate glass (i.e. Low-E glass) and also widely apply due to its excellent heat preservation and insulation
Architectural, but existing Low-E glass receives all technique in terms of deep processing examines
Test and limit, such as make Low-E preheating glass precompressed time low-radiation film be difficult to heating and
Absorption heat is uneven, causes glass to be particularly easy to broken and Low-E glass-film surface damage, causes
Product power saving function declines and presentation quality is defective.It addition, preheat precompressed time Low emissivity
Film is difficult to heating, and PVB is poor with glass portion bonding, causes laminated glass product defective, produces
Rate is low.And in terms of cold working, accidentally will produce scuffing, arrisdefect, collapse the phenomenons such as limit,
Also needing pasting protective film, cause processing technique to become complicated and loaded down with trivial details, the most slightly flaw becomes at once
Become waste product, owing to Low-E glass is expensive, thus cause heavy losses.
Summary of the invention
For above-mentioned problems of the prior art, it is desirable to provide a kind of Low-E glass
Glass sandwich technique, by the LOW-E glass after tempering or half tempered and another sheet tempering or half tempered
Glass (can be the glass kind meeting laminated glass GB9962 1999 standard) relatively put
Putting, upper strata is LOW-E glass, and the upper surface of LOW-E glass is provided with Low-E film, two-layer glass
One layer of PVB film is put in the middle of glass；The upper roller space of preheating preformer is set as 10.2mm, will be pre-
The lower compression roller spacing of hot preformer is set as 9.3mm, is set as by the pressure of preheating preformer
0.7Mpa。
It is characterized in that, the first stage of preheating precompressed, LOW-E glass above and following glass
The heating-up temperature of glass is all set as 80 degree；The second stage of preheating precompressed, LOW-E glass above
Glass is set as 190 degree, and the heating-up temperature of glass below is set as 170 degree；The of preheating precompressed
In three stages, LOW-E glass above is set as 200 degree, and the heating-up temperature of glass below sets
It it is 180 degree.
Transfer rate is set as 0.55m/min, uses servodrive, synchronizes up and down,
Prevent face from damaging.
By LOW-E glass above and following glass heating-up temperature are controlled respectively, top
Temperature is higher than temperature of lower, reduces temperature, speed, the most uniformly heating, to meet product matter
Amount.
The present invention is controlled respectively by top and the bottom heating-up temperature, and upper temp is higher than temperature of lower,
Reduce temperature, speed, slowly uniformly heating such that it is able to improve PVB and glass portion caking property,
Prevent face from damaging, and then production technology can be simplified, improve product quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Reference: 1,6mm Low-E glass 2, PVB film 3,6mm glass
4, Low-E film
Detailed description of the invention
In order to make it easy to understand, below by embodiment, in conjunction with accompanying drawing, the technical side to the present invention
Case is further described in detail:
As it is shown in figure 1, a kind of Low-E glass sandwich technology, by the 6mm after tempering or half tempered
LOW-E glass 1 (can be to meet interlayer glass with the 6mm glass 2 of another sheet tempering or half tempered
The glass kind of glass GB9962 1999 standard) staggered relatively, upper strata is LOW-E glass 1,
Lower floor is glass 2, and the upper surface of LOW-E glass 1 is provided with Low-E film 4, in the middle of layer glass
Put into one layer of PVB film 3；The upper roller space of preheating preformer is set as 10.2mm, by pre-for preheating
The lower compression roller spacing of press is set as 9.3mm, and the pressure of preheating preformer is set as 0.7Mpa.
The first stage of preheating precompressed, 6mm LOW-E glass 1 above and following 6mm glass
The heating-up temperature of glass 2 is all set as 80 degree；
The second stage of preheating precompressed, 6mm LOW-E glass 1 above is set as 190 degree, under
The heating-up temperature of the 6mm glass 2 in face is set as 170 degree；
The phase III of preheating precompressed, 6mm LOW-E glass 1 above is set as 200 degree,
The heating-up temperature of following 6mm glass 2 is set as 180 degree；
Transfer rate is set as 0.55m/min, uses servodrive, synchronize up and down,
Prevent face from damaging.
By 6mm LOW-E glass 1 above and following 6mm glass 2 heating-up temperature are divided
Not controlling, upper temp is higher than temperature of lower, reduces temperature, speed, the most uniformly heating,
To meet product quality.
Above-described embodiment is the illustration to technical solution of the present invention or explanation, and should not manage
Solve as the restriction to technical solution of the present invention, it is clear that those skilled in the art can be to the present invention
Carry out various modifications and variations without departing from the spirit and scope of the present invention.If these amendment and
Modification belongs within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention also comprises
Including these amendments and modification.
