Abstract
The utility model relates to novel borosilicate vacuum glass which is high in production efficiency and yield, low in production cost, safe and energy-saving. The glass is structurally characterized in that two pieces of borosilicate (comprising high borosilicate, middle borosilicate and low borosilicate) flat glass are correspondingly arranged and separated by supports to form a certain gap; the four sides of the two pieces of flat glass are hot-melted and sealed to form a whole; and exhaust ports (not drawn in a figure) are reserved at corners between the two pieces of glass, and the two pieces of glass are hot-melted and sealed after being exhausted. The supports between the two pieces of borosilicate flat glass can be made of a very thin opaque material with very small diameter or a slightly thick organic transparent material with relatively large diameter, and the used borosilicate flat glass can be tempered in advance to improve strength and fulfill the aim of safety. A low-emissivity (LOW-E) film or other transparent conductive metal oxide film can be plated on the borosilicate flat glass to prevent heat rays and ultraviolet rays from permeating, and the transparent conductive metal oxide film can be plated by a sol-gel method. A layer of plastic film can be compounded on the borosilicate flat glass through a hot melt adhesive or an ultraviolet (UV) adhesive to improve the strength and safety performance of the vacuum glass.
Description
Technical field
A kind of vacuum glass, particularly a kind of take the vacuum glass of borosilicate glass as former manufacturing.
Background technology
At present, known vacuum glass all is to use the soda-lime-silica glass processing and fabricating.Its production technique is: adopt two sodium calcium silicon sheet glass with low melting glass four limits to be sealed, wherein a slice is on glass a vapor pipe, and vapor pipe and this sheet glass also seal with low melting glass.Two sheet glass gaps are 0.1 ~ 0.2 millimeter, can bear barometric point for making glass under vacuum state, are placed with small upholder between two sheet glass, and upholder is made with metal or non-metallic material and evenly distributed.Because upholder is very little, can not affect the light transmission of glass.
The problem that exists is: because the very high and surperficial easy-weathering of the coefficient of expansion of soda-lime-silica glass is moisture, when therefore being former manufacturing vacuum glass with sodium calcium silicon sheet glass, must finish edge sealing, exhaust and the sealing process of vacuum glass in High Temperature Furnaces Heating Apparatus.Inevitably like this can bring following problem: 1, production efficiency is low; 2, yield rate is not high; 3, can't directly adopt toughened glass to be made into safety vacuum glass; 4, cause unnecessary energy dissipation; 5, very small upholder needs to make with metal or non-metallic material precision, not only expensive the and difficulty that distributes; 6, for enhancing the transparency and not affecting vision, the gap of two sheet glass need be done as thin as a wafer, so, just must improve its vacuum tightness, to guarantee its effect of heat insulation.And between the soda-lime-silica glass plate, extract and keep condition of high vacuum degree, not only need high-temperature exhaust air also to need getter, so complex process, cost is higher.
Summary of the invention
For this reason, the utility model utility model provides a kind of borosilicate Novel vacuum glass, and not only production efficiency and yield rate are high, production cost is low and energy-saving safe for the vacuum glass of this structure.
Its constitutional features is: adopt the corresponding placement of two borosilicates (comprising high borosilicate, middle borosilicate and low borosilicate three classes) sheet glass, be separated with certain gap with upholder between two borosilicate sheet glass; Four limits of two borosilicate sheet glass self hot-melting sealed is integrated; Corner between two borosilicate glass is reserved with bleeding point (not shown in FIG.), and after bleeding heat-sealable closing.
Can adopt the very small and very thin opaque material of diameter, also can adopt the larger and slightly thick organic transparent material of diameter as the upholder between two borosilicate sheet glass.The borosilicate of its use (borosilicate and low borosilicate two classes especially) sheet glass is tempering in advance, to improve intensity and to reach safe purpose.
Can see through to stop hot line and ultraviolet ray at borosilicate sheet glass plating LOW-E film or other transparent conductive metal sull.This transparent conductive metal sull can adopt the collosol and gel plated film.
Also can be on borosilicate sheet glass with hot melt adhesive or the compound last layer plastic film of UV glue intensity and the safety performance in order to improve vacuum glass.
Above-mentioned hot melt adhesive can adopt PVB or EVA.
Above-mentioned plastic film can adopt BOPET.
Because borosilicate sheet glass has low thermal expansion, therefore can be directly in normal temperature environment with flame or LASER HEAT sealing by fusing limit, and can adopt the laser heat sealing.
Because therefore the not easy-weathering suction of borosilicate surface of plate glass need not high-temperature exhaust air, and the manufacturing process of vacuum glass is greatly simplified.
Compare with present known vacuum glass, the advantage of this borosilicate Novel vacuum glass is: 1, technique is simple, efficient is high, cost is low; 2, intensity is high, and is safe and reliable; 3, save the energy; 4, has better heat preservation and soundproof performance; 5, owing to can adopt transparent material to make upholder, the vacuum gap of vacuum glass can suitably be thickeied (greater than 0.2 millimeter, can be selected in 0.2 ~ 2 millimeter), is conducive to extraction and the maintenance of its vacuum tightness.
