Description
Technical field
The invention belongs to glass machining techniques, are more particularly to a kind of aluminosilicate glass processing technology.
Background technology
Currently, due to not containing fluxing alkali metal oxide, and Al in ingredient2O3And SiO2Content is higher, and has
Preferable chemical stability, electrical insulating property, mechanical strength and lower coefficient of thermal expansion can be used for fabricating halogen lamp glass
Shell, alkali-free substrate, alkali-free glass fiber dimension and chemical pipeline etc..
Alkali-free aluminosilicate glass it is melted very difficult, bubble and striped in glass are not easy to exclude.This kind of glass in the country at present
The thawing of glass is all made of platinum crucible and carries out continuous smelting or single crucible production.This mode of production cost of alkali-free aluminosilicate glass significantly,
And bring larger difficulty to the forming of special-shaped such as tubing, thin slice product, cause alkali-free aluminosilicate glass with receive compared with
Big limitation.
To solve the above-mentioned problems, meet the needs of national economic development is to aluminosilicate glass kind and yield, establish scale
It is economical --- yield is provided, cost is reduced, becomes the development trend of glass applications exploitation.But scale economy is formed, first
It should solve the problems, such as the melting furnaces of large-scale production.Wave have a rest stove be the eighties France Bussy inventions one kind can it is continuous, also intermittently give birth to
The new type high temperature electric melting furnace of production.The melting furnaces are a metal can structure, and lower furnace roof is kept with the batch not being completely melt
Temperature eliminates being in direct contact for refractory material and glass metal, solves under the condition of high temperature using cold leaching state glass as pool wall liner
The erosion of refractory material and the pollution problem of glass metal.Wave has a rest stove using heated by electrodes, and stove is interior to form resistance heating area, glass metal
From the outside side reflux in center high-temperature region, centralised temperature fully meets requirement of the high-melting glass to glass melting temperature up to 2000 DEG C.State
Outer many producers have used the melting furnaces that alkali-free aluminosilicate glass is melted.
In addition to it need to solve that means are melted, to form large-scale production and need to be strengthened research to class glass technology performance, at
In the case of not introducing alkali metal oxide in point, the fusing temperature of glass is reduced by alkaline-earth metal box rare-earth oxide
Degree, adjusts the material of glass, when reducing glass smelting and forming with this, is wanted to the technology of melting furnaces, refractory material and forming technology
It asks, the glass quality to improve large-scale production creates conditions.
There is splendid high voltage performance with the glass mirror that alkali-free aluminosilicate glass is cast, be various boilers, reaction under high pressure
Kettle, petrochemical industry and the dedicated special glass of submarine.Aluminosilicate glass is a kind of pressure-resistant glass product of paricular value, it has preferableization
Stability, electrical insulating property, mechanical strength and lower coefficient of thermal expansion are learned, can be used to manufacture high pressure glass plate for levelmeter, change
Work pipeline viewing mirror, pressure vessel sight glass etc..

In some embodiments, if there are specks to adjust in time when edging, forbid with file reparation, preventing because accepting not
Cause chip.
In some embodiments, hot bending processing step is：
Compression bar is put into furnace chamber and bakes 2-5 minutes；
There is the glass on print side to be suppressed to form blanketed zone with polished rod, polished rod head needs to keep smooth, the glass packet on no print side
Cloth compression bar is suppressed to form blanketed zone, and chalk is applied on infantees；
It carries out mending powder by hand in the blanketed zone of aluminosilicate glass and four corners；
Carry out upper piece with load trolley, upper piece after check surrounding allowance it is uniform, prevent mould, hinge mouth and corner paster
The upper surface of glue, the glass of silica flour will be equably sprinkled between three pieces big or small slice and is placed on cavity plate, it is heated, when glass reaches softening
When the temperature of point, glass reaches consistent with cavity plate curvature under the action of its own gravity either external pressure, rear to stop carrying out
Heating, slowly anneals, and terminates until reaching room temperature, so far completes the process of hot bending.
In some embodiments, mode of heating when preheating glass is that laser heating is either slowly heated, and is made in stove
The temperature in face is uniform.
In some embodiments, the radius of curvature of the glass bending of two panels overlapping is identical.
In some embodiments, the cavity plate, which is horizontal, is placed on the trolley of carrying.
Advantage is：Aluminosilicate glass prepared by processing method through the invention, which can be used for yacht special glass, to be made

Specific implementation mode
With reference to specific embodiment, the present invention is further illustrated.
A kind of aluminium silicon formed glass processing technology, includes the following steps：
Cutting：Prepare aluminosilicate glass, aluminium cutter is used in combination to cut aluminosilicate glass.In cutting, pressure should not be too large, and avoid
Cause the loss of aluminosilicate glass.In this embodiment, using because of special mark's cutting machine, the pressure when cutting aluminosilicate glass is
1.8-1.9bar, speed 70% avoid causing chip in cutting.
Edging：Edging is carried out to the aluminosilicate glass by cutting using emery wheel.The pressure of edging is 6bar, cutting speed
Degree is 0-150000mm/min, and the 70% of speed is 105000mm/min.If there are specks to adjust in time when edging, forbid with file
Knife reparation prevents from causing chip because accepting unevenness.
It dusts：The diatom powder of 325 mesh and water are pressed 1：8 ratio carries out mixing to obtain mixture, will be by described in edging
Aluminosilicate glass is sent into powder case and is sprayed to the surface of the aluminosilicate glass using the mixture, spray pressure 0.4-
0.5Mpa, drying temperature are 95-105 DEG C.Powder mesh requirement evenly drying after dusting on aluminosilicate glass surface.
Hot bending：The aluminosilicate glass by dusting is preheated by slow heating or laser heating, preheating glass
When mode of heating be laser heating either be slowly heated, keep the temperature inside stove uniform.Temperature in bending furnace is adjusted to
640-710 DEG C, glass can start to start to deform under the effect of gravity.Mould is pasted according to the glass baked out during hot bending
Situation and spherical surface state correct hot bending time, temperature and stove silk watt level in time.
Hot bending handles specific steps：
Compression bar is put into furnace chamber and is baked 2-5 minutes；
There is the glass on print side to be suppressed to form blanketed zone with polished rod, polished rod head needs to keep smooth, the glass packet on no print side
Cloth compression bar is suppressed to form blanketed zone, and chalk is applied on infantees；
It carries out mending powder by hand in the blanketed zone of aluminosilicate glass and four corners；
Carry out upper piece with load trolley, upper piece after check surrounding allowance it is uniform, prevent mould, hinge mouth and corner paster
The upper surface of glue, the glass of silica flour will be equably sprinkled between three pieces big or small slice and is placed on cavity plate, it is heated, when glass reaches softening
When the temperature of point, glass reaches consistent with cavity plate curvature under the action of its own gravity either external pressure, rear to stop carrying out
Heating, slowly anneals, and terminates until reaching room temperature, so far completes the process of hot bending.It is currently luxury yacht glass one
Folder is three pieces, point big-and-middle small pieces, between big or small slice.
Wherein, when cavity plate is placed on the upper surface of trolley of carrying, it is ensured that the horizontality that cavity plate is placed.Two panels weight
The radius of curvature of folded glass bending is identical, avoids that the glass of interlayer is allowed to generate optical distortion.
