Description
Technical field
The present invention relates to the preparation method of air strengthened glass in glass post-processing field.
Background technology
Wind tempering technology refers to the glass strengthening technology that ordinary plate glass use intensity is improved by heat treatment process.
Air strengthened glass intensity is 2~3 times of simple glass intensity, and good impact resistance, heat endurance is good, is hit in external force
Hit down do not allow it is broken；Even if broken, internal tensile stress makes whole glass moment be broken into tiny particle, bearing stress
Then fine particle is pressed together, larger fragment will not be formed, avoid injury of the glass fragment to human body, therefore air hardening steel
Glass belongs to safety glass, in architectural extensive use.
The content of the invention
, can it is an object of the invention to provide one kind in order to solve defect present in above-mentioned existing wind tempering technology
Heating has the coated glass of heat reflection, reduces roller print and abrades, improves the flatness reduction table after flat glass tempering
The preparation method of the air strengthened glass of surface damage degree.
To achieve these goals, the technical solution adopted by the present invention is as follows：A kind of preparation method of air strengthened glass,
Realized by following steps：1) glass load through roller-way be sent into heating chamber step, 2) heating stepses, 3) cooling step, 4) unloading piece step
Suddenly；It is characterized in that：The heating chamber inner chamber is at least divided into 4 sections, the outlet of the heating chamber porch and each bringing-up section
Place is respectively mounted the hermatic door with control device；The heating-up temperature of the heating chamber inner chamber is arranged to 290-720 DEG C, by it is low to
Height is distributed in each bringing-up section, and the temperature between previous bringing-up section and latter bringing-up section is trapezoidal incremental, and its temperature difference is 100-
150 DEG C, every section of heat time is respectively set to 100~300 seconds；The glass unidirectionally uninterruptedly moves forward with the roller-way, its
Translational speed is 20~100mm/ seconds；The cooling step uses cold wind blower, and cool time is 180~600 seconds.
Setting up separately for above-mentioned bringing-up section can have various ways, one：4 bringing-up sections can be divided into, the 1st, 2,3 section is adopted
With electric furnace heating wire radiant heating；4th section is heated using convective air circulation；Its every section heating-up temperature is respectively set to：1st section
290-310℃；2nd section 440-460 DEG C；3rd section 540-560 DEG C；4th section 680 DEG C.
Secondly：4 bringing-up sections can be divided into, at least 1 section is heated using convective air circulation in the 1st, 2,3 section, and remaining is adopted
With electric furnace heating wire radiant heating；4th section is heated using convective air circulation；The heating-up temperature is respectively set to：1st section of 290-
310℃；2nd section 440-460 DEG C；3rd section 560 DEG C；4th section 680-720 DEG C.
Thirdly：4 bringing-up sections can be divided into, convective air circulation mode of heating is respectively adopted in 4 bringing-up sections；Every section
Heating-up temperature be respectively set to：1st section 290-310 DEG C；2nd section 440-460 DEG C；3rd section 540-560 DEG C；4th section is
680-700℃。
According to the specification size and quality requirement to safety glass, according to above-mentioned mode of heating, bringing-up section can also divide
Multistage is set to, heating-up temperature is scattered in multiple independent bringing-up sections, to ensure the safety glass surface quality processed not
It is damaged.
Above-mentioned cold wind blower uses slit injector air grid type cold wind blower.
The present invention general principle be：
1. changing the mode of heating of a greenhouse heating in traditional safety glass technology, heated using the glass of a Room multi-temperature section
Technology, the thermal shock of the 290-720 DEG C of heating temperature difference is distributed in 4 or more bringing-up sections, glass is in previous heating
It is pre-heated in section and enters back into the latter bringing-up section after design temperature and continue to heat, thermal shock is small, and glass deformation is small, glass
Weight is undertaken by more rollers, can mitigate the scratch for even completely eliminating roller to glass back significantly.
2. the mode in rotary moving of glass in traditional safety glass technology with roller-way " positive-reversely-positive " is changed,
Using by glass in heating process unidirectional continual move mode, make glass keep a direction constant motion, the back side
The frictional force size and Orientation being subject to is constant, reduces glass deformation degree and surface damage degree；
3. heating glass by the way of hot-air convection heating, the glass of heating will not be by the shadow of glass surface membranous layer property
Ring, uniformly can quickly heat the various coated glasses such as Low-E, realize the tempering of coated glass.
4. using slit cooling air grid technology cooling glass, by the point cooling side of traditional circular hole formula air port
Formula makes the wire type type of cooling of slit type air spray line into, improves the uniformity to heating glass cooling, effectively reduces glass
The defects of glass surface stress difference, improve the flatness of glass surface.
The present invention is after adopting the above technical scheme, have the beneficial effect that：(1) add in improved wind steel process
Convective air circulation mode of heating is entered, has realized the air hardening steel to the various coated glasses such as Low-E, effectively increase Low-E
Etc. the intensity of various coated glasses；(2) heating chamber is divided into some bringing-up sections, is divided into 4 sections or more of section, by 290-720 DEG C
Temperature be divided into 4 or multiple temperature layers by the temperature difference, will piecewise elevated Temperature Distribution in each bringing-up section, enable glass
It is enough that another higher temperature range is steadily being entered by a temperature range, the heat acclimation power of glass is stepped up, it is real
The purpose that its existing air strengthened glass flatness is high, deformation is small；In the cladding glass of composition, image fault is small, and presentation quality shows
Write and improve；(3) cooling device uses slit injector air grid type cold wind blower, is dried by slit type air and sprays line
Wire type cools down, and improves the uniformity of glass surface cooling, makes its glass surface stress through air hardening steel uniform, stress speckle
Degree mitigates 50%, even completely eliminates；(4) as a result of improved glass mode of heating, move mode and new cooling
The integration technology of mode, solve safety glass unsolved problem always for a long time, be not only able to produce ordinary flat
Safety glass, and can also the various coated glasses of tempering, glass flatness, optical quality after tempering improve, roller print and should
Power speckle is reduced and even completely eliminated；Technique is simple and convenient to operate, implementation easy to spread.
