Description of the drawings
Fig. 1 is the flow chart of the manufacturing method provided in an embodiment of the present invention for reducing tempered glass stress pattern.
Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, a kind of manufacturing method for reducing tempered glass stress pattern provided in an embodiment of the present invention, it is intended to solve
By the tempered glass that traditional tempered glass producing method obtains there are the defects of stress pattern is apparent, poor flatness, so as to lead
It causes after use, deformation of image is serious from outdoor, influences visual effect, generates serious light pollution, manufacturing method packet
It includes：
Selection trimming process：Original sheet glass is chosen, and according to production requirement, cutting process is carried out to original sheet glass.It is selecting
It takes in the process of original sheet glass, pay attention to the color of original sheet glass, thickness, date of manufacture, size and pulls side effect etc..
Wash grinder sequence：Edging is carried out, and clean original sheet glass to original sheet glass.When washing mill processing, scuffing, water are paid attention to
Print, chip, quick-fried angle, situations such as dimensional discrepancy and edging are bad, with ensure original sheet glass heated before product quality,
Improve yields.
Heating treatment step：The original sheet glass obtained by washing grinder sequence is delivered in annealing furnace and is heated,
Wherein the heating temperature of annealing furnace is maintained in the range of 570~700 DEG C；And according to the thickness of the original sheet glass heated,
It is persistently heated according to the heating time parameter of 60~120 seconds/millimeter, it is ensured that original sheet glass can be heated evenly, and glass is whole
Body deformation is non-warping, ensure that the flatness of original sheet glass, and light pollution is improved during use.
Tempering treatment process：The original sheet glass obtained by heating treatment step is exported rapidly from annealing furnace, and anxious
Speed is cooled to room temperature, wherein during cooling, ensures that glass air grid outlet air is uniform, production is made to obtain tempered glass stress pattern
Small, be invisible to the naked eye stress pattern, and tempering (half tempered) glass product can significantly improve tempered glass appearance.
In tempered glass production field, tempering (half tempered) glass be annealed glass after glass softening point is heated to
Glass surface is unified to blow, and glass is made to cool down the principle of making rapidly.For there are the tempered glass of stress, it also has single shaft
The optical property of crystal, all uniaxial crystals may be divided into both positive and negative, the speed of light extra ordinary ray when through glass
Degree, which reduces, is known as positive crystal, and light speed of extra ordinary ray when through glass, which increases, is known as negative crystal, by uniform compression
Glass has the characteristics of negative sense uniaxial crystal in polarized light microscopy Microscopic observation, by the glass of uniform tensile stress, then has positive uniaxial brilliant
The characteristics of body.
And in the toughening process of glass, the target that we lay siege to is to be obtained on the thickness direction of glass reasonably
Stress distribution, i.e. surface are compression, and centre is tensile stress.But in fact, the compression on tempered glass surface is in whole surface
On there are stress distribution it is uneven the phenomenon that, it is this it is uneven will lead to birefringence in this direction, and birefringent presence, and making
It is incident on the ordinary beam of visible ray among glass, extra ordinary ray is returning glass surface by the reflection on second surface
When, optical path difference is formed with incident light, forms composite wave.It is known that if phase difference is not integer wavelength, nor two/
One odd-multiple, the amplitude of light wave will change, and generate cancellation or enhancing, form the speckle that light and shade intersects, that is, I
The stress pattern seen.Stress pattern formed it is rear we be with the naked eye observed that on glass there is light and dark striped (to present color
Color strip-shaped), more obvious after glass superposition, it is the inherent shortcoming of tempered glass, and observing image outside glass chamber significantly distorts change
Shape, the appearance of serious image cladding glass visually generate uncomfortable image sense, the beauty of image building.
The present invention implements the manufacturing method of reduction tempered glass stress pattern provided, and grinder sequence is washed by selection trimming, right
Original sheet glass carries out processing early period and prepares, it is ensured that the quality of heating front glass original piece.Meanwhile in heating treatment step, root
According to production requirement, by heating and temperature control between 570~700 DEG C, and according to the thickness of original sheet glass, according to 60~120 seconds/
The heating time parameter of millimeter persistently heats original sheet glass, mainly controls glass flatness to adjust tempering temperature
(waveform and arch) and image and stress pattern problem, so as to while ensure that production efficiency, original sheet glass be enable to be heated
Uniformly, glass overall deformation is non-warping, ensure that the flatness of original sheet glass, and light pollution is improved during use, carries
The high quality of product.Available for the processing of the compound product such as monolithic, interlayer, hollow, plated film, more meet customer need.
Specifically, according to conditions such as the type of different glass original piece, thickness, the heating temperature range control of annealing furnace is existed
600~670 DEG C.And in the present embodiment, heating temperature is 650 DEG C, and the original sheet glass efficiency of heating surface is high.
Specifically, according to conditions such as the type of original sheet glass, thickness, heating time parameter area is set as 80~100
Second/millimeter.And in the present embodiment, it is 90 seconds/millimeter by heating time parameter setting, so as to ensure that original sheet glass can be by
Hot uniformity, glass is integrally non-warping, ensure that the flatness of original sheet glass.
The embodiment of the present invention additionally provides a kind of tempered glass, by the manufacturing method of above-mentioned reduction tempered glass stress pattern
It obtains.By using the tempered glass that above-mentioned manufacturing method produces, image is observed outside the tempered glass room that this temperature, time produce
Indeformable, flatness is preferable, and in outdoor observation, the deformation of edge effect is slight, and water ripples are with the naked eye observed with glass into 45 degree of angles
Do not go out, observation overall image effect is indeformable, and stress pattern, which is visually seen, to be loseed, and so as to avoid the generation of light pollution, is reached
A kind of visual effect of beauty, meets the expectation that client increasingly increases tempered glass quality
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modification, equivalent replacement or improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
