Inspecting and cleaning the glass panel. The method for raising intensity of the glass panel on the portable electronic device, can effectively shorten reinforcement time of the glass panel, can raise reinforcement efficiency, and can reduce usage cost.
Description
Technical field
The present invention relates to improve the method for the intensity of portable type electronic product upper glass panel, chemical enhanced by in a series of stages utilizes a series of ion-exchanges, and glass anti-impact force intensity can improve.
Background technology
Traditionally, the equipment of little shape-dependent constant, for example hand-held electronic equipment has the demonstration that comprises various layers and arranges, shows and arranges based on the technique of display layer.The covering window of little shape-dependent constant equipment, perhaps face glass can have plastics or glass to make.Plastics are durable, but easily by scratch.The glass scratch resistance, but frangible.Substantially, glass is thicker, and then it is firmer.But unfortunately, glass cover is usually thinner, and may be parts weak in the device structure, and is especially all the more so in its edge.For example, when portable electric appts was subject to the stress of improper mode, face glass can easily be damaged.The chemical enhanced reinforced glass panel that has been used to.Even now usually work is good, but still there is lasting demand in the mode that the reinforced glass panel is provided.
Summary of the invention
Present invention relates in general to improve the intensity of face glass.Change the surface composition of glass according to the mechanism of ion diffusion, at a certain temperature glass is immersed in the high-temperature molten salt, mutual exchange occurs because of diffusion in the alkalimetal ion in the glass and the alkalimetal ion in the fused salt, produce " jammed " phenomenon, make glass surface produce stress under compression, thereby improve the intensity of glass.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of method that improves the face glass intensity on the portable electric appts is provided, and the first, raw material cutting: according to predetermined size cutting raw material; The second, sharp processing: face glass is processed into predetermined shape; The 3rd, the first reinforcement: place face glass the first forced fluid to be heated to 435 ℃, constant temperature 4 hours; The 4th, circulating cooling: the face glass after will strengthening places water coolant to cool off; The 5th, secondary hardening: cooled face glass is dipped in and is warming up to 435 ℃ in the second forced fluid, and constant temperature 3 hours enters water cooling afterwards; The 6th, clean: the inspection face glass also cleans up.
Preferably, adopt CNC that face glass is processed in the described second step sharp processing, give the face glass edge specific geometric shape.
Preferably, the first forced fluid that uses in first reinforcement of described the 3rd step is saltpetre and silicon dioxde solution.
Preferably, water coolant needs in advance heating in described the 4th step circulating cooling.
Preferably, the second forced fluid in described the 5th step secondary hardening is saltpetre, aluminium sesquioxide and sodium hydroxide solution.
The invention has the beneficial effects as follows: a kind of method that improves the face glass intensity on the portable electric appts of the present invention, can effectively shorten the enhanced time of face glass, promote and strengthen efficient, reduce use cost.And by the face glass that the inventive method is strengthened, its surface impact is stronger, and the anti-bending strength of glass is better, and physical strength is high, and has certain thermostability.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1 is the schematic top plan view of face glass;
Fig. 2 is raw-material structural representation;
Each component names is as follows in the accompanying drawing: 1, raw material; 2, fillet; 3, face glass.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1 and Fig. 2, the embodiment of the invention comprises: a kind of method that improves the face glass intensity on the portable electric appts:
1. with raw material 1 cutting, singly be divided into the face glass 2 of a plurality of predetermined sizes, and clean product examine, afterwards gone to next worker station non-defective unit week;
2. glass surface 2 plates are carried out the CNC sharp processing, form the face glass edge corresponding to specific prespecified geometric and enhanced squeezing in the chemical enhanced edge annex that can make face glass 2 is provided.Can make face glass firmer by giving the specific prespecified geometric in face glass edge thus.In CNC implemented, edge geometry was configured to reduce or level and smooth sharp keen transformation, for example is processed as fillet 3.After sharp processing is finished product is cleaned product examine, go in week and strengthen the worker station.
3. get the worker product of standing, face glass 2 is placed strengthen in the frame, put on the reinforcement stove that adds the first forced fluid, carry out preheating, the first forced fluid is saltpetre and silicon dioxde solution.Warm up time 10Min, 435 ℃ of preheating temperatures, not preheating is directly put into and can be made the easy embrittlement of glass in the forced fluid, also can affect strengthening effect, preferably makes the glass preheating temperature approach strengthen temperature.Enhanced time 4H strengthens 435 ℃ of temperature.
4. go up a station strengthen finish after, face glass 2 is taken out from strengthening in the stove, putting into recirculated water lowers the temperature, will be in preheating oven when coming out of the stove cooling down slowly, can not directly take out glass, otherwise glass also can embrittlement, preferably first burned the water temperature of tank, take away more soaked, guarantee that the saltpetre dissolving is complete, carry out product examine through washing after platform cleans again.
5. the face glass 2 that product examine is good places and strengthens in the frame, is placed on the reinforcement stove that adds the second forced fluid, carries out preheating, warm up time 10Min, 435 ℃ of preheating temperatures, enhanced time 3H strengthens 435 ℃ of temperature.After reinforcement is finished, face glass is taken out from strengthening in the stove, put into recirculated water, guarantee that the saltpetre dissolving is complete, non-defective unit is had enough to meet the need next worker station.
6. at last the face glass 2 after strengthening is well checked, guarantee the full surface leakless, packing warehouse-in through washing after platform cleans.
A kind of method that improves the face glass intensity on the portable electric appts of the present invention can effectively shorten the enhanced time of face glass, promotes to strengthen efficient, reduces use cost.And by the face glass that the inventive method is strengthened, its surface impact is stronger, and the anti-bending strength of glass is better, and physical strength is high, and has certain thermostability.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
