Description
Technical field
The relevant a kind of physical toughened glass of the application's case, especially a kind of thin thickness, and have the physical toughened glass of good mechanical properties, thermostability and transmittance, it can be used in opticglass, vehicle glass, building glass, ambetti and the aeronautical glasses, particularly solar panel.
Background technology
Toughened glass is called again chilled glass, has preferably mechanical properties and thermostability than general glass.Whether the tensile strength (tensile strength) of general common annealing glass is about 40MPa, and toughened glass is about 120 to 200MPa, depending on thickness, the Edge Finish of glass, hole or grooving and different.Toughened glass is exactly the tensile strength that has increased glass.If glass is processed through tempering in advance, then can allow 150 to 200 ℃ temperature head, also increased security simultaneously, therefore be widely used in each field.
Toughened glass is sheet glass, and such as the secondary processing product of float glass or annealed glass, it is to utilize physics or chemical process, forms a compressive stress layer at glass surface, forms a tension stress layer at inside glass simultaneously.When glass was subject to External Force Acting, this compressive stress layer can with the payment of part tension stress, be avoided the cracked of glass.Even the local generation of glass is damaged, then stress relief can occur, so that the countless fritters that glass breaking becomes not have sharp corners, be difficult for hurting sb.'s feelings.
Toughened glass can be divided into physical toughened glass and chemically toughened glass because of the processing mode difference.
Physical toughened glass is called again quenching toughened glass, it is that general sheet glass is cut into required size, carry out edging or boring, then be placed on the roller table, push the softening temperature (about 600 to 650 ℃) that is heated in the annealing furnace near glass, eliminate internal stress by the deformation of glass self, then glass sliding is gone out annealing furnace, with the bull nozzle cold high pressure air is blowed to the two sides of glass again, make it rapidly and be cooled to equably room temperature.After the cooling, can cause stress at glass surface, and inside glass forms tension stress, thereby reach the purpose that improves strength of glass.Because this kind tempering mode does not change the chemical constitution of glass, therefore be called physical toughened glass.
High about 3 to 5 times of the general glass of the strength ratio of physical toughened glass, and processing procedure is simple, expense is cheap, and long service life can reach the time about 20 years usually, is the present toughened glass of normal use on the market.But because the mode that heats by the roller table limits, the thickness of physical toughened glass needs more than 3 millimeters, just can not cause the distortion of glass.Yet as the glass that uses is too thick, with increasing the own wt of product, not only increases hauled weight, as using at top of building or roof surface, weight is born in increasing, causes the restriction in the use.In addition, the thicker transmittance of thickness of glass is then poorer.
Chemically toughened glass is the intensity that improves glass by the chemical constitution that changes glass surface, generally is that the methods such as application surface dealkalize or alkalimetal ion exchange process are carried out tempering.The chemical tempering mode has changed the contained composition of glass surface, so that glass produces very large carrying capacity, its effect and physical toughened category of glass are seemingly.
Strong about 9 to 15 times of the general glass of the strength ratio of chemically toughened glass, and without the upward restriction of thickness of processing.Yet chemically toughened glass is easy to because environmental factors damages, and follow-uply films difficultly, produce easily stripping phenomenon, so work-ing life is shorter, and usually only less than 10 years, and expense is higher, causes the restriction in the use.
In view of this, the present invention's research and development achievement of namely doing for foregoing problems.This case contriver finds to come toughened glass with the Aerodynamic Heating mode, can make thinner physical toughened glass, and does not affect or very can promote mechanical properties, thermostability and the transmittance of toughened glass, to meet the industry demand.
