Description
Technical field
The invention belongs to tempered glass processing technique fields, and in particular to a kind of hydrothermal pretreatment method of tempered glass.
Background technology
With the rapid development of the national economy, architectural decoration has also obtained rapid development, and tempered glass is with it
With the outstanding Special safety such as high mechanical strength, thermal stability is good, broken fragment is small, the sharp sharp wedge angle of careless nothing
Property, one of the building material product as skyscraper door and window indispensability, is widely used in building, building materials and ornaments field；To carry
The intensity of high glass forms compression usually using method physically or chemically in glass surface, when glass bears external force first
Skin stress is offset, to improve bearing capacity, reinforcing glass itself crushing resistance, cold and heat and impact；To Na2O-CaO-
Si2Temperature is at 620 DEG C -640 DEG C for O systems glass, and in the humidity province inside holding certain time, then quenching, reaches room
Surface forms the compressive stress layer of high uniformity when warm, most general at present to increase its intensity in outer force effect and thermal shocking
Logical method is heated with heater circuit, and heating time is long in heating furnace for glass, and then leads to the heating work(of heater circuit
Rate is bigger than normal, energy consumption is higher, in order to solve the problems, such as that glass heating time is long or equipment energy consumption is excessive, typically now uses glass
The technologies such as radiation forced convection heat transfer, multistation heating in annealing furnace, carry effect it is energy-efficient under the premise of, avoid glass in tempering
Fryer phenomenon in stove, to solve production cost, but preheating temperature will usually be heated to 450-640 DEG C now, pre-
After heat, it is easy to there is slivering, glass properties caused to be unevenly distributed, therefore, it is necessary to the pre-heating technique of tempered glass into one
Step research.
Invention content
The purpose of the present invention is for existing problem, provide a kind of hydrothermal pretreatment method of tempered glass.
The present invention is achieved by the following technical solutions：A kind of hydrothermal pretreatment method of tempered glass, by glass material
Cutting obtains glass material to material on demand, and ensures that glass material surface and edge without apparent scuffing and crackle, then compile material with yellow grass
Hanging is taken out after the completion infusion 3-4 minutes in the sealing container equipped with boiling water after bundling glass material, is removed yellow grass and is compiled material, uses
It is anhydrous that surface is dried to after 85-90 DEG C of hot water injection, then successively after heated stove heat, quenching up to tempered glass.
As further improvement of these options, the glass material is Na2O-CaO-Si2O systems glass, glass material
Thickness be 3-5mm.
As further improvement of these options, the yellow grass compiles material will carry out following process before use：It will acquisition
