Abstract
The invention relates to a process method for toughening ultra-thin glass. The process method comprises the following steps of: (a) cutting: firstly cutting glass products according to required sizes, and intensively putting the cut glass products into a product basket; (b) preheating: putting the product basket into a preheating furnace, and slowly rising the temperature to 250-300 DEG C, wherein the temperature preservation time is 1-2 hours; (c) strengthening: putting the preheated products into potassium nitrate solution, and slowly rising the temperature to 400-450 DEG C, wherein the temperature preservation time is 6-9 hours; (d) cooling: transferring the strengthened products into a cooling chamber, and slowly cooling to the normal temperature; and (e) cleaning: cleaning the cooled glass products. After repeated experiments is carried out by utilizing the process method, according to technical parameters utilized in the process method, the glass is relative high in rigidity, is not easy to damage and is good in forming effect, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of processing method in the glass manufacturing area, especially relate to a kind of ultra-thin glass intensification technique method.
Background technology
Toughened glass claims chilled glass again.It is with method physics or chemistry, forms a compressive stress layer at glass surface, and itself has high compression strength glass, can not damage.Do the time spent when glass is subjected to external force, this shell of compression can be avoided the cracked of glass with the payment of part tensile stress, though toughened glass inside is in bigger tensile stress state, but the inside zero defect of glass exists, and can not make becoming to destroy, thereby reach the purpose that improves strength of glass.As everyone knows, the tiny crack of material surface is the major cause that causes material breaks, because tiny crack is expansion gradually under the effect of tension force, at last along crack initiation, and glass is behind tempering, because there is bigger stress in the surface, can make the tiny crack of glass surface become trickleer under squeezing action, even " healing ".And present manufacturing process, because all can there be defectives such as glass hard (HRC65 is not enough, molding effect is undesirable in the difference of every technical parameter that each producer adopts.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can make the ultra-thin glass intensification technique method that glass ware forming is effective and hardness is big.
The technical solution adopted for the present invention to solve the technical problems is: a kind of ultra-thin glass intensification technique method, and the step of described processing method is:
A, cutting at first cut into glassy product and are placed in the product basket in the needed set of dimensions;
B, preheating are placed into the product basket in the preheating oven, and temperature is slowly risen to 250-300 ℃, and soaking time is 1-2 hour;
C, reinforcement, the product that preheating is good is placed in the potassium nitrate solution, and temperature slowly rises to 400-450 ℃, and soaking time is 6-9 hour;
D, cooling move into and bring down a fever indoorly strengthening the product that finishes, and temperature slowly is reduced to normal temperature;
The glassy product after the cooling is cleaned in e, cleaning.
Further, in order to reach better pre-heat effect, preheating temperature rises to 300 ℃ among the described step b, and soaking time is 1.5 hours.
Further, in order to reach better strengthening effect, strengthening temperature among the described step c is 420 ℃, and soaking time is 8 hours.
Further concrete, the purity of described saltpetre liquation is more than 99.9%.
Further, in order to accelerate the reinforcement process of glass, add catalyzer in the described saltpetre liquation, add 30-40g in the potassium nitrate solution of every 100kg.
The invention has the beneficial effects as follows: adopted after the above-mentioned processing method, through repeatedly experiment, the technical parameter that the present invention adopts can make that the hardness of glass is bigger, is not easy to damage and effective in moulding, increases production efficiency.
Description of drawings
Fig. 1 is the schema of processing step of the present invention.
Embodiment
A kind of ultra-thin glass intensification technique method as shown in Figure 1, the step of described processing method is:
A, cutting at first cut into glassy product and are placed in the product basket in the needed set of dimensions;
B, preheating are placed into the product basket in the preheating oven, and temperature is slowly risen to 250-300 ℃, are preferably 300 ℃,, soaking time is 1-2 hour, is preferably 1.5 hours;
C, reinforcement, the product that preheating is good is placed into purity in the potassium nitrate solution more than 99.9%, and adds the catalyzer that contains the Li ion in potassium nitrate solution, adds 30-40g in the potassium nitrate solution of every 100kg; Temperature slowly rises to 400-450 ℃ afterwards, is preferably 420 ℃, and soaking time is 6-9 hour, is preferably 8 hours;
D, cooling move into and bring down a fever indoorly strengthening the product that finishes, and temperature slowly is reduced to normal temperature;
The glassy product after the cooling is cleaned in e, cleaning.
The making principle of toughened glass: chemically toughened glass is that the chemical constitution by the surface that changes glass improves glass intensity, generally is to use ion exchange method to carry out tempering.Its method is to contain the silicate glass of alkalimetal ion, be immersed in lithium (Li ion) salt of molten state, the Na ion of surface layer of glass or K ion and Li ion are exchanged, the surface forms the Li ion exchange layer, because the coefficient of expansion of Li ion is less than Na ion and K ion, outerly shrinks less and internal layer shrinks bigger thereby cause in process of cooling, after being cooled to normal temperature, glass just is in the internal layer tension equally, the state of outer pressurized, and its effect is similar to physical toughened glass.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
