Abstract
The invention discloses a catalyst for chemical enhancement of an ultrathin optical glass panel, and applications of the catalyst. The catalyst is prepared by mixing the following raw materials in percentage by weight: 25-50% of potassium carbonate, 5-25% of potassium chloride, 2-15% of sodium chloride, 3-25% aluminium oxide, and 2-15% of diatomaceous earth. The applications of the catalyst comprise the steps of production and enhancement of fused salt. The catalyst can accelerate the ion exchange between Na<+> in glass and K<+> in fused salt, so as to offset microcracks, and can obviously shorten the time for chemical enhancement on the basis of not reducing the properties of the ultrathin optical glass panel.
Description
Technical field
The present invention relates to chemical catalyst composition and application thereof, relate in particular to a kind of for chemical enhanced its application of catalyst of ultra thin optical face glass.
Background technology
There is a small amount of micro-crack in the surface of ultra thin optical face glass, causes that easily stress is concentrated and cause glass to break easily, has had a strong impact on the tensile strength of ultra thin optical face glass.Commonly used is with a period of time in the fused salts such as its immersion potassium nitrate, to increase mechanical strength and the heat endurance of glass at present.
Its principle is: the ultra thin optical face glass is immersed in the fused salt of potassium nitrate, time was from tens hours to tens hours, Na+ in the glass and the K+ ion in the fused salt, ion-exchange occurs, because the radius ratio Na+ ion of K+ ion is large, K+ replaces the Na+ ion in the glass, is expanded in surface " jammed ", produce stress, the ultra thin optical face glass is strengthened.
The chemical enhanced arts demand time of existing ultra thin optical face glass is longer.Thereby a kind of method that can significantly shorten the catalyst of chemical enhanced process time of ultra thin optical face glass and utilize this catalyst need to be provided, to shorten the reinforcement process time, raise the efficiency.
Summary of the invention
The problems referred to above that exist for solving prior art the object of the present invention is to provide a kind of catalyst that can significantly shorten the chemical enhanced process time of ultra thin optical face glass.
Another object of the present invention provides the application of above-mentioned ultra thin optical face glass forced fluid in chemically enhancing glass.
For achieving the above object, the present inventor has designed a kind of catalyst that can significantly shorten the chemical enhanced process time of ultra thin optical face glass through a large amount of research and performing creative labours.The catalyst of the chemical enhanced usefulness of this ultra thin optical face glass is characterized in that raw material mixes as following weight percent: potash 25 ~ 50%, potassium chloride 5 ~ 25 %, sodium chloride 2 ~ 15%, alundum (Al2O3) 3 ~ 25%, diatomite 2-15%.
Described catalyst mixes by following materials in percentage by mass: potash 40%, potassium chloride 20 %, sodium chloride 5%, alundum (Al2O3) 20%, diatomite 15%.
The application of this catalyst in the ultra thin optical face glass is strengthened is characterized in that comprising the steps:
(1) manufacturing of fused salt:
A, preparation, the molten salt furnace wiped clean, furnace temperature is raised to 150 ℃, constant temperature 30 minutes;
After B, the molten salt furnace oven dry, begin to add potassium nitrate, after melting fully, constant temperature precipitates more than 12 hours;
After C, constant temperature finished, the weight ratio of pressing potassium nitrate added catalyst, makes the reinforcement fused salt;
(2) strengthen step:
It is preheating in 330～350 ℃ the insulating box that step a. will ultra thin optical face glass be strengthened places temperature, time 2 h;
It is 400 ℃-420 ℃ reinforcement fused salt that step b. places temperature with the ultra thin optical face glass of step a gained, 6 hours time;
Step c places the ultra thin optical face glass of step b gained in the annealing furnace, and cooling when temperature is reduced to 75 ℃-85 ℃, is come out of the stove naturally;
Steps d. place 50 ℃ of pure water to clean the ultra thin optical face glass of step c gained.
The effect that should be used for the chemical enhanced catalyst of ultra thin optical face glass is: accelerate Na+ and the interionic ion-exchange of the K+ in the fused salt of glass, remedy micro-crack.Can on the basis that does not reduce ultra thin optical face glass properties, significantly shorten its chemical enhanced time.
Do not add that catalyst is normal to be strengthened and the reinforcement performance comparison table that uses the catalyst reinforcement (with U.S. CORNING material 2318 as example).See accompanying drawing 1.
By using and the comparison of not using catalyst, not only enhanced time has reduced 40%, and the discreteness of its falling sphere obviously reduces, and the CS performance improves more than 15%, and the DOL performance slightly is improved, and 4 buckling performances slightly descend, but all meet the demands far away.
