Description
Technical field
The present invention relates to glass technology field, a kind of enhanced water resistance glassware and preparation method thereof is specifically disclosed.
Background technique
Soda-lime glass daily utensil is the most common packaging material and container in life.But soda-lime glass structure for
It is not close for molecule and ion to enter, the effect with water especially in environment.By long-time use and use or
The variation of environment temperature, water can invade glass by diffusion, form analysis alkali phenomenon so that glass be etched and lead to performance
It reduces.The main reason is that: water is reacted with silicon oxygen skeleton, is generated Si-OH key, is broken network；Due to glass in dealkalize surface
Water resistance it is 10 times lower than dealkalize surface, alkali metal ion in glass is with Na+ by diffusion and the H+ ion exchange in water
Example, Na+ (glass)+H+OH- → H+ (glass)+NaOH, reactant NaOH accelerate the destruction of silica network.Therefore, enhancing and
Original glass, the i.e. water resistance of glass body in dealkalize surface are improved, becomes and improves the important of soda-lime glass vessel water resistance
Approach.
The most important mode of water resistance for usually improving soda-lime glass is to adjust the chemical composition of soda-lime glass.Such as appropriateness
It improves silicon oxygen amount, reduce alkali metal oxide content；Increase CaO in right amount using " depressor effect " of bivalent metal oxide；Draw
Enter the oxide such as ZrO containing high accumulation ion2；Strengthens network structure introduces appropriate B2O3；Appropriate introduce plays net mending work to network
Al2O3；" mixed alkali effect " mutually restrained using the diffusion of basic ion is using double alkali or polybase.Changed by these
The adjustment studied point, glass network consistency improve, and the diffusion coefficient of alkali metal ion becomes smaller, and ion exchange is hindered, glass
Glass particle water resistance improves.But glass body water resistance (HGB value) and corresponding clarifying temp, crystallization temperature, drop temperature
The numerical value such as degree, need to be calculated repeatedly using correlation formula or corresponding software to meet life according to chemical composition adjusted
It produces and requires.This method for improving glass water resistance by changing material side's composition, process is cumbersome, time-consuming and laborious, needs repeatedly
Adjustment.
