Glassware is usually washed and immersed in baskets and other fixing tools. The liquid just passes through frosting. The liquid temperature shall be between 250 ° C and 300 ° C.
There is also a blowing method, in which the glass product is placed on a tray or a fixed hanger, and the acid liquid is blown by a nozzle under a constant pressure to roughen the surface of the glass product. The composition and test of the acidic solution are the same as the impregnation method. After spraying the acid solution, wash with circulating water at 40-70 ° C. The temperature of the spray solution is 400 ° C to 500 ° C.
- Process system and factors affecting frost formation
