Production of glazed polished tiles, how to stain?
Effects of polished glaze tile suction in the production process, causes and solutions
1 the firing process influencing factors of polished glaze tile suction
A. when the body burned or burning, and also for surface suction phenomenon, it needs according to the actual situation and the furnace temperature curve up or cooling process, if there is any burning, body size is too large, stomata increases, there will be plenty of body surface capillary suction, pollution also decreased. While reasonable control a certain percentage of positive pressure.
B. controlled oxidative phase of porosity, particularly 950~1050℃ of temperature zones extend as far as possible the exhaust timing, which can promote the body to the kiln closed porosity, lower body, and helps to improve the anti-fouling properties.
2 effect of polished glaze tile suction in the production process, causes and solutions
A. Adobe goes up too much, in the process of polishing surface grinding much easier to suction.
B. da under body too large, insufficient in the polishing process grinding easier to suction.
C. body cloth to the surface concave inconsistency does not match the local grinding easier to suction.
Solution: according to the body's deformation and adjusted for body surface smoothness of brick or cloth, to meet the process requirements.
