The all standing mode that glaze is sprayed or drenched using leaching glaze equipment using glaze spraying cabinet, so that dry granular charity is burnt into after glaze；(2)
First using the bond properties of glue, then used using glaze spraying or printing equipment in all standing mode of green body or glaze glue spraying water
Various dry granular equipment, and with dry method mode by dry granular charity on glaze after be burnt into；(3) only with printing equipment in base face
Or the partial mulching mode of glaze part printing glue, using being burnt into after glue bond properties, then charity dry granular.
Currently, the most common process flow of dry granular decoration is: Ceramic Tiles green compact semi-finished product → glaze decoration → Spanish furnish
→ multiple groups spray head partial mulching mode sprays glue → charity dry granular or powdered rubber.This mode is thicker because wanting the dry granular of charity
It is more, therefore the glue quantity sprayed can increase significantly, and other purchase of equipment is on the one hand needed to meet the dosage for increasing glue in this way
Or number；On the other hand, glue dosage increases, and the water content in green body rises, and can reduce the intensity of green compact, cause transportational process
In it is damaged increase, while also to it is subsequent enter kiln moisture control bring pressure, cause fried base when firing the problems such as and bring hidden
Suffer from；And the mode of partial mulching glue also will cause local heating's unevenness, answer since base face water content and surrounding are different
The unbalanced hidden danger to cause idiosome to crack of power.
In addition, the technique of charity dry granular ornamental porcelain brick, principle are using the viscous of glue again after the above-mentioned water using sizing
Property bonds other materials, dry granular substance is fixed on product surface to reach, to play the role of that decorative pattern can be stablized.
But in the actual production process, the adhesive property of glue will receive the influence of various factors, to cannot fix well and steady
Fixed material grains required for fixed.Such as green body temperature, body drying degree, environment temperature, the factors such as Production Line Configured
