(5) the ceramic tile body after burning till carries out cold working such as edging according to different needs, sorting, is packaged as finished product.
The ceramic tile with sealed porosity that the inventive method is produced can be done surface decoration with silk screen printing, dry method or wet method glazing at ceramic brick surface according to decorating needs equally.
The main chemical one-tenth scope of the basestocks that uses among the present invention is divided into: SiO
255%～67%, Al
2O
317～24%, Fe
2O
3+ TiO
2＜10%, CaO+MgO 3～8%, Na
2O+K
2O 5～10%.
The weight ratio of the shared ceramic basestocks of described foam material is 2-30%
Advantage with heat-insulation and heat-preservation function ceramics brick and preparation method thereof of the present invention is: owing to sneak into the organic or inorganic foam material in ceramic tile body basestocks, high temperature foaming by foam material, just in the ceramic tile body, form stable sealed porosity after the process of cooling, utilize the air heat transfer property to can not show a candle to the characteristic of ceramic tile itself, thereby can obtain effective heat insulation and preservation effect, this ceramic tile is easy for installation simultaneously, need not to fix, and its surface can be adopted the surface decoration of silk screen printing, dry method or wet method glazing equally with special support.
Through a large amount of evidences, in the course of processing, the experiment proved that the temperature of selection and variation thereof, process period for the very significant effects that is formed with of closed pores, in temperature and time scope of the present invention, the best that tells on of the size in its hole and quantity.
Brick of the present invention can be widely used in required requirements such as wall decoration and insulation, has application promise in clinical practice.
