Then send the above into the kiln for firing. When transported into the kiln, it will pass through a low negative pressure pre-tropical zone. Some small glass-ceramic frit particles that are placed on the top layer are easily sucked away due to their light weight. , resulting in the lack of a lot of glass-ceramic frit particles on the surface layer, the flatness of the adobe is not high after firing, and pinholes or dissolution holes appear, which greatly affects the quality and aesthetics of the glass-ceramic composite board. The yield rate is not high

preparation example Construction

[0029] Preparation of the bottom glaze: use kaolin, quartz, potassium feldspar, albite, calcite, talc, dolomite, zinc oxide, and zircon powder as raw materials for the bottom glaze, and add appropriate amount of water and 0.5% tripolymer Sodium phosphate, 0.3% methyl cellulose, ball milled into the chemical composition of SiO2: 50%, Al2O3: 20%, CaO: 9%, MgO: 2%, K2O: 2%, Na2O: 3%, ZnO: 4 %, ZrO2: 10%, and the fineness is 0.5% of the slurry bottom glaze on the 10,000-hole sieve for use.

[0030] It should be noted that the preparation of green body powder, micropowder formula components and bottom glaze given here can be replaced by other formula components in the common knowledge, and all can be applied to the composite glass-ceramics of the present invention. In the preparation method of the plate. The bottom glaze mainly serves as a covering function, so the make-up soil with high whiteness is usually selected, and its expansion and contraction coefficient during firing is ...

Abstract

The invention provides a green brick of a single fired glass ceramic composite board. The green brick comprises a green brick body layer, a ground coat layer and a glass ceramic frit layer from bottom to top, wherein a hydrophobic layer is also arranged between the green brick body layer and the ground coat layer; the glass ceramic frit layer is formed by applying a microcrystalline frit particle suspension prepared by mixing glass ceramic frit particles with a frit particle binder to the surface of the ground coat layer; the frit particle binder comprises the following components by mass fraction: 6.5-7.5% of nonionic polyurethane associative thickening agents, 3.2-4.4% of white carbon black, 1-1.5% of defoaming agent, 0.3-1.3% of dispersing agents and the balance of solvents. By using the green brick, the glass ceramic frit particles on the surface can not be drawn away by a draught fan in a preheating zone during firing, thus avoiding waste and reducing the defect rate of the glass ceramic composite board product.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a brick adobe made of a glass-ceramic composite plate fired once. Background technique [0002] Since the technology of glass-ceramic composite panel has been maturely applied, its technology has been continuously developed and innovated, and the product has become a high-grade decorative material in the market because of its transparent micro-crystalline frit particles and personalized decorative effect, and is well received by consumers. favorite. [0003] The adobe of the glass-ceramic composite board fired at one time includes a green body layer and a glass-ceramic frit layer from bottom to top, and the glass-ceramic frit layer is generally composed of glass-ceramic frit particles, specifically, ceramic powder The material is pressed to form an adobe, and then a layer of glass-ceramic frit particles is spread on the surface to form a glass-ceramic frit layer t...
