The invention discloses a ceramic glaze drying device, and relates to the technical field of ceramics. A supporting frame is included and rotationally provided with a drying barrel. A heater is fixedto the bottom of the drying barrel in an embedded manner. A driving shaft and a limiting casing pipe which are in pin joint to the supporting frame are fixed to the two sides of the drying barrel withthe same axis correspondingly. The driving shaft is in transmission connection with an intermittent mechanism driven by a motor I. A rotation shaft is in transmission connection with a dispersing mechanism, and the top of the drying barrel is detachably provided with a cover plate. Through swinging of the arranged drying barrel, swinging of inner ceramic glaze is promoted, and the effect of sufficient heating of the ceramic glaze through the heater is promoted. The arranged dispersing mechanism can rotate and can also transversely reciprocate, the ceramic glaze can be dispersed, stacking andcaking are avoided, and water vapor volatilization can be effectively improved; and an arranged axial-flow fan vertically upwards guides air, water vapor can be rapidly discharged out of the drying barrel, and the effect of rapid drying of the ceramic glaze is achieved.

The invention relates to the technical field of production of porcelains and particularly relates to an environment-friendly antique imitation porcelain with firewood-calcined porcelain imitation texture and a production method thereof. According to the environment-friendly antique imitation porcelain with firewood-calcined porcelain imitation texture and the production method thereof, low-cost raw materials are taken as the raw materials of a blank and a glaze material of the environment-friendly antique imitation porcelain with the firewood-calcined porcelain imitation texture, the raw materials are proportioned and a calcining process is controlled to obtain the environment-friendly antique imitation porcelain, the calcined environment-friendly antique imitation porcelain has the texture like a firewood-calcined porcelain, the surface of the calcined environment-friendly antique imitation porcelain has uneven metallic luster, and through control of the firing temperature and change of the firing atmosphere, the texture change on the surface of each porcelain is unique. The raw materials of the environment-friendly antique imitation porcelain are simple; compared with the firewood-calcined porcelain, the environment-friendly antique imitation porcelain has the characteristics of short calcining time, no combustion of firewood and high environmental friendliness; the environment-friendly antique imitation porcelain is of great significance on reduction of environmental pollution, development of cyclic economy and construction of resource-saving and environment-friendly society.

The invention provides a large-size ceramic decorative sheet and a formula process.The large-size ceramic decorative sheet comprises a blank layer and a glaze layer.The blank layer comprises a front side and an adhesive side, the front side is a plane, and the adhesive side is a concave-convex side with grooves.The specification of the blank layer is at least 900 mm*1800 mm, and the thickness of the blank layer is 5.5 mm.The glaze layer comprises a glaze bottom layer, a pattern layer and a glaze surface layer, the front side of the blank layer is evenly covered with the glaze bottom layer, the pattern layer is printed on the upper side of the glaze bottom layer, the pattern layer and the glaze bottom layer are covered with the glaze surface layer, and the thickness of the glaze layer is at least 0.3 mm.Formulas include a blank layer formula, a glaze bottom layer formula and a glaze surface layer formula.Pressure of dry pressing in the technological process is 240 MPa, drying temperature is 120-286 DEG C, the drying period is 62 min, upper temperate of firing temperature is 1196 DEG C, lower temperature of firing temperature is 1193 DEG C, and the sintering period is 73 min.

The invention discloses a high-strength color-sprayed crystalline ceramic glaze and a preparation method thereof. The high-strength ceramic glaze is prepared from the following raw materials in partsby mass: 38-58 parts of feldspar, 12-16 parts of quartz, 10-16 parts of calcite, 5-8 parts of barium carbonate, 7-10 parts of talc, 10-15 parts of silver oxide, 3-6 parts of kaolin, 8-10 parts of titanium oxide, 14-18 parts of zinc oxide, 6-8 parts of aluminum oxide, 1-4 parts of sodium dodecyl benzene sulfonate, 2-5 parts of lanthanum boride, 0.1-1.2 parts of niobium diselenide, and conductive antibacterial powder. The crystalline ceramic glaze has the beneficial effects that the strength performance and the anti-falling capability of a ceramic product can be improved, the practicability of the ceramic product is improved, the glaze smoothness is good, the glaze slip performance is good, the firing range is wide, the product appearance is regular, cleaning is easy, higher aesthetic feeling is generated, consumers have larger use visual senses, and the ceramic product is favored and praised by customers.

The invention discloses a ceramic bottom deglazing transmission device, which relates to the field of transmission belt equipment. In the prior art, if one transmission belt fails, the other will wear off the ceramic bottom, resulting in a decline in the qualified rate of ceramics, and the existing transmission belt is longer. The speed is slow, and the glaze on the conveyor belt is easy to dry and difficult to clean. By setting two turning rollers and a cleaning rod on the conveyor belt, the conveyor belt is bent into a "V" shape, and then sprayed and washed by the cleaning rod. The glaze on the conveyor belt is automatically cleaned to avoid the problem that it is difficult to clean up after long-term evaporation. Two rotary encoders are added to the two conveyor belts of the original deglazing unit, and the conveyor belt is realized by cooperating with the control unit. The role of monitoring, thus effectively avoiding the phenomenon of unqualified products caused by conveyor belt failure. The invention can be put into use only by improving the original device, reduces the production cost, improves the production efficiency of ceramics, and has broad market prospects.

The invention discloses a novel anti-electrostatic ceramic glaze as well as a preparation method and the application thereof. The preparation method comprises the following steps: carrying out continuous microwave synthesis on a common ceramic transparent glaze which mainly consists of ore materials at a temperature of 1100-1300 DEG C which is kept for 20-30 minutes, melting, directly pouring intowater for cold quenching, grinding prepared melt blocks in a ball milling tank, screening till 400 meshes so as to obtain a melt block powder, further mixing with a screened aluminum-doped zinc oxideconductive powder with150-200 meshes in a mass ratio of 20-30%, carrying out uniform ball milling mixing with 60% deionized water, at the same time adding sodium carboxymethylcellulose to regulate properties of a glaze material, so as to obtain glaze slurry, wherein the prepared glaze slurry is aged and applied to a dry ceramic blank by using a glazing method, and the glaze soaking time is 3 seconds. The ceramic blank after glaze application is dried in a drying tank, and is sintered by using a microwave continuous sintering process. The obtained ceramic glaze has the advantages of being smooth and flat in glaze surface, free of bubbles, transparent, good in chemical stability, non-toxic and environmental-friendly, low in price, and the like.
