Abstract
The present invention relates to a microwave sintering process of packed cadmium selenium red glaze, a glaze material mixed with cadmium sulfoselenide and packed with coloring materials is put in an industrial microwave sintering furnace to be sintered under the conditions of normal pressure, oxidative atmosphere, frequency of 300MHz to 300GHz, and temperature at 600 to 1600DEG. C, after the heat is held, the glaze material is taken out of the furnace and is cooled. The cadmium sulfoselenide of a colouring pigment of the glaze is quickly sintered and attached in the glaze to obtain the high-quality glaze surface. The blank glaze is heated uniformly, and the color of the glaze surface is smooth and uniform. The present invention has the advantages of fast glaze reaction, low sintering temperature, stable glaze color, high sintered yield, simple technology, short producing cycle and high production efficiency and economic efficiency.
Description
Technical field
The present invention relates to a kind of preparation method of ceramic glaze, specifically, relate to a kind of sintering method of packed cadmium selenium red glaze.
Background technology
Cadmium sulfoselenide occlusion pigment [Cd (Se
xS
1-x)-ZrSiO
4] have cadmium sulfoselenide [Cd (Se concurrently
xS
1-x)] the peculiar vividness of colorant and certain stability, on decorating ceramic products, obtained using widely.But after adding occlusion pigment formation packed cadmium selenium red glaze material in the parent glaze, the glaze that is in molten state under the hot conditions can dissolve and be wrapped in cadmium sulfoselenide [Cd (Se
xS
1-x)] the outer zirconium silicate (ZrSiO of mixed crystal
4) protective layer, reduce encapsulation ratio, influence colour stability.Therefore, when sintering packed cadmium selenium red glaze material, if can improve the speed of response of glaze, reduce the sintering temperature of glaze, that will form very favourable to overglaze.Existing resistance sintering mode is difficult to accomplish this point.
Summary of the invention
The technical problem to be solved in the present invention is; deficiency at existing traditional heating technology existence; a kind of method that can improve glaze quality is provided; it is a kind of microwave sintering method of packed cadmium selenium red glaze; utilize this method; can reach protection occlusion pigment colour generation, improve the purpose of sintering qualification rate.
Technical solution of the present invention is that the microwave sintering method of described packed cadmium selenium red glaze is: adopt to be mixed with cadmium sulfoselenide occlusion pigment [Cd (Se
xS
1-x)-ZrSiO
4] glaze insert in industrial microwave sintering oven/kiln and utilize micro-wave energy to carry out sintering in the normal pressure and oxidizing atmosphere, microwave frequency is 300MHz～300GHz, preferred value is 2.45GHz or 915MHz.The microwave sintering temperature is 600～1600 ℃, time 0～10hr, and the insulation postcooling is come out of the stove.
Principle of work of the present invention is: the present invention is a kind of novel method with the microwave sintering packed cadmium selenium red glaze, this method utilizes that the microwave sintering temperature rise rate is fast, physical-chemical reaction characteristic rapidly, the color development pigment cadmium sulfoselenide of glaze burnt apace be attached in the glaze, better glaze quality can be obtained, and sintering qualification rate can be improved.Specifically, in the microwave sintering process, interior of articles atom or molecule are directly and microwave produces coupling and absorption micro-wave energy self heats, and realize being rapidly heated and sintering; In addition, because the characteristic of microwave heating can produce a kind of " non-thermal effect ", reduce activation energy and reduce sintering temperature.But fast cooling behind the microwave sintering, no thermal source pollutes.The product of microwave sintering, performance obviously are better than normal sintering.These characteristic conforms of microwave sintering technology packed cadmium selenium red glaze agglomerating arts demand.So the present invention changes the packed cadmium selenium red glaze product with ordinary method processing into and puts into the whole processing of industrial microwave sintering oven, sintering in normal pressure and oxidizing atmosphere heats up fast evenly, reaches sintering temperature very soon.I.e. cooling is come out of the stove after the insulation.Reduce 5-300 ℃ than normal sintering temperature.
The invention has the beneficial effects as follows that from inside, the base glaze heats up evenly, the smooth homogeneous of glaze color and luster as the heat of above-mentioned microwave sintering; Utilize it " non-thermal effect " of microwave to increase the speed of response of glaze, reduce activation energy so that reduce the glaze sintering temperature, can improve occlusion pigment and be colour-stable; And the sintered body internal stress is little, has both made Fast Sintering also can not cause blank cracking, thereby the blank sintering qualification rate is improved greatly.Technology of the present invention is simple, and is with short production cycle, and it is colour-stable that glaze is, and the sintering qualification rate height has improved production efficiency and economic benefit.
