Description
Technical Field
The invention relates to a preparation process of a colored glaze utensil, in particular to a process for preparing a colored glaze utensil by adopting a colored glaze utensil forming die.
Background
The colored glaze is prepared by firing various artificial crystals as raw materials at a high temperature of more than 1000 ℃, and has brilliant and brilliant color and bright quality. The material for manufacturing the colored glaze in ancient China is obtained from byproducts generated in the casting of bronze wares, and then the colored glaze is manufactured by refining and processing.
Colored glaze belongs to an art with a great value, and has two reasons: firstly, the ancient method colored glaze material is special, and its preparation technology is fairly complicated, comes in the fire, goes in the water, can only accomplish by dozens of processes, and some light preparation process takes ten to twenty days, and mainly relies on the manual work. The difficulty in grasping the fire is rather difficult, and it is more difficult to say that one half depends on skill and one half depends on luck. Only one furnace is taken out, and the yield is only 70 percent. More importantly, the ancient colored glaze is not recyclable, that is, once a little bit of problem occurs, dozens of procedures in ten days, and most people pay attention to the east stream immediately. Secondly, the coloured glaze is not only a material, more a cultural product, and more importantly, the coloured glaze product is unique, does not have two coloured glaze products that the mould is the same.
The preparation process (dewaxing process) of the existing colored glaze utensil is as follows:
1) creative design: expressing the originality through a planar design draft;
2) prototype manufacturing: sculpturing the three-dimensional model according to the drawings;
3) preparing a silica gel soft mold: uniformly coating silica gel on the surface of the three-dimensional model, and solidifying the silica gel into a silica gel soft model (taking out the three-dimensional model, and optionally fixing the three-dimensional model by gypsum);
4) casting a wax mold: preparing wax slurry, pouring hot-melt wax into the soft silica gel mold, and naturally cooling;
5) removing the wax mold: removing the cooled wax mold from the soft silica gel mold (or removing the soft silica gel mold from the wax mold);
6) trimming a wax mold: the wax mould is easy to shrink and deform by cooling, and the mould line trace left in mould removal needs to be finished perfectly by a tool carefully;
7) preparing a plaster mold: preparing the fire-resistant gypsum with the correct proportion, and pouring and embedding the modified wax mold to obtain a wax-containing gypsum mold;
8) steam dewaxing: the whole wax-containing plaster mould is put into a dewaxing machine and heated by steam, and the refractory plaster hard mould is obtained after dewaxing.
9) Selecting raw materials: in order to accurately control the proportion of various colors and the flowing aesthetic feeling, colored glaze raw materials with specific colors and sizes are selected according to the modeling and design, and the distribution positions of color blocks are arranged;
10) and (3) furnace entering and sintering: after the mould is cleaned and the dust is removed, the whole plaster hard mould and the prepared colored glaze material are put into a furnace to be heated slowly, so that the hot-melt softened colored glaze raw material flows into the plaster hard mould slowly like maltose for forming;
11) removing the gypsum: removing the gypsum mold, and taking out the cooled colored glaze rough blank;
12) f, cutting and repairing: cutting and repairing redundant colored glaze on the grouting opening part of the colored glaze rough blank;
13) coarse grinding and fine grinding: grinding and flattening the pouring opening of the colored glaze by coarse and fine grinding sand;
14) cold fine repair: the surface of the work is more uniform and fine by carefully carving with a diamond pen head and other tools;
15) and further performing fine processes such as sand blasting, grinding, polishing and the like according to requirements until the finished product of the colored glaze utensil is obtained.
The process steps are a theoretical preparation method of a single colored glaze utensil, and in the actual industrial batch production process, the three-dimensional model is required to be transformed into a resin hard film, and then the resin hard film is transformed into a batch silica gel soft mold. The reason is that the three-dimensional model is often a mud film (which is convenient for a carving master to sculpture and form) made of a softer material, so that the three-dimensional model can be deformed or damaged in the process of being transformed into a silica gel soft mold or in the process of being stored, and thus the three-dimensional model can not be transformed into a large number of silica gel soft molds through one three-dimensional model, and further the mass production can not be carried out.
Whether theoretical or industrial, the above process has a technical drawback, which makes it difficult or impossible to implement the process for preparing some special colored glaze tools. For example, the technical problems that a small-caliber colored glaze vase needs to be prepared are as follows:
the model of the vase is a hollow structure, so the model provided by the wax mold is also a hollow structure, and the silica gel soft mold in the hollow structure needs to be taken out from the cavity of the wax mold (namely, the process step 5), but the silica gel soft mold in the cavity is difficult to take out because the wax mold is a small-caliber model, and the wax mold is damaged even if the silica gel soft mold is taken out with a high probability, so that the subsequent processes cannot be carried out.
In the conventional process, in order to prepare the devices such as the small-caliber vase, the firing technology is basically realized, and the approximate process steps are as follows:
1) material melting: the required various pigments are put into a large furnace for smelting, and the molten colored glaze rotates on an iron rod.
2) Selecting materials: taking the colored glaze out of the colored glaze body from a traditional furnace with a temperature of 1400 ℃ and a length of 1.5 meters by using a blowing cylinder;
3) blowing: the colored glaze is continuously rotated and molded after being taken out of the furnace, the temperature of the colored glaze taken out of the furnace is high, the softness of the melted colored glaze is mastered, and the colored glaze is molded within a few seconds;
4) molding: in the molding process, master workers need to blow by using a blowing cylinder in hands to ensure the shape of the colored glaze, and the finished product rate is extremely low because the scale is difficult to hold;
5) annealing: after the colored glaze is formed, teachers and workers need to put the fired colored glaze into a heat preservation kiln, the temperature is preserved for 4 days at more than 500 ℃, and if the colored glaze bottle body is not cracked, the colored glaze is cooled and formed.
The process is easy to have obvious technical defects, such as extremely low yield, incapability of mass production and the like.
