Problems solved by technology

Also because of the low yield rate and too complicated process, it has not been popularized, and the form of expression is also single.
[0003] The twisted tire is spliced ​​with different ratios of soil. The specific ratio adopts the ratio of the existing technology or adds different colorants according to personal color preferences. The difference in color and pattern is closely related to the production method and production process. The molecular arrangement is changed during the production process, and the inevitable output deformation and distortion when kneading the twisted tire pattern by hand, so that most twisted tire parquet works are limited to daily-use utensils and small-area creations; cracking during the kneading process is usually Caused by uneven drying and wetness of the clay board, uneven thickness
If the thickness is too thin, it will easily lead to warping
The texture and carcass are also prone to warping, deformation, cracking, and pattern distortion, resulting in low yield. Porcelain fired at high temperature cannot be recycled and is not environmentally friendly.
The traditional hand-kneaded twisted tires cannot control the pattern lines very well, so the waste mud needs to be cut off continuously, resulting in redundant scraps, which increases the cost of raw materials, is time-consuming and labor-intensive, and is not environmentally friendly.

Embodiment 1

[0025] A method for preparing a strand ceramic, comprising the following steps,

[0026] Step 1: After fully mixing the mud and sieved coloring agent with water and white vinegar, knead it into the mud one by one, knead the mud until it is even and dense, cut it into small pieces and put it in a container with a moderate water content. The pure milk is kept in a sealed bag for two weeks in a dark and humid environment. After the mud is aged, it is made into porcelain mud with high chroma, high transparency and strong plasticity, and then added with metal oxides for coloring to make a high-quality twist tire colored porcelain clay;

[0027] Step 2: Add corresponding white porcelain clay to the porcelain clay according to the processing requirements, and adjust different color levels in turn to express the gradient effect and enrich the color expression;

[0028] Step 3, arrange the color clay in order according to the color scale, and make a color clay block with a gradient ef...

Embodiment 2

[0043] Using the manufacturing steps in Example 1 to make an octagonal small bowl, the fractal patterns of 8 parts of the twisted mud board, with the rice character as the axis, correspond to the octagonal female plaster mold, and the fractal on the mud board corresponds to the upper mold Then squeeze inward to push the clay plate into the mold. At the same time, the pattern of the clay plate and the shape of the mold are symmetrical, so that the clay plate fits the mold to avoid air and impurities. Only when the clay plate is tight can the deformation and cracking be reduced, and then add The upper base is squeezed together to complete the octagonal small bowl.

Embodiment 3

[0045] Adopt the production steps in Example 1 to make vases. The vases are molded by mud boards and billets, and the rectangular mud boards are obtained to make straight cylinders. Put the drawing machine on the front and push and expand from the inside of the straight cylinder after turning on the billet drawing machine. , to make an ideal vase shape, (in the process of pushing and expanding, the pattern of the twisted tire will change with the clockwise or counterclockwise inclination of the drawing machine. If you want the pattern to remain vertical, turn the rotation of the drawing machine Adjust the direction to the opposite direction, repeat the push and expand steps, and return the pattern to the vertical state. This kind of bidirectional drawing technique in the positive direction is also used when drawing blanks to make twisted tire utensils.) After drying in the shade, trim and polish.

Abstract

The invention relates to a preparation method of twisted-earth ceramic, and belongs to the technical field of twisted-earth ceramic. The porcelain clay is aged by milk, and a coloring agent is added,so that plasticity is improved, and a cracking phenomenon caused by poor plasticity is reduced; a double-sided multi-directional hand rolled sheet shaped like a Chinese character "mi" is adopted, andthickness and uniformity, and trend of grains are controlled, so that the grains and the body cannot be warped and deformed; a mud strip mechanism is used to manufacture geometric continuous patterns,the length of mud strips can reach several meters, and the mud strips can be used to manufacture large-area twisted-earth ceramic or inserted ceramic; geometric patterns are different in change and uniform in rule; waste of corner mud materials is effectively avoided, and zero loss can be almost realized; a printing blank or mud plate forming method is adopted, so that blank repairing is not needed, and waste is avoided. Therefore, raw material cost is reduced, resources are saved, the environment is protected, and meanwhile, a great of resources and manpower are saved. Meanwhile the rate offinished products is improved to the maximum extent, the efficiency is higher than efficiency of manual production of twisted earth, the completion degree of images is higher than the completion degree of hand painting, and low-cost manufacturing or batch production is realized.

Description

technical field [0001] The invention relates to a preparation method of twisted tire ceramics, in particular to a preparation method of twisted tire ceramics, which belongs to the technical field of twisted tire ceramics. Background technique [0002] Tilting is a ceramic technique that has existed since the Tang Dynasty in China. Due to the low yield and complicated production process, it has gradually been ignored. In recent years, potters including Japan and many Western countries have begun to use the twisted tire technique for creation and production. Also because of the low yield rate and too complicated process, it has not been popularized, and the form of expression is also single. [0003] The twisted tire is spliced ​​with different proportions of soil. The specific proportion adopts the proportion of the existing technology or adds different colorants according to personal color preferences. The difference in color and pattern is closely related to the production...
