Description

Technical Field

[0001] The invention relates to the technical field of copper handicraft production, in particular to a copper-clad porcelain process fired on the inner wall of a copper handicraft. Background Art

[0002] Copper-clad porcelain is a special process that combines copper with ceramic materials. This process not only retains the durability and beauty of ceramics, but also enhances the decorative effect and practicality of the product through copper wrapping. Copper-clad porcelain products are usually used to make wine sets, tea sets, vases, ornaments, etc., which have both ornamental value and certain practical value.

[0003] Existing copper-clad porcelain products are all made by coating the finished ceramic products with copper. There is no product design, the production process is rough, the process is unscientific, the outer copper material and the ceramic endometrium cannot be stably combined, and the resulting copper-clad porcelain products are of low quality and low craftsmanship appreciation.

[0004] Therefore, it is necessary to design a copper-clad porcelain process for firing the inner wall of copper handicrafts in response to the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a copper-clad porcelain process fired on the inner wall of a copper handicraft, so as to solve the problem proposed in the above background technology that the existing copper-clad porcelain products are all copper-clad on the outside of the finished ceramic products without product design, the production process is rough, the process is unscientific, the outer copper material and the ceramic inner embryo cannot be stably combined, the obtained copper-clad porcelain products are of low quality and the process appreciation is also low.

[0006] To achieve the above object, the present invention provides the following technical solution: a copper-clad porcelain process fired on the inner wall of a copper handicraft, the copper-clad porcelain process fired on the inner wall of a copper handicraft comprising the following steps:

[0007] Step 1: Ceramic Endomorph Preparation

[0008] 1) Design

[0009] Draw detailed drawings according to the product design requirements, such as using plane drawing tools to draw multi-view structural drawings, or using 3D modeling software to draw 3D models;

[0010] 2) Raw material selection and preparation

[0011] Select clay, quartz, feldspar, additives and kaolin of appropriate quality and mix them in appropriate proportions;

[0012] 3) Endomorph forming

[0013] Use molds or manual forming techniques, such as throwing and shaping, to make ceramic raw materials into the desired embryo shape;

[0014] 4) Endoem drying

[0015] Place the formed endoderm in a ventilated and dry place and allow it to dry naturally to a certain degree for subsequent processing;

[0016] 5) Biscuit

[0017] The dried endomorph is placed in a kiln for bisque firing to remove moisture and some organic matter in the endomorph and make the endomorph stronger;

[0018] 6) Glazing

[0019] The inner surface of the bisque-fired endomorph is glazed, and the outer surface can be glazed according to the design requirements of the product. For example, if the outer copper has a hollow design, the outer surface can be glazed to increase the beauty and protection of the product. The glaze is selected according to the design requirements.

[0020] Step 2: Outsourcing copper material preparation and processing

[0021] 1) Material selection

[0022] According to product needs and design requirements, choose appropriate copper materials, such as copper, brass, etc.;

[0023] 2) Cutting and plasticity

[0024] Use cutting machines, punching machines and other equipment to cut the copper material into the required shape and perform preliminary shaping. If the hollowing process is used, the hollowing process is performed on the preliminary formed outer copper material.

[0025] Step 3: Copper-clad porcelain bonding

[0026] 1) Coating

[0027] The processed copper material is tightly wrapped around the outside of the ceramic embryo by casting, welding, inlaying or mechanical fixing, and the copper material is hammered with a hammer with a rubber or wooden hammer head to ensure the fit between the copper material and the embryo;

[0028] 2) Trim

[0029] The copper-clad porcelain joint is trimmed to remove excess copper and uneven parts to make the product look neater and more beautiful.

[0030] Step 4: Surface treatment

[0031] 1) Polishing

[0032] Use grinding wheels, sandpaper and other tools to grind the surface of copper-clad porcelain products to remove burrs and rough parts on the surface;

[0033] 2) Polishing

[0034] Polish the polished products to make the copper surface smoother and brighter;

[0035] 3) Coloring and protection

[0036] According to needs, the copper surface can be colored to increase the color richness of the product. At the same time, a layer of protective paint or varnish can be applied to enhance the overall corrosion resistance and wear resistance of the copper-clad porcelain product.

[0037] Preferably, in step 1, the ventilation drying time of the endoderm is not less than 12 hours, the temperature range is 29-34° C., the humidity of the environment gradually decreases from 95% to 35% per hour, and the moisture content of the endoderm is finally controlled at 5%-20%.

[0038] Preferably, the polishing method in step 4 may be mechanical polishing or chemical polishing.

[0039] Compared with the prior art, the beneficial effects of the present invention are: the copper-clad porcelain process fired on the inner wall of the copper handicraft is simpler than the traditional method of coating the copper material on the outside of the ceramic finished product. Not only does it carry out a systematic product design in advance, organically combining the texture of the copper material and the characteristics of the ceramic, but it also optimizes the production process and production flow, greatly improving the quality of the copper-clad porcelain products and the process appreciation.
