Technical Field

The invention relates to the technical field of nixing pottery preparation, in particular to a method for preventing mildew stains from growing after the nixing pottery is polished for a long time.

Background

Nixing pottery, specialty product of the Kyowa city of the Guangxi Zhuang autonomous region, China geographical marker product. The traditional nixing pottery takes purple red pottery clay which is unique to both banks of east and west of the Qinjiao, Guangxi, as a raw material, the east clay is sealed and stored, the west clay is taken back and is crushed, dissolved and oxidized by sunshine and rain for more than four to six months to reach a weathered state, and then the west clay is crushed and mixed according to the proportion of 4:6 to prepare a pottery blank. The east mud is soft and is meat, the west mud is hard and is bone, the bone and the meat are mutually supported and fired by the firing technology of the nixing pottery to form the nixing pottery.

The unique Qinzhou nixing pottery does not need to be added with any ceramic pigment, the kiln change generated in the firing process is a great artistic feature of the unglazed nixing pottery, when the kiln is raised to the critical point of 1120 ℃, the phenomenon of channeling of a few parts of carcasses is occasionally discovered, various colorful colors and textures are naturally formed, and the true appearance of the nixing pottery is discovered after surface oxides are polished. The Qinzhou nixing pottery has the unique color and texture and has various colors such as natural bronze, tiger spot, big class, dark green and the like. In order to prevent damp and mildew, in the prior art, a polished nixing pottery product is heated, food paraffin is coated on the outer surface of the nixing pottery product, and then the nixing pottery product is polished by a polishing cloth wheel, so that the nixing pottery product achieves the effects of brightness and elegance, and is a delicate decorative handicraft in places such as homes, offices, scenic spots and the like. However, in the treatment process, after the paraffin is contacted with air for a long time, most of nixing ceramics still have mildew, the color becomes yellow and dark, the nixing ceramics cannot be directly wiped clean by a towel, the aesthetic feeling of the nixing ceramics handicraft is greatly affected, and the nixing ceramics are polished again to remove the mildew, so that manpower and material resources are wasted.

Therefore, it is necessary to develop a method for preventing the growth of mildew after the polished nixing pottery is placed for a long time.

Disclosure of Invention

The invention aims to solve the technical problem of providing a method for preventing mildew stains from growing after nixing ceramics are polished for a long time.

In order to achieve the purpose, the invention adopts the following technical scheme:

a method for preventing mildew spots of polished nixing ceramics after long-time placement is characterized in that a film forming material is attached to the surface of the polished nixing ceramics.

In order to obtain a better adhesion effect, the invention adheres the film-forming material to the polished surface of the nixing pottery by a smearing and/or polishing method.

In order to obtain better adhesion effect, the film-forming material is attached to the polished surface of the nixing pottery by a coating and polishing method.

In order to obtain better adhesion effect and mildew-proof effect, in the method, polished nixing ceramics and film-forming substances are put into a kiln, the temperature is raised until the film-forming substance materials are molten, the nixing ceramics and the film-forming substance materials are taken out, the film-forming substance materials are coated on the surface of the polished nixing ceramics, when the temperature is reduced to 75-85 ℃, redundant film-forming substance materials on the surface are scraped, and when the temperature is reduced to 35-45 ℃, polishing is carried out.

In order to obtain better mildew-proof effect, when the temperature is reduced to 35-45 ℃, three times of polishing are carried out, specifically: polishing once by a polishing machine, polishing for the second time by a thin cloth wheel, and polishing for the third time by a clean thin cloth wheel.

In order to obtain better adhesion effect and mildew-proof effect, in the method, before the coating is adhered to the surface of the polished nixing pottery, the film-forming material is continuously heated for 60-120min at the temperature of 180-220 ℃, and then cooled. Through the processing, the moisture in the film forming material can be removed, and after the film forming material is attached to the surface of the polished nixing pottery, the nixing pottery can be effectively prevented from being mildewed after being contacted with humid air for a long time, and the phenomenon that the nixing pottery becomes yellow and dark after being placed for a long time can be effectively prevented.

In order to prevent mildew stains after the polished nixing pottery is placed for a long time, the material of the film forming substance is a mixture of semi-refined paraffin and plastic particles. In order to make the nixing pottery more environment-friendly and safer, the plastic particles used in the invention are food-grade.

In order to obtain better anti-mildew effect, the weight ratio of the semi-refined paraffin wax to the plastic particles in the film forming substance material is 100: 1-5.

More preferably, the weight ratio of the semi-refined paraffin wax to the plastic particles in the material of the filmable substance of the present invention is 100: 3.

More preferably, the plastic particles according to the invention are PE (polyethylene) or PP (polypropylene), both selected from PE and PP being food grade, and food grade plastic particles are selected, which generally do not release harmful substances upon storage.

The polished nixing pottery is the nixing pottery polished after firing.

In the method, the preparation method of the polished nixing pottery comprises the following steps:

the east mud is sealed and stored, the west mud is taken back and is broken up, dissolved and oxidized through six months of sunshine and rain to reach a weathering state, then the east mud and the west mud are crushed, mixed according to the weight ratio of 4:6, made into pottery blanks, formed to be made into nixing pottery blank body samples, heated to 1150 ℃, insulated for 3h, fired, formed and polished to obtain polished nixing pottery samples.

Compared with the prior art, the invention has the beneficial effects that:

according to the method, before the film forming material is attached, the moisture in the film forming material is removed by heating, the nixing pottery and the film forming material are heated before the attachment, and the film forming material is attached to the surface of the polished nixing pottery by adopting the combination of smearing and polishing.
