First, the technical steps of ceramic repair
1. Take photos of the original. Next is the cleaning work. Put the utensils into an ultrasonic cleaning machine, and add a proper amount of chemical reagent acetone to the clean water for micro-heating treatment to remove dirt and adhesive. After turning on the machine for 2 to 3 hours, the stain adhesive naturally falls off. In the process of cleaning, it is necessary to see if there are any fragments of ancient porcelain left in the sediment in the cleaning machine. If there is, it should be confirmed to be consistent with the equipment after cleaning, and then the fragments should be used to be as original as possible. Wash the black in the punch first. If there is no ultrasonic cleaner, drip chlorine-containing disinfectant on the hole, and aim the blower at the hole to speed up the volatilization of the medicine. Generally speaking, this process has to be repeated many times before the black marks on the production line can be completely washed off and then rinsed with clean water. Sometimes, because it's dark and difficult to wash, this step will take several days.
2. Make repairs. Generally, 502 glue or two-component epoxy resin is used to bond and repair ancient porcelain tiles, which are colorless and transparent. Porcelain mud made of porcelain powder and synthetic materials (polyester) is used to fill the gaps. After the ancient porcelain is assembled, fill the background color, draw blue and white, and glaze. Glaze is a new kind of imitation glaze coating, such as polyester. After glazing, the surface of the vessel is bright, hard and decorative. Sometimes, the blue and white lines along the mouth are deep in the middle and light on both sides, just like the ink clouds in Chinese painting, looming and empty. He said that when dealing with the edge of the mouth, we should choose a combination of manual drawing and mechanical spraying to achieve seamless. Finally, cover the lamp with floor wax. The restored ancient porcelain is as bright as ever and reappears its original appearance.
Second, the selection method of ceramics
1. Selection of wall tiles: tiles are divided into five grades according to quality: excellent, first-class, second-class, third-class and out-of-class. It should be noted that only clear and standardized building materials production licenses, product certificates, trademarks and quality inspection labels can be considered authentic. Colors and patterns can be decided according to personal preference.
2. Then the glazed tiles with good quality should be smooth and delicate, the glossy glaze should be crystal clear and shiny, and the matte glaze should be soft and comfortable. When the brick is placed at a distance of 1 m, no obvious glaze defects should be seen under sufficient natural light or fluorescent light. The breeding method of Chinese rose is very important! Pattern brick pattern should be delicate and realistic, without obvious defects such as lack of color, broken line and dislocation. The shading and trademarks on the back of high-quality ceramic products are clear and complete, with few glaze marks or defects.
3. Selection of wall tiles: The whiter the tiles, the brighter the better. In order to pursue the effect of natural marble and white marble, some manufacturers of porcelain polished tiles usually add zirconia raw materials to the formula, which is highly radioactive.
Ceramics are tiles with high utilization rate, good texture and many people like them. Then the method of ceramic repair technology and how to choose ceramics, I think everyone knows through the introduction of the above small series.
