Problems solved by technology

[0003] The disadvantage of the surface processing technology of the shell series is that the change of the spraying sequence of the existing protective glaze and shell dry particles leads to the impact of the subsequent polishing process on the rock plate, so that there are too many convex gaps on the polished surface, and the application is not only insufficient. Delicate, the product is easy to hide dirt during use, which is inconvenient for hygiene

Embodiment

[0020] A shell series surface processing technology, comprising the following steps:

[0021] Step 1. Send the finished bricks to the box-type waste heat drying kiln installed in front of the firing kiln, extract the waste heat from the tail of the firing kiln to heat the drying kiln, and then use the automatic temperature measuring gun to test that the temperature in the drying kiln is 65 -75°C, keep the temperature and continue to dry for 20-30 minutes to complete the drying of the adobe. Finally, after testing, if the moisture content in the adobe is less than 0.7% of the total mass of the adobe, proceed to the next step of processing. If the content is greater than 0.7% of the total mass of the adobe, it will be returned to be dried and dewatered again;

[0022] Step 2. The dry and dewatered bricks in step 1 are replenished with water through the water spray cabinet, so that the surface of the bricks is moistened, which is conducive to the combination of the glaze and the ...

experiment example

[0032] The weather resistance of the surface of the slate is tested as shown in the following table:

[0033]

[0034] According to the above experiments, not only the glossiness of the surface of the rock slab of the present invention meets the requirements, but also its antifouling effect and hardness also meet the requirements.

[0035] The technical effect of the present invention is mainly reflected in the following aspects: the brick adobe laid by the press is dried for the first time to remove the free water inside, the moisture content in the adobe is controlled to be less than 0.7% of the total mass of the adobe, and the adobe is dried after it leaves the kiln. Spray water mist on the surface, then spray the bottom glaze on the surface of the green body, and then spray the pattern with an inkjet machine, spray the protective glaze and dry shells in sequence after drying in the drying kiln, and then go into the kiln for firing after the second drying in the drying ki...

Abstract

The invention discloses a shell series surface processing technology, which comprises the following steps: carrying out primary drying on a green brick pressed by a press to remove free water in the green brick, controlling the moisture content in the green brick to be less than 0.7% of the total mass of the green brick, spraying water mist on the surface of the green brick after the green brick is taken out of a drying kiln, spraying ground coat on the surface of the green brick, and drawing patterns by an ink jet printer; performing drying in a drying kiln, sequentially spraying protective glaze and shell dry particles, carrying out secondary drying in the drying kiln, putting the dried product into a firing kiln, performing firing at a high temperature of 1196-1205 DEG C for 60-70 minutes, sequentially carrying out rough polishing, medium polishing and fine polishing, and finally performing detecting to apply the qualified rock plate to furniture assembly, house decoration and the like. On the premise of reducing the cost through a specific treatment method, the surface of the rock plate is polished uniformly, the glossiness of the surface is uniform, the antifouling property ofthe surface is excellent, and the touch feeling of the surface is soft.

Description

technical field [0001] The invention specifically relates to a shell series surface processing technology. Background technique [0002] Modern architecture and decoration industry are using more and more imitation natural stone bricks, and the requirements for imitation natural stone bricks are becoming more and more wild. Various types of imitation natural stone bricks are also emerging in large numbers. The porcelain polished bricks currently on the market All of them are produced by "dream fabric", "multi-tube fabric" and "micro-powder multiple fabric". [0003] The shortcoming of the surface processing technology of the shell series is that the change of the spraying sequence of the existing protective glaze and shell dry particles leads to the impact of the subsequent polishing process on the rock plate, so that there are too many gaps between the bumps on the polished surface, and the application is not only insufficient. Delicate, the product is easy to hide dirt du...
