Background
In recent years, a ceramic tile with main fine texture such as silk glaze, skin glaze, velvet, golden velvet and the like is ignited by virtue of fine handfeel, soft vision and Gao Yanzhi, and is deeply favored by young consumers, the technical problems of uneven surface caused by glaze spraying are solved mainly by spraying fine smooth glaze, increasing the using amount of flux in the glaze and the like at present, but the ceramic building industry enters a quality improvement and price matching stage at present, various solid wastes are doped in a blank for controlling production cost, and volatilization of organic matters and impurities in the solid wastes easily causes glaze defects, so that the ceramic tile production process with both matte and fine and smooth handfeel is unstable, the surface effect is difficult to control, and especially the defects such as surface pinholes and orange peel are displayed to be clear when the ceramic tile with deep color texture is produced, and the fine ceramic tile with fine texture on the market is mainly in a light color system at present.
On the other hand, because the extremely competitive terminal market is characterized by representing different products, different manufacturers generally popularize ceramic glazed tiles with products of a certain similar texture to obtain market acceptance, the ceramic glazed tiles are expressed in analog or descriptive language, different people have different senses and are difficult to uniformly and qualitatively, the market is disordered and clustered, glaze texture is difficult to objectively express in the technical field when glaze is developed, and the subjective expression products bring the difficult problem of difficult stable control to technical research, development and production.
The invention patent CN116023171A provides a ceramic plate with skin-friendly texture, and a preparation method and application thereof. The ceramic plate can realize a surface matte effect, a soft and comfortable visual effect and a surface roughness Ra=10-15 mu m through the mutual matching of the multiple glaze layers, and the expression of the invention is that the surface is fine and smooth like the skin of an infant, and accords with the skin-friendly texture of human engineering. In fact, when the roughness Ra=10-15 mu m, the surface roughness is stronger, the surface is finer and smoother like the skin of an infant, which is described in the patent is more difficult to obtain, and the surface roughness of the glaze with different formulas and different textures is detected, when the Ra is smaller than 2.0 mu m, the texture of the glaze is finer and smoother, the lower the roughness is, the finer and softer the surface is, and most of the roughness Ra of the glaze products in the ceramic building industry is difficult to break through and is lower than 1.20 mu m.
