Embodiment 1
[0035]This embodiment provides a thin ceramic plate with good antifouling effect and its manufacturing method.
[0036] A ceramic thin plate with good antifouling effect comprises from bottom to top: a primer layer, a fabric layer and a decorative protective layer. The fabric layer includes a permeable layer formed of an organic liquid material with a thickness of 0.3-0.6 mm; the decorative protective layer is a glassy substance formed after melting and cooling of dry particles or frit layer after high-temperature firing. The adobe with the above structure can be polished smoothly after sintering because the permeable layer has a certain thickness, and the dry particles or frit layer with a thickness of 0.2-0.5 mm are added to the glassy substance formed after melting and cooling after high-temperature firing. And the decorative pattern formed by the permeable layer is also particularly wear-resistant.
[0037] Of course, the scheme of the present invention can also be adopte...
Embodiment 2
[0062] The difference between this embodiment and Example 1 is that the inkjet printing methods of the penetrating glaze ink and the penetrating agent ink are different, and the drying treatment is also carried out in this embodiment; Sub-high temperature firing. In this embodiment, the organic penetrating glaze ink is repeatedly printed, while the organic penetrating agent ink is sprayed instead of inkjet printing. Of course, there are simpler methods such as roller printing and screen printing to perform inkjet printing of the penetration aid ink, and the above methods can all achieve the same effect. However, from the perspective of process controllability, especially for the formation of specific patterns, inkjet printing is still the preferred way of dispensing glaze ink and penetration enhancer ink.
[0063] In the prior art, after inkjet printing, it will be fired directly in a kiln, which is for water-based penetrating agents. However, this scheme uses organic penetr...
Embodiment 3
[0065] It has been introduced in the summary of the invention that in order to obtain the ink-jet ceramic thin plate with a matte surface effect, it is basically the same as in Example 1, the difference is that after the semi-finished product in Example 1 is fired, the soft polishing is changed by known technology. Combination of eye numbers can achieve matt products with a glossiness in the range of 5-30 degrees. Matte products have a more high-end decorative effect, which can give the product better added value. Moreover, the product with matte effect can avoid the bottom-through phenomenon caused by over-polishing because of its less polishing amount.
