This invention discloses a green environment-friendly removing device for porcelain glaze based on defective enamels, including a main body, a reaction cavity with an upward opening formed in the main body and a supporting plate slidably arranged between the inner walls in the reaction cavity, and an enamel residual product can be placed on the supporting plate, and a porcelain glaze removing mechanism capable of enabling the enamel residual defective product to generate chemical reaction and remove the porcelain glaze is arranged in the reaction cavity, has a very optimized reworking effect; does not need a mechanical reworking process and does not need to worry about the pollution environment, so that the porcelain glaze removal process of the whole enamel defective product is simple and trouble-saving; some wastes generated after processing can be collected and utilized, and all generated waste liquid wastes can reach emission standard and green and environment-friendly.

Coating plate in ceramic material for outdoor application, obtaining method and use thereof. The ceramic coating plate for outdoor application comprises a vitreous layer wherein the vitreous layer comprises 3-30% (m/m) of an infrared reflective pigment, wherein the infrared reflective pigment comprises titanium dioxideTiO.sub.2.

Said plate provides the user with thermal comfort in contact between the plantar surface of the feet and the ceramic material and may also be used in the coating of faades, or upper coverings.

TiO.sub.2 concentration may be 5-25% (m/m), 8-20% (m/m), or 9-11% (m/m). TiO.sub.2 particles have a size between 0.1-2 m, more preferably 0.25-2 m. The infrared reflective pigment may further comprise metal oxides Al.sub.2O.sub.3, SiO.sub.2, MnO, SbO, Fe.sub.2O.sub.3, or mixtures thereof.

Said plate may be a tile, a ceramic, a mosaic, a paving block or a slab, among others.

A 3D printing system may print a desired 3D object. A fusible powder may fuse when subjected to a fusing condition. A deposition system may deposit portions of the fusible powder on a substrate. A fusing system may apply the fusing condition to the deposited fusible powder. Inhibitor material may not fuse when subjected to the fusing condition. An insertion system may insert a portion of the inhibitor material between portions of the deposited fusible powder after having been deposited by the deposition system, but before being fused by the fusing system, so as to form a boundary that defines at least a portion of a surface of the desired 3D object.
