[0044] Sanitary Ware and Bodies

[0045] In this manual, "sanitary earthenware" refers to toilets, washbasins, and pottery products used around them, and specifically refers to toilets, urinals, water tanks, floor drains (sana), washbasins, hand washing devices, etc. . The sanitary pottery of the present invention is preferably pottery whose material is described in "7.1 Types of Materials" of JIS A5207:2019 and which satisfies various characteristics described in "7.2 Quality of Pottery".

[0046] The body of the sanitary pottery of the present invention is basically a pottery body of vitrified porcelain. In this specification, the term "vitrified porcelain body" has the general meaning understood in the technical field related to sanitary ware. The "pottery body" is understood to have a general meaning except that it has the characteristics of the present invention described later.

Abstract

Provided is a sanitary pottery having both low water absorbency and light weight. The sanitary pottery is provided with a vitrified porcelain pottery body and a glaze layer, a part of the body is not provided with the glaze layer and is exposed to the outside, the body contains (A) anorthite and (B) an alkali metal component, and the amount of the alkali metal component is 5-10 wt% in terms of oxide (A2O) relative to the body.

Description

technical field [0001] The present invention relates to sanitary ceramics used in toilets, washbasins and the like. Background technique [0002] Sanitary pottery is much heavier than tableware, so if you use porcelain with a lot of glass, it will be severely deformed by its own weight during firing, making it difficult to manufacture. On the other hand, if pottery with less glass and more crystals is used, water absorption will occur in the unglazed part. Therefore, problems such as absorption of sewage and damage due to freezing damage may occur. Therefore, sanitary pottery uses a vitrified porcelain body that is placed between porcelain and pottery, suppresses deformation during firing, and minimizes water absorption. [0003] That is, at present, sanitary ware generally has a vitrified porcelain body and a glaze layer, and the glaze layer is formed on most of the vitrified porcelain, and a part of the vitrified porcelain is exposed. structure. For example, when sanit...
