摘要

#CMT# #/CMT# Sanitary unit comprises a base body (1) made of a metal, preferably steel, which is provided with an enamel layer. The enamel layer of base body side comprises base layer of a base enamel (2), on which a coating layer of a cover enamel (3) is applied, where the enamel layer is provided with the sanitary tub exhibiting an impact resistance of at least 35 N. #CMT# : #/CMT# An independent claim is also included for obtaining the above mentioned sanitary device, comprising (i) applying a base slurry to the base body of the sanitary unit, (ii) applying a cover slurry on the base slurry, where the cover slurry include the reinforcing agent (5-35 wt.%), and (iii) drying and heating or burning of the base body coated with the base slurry and the cover slurry, where the base enamel of the base layer from the base slurry and the cover enamel of the cover layer form the cover slurry are obtained by heating. #CMT#USE : #/CMT# Used as a sanitary unit. #CMT#ADVANTAGE : #/CMT# The sanitary unit exhibits high impact and scratch resistance. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a cross section of a base body of a sanitary unit coated with a base enamel and cover enamel. 1 : Base body 2 : Base enamel 3 : Cover enamel 4 : Corundum particles #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Components: The cover enamel (3) comprises at least one reinforcing agent (5-35 wt.%). The reinforcing agent is located only in the cover enamel. The sanitary device includes ceramic balls with an average diameter of 0.8-1.2 mu m as a reinforcing agent. The ceramic balls include feldspar and/or silicon dioxide. The sanitary device includes corundum particles (4) with an average diameter of 15-30 mu m as a reinforcing agent. The base enamel includes at least one salt including quartz, feldspar, borax, titanium dioxide, sodium carbonate, potassium carbonate, fluorite, calcite, nickel oxide, cobalt oxide, manganese oxide or metal phosphate. The cover enamel includes at least one salt including quartz, feldspar, borax, titanium dioxide, sodium carbonate, potassium carbonate, lithium carbonate, fluorite, calcite or metal phosphate. The weight percent of reinforcing agent contained in the cover enamel is adjusted, such that the coated sanitary tub with the enamel layer withstands an impact test with a potential of at least 50 N, preferably 70 N without damage.
