A enamel-free paste for use especially in ovens at temperatures of up to about 420° C. The paste contains a matrix based upon a silicon (Si) polymer that can be obtained by the hydrolysis and condensation of at least one silane of general formula RxSi(OR′)4-x with at least one polysiloxane of general formula [R2SiO]y, or R3Si—(O—SiR2)y—O—SiR3. The radicals R can independently be alkyl, aryl,arylalkyl, alkylaryl or H; the radicals R′ can independently be H, methyl,ethyl, n- or i-propyl, n-, iso-, sec- or tert-butyl; x represents 0 or 1 (for the first silane); x represents 0, 1, 2, 3, or 4 (for each subsequent silane); and y represents a whole number, which is at least 2 and can be approximately infinite. The paste additionally includes a high-boiling organic solvent with a boiling point of 100° C. or above, and a pigment as the solvent, but does not include alcohol with a boiling point of below 100° C.

摘要:
A cooking appliance having a cooking space with a micro-rough surface. The micro-rough surface is formed on a metal substrate. In order to better clean the micro-rough surface from dried or charred food material, the layer includes an enamel formed of a glass flux with separate crystal zones spaced from one another formed and embedded in the enamel. The crystal zones are formed by crystallizing portions of the enamel into crystalline phases, forming a rough superstructure with a plurality of fine structures on the surface of the superstructures.
摘要:
A baking oven includes a metallic baking oven muffle that can be closed off on a front side by a door. The muffle walls have heating elements for heating the cooking chamber to over approximately 180° C. and/or for heating the food disposed therein to be cooked. The muffle has a protective layer covering the muffle walls at least on the inner side. To improve the use properties of the baking oven muffle, the thickness of the protective layer is less than approximately 30 &mgr;m. The protective layer is formed as a hard sol-gel layer having a thickness of approximately 10 &mgr;m, preferably, between approximately 5 and 10 &mgr;m. The protective layer is transparent. The inner sides of the muffle serve as a reflector. A functional sol-gel layer is disposed on the hard sol-gel layer. The functional sol-gel layer has a thickness of approximately 10 &mgr;m, preferably, 2 to 3 &mgr;m. When the muffle is aluminum, the protective layer is an anodized aluminum oxide layer. The heating elements are applied to an insulating protective layer with thick-film technology. A stabilizing frame is substantially formed by the baking-oven muffle insulation. The frame supports the muffle on its outside. A muffle wall thickness is approximately 0.3 to 0.5 mm, preferably, 0.4 mm. Protective layer thickness is less than 20 &mgr;m, preferably, between approximately 5 and 10 &mgr;m.
