Embodiment 1
[0098] 1. Preparation of front glass glaze (in contact with water): mix 72% SiO 2 , 3%Al 2 o 3 , 14% B 2 o 3 , 5%Na 2 O, 5.5% CaO, 0.5% SiC, mixed evenly, kept at 1650°C for 1 hour, then water quenched to obtain transparent glass slag, dried, crushed, and passed through a 250-mesh sieve to obtain a powder with an average particle size of 1.5-2.5 μm body.
[0099] 2. Preparation of front glass glaze coating: mix the front glass glaze powder and organic carrier evenly according to the ratio of 73:27, and pass through a three-roll mill to obtain a viscous fluid with a viscosity of 30-70 Pa.S and a fineness of less than 12 μm .
[0100] 3. Preparation of back glass powder (printed circuit): 77% SiO 2 , 3%Al 2 o 3 , 14% B 2 o 3 , 5%Na 2 O, 0.5% CaO, mixed evenly, kept at 1650°C for 1 hour, then quenched in water to obtain transparent glass slag, dried, crushed, and passed through a 250-mesh sieve to obtain a powder with an average particle size of 1.5-2.5 μm.

Abstract
The invention discloses a non-metallic heating device for cooking. The non-metallic heating device for cooking comprises a non-metallic pot body and a heating base, wherein the heating base comprisesa ceramic heating plate, at least one glass functional coating is formed on the surface of the ceramic heating plate, the ceramic heating plate and the non-metallic pot body are formed into an integrated structure through the glass functional coatings, and each glass functional coating partitions food in the non-metallic pot body from the ceramic heating plate; each glass functional coating is prepared by sintering glass glaze at 750-1200 DEG C. The non-metallic heating device for cooking has the advantages that a heating device body is completely made from nonmetal, and the non-metallic heating device is low in cost, long in service life and safe, can be produced in batch and is easy to clean.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a non-metal heating device for cooking. Background technique [0002] Kettles are a necessity of life. From gas-fired kettles to smart plastic electric kettles, to stainless steel electric kettles, to half-glass kettles, and all-glass kettles, products are constantly being updated. The physical properties of glass are stable, safe, and clean. It will not chemically react with heated food, and there will be no hidden worries of heavy metals. The transparent body of glass can penetrate far-infrared rays to improve water quality and optimize water sources. [0003] The current all-glass kettle generally has several technologies: transparent nano-film, carbon film and thick film. The former two types have fast power attenuation and have been abandoned by various manufacturers. The latter has good power stability, but has high process requirements and strict requirements...
