[0003] The purpose of the present invention is aimed at the actual application of the glaze for enamelled steel plates for biogas, and the enamel formulations of existing steel plate enamel products cannot be effectively applied to the production of glazes for enamelled steel plates for biogas, and the cost is relatively high or the process is relatively slow. Complicated and unable to meet the requirements of the glaze for biogas enamel steel plate, and provide a kind of enamel for biogas enamel steel plate and its application. According to the requirements of normal reaction, when the pH value is lower than 6 or higher than 9, the properties of the glaze body are still stable, suitable for the growth and reproduction of microorganisms in the biogas tank; it can be used for many years, the cost is low, and the process is simple

The invention relates to a porcelain glaze of an enameling sheet for marsh gas and application thereof. The porcelain glaze consists of a base glaze and a face glaze. The base glaze is melted at the temperature of 1,150 DEG C, sprayed onto a steel plate of which the thickness is 3 to 10mm after ball milling and fired for 5 to 15 minutes at the temperature of 880 DEG C; and the face glaze are melted at the temperature of 1,100 DEG C, sprayed onto a steel plate coated with a base glaze blank after ball milling and fired for 5 to 15 minutes at the temperature of 860 DEG C to obtain the enamelingsheet for the marsh gas. The porcelain glaze has the advantages that: requirements of normal gas generating reaction in a marsh gas tank of which the pH value is between 6 and 8 can be met; the performance of the glaze is still stable when the pH value is lower than 6 or higher than 9; the porcelain glaze is suitable for the growth and propagation of microorganisms in the marsh gas tank; and the porcelain glaze can be used for years and has a low cost and simple process.
Description
technical field [0001] The invention relates to an enamel of an enamel steel plate for biogas and its application. Background technique [0002] With the continuous development of new enamel products, various new technologies and new processes emerge in an endless stream, and the scope of application of enamel products is getting wider and wider. Assembling biogas generating pools with enamel steel plates is one of them. In various enamel products, the performance emphasis of the required enamel glaze is also different. For example, daily-use enamel products are required to be non-toxic and beautiful, but they cannot meet the requirements of biogas reaction conditions. The glaze for industrial reactor enamel mainly has the characteristics of acid resistance, alkali resistance and long service life, but for the glaze for enamel steel plate for biogas, the cost is high and the process is relatively complicated.
