Glass inner liner for rice cooker and manufacturing method for glass inner liner

Abstract

The invention discloses a glass inner liner for a rice cooker, which is formed by using silicon dioxide as a basic raw material and being matched with aluminium oxide, sodium oxide, lithium oxide and boron oxide, and the raw materials have the weight percentages: 78 to 81% of the silicon dioxide, 1 to 3% of the aluminium oxide, 3 to 5% of the sodium oxide, 0.1 to 1% of the lithium oxide and 13 to 16% of the boron oxide. The manufacturing method for the glass inner liner for a rice cooker comprises the steps of: A. proportionally preparing all the raw materials; B. evenly mixing the prepared raw materials by a mixer; C. sending the evenly mixed raw materials into a melting tank, and heating the raw materials to a temperature of 1300 to 1800 DEG C to form glass melt; D. sending the glass melt into a clarifying tank so as to be subjected to clarification and homogenization processing; and E. sending the clarified and homogenized glass melt into a forming press mould so as to be made into a finished product. The glass inner liner manufactured by adopting the process has the advantages of high-temperature resistance, attractive appearance and convenience for cleaning, meanwhile, glass products also meet the requirements on people and present society for the aspects of health and environmental friendliness, and the like of a product.

Description

technical field [0001] The invention relates to a glass liner for an electric rice cooker and a manufacturing method thereof. Background technique [0002] The rice cooker liners currently on the market are usually made of aluminum, iron, stainless steel and other materials, but the surface of the rice cooker liners made of these materials must be surface treated and sprayed. When used for a long time, The sprayed coating on the surface will fall off and fade, which is neither hygienic nor beautiful, and does not meet the requirements of people in today's society for environmental protection and health of products. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a glass liner for electric rice that can withstand high temperature, is easy to clean, and is hygienic and environment-friendly and a manufacturing method thereof. [0004] The technical solution adopted by the present invention to solve its...
