Membrane production technology to prevent the soil from leaking out from the loess board and to control the permeability of oil

摘要

The present invention relates to an improvement of a loess board, and more particularly, to a method for improving a loess board by using various kinds of foods including fishes and meat, when cooking with a loess plate made of loess, To a technique for manufacturing a film capable of controlling the absorption of liquid.;For this purpose, sodium silicate water glass is applied on the surface of the loess plate formed by using a hydraulic press machine, and the sodium silicate film is formed on the surface of the loess through the steps of drying and heat treatment.;By forming the irregular sodium silicate glass film on the surface of the loess board according to the present invention, it is possible to prevent the soil from coming out during the cooking using the loess loess board. By adjusting the mixing ratio of water glass and water, the thickness of the sodium silicate glass film can be controlled, The degree of absorption of the soup from the food can be controlled. In addition, since the sintering of the loess board is performed by heating at a high temperature of 400C, the strength of the whole baking plate is strengthened.
