[0059]The pH value is very critical to the preparation of ceramic coatings. The performance and service time of ceramic coatings will be very different when reacting at different pH values. In order to ensure the accuracy of the pH value during the system reaction, the amount of organic acid added to the catalyst must be accurate. It works, because the catalyst organic acid is added in a small amount in the paint, adding it alone will easily cause a large error, and the pH value of the reaction will have a large error. Adding it after diluting it with deionized water can reduce the error of catalyst addition, which is beneficial The control of the pH value of the ceramic coating reaction enables the ceramic coating to achieve the desired performance.

Abstract

The invention discloses a ceramic coating for the surface of an energy gathering ring of a gas stove and a preparation method and an application method of the ceramic coating. The ceramic coating comprises the following components in percentage by mass: a component A, namely, 67.5-69.5% of color paste; a component B, namely, 30.5 to 31.5% of silane; and a component C, namely, 0.7-0.8% of a catalyst. The ceramic coating of the invention solves the problems of poor temperature resistance and easy decomposition and discoloration during combustion of an organosilicon coating on the surface of theenergy-gathering ring of the gas stove, has the characteristics of good high temperature resistance, no decomposition and discoloration at high temperature and no release of smoke, and is very suitable for being used as a surface coating of the energy-gathering ring of the gas stove.

Description

technical field [0001] The invention relates to a ceramic coating for the surface of an energy-gathering ring of a gas stove, a preparation method and an application method thereof. Background technique [0002] The energy-gathering ring of the gas stove has two main functions: one is to gather the flame to prevent heat loss and greatly improve thermal efficiency; the other is to achieve the effect of wind protection, preventing the wind from blowing out the flame and keeping the flame burning stably. [0003] Gas stove energy gathering rings are generally made of cast iron or stainless steel. Although they can work continuously at a higher temperature of 800°C, if there is no coating protection, the surface will be oxidized and discolored after a period of use, which not only affects the appearance, but also Affect the service life of the energy-concentrating ring. [0004] In order to protect the energy-gathering ring of the gas stove from being oxidized and discolored, t...
