Abstract
The invention discloses a making technology and coating formulas of colorful enamel gas stove surfaces. The making technology comprises the steps of preprocessing, and four enameling and four burning, and formulas of a colorized glaze comprise a green formula, an orange-colored formula, a carmine formula, a bright red formula, a nonluminous orange-colored formula and a pearlescent effect coating formula. According to the invention, static dry powder and wet spraying are mixed and the four enameling and four burning is carried out to produce the enamel gas cooker surfaces with various colors and solve problems of deformation, enamel cracking and the like of traditional enamel stove surfaces, so the product grade is greatly improved. The enamel stove surfaces made in the invention have the characteristics of attractive appearance, abundant color and pearlescent effect possessing; compared with stainless steel stove surfaces, the enamel stove surfaces have the advantages of easy cleaning, scratch resisting and low cost; and compared with glass stove surfaces, the enamel stove surfaces have the advantages of no generation of an explosion phenomenon, and substantial improvement of the safety performance.
Description
Technical field:
The present invention relates to a kind of manufacture craft of gas-cooker face, especially relate to a kind of manufacture craft of the colorful porcelain enamel gas-cooker face with pearl effect and the coating formula of enamel kitchen range face.
Background technology:
The gas-cooker face of main flow is mainly take stainless steel and glass bi-material as main in the market.Glass gas-cooker face is having certain advantage aspect the property easy to clean of product, still due to the characteristic of glass itself, has certain self-destruction rate, therefore has very large potential safety hazard; Stainless steel gas-cooker face is compared glass gas-cooker face, although there is not the security hidden trouble of self-destruction, has that cost is high, not easy to clean, the shortcoming such as scrape resistant not.And traditional enamel product modes such as ward off of soaking that adopt cause enamel layer in uneven thickness more, the problems such as orange peel, pin hole, sudden and violent porcelain easily occur; And traditional enamel kitchen range face texture is relatively poor, and color is single, and the class of goods is on the low side.At present on the market enamel gas-cooker face mostly is wet shot or electrostatic dry powder enameling process, is generally one and wards off one and burn or two ward off two burnings.If sintering number increases, will produce the phenomenons such as distortion, sudden and violent porcelain.But because colored enamel kitchen range face needs at least three sintering, therefore only have in the market two kinds of products of black and white.
Summary of the invention:
The invention provides a kind of manufacture craft of colorful porcelain enamel gas-cooker face and the coating formula of enamel kitchen range face, to solve the weak point of above-mentioned existing stainless steel kitchen range face, range glass top and traditional enamel kitchen range face.
