Description
Technical Field
The invention relates to the technical field of water purification filter element sleeve processing, in particular to a porcelain coating process for the inner and outer surfaces of a water purification filter element sleeve.
Background
At present, no matter large-scale water purification equipment or household water purification equipment, the problems of secondary pollution of water quality caused by corrosion, rust and the like after long-time use of the water purification filter element sleeve exist, and the following reasons are considered: the existing water purification filter element sleeve basically adopts 304 stainless steel as a base material, the 304 stainless steel is not rusted, but when the water purification filter element sleeve is processed, a welding line is generated on the cylinder body, a water inlet and a water outlet are connected through a water tap, the joint is also required to be welded, the welding point is high in temperature during welding, the welding point is changed in quality during welding, the welding points are corroded and rusted for 2-3 years, the secondary pollution of water quality is caused, and even in areas with poor water quality, the corrosion and rusting and perforation are caused, and equipment is scrapped.
In order to solve the above problems, the water purifier industry generally adopts modes of electroplating, plastic spraying, enamel and the like on the inner surface and the outer surface of the water purifying filter element sleeve, but the water purifier has the defects: electroplating cannot completely and effectively solve the problems of rust and corrosion, and the coating also has heavy metal pollution, environmental protection influence and high processing cost; the problem of rust can be effectively solved in the aspect of plastic spraying, however, certain water pressure exists in the water purification filter element sleeve, internal and external pressure difference is generated during regular flowing, the plastic spraying coating can age and fall off about 2 years, and plastic products are soaked with water for a long time, and plastic agents enter the water, so that the method is not popularized in the industry; enamel aspect: the enamel can effectively solve the problem of rust, but because the water purification filter element sleeve needs to be edge sealed by a coating without dead angle, the enamel cannot be edge sealed (the edge of a port of stainless steel or iron and the thickness of a material are not covered with the enamel), and moreover, a saw-tooth edge can be formed when a metal piece of the surface enamel is cut, so the problem is not solved in the enamel industry at present. In addition, to facilitate cleaning and replacement of the cartridge, the water purification cartridge sleeve generally comprises a cartridge body and a cartridge cover of split design, while to ensure that the junction of the cartridge body and the cartridge cover is impermeable to water, a metal hoop is generally adopted to forcefully compact the junction of the cartridge body and the cartridge cover, and enamel is not subjected to such pressure, so that the water purification cartridge sleeve has not been widely popularized.

According to the porcelain coating process, the glaze raw material is ground into 200 meshes of fineness, the fineness can effectively permeate surface micropores of metal, and after inorganic matters are ground into a thickener, if only raw materials of traditional enamel are used, the surface is fragile, the 200 meshes of water powder can be more uniform by adding peach gum, the uniform time of the water powder can be kept longer by adding the glutinous rice gum without precipitation, and urea is added, so that in the process of firing a coating, the volatilization of bubbles in the coating is accelerated, the bubble point on the surface is eliminated, and the yield is improved.
The glaze firing temperature is over 800 ℃, inorganic matters are melted at high temperature, and organic matters (peach gum, glutinous rice gum and urea) are burnt out and disappear at high temperature, but the physical properties of the raw materials generated by the organic matters are not yet disappeared when the glaze raw materials are melted and reacted within three minutes due to short firing time. The peach gum is prepared by mixing a small amount of raw materials into the porcelain glaze, and rapidly cooling to recover the normal temperature within three minutes to form a glaze layer.
In summary, the invention combines the glaze raw material with the surface of the metal matrix at 800-900 ℃ and cools and solidifies, the coating solves the problem which is not solved all the time in the water purification industry, namely the problem which can not be solved by the traditional enamel coating.
Secondly, the water purification filter element sleeve is formed by combining a cylinder with a cover, the pressure of the combining part is high, the traditional enamel cannot be broken by the pressure, and the coating processed by the technology is repeatedly tested for many times, so that the combining part can bear the pressure and meets the requirement of water purifier equipment without damage and breakage.
The bonding strength between the coating processed by the technology and the metal matrix is tested by experiments, and the cutting tool is used for cutting, so that the edge porcelain layer at the cutting position is not fallen off and is exploded. Traditional enamel cannot be cut, and the porcelain is broken and cracked after cutting.
Through the impact experiment, the traditional enamel coating can form larger circles or irregular damages at impact points, and the coating processed by the technology is not diffused at the impact points.
Therefore, the coating processed by the technology has the essential difference from the traditional enamel in terms of the bonding strength between the coating and metal, compressive strength, tensile strength and impact strength, and has wider application range.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered by the scope of the claims of the present invention.
