Description
Technical Field
The invention relates to the technical field of water purification filter element sleeve processing, in particular to a process for coating porcelain on the inner and outer surfaces of a water purification filter element sleeve.
Background
At present, no matter be large-scale water purification unit or domestic water purification unit, all there is water purification filter core sleeve to appear after using for a long time corroding, rust etc. and cause quality of water secondary pollution's problem, its reason is as follows: present water purification filter core sleeve all adopts 304 stainless steel as the substrate basically, 304 stainless steel is not rusty itself, but when processing water purification filter core sleeve, the stack shell can produce the welding seam, water inlet and delivery port have tap to be connected in addition, and the junction also need to weld, and the welding spot can produce high temperature during the welding, make the welding take place the matter change when welding, these welding spots will corrode and rust in 2 ~ 3 years, cause quality of water secondary pollution, what is more, in the poor area of quality of water, 2 ~ 3 years will corrode and rust the perforation, cause equipment to scrap.
In order to solve the problems, the water purifier industry usually adopts the modes of electroplating, plastic spraying, enamel and the like on the inner surface and the outer surface of a water purifying filter element sleeve, but the modes have respective disadvantages: the problem of rusting and corrosion cannot be completely and effectively solved by electroplating, the coating is also polluted by heavy metal, and the environmental protection influence and the processing cost are high; the problem of rusting can be effectively solved in the aspect of plastic spraying, but a certain water pressure exists in the water purification filter element sleeve, an internal and external pressure difference is generated during frequent flowing, a plastic spraying coating can age and fall off in about 2 years, and a plastic agent also enters water when a plastic product is soaked in water for a long time, so that the method is not popularized in the industry; enamel aspect: the rust problem can be effectively solved by enamel, but because the water purification filter element sleeve needs the coating banding at no dead angle, and enamel can not be banded (stainless steel or iron port edge and the thickness of material can not be covered by enamel), moreover, the metalwork of surface enamel can form the cockscomb structure edge when the cutting, and this problem is not solved in the enamel industry at present. In addition, in order to facilitate cleaning and replacement of the filter element, the water purification filter element sleeve usually comprises a cylinder body and a cylinder cover which are designed in a split mode, and in order to ensure that the joint of the cylinder body and the cylinder cover is not water-permeable, the joint of the cylinder body and the cylinder cover is usually strongly compacted by a metal hoop, and enamel cannot bear the pressure, so that the pressure is not expanded.

The application of the porcelain-applying process grinds glaze raw materials into 200 meshes of fineness, the surface micropores of metal can be effectively permeated by the fineness, inorganic substances grind the thickening agent, if only traditional enamel raw materials 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 more lasting by adding glutinous rice gum, the glutinous rice gum does not precipitate, urea is added, and in the process of firing a coating, the volatilization of bubbles in the coating is accelerated, the surface bubble points are eliminated, and the yield is improved.
The glaze firing temperature exceeds 800 ℃, so that inorganic matters are dissolved at high temperature, organic matters (peach gum, glutinous rice gum and urea) are burnt out at high temperature and disappear, but the physical properties of the raw materials generated by the organic matters are not disappeared when the glaze raw materials are melted to generate reaction within three minutes because the firing time is short. The peach gum is melted into the porcelain glaze by a small amount of raw materials, and is taken out within three minutes and rapidly cooled to return to the normal temperature, and then a glaze layer is formed.
In conclusion, the glaze raw material is combined with the surface of the metal substrate at 800-900 ℃, and is cooled and solidified, the coating solves the problem which is not solved by the water purification industry, namely the problem which cannot be solved by the traditional enamel coating, and firstly, the traditional enamel coating cannot seal edges on the metal substrate, namely the edges of stainless steel, the traditional enamel cannot cover, and places which cannot be covered become corrosion rust spots.
And secondly, the water purification filter element sleeve is a cylinder and is combined with the cover, the pressure of the combined part is large, the traditional enamel cannot be broken due to the pressure, the coating processed by the technology is not broken through repeated experiments, and the combined part can bear the pressure, so that the requirement of the water purifier equipment is met.
The bonding strength of the coating and the metal matrix after the processing by the technology is tested by experiments, the cutting tool is used for cutting, and the ceramic layer at the edge of the cutting part does not fall off and has the phenomenon of ceramic explosion. The traditional enamel cannot be cut, namely, the cutting breaks porcelain and cracks.
Through the impact experiment, the traditional enamel coating can form a large circle or irregular damage at an impact point, and the coating processed by the technology has no diffusion at the impact point damage point.
Therefore, the coating processed by the technology is essentially different from the traditional enamel in the bonding strength, the compressive strength, the tensile strength and the impact strength of the coating and metal, and the application range is wider.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, 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 or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
