Abstract
The invention discloses a pretreatment process before silver plating. The pretreatment process before silver plating comprises the following process steps: polishing, cleaning, deoiling, activation drying and finishing; and drying a blank, polishing the surface of the blank by sandpaper, then cleaning the blank by countercurrent clear water and completely drying the blank for later use. By virtue of the mode, with the adoption of the pretreatment process before silver plating, oxide on the surface of the blank is completely removed, and the surface of the blank is smooth and level, so that the combination of the surface of a part after silver plating and a silver plating layer is facilitated, the phenomena of peeling and bubbling difficultly occur, and the quality and the durability of the surface are improved.
Description
Technical field
The present invention relates to the silver-plated processing technology field of part, particularly relate to a kind of silver-plated front pretreatment technology.
Background technology
Silver-plated is utilize the good electric conductivity of argent, erosion resistance and reflective function, silver is plated in the technology of metal or other solid material surfaces.Silvering is applied to decorative article field the earliest, provides the outward appearance of silver elegance, and the easy polishing of silvering, has good heat conduction, conduction and welding property, extensive at industrial aspect Application comparison at present.
Piece surface due to bronze material is difficult to process, and its silver-plated rear problem easily occurring peeling or foaming, the bonding force of coating and part is poor, needs to carry out pre-treatment.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of silver-plated front pretreatment technology, removes dirt and the oil stain on bronze parts surface, improves the bonding force after electroplate.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of silver-plated front pretreatment technology, comprise following processing step:
A, polishing: polish to the blank of bronze parts, remove protruding particle and the sand holes on surface, and be placed in the clear water of adverse current and clean;
B, cleaning: the blank after polishing is put into Ultrasonic Cleaners and cleaned;
C, to deoil: in pond, add removers, be heated to 50 degree and be incubated, then blank is poured in pond, basin bottom passes into bubble, pull out after cleaning 3min and clean in the clear water of adverse current;
D, activation drying: blank is flooded in dilute hydrochloric acid solution after dilution, pulls out after 15 seconds and clean in the clear water of adverse current;
E, bright and clean: the rubber polishing carrying out surface after blank drying, in the clear water of adverse current, then carrying out cleaning, also finish-drying is for subsequent use.
In a preferred embodiment of the present invention, be provided with ultrasonic cleaning agent in described Ultrasonic Cleaners, the set of frequency of Ultrasonic Cleaners is 26KHz ~ 28KHz.
In a preferred embodiment of the present invention, the concentration of described dilute hydrochloric acid solution is 25%.
The invention has the beneficial effects as follows: the silver-plated front pretreatment technology of the one that the present invention points out, the blank surface oxide removal obtained is clean, smooth, is conducive to the combination of silver-plated rear piece surface and silvered film, not easily produce peeling or foaming phenomena, improve surface quality and wearing quality.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of silver-plated front pretreatment technology, comprises following processing step:
A, polishing: polish to the blank of bronze parts, remove protruding particle and the sand holes on surface, and be placed in the clear water of adverse current and clean, and rinses out foreign material and the particulate matter on surface;
B, cleaning: the blank after polishing is put into Ultrasonic Cleaners and cleaned, make the dirt in blank surface and gap be disperseed and peel off, and cleans more thorough;
C, to deoil: in pond, add removers, be heated to 50 degree to be incubated, then blank is poured in pond, basin bottom passes into bubble, pull out after cleaning 3min and clean in the clear water of adverse current, bubble accelerates the speed of cleaning, and removers can be sent in the gap of blank and clean;
D, activation drying: blank is flooded in dilute hydrochloric acid solution after dilution, pulls out and clean in the clear water of adverse current after 15 seconds, make the oxide compound of blank surface produce and loosen;
E, bright and clean: the rubber polishing carrying out surface after blank drying, remove the oxide compound epidermis on blank, in the clear water of adverse current, then carrying out cleaning, also finish-drying is for subsequent use.
Described silver-plated front pretreatment technology have employed Ultrasonic Cleaners especially, is provided with ultrasonic cleaning agent in described Ultrasonic Cleaners, improves the effect to various dirt matting, and the set of frequency of Ultrasonic Cleaners is 26KHz ~ 28KHz.
Further, the concentration of described dilute hydrochloric acid solution is 25%, the surface of activation blank, oxide compound is loosened and even comes off.
In sum, the silver-plated front pretreatment technology of the one that the present invention points out, the inclusion particles of removing bronze parts blank surface, greasy dirt and oxide compound, prepare for silver-plated, improve the bonding force of silvered film and blank, not easily peeling or come off.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
