Abstract
The invention discloses a processing method for welding powder for silver ornaments. The processing method comprises the operation steps of placing 10 parts of pure silver, 1.5 parts of pure brass and 1.3 parts of copper welding rods into a crucible for being heated according to the mass proportion, wherein the heating temperature ranges from 300 DEG C to 360 DEG C; continuously heating the raw materials until the temperature of the crucible reaches 1200-1280 DEG C and the raw materials in the crucible are molten, then stirring the molten materials, lowering the temperature of the crucible to 800-860 DEG C and adding 1-2 parts of borax into the crucible according to the mass proportion; continuously heating the crucible until the temperature of the crucible reaches 1000-1020 DEG C, then pouring the molten materials in the crucible into a cooling tank for being cooled, taking out the molten materials, soaking the molten materials into phosphoric acid solutions with the mass percent concentration being 15-25% for 2-5 minutes, then taking out the molten materials, cleaning the molten materials through clean water, grinding the molten materials through a fine sand belt grinding wheel, and finally obtaining the welding powder for the silver ornaments after grinding. The melting point of the welding powder processed through the method is low, the mobility is good, the product surfaces are protected against damage, black patches are avoided, and welded products are attractive and clear.
Description
Technical field
The present invention relates to silver jeweleries adjuvant processing method, especially a kind of silver jeweleries welding powder processing method.
Background technology
Silver jeweleries in history once by many national favors, becomes one of carrier of multiculture exchange as a kind of cultural phenomenon, and the processing of Miao ethnic group's silver jeweleries, is complete with the manual operations in family workshop entirely；As required, silversmith first laminates the silver of melting, Rhizoma Humatae Tyermanni or filamentary silver, utilize pressure, few, carve, the technique such as hug, make exquisite grain pattern, then welding or knitting forming again.
Generally will using welding powder in the silver jeweleries course of processing, and existing welding powder exists poor fluidity, easily hurts the surface of converted products, some also produces black patches, have impact on product quality.
Summary of the invention
For the deficiencies in the prior art part, it is desirable to provide a kind of silver jeweleries welding powder processing method, to guarantee good fluidity, do not hinder work surface, do not play black patches.
For solving above-mentioned technical problem, a kind of silver jeweleries welding powder processing method that the present invention adopts, including following operating procedure:
10 parts of fine silver material, 1.5 parts of simple brass material, brazing billot 1.3 parts are put into and are heated in crucible by quality proportioning by 1, and heating-up temperature is 300 360 DEG C, 20 30 minutes heat time heating times, temperature retention time 30 60 minutes；
2 then proceed to heating, make crucible temperature reach 1,200 1280 DEG C, 20 35 minutes heat time heating times, are incubated 15 30 minutes, and fine silver material, simple brass material, brazing billot melt, and then stir liquation, make liquation Homogeneous phase mixing；
Crucible temperature is slowly decreased to 800-860 DEG C by 3, temperature fall time 15 20 minutes, is then incubated, insulation insulation 15 30 minutes, pulls the slag in crucible out, adds 1-2 part Borax by quality proportioning in crucible；
4 reheatings make crucible temperature reach 1,000 1020 DEG C, heat up 15 20 minutes heat time heating times, it is incubated 5 10 minutes, then crucible liquation is poured into cooling bath cooling, cooling bath temperature is taken out after dropping to room temperature and is taken out after soaking 25 minutes with the phosphoric acid solution that mass percent concentration is 15 25%, clean by clean water again, to polish with fine sand band emery wheel, the powder ground is exactly silver jeweleries welding powder.
The welding powder fusing point of this method processing is fast, and good fluidity is not hindered works face, do not played black patches, and the works welded are exquisite clear.
Detailed description of the invention
1 gets out little cooking stove, Hand driving fan, charcoal fire, crucible, Borax, rustless steel cooling bath；
2 press quality proportioning, put in crucible with four nine fine silver material of 100 grams, 15 simple brass material, brazing billot 13 grams simultaneously, crucible is placed in the middle of little cooking stove, using charcoal fire heating crucible, blow the fire with punka after charcoal fire burning, crucible temperature controls in 330 DEG C, crucible is made slowly to heat, 20 minutes heat time heating times, temperature retention time 50 minutes, described brazing billot appearance does not have medicine layer；
3 then proceed to heating, notice that the observation fine silver material of crucible, simple brass material, brazing billot burn and are popular in, dry with fan after burning is popular in, when reaching 1250 DEG C of crucible, fine silver material, simple brass material and three kinds of material of brazing billot will slowly melt, and liquation mixes, and at this moment temperature can not reduce, it is always maintained at 1220 DEG C and burns refining, until the whole fusing fluid of material of crucible, stir with in a little batten crucible cup, make liquation Homogeneous phase mixing, about 30 minutes heat time heating time, it is incubated 15 minutes；
4 crucible temperatures are slowly decreased to 820 DEG C of insulations, temperature fall time is about 17 minutes, insulation insulation 15 minutes, it is noted that the surrounding of crucible piles charcoal fire could keep temperature during insulation, pull the slag in crucible out with a little batten simultaneously, in crucible, add 10 grams of Boraxs by quality proportioning, make liquation become bright, clean；
5 reheatings make crucible temperature reach 1010 DEG C, heat about 17 minutes, it is incubated 5 minutes, then crucible liquation is poured into the cooling of rustless steel cooling bath, cooling bath temperature is taken out after dropping to room temperature after soaking 2 minutes with the phosphoric acid solution that mass percent concentration is 15% and is taken out, clean by clean water again, to polish with fine sand band emery wheel, the powder ground is exactly weld welding powder for silver jeweleries.
