Embodiment Construction

[0011] 1 Prepare a small stove, manual fan, charcoal fire, crucible, borax, stainless steel cooling tank;

[0012] 2 According to the mass ratio, put 100 grams of four nine pure silver materials, 15 pure brass materials, and 13 grams of copper welding rod materials into the crucible at the same time, put the crucible in the middle of the small stove, heat the crucible with charcoal fire, after the charcoal fire burns Blow the fire with a hand-drawn fan, control the temperature of the crucible within 330°C, and slowly heat the crucible for a heating time of 20 minutes and a holding time of 50 minutes. There is no chemical layer on the surface of the brazing rod material;

[0013] 3 Then continue heating, pay attention to observe that the pure silver material, pure brass material, and copper welding rod material of the crucible are completely red. The three materials of copper welding rod material will melt slowly, and the molten liquid is mixed together. At this time, the tempe...

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 [0001] The invention relates to a processing method for silver jewelry auxiliary materials, in particular to a processing method for silver jewelry solder powder. Background technique [0002] As a cultural phenomenon, silver ornaments have been favored by many ethnic groups in history and have become one of the carriers of multicultural exchanges. The processing of silver ornaments of Miao nationality is all done by hand in family workshops; according to needs, silversmiths first smelt silver It is made into thin sheets, silver bars or silver wires, and exquisite patterns are produced by pressing, cutting, engraving, hugging and other processes, and then welded or woven into shapes. [0003] Soldering powder is generally used in the process of silver jewelry processing, but the existing soldering powder has poor fluidity, which is easy to damage the surface of the processed product, and some also produce black spots, which affects the quality of the product....
