Abstract

The invention relates to the machining technical field of silver products and particularly relates to a method for manufacturing the primary-color silver, which comprises the steps of silver material molding and sintering. After the sintering step, the method also comprises the steps of silverware pickling and fine-grinding treatment. The fine-grinding treatment is conducted by means of red sand cotton. Through the fine-grinding treatment, textures are ground on the surfaces of silver products, so that the primary color of the silver products can be presented. The primary color of silver products obtained through the above method can be well recovered, so that the silver products are beautiful, elegant and good in collection value. Meanwhile, the silver products obtained through the method are free of any chemical residue, healthy and environment-friendly, thus being more beneficial to human health. During usage, the silver products are better in health-preserving value. At the same time, the method emphasizes the pickling step before the fine-grinding treatment. In this way, primary-color silver products are better in color and luster.

Description

technical field [0001] The invention relates to the technical field of silver product processing, in particular to a method for producing primary-color silver. Background technique [0002] Before BC, the ancients knew that silver has the functions of accelerating wound healing, preventing infection, purifying water quality and preserving freshness. Silver has an excellent sterilizing effect. Common antibiotics can only act on 6 kinds of germs on average, but silver can eliminate 650 kinds of germs.
