Embodiment 1

[0015] A processing method for bornite utensils, comprising the following steps: batching, casting, shaping, surface treatment, spotting and coloring, passivation and painting; the batching is to melt pure copper at 1200°C, and first add mica powder and talc powder, and then add calcium phosphate to melt to obtain copper liquid. Wherein, the added weight of the mica powder is 2% of the pure copper weight; the added weight of the talcum powder is 0.6% of the pure copper weight; the added weight of the calcium phosphate is 2% of the pure copper weight 0.2%. The streaks on the obtained born copper utensils are clear and uniform in color and regular in size.

[0016] Among them, the surface treatment is soaked in acetic acid for 20 minutes, then washed with deionized water, then soaked in a sodium bicarbonate solution with a mass percentage concentration of 3% for 18 minutes, then washed with deionized water, and then washed with a mass percentage concentration of 3%. % Soak in ...

Embodiment 2

[0018] A processing method for bornite utensils, comprising the following steps: batching, casting, shaping, surface treatment, spotting and coloring, passivation and painting; the batching is to melt pure copper at 1200°C, and first add mica powder and talc powder, and then add calcium phosphate to melt to obtain copper liquid. Wherein, the addition weight of described mica powder is 3% of described pure copper weight; The addition weight of described talcum powder is 0.8% of described pure copper weight; 0.3%. The streaks on the obtained born copper utensils are clear and uniform in color and regular in size.

[0019] Among them, the surface treatment is soaked in acetic acid for 30 minutes, then washed with deionized water, then soaked in a sodium bicarbonate solution with a mass percentage concentration of 5% for 20 minutes, then washed with deionized water, and then washed with a mass percentage concentration of 5%. % Soak in sodium sulfate solution for 10 minutes, wash...

Embodiment 3

[0021] A processing method for bornite utensils, comprising the following steps: batching, casting, shaping, surface treatment, spotting and coloring, passivation and painting; the batching is to melt pure copper at 1150°C, and first add mica powder and talc powder, and then add calcium phosphate to melt to obtain copper liquid. Wherein, the added weight of the mica powder is 1% of the pure copper weight; the added weight of the talcum powder is 0.5% of the pure copper weight; the added weight of the calcium phosphate is 1% of the pure copper weight 0.1%. The streaks on the obtained born copper utensils are clear and uniform in color and regular in size.

[0022] Among them, the surface treatment is soaked in acetic acid for 15 minutes, then washed with deionized water, then soaked in a sodium bicarbonate solution with a mass percentage concentration of 1% for 15 minutes, then washed with deionized water, and then washed with a mass percentage concentration of 1%. % Soak in ...

Abstract

The invention discloses a processing method of variegated copper ware. The method comprises the steps of burdening, casting, shaping, surface treatment, stretch mark coloring, passivation and japanning; and the burdening step is carried out by adding mica powder, talcum powder and calcium phosphate in the pure copper melting process and melting to obtain molten copper. The method makes stretch mark on the variegated copper ware have uniform color and same size and rule.

Description

technical field [0001] The invention relates to the field of bornite processing, in particular to a processing method of bornite utensils. Background technique [0002] Yunnan bornite is a unique traditional folk handicraft in Yunnan Province. It is named for its surface with golden and red stripes. Spot copper can be roughly divided into two types: "raw spot" and "cooked spot". It is a born copper handicraft made by adding a certain proportion of zinc, tin and other metals to molten pure copper, after casting, grinding, spotting and coloring. [0003] Affected by natural copper raw materials, the born copper utensils are basically "cooked spots". Due to factors such as craftsmanship, the spots on the surface of born copper utensils are irregular, different in size, and different in color depth, which affects the quality of born copper utensils. , making it difficult to increase the added value of born copper utensils. Contents of the invention [0004] The invention pr...
