A kind of production process of tin clad pot

Abstract

The invention relates to a production technology of a tin-coated pot. The technology comprises steps as follows: (1) tin sheets are thinned, and required patterns are engraved; (2) the surface of a sand-fired pot is polished clean, and the opening and the bottom edge of the sand-fired pot are coated with tin sheets; (3) the tin sheets processed in Step (1) are attached to the surface of the sand-fired pot, and a rubber hammer is used for lightly knocking the tin sheets to enable the tin sheets to be closely attached to the sand-fired pot; (4) patterns of the tin sheets on the surface of the sand-fired pot as well as the tin sheets coating the opening and the bottom are welded, and a finished product is obtained; during welding, a mixture with the weight ratio of a tin alloy to sulfur being (3-7):1 is used for welding, the welding temperature is in a range of 185-200 DEG C, and the tin alloy is a tin-copper alloy with the weight ratio of tin to copper being (6-8):1. The production technology of the tin-coated pot is simple, the defective sand-fired pot can be processed and produced into the exquisite tin-coated pot, so that the defective sand-fired pot is utilized, the processing cost is saved, the bonding effect of the processed tin sheets and the pot is good, the pot does not crack, and the ornamental value of the sand-fired pot is increased.

Description

technical field [0001] The invention belongs to the field of pot processing, and in particular relates to a production process of tin-clad pots. Background technique [0002] Zisha teapots are hand-made clay crafts with Chinese Han characteristics, and now they are also mass-produced by machines. The raw material is purple sand mud, and its origin is Yixing, Jiangsu. Zisha teapots are popular in the auction market, and they are "antiques" with collection value. It is often hard to find a pot of works by famous masters. As the saying goes, "there is nothing to buy in the world, but Yixing Zisha is the most important thing." [0003] Zisha teapots have long been admired as ideal tea injectors. Its excellent practical functions have been recorded in the documents of Ming and Qing dynasties. People in the Ming and Qing dynasties believed that the reason why teapots "retire silver tin and Fujian and Henan porcelain, and prefer pottery" is that the purple sand pot can emit ...

Problems solved by technology

[0004] However, the production process of purple clay teapots is cumbersome, the production process requires high requirements, and there are many defective products. Most of the defective products are surface defects of the teapot. Direct discarding will cause serious waste, but it is not easy to sell.
