Pure silver clad alloy chopsticks and preparation method thereof

Abstract

The invention relates to a hollow light chopstick made of pure silver clad alloy and a preparation method of the chopstick. A chopstick body comprises a stainless steel parent layer and a silver clad layer, the surface of the stainless steel parent layer is covered with the silver clad layer, the stainless steel parent layer is of a hollow tubular structure, the head of the chopstick body is in a cuboid shape, the tail of the chopstick body is in a cylinder shape, the head of the chopstick body is held by a hand, and the tail of the chopstick body is used for clamping food. The stainless steel parent layer is made of a stainless steel pipe through steel pipe fixed-length cutting, large-end hole shrinkage, small-end hole shrinkage, two-end sealing, punch forming and overall polishing, and then the silver metal layer with the purity larger than or equal to S990 is subjected to drawing, calendaring and sealing overall covering, and thus, the manufactured chopstick body has the advantages of being high in hardness, resistant to high temperature, not prone to corrosion, capable of achieving sterilization and disinfection, light, easy to use and the like; meanwhile, the manufacturing cost and the use threshold of the silver chopstick are reduced, and a brand-new healthy diet habit is favorably popularized.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to hollow light chopsticks clad with pure silver and an alloy and a preparation method thereof.

Problems solved by technology

[0003] Chopsticks made of natural plant materials such as bamboo and wood generally need to be bleached or decontaminated with chemical substances in the production process. Such chemical substances will adhere to the chopsticks, and eventually the residual chemical substances will be with the food during use. If it enters the human body, it will pose a potential threat to the health of the user; and this type of chopsticks is light and soft, not hard enough, and is easy to bend and deform if used improperly. Bamboo chopsticks cannot enter the microwave oven and other kitchen appliances. Moldy and spoiled

[0004] Chopsticks made of industrial synthetic products such as plastics are not resistant to high temperatures, and are easily deformed and melted after being heated, thereby producing substances harmful to the human body

[0005] Chopsticks made of alloy metal are currently widely circulated alloy metal chopsticks in the market, mainly stainless steel chopsticks. The material of this kind of chopsticks is usually 201 stainless steel, which is far more corrosive than household stainless steel. If it is used for a long time, it may cause the body to inhale Excessive heavy metals will cause certain harm to health; and solid alloy metal chopsticks are heavy, which will test the user's wrist strength and poor practicability
