Powder metallurgy composite antimicrobial stainless steel instrument and its preparation method

Abstract

The invention involves preparation method of powder metallurgy composite antibiotic non-corrodible steel equipment, it includes: shaping non-corrodible steel powder and preparing green compact; adding antibiotic metal powder into non-corrodible steel powder and preparing mixing powder; shaping the green compact and mixing powder in one time, coating the outside of green compact with mixing powder uniformly, then adglutinating, preparing the powder metallurgy composite antibiotic non-corrodible steel equipment after thermal treatment, the equipment includes the integral body of knives, scissors, clamps, forks, bowls, pans, spoons, tweezers, cups or its combinations. The antibiotic metal ion in the surface antibiotic layer can make the equipment play antibiotic role in the utilization process.

Description

Technical field

[0001] The invention relates to stainless steel appliances for food and its processing, daily life, and medical treatment, in particular to powder metallurgy composite antibacterial stainless steel appliances and a preparation method thereof. Background technique

[0002] Harmful microorganisms in the natural world seriously threaten human health, and millions of people all over the world die from bacterial infections every year. The way humans are infected with bacteria is mainly through imported food and contact with bacteria. Kitchenware, daily utensils, especially medical appliances that directly contact food often become the source of microbial growth and reproduction. Food industry, medical and health industries, and general households There is an increasing demand for kitchenware and medical appliance products with excellent bacteria and antibacterial properties.

[0003] Antibacterial materials refer to materials that have the function of killing or inhibi...
