Antibacterial antioxidative ceramic knife

Abstract

The invention relates to an antibacterial antioxidative ceramic knife and belongs to the technical field of production of functional ceramic knives. The antibacterial antioxidative ceramic knife comprises a ceramic knife body and a plastic handle. The antibacterial antioxidative ceramic knife is characterized in that a special ceramic with higher strength is adopted as the knife body, so that mechanical strength, thermal stability and dielectric strength of the ceramic knife are enhanced, corrosion caused by liquid and gas can be prevented, and the ceramic knife is durable; a negative ion layer is arranged on the outer surface of the ceramic knife body, an antibacterial effect can be achieved, and a common ceramic knife is upgraded into a functional high-grade kitchen utensil.

Description

technical field [0001] The invention relates to a ceramic knife, in particular to an antibacterial and anti-oxidation ceramic knife, belonging to the technical field of functional ceramic knife production. Background technique [0002] Ceramic knives are developed using precision ceramics under high pressure, so they are called ceramic knives. Ceramic knives are known as "noble knives". As a product of modern high technology, they have advantages that traditional metal knives cannot match; high-tech nano-zirconia is used as raw material, so ceramic knives are also called "zirconium gem knives". It can be seen. [0003] As early as 1913, ceramic materials were tried to be used as cutting tools, but they were not widely used. It was not until the 1950s that ceramic knife materials were gradually developed. Ceramic knives have many unique characteristics, such as high heat resistance, high hardness and wear resistance, good high-temperature mechanical properties, etc., a...

Problems solved by technology

However, due to the well-known brittleness of ceramics, the scope of use of ceramic knives is limited, so how to overcome the brittleness of ceramic knife materials, improve their mechanical strength, thermal stability, dielectric strength, and prevent liquid and gas corrosion, Making it durable has become the main topic of research on ceramic knives for nearly a hundred years

[0005] At present, the patents on ceramic knives only focus on the fact that the knives are made of ceramics. 201220549610.3 discloses a preparation process for ceramic knife strips. The steel strips are bonded to the ceramic knife strips so that the steel strips become the main body of the load, which greatly avoids ceramic knife strips. The fracture caused by poor toughness prolongs the life of the ceramic blade and reduces the cost, but there is a lack of research on the handle

201020598567.0 discloses a ceramic knife, including: a ceramic knife body and a metal knife handle, the connection between the two is difficult to be perfectly matched, and the knife body often falls out of the knife handle, which is inconvenient to use

[0006] In addition, when cutting fruits with metal knives, it is common for fruits to be easily oxidized and browned when exposed to the air, resulting in the loss of nutrients and the appearance of fruits.
