Zirconia ceramic knife
At present, most ceramic knives on the market are made of a nanometer material "zirconia". Zirconia+alumina powder is pressed into a 300-ton tool blank, which is matched with a mold, sintered at 2000 degrees Celsius, polished with diamond and matched with a handle to make a finished ceramic knife. Ceramic blade is a new type of blade made of high-tech nanotechnology, and its sharpness is ten times that of steel blade, so ceramic blade has the characteristics of high hardness, high density, high temperature resistance, magnetization resistance and oxidation resistance.
Ceramic knives are made of precision ceramics under high pressure, so they are called ceramic knives. Ceramic knives are called "noble knives". As the product of modern high technology, they have incomparable advantages over traditional metal tools. High-tech nano-zirconia is used as raw material, so the ceramic knife is also called "zirconium gem knife", and its elegance and preciousness can be seen.
Which brand of zirconia ceramic knife is good?
1、? Germany Shuanglian is famous for its rigor. In any field, Germany has done very well. Shuanglian is a famous kitchen brand in Germany. 173 1 year, the symbol of Zyrnior was born in solingen, a small town on the Rhine. It is one of the oldest symbols in human history and has become an immortal legend. With unusual steel formula and unique ice forging technology, it has become a symbol of ultimate life and perfection.
2、? Sandvik and sandvik are Swedish brands founded in 1862, and they are the world's leading tool brands. The products changed from industry are made of cemented carbide, high speed steel, diamond and other hard materials such as special ceramics. Sandvik's cutting tools are the best in the world market.
Mitsubishi's brand originated in Japan. Mitsubishi Tools is one of the products of Mitsubishi Group. It enjoys a high reputation in the whole tool industry, has the most advanced technology, innovates constantly, grasps the market dynamics quickly, and can provide products that customers need.
use
From aerospace and other high-tech fields to industrial ceramic tools, they have been widely used in civil applications in recent two years. Ceramic knives fully embody the concept of green environmental protection and new materials in the new century, are environmentally friendly and fashionable, and feel a new life, which is a high-quality life for human beings to pursue environmental protection and health; Lightweight, beautiful, fine and polished appearance adds a blend of nobility and modernity, and it has become a trend for ceramic knives to replace metal knives.
superiority
Zirconia ceramic knife has the advantages of wear resistance, high density, high hardness, no capillary holes, no filth, no rust in non-metal casting, no residual metal smell in cutting food, light and sharp, easy to take, easy to cut and easy to clean. , and has many irreplaceable characteristics of metal tools.
The Mohs hardness of zirconia ceramic knives is 9, which is second only to the hardest substance in the world ── diamond (Mohs hardness is 10), so as long as it does not fall to the ground during use, there is no need to sharpen the knife under normal use. For safety reasons, manufacturers usually mix metal powder into the blade so that metal detectors can detect ceramic knives.
However, zirconia ceramic knives are not suitable for cooking foods that need to be chopped, so other hard food materials such as vegetables, fruit pulp, sashimi and so on. Not suitable for cooking with ceramic knives.
Non-rigid foods such as bamboo shoots (excluding shells), meat, seafood and shellfish without shells can be used. Traditional metal casting tools have numerous small holes on the surface, so they are used when cooking ingredients. There is soup in the capillary, and the metal knife will have trace metal elements when cooking ingredients, forming an odor or metallic taste; The density of zirconia ceramic knives is quite high, so there are no pores on the surface, and the ceramic materials are developed, so there will be no peculiar smell and metallic taste.
In addition, the hardness of zirconia ceramic knife is very high, and the manufacturing process has also been greatly improved. Zirconia ceramic knife can bear certain impact, but it should be used with extra care to prevent the sharp and thin blade from cracking. The sharpness of ceramic knives is ten times that of steel knives, which is very sharp. Pay attention to safety when using, and avoid children's contact.
To sum up, zirconia ceramic knives have various characteristics, such as wear resistance, high hardness and high density, which are ten times sharper than ordinary steel knives. They are called "noble knives", which are symbols of elegance and preciousness, and are loved and bought by consumers. Everyone should fully understand all kinds of information about zirconia ceramic knives before buying, so as to choose zirconia ceramic knives that suit themselves and meet their needs. It is said that choosing what suits you can improve the happiness of yourself and your family. The above is all kinds of information about zirconia ceramic knives for everyone to share.
