"How are these knives all white, is it a film attached? Is it easy to use?" Recently, in the face of a demonstration of a staff member at a tool sales counter, Hu Aunt, who lives in Fengtai District, Beijing, could not help but ask such questions. . "The metal knives have always been used, and this white ceramic knives have never been used."
For some consumers who are used to traditional metal knives, this white ceramic knife is really a new thing. In recent years, with the improvement of people's living standards and the trend of low-carbon and environmental protection, the tool market has also ushered in innovation and reform. Ceramic knives are such a new material of green products.
“The reason why it is called ceramic knives is because it is made of high-precision ceramics. Most of the ceramic knives currently on the market are made of a nano-material zirconia.†A staff member in front of the tool exhibition platform said . "Using zirconia powder at a high temperature of 2000 ° C with 300 tons of heavy pressure and pressing the mold to form a blank, which is then polished with diamond and fitted with a shank. The ceramic knives have high hardness, high density, high temperature resistance, Anti-magnetization, anti-oxidation and other characteristics, so this knife is also called 'noble knife'."
Listening to the introduction of the staff, the reporter carefully compared the ceramic knives, because it is the texture of the ceramic material, and all of them are polished by hand, so each side of the surface is evenly curved inward, thus maximally guaranteeing the knives. Strength while ensuring smoothness during cutting. The blade and the blade face are uniform, the finish is high, and it is easy to clean. Moreover, due to the use of high-tech nano-zirconia as raw material, the ceramic tool is not afraid of strong acid and alkali, and will not corrode after long-term use, which avoids the metal cutter when cutting fruits and vegetables. Oxidation that can occur.
"Let's take a look. The knife used to cut the onion will make you burst into tears. You can use a ceramic knife to cut it without spicy eyes. When you cut vegetables and fruits, you won't leave a metallic smell. The surface of cut potatoes and apples is also Not easy to be oxidized, don't believe to try it yourself." The staff sipped while demonstrating and attracted the attention of many consumers.
It is understood that the emergence of new ceramic knives is the first time that human beings have revolutionized mechanical cutting by using ceramic materials. As early as the beginning of the last century, Germany and the United Kingdom have begun to seek to replace traditional steel tools with ceramic tools. Ceramic materials have become a new generation of tool materials due to their high hardness and high temperature resistance. However, ceramics are also limited by the well-known brittleness. Therefore, how to overcome the brittleness of ceramic tool materials and improve its toughness has become a ceramic tool for nearly a hundred years. The main topic of research. The range of applications for ceramics is also growing.
According to industry insiders, so far, the materials used as ceramic knives have been alumina-metal ceramics, alumina-carbide ceramics, alumina-carbide cermets, alumina-nitride cermets and the latest research success. Boron nitride ceramics. Worldwide, German ceramic tools have not only been used in ordinary machine tools, but have also been used as an efficient, stable and reliable tool for CNC machine tools and automated production lines. Japanese ceramic blades are internationally advanced in terms of product type, output and quality. The United States has been a world leader in the development of oxide-carbide-nitride ceramic tools. China's ceramic tool development and application has also achieved many major achievements.
Ceramic knives are one of the most popular green products in the world. Nowadays, after several years of market development, ceramic knives have begun to enter the homes of ordinary people. The reporter found through investigation that there are many ceramic knives on the Internet, not only in various styles, but also in fruit knives, kitchen knives, planing knives, and suits. The handle also has 3 large materials to choose from, plastic handles, wooden handles and ceramic handles. The most widely used is the plastic handle, followed by the wooden handle, the wooden handle is mostly used in the high-grade ceramic knife, and the ceramic handle is easy to break.
"The price of one point is worth the price." At present, the ceramic knife market is mixed, and it is difficult to distinguish between true and false, which has caused many consumers to be deceived. Therefore, it is especially important to know how to distinguish ceramic knives." Running a brand in Tmall Mall Miss Wu of ceramic knives said. First, look at the surface: the surface of the high-quality ceramic knives is smooth, its light can be seen, no flaws, fine lines, comfortable hand, high toughness and thick blades. Inferior ceramic knives have many stains on the surface, such as gray spots, cracks, pinholes, rough hand and thin blades. Second, we must look at the blade: the edge of the high-quality ceramic knife is bright and uniform. The ceramic blade with low quality is thicker and wider, uneven and intermittent. Third, look at the material: the material of the ceramic knife is zirconia powder. The high-quality ceramic knives are made of zirconia powder with a relatively large diameter, so that the blade will have a sharp zigzag shape. Moreover, the quality of the high-quality ceramic knives is also relatively high. The high-purity powder makes the blade look like jade, round and pure, while the inferior ceramic knives incorporate aluminum powder into the zirconia powder. Dumb, even black spots. Four must touch the blade: Under the premise of ensuring safety, the fingernail is lightly rubbed by the fingernail, the high-quality ceramic knife will not be broken, and the inferior ceramic knife will not bear the small pressure and crack.
