Teach you how to choose good ceramic knife eyes are open wide: a close look at the surface finish of ceramic knives, the side without blemish gray point, the tensile strength test, there are the first part of the impurity tainted cracks began to appear. Carefully touch the blade: high-quality ceramic knife lines should be fine, not rough, feels smooth blade, toughness, best quality glossy ceramic knife even when the mirror can smooth and curved blade at the blade through a special process, sharp higher degree, can shave beard and hair. Touch handle: the market lower inferior product ceramic knife handle is not bone china. It uses a secondary hardening magnesia porcelain, bone china handle to reduce the relative cost a lot. If you take together contrast, we can see the second strengthen porcelain finish and brightness, ceramic knives can wear it, and the softness of color are greatly reduced. And the process is easy to handle and use the blade separation, life will be greatly shortened. Ceramic knife handle carefully designed according to human engineering, not only taking into account the movement and strength of the cooking time, the ceramic knife how to sell, but also to achieve the curve shape and stability of the handle, which makes the operation center of gravity stable, ceramic knives, cut food perfect ease. Require manufacturers to provide zirconia particles of diameter. Diameter zirconia particles is the most important indicator of a factory core technology level, the smaller the diameter of the particles out of the blade density forging more degrees, higher hardness, and we can observe through a microscope to compare the use of large diameter particles appear blade a very clear jagged. The average <0.6, just 1/60 of the size of our ceramic knife diameter product particles inferior products on the market, which is the difference between heaven and earth! How to check the blade zirconia powder purity. High purity powder transparent jade, ceramic knife price, but usually some inferior ceramic knife is a mixture of aluminum powder, not only of transparency, color gray, and the blade easy to change color, brittle. Currently alumina ceramic cutting tool steel, cast iron, alloy steel and stainless steel and other materials commonly used carbide-based cemented carbide (WC-Co, WC-TiC-Co). For some special materials also used the highest hardness and diamond cubic boron nitride (CBN), but their intensity lower than the cemented carbide and diamond cutting tools against iron and steel materials, since the diamond element and the carbonaceous easy to iron the reaction of iron carbide, leaving the diamond loss, but the diamond tool for processing aluminum-silicon alloy has unique advantages. The CBN many iron-based material, etc. are not react machining chilled cast iron, Stellite, Hastelloy, etc. have good performance.
