The knife is a tool that we cannot have in daily life. However, the current knives are becoming more and more diverse. Ceramic knives are one of them and are also called "noble knives".With this reputation, it must be very different from other knives. What are the advantages and disadvantages of ceramic knife?What is the way to buy ceramic tools?Lets take a look today.
Ceramic knife structure performance
Traditional ceramic materials are generally taken from nature, such as the soil of Jingdezhen, which make various daily necessities through mixing, forming and roasting.And modern high -tech ceramics, also known as special ceramics, is artificially synthesized, such as silicon nitride powder, high purity.Made by modern powder metallurgical technology, the products made with high hardness and high temperature resistance.Materials can be divided into metal materials and non -metallic materials.Non -metallic materials are divided into inorganic materials and organic materials.The melting point of organic materials is low and the hardness is low.The melting point and hardness of metal materials are still not high.
Hard alloy performance is between metal and ceramics.Ceramic materials are mainly combined with ion bonds and covalent bonds. Its binding force is a relatively strong electrostatic gravity or shared electron pair between positive and negative ions, so high melting points, high hardness, good insulation, chemical stability, oxidation and oxidation properties are oxidizedEssenceThis is why ceramic materials can become cut tools.
The advantages and disadvantages of ceramic tools
High quality: ultra -high hardness, high temperature resistance, corrosion resistance, extremely sharp, not easy to wear, and never rust.Health: It is made of biomedical materials, which does not contain heavy metal elements such as nickel and chromium.In contact with the skin, it will not cause allergies.
Practical: Regardless of the treatment of some fruits and vegetables or meat, it can maintain its taxation without a sticky knife.
Packing: Ceramic knife packaging gifts, sets and other products are available, suitable for self -use or gift.Using lightweight: The proportion of ceramic materials is about 2/3 of the metal materials. It will not be as heavy as a metal knife.
Easy to clean: Use ceramic knife to cut onion and garlic and other irritating foods. Just rinse with water without leaving strange flavor.
The ceramic knife is made of sintering from oxide. The nature of its product raw materials determines that its hardness is 9, but it is relatively crispy.If the toughness is low, you cannot cut hard objects. If you fall into the heights, it is easy to collapse, lacks or breaks, so the ceramic knife cannot be cut, smashed, prysed, and tilted.
Ceramic knife selection
1. Look at the surface
The surface of high -quality ceramic knife is smooth, without flaws, fine lines, comfortable feel, high toughness, thick blade.The inferior ceramic knife has many surface stains, ash, cracks, pinhole, rough feel, and thin blade.
2. Look at the blade
The open blade line of high -quality ceramic knife is bright and fine, uniform.The open blade of the ceramic knife with low quality is thick, uneven and intermittent.Under the premise of ensuring safety, you can use your finger nails to gently blade the blade. The high -quality ceramic knife will not be broken, and inferior products will not bear a small pressure and crack.
3. Look at the details
The real ceramic knife pays great attention to details. It has been carefully polished and rounded in its back, knife tip, and knife.
4. Look at the material
The blade of the ceramic knife made of oxidative powder with a large diameter of powder, its blade will show obvious jagged shape.At the same time, the purity of oxidation in the high -quality ceramic knife is high, and the high purity powder makes the blade look transparent as jade, round and pure, and the inferior ceramic knife is mixed with aluminum powder because of oxidation powder.There are even black spots.
5. Test sharpness
Cut the ceramic knife on the paper. The high -quality ceramic knife is not only smooth and easy to cut, but also cuts the paper very finely. The inferior ceramic knife will have a clear sense of blocking, and the cut lines are rough.
