With the development of the new technological revolution, it is required to continuously increase the productivity of cutting processing and reduce production costs. Especially the development of CNC machine tools, it is required to develop new types of tools with higher and more abrasion -resistant cuts than hard alloy knives.Therefore, ceramic knife has developed in such a background.So, what is the difference between ceramic kitchen knife and steel kitchen knife?Which ceramic knife and metal knife is better?Lets take a look today.
The difference between ceramic kitchen knife and steel kitchen knife
1. Traditional metal casting tools, because there are countless pores on its surface, there will be soup remaining in the pores when cooking ingredients, and the metal tools made of metal when cooking ingredients will have trace metal elements, forming odor or metal.Taste; and the density of the ceramic knife is quite high, so there is no pores on the surface and the ceramic material is developed, and there will be no odor or metal flavor.
2. In addition, the hardness of the ceramic knife is very high. The current manufacturing process has been greatly improved. The ceramic knife can withstand a certain impact, but it is still careful when used to prevent the sharp knife crack.Ceramics blade is also more than ten times that of steel knife, which is very sharp. Pay attention to safety when used to avoid childrens contact.Its abrasion resistance is 60 times that of metal knives, and it is almost never worn, eliminating the trouble of grinding the knife.
3. The chemical stability of ceramic materials is extremely strong, and it is resistant to acid and alkali and never rust.Do not have any chemical reactions with food, keep the food fresh and delicious.
4. The ceramic knife body has been sintered at a high temperature of 1700 ° C.It is not sticky during use, easy to clean and inhibit bacteria.
Which ceramic knife and metal knife are better
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 for ceramic tools.Regardless of the material. The nature. For example, the melting point, hardness, and conductivity mainly depend on the internal micro -structure.It depends on the combination and combination of internal mass points.
Organic materials are combined by weaker molecules, so the melting point is low and the hardness is small.Metal materials are combined by metal bonds. Its binding force is stronger than molecular bonds, but it is weaker than the common price bonds and ion bonds, so the melting point and hardness are still not high.Hard alloys use metals to connect hard to WC. Its 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.
Precautions for buying ceramic knife
The ceramic knife market is mixed with fish and dragons, and the true and false is difficult to argue, which has caused many consumers to be deceived and damaged. Then, it is particularly important to know how to identify the ceramic knife.The following is a support for everyone:
First, look at the surface: The surface of the high -quality ceramic knife is smooth, its light can be identified, 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.
Second, look at the blade: The open blade line of the high -quality ceramic knife is bright and fine, uniform.The open blade of the ceramic knife with low quality is thick, uneven and intermittent.
Third, look at the details: The real ceramic knife pays great attention to details. It has carefully polished and circular treatment at the back, the tip of the knife, and the head of the knife to effectively avoid the phenomenon of the injured hands.
Fourth, look at the material: The material of the ceramic knife is oxide powder.The high -quality ceramic knife is made of oxidized powder with a relatively large diameter of powder, so the blade will show obvious jagged shape.In addition, the purity of the high -quality ceramic knife is also relatively high. 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 oxide powder, and the blade light feels.Dull of dullness, even black spots.
V. Touch blade: Under the premise of ensuring safety, gently use your finger nails to gently cut the blade. The high -quality ceramic knife will not be broken, and the inferior ceramic knife will not bear a small pressure and cracks.
6. Test sharpness: Cut the ceramic knife on the paper. A good ceramic knife is not only smooth and easy to cut the cutting process, but also can cut the paper very well, but the bad ceramic knife will have a clear sense of blocking.More rough.
7. Anti -drop: If the ceramic knife falls from the kitchen platform accidentally, the high -quality ceramic knife will not break or collapse.High -quality ceramic knife raw materials are scarce, difficulty in mining, complicated blade processing technology, exquisite polishing technology, and quality inspection.Because its production cost is relatively high, the price is relatively expensive, but "a penny, one penny" is worthy of money, and it is trustworthy, so it has also received the enthusiastic attention of consumers.
