How is a ceramic knife made and how is a ceramic knife sharpened?

1. Load water, raw material powder and grinding balls into a mixer and stir well.

2. Through filtration, the diameter is consistent, and the size of nano-sized raw material particles cannot exceed 1 micron.

3. Spray, dry, dehydrate and granulate to make granular powder.

4. Fill the made powder with a knife-shaped mold.

5. Through the press, the pressure of about 12,900 pounds per square centimeter is applied to the powder in the mold to fix the powder into a knife shape.

6. Put the powder fixed into a knife shape into the kiln, and accurately control the temperature for sintering.

7. During the whole sintering process, the blade will be reduced to 75% to 50%, and the shrinkage ratio will be different for different raw materials, so the shrinkage ratio must be taken into account when designing the ceramic knife mold.

8. After the kiln is discharged, the surface of the blade is processed and the blade is cut through diamond grinding wheel and other equipment.

9. Install the handle of the knife, and a healthy and sharp green ceramic knife will be made.

The material is prepared first, powdered, and made by high pressure into the abrasive, sintered at more than 1,000 degrees, and ground after being baked. What I want to say is that there are not many factories that really produce in China, and too many are resold and re-sold, including the daily knives sold in Japan, most of which come from the mainland.

For holiday gifts, many people are increasingly choosing fashionable and practical ceramic knives as gifts.

Yangjiang Yinying Ceramic Knife They produce is the largest enterprise in the country.

Ceramic knives are very hard, so they can only be sharpened with diamonds. This grinding process is time-consuming, usually at least 20 minutes or more by hand, and without sharpening technology, it is very likely to change the previous edge angle. Therefore, the choice of electric sharpener made of diamond material is used for sharpening ceramic knives.

The ceramic knife is polished by hand, and each side is uniformly curved inward, which can maximize the strength of the ceramic knife and ensure the smoothness of cutting. The hand-sharpened blade and blade surface are uniform and consistent, with a high finish and easy to clean.

Every family has to cook every day, kitchen knives are very important in daily life, and then pchouse will take you to understand what a ceramic knife is.

Ceramic knives are mostly machined from a nanomaterial called zirconia. Zirconia + alumina powder is pressed into a knife blank with a heavy pressure of 300 tons and a mold, sintered at 2000 degrees Celsius, and then polished with diamond and then equipped with a handle to make a finished ceramic knife.

The ceramic blade is a new type of blade made of high-tech nanotechnology, and the sharpness is more than ten times that of the steel knife, so the ceramic knife has the characteristics of high hardness, high density, high temperature resistance, anti-magnetization, and anti-oxidation.

The ceramic knife is developed using high pressure of precision ceramics, so it is called ceramic knife. As a product of modern high technology, ceramic knives have incomparable advantages over traditional metal knives; The use of high-tech nano zirconia as raw materials, so the ceramic knife is also called "zirconium gem knife", its elegance and preciousness can be seen.

What are kitchen knives used for? Technology has brought about a new product - ceramic knife. The ceramic knife fully embodies the green environmental protection concept of the new century and new materials, and the new fashion of environmental protection and the new life are the high-quality life of human beings pursuing environmental protection and health.

So what is a ceramic knife? How about ceramic knives?

The ceramic knife is developed using high pressure of precision ceramics, so it is called ceramic knife.

Ceramic knives are made of high-purity ultra-fine zirconia as raw materials, manufactured by spray granulation, isostatic pressure forming, precision machining and other processes, with high hardness, strong corrosion resistance, good chemical stability, high wear resistance and other characteristics, beautiful and exquisite appearance, sharp edge, is a knife that will never wear out and never corrode in the true sense.

Characteristics of ceramic knives::

High hardness, high wear resistance. It is made of high-tech high-temperature ceramics used in aerospace, and its hardness is only slightly lower than that of diamond.

The blade is so sharp that it doesn't need to be sharpened and is extremely durable.

Anti-corrosion, no iron smell, never rust, easy to clean. Does not bring odor to food.

Non-toxic, hygienic and environmentally friendly. The surface density is high, which is not easy to contaminate food juices, reducing the chance of bacterial growth. The ceramic knife has a super antibacterial function, which is very suitable for cutting food that can be eaten directly.

It is the best knife to care for the healthy growth of infants and young children. The green knife retains the original color and flavor of the food. The chemical properties of the material are stable, healthy and environmentally friendly.

It can resist the corrosion of various acids and organic compounds, and does not react with food. Ideal for cutting sashimi, fruits, vegetables, boneless meats and cooked foods.

The color is round, white, and has the texture of jade, adding noble enjoyment.

Ceramic knives should be used with wood, bamboo and other cutting boards. It is best used with an antibacterial cutting board, but should be avoided on a stone cutting board. Do not expose to high temperatures. Do not use high-temperature sterilization cupboards for sterilization (handles are not resistant to high temperatures).

Due to the special properties of ceramic knives, the hardness is second only to diamond, so do not use them as chopping knives when handling food, and should avoid heavy falls or external force impacts, so as to prevent the blade from falling, so as not to cause the ceramic blade to be missing or broken. Ceramic knives can be used for cutting, cutting, etc., but not for chopping, smashing, prying, and picking.

It is especially not suitable for chopping bones and cutting frozen foods. After the knives are used, they can be cleaned with water and detergent, and after cleaning, they can be placed on the knife holder or stored in the knife box.

The blade itself is sharp and easy to cut hands, so special care should be taken when storing it, and care should be taken not to reach children to avoid misuse.

As a product of modern high technology, ceramic knives have incomparable advantages over traditional metal knives; The use of high-tech nano zirconia as raw materials, so the ceramic knife is also called "zirconium gem knife", its elegance and preciousness can be seen in general.

It can be sharpened with a knife sharpener. The following introduces the specific operation method, first prepare the materials: ceramic knife, knife sharpener Keiho.

2. After putting the knife sharpener, grab the knife handle with one hand and press the tip of the knife with the other hand, Yu Youbu then put the ceramic knife on the knife sharpener.

3. Push from the bottom to the top, and repeat this action repeatedly until the knife is sharpened.
