How can the watermark on the zirconia ceramic knife be wiped clean

For many friends who like to cook, there will be a little annoyance, that is, the ceramic knife set is easy to get a layer of stains, how to easily clean these ceramic knife sets? Generally, many people will use rough cleaning tools such as steel wool balls (cleaning balls) or loofahs to scrub, but this can have a cleaning effect. However, it can also easily damage the enamel on the surface of the ceramic knife set, making it thinner and thinner.

Here's a hint of how to clean it:

The best way to clean is to remember to wipe off the large residue on the surface after each use, and clean the ceramic knife set with water. If you can maintain this good habit for a long time, you don't need any cleaning tools, and the ceramic knife set will keep it bright and shiny.

But there are many friends who go to rest or do other things after using it, and forget about cleaning the ceramic knife set. Wait until the next time you use it to clean the ceramic knife set. In this way, after a long time of soaking, many ceramic knife sets are colored, and they cannot be washed off with water.

It doesn't matter, you can squeeze a small amount of toothpaste on top of the ceramic knife set, and apply the toothpaste evenly to the surface of the ceramic knife set with your hands or a cotton swab. After about a minute, come back and clean the ceramic knife set with water, so that the stain on the ceramic knife set can be easily cleaned.

In addition, some dishes contain a lot of tannins, alkalis, caffeine and a small amount of volatile oils, vitamins, chlorophyll and other ingredients. Therefore, the ceramic knife set should be cleaned immediately after use.

Remind everyone: those who love to cook should also wash their utensils frequently. For ceramic knife sets that have been stained for a long time, they can be removed by repeated scrubbing with toothpaste; For ceramic knives with stains, heat them with rice vinegar or soak them in baking soda for a day and night, then shake them and rinse them repeatedly.

Advantages of ceramic knives.

1.High quality: From the point of view of the cutter body itself, because its raw material is a nano material "zirconia", it is made into a finished ceramic knife after multiple processes of grinding and matching the handle.

Therefore, its sharpness is more than ten times that of steel knives, so it also has the characteristics of high hardness, high density, high temperature resistance, anti-magnetization, anti-oxidation, etc., which are incomparable to traditional knives.

2.Health: Because of the special material of the ceramic knife, the ceramic knife will not react with the food when cutting the food, which can better maintain the original flavor and nutrients of the food, and it is not easy to breed bacteria, so the ceramic knife is also a suitable choice for cutting baby food.

3.Practicality: The excellent non-metallic properties of the ceramic knife make it have the characteristics of never rusting, and its own wear resistance is 60 times that of the metal knife, eliminating the trouble of sharpening the knife.

The design of ceramic knives is more scientific, and it fits more closely to people's hands than traditional knives, and at the same time, it is lighter in weight, which is convenient for women to use.

Disadvantages of ceramic knives.

1.It is not tough enough and is more brittle than steel knives, so it is not suitable for chopping ingredients or deboning.

2.Although the ceramic knife does not need to be sharpened, this is also one of its disadvantages, which will cause the ceramic knife to be unable to be maintained, and can only be used with more care in daily use.

The correct way to use ceramic knives.

1.In the process of cutting food, do not twist the ceramic knife at will, as this can easily cause the blade to break.

2.Do not use a ceramic knife to chop meat and bones, frozen food, etc., the most correct way to use a ceramic knife should be to cut.

3.Ceramic knives are more suitable for use on wooden or plastic cutting boards, rather than stone cutting boards.

4.Avoid heavy falls or external impacts.

5.Don't try to sharpen your own knives, as ordinary whetstones can damage ceramic knives, with the exception of diamond abrasives.

6.Ceramic knives cannot completely replace metal knives, so they should be used in combination.

How to maintain ceramic knives.

1.Do not wash the ceramic knife in the dishwasher, but slowly wipe it with your hands with detergent in warm water and let it dry naturally. Do not wipe with a metal cleaning ball such as a steel wool ball, as the blade may turn black due to the action of metal powder.

2.When the ceramic knife is stored, try to put it in a stable environment to avoid the ceramic knife from bumping or falling from a height.

3.Since the blade of the ceramic knife is very sharp, it is important to avoid children at home when placing it to avoid accidental injury.

4.Avoid placing it close to the fire source, the plastic handle will be deformed.

Yes. Mirrors are divided into foggy mirrors and mirrors. Different effects with different machines.

The zirconia ceramic knife cannot be repaired after it is broken, because it is sintered at high temperature, and it can still be used unless you change the shape of the broken knife and re-sharpen it after it is broken.

The disadvantage is that the hardness of the material is high, the toughness will decrease, this kind of knife is only suitable for cutting, not chopping, cutting, prying, easy to break. Ceramic knives, although called ceramic, are very hard and strong, and it is made of a kind of zirconia.

A method for growing cubic zirconia by cold crucible method, the matrix raw material is composed of zirconia and yttrium oxide, which is characterized by adding copper oxide to the matrix raw material of 1 10 1 30, and then put it into the corundum crucible for sintering after mixing, and make a mixture, adding thulium oxide to this mixture, making a mixed coloring material after mixing, loading the rest of the matrix material into the crucible, and then placing the mixed coloring material in the middle of the matrix material, using high-frequency heating, cold crucible descent method for growth, and the grown crystals are annealed again, That is, green cubic zirconia crystals are obtained.

Therefore, it should contain thulium oxide

Ceramic knives are not suitable for cooking food that needs to be chopped or chopped, so except for hard ingredients such as bones, coarse fish bones, and frozen meat, ceramic knives are not suitable for cooking.

At present, most of the ceramic knives on the market are processed from a nanomaterial "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.

Ceramic knives are known as "noble knives", as a product of modern high technology, with incomparable advantages of 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.

The 3mol yttrium oxide stabilized zirconia used in the production of ceramic knives is used as the main material, which is formed by dry pressing, gel, injection molding and other processes, and then sintered at high temperature, and then made by grinding and cutting the edge.

Ceramic knives cannot avoid the shortcomings of high brittleness and low toughness that are usually limited by ceramics themselves. Therefore, when using ceramic knives, you can't chop and chop like steel knives, especially hard objects such as bones, because after the ceramic knife is opened, the edge will become very thin, and it is easy to break or break.

Of course, ceramic knives also have certain advantages, no rust, more wear-resistant, sharpness can last a long time under normal use, especially suitable for fruits and vegetables.

The general one thousand five six, the nano one thousand three or so, the kiln generally uses the electric push plate kiln, I used to make alumina ceramics, fired into the kiln are the same, now discontinued, I also want to see what products are suitable, I hope to cooperate! 13838901185

First of all, zirconium oxychloride and yttrium oxide are dissolved into a solution of a certain concentration, and then ammonia is added to precipitate to obtain zirconium gel, and after washing and removing impurities, it is baked into zirconia in the electric furnace, after crushing, adding adhesive granulation, and then pressing into a knife embryo, which is fired into an electric furnace into shape, and then the blade (big blade, small blade), the surface is flat grinding or polishing, if you want a black knife, you must also dope carbon blackening, after the knife embryo is sharpened, choose the appropriate knife handle (ceramic, ABS plastic, rubber as you like), Then glue the knife and handle together, and the ceramic knife is ready.

Zirconia powder + mixed resin mixing--- pressure injection molding (approximate size of the blade) - deburring --- high temperature degumming (about 500 degrees, 20 hours) - high temperature sintering (1800 degrees, 25 hours) - blade surface polishing --- blade grinding.

--Install the shank and you're done.
