Description

Ceramic knives with sintered coating

technical field

The utility model relates to a ceramic knife, in particular to a ceramic knife with a sintered coating.

Background technique

Knives made of ceramic materials not only have the advantages of lightness, sharpness, no rust, easy cleaning and no odor residue when cutting food, but also have high hardness and high wear resistance, which can greatly reduce Its passivation or wear, so it has been gradually and widely used in various knives at home.

A known ceramic knife mainly includes a knife body and a handle. The knife body has a knife body and a knife neck extending from the knife body. The knife handle is sleeved on the knife neck to be combined into a ceramic knife. However, when the ceramic knife is dropped or impacted by an external force, the neck portion tends to bear most of the shear stress, thus causing the ceramic knife to break from the neck.

Therefore, in order to solve this problem, the industry increases the thickness of the knife body and the knife neck to maintain the structural strength of the knife neck; Material usage cost and manufacturing cost, and when the thickness of the blade part increases, it does not meet the light and thin requirements for cutting; it really needs to be improved.

Utility model content

In view of this, the main purpose of the present utility model is to provide a ceramic knife with a sintered coating, which can effectively prevent brittle fracture of the ceramic knife body by forming the sintered coating on the surface of the ceramic knife.

In order to achieve the above purpose, the utility model provides a ceramic knife with a sintered coating, which includes a ceramic knife body and a sintered coating. The ceramic knife body has a blade body and a knife neck extending from one end of the blade body; Combined between the blade and the neck.

Further, the sintered coating is combined with the blade body and the blade neck on one side.

Further, the sintered coating is double-sidedly combined with the blade body and the blade neck.

Further, the sintered coating is formed on the ceramic cutter body by transfer printing.

Further, the sintered coating is formed on the ceramic cutter body in the manner of color painting.

Further, the sintered coating is formed on the ceramic cutter body by coating.

Further, the ceramic knife also includes a knife handle, which is sleeved on the knife neck and partially covered on the sintered coating.

Further, the processing temperature of the sintering method is higher than 500°C.

Compared with the prior art, the ceramic knife with sintered coating of the present invention is formed on the ceramic knife body by sintered coating, which can not only achieve a tight bonding effect and is not easy to fall off, but also improve the overall aesthetics.

Detailed ways

The detailed description and technical content of the present utility model will be described as follows with the accompanying drawings, but the attached drawings are only for illustration purposes and are not intended to limit the present utility model.

Please refer to FIG. 1 to FIG. 4 , the utility model provides a ceramic knife with a sintered coating, which mainly includes a ceramic knife body 10 and a sintered coating 20a.

The ceramic knife body 10 is made of ceramic material, and mainly includes a knife body 11 and a knife neck 12. The knife body 11 has a knife edge 111 and a knife back 112 formed behind the knife edge 111. The knife neck 12 extends outward from the upper right position of the knife back 112. Formed, and make the longitudinal width distance of knife neck 12 less than the longitudinal width distance of blade body 11.

The sintered coating 20a of the present embodiment is formed on the ceramic cutter body 10 in a transfer printing manner. First, the pattern layer 20 is taken. The pattern layer 20 mainly includes a plastic film 21, a colored glaze pattern 22 and a paper sheet 23. The colored glaze pattern 22 is between Between the plastic film 21 and the paper sheet 23, and the colored glaze pattern 22 is mainly made by mixing ceramic color glaze material with ink, wherein the ink is mainly composed of metal oxide inorganic pigments and solvents.

Then the pattern layer 20 of appropriate size is immersed in clear water for about 3-5 minutes, so that the colored glaze pattern 22 and the plastic film 21 can be peeled off from the paper sheet 23 together (as shown in Figure 1).

The color glaze pattern 22 and the plastic film 21 in the aforementioned pattern layer 20 are transferred between the knife body 11 and the knife neck 12 of the ceramic knife body 10, and the color glaze pattern 22 and the plastic film 21 can be pressed and bonded on one side of the ceramic On the cutter body 10 (as shown in Figure 2). In the same way, the colored glaze pattern 22 and the plastic film 21 can also be pressed and bonded on both sides of the ceramic cutter body 10 (as shown in Figure 3 ), so that two surfaces corresponding to each other are formed on the two sides of the ceramic cutter body 10. The sintered coating 20a (see Figure 4).

Thereafter, the pattern layer 20 and the ceramic cutter body 10 are subjected to drying treatment at the same time; the drying treatment method can be air drying or heating drying.

Finally, the ceramic cutter body 10 pasted with the colored glaze pattern 22 and the plastic film 21 is sent into the kiln for sintering processing or firing processing. During the treatment process, the plastic film 21 will be melted at high temperature, and the colored glaze pattern 22 will be fired to form a sintered coating 20a on the ceramic cutter body 10 (as shown in FIG. 4 ).

In addition, the ceramic knife with sintered coating of the present invention further includes a handle 30, which is sleeved on the aforementioned knife neck 12 and partially covered on the sintered coating 20a.

Further, the colored glaze pattern 22 of the ceramic knife with sintered coating film of the present invention can be in addition to the above-mentioned transfer printing method, and can also be straddled and formed between the blade body 11 and the knife neck 12 by means of painting or coating (Fig. not shown in ), and obtain the aforementioned sintered coating film 20a through high-temperature sintering.

To sum up, the ceramic knife with sintered coating of the utility model can indeed achieve the expected purpose of use and solve the existing shortcomings.

The above are only preferred embodiments of the present utility model, and are not intended to limit the implementation scope of the present utility model. That is, all equivalent changes and modifications made according to the claims of the utility model are covered by the patent scope of the utility model.
