Stainless steel sinks typically use several materials:; 304 is the abbreviation for SUS304; 304DDQ  (18/10) Stainless steel is a good material for stainless steel sinks. 304DDQ stainless steel adopts a special process to contain chromium; The quantity has increased by 2 points (SUS304 steel plate is 18/8); ,   304DDQ is 18/10) That is to say,  The nickel content in 304 stainless steel is 18%.   The content of 304DDQ stainless steel is 8%;; The nickel (Ni) content in the improved 304DDQ stainless steel is 18%; The content of chromium (Cr ) is 10%. Steel plates not only have high brightness, no discoloration, and a beautiful appearance, but also have good ductility, toughness, and corrosion resistance.

The thickness of the sink board is 0.8-  Between 1mm, the thicker the steel plate, the higher the requirements for casting equipment and processing technology. The thicker the material, the higher the stamping tonnage of the sink stamping machine and the higher the requirements for raw materials. (Usually, stainless steel sink manufacturers use 304 steel plates, even for low-grade 201.); 202 steel plate, if the sink is made of 304DDQ stainless steel imported from Japan, the steel plate has high brightness; Corrosion resistance and excellent ductility. )  Currently, some sinks have produced sinks with a thickness of 2mm. So you need to tailor it according to the actual situation of your kitchen.

The surface treatment process of stainless steel sinks is also an essential indicator when purchasing

1. Pearl surface.

. Some people also call it pearl silver surface, frosted surface, pearl frosted surface, etc. It is made of chemical electrolytes used for surface treatment (in other words, similar to electroplating). This surface treatment has a simple process, low technical content, and low production cost in all production. The products manufactured also have lower prices. Currently, over 90% of the nearly 2000 manufacturers in China fully adopt this process for production. Many online brands also use this method; The quality of craftsmanship seizes the low-end market. But the biggest flaw of this surface is its lack of scratch resistance. The surface is prone to scratches, and in severe cases, coating detachment may occur. So many large-scale enterprises are gradually replacing this process with other techniques. For this process, it is not recommended for the manufacturer of Xijun stainless steel sink to choose it, as the disadvantages outweigh the advantages.

2. Matte surface. Also known as pearl sand noodles. It is to uniformly and rapidly smash small sand particles onto the surface of the sink, forming tiny grooves on the surface that are extremely fine; (It's hard for the human eye to tell); ,   And by increasing the hardness of the sink surface, it also enhances its scratch resistance. The principle is equivalent to shot peening in mechanical processing. This treatment generally requires that the wall thickness of the board should not be too thin; This method is commonly used for overall stretching sinks.

3. Drawing surface. Also known as silky smooth surface. It means adopting -  -The equipment for wire drawing repeatedly draws on the surface of the sink (equivalent to grinding in mechanical processing). Make its surface form fine silk marks, and the surface is extremely smooth. It has a strong sense of clarity and visual appeal. Because it is directly brushed on the surface of the sink, the requirements for the board are extremely high. Sometimes, fine particles may appear on the surface of domestically produced sheet metal during wire drawing, which can affect its appearance. Therefore, most of the brushed sheets are made of imported sheets.

4. Embossed surface. It is to press regular patterns on the surface of the sink or directly use embossed plates to press (equivalent to patterned steel plates used on pedestrian overpasses on the road); ,   Then use pearl surface treatment method for surface treatment. The visual effect of the relief surface is also good, but long-term oily smoke in the kitchen can accumulate dust in the pattern, making it difficult to clean.

5. Mirror finish. Repeatedly polish the surface of the sink to make it look like a mirror. This type of treatment is not suitable for most households and is prone to scratches during use.
