Edit the classification of this part of the sink.

Kitchen sinks are divided into cast iron enamel, ceramics, stainless steel, artificial stone, steel plate enamel, acrylic, crystal stone sinks and so on. According to the style, it is divided into single basin, double basin, large and small double basin and special-shaped double basin. ① The steel plate enamel sink is beautiful. ② Ceramic sink is durable and wear-resistant. ③ The artificial stone sink is easy to form, and the corners are seamless. 4 If you pay attention to the overall color of kitchen utensils, you can choose acrylic sink. It is not only white, but also other sinks with kitchen utensils.

The color of. ⑤ Crystal stone sinks are mostly iron gray and beige, so be careful when using them. Sharp knives and rough things will scratch the surface and destroy the finish. ⑥ Stainless steel sinks have been popular for a long time. As far as the present situation is concerned, stainless steel sinks are widely used. This choice is not only because the metal texture of stainless steel is quite modern, but more importantly, stainless steel is easy to clean, the panel is light and thin, and it also has the advantages of corrosion resistance, high temperature resistance and moisture resistance. In terms of price, it ranges from several hundred yuan to several thousand yuan. ⑦ Cast iron enamel sink is durable, but it is rare in the market. Occasionally, there are imported products, the price is more than several thousand yuan, and ordinary people are afraid to ask.

Edit the process of stainless steel sink in this kitchen:

One about welding and stretching:

As far as the current sink market is concerned, there are three kinds: integral stamping (also called integral stretching or combined stretching), roll welding (also called bottom welding) and butt welding. Both belong to the welding pot. Then, I personally think that under the current technical conditions, the bottom welding pot is the best. The reason is that the whole stretched tank generally needs high temperature annealing, which is generally above 1200 degrees. After such treatment, the sink sinks. Secondly, the thickness of steel plate commonly used at present is 0.8- 1.0cm. If it exceeds this thickness, it can be said that even a 500-ton hydraulic press is useless. So from this point of view, it is difficult to ensure the thickness of the whole drawing basin; Thirdly, in terms of edge treatment, the overall stretched basin is generally single-layer flanging. On the one hand, it is likely to cut the hands of the installer. The most important thing is that there is no "rib", the bearing capacity is not good enough, and it is difficult to stop water. Fourth, overall stretching is possible, and the panel is difficult to level off; For butt welding pots, the most difficult thing to do is to ensure the flatness of the pot surface. If it can be guaranteed, it is really the best way, because it is the same material as the whole stretching, and it can also solve the stretching problem of the conjoined stretching. But at present, I see that many butt welding pots on the market are perfect; For bottom welding, I personally think it is the most mature technology under the current technical conditions, provided that it must be numerical control welding. Before Guardian introduced German technology a few years ago, it was all manual welding by workers. I have seen this kind of manual welding basin in the warehouse of the factory, and the welding points are very uneven. In fact, it is constantly repairing the traces left by welding, and CNC welding avoids the phenomenon of virtual welding and missing welding. Remind everyone that when choosing a basin, you can take a closer look at whether there is a fine seam at the welding place. If there is, it must be a virtual welding. Then, over time, it leaked. The disadvantage of this welding method is that it uses too much material and washes away two steel plates. When buying a sink, you can touch the basin wall with your hand to see if there is any bulge. High-end sinks don't have bumps.

Second, about the surface treatment of the sink:

At present, there are four kinds: frosting (wire drawing), sandblasting (matte pearl silver surface), polishing (mirror surface) and embossing. Among them, the frosted wire drawing basin is stainless steel, and its advantage is that it is getting newer and newer with use, and the wire drawing is actually made of grinding wheel. This surface treatment is my favorite; The effect of sandblasting electrochemical basin is matte pearl. Its advantages are oil-free and beautiful. It should be said that it is more oil-proof, but it can't keep up with embossing and sanding in terms of wear resistance. Polishing is the most easily scratched basin, which looks good, has been used for a long time, and is the most troublesome and ugly, so it is basically not used in China at present; Embossing uses embossing materials, but the cost is relatively high and it is very wear-resistant. So I think the ideal surface treatment methods are sand blasting and sanding. But please remember: stainless steel objects should not be polished with steel balls, no matter what surface treatment will leave scratches.

Three about the corner treatment of stainless steel sink:

At present, there are many ways to deal with the corners of stainless steel sinks on the market, such as square corners, rounded corners, thin edges, beveled edges, floating edges and so on. Among them, the square corner of the flat edge can be used as the upper basin or the lower basin, but because it is a square corner, on the one hand, the visual angle effect is not very good, and at the same time, its load bearing is not very strong, and it is easy to fold the corner during transportation, so it is used less now; On the one hand, flanging enhances the flatness of the sink, on the other hand, the reinforcing ribs make the sink more loaded and have a good water retaining effect, so as to prevent water from flowing to the cabinet table. Now many sink manufacturers like this side technology, but it must be double-layered to be effective. As you can see in the market, many of them are unilateral. At the same time, the edge of the high-grade stainless steel sink is generally flat and there is no big bend.

Four about the splash at the bottom of the sink:

At present, some sinks on the market are painted with different colors and materials, claiming that they can prevent sweat and absorb moisture. What happened? In fact, the main purpose of spraying coating on the bottom of the sink is to prevent temperature difference from condensation, protect the cabinet and reduce the noise of falling into the water. Moisture absorption is only a secondary function or a different way of saying it. When quick-frozen food is put into the sink or in wet weather in spring and summer, water vapor will condense at the bottom of the basin to form water droplets because of the low temperature of the sink. Dropping water will cause the cabinet to get wet. Spraying a suitable coating on the bottom of the sink can reduce or even eliminate the temperature difference and destroy the formation of water droplets. High-quality coating also has a certain moisture absorption function to protect cabinets from flooding. But at present, the bottom of the washbasin on the market is mostly ordinary paint, which does not absorb moisture and has little dew-proof function, but is empty. The importance of choosing a good sink is the core of the kitchen. According to statistics, the utilization rate of sink is the highest among all kinds of kitchen supplies. In the preparation and cleaning work before and after meals, more than 65% of the time is directly related to the sink, so it is very important to choose a beautiful, good performance and clean sink for creating a comfortable and warm kitchen. Advantages of stainless steel sink stainless steel material is known as one of the important inventions to improve human living standards in 2 1 century. It is natural and unique to use stainless steel as a sink, which has an irreplaceable role for other materials. Acid and alkali resistance, oxidation resistance, beautiful surface, can always keep bright as new and durable. Strong and elastic, impact-resistant and wear-resistant, and does not damage the cleaned utensils. Multifunctional and light, it can be made into different shapes and styles through precision processing, and can be matched with various kitchen countertops. Correct maintenance instructions for water tank 1. Clean immediately after use, dry and store. Try not to let water droplets stay on the surface of the sink, because water with high iron content will lead to floating rust, and water with high mineral content will produce white film. 2. If mineral deposits appear at the bottom of the sink, they can be removed with diluted vinegar and washed with water. 3. Do not let hard objects or rusty objects touch the sink for a long time. 4. Don't leave the rubber pad, wet sponge or cleaning cloth in the sink all night. 5, pay attention to fluorine-containing household items, bleach, food and silver-containing cleaning supplies and cleaning supplies containing sulfur and hydrochloric acid are potentially harmful to the sink. 6. Pay attention to the gas released by bleach or chemical cleaner in the kitchen cabinet, which will corrode the bottom of the sink. 7. If photographic chemicals or soldering iron flux come into contact with the sink, the sink must be cleaned immediately. 8. Don't put paulownia, mayonnaise, mustard and pickled food in the sink for a long time. 9, can't use iron ring or rough cleaning to clean the sink. 10, any wrong use or incorrect cleaning method will cause damage to the sink. Proper maintenance of the sink [1] 1. When using the sink for the first time after the renovation of the new house, drain the water for 5- 10 minutes, drain the water containing rusty substances in the water pipe, and wipe the surface of the sink with a soft cloth. It is best to test the water 2-3 times every other day to ensure that the rusty water is discharged cleanly. 2. Construction personnel are required to wrap the sink in plastic bags after installation, and then open the plastic bags for use after renovation. 3. Don't let soft iron or rusty products contact the sink for a long time. Don't use strong acid and alkali to clean the items in the sink. Clean the can after each use and dry it with a rag. 4. If floating rust appears on the surface of the sink, it should be wiped with talcum powder, derusting water or 300# sandpaper in time. Remove rust spots with talcum powder: put a handful of talcum powder in a dry sink and wipe the rust spots with a clean and soft rag; (Remove with derusting water: gently wipe the rust spots with a clean and soft rag dipped in a small amount of derusting water); (Fold it into a small angle with 300# sandpaper and wipe it at the rusty spot). Any product needs your maintenance. If you do the above aspects in use, your stainless steel sink will always be new, and it will be a good partner for your family to cook delicious food. Stainless steel is the best material for making sinks. The sink is a long-term product-stainless steel is extremely strong and will not be damaged over time. 2. The sink contacts the most water-stainless steel will not be corroded and rusted by water. 3, the sink often deals with hot pot, hot water, etc. -Stainless steel has thermal protection function, which will not melt or burn. Expensive glass products should also be washed in the sink-stainless steel will not wear glass products and porcelain. 4. The sink is exposed to the sunshine outside the window every day-stainless steel is not affected by strong light. The sink is a part of the home environment-the quiet beauty of stainless steel is an elegant taste. A lot of food needs to be washed in the sink-stainless steel is easy to clean and very hygienic.
