I believe that in the current cognition of most people, stainless steel sink is made of stainless steel, that will not rust like stainless steel, if rust is a problem of steel, in fact, it is not, this is a one-sided wrong view. In fact, it may also rust under certain conditions. Under what circumstances is the sink prone to rust? And what do you have to do so that it doesn't rust?
Causes of sink rust
1. Generally, stainless steel sinks will appear rust, because of the surface of rust, floating rust is some metal substances, organic substances and acid and alkaline chemicals long-term residue in the sink, long-term and sink condensation, the two into a microbattery, triggered an electrochemical reaction, protective film is damaged, called electrochemical corrosion.
2. The surface of the sink is adhered to vegetable juice, noodle soup, acidic liquid, etc., and organic acids will corrode the metal surface in a relatively long period of time.
3. The surface of the sink adheres to substances containing acids, alkalis and salts (such as alkaline water and lime water splashes on the decoration walls), causing local corrosion.
So to keep the sink from rusting, there are also the following suggestions:
1. The surface of the sink must be kept clean and tidy to avoid erosion of the surface by adhesions.
2. The selected 304 stainless steel material should meet the national standard, and it cannot meet the requirements of 304 material, which is more prone to rust in the stainless steel sink.
