Anonymous users2024-02-06The stainless steel thermos cup was soaked in 84 disinfectant, and it was rusted locally, and it was no longer insulated, probably because the chloride ions in the 84 disinfectant corroded the surface of the stainless steel, resulting in rust and the failure of the thermal insulation effect.
Specifically, stainless steel is an alloy that is mainly composed of iron and contains elements such as about 12% chromium and 8% nickel. Since chromium, nickel, and chlorine are isotopes, the isotopes will be interchangeably assimilated, resulting in redox reactions and corrosion when the surface of stainless steel is in contact with chloride ions.
In addition, 84 disinfectant is a highly effective disinfectant based on sodium hypochlorite, and the main ingredient is sodium hypochlorite (Naclo), so it contains chloride ions. While the concentration of 84 disinfectant may not be high, it is still enough to cause corrosion to stainless steel.
In summary, the stainless steel thermos cup is soaked in 84 disinfectant and rusts and no longer insulated, because the surface of stainless steel has a redox reaction with chloride ions in 84 disinfectant, resulting in corrosion and the failure of thermal insulation effect.

Anonymous users2024-02-05Stainless steel is susceptible to chloride ions.
Corrosion, because chromium, nickel, and chlorine are isotopes, and the isotopes will be exchanged and assimilated to form the corrosion of stainless steel. From Encyclopedia 84 disinfectant.
It is a sodium hypochlorite.
The main ingredient is sodium hypochlorite (Naclo). Colorless or light yellow liquid with available chlorine content. It is widely used in the sanitation and disinfection of hotels, tourism, hospitals, food processing industries, homes, etc., and it is also encyclopedia 84 that should have chloride ions, but the concentration may not be high (no ...... has been detectedSo this is self-inflicted......Satisfied.

Anonymous users2024-02-04The stainless steel material generally used as a thermos cup is 304 stainless steel, which will not rust at room temperature and under low acid and alkali conditions, but under the immersion of salt, intergranular corrosion will occur, which is a normal phenomenon and does not affect the use.
Rusty thermos cup is a metal cup, to solve the problem of rust, first of all, change the use habits of the thermos cup, do not contain salty liquid, especially high salty liquid, short time to load, to pour out in time, repeated cleaning, do not overnight. If it has rusted, consider using a cleaning brush to gently remove the rusty layer on the surface, revealing a silver-white stainless steel matrix.

Anonymous users2024-02-031. The newly bought stainless steel thermos cup should be soaked in an appropriate amount of warm water and boiling water for 5 minutes for the first time, and then pour baking soda or rice water after selling the fan to carry out secondary decontamination treatment, because the new thermal insulation cup may contain a little polishing powder, and you can also pour white vinegar to disinfect it.
2. When pouring water into the cup, avoid pouring it too full, because the lid of the thermos cup has a certain thickness, and if the water is poured too full, it will overflow when the lid is covered.
3. Before using the newly bought thermos cup, it is recommended to scald the inside and outside of the thermos cup with hot water or warm water to disinfect it at high temperature.
4. It is necessary to avoid the car source of the thermos cup from being bumped or impacted, otherwise it may cause damage to the inside of the thermos cup, affect its thermal insulation performance, and reduce its service life.

It is normal for general stainless steel products to have a certain amount of oil stain on the wall of the cup due to grinding, rust prevention and other reasons, so it should be cleaned and soaked before use.
2. Ferric oxide.
There is also a situation where ferric oxide is present, and it does not matter if it enters the body, there is no need to worry.
3. Unqualified stainless steel products are used.
There is also a situation where unqualified stainless steel products are used, and after high temperature, there will be dissolved metal ions absorbed into the blood, such as chromium, nickel and other substances are excessive, which is not good for the human body. Do not use substandard stainless steel products.

There are two methods, one is to use passivation paste, which is specially used to clean short stainless steel welds, which only need to be applied to the weld for 20 minutes and wiped off; The other is for more welds, first put the workpiece into the mixture of nitric acid and hydrofluoric acid to soak and clean for 15 minutes, take it out and rinse it with water, and then put it into nitric acid to passivate for 20 minutes, take it out and rinse it clean.
Differences: 1. Different degrees of corrosion resistance: 316 stainless steel contains MO, which has better corrosion resistance than 304 stainless steel in a high-temperature environment, so in a high-temperature environment, engineers generally choose 316 material parts. >>>More
