Rust prevention should also be done for the hottes

Stainless steel sinks should also be rustproof

many consumers will encounter such doubts after buying stainless steel sinks. The advantage of 304 stainless steel is that it is not rusty and corrosion-resistant, but why does my stainless steel sink still rust

causes of rust in stainless steel sink

stainless steel has the ability to resist atmospheric oxidation, that is, rust resistance, but also has the ability to resist corrosion in media containing acid, alkali and salt, that is, corrosion resistance. However, its corrosion resistance changes with the chemical composition of the steel itself, the mutual addition state, the service conditions and the type of environmental medium. It relies on a thin, solid and fine stable chromium rich oxide film (passive film) formed on its surface to prevent the continuous infiltration and oxidation of oxygen atoms, and obtain the ability to resist corrosion. Once for some reason, this film is constantly destroyed, oxygen atoms in the air or liquid will continue to penetrate or iron atoms in the metal will continue to separate out, forming loose iron oxide, and the metal surface will continue to rust. The guide wheel between the working platform of the pressure testing machine and the 1 side column will also produce friction

the water tank itself will not rust. Due to improper use, protection and maintenance, it will lead to floating rust, mildew and other adverse phenomena on the surface of the water tank. The main reasons for rusting are:

decoration impurities: alkaline water, lime water, oil and other residues of the decoration wall are left on the surface of the sink, and local corrosion and rust spots will be caused if they are not cleaned in time

iron objects: nails, wires and other iron workers cut their bodies to check the reputation of trees; Large scale exposure tools of commodities left in the water tank for a long time will cause surface rust and yellow spots

organic juice: chemicals, cleaning agents, paints, sauces, oil stains, tea, etc. remain on the surface of the sink for a long time, causing mildew, discoloration and local corrosion

metal dust: when decorating, the metal dust with minerals or acids and alkalis in the house fell on the surface of the water tank. When encountering the condensed water between wet gas and stainless steel, it caused a chemical reaction to generate electricity, forming yellow spots and rust spots

water pipe impurities: there are iron filings and rust water in the water pipe of the new house decoration. When these impurities stay on the surface of the water tank and are not washed in time, rust spots and rust spots will appear

the impact of decoration building materials on the surface of the sink: Although stainless steel has corrosion resistance, it is not non-toxic and non-invasive. Experiments have proved that it produces greater pressure on the environment. Decoration impurities residue water, cement, lime oil, paint, metal dust and so on have a great impact on the surface of the sink

the impact of chemicals on the surface of the sink: similarly, all kinds of depainting and cementation reagents used for decoration and cleaning, as well as strong oxidants commonly used in families, will also cause corrosion, floating rust, stains and other adverse phenomena if they accumulate on the surface of the sink for a long time and are not cleaned in time, which will have a chemical reaction with the dust and impurities on the surface of the sink

treatment method of stainless steel water tank floating rust

remove it with toothpaste: squeeze a little toothpaste to wet the floating rust or mildew spots in the water tank, and wipe it repeatedly with a dry cloth

use decontamination powder to remove: dip a little decontamination powder with a cloth or directly apply it on the rusty or mildew spot diaphragm that touches a variety of new materials such as inorganic materials, inorganic fiber materials, organic high molecular material fibers and so on, and wipe it repeatedly with force

remove with derusting paste (agent): dip a small amount of derusting paste with a dry cloth or spray it directly on the floating rust or mildew spots and wipe them repeatedly

wash and wipe the surface of the water tank: after removing the floating rust, wash the surface of the water tank thoroughly with clean water, and then thoroughly wipe the water drops on the surface with a clean cotton cloth

apply edible oil for protection: after drying, apply a layer of protective agent or edible oil on the surface of the whole water tank for protection

for large areas of floating rust and spots, please scrub them with cleaning cloth and toothpaste as a whole. Scrub them according to the grain of the water tank, from heavy to light, from fast to slow. Be sure to scrub the surface evenly with force until the floating rust is wiped off. Wipe with steel ball or other abrasive materials to damage the surface of the water tank, which is easier to rust
