Waiting chairs, stainless steel or iron?
Iron: Iron reacts with dilute sulphuric acid to produce ferrous sulphate, producing bubbles. So by acid rain area, outdoor iron chair is not very good, easy corrosion of iron. Iron and oxygen or water vapor generated by the reaction of Fe O, as FeO Fe O. Therefore, if the sun or rain, or only indoors, such as airports, stations, cleaning workersUse water or disinfect water to wipe the chair, so that you can accelerate the oxidation and corrosion of iron.Therefore most of the airport chair, waiting chair, chair is stainless steel, Aluminum Alloy steel as raw materials.
Comparison of stainless steel and iron material: stainless steel: the resistance of air, steam, water and other weak corrosive medium, with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel.The test shows that the steel in the atmosphere, water and other medium and weak acid oxidizing medium, the corrosion resistance increased with the increase of Cr content in steel, when the chromium content reaches a certain percentage, the steel corrosion resistance mutation from rust to rust, corrosion and corrosion resistance to never.
Waiting chairs are mainly used indoors or outdoors, and iron waiting chairs are sure to rust if they are used outdoors. As for environmental protection, stainless steel is not easy to wear, never rust, strake is Aluminum Alloy strake, electrochemical treatment, the bottom beam is 2mm40*80mm steel pipe, spray paint outdoor powder, can withstand the wind and rain, sunshine test.
