Waiting chair material

1 、waiting chair is mainly used in indoor or outdoor, if you use the iron chair waiting outdoors will rust. As the stainless steel is environmental protection, not easy to wear and tear, never rust, strake is aluminum alloy strips and electrochemical processing, at the bottom of the beams is 2mm thick 40*80mm pipe, outdoor paint powder spray, can withstand wind and rain, the test of sunshine.

2 、Comparison of stainless steel and iron:

Stainless steel: the resistance of air, steam, water and other weak corrosive media, with stainless steel known as stainless steel; while the resistance to chemical corrosion medium (acid, alkali, salt and other chemical etching) of the corrosion of steel called acid resistant steel.

Experiments show that the steel in the air, water and the weak medium and nitric acid oxidation medium, the corrosion resistance increased with the increase of Cr content in steel, when the chromium content reaches a certain percentage, mutations in the corrosion resistance of steel, namely from easy to rust to is not easy to rust, never corrosion resistance to corrosion.

Iron: Iron reacts with dilute sulfuric acid to produce ferrous sulfate, which is produced by air bubbles. So by acid rain area, outdoor iron chair is not very good, easy corrosion of iron.

Use 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 which is used stainless steel, Aluminum Alloy and steel as raw materials.
