Stainless simbi imhando yesimbi yakakwira-alloy inokwanisa kuramba kukoromoka mumhepo kana kemikari inoita corrosive medium.Iyo ine yakanaka yepamusoro uye yakanaka corrosion resistance.Iyo haidi kurapwa pamusoro senge color plating, asi inoshandisa iyo inherent pamusoro zvimiro zvesimbi isina tsvina.Inoshandiswa muA type of multifaceted steel.
Mazuva ano, zvigadzirwa zvesimbi zvisina simbi zvakashandiswa zvakanyanya muindasitiri uye hupenyu.Saka sei kusiyanisa chokwadi chesimbi isina tsvina?Pazasi, mupepeti weBritish anokutora kuti unzwisise:
1. Chemical qualitative nzira
Iyo kemikari yemhando yemhando inzira yekuzivisa yekuona kana iyo magineti Stainless simbi ine nickel.Nzira yacho ndeyekunyungudutsa chidimbu chesimbi isina tsvina mu aqua regia, diluted acid solution nemvura yakachena, kuwedzera ammonia mvura kuti iite neutralize, uye zvinyoro nyoro jekiseni nickel reagent.Kana paine chinhu chitsvuku chevelvet chinoyangarara pamusoro pemvura, zvinoreva kuti simbi isina tsvina ine nickel;kana pasina chinhu chitsvuku chevelvet, zvinoreva kuti hapana nickel musimbi isina tsvina.
2. Nitric acid
Chinhu chinocherechedzwa chesimbi isina simbi ndeyezvayo marara ekuramba kudzika uye kudzikisa nitric acid.Tinogona kushandisa nitric acid kudonhedza pane zvigadzirwa zvesimbi isina simbi, iyo inogona kunyatsosiyaniswa, asi isu tinofanirwa kutarisisa kuti masimbi epamusoro-kabhoni 420 uye 440 masimbi ane ngura zvishoma panguva yekuedzwa kwenitric acid point, uye simbi dzisina ferrous. ichabva yasangana yakanyanyisa nitric acid.corroded.
3. Copper sulfate point test
Bvisa oxide layer pasimbi, isa donhwe remvura, uipuse nemhangura sulfate, kana ikasachinja ruvara mushure mekukwesha, kazhinji isimbi isina tsvina;alloy simbi.
4. Ruvara
Rudzi rwepamusoro rweasidhi-yakashambidzwa simbi isina tsvina: chrome-nickel simbi isina tsvina ine silvery jena jena ruvara;chrome Stainless simbi ine grey chena uye inopenya;ruvara rwe chrome-manganese-nitrogen simbi isina tsvina yakafanana neye chrome-nickel simbi isina tsvina uye zvishoma zvishoma.Rudzi rwepamusoro rwesimbi isina tsvina isina kugadzirwa: chrome-nickel simbi yebrown-chena, chrome-simbi ine brown-dema, uye chrome-manganese-nitrogen itema.Cold-rolled unnnealed chrome-nickel Stainless steel ine sirivheri-white white reflective surface.
