Yog tias koj yuav lub raj mis stainless hlau dej thiab xav txiav txim seb nws puas yog ua los ntawm 304 stainless hlau, koj tuaj yeem siv cov txheej txheem qhia ceev hauv qab no:
Kauj Ruam Ib: Sib Nqus Sib Nqus
Muab cov hlau nplaum tso rau saum lub khob dej thiab saib seb lub khob dej puas nyiam cov hlau nplaum thaum lub sijhawm txav cov hlau nplaum tas li. Yog tias lub khob dej tuaj yeem nqus cov hlau nplaum, nws txhais tau tias nws cov khoom muaj hlau, uas yog, nws tsis yog 304 stainless hlau.
Kauj Ruam 2: Kos xim
Cov xim ntawm 304 stainless hlau yog lub teeb, zoo ib yam li dawb dawb, tsis yog dawb huv los yog daj thiab lwm yam xim. Yog tias koj pom tias lub raj mis dej tsis muaj steel muaj xim zoo nkauj lossis ci dhau, ces nws tsis yog 304 stainless hlau.
Kauj Ruam 3: Saib xyuas lub chaw tsim khoom lub logo
Feem ntau cov tuam txhab lag luam yuav luam lossis muab tshuaj txhuam lawv tus kheej cov cim lag luam thiab cov ntaub ntawv tsim khoom ntawm cov fwj dej tsis muaj steel hlau. Koj tuaj yeem siv lub cim lag luam lossis lub tshuab luam ntawv barcode los kuaj xyuas cov ncauj lus kom ntxaws ntawm cov khoom, suav nrog cov ntaub ntawv siv, hnub tsim khoom thiab cov ntaub ntawv tsim khoom, thiab lwm yam, los txiav txim seb nws puas yog 304 stainless hlau.
Kauj Ruam 4: Siv cov tshuaj reagents los kuaj
Yog tias txoj kev saum toj no tsis tuaj yeem txiav txim siab, cov tshuaj reagents kuj tuaj yeem siv los kuaj. Ua ntej, muab ib qho me me ntawm cov khoom siv hlau tsis muaj steel, tsau rau hauv qhov sib xyaw ntawm 1 ml ntawm nitric acid thiab 2 ml ntawm hydrochloric acid rau ntau tshaj 30 vib nas this, thiab tom qab ntawd saib seb puas muaj xim lossis zoo sib xws oxidation tshwm sim.
