Kana iwe ukatenga bhodhoro remvura resimbi isina simbi uye uchida kuona kuti rakagadzirwa ne304 simbi isina tsvina, unogona kutora dzinotevera nzira dzekuzivikanwa dzinotevera:
Danho Rokutanga: Magnetic Test
Isa magineti pamusoro pegoko remukombe wemvura uye tarisa kana kapu yemvura inokwezva magineti uchigara uchifambisa magineti. Kana kapu yemvura inogona kutora magineti, zvinoreva kuti zvinhu zvayo zvine simbi, kureva kuti, haisi yakachena 304 simbi isina tsvina.
Nhanho yechipiri: Tarisa Ruvara
Rudzi rwe304 simbi isina simbi yakareruka, yakafanana ne-off-white, pane yakachena yakachena kana yero uye mamwe mavara. Kana iwe ukaona kuti Stainless simbi bhodhoro remvura rine ruvara rwakajeka kana kupenya zvakanyanya, saka pamwe haisi 304 simbi isina tsvina.
Danho rechitatu: Cherekedza logo yemugadziri
Vazhinji vagadziri vanodhinda kana kunamira yavo yekutengeserana uye ruzivo rwekugadzira pamabhodhoro emvura esimbi. Unogona kushandisa mucherechedzo kana barcode scanner kutarisa ruzivo rwakadzama rwechigadzirwa, kusanganisira ruzivo rwechigadzirwa, zuva rekugadzira uye ruzivo rwemugadziri, nezvimwewo, kuona kana iri 304 simbi isina tsvina.
Nhanho 4: Shandisa reagents kuyedza
Kana iyo nzira iri pamusoro isingagone kutsanangurwa, kemikari reagents inogona zvakare kushandiswa kuongororwa. Kutanga, tora chidimbu chidiki chesimbi isina tsvina, wonyika mumusanganiswa we 1 ml ye nitric acid uye 2 ml yehydrochloric acid kweanopfuura masekonzi makumi matatu, uye woona kana kupendeka kana kwakafanana oxidation reactions inoitika. Kana pasina kuita kana kungoita kushoma oxidation, inogona kunge iri 304 simbi isina tsvina.
Kupfupisa, zviri pamusoro apa nzira dzinoverengeka dziri nyore, dzinokurumidza uye dziri nyore-kushanda dzekukubatsira kuona kana kapu yemvura yesimbi isina tsvina yakagadzirwa ne304 simbi isina tsvina. Kana uchine zvinokunetsa, unogona kutibvunza chero nguva.
