Simbi isina tsvina inofanira kujairana nesu tose.Muhupenyu hwedu, zvinhu zvakawandisa zvakagadzirwa nesimbi isina tsvina.Paunenge uchitenga zvigadzirwa zveimba yesimbi isina tsvina, tinogona kazhinji kuona nhamba dzenhamba pamberi pezwi rokuti "simbi isina tsvina".Nhamba dzinonyanyozivikanwa i304 uye 316. Nhamba idzi dzinorevei?Tinofanira kusarudza ipi?
Stainless simbi haisi kungoita ngura chete
Isu tose tinoziva kuti chikamu chikuru chesimbi isimbi.Iyo kemikari yesimbi inoshanda zvakanyanya, uye zviri nyore kuita nemakemikari nezvinhu zvakatenderedza.Zvinonyanya kuita ndezvekuti oxidation, apo iron inopindirana neokisijeni mumhepo, iyo inowanzonzi ngura.
Wedzera kumwe kusvibiswa (kunyanya chromium) kusimbi kuti uite simbi isina tsvina.Asi kukwanisa kwesimbi isina tsvina haisi kungopikisa-ngura chete, izvi zvinogona kuonekwa kubva kune zita rayo rakazara: simbi isina tsvina uye acid-resistant.Simbi isina tsvina haingomiri kune oxidation, asiwo inodzivirira kune acid corrosion.
Masimbi ese asina tsvina anoshingirira kune oxidation, asi mhando uye chiyero chetsvina chiri mukati chakasiyana, uye kugona kurwisa kusvibiswa kweasidhi kwakasiyanawo (dzimwe nguva tinoona kuti pamusoro peimwe simbi isina tsvina ichiri ngura nekuti yakasvibiswa neasidhi) .Kuti tikwanise kusiyanisa acid corrosion resistance yeaya masimbi asina tsvina, vanhu vakatsanangura magiredhi akasiyana esimbi isina tsvina.
304 simbi isina tsvina uye 316 simbi isina tsvina
304 uye 316 ndiwo akajairika simbi isina simbi mamakisi muhupenyu hwedu.Isu tinogona kungozvinzwisisa se: iyo yakakura nhamba, iyo yakasimba iyo acid corrosion resistance yesimbi isina tsvina.
Kune simbi dzisina simbi dzisingadziviriri kune acid corrosion pane 304 simbi isina tsvina, asi idzo simbi dzisingagone kusangana nechikafu zvinodiwa.Zvokudya zvemazuva ose zvinogona kukanganisa simbi isina tsvina.Haina kunaka kune simbi isina tsvina, uye yakatonyanya kuipa kumuviri wemunhu.Semuenzaniso, simbi isina tsvina inoshandisa 201 simbi isina tsvina.
Kune zvakare simbi dzisina simbi dzinoshingirira kune acid corrosion kupfuura 316 simbi isina simbi, asi mutengo weaya masimbi akanyanya kukwirira.Zvinhu zvinogona kuvakanganisa zvakaoma kuona muhupenyu, saka isu hatifanire kuisa mari yakawandisa muchikamu ichi.
Chikafu giredhi Stainless simbi
Chekutanga pane zvese, muyero, hazvitaurwe kuti ndeipi giredhi resimbi isina tsvina igiredhi rekudya simbi isina tsvina.Mu "National Food Safety Standard Stainless Steel Products (GB 9684-2011)", nhevedzano yemararamiro ekupikisa zvinodiwa pakubata chikafu chesimbi isina tsvina inotsanangurwa.
Gare gare, mushure mekuenzanisa izvi zvinodiwa, vanhu vakaona kuti chiyero chiduku chesimbi isina tsvina inogona kuzadzisa izvi zvinodiwa ndeye 304 simbi isina tsvina.Saka pane tsumo inoti "304 Stainless steel is food grade Stainless steel".Zvisinei, munhu wose anofanira kukwanisa kunzwisisa pano kuti chirevo ichi hachisi chokwadi.Kana 304 ichigona kusangana nechikafu, ipapo 316 simbi isina tsvina, iyo inoshingirira kuasidhi uye ngura kupfuura 304 simbi isina tsvina, inongogona kuva-nani pane 316 simbi isina tsvina.Zvinogona kushandiswa sechisikigo pakubata chikafu.
Saka pane mubvunzo wekupedzisira: Ndosarudza yakachipa 304 yekushandisa pamba kana mutengo wepamusoro 316?
Kune simbi isina tsvina munzvimbo dzese, senge faucets, singi, racks, nezvimwewo, 304 simbi isina tsvina inokwana.Kune mamwe masimbi asina tsvina ari padyo nechikafu, kunyanya nemhando dzakasiyana dzekudya, senge tableware, makapu emvura, nezvimwe, unogona kusarudza 316 Stainless simbi-304 Stainless simbi yekubata nezvinogadzirwa nemukaka, carbonated drinks, nezvimwe. icharamba iine ngura.
