Kushandiswa kwakawanda kwezvigadzirwa zvesimbi isina tsvina ndeyekuchinja mukicheni, yakanaka, yakasimba, iri nyore kuchenesa, uye inoshandura zvakananga ruvara uye kunzwa kwekicheni.Somugumisiro, nzvimbo yekuona yekicheni yakagadziridzwa zvikuru, uye haisisiri yakasviba uye yakanyorova, uye yakasviba.
Zvisinei, kune marudzi akawanda esimbi isina tsvina, uye musiyano pakati pawo hausi muduku.Dzimwe nguva, mibvunzo yekuchengetedza inonzwika, uye idambudziko kusarudza.
Kunyanya kana zvasvika kune mapoto, tableware nemimwe midziyo inotakura zvakananga chikafu, zvinyorwa zvinova zvakanyanya.Nzira yekuvasiyanisa sei?
Chii chinonzi Stainless steel?
Chinhu chakakosha chesimbi isina tsvina chinotemerwa nezvinhu zviviri, zvinova chromium uye nickel.Pasina chromium, haisi simbi isina tsvina, uye chiyero che nickel chinotarisa kukosha kwesimbi isina tsvina.
Simbi isina tsvina inogona kuchengetedza kupenya mumhepo uye haina ngura nekuti ine imwe chiyero chechromium alloy element (kwete pasi pe10.5%), iyo inogona kugadzira yakasimba oxide firimu pamusoro pesimbi isinganyungudika mune mamwe midhiya.
Mushure mekuwedzera nickel, kushanda kwesimbi isina tsvina kunowedzera kuvandudzwa, uye ine kugadzikana kwakanaka kwekemikari mumhepo, mvura uye muutsi, uye inewo kugadzikana kwakakwana mumhinduro dzakawanda dzeaqueous yeasidhi, alkali uye munyu, kunyangwe pakupisa kwakanyanya kana Mu. yakadzika tembiricha nharaunda, inogona kuramba ichichengetedza corrosion resistance.
Zvinoenderana neiyo microstructure, simbi isina tsvina yakakamurwa kuita martensitic, austenitic, ferritic uye duplex simbi isina tsvina.Austenite ine yakanaka plasticity, yakaderera simba, kumwe kuoma, nyore kugadzirisa uye kugadzira, uye isina ferromagnetic zvivakwa.
Austenitic simbi isina tsvina yakabuda muGermany muna 1913, uye yakagara ichiita basa rinokosha musimbi isina tsvina.Kugadzirwa kwayo uye kushandiswa kunotora chikamu che70% yehuwandu hwekugadzirwa uye kushandiswa kwesimbi isina tsvina.Kune zvakare mamakisi mazhinji esimbi, saka mazhinji esimbi asina tsvina aunoona mazuva ese ndeye austenitic simbi isina tsvina.
Iyo inozivikanwa kwazvo 304 simbi inonzi austenitic Stainless simbi.Yakapfuura Chinese yenyika chiyero ndeye 0Cr19Ni9 (0Cr18Ni9), zvinoreva kuti ine 19% yeCr (chromium) uye 9% yeNi (nickel).0 zvinoreva kabhoni <= 0.07%.
Kubatsira kwekumiririra kweChinese yenyika chiyero ndechekuti zvinhu zviri musimbi isina tsvina zvinojeka pakungotarisa.Kana ari 304, 301, 202, nezvimwewo, ndiwo mazita eUnited States neJapan, asi iye zvino munhu wese anoshandiswa kune iri zita.
Patented trademark Cromargan 18-10 yeWMF pan Stainless simbi
Tinowanzoona midziyo yekubikira yakanyorwa mazwi 18-10 uye 18-8.Iyi mhando yenzira yekumaka inoratidza chikamu chechromium uye nickel musimbi isina tsvina.Chiyero che nickel chakakwira uye hunhu hwakanyanya kugadzikana.
18-8 (nickel isiri pasi pe8) inoenderana ne304 simbi.18-10 (nickel isiri pasi pe10) inoenderana ne316 simbi (0Cr17Ni12Mo2), iyo inonzi inonzi medical stainless steel.
304 simbi haisi yeumbozha, asi haina kudhura
Mafungiro ekuti austenitic 304 simbi isina tsvina yakakwira-magumo imhaka yaXiaomi, uyo akarongedza zvinodiwa zvemazuva ese kwemakumi emakore muzvigadzirwa zvepamusoro-soro.
Mukicheni yemazuva ese nharaunda, iyo corrosion kuramba uye kuchengetedzwa kwe304 zvakakwana zvakakwana.Iyo yakanyanya kukwirisa 316 (0Cr17Ni12Mo2) inoshandiswa mumakemikari, ekurapa uye mamwe minda, ine yakanyanya kugadzikana makemikari zvimiro uye zvakanyanya kuomarara kuramba.
Austenitic 304 simbi ine simba rakaderera uye inowanzo shandiswa mumidziyo yekubikira, nepo mapanga anoshandisa zvakaomarara martensitic simbi isina tsvina (420, 440), iyo ine kushoma ngura.
Munguva yakapfuura, zvaifungidzirwa kuti zvinogona kukonzera dambudziko, kunyanya 201, 202 uye mamwe manganese ane simbi isina tsvina.201 uye 202 simbi isina tsvina ndiyo yakaderera-yekupedzisira zvigadzirwa musimbi isina tsvina, uye 201 uye 202 inogadzirwa kutsiva chikamu che304 simbi isina tsvina.Chikonzero ndechekuti kana ichienzaniswa neye nickel, manganese yakachipa zvakanyanya.Cr-nickel-manganese austenitic simbi dzisina tsvina dzakadai se201 uye 202 inenge hafu yemutengo we304 simbi.
Zvechokwadi, 304 simbi pachayo haina kudhura sezvairi, inenge 6 kana 7 yuan pakateti, uye 316 simbi uye 11 yuan pakateti.Ehe, mutengo wezvinhu kazhinji hausi chinhu chakakosha pamutengo wekupedzisira wechigadzirwa.Zvokubikira kunze kwesimbi isina tsvina zvinodhura, kwete zvese nekuda kwezvinhu zvakanaka.
Mutengo weyuniti patani yesimbi yekugadzira simbi inongori 1/25 chete yechromium uye 1/50 yeiyo nickel.Pakati pemitengo kunze kweiyo annealing process, iyo mbishi mutengo we austenitic Stainless simbi zviri pachena kuti wakakwira zvakanyanya kupfuura iyo yemartensite uye iron isina nickel.Simbi yakasimba isina tsvina.304 simbi yakajairwa asi haina kudhura, zvirinani maererano nekukosha kwesimbi mbishi.
Maererano nemitemo yenyika, haugone kuziva kuti ndeupi muenzaniso usingashandisi mukicheni
Iyo yekare yenyika standard GB9684-1988 inotaura kuti chikafu-giredhi simbi isina tsvina yakakamurwa kuita midziyo uye tableware., Martensitic simbi isina tsvina (0Cr13, 1Cr13, 2Cr13, 3Cr13) inofanira kushandiswa."
Zvakapusa, tarisa imwe simbi modhi uye unoziva kuti ndezvipi zvinhu zvinogona kushandiswa mukugadzira chikafu, midziyo, kucheka.Zviripachena, chiyero chenyika panguva iyoyo chairatidza zvakananga 304 simbi sechikafu-giredhi simbi isina tsvina.
Nekudaro, chiyero chenyika chakazoburitswa gare gare - National Chikafu Chengetedzo Chiyero cheStainless Steel Zvigadzirwa GB 9684-2011 haicharondedzere mamodheru, uye vanhu havachakwanisa kutonga zvakananga kuti chii chikafu giredhi kubva kumuenzaniso.Yakangoti in general:
"Tableware midziyo, kugadzirwa kwechikafu uye maturusi ekushanda, uye zvikamu zvikuru zvemidziyo zvinofanirwa kugadzirwa nesimbi isina tsvina inoenderana nemitemo yenyika, senge austenitic stainless steel, austenitic ferritic stainless steel, uye ferritic stainless steel;tableware nemichina yekugadzira chikafu Martensitic Stainless simbi inogona zvakare kushandiswa kune iyo huru yemidziyo, senge yekuchera uye yekukuya maturusi."
Mune chiyero chitsva chenyika, kunaya kwezvikamu zvesimbi kunoshandiswa kuona kana mwero wasangana muzviratidzo zvemuviri nemakemikari.
Izvi zvinoreva kuti kuvanhuwo zvavo, zvakaoma chaizvo kusiyanisa kuti chii chiri chikafu-giredhi simbi isina tsvina, sokunge chero chinhu chinogona kuitwa, chero bedzi pasina dambudziko.
Handizive, ndosarudza sei?
Kuchengetedza kunetseka kwesimbi isina tsvina ndeye manganese.Kana kudyiwa kwesimbi dzinorema senge manganese kwakapfuura imwe mwero, pachave nekumwe kukuvadzwa kuhurongwa hwetsinga, sekurasikirwa nendangariro uye kushomeka kwesimba.
Saka ichakonzera chepfu nekuda kwekushandiswa kwezvigadzirwa zvesimbi zvisina tsvina se201 uye 202?Mhinduro haina kujeka.
Chekutanga kushaikwa kwehumbowo hwenyaya muhupenyu chaihwo.Mukuwedzera, muchirevo, hapana migumisiro inogutsa.
Pane mutsara wekirasi mune idzi nhaurirano: kutaura nezve toxicity pasina dosi ihooliganism.
Kufanana nemamwe maelementi akawanda, munhu haaparadzaniswi nemanganese, asi kana akasveta zvakanyanya, anokonzera tsaona.Kune vanhu vakuru, "chiyero chakakwana" chemanganese ndeye 2-3 mg pazuva muUnited States uye 3.5 mg muChina.Pamuganho wepamusoro, zviyero zvakatarwa neChina neUnited States zvakatenderedza 10 mg pazuva.Sekureva kwenhau, manganese ekudya kwevagari vekuChina angangoita 6.8 mg pazuva, uye zvinonziwo manganese yakanyungudutswa kubva ku201 steel tableware haina basa uye haitombo shandura huwandu hwevanhu hwemanganese.
Madhasi aya akajairwa anowanikwa sei, achachinja mune ramangwana, uye madyiro uye kunaya kwemvura kunopihwa nemishumo yenhau kuchave kukahadzika.Nzira yekuita sarudzo panguva ino?

Nzira yekuziva sei idzi simbi dzisina tsvina?
MaGerman emhando yepamusoro akadai saFissler, WMF uye Zwilling anowanzo shandisa 316 (18-10), uye zvigadzirwa zvepamusoro hazvina kujeka.
MaJapan anoshandisa 304, uye anowanzo taura zvinongedzo zvavo zvakananga.
Kune zvigadzirwa izvo zvinyorwa zvisingavimbiki zvakanyanya, nzira yakavimbika ndeyekutumira kune laboratori, asi vatengi vazhinji havana mamiriro aya.Vamwe manetizens vanofunga kuti kushandisa magineti kuona magineti zvimiro inzira, uye kuti austenitic 304 simbi haina magineti, nepo ferrite Muviri uye martensitic simbi zvine magineti, asi chokwadi austenitic 304 simbi haisi isiri-magnetic, asi zvishoma magineti.
Austenitic simbi inonamira shoma shoma yemartensite panguva yekutonhora kwekushanda, uye ine mamwe magineti emhando yepamusoro, inokotama uye yakachekwa pamusoro, uye 201 simbi isina tsvina zvakare ine magineti zvishoma, saka haina kuvimbika kushandisa magineti.
