Sei 304 simbi isina tsvina ichishandiswa mukicheni?

Kushandiswa kwakawanda kwezvigadzirwa zvesimbi isina tsvina ndeyekuchinja mukicheni.Iwo akanaka, anogara, uye ari nyore kuchenesa.Vanoshandura zvakananga ruvara uye kubata kwekicheni.Somugumisiro, nzvimbo yekuona yekicheni yakagadziridzwa zvikuru.
Zvisinei, kune marudzi akawanda esimbi isina tsvina, uye musiyano pakati pawo hausi muduku.Dzimwe nguva mibvunzo yekuchengetedza inogona kunzwika, uye idambudziko kuisarudza.

Kunyanya kana zvasvika kune mapoto, tableware nemimwe midziyo inotakura zvakananga chikafu, zvigadzirwa zvinova zvakanyanya.Nzira yekuvasiyanisa sei?Sanjiangfood (ID: sanjiangfood) inotenda kuti munhu wese anofanira kushandisa zvese zviri mukicheni zvakajeka.
Chii chinonzi Stainless steel?
Chinhu chakakosha chesimbi isina tsvina chinotemerwa nezvinhu zviviri, zvinova chromium uye nickel.Pasina chromium, hapana simbi isina tsvina, uye chiyero chenickel chinotarisa kukosha kwesimbi isina tsvina.

Simbi isina tsvina inogona kuchengetedza kupenya kwayo mumhepo uye haina ngura nekuti ine imwe chiyero chechromium alloy element (kwete isingasviki 10.5%), iyo inogona kugadzira yakasimba oxide firimu pamusoro pesimbi isinganyunguke mune mamwe midhiya. .

Mushure mokunge nickel yawedzerwa, kushanda kwesimbi isina tsvina kunowedzera kuvandudzwa.Iine kugadzikana kwakanaka kwemakemikari mumhepo, mvura, uye chiutsi, uye ine kugadzikana kwakakwana mumhando dzakawanda dzeasidhi, alkali, uye munyu ane aqueous solutions, kunyangwe pakupisa kwakanyanya kana Munzvimbo yakaderera tembiricha, inogona kuramba ichichengetedza zvakanakira ngura. 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, kugadzirisa nyore uye kugadzira, uye haina ferromagnetism.

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 akawanda esimbi, saka mazhinji esimbi asina tsvina aunoona zuva nezuva ndeye austenitic simbi isina tsvina.

Iyo inozivikanwa kwazvo 304 simbi inonzi austenitic Stainless simbi.Yakapfuura Chinese yenyika chiyero yaive 0Cr19Ni9 (0Cr18Ni9), zvinoreva kuti ine 19% Cr (chromium) uye 9% Ni (nickel).0 zvinoreva carbon content<=0.07%.

Chakanakira cheChinese yenyika chiyero ndechekuti zvinhu zviri musimbi isina tsvina zvinojeka pakungotarisa.Kana iri 304, 301, 202 uye zvichingodaro, ndiro zita reUnited States neJapan, asi ikozvino munhu wese ajaira zita iri.color2
