Muhupenyu hwezuva nezuva, vanhu vazhinji vanotenda kuti simbi isina tsvina haisi-magnetic uye vanoshandisa magineti kuti vaone.Nekudaro, nzira iyi haina kunaka mune zvesainzi.Chekutanga, zinc alloys nemhangura alloys anogona kutevedzera chitarisiko uye kushaya magineti, zvichitungamira kune kukanganisa kutenda kuti isimbi isina tsvina.Kunyangwe iyo inonyanya kushandiswa simbi isina giredhi, 304, inogona kuratidza akasiyana madhigirii emagnetism mushure mekushanda kunotonhora.Naizvozvo, kuvimba chete nemagineti kuti uone chokwadi chesimbi isina simbi haina kuvimbika.
Saka, chii chinokonzera magineti musimbi isina tsvina?
Zvinoenderana nekudzidza kwefizikisi yezvinhu, iyo magnetism yesimbi inotorwa kubva kune erekitironi spin chimiro.Electron spin is a quantum mechanical property inogona kuva "kumusoro" kana "pasi."Mumidziyo yeferromagnetic, maerekitironi anorongeka otomatiki munzira imwe chete, nepo ari mumidziyo yeantiferromagnetic, mamwe maerekitironi anotevera mapatani akajairwa, uye maerekitironi ari pedyo ane maspins akapesana kana kuti antiparallel.Zvisineyi, maerekitironi ari mumatriangular lattices, ose anofanira kutenderera akananga kudivi rimwe mukati megonyonhatu imwe neimwe, zvichiita kuti pashaikwe mambure spina structure.
Kazhinji, austenitic Stainless simbi (inomiririrwa ne304) haisi-magnetic asi inogona kuratidza isina simba magineti.Ferritic (kunyanya 430, 409L, 439, uye 445NF, pakati pevamwe) uye martensitic (inomiririrwa ne410) simbi dzisina tsvina dzinowanzoita magineti.Kana magiredhi esimbi asina simbi se304 akaiswa seasiri magineti, zvinoreva kuti magineti yavo inowira pasi pechimwe chikumbaridzo;zvisinei, akawanda Stainless simbi mamakisi anoratidza imwe dhigirii remagineti.Pamusoro pezvo, sezvambotaurwa, austenite haisi-magineti kana isina simba remagineti, nepo ferrite nemartensite zvine magineti.Kurapwa kusina kunaka kwekupisa kana kupatsanurwa kwemukati panguva yekunyunguduka kunogona kukonzera kuvepo kwezvishoma zvemartensitic kana ferritic zvimiro mukati me304 simbi isina tsvina, zvichitungamira kune isina simba magineti.
Uyezve, chimiro che304 simbi isina tsvina inogona kushanduka kuita martensite mushure mekushanda kunotonhora, uye iyo inonyanya kukosha deformation, iyo yakawanda martensite mafomu, zvichikonzera kusimba kwemagineti.Kubvisa zvachose magineti mu304 simbi isina tsvina, yakakwirira-tembiricha mhinduro kurapwa inogona kuitwa kudzoreredza yakagadzikana austenite chimiro.
Muchidimbu, iyo magineti yechinhu inotemerwa nekugara kwemamorekuru kuronga uye kurongeka kwema electron spins.Inoonekwa sechinhu chenyama yezvinhu.Kudzivirirwa kwekuora kwechinhu, kune rumwe rutivi, kunotemerwa nemakemikari ayo uye inozvimiririra kune yayo magineti.
Tinovimba kuti tsananguro pfupi iyi yabatsira.Kana iwe uine chero mimwe mibvunzo nezve simbi isina tsvina, ndapota inzwa wakasununguka kubvunza EST Chemical's vatengi sevhisi kana kusiya meseji, uye isu tichafara kukubatsira.
