Kawirikawiri, VJ Piping imapangidwa ndi chitsulo chosapanga dzimbiri kuphatikizapo 304, 304L, 316 ndi 316Letc. Apa tikufotokozera mwachidule makhalidwe a zipangizo zosiyanasiyana zosapanga dzimbiri.
SS304
Chitoliro cha chitsulo chosapanga dzimbiri cha 304 chimapangidwa motsatira muyezo wa American ASTM wa mtundu wa chitsulo chosapanga dzimbiri.
Chitoliro chachitsulo chosapanga dzimbiri cha 304 ndi chofanana ndi chitoliro chathu chachitsulo chosapanga dzimbiri cha 0Cr19Ni9 (OCr18Ni9).
Chubu chachitsulo chosapanga dzimbiri cha 304 monga chitsulo chosapanga dzimbiri chimagwiritsidwa ntchito kwambiri mu zida za chakudya, zida zamankhwala wamba, komanso mafakitale a mphamvu za atomiki.
Chitoliro chachitsulo chosapanga dzimbiri cha 304 ndi chitoliro chachitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito padziko lonse lapansi, chimagwiritsidwa ntchito kwambiri popanga zida ndi zida zabwino kwambiri (zolimbanirana ndi dzimbiri komanso kupangika bwino).
Chitoliro cha chitsulo chosapanga dzimbiri cha 304 ndicho chitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito kwambiri popanga chakudya, zida zamankhwala, mphamvu ya nyukiliya, ndi zina zotero.
304 chubu chachitsulo chosapanga dzimbiri specifications C, Si, Mn, P, S, Cr, Ni, (Nickel), Mo.
Kusiyana kwa Magwiridwe a Ntchito a Chitsulo Chosapanga Dzimbiri 304 ndi 304L
304L imalimbana ndi dzimbiri kwambiri, 304L ili ndi kaboni wochepa, 304 ndi chitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito padziko lonse lapansi, ndipo chimagwiritsidwa ntchito kwambiri popanga zida ndi zida zomwe zimafuna magwiridwe antchito abwino (kukana dzimbiri ndi kupangika bwino). 304L ndi mtundu wa chitsulo chosapanga dzimbiri cha 304 chokhala ndi kaboni wochepa ndipo chimagwiritsidwa ntchito powotcherera. Kuchepa kwa kaboni kumachepetsa mvula ya carbides m'dera lomwe lakhudzidwa ndi kutentha pafupi ndi chowotcherera, zomwe zingayambitse dzimbiri la pakati pa granular (kuwotcherera) mu chitsulo chosapanga dzimbiri m'malo ena.
304 imagwiritsidwa ntchito kwambiri, ndi kukana dzimbiri bwino, kukana kutentha, mphamvu yochepa kutentha komanso mphamvu zamakanika; Kukonza bwino kutentha, monga kuponda ndi kupindika, popanda kutentha, kuuma popanda vuto la kutentha (popanda maginito, pogwiritsa ntchito kutentha -196℃ -800℃).
304L imapirira dzimbiri bwino kwambiri pambuyo powotcherera kapena kuchepetsa kupsinjika: imatha kusunga dzimbiri bwino ngakhale popanda kutentha, kutentha kogwira ntchito -196℃ -800℃.
SS316
Chitsulo chosapanga dzimbiri cha 316 chilinso ndi mphamvu zabwino zokokoloka kwa chloride, kotero chimagwiritsidwa ntchito kwambiri m'malo okhala ndi madzi a m'nyanja.
Fakitale ya chubu chachitsulo chosapanga dzimbiri chosagwira dzimbiri
Kukana dzimbiri kuli bwino kuposa chitsulo chosapanga dzimbiri cha 304, pamene zamkati ndi mapepala zimapanga dzimbiri.
Ndipo chitsulo chosapanga dzimbiri cha 316 chimalimbananso ndi mpweya wa m'nyanja komanso wa mafakitale. Kukana kutentha pa madigiri 1600 pansi pa kugwiritsidwa ntchito kosalekeza komanso pa madigiri 1700 pansi pa kugwiritsidwa ntchito kosalekeza, chitsulo chosapanga dzimbiri cha 316 chili ndi kukana kwabwino kwa okosijeni.
Pa kutentha kwa madigiri 800-1575, ndibwino kuti musagwiritse ntchito chitsulo chosapanga dzimbiri cha 316 nthawi zonse, koma pa kutentha komwe sikupitirira kugwiritsa ntchito chitsulo chosapanga dzimbiri cha 316 nthawi zonse, chitsulo chosapanga dzimbiri chimakhala ndi kukana kutentha bwino.
Kukana kwa mpweya wa carbide kwa chitsulo chosapanga dzimbiri cha 316 kuli bwino kuposa kwa chitsulo chosapanga dzimbiri cha 316 ndipo kungagwiritsidwe ntchito pa kutentha komwe kwatchulidwa pamwambapa.
Chitsulo chosapanga dzimbiri cha 316 chili ndi ntchito yabwino yolumikiza. Chikhoza kulumikizidwa pogwiritsa ntchito njira zonse zolumikizira. Kulumikiza kungagwiritsidwe ntchito pogwiritsa ntchito ndodo ya 316Cb, 316L kapena 309CB yodzaza chitsulo chosapanga dzimbiri kapena kulumikiza kwa electrode. Kuti mupeze kukana kwabwino kwambiri kwa dzimbiri, gawo lolumikizira la chitsulo chosapanga dzimbiri cha 316 liyenera kulumikizidwa pambuyo polumikiza. Kulumikiza pambuyo polumikiza sikofunikira ngati chitsulo chosapanga dzimbiri cha 316L chikugwiritsidwa ntchito.
Ntchito zomwe zimagwiritsidwa ntchito nthawi zambiri: zida zosinthira kutentha, zida zopaka utoto, zida zopangira mafilimu, mapaipi, ndi zipangizo zakunja kwa nyumba za m'mizinda m'madera a m'mphepete mwa nyanja.
Chitsulo Chosapanga Dzimbiri Choletsa Mabakiteriya
Ndi chitukuko cha zachuma, chitsulo chosapanga dzimbiri mumakampani azakudya, ntchito zophikira chakudya, komanso kugwiritsa ntchito moyo wabanja kukuchulukirachulukira, tikukhulupirira kuti kuwonjezera pa ziwiya zapakhomo ndi mbale zapakhomo zachitsulo chosapanga dzimbiri, zinthu zatsopano zimakhala zowala komanso zoyera, komanso zimakhala ndi ntchito yabwino kwambiri yoteteza ku matenda a bakiteriya, komanso yoyeretsa.
Monga tonse tikudziwira, zitsulo zina, monga siliva, mkuwa, bismuth ndi zina zotero zimakhala ndi mphamvu yowononga mabakiteriya, yomwe imatchedwa chitsulo chosapanga dzimbiri choletsa mabakiteriya, imakhala mu chitsulo chosapanga dzimbiri kuti iwonjezere kuchuluka koyenera kwa zinthu zomwe zimakhala ndi mphamvu yolimbana ndi mabakiteriya (monga mkuwa, siliva), kupanga chitsulo pambuyo pa chithandizo cha kutentha cha antibacterial, ndi magwiridwe antchito okhazikika komanso magwiridwe antchito abwino othana ndi mabakiteriya.
Mkuwa ndi chinthu chofunikira kwambiri pa mankhwala ophera mabakiteriya, kuchuluka komwe kungafunike kuwonjezera sikuyenera kungoganizira za mphamvu ya mankhwala ophera mabakiteriya, komanso kuonetsetsa kuti chitsulocho chili ndi mphamvu zabwino komanso zokhazikika. Kuchuluka kwa mkuwa kumasiyana malinga ndi mitundu ya chitsulo. Kapangidwe ka mankhwala a chitsulo chosapanga dzimbiri chophera mabakiteriya chopangidwa ndi Japanese Nissin Steel kakuwonetsedwa mu Table 10. 1.5% ya mkuwa imawonjezedwa ku chitsulo cha ferritic, 3% ku chitsulo cha martensitic ndi 3.8% ku chitsulo cha austenitic.
