Sisebenzisa amakhukhi ukuthuthukisa ulwazi lwakho.Ngokuqhubeka nokuphequlula leli sayithi, uyavumelana nokusebenzisa kwethu amakhukhi.Ulwazi olwengeziwe.
Insimbi engagqwali ingaphezu nje kwensimbi ekwazi ukumelana nokugqwala.Insimbi engagqwali ivame ukukhethwa njengento eguquguqukayo yezinhlelo eziningi zokusebenza ngenxa yamandla ayo, ukumelana nokugqwala kanye nekhono lokuzivumelanisa nezimo ezithile.
304 304L 316 316L abahlinzeki bepuleti lensimbi engenasici e-china
I-Stainless Steel 304 iyibanga lensimbi engagqwali elisetshenziswa kakhulu.Insimbi engagqwali ye-chromium-nickel austenitic enokuqukethwe kwekhabhoni ephansi kanye ne-chromium ne-nickel ephakeme ngandlela thize kunezinhlobo ze-AISI ezingu-301 no-302. Ibanga lama-304 lidonsa kakhulu uma lisesimweni sokuhosha.Inezici ezinhle zokushisa eziphakeme kanye nokuqina okuhle emazingeni okushisa aphansi.Ifaneleka kahle ekushiseleni futhi lapho umkhiqizo oqediwe kufanele umelane nezinhlobo ezimbi kakhulu zokugqwala.

Lokhu akusebenzi nje kuphela ekuhlanganiseni kwamakhemikhali ahlukene okwenza insimbi engagqwali, kodwa nasezindaweni ezihlukene zokumbozwa kanye nokwelapha okungaphezulu okusetshenziswa kuye ngokuthi kuhloswe ukuphela kokusetshenziswa komkhiqizo.
I-Grade 2B ingenye yezindlela zokwelapha ezisetshenziswa kakhulu embonini yensimbi engagqwali.I-semi-reflective, ibushelelezi futhi ifana, nakuba ingesona isibuko.Ukulungiswa kwendawo kuyisinyathelo sokugcina kule nqubo: ishidi lensimbi lakhiwa kuqala ngokucindezela phakathi kwamaroli lapho kuphuma isithando somlilo.Ibe isithanjiswa ngokufakwa kwe-anneal bese iphinda idluliswe kuma-rolls.
Ukuze kukhishwe ukungcola okungaphezulu, indawo engaphezulu ifakwe i-asidi futhi idluliswe phakathi kwamarola wokupholisha izikhathi eziningana ukuze kuzuzwe ukujiya okufunayo.Kwakuyilokhu kudlula kokugcina okuholele ekuphothulweni kwe-2B.
I-2B ukuphela okujwayelekile kumamaki ajwayelekile ensimbi engagqwali, okuhlanganisa u-201, 304, 304 L, kanye no-316 L. Ukuduma kokupholishwa kwe-2B, ngaphezu kokuba ukonga futhi ukumelana nokugqwala, kutholakala kalula ekupholishweni ngesondo lendwangu futhi inhlanganisela.
Imvamisa, insimbi yokuqeda engu-2B isetshenziswa ekucubunguleni ukudla, okokusebenza kwebhikawozi, izitsha, amathangi okugcina, nezinto zokusebenza zemithi futhi ihlangabezana nezindinganiso ze-USDA zalezi zimboni.
Le ndlela ayamukelekile uma umkhiqizo wokugcina uyisixazululo esijovwayo noma esine-otic.Lokhu kungenxa yokuthi izikhala noma amaphakethe angakha endaweni yensimbi.Lezi zikhala zingabamba ukungcola ngaphansi kwendawo epholishiwe noma ensimbi.Ekugcineni, lezi zinto zangaphandle zingabaleka futhi zingcolise umkhiqizo.I-Surface electropolishing iyindlela ekahle nenconyiwe yokuthuthukisa ukushelela kwendawo yezinhlelo ezinjalo.
I-Electropolishing isebenza ngokusebenzisa amakhemikhali nogesi ukuze bushelelezi izindawo eziphakeme endaweni yensimbi engagqwali.Ngisho nefekthri esetshenziswa I-Smooth 2B Coating, indawo yangempela yensimbi engenasici ngeke ibonakale ibushelelezi uma ikhuliswa.
I-Average Roughness (Ra) isetshenziselwa ukubhekisela kubushelelezi bendawo yensimbi futhi iyisiqhathaniso somehluko omaphakathi phakathi kwamaphoyinti aphansi naphezulu endaweni ngokuhamba kwesikhathi.
Ngokuvamile, insimbi engagqwali entsha yasembonini enokuphela okungu-2B inenani lika-Ra ebangeni elingu-0.3 micron (0.0003 mm) kuya ku-micron ongu-1 (0.001 mm) kuye ngokujiya kwayo (ubukhulu).I-Surface Ra ingancishiswa ibe yi-4-32 micro inches by electropolishing efanele, kuye ngezici zensimbi.
Ukuqedwa kwekilasi 2B kufinyelelwa ngokucindezela impahla ngamarola amabili.Abanye opharetha badinga ukulungiswa kwe-trim ngemva kokulungiswa noma ukulungiswa komkhumbi noma ezinye izinto zokusebenza.
Nakuba indawo engaphezulu etholwe ngomshini noma nge-electropolishing ingakwazi ukuphinda ikhiqizeke kalula, ingaba seduze kakhulu, ikakhulukazi ngokuphathelene namanani ka-Ra.Njengomphumela wokwelashwa okufanele kwe-electropolishing, ukusebenza okungcono nakakhulu mayelana nokucubungula impahla kungafinyelelwa kunokwelashwa kwasekuqaleni okungakaqedwa kwe-2B.
Ngakho-ke, isilinganiso se-2B singathathwa njengesiqalo esihle.Izingubo ze-2B zinezinzuzo ezaziwayo futhi ziyonga.Ingathuthukiswa ngokuqhubekayo nge-electropolishing ukuze iphele kahle, amazinga aphezulu kanye nohlu lwezinzuzo zesikhathi eside.
Lolu lwazi luqinisekisiwe futhi lwashintshwa ezintweni ezinikezwe yi-Astro Pak Corporation.
