1. Okuqukethwe Okuhlukile Kwezakhi Zamakhemikhali Phakathi Kwensimbi Engagqwali ye-AISI 304 Nensimbi Engagqwali engu-201
● 1.1 Amapuleti ensimbi engagqwali ayevame ukusetshenziswa ahlukaniswe ngezinhlobo ezimbili: 201 kanye no-304. Eqinisweni, izingxenye zihlukile. Insimbi engagqwali engu-201 iqukethe i-chromium engu-15% kanye ne-nickel engu-5%. Insimbi engagqwali engu-201 ithatha indawo yensimbi engu-304. Futhi insimbi engagqwali engu-304 iqukethe i-chromium engu-18% kanye ne-nickel engu-9% ngokwezinga elijwayelekile. Uma kuqhathaniswa, okuqukethwe yi-nickel kanye ne-chromium ku-304 kuphakeme kunalokho okwango-201, ngakho-ke ukumelana nokugqwala okungu-304 kungcono kakhulu kunalokho okwango-201. Kodwa-ke, ngoba i-304 iqukethe i-nickel kanye ne-chromium eningi kunaleyo ka-201, intengo ye-304 ibiza kakhulu kuneka-201.
● 1.2 Insimbi engagqwali engu-201 iqukethe i-manganese eningi, kodwa engu-304 iqukethe encane; Kusukela kumbala wobuso bezinto ezibonakalayo, insimbi engagqwali engu-201 iqukethe i-manganese eningi ukuze umbala wobuso ube mnyama kuno-304, u-304 kufanele ukhanye futhi ube mhlophe, kodwa lokhu akulula ukuwahlukanisa ngeso lenyama.
● 1.3 Ngenxa yokuqukethwe okuhlukile kwe-nickel element, ukumelana nokugqwala kuka-201 akukuhle njengokwa-304; Ngaphezu kwalokho, okuqukethwe kwekhabhoni kuka-201 kuphakeme kunokwa-304, ngakho-ke u-201 uqinile futhi uyaphuka kalula kuno-304. U-304 unokuqina okungcono: Uma usebenzisa ummese oqinile wokusika ebusweni buka-201, ngokuvamile kuzoba nokuklwebheka okusobala kakhulu, nokho ukuklwebheka ku-304 ngeke kubonakale kakhulu.
2. Ukwakhiwa Kwensimbi Engagqwali kanye Nezici Zokusetshenziswa
● Insimbi engagqwali engu-201, inokumelana okuthile kwe-asidi, ukusebenza kokumelana ne-alkali, ukuminyana okuphezulu, ukupholisha ngaphandle kwamabhamuza, akukho mgodi wephini kanye nezinye izici, ukukhiqizwa kwezinhlobo ezahlukene zamawashi, izinto zekhwalithi yesisekelo sewashi. Isetshenziswa kakhulu ukwenza ipayipi lokuhlobisa, ipayipi lezimboni, kanye neminye imikhiqizo yokwelula engajulile.
● Uhla lokusetshenziswa kwensimbi engagqwali engu-304: Insimbi engagqwali engu-304 iyinsimbi engagqwali ye-chromium nickel esetshenziswa kakhulu, njengohlobo lwensimbi esetshenziswa kabanzi, inokumelana okuhle nokugqwala, ukumelana nokushisa, amandla okushisa aphansi kanye nezakhiwo zemishini. Ukumelana nokugqwala emkhathini, uma kuyindawo yezimboni noma indawo engcoliswe kakhulu, idinga ukuhlanzwa ngokushesha ukuze kugwenywe ukugqwala. Insimbi engagqwali engu-304 ukuze kuqashelwe kazwelonke insimbi engagqwali yezinga lokudla.
● Uma kunqunywa uhlobo lwensimbi engagqwali okufanele isetshenziswe, izindinganiso zobuhle ezidingekayo, ukugqwala komkhathi wendawo kanye nohlelo lokuhlanza okufanele lusetshenziswe kuyacatshangelwa.
● Insimbi engagqwali engu-304 iyasebenza kakhulu endaweni eyomile yangaphakathi. Kodwa-ke, ezindaweni zasemakhaya nasemadolobheni ukuze kugcinwe ukubukeka kwayo ngaphandle, kudingeka ukuhlanza njalo. Ezindaweni zezimboni ezingcoliswe kakhulu nasezindaweni ezisogwini, izindawo zingangcola kakhulu futhi zigqwale. Kodwa ukuze uthole umphumela wobuhle endaweni engaphandle, kubalulekile ukusebenzisa insimbi engagqwali equkethe i-nickel.
● Ngakho-ke, insimbi engagqwali engu-304 isetshenziswa kabanzi odongeni lwekhethini, odongeni oluseceleni, ophahleni nakwezinye izinjongo zokwakha, kodwa esimweni esinzima sezimboni noma solwandle, kungcono ukusebenzisa insimbi engagqwali engu-304. Ngaphezu kwalokho, insimbi engagqwali engu-304 inezici zokusebenza kahle kokucubungula kanye nokuqina okuphezulu. Ngenxa yalokhu, i-304 isetshenziswa kabanzi embonini, embonini yokuhlobisa ifenisha kanye nasembonini yezokwelapha yokudla.
Amakhoyili/amashidi ensimbi engagqwali kaJINDALAI anezindawo ezahlukahlukene, imibala, osayizi, kanye nezimo ukuze kuhlangatshezwane nezidingo zakho ngezikhathi ezahlukene. Samukela futhi iphethini, usayizi, ukuma, umbala, kanye nokwelashwa kwendawo ngokwezifiso. Thumela umbuzo wakho futhi sizojabula ukubonisana nawe ngobuchwepheshe.
