Muva nje, kukhishwe indinganiso kazwelonke ye-GB/T20878-2024 ethi “Stainless Steel Grades and Chemical Compositions”, ehlelwe yi-Metallurgical Industry Information Standards Research Institute futhi ehlanganyelwe yi-Fujian Qingtuo Special Steel Technology Research Co., Ltd. kanye namanye amayunithi, futhi izoqala ukusebenza ngomhlaka-1 kuNhlolanja 2025. Ngemva kweminyaka ecishe ibe yisithupha yemizamo engapheli, iQingtuo Group yathuthukisa ngokuzimela uchungechunge lwe-QN lwensimbi engagqwali oluqukethe i-nitrogen oluqiniswe kakhulu, okuhlanganisa i-S35250 (QN1701), i-S25230 (QN1801), i-S35657 (QN1803), i-S35656 (QN1804), i-S35388 (Imikhiqizo enamazinga ahlukene okumelana nokugqwala njenge-QF1804), i-S35706 (QN2008), i-S35886 (QN1906) kanye ne-S35887 (QN2109) ifakiwe kuleli zinga, okuthuthukisa isakhiwo sezinhlobo zensimbi engagqwali futhi kuhlinzeka ngamandla aphezulu, alula, kanye nokumelana nokugqwala okuphezulu emkhakheni wezakhiwo ezithwala imithwalo. Uhlelo lokufeza izinhlobo zensimbi engagqwali oluphephile kakhulu kanye nokusebenza kahle kwezindleko.
I-S35656 (QN1804) ithembele ekumelaneni kwayo okuhle kakhulu nokugqwala, ukushibilika kanye nezakhiwo zayo zomshini ezisezingeni eliphansi lokushisa ezizofakwa ku-GB/T150.2-2024 “Izitsha Zokucindezela Ingxenye 2: Izinto” kanye ne-GB/T713.7-2023 “Ipuleti Lensimbi Nensimbi Yemishini Yokucindezela” Enengxenye 7: Insimbi Engagqwali Nensimbi Emelana Nokushisa” kanye nezinye izindinganiso ezimbili zikazwelonke ezihlobene nezitsha zokucindezela. Eminyakeni embalwa edlule, insimbi engagqwali yochungechunge lwe-QN yakhe uchungechunge lwezimboni oluzinzile futhi isetshenziswe ngamaqoqo emikhakheni eminingi yesakhiwo esithwala imithwalo efana nobunjiniyela besitimela esisheshayo, izakhiwo ezenziwe kusengaphambili, ubunjiniyela besitimela esingaphansi komhlaba, amandla, ubunjiniyela bolwandle kanye nezitsha zokucindezela.
Ukupholisha nge-electroinqubo yokuqedela nge-electrochemical esusa ungqimba oluncane lwezinto engxenyeni yensimbi, ngokuvamile insimbi engagqwali noma ama-alloy afanayo. Le nqubo ishiya ukuqeda kwendawo okukhazimulayo, okubushelelezi, nokuhlanzekile kakhulu.
Obeye aziwe njengoukupholisha nge-electrochemical, ukupholisha nge-anodicnomaukupholisha nge-electrolytic, ukupholisha ngogesi kuyasiza kakhulu ekupholiseni nasekususeni izingcezu ezibuthakathaka noma ezine-geometri eziyinkimbinkimbi. Ukupholisha ngogesi kuthuthukisa ukuqeda kobuso ngokunciphisa ukugoba kobuso ngamaphesenti afinyelela ku-50%.
Ukupholisha nge-electro kungacatshangwa ngokuthii-electroplating ebuyela emuvaEsikhundleni sokwengeza ungqimba oluncane lwama-ion ensimbi ashajwe kahle, i-electropolishing isebenzisa ugesi kagesi ukuncibilikisa ungqimba oluncane lwama-ion ensimbi esixazululweni se-electrolyte.
Ukupholisha nge-electro insimbi engagqwali kuyindlela evame kakhulu yokusebenzisa ukupholisha nge-electro. Insimbi engagqwali epholisha nge-electro inomphetho obushelelezi, ocwebezelayo, ohlanzekile kakhulu omelana nokugqwala. Nakuba cishe noma iyiphi insimbi izosebenza, izinsimbi ezipholisha nge-electro insimbi engagqwali engu-300 no-400.
Ukuqedwa kwe-electroplating kunezindinganiso ezahlukene zokusetshenziswa ezinhlotsheni ezahlukene. Lezi zinhlelo zokusebenza zidinga ububanzi obuphakathi bokuqeda. I-Electropolishing inqubo edlula lapho ipayipi lensimbi engagqwali elipholishiwe nge-Electropolished lincishisiwe. Lokhu kwenza amapayipi anembe kakhudlwana ngobukhulu futhi ipayipi le-EP lingafakwa ngokunemba ezinhlelweni ezibucayi njenge-izicelo zezimboni zemithi.
Sinemishini yethu yokupholisha futhi sikhiqiza amashubhu okupholisha e-electrolytic ahlangabezana nezidingo zemikhakha eyahlukene ngaphansi kokuqondiswa yithimba lobuchwepheshe laseKorea.
I-EP Tube yethu isesimweni segumbi elihlanzekile le-ISO14644-1 Class 5, ithubhu ngalinye lihlanzwa ngeubumsulwa obuphezulu kakhulu (UHP)i-nitrogen bese ivalwa bese ifakwa emasakeni amabili. Isitifiketi esifanela amazinga okukhiqiza epayipi, ukwakheka kwamakhemikhali, ukulandeleka kwezinto, kanye nokuba lukhuni okuphezulu kwendawo yonke sinikezwa kuzo zonke izinto.
