Kutshanje, i-GB/T20878-2024 standard “Stainless Steel Grades and Chemical Compositions”, ehlelwe yiMetallurgical Industry Information Standards Research Institute kwaye ithathe inxaxheba yiFujian Qingtuo Special Steel Technology Research Co., Ltd. kunye nezinye iiyunithi, ikhutshwe kwaye iza kusetyenziswa nge-1 kaFebruwari 2025. Emva kweminyaka ephantse ibe mithandathu yemizamo engapheliyo, iQingtuo Group yaziphuhlisa ngokuzimeleyo uthotho lwe-QN yentsimbi engagqwaliyo equlethe initrogen enamandla kakhulu, kuquka i-S35250 (QN1701), i-S25230 (QN1801), i-S35657 (QN1803), i-S35656 (QN1804), i-S35388 (Iimveliso ezinamazinga ahlukeneyo okumelana nokugqwala afana ne-QF1804), i-S35706 (QN2008), i-S35886 (QN1906) kunye ne-S35887 (QN2109) zifakiwe kulo mgangatho, ziphucula isakhiwo seentlobo zentsimbi engagqwali kwaye zibonelela ngamandla aphezulu, alula, kunye nokumelana nokugqwala okuphezulu kwicandelo lezakhiwo ezithwala imithwalo. Isicwangciso sokufezekisa iintlobo zentsimbi engagqwali ezinokhuseleko oluphezulu kunye nokusebenza kakuhle kweendleko.
I-S35656 (QN1804) ixhomekeke kukumelana kwayo okuhle nokugqwala, ukuwelda kunye neempawu zayo zoomatshini eziphantsi kobushushu eziza kubandakanywa kwi-GB/T150.2-2024 “Iinqanawa zoXinzelelo Icandelo lesi-2: Izinto” kunye ne-GB/T713.7-2023 “Ipleyiti yentsimbi kunye nentsimbi yezixhobo zoXinzelelo” kunye neCandelo lesi-7: Intsimbi engagqwaliyo kunye nentsimbi engamelani nobushushu” kunye neminye imigangatho emibini yesizwe enxulumene neenqanawa zoxinzelelo. Kwiminyaka embalwa edlulileyo, intsimbi engagqwaliyo yochungechunge lwe-QN yenze uthotho lwemizi-mveliso oluzinzileyo kwaye isetyenzisiwe kwiibhetshi kwiindawo ezininzi zemarike ezithwala umthwalo ezifana nobunjineli beendlela zikaloliwe ezikhawulezayo, izakhiwo ezenziwe kwangaphambili, ubunjineli bendlela ephantsi komhlaba, amandla, ubunjineli bolwandle kunye neenqanawa zoxinzelelo.
Ukucoca nge-electropolishingyinkqubo yokugqiba nge-electrochemical esusa umaleko omncinci wezinto kwinxalenye yesinyithi, ngesiqhelo intsimbi engatyiwayo okanye ii-alloys ezifanayo. Le nkqubo ishiya umphezulu okhazimlayo, ogudileyo, nococekileyo kakhulu.
Kwaziwa njengeukupolishwa nge-electrochemical, ukupolishwa nge-anodicokanyeukupolisha nge-electrolytic, ukupholisha ngombane kuluncedo kakhulu ekupholiseni nasekususeni iinxalenye ezibuthathaka okanye ezineejiyometri ezintsonkothileyo. Ukupholisha ngombane kuphucula ukugqitywa komphezulu ngokunciphisa uburhabaxa bomphezulu ukuya kuthi ga kwi-50%.
Ukupholisha nge-electropolishing kunokucingwa njengoukuphinda umbaneEndaweni yokongeza uqweqwe oluncinci lwee-ion zesinyithi ezitshajwe kakuhle, i-electropolishing isebenzisa umbane wamandla ukunyibilikisa umaleko oncinci wee-ion zesinyithi kwisisombululo se-electrolyte.
Ukupholisha nge-electropolishing yentsimbi engagqwaliyo yeyona ndlela ixhaphakileyo yokusebenzisa ukupholisha nge-electropolishing. Intsimbi engagqwaliyo epholisha nge-electropolishing inomphetho ogudileyo, okhazimlayo, ococekileyo kakhulu omelana nokugqwala. Nangona phantse nayiphi na intsimbi ingasebenza, iintsimbi ezipholisha nge-electropolishing ezixhaphakileyo ziyintsimbi engagqwaliyo engama-300 kunye nama-400.
Ukugqitywa kwe-electroplating kunemigangatho eyahlukeneyo yokusetyenziswa kwiinkqubo ezahlukeneyo. Ezi zicelo zifuna ukugqitywa okuphakathi. Ukucoca nge-electro yinkqubo edlula apho i-Electropolishing Stainless Pipe incitshiswa khona. Oku kwenza iipayipi zibe ngokuchanekileyo ngakumbi ngobukhulu kwaye i-EP Pipe ingafakwa ngokuchanekileyo kwiinkqubo ezinobuthathaka ezifanaizicelo zoshishino lweyeza.
Sinezixhobo zethu zokupolisha kwaye senza iityhubhu zokupolisha ze-electrolytic ezihlangabezana neemfuno zamacandelo ahlukeneyo phantsi kolwalathiso lweqela lobuchwephesha laseKorea.
Ityhubhu yethu ye-EP ikwimeko yegumbi elicocekileyo le-ISO14644-1 Class 5, ityhubhu nganye ihlanjululwe ngeubumsulwa obuphezulu kakhulu (UHP)i-nitrogen ize igqunywe ngesiciko ize ibekwe kabini. Isiqinisekiso esiqinisekisa imigangatho yemveliso yetyhubhu, ukwakheka kweekhemikhali, ukulandeleka kwezinto, kunye noburhabaxa bomphezulu ophezulu siyabonelelwa kuzo zonke izinto.
