I kēia manawa koke nei, ua hoʻokuʻu ʻia ke kūlana aupuni GB/T20878-2024 "Stainless Steel Grades and Chemical Compositions", i hoʻoponopono ʻia e ka Metallurgical Industry Information Standards Research Institute a i komo pū ʻia e Fujian Qingtuo Special Steel Technology Research Co., Ltd. a me nā ʻāpana ʻē aʻe, a e hoʻokō ʻia ma Pepeluali 1, 2025. Ma hope o kahi kokoke i ʻeono mau makahiki o ka hoʻoikaika mau ʻana, ua hoʻomohala kūʻokoʻa ʻo Qingtuo Group i ka moʻo QN kila kila austenitic i hoʻoikaika nui ʻia me ka naikokene, me S35250 (QN1701), S25230 (QN1801), S35657 (QN1803), S35656 (QN1804), S35388 (Ua hoʻokomo ʻia nā huahana me nā pae pale ʻino like ʻole e like me QF1804), S35706 (QN2008), S35886 (QN1906) a me S35887 (QN2109) i loko o kēia kūlana, e hoʻonui ana i ke ʻano o ke kila kila a hāʻawi i ka ikaika kiʻekiʻe, ka māmā, a me ke kūpaʻa kiʻekiʻe i ka pala no ke kahua o nā hale e hāpai ana i ka ukana. ʻO ka hoʻolālā hoʻokō o nā ʻano kila kila me ka palekana kiʻekiʻe a me ke kumukūʻai kūpono.
Hilinaʻi ʻo S35656 (QN1804) i kona kūpaʻa maikaʻi loa i ka pala, ka hiki ke hoʻopili ʻia a me nā waiwai mechanical haʻahaʻa haʻahaʻa e hoʻokomo ʻia i loko o GB/T150.2-2024 "Nā Ipu Paʻa Māhele 2: Nā Mea Hana" a me GB/T713.7-2023 "Papa Kila a me ke Kila no nā Lako Paʻa" Me ka Māhele 7: Kila Kila a me ke Kila Pale Wela" a me nā kūlana aupuni ʻelua e pili ana i nā ipu paʻa. I nā makahiki i hala iho nei, ua hoʻokumu ke kila kila QN series i kahi kaulahao ʻoihana paʻa a ua hoʻohana ʻia ma nā ʻāpana ma nā kahua mākeke hoʻonohonoho ukana he nui e like me ka ʻenekinia tunnel kaʻaahi wikiwiki, nā hale i hana mua ʻia, ka ʻenekinia subway, ka ikehu, ka ʻenekinia moana a me nā ipu paʻa.
Hoʻopili uilahe hana hoʻopau electrochemical ia e wehe ana i kahi papa lahilahi o ka mea mai kahi ʻāpana metala, ʻo ke kila kila a i ʻole nā mea like. Waiho ke kaʻina hana i kahi ʻili ʻālohilohi, laumania, a maʻemaʻe loa.
Ua ʻike ʻia hoʻi ʻoka wili ʻana i ka electrochemical, ka wili ʻana i ka anodica i ʻoleka wili ʻana i ka electrolytic, he mea pono loa ka electropolishing no ka polishing a me ka deburring i nā ʻāpana palupalu a i ʻole he geometries paʻakikī. Hoʻomaikaʻi ka electropolishing i ka hoʻopau ʻana o ka ʻili ma ka hōʻemi ʻana i ka ʻoʻoleʻa o ka ʻili a hiki i ka 50%.
Hiki ke noʻonoʻo ʻia ka electropolishing e like meka hoʻopili uila hoʻohuliMa kahi o ka hoʻohui ʻana i kahi uhi lahilahi o nā ion metala i hoʻopiʻi maikaʻi ʻia, hoʻohana ka electropolishing i ke au uila e hoʻoheheʻe i kahi papa lahilahi o nā ion metala i loko o kahi hopena electrolyte.
ʻO ka electropolishing o ke kila kila ka hoʻohana maʻamau o ka electropolishing. He ʻano laumania, ʻālohilohi, a maʻemaʻe loa ke kila kila kila i electropolish ʻia e kūʻē ana i ka pala. ʻOiai e hana ana ka hapa nui o nā metala, ʻo nā metala i electropolish pinepine ʻia he 300- a me 400-series stainless steel.
He ʻokoʻa nā kūlana o ka hoʻopau ʻana o ka electroplating no ka hoʻohana ʻana i nā noi like ʻole. Pono kēia mau noi i ka laulā waena o ka hoʻopau ʻana. ʻO ka Electropolishing kahi hana ma o ka hoʻemi ʻana i ka ʻoʻoleʻa loa o ka Electropolish Stainless Steel Pipe. ʻOi aku ka pololei o nā paipu i nā ana a hiki ke hoʻokomo ʻia ka EP Pipe me ka pololei i nā ʻōnaehana koʻikoʻi e like me kanā noi ʻoihana lāʻau lapaʻau.
Loaʻa iā mākou kā mākou pono hana wili a hana i nā ʻōmole wili electrolytic e hoʻokō i nā koi o nā ʻano like ʻole ma lalo o ke alakaʻi ʻana a ka hui loea Korea.
ʻO kā mākou EP Tube ma nā kūlana lumi maʻemaʻe ISO14644-1 Class 5, ua hoʻomaʻemaʻe ʻia kēlā me kēia paipu memaʻemaʻe kiʻekiʻe loa (UHP)naikokene a laila uhi ʻia a hoʻopaʻa ʻia i ʻeke pālua. Hāʻawi ʻia ka palapala hōʻoia e hōʻoia ana i nā kūlana hana o ka paipu, ka haku mele kemika, ka hiki ke hahai ʻia nā mea, a me ka ʻoʻoleʻa o ka ʻili no nā mea āpau.
