Tsis ntev los no, lub teb chaws tus qauv GB / T20878-2024 "Stainless Steel Qib thiab Chemical Compositions", kho los ntawm Metallurgical Industry Information Standards Research Institute thiab koom nrog Fujian Qingtuo Special Steel Technology Research Co., Ltd. thiab lwm cov chav nyob, tau tso tawm thiab yuav yuav tsum tau ua thaum Lub Ob Hlis 1, 2025.. Tom qab ze li ntawm rau xyoo ntawm kev siv zog tsis tu ncua, Qingtuo Group nws tus kheej tsim cov nitrogen-muaj zog austenitic stainless hlau QN series, suav nrog S35250 (QN1701), S25230 (QN1801), S35657 (QN1803), S35656 (QN538), S35656 (QN1804), corrosion kuj qib xws li QF1804), S35706 (QN2008), S35886 (QN1906) thiab S35887 (QN2109) tau suav nrog hauv cov qauv no, ua kom cov hlau tsis muaj ntau yam qauv thiab muab lub zog siab, hnav, thiab siab corrosion kuj rau thaj tsam ntawm cov kabmob load-bearing. Txoj kev npaj ua tiav ntawm stainless hlau ntau yam nrog kev nyab xeeb thiab kev ua tau zoo.
S35656 (QN1804) tso siab rau nws qhov zoo tshaj plaws corrosion kuj, weldability thiab qis-kub txhua yam khoom kom muaj nyob rau hauv GB / T150.2-2024 "Pressure Vessels Part 2: Materials" thiab GB / T713.7-2023 "Steel Plate thiab Steel rau Cov Khoom Siv Siab "Nrog Tshooj 7: Stainless Hlau thiab Kub-Resistant Steel" thiab lwm yam ob lub teb chaws tus qauv muaj feem xyuam rau cov hlab ntsha siab. Ob peb xyoos dhau los, QN series stainless hlau tau tsim ib qho kev lag luam ruaj khov thiab tau siv rau hauv cov khoom siv hauv ntau cov qauv kev lag luam xws li high-speed rail tunnel engineering, prefabricated vaj tse, subway engineering, zog, dej hiav txwv engineering thiab cov hlab ntsha siab.
Electropolishingyog cov txheej txheem electrochemical tiav uas tshem tawm cov txheej nyias ntawm cov khoom siv hlau, feem ntau stainless hlau lossis cov hlau zoo sib xws. Cov txheej txheem tawm ntawm ci iab, du, ultra-ntshiab nto tiav.
Kuj hu uaelectrochemical polishing, anodic polishinglos yogelectrolytic polishing, electropolishing yog tshwj xeeb tshaj yog pab tau rau polishing thiab deburring qhov chaw uas tsis yooj yim los yog muaj complex geometry. Electropolishing txhim kho qhov chaw tiav los ntawm kev txo qhov roughness txog li 50%.
Electropolishing tuaj yeem xav taurov qab electroplating. Es tsis txhob ntxiv cov txheej nyias nyias ntawm cov hlau ions zoo, electropolishing siv hluav taws xob tam sim no los yaj txheej nyias ntawm cov hlau ions rau hauv cov tshuaj electrolyte.
Electropolishing ntawm stainless hlau yog feem ntau siv electropolishing. Electropolished stainless hlau muaj ib tug du, ci, ultra-ntxuav tag uas tiv thaiv corrosion. Txawm hais tias yuav luag txhua yam hlau yuav ua haujlwm, feem ntau cov hlau electropolished yog 300- thiab 400-series stainless hlau.
Kev ua tiav ntawm electroplating muaj cov qauv sib txawv rau kev siv sib txawv. Cov ntawv thov no xav tau qhov nruab nrab ntawm qhov kawg. Electropolishing yog ib txheej txheem los ntawm qhov tseeb roughness ntawm Electropolished Stainless hlau yeeb nkab yog txo. Qhov no ua rau cov kav dej muaj tseeb dua hauv qhov ntev thiab EP Yeeb Nkab tuaj yeem ntsia tau nrog qhov tseeb hauv cov tshuab rhiab zoo likev siv tshuaj siv tshuaj.
Peb muaj peb tus kheej polishing cov cuab yeej thiab tsim electrolytic polishing raj uas ua tau raws li qhov yuav tsum tau muaj ntawm ntau lub teb raws li kev taw qhia ntawm pab pawg neeg Kauslim.
Peb EP Tube hauv ISO14644-1 Chav Kawm 5 huv chav huv, txhua lub raj yog purged nrogUltra siab purity (UHP)nitrogen thiab tom qab ntawd capped thiab ob hnab ntim. Daim ntawv pov thawj tsim nyog rau tubing cov qauv tsim, tshuaj muaj pes tsawg leeg, cov khoom siv traceability, thiab qhov siab tshaj plaws ntawm qhov roughness yog muab rau txhua yam khoom siv.
