Corrosion -} tiv taus niobium xaub

Kev tsim cov tshuaj corrosion -} resist resistant niobium hlau pib nrog lub siab thiab huv- purity niobium hlau. Los ntawm kev siv electron nqaj melting (EBM) thiab nqus ARC melting (var) ntawm Niobium raw cov ntaub ntawv yog nce siab dua lossis sib npaug nrog cov ntsiab lus impurity xws li oxygen cov pa (O<100ppm) and nitrogen (N<50ppm) is strictly controlled. After the tube blank is preliminarily formed by hot extrusion, the wire diameter is gradually reduced to the target size through multiple cold drawing processes (with intermediate annealing), and the intermediate annealing is carried out in a vacuum environment of 800-1000 ° C to eliminate work hardening. The final wire diameter can be precisely controlled to be between 0.05-3.0mm with a tolerance of ± 0.005mm.
Txhawm rau txhim kho corrosion tsis kam, niobium xaim yuav tsum tau yauv mus rau kev kho kom ntev. Tau txais ib qho chaw du (RA tsawg dua lossis sib npaug rau 0.4 μ m) los ntawm electrolytic polishing los yog tshuaj electr electrium pentoxide (NB ₂) zaj duab xis passivation zaj duab xis. Nyob rau hauv cov kev cai tshwj xeeb, kev kho anodizing tuaj yeem siv los tsim cov tshuaj uas siv tau thickness oxide (feem ntau 1-5 μ m). Tsev Kawm Ntawv Kho Mob Niobium hlau kuj yuav tsum tau ntxuav thiab ua kom sov (xws li nitric acid passivation) kom ntseeg tau biocompatibility nyob rau hauv ISO 5832 tus qauv.

 

 

Cov yam ntxwv

Zoo heev corrosion

Nws muaj qhov ua tau zoo heev rau cov kua qaub muaj zog xws li nitric acid, hydrochloric acid, aquas regia, thiab cov kua roj ntsha (hauv 70% nitricia acid ib puag ncig). Cov Niobium pentoxide (NB ₂ ₂ o ₅) zaj duab xis passivation formed ntawm nws cov chaw tuaj yeem thaiv kev nkag mus ntawm corrosive media.


Biocompatibility thiab kev nyab xeeb

Ua raws li ISO 5832 thiab ASTM F2066 tus qauv khomob, tsis - kev ua kom lub cev nqaij daim ntaub, tiv taus lub cev kom haum rau cov khoom siv kho mob.

Cov Khoom Kub Kub Ruaj Ntseg Thiab Cov Khoom Siv Kho Mob

Lub suab tau yaj yog qhov siab li 2468℃c, thiab nws muaj lub zog zoo thiab ductility hauv qhov kub thiab nqus tsev, txhawb nqa cov txheej txheem kev ua haujlwm nyuaj.


Cov txheej txheem thiab kev yoog tau

Deventility zoo heev, haum rau precision ua kev puas ntsoog, xws li cov kab uas muaj hlua khi (xws li zoo li cov oxidation tsis kam)

Nws cov khoom tseem ceeb muaj xws li: tsis kam: ua kom muaj zog acid corrosion (txhua xyoo corrosion tus nqi<0.01mm in 70% nitric acid), biocompatibility (no cytotoxicity, no allergenicity), high melting point (2468 ° C), and good mechanical properties (tensile strength 400-1000 MPa, varying with wire diameter). Its density is 8.57 g/cm ³, with excellent ductility (elongation at break ≥ 15%), and supports precision machining such as weaving and bending.
Cov khoom lag luam Specifications npog hlau diamerers ntawm 0.05}} 3.0mm, tawv nqaij rau cov kev daws teeb meem sib txawv (muag muag) thiab cov kev kho mob sib txawv (polishing, passivation). Cov ntawv thov tshwj xeeb yuav xav kom cov kev kho mob ntxiv (xws li cov txheej txheem uas ua kom zoo nkauj los txhim kho oxidation tsis kam). Corrosion Resistant Niobium hlau undergoes kev ntsuas nruj ua kom zoo, ua kom muaj kev cia siab rau corrosion), kom muaj kev cuam tshuam rau kev kho mob corrosion, kom ntseeg tau tias muaj kev cuam tshuam nrog kev kho mob, kev kho mob, thiab cov chaw ua haujlwm.
Corrosion Resistant Niobium xaim xaim, nrog nws cov roj muaj zog zoo tshaj tiv thaiv (txhua xyoo Corrosion tus nqi<0.01mm) and high temperature stability, has become an ideal material for resisting harsh environments in chemical equipment. The dense niobium pentoxide (Nb ₂ O ₅) passivation film formed on its surface can effectively resist the corrosion of nitric acid, hydrochloric acid and other media. For example, a large nitric acid production plant uses niobium wire woven reactor lining mesh, which has been continuously used for 3 years in a 70% nitric acid environment and at a temperature of 80 ° C without corrosion failure, and its service life is more than 5 times longer than traditional stainless steel. In addition, niobium wire is also used as an electrode connecting wire for electrolytic cells to maintain long-term conductivity stability in acidic electrolytes.
Lub biocompatibilibility (ua raws li iso 5832 txuj ci) thiab corrosion tsis kam rau lub cev ntawm cov khoom no ua rau nws cov ntaub ntawv tseem ceeb rau cov khoom siv kho mob. Piv txwv li, cov lus qhia kev sib tham nrog hlau yog ua los ntawm 0.2mm niobium hlau, thiab muaj nag lossis nag lossis daus, kom muaj kev nyab xeeb ntawm kev phais mob. Kev ntseeg lub zog hluav taws xob electridod
Nyob rau hauv cov av marine ib puag ncig, nws txoj kev tiv thaiv mus rau chloride ion corrosion yog qhov zoo dua li cov khoom siv hlau. Ib qho chaw dej hiav txwv dej hiav txwv Wealination siv Niobium Hlau Woven Lim Cheebtsam Hauv daim teb ntawm lub zog tshiab, Niobium xaub ua haujlwm ua ib qho kev tiv thaiv kev ntsuas rau hauv molten ntsev corrosion thiab irradiation ib puag ncig; Ib qho teeb meem ntws tawm siv Niobium hlau tam sim no Collector kom tswj electrochemical ruaj khov hauv acidic electrolyte rau ntau tshaj 10 xyoo.
Lub siab purity (ntau dua los yog sib npaug ntawm 99.95%) thiab saum npoo huv ntawm corrosion ntawm corrosion {} {Resistant Niobium xaim hluav taws xob ua tau raws li cov txheej txheem semiconductor. Ib qho chaw nres tsheb siv hluav taws xob siv 0.1mm Niobium xaim raws li CVD cov txheej txheem hluav taws xob kom tswj tau cov roj fluorive hauv cov chaw wafer. Hauv thaj teb ntawm lub tshuab nqus tsev kom sov, cov cua sov txhawb nqa network woven nrog rau cov kuab paug lossis lub tshuab nqus dej ntawm 1800℃c, ua kom muaj kev ntseeg tau ntawm cov txheej txheem cua sov.
Corrosion Resistant Niobium xaim hlau tau pom tias muaj tus nqi xws li thiab kev kho mob, thiab sline corrosion tsis kam, biocompatibility, thiab siab} kub ruaj khov. Cov ntaub ntawv thov cov ntaub ntawv tau ua pov thawj tias nws cov kev pabcuam lub neej tuaj yeem ncav cuag 3-5 zaug ntawm cov khoom siv thiab txhim kho kev ntseeg tau. Nrog kev nce qib ntawm kev kho mob saum npoo xws li nano passings cov yeeb yaj kiab thiab cov khoom siv ntawm Niobium hlau yuav txuas ntxiv mus rau cov chaw xav tau ntau.
