2. Lub cev muaj zog

Niobium daim ntawv rau cov hniav nyiaj hniav kub muaj kev tiv thaiv corrosion zoo, tsis yooj yim rau hlawv, siab melting point, siab ceev, thiab kev ua haujlwm zoo. Tsis tas li ntawd, nws kuj muaj thermal conductivity thiab hluav taws xob conductivity thiab muaj superconducting zoo heev thiab cov khoom sib nqus.

Nyob rau hauv cov nqe lus ntawm nws muaj pes tsawg leeg, niobium yog ib qho kev hloov pauv hlau nrog lub cim atomic Nb thiab atomic tooj 41. Nws feem ntau pom muaj nyob hauv cov zaub mov xws li columbite, tantalite, thiab pyrochlore.

Thaum siv los ua cov hniav nyiaj hniav kub, niobium ntawv tuaj yeem ua anodized los tsim ntau yam xim zoo nkauj. Qhov no yog vim qhov saum npoo ntawm cov hlau tuaj yeem hloov kho los ua ib txheej nyias, pob tshab oxide uas qhia txog lub teeb nyob rau hauv ntau yam xim. Anodized niobium daim ntawv tuaj yeem siv los tsim cov qhwv ntsej, caj dab, bracelets, thiab lwm yam ntawm cov hniav nyiaj hniav kub uas yog ob qho tib si ruaj thiab zoo nkauj.

Niobium ntawv tuaj yeem siv los ua cov hniav nyiaj hniav kub. Vim tias nws yog ntshiab heev thiab tiv taus corrosion, nws khaws nws cov luster zoo heev. Tsis tas li ntawd, nws kuj yog ib qho khoom zoo rau ib puag ncig vim nws tsis muaj cov hlau xws li tooj liab, npib tsib xee, thiab chromium, yog li nws yuav tsis ua rau muaj kev tsis haum rau ntawm daim tawv nqaij. Hauv kev tsim cov hniav nyiaj hniav kub, daim ntawv niobium feem ntau siv los ua cov saw caj dab, qhwv ntsej, nplhaib thiab lwm yam khoom zoo nkauj ntawm cov duab sib txawv thiab ntau thiab tsawg.

4. Cov hauv qab no yog cov txheej txheem dav dav rau kev tsim cov ntawv niobium rau cov hniav nyiaj hniav kub

1) Kev npaj cov ntaub ntawv: Txhawm rau rho tawm Niobium los ntawm cov ntaub ntawv raw los ua niobium daim ntawv, koj yuav tsum npaj cov ntaub ntawv raw ntawm Niobium ua ntej. Niobium yog cov hlau tsis tshua muaj peev xwm muab rho tawm los ntawm niobium ore. Tom qab cov ore mus los ntawm cov txheej txheem xws li kev pab cuam, cov extracted ntshiab Niobium tuaj yeem ua tiav tom qab hloov dua siab tshiab rau hauv ingots.

2) Kev Ua Haujlwm: Lub ingot yog ua tiav rau hauv nws tus kheej qhov loj lossis cov duab uas xav tau los ntawm cov khoom ua haujlwm ntawm qhov kub thiab txias, thiab Niobium tuaj yeem ua rau hauv daim ntawv los ntawm kev ua haujlwm txias. Nws kuj tseem yuav tsum tau siv cov yeeb yaj kiab tiv thaiv thaum ua haujlwm kom tsis txhob muaj cov av hauv nws.

3) Polishing: Niobium ntawv yog micro-polished coj ib tug smoother thiab smoother nto. Qhov no kuj yog ib qho tseem ceeb heev rau kev tsim cov hniav nyiaj hniav kub, vim hais tias qhov saum npoo ntawm niobium phaj rau cov hniav nyiaj hniav kub yuav tsum yog tus qauv.

4) Kev txiav txim tiav: Tom qab ua tiav cov txheej txheem, niobium phaj tuaj yeem siv los ua ntau yam hniav nyiaj hniav kub, xws li necklaces, bracelets, rings, tsej thiab lwm yam.

Cov saum toj no yog cov txheej txheem ntau lawm ntawm niobium ntawv rau kev tsim cov hniav nyiaj hniav kub. Cov kauj ruam yuav txawv me ntsis ntawm tus neeg muag khoom rau tus neeg muag khoom, tab sis feem ntau cov kauj ruam no yog tsim nyog.
