Dab tsi yog qib ntawm tantalum?
Tantalum qib feem ntau yog teem raws li nws cov tshuaj muaj pes tsawg leeg thiab cov khoom. Cov hauv qab no yog qee qib ntawm cov ntshiab tantalum thiab tantalum alloys:
Ntshiab Tantalum:
R05200: Qhov no yog qib hluav taws xob ntshiab tantalum nrog ntau dua purity.
R05400: Qhov no yog ntshiab tantalum rau kev lag luam siv.
Tantalum alloy:
Ta-2.5W (R05252): Tantalum alloy muaj 2.5% tungsten, feem ntau siv rau hauv cov ntawv thov kub.
Ta-10W (R05255): Tantalum alloy muaj 10% tungsten, nrog rau qhov kub thiab txias zog thiab corrosion kuj.
Ta-40Nb (R05240): Tantalum alloy muaj 40% niobium, siv nyob rau hauv qhov kub thiab txias thiab corrosive ib puag ncig.
Cov qhabnias no feem ntau muaj npe raws li United States Unified Numbering System (UNS), lwm lub tebchaws lossis cheeb tsam yuav siv cov qauv sib txawv. Thaum xaiv cov khoom siv tantalum, nws yog qhov zoo tshaj rau xa mus rau cov qauv tsim nyog thiab cov lus qhia tshwj xeeb kom ntseeg tau tias nws ua tau raws li qhov xav tau ntawm koj daim ntawv thov tshwj xeeb.
Cov qauv rau tantalum khoom xws li tantalum hlau, tantalum rods, tantalum daim hlau, tantalum foils, thiab tantalum grounding rings feem ntau yog teem los ntawm txawv teb chaws, lub teb chaws, los yog cov koom haum kev lag luam. Cov hauv qab no yog qee cov qauv uas npog cov khoom tantalum:
1. ASTM tus qauv:
ASTM B365: Npog cov qauv tshwj xeeb rau tantalum thiab tantalum alloy hlau, pas nrig, thiab cov duab.
ASTM B708: suav nrog cov kev cai rau tantalum thiab tantalum alloy daim hlau, nplooj ntawv, thiab foils.
2. AMS specifications:
AMS 7849: Qhia meej tantalum ntshiab thiab tantalum alloys rau cov ntawv thov kub.
AMS 4902: Yuav tsum muaj rau Tantalum thiab Tantalum Alloy Sheets thiab Foils rau Kev Siv Khoom.
3. ISO cov qauv:
TS EN ISO 13782: Npog cov khoom siv hlau siv hauv kev kho mob cog, suav nrog tantalum.
4. MIL specifications:
MIL-T-81556: Qhia meej txog qhov yuav tsum tau muaj rau tantalum thiab tantalum alloys hauv kev siv dav hlau.
5. Lub teb chaws tus qauv:
Ntau lub teb chaws tuaj yeem muaj lawv cov qauv hauv tebchaws, xws li Suav Tebchaws Standards (GB) lossis European Standards (EN).
