Ntau yam hlau, yas, raw khoom thiab tshuaj siv los ntawm kev lag luam hluav taws xob. Qee yam ntawm cov hlau ntau dua muaj xws li tooj liab, lithium, tin, nyiaj , kub, npib tsib xee thiab txhuas.
Ib yam li ntawd, nws yog nug, dab tsi yog cov khoom siv uas muaj nqi tshaj plaws?
Cov "Precious" Precious Hlau nyob rau hauv lub ntiaj teb no
- Kub. Kub tau tseem yog ib qho ntawm cov khoom siv dav dav tshaj plaws rau kev nqis peev.
- Platinum. Platinum yog ib qho ntawm cov khoom muaj nqis tshaj plaws tom qab kub thiab nyiaj.
- Nyiaj.
- Rhodium.
- Ruthenium.
- Iridium.
- Qhov no greyish-dawb cov hlau muaj nuj nqis muaj nuj nqis rau nws qhov tsis tshua muaj, malleability, thiab ruaj khov.
- Osmium.
Tsis tas li ntawd, cov hlau dab tsi yog siv hauv Circuit Board? Feem ntau siv hlau Cheebtsam ntawm circuit boards yog tin lead alloys, siv nyob rau hauv tooj liab thiab solder muab conductivity [144]. Hais txog muaj nuj nqis hlau , circuit boards muaj kub, nyiaj, thiab platinum, nrog rau kev siv dav dav hlau , xws li tooj liab, txhuas, thiab hlau [142].
Ib yam li ib tug yuav nug, dab tsi yog cov khoom siv hluav taws xob feem ntau ua los ntawm?
Feem ntau niaj hnub no hluav taws xob tam sim no siv cov ntawv luam tawm Circuit Board ua los ntawm Cov ntaub ntawv xws li FR4, los yog pheej yig dua (thiab tsis tshua muaj hnav) Synthetic Resin Bonded Paper (SRBP, tseem hu ua Paxoline / Paxolin (cov cim kev lag luam) thiab FR2) - tus cwj pwm los ntawm nws cov xim xim av.
Cov ntaub ntawv dab tsi yog siv hauv cov khoom siv hluav taws xob?
Hlau. tooj liab feem ntau yog siv rau nws zoo heev conductivity thiab malleability (lub peev xwm los ua zoo li tus thiab mashed). Nckel, chromium , aluminium, txhuas, nyiaj thiab tin kuj siv. Cov hlau no nkag mus rau hauv cov khoom xws li resistors, capacitors thiab transducers.

Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog cov khoom siv hluav taws xob ntau tshaj plaws ntawm lub rooj zaum?
