Kev mob loj heev thiab kev qaug zog: lub caij nplooj ntoos hlav ua haujlwm thaum lub hauv siab kom muaj kev ntxhov siab tshaj plaws, thiab qaug zog ploj yog feem ntau los ntawm xaim npoo, rau kev siv lub sijhawm tseem ceeb thaum caij nplooj ntoos hlav, xws li tsheb cav valve feem ntau yuav tsum tau qaug zog lub neej 2.3 × 107 xuabmoos ~ 3.0 × 107 lub sij hawm, nyob rau hauv lub hnub poob siab lub caij nplooj ntoos hlav feem ntau yuav tsum tau 2.0 × 106 zaug ~ 5.0 × 106 zaug los yog lub neej qaug zog dua, uas nyob rau ntawm cov khoom qaug zog ntawm cov khoom ua ib qho kev thov siab heev.
Muaj ntau ntau yam uas cuam tshuam rau cov khoom qaug zog ntawm cov khoom siv, xws li tshuaj lom neeg muaj pes tsawg leeg ntawm cov khoom, qhov nyuaj, qhov purity ntawm cov hlau, qhov zoo thiab qhov microstructure, thiab lwm yam, tshwj xeeb tshaj yog qhov zoo ntawm cov khoom. Cov khoom tsis zoo, xws li kab nrawm, folding, nplai, xeb, khaus, khawb thiab qhov muag, yog ib qho yooj yim kom lub caij nplooj ntoos hlav ua hauj lwm los ntawm kev nyuab siab. Qhov kev nyuab siab ntawm qhov chaw feem ntau yog los ntawm qhov kev puas tsuaj rau qhov chaw qaug zog. Qaug zog qhov chaw kuj yog ib qho yooj yim nyob rau hauv qhov chaw dauv ntawm thawj qhov chaw, yog li nruj me ntsis tswj lub qhov tob tob qhov tseem ceeb kuj yog ib qho tseem ceeb heev kev ntsuas.
Yuav kom txhim kho tau cov khoom zoo nkauj ntawm lub caij nplooj ntoos hlav, cov nplais ntawm cov khoom yuav tsum tau polished los yog polished, ua ntej stripping cov hlau wire stripping txheej txheem stripping txheej txheej ntawm daim tawv nqaij, ces feem ntau ntawm cov teeb meem tsis zoo yuav raug tshem tawm. Caij nplooj ntoos hlav thaum tshav kub kub yuav siv tau los tswj cov cua los yog kev nqus tsev vacuum kom tiv thaiv kom tsis txhob ntab thiab oxidation.
