Lub rooj zaum fais fab, raws li cov cuab yeej tawm tshiab rau kev txav qeeb, tau maj mam lees paub los ntawm ntau tus neeg laus thiab cov neeg tsis taus. Yuav ua li cas peb yuav ibraug nqi hluav taws xob lub rooj zaum muaj log?

Raws li kev lag luam sab hauv rau ntau tshaj kaum xyoo, kuv xav luv luv pab koj daws qhov teeb meem no los ntawm ntau yam. Thawj qhov uas peb yuav tsum paub yog tias txhua pab pawg thiab cov neeg siv nws tus kheej qhov xwm txheej thiab kev siv ib puag ncig sib txawv, uas tseem ua rau muaj qhov sib txawv ntawm cov khoom yuav.

Cov khoom siv feem ntau yog muab faib ua carbon steel, aluminium alloy, aerospace titanium aluminium alloy thiab magnesium alloy, carbon fiber.

1. Cov khoom siv carbon steel.

Carbon steel thav duab feem ntau yog siv rau hauv cov rooj zaum hnyav hnyav thiab qee lub npe tsim los ntawm cov chaw tsim khoom me, cov rooj zaum hnyav hnyav siv steel ncej txhawm rau txhim kho lub cev tawv thiab kev ruaj ntseg, piv txwv li, ntau lub tsheb loj muaj steel ncej thiab cov tsheb me tuaj yeem siv txhuas yog tib yam vim li cas, cov chaw tsim khoom me tsim cov rooj zaum muaj log siv steel ncej vim qhov kev ua haujlwm thiab vuam txheej txheem yuav tsum muaj tsawg dua vim li cas cov khoom siv steel kuj yog vim li cas tus nqi qis. ua haujlwm thiab vuam thiab pheej yig dua.

2. Aluminium & titanium-aluminium alloy

Aluminium alloy thiab titanium aluminium alloy, ob cov ntaub ntawv no yog feem ntau ntawm kev ua lag luam rau lub rooj zaum fais fab, lawv yog 7001 thiab 7003 ob hom aluminium, uas yog, txhuas nrog lwm cov khoom sib xyaw ntxiv rau nws, lawv cov yam ntxwv tsis tshua muaj siab thiab siab zog, zoo plasticity kuj thiab corrosion kuj, muab tso rau nws intuitively yog lub teeb thiab muaj zog aluminium alloy txheej txheem. titanium-aluminium alloy vim nws lub zog thiab corrosion kuj. Raws li lub melting point ntawm titanium yog siab heev, ncav cuag 1942 degrees, uas yog ntau tshaj li 900 degrees siab tshaj kub, kev ua thiab vuam txheej txheem yog ib txwm nyuaj heev thiab tsis tuaj yeem tsim los ntawm ib tug me me kev cog qoob loo, yog li lub rooj zaum ua los ntawm titanium-aluminium alloy yog kim dua. Cov qub yog tsim rau kev siv tsis tu ncua thiab txoj kev zoo thiab kev tsav tsheb, thaum cov neeg siv uas siv nws ntau zaus, feem ntau yuav tsum tau nqa nws, thiab feem ntau tsav tsheb ntawm lub qhov dej thiab txoj kev tsis sib haum tuaj yeem xaiv lub rooj zaum ua los ntawm titanium-aluminium alloy.

3. Magnesium alloy

Magnesium alloy yog raws li magnesium los koom nrog lwm cov ntsiab lus ntawm cov hlau. Nws cov yam ntxwv yog: qhov ceev me me, lub zog siab, muaj peev xwm tiv thaiv zoo li txhuas alloy, qhov feem ntau dav siv yog magnesium-aluminium alloy. Magnesium yog lub teeb tshaj plaws ntawm cov khoom siv hlau, nrog rau lub ntiajteb txawj nqus ntawm kwv yees li ob feem peb ntawm txhuas thiab ib feem peb ntawm cov hlau, thiab siv magnesium rau lub rooj zaum logyog npaj kom ua tiav ntau "lightness" ntawm lub hauv paus ntawm aluminium.
