Nyob rau hauv lub neej tam sim no,hluav taws xob lub rooj zaum, raws li txoj kev thauj mus los qeeb qeeb, tau maj mam lees paub los ntawm ntau tus neeg laus thiab cov neeg xiam oob qhab. Nrog rau kev vam meej ntawm tib neeg thiab kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, hom thiab kev teeb tsa ntawm lub rooj zaum hluav taws xob tau dhau los ua ntau thiab ntau dua, ntawm cov khoom siv ib leeg, muaj ntau hom, xws li carbon steel, aluminium alloy, magnesium alloy, thiab siab dua. -qib carbon fiber, aerospace titanium aluminium alloy, thiab lwm yam. Yog li thaum ntsib nrog ntau cov ntaub ntawv sib txawv, peb Yuav ua li cas xaiv lub rooj zaum fais fab uas raug nqi? Cov khoom siv twg zoo dua rau lub rooj zaum muaj zog hluav taws xob?
Ua ntej tshaj plaws, qhov 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 kev sib txawv ntawm cov khoom yuav khoom. Hauv qhov kev thov sib txawv no, peb yuav muab rau koj los ntawm cov hauv qab no Qee cov lus qhia thiab kev qhia meej.
Cov khoom siv feem ntau yog muab faib ua carbon steel, aluminium alloy, aerospace titanium aluminium alloy thiab magnesium alloy. Peb yuav tsis tham txog carbon fiber tam sim no (tus nqi siab thiab ob peb daim ntawv thov);
1. Cov khoom siv carbon steel:
Cov pa roj 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 cov ncej steel los txhim kho lub zog ntawm lub cev thiab kev tsav tsheb ruaj khov. Piv txwv li, cov thav duab ntawm ntau lub tsheb loj yog cov ncej steel. Rau tib lub laj thawj, tsheb tuaj yeem siv txhuas. Lub rooj zaum muaj log uas tsim nyob rau hauv cov chaw me me siv cov thav duab steel vim qhov no yuav tsum tau ua qis dua thiab cov txheej txheem vuam thiab pheej yig dua los tsim.
2. Aluminium alloy & titanium aluminium alloy
Aluminium alloy thiab titanium-aluminium alloy, cov khoom siv ob lub thav duab no nyob rau feem coob ntawm kev ua lag luam rau lub rooj zaum fais fab. Lawv yog ob hom khoom siv txhuas sib txawv, 7001 thiab 7003, uas txhais tau hais tias lwm cov khoom sib xyaw sib txawv yog ntxiv rau cov ntaub ntawv txhuas. Ua los ntawm cov hlau tsis muaj hlau, lawv cov cwj pwm tsis sib xws yog qhov muaj zog tsawg thiab lub zog siab, zoo yas tiv taus thiab corrosion tsis kam. Muab tso rau nws ntau intuitively, lawv yog lub teeb, muaj zog thiab yooj yim rau txheej txheem, thaum titanium-aluminium alloy muaj zog dua thiab corrosion kuj. Nws yog dav siv hauv aerospace teb, yog li nws tseem hu ua aerospace titanium aluminium alloy. Vim tias titanium muaj qhov melting siab heev, uas tuaj yeem ncav cuag 1942 degrees, uas yog ntau tshaj 900 degrees siab dua kub, nws cov txheej txheem thiab vuam yog ib txwm nyuaj heev. Nws tsis tuaj yeem tsim los ntawm cov nroj tsuag ua haujlwm me me, yog li aviation titanium aluminium Wheelchairs ua los ntawm alloy yog kim dua. Thaum xaiv ib qho kev yuav khoom, tus qub yog tsim rau cov neeg siv uas tsis tshua muaj kev siv, txoj kev zoo thiab ib puag ncig ntawm kev tsav tsheb, thaum cov neeg siv khoom siv ntau zaus, kev thauj mus los tsis tu ncua, thiab nquag tsav tsheb ntawm cov pas dej thiab cov tsheb sib tsoo tuaj yeem xaiv titanium-aluminium alloy wheelchairs. . .
3. Magnesium alloy
Magnesium alloy yog ib qho alloy raws li magnesium thiab ntxiv nrog rau lwm yam. Nws cov yam ntxwv yog: tsawg ntom, siab zog, loj elastic modulus, zoo cua sov dissipation, zoo poob siab absorbing, thiab muaj peev xwm tiv taus tej yam loads ntau dua aluminium alloys. Tam sim no, magnesium-aluminium alloys tau siv dav. Nws yog ib tug kuj lub teeb hlau ntawm cov tswv yim hlau. Qhov tshwj xeeb lub ntiajteb txawj nqus ntawm magnesium yog hais txog 2/3 ntawm txhuas thiab 1/4 ntawm hlau. Lub hom phiaj ntawm kev siv magnesium alloy rau lub rooj zaum lub rooj zaum yog kom ua tiav qhov hnyav dua raws li aluminium alloy. quantification” lub hom phiaj.
Cov saum toj no yog ob peb yam khoom siv lub rooj zaum log. Koj tuaj yeem xaiv raws li koj tus kheej siv ib puag ncig thiab koj tus kheej qhov xwm txheej.
