Kub txoj kev Aluminium
Yog tias koj tsis ua, nyuaj heev txhuas yuav tawg thiab so thaum tsim. Aluminium melts ntawm 865 thiab 1, 240 degrees F, yog li koj pom tseeb tau ' tsis kub nws ntau npaum li hlau. Hauv qee txoj kev txhuas heats, khoov, thiab recrystallizes txoj kev hlau ua , thiab nyob rau hauv lwm txoj kev nws teb txawv heev.
Ntawm no, puas aluminium puas yooj yim?
Aluminium khoov, thiab nyob ntawm seb nws tau kho cua sov li cas yuav ntxiv dag zog rau nws. Rau feem ntau, txhuas yog kev zam txim ntau dua li carbon lossis graphite, raws li ob qho tib si tom kawg so los yog tawg. Yam tsawg kawg nrog cov txhuas koj muaj txoj hauv kev ncaj ncees ntawm kev khoov ib feem rov qab rau hauv cov duab rau siv ib ntus kom txog thaum hloov.
Tsis tas li, koj tuaj yeem khoov 6061 txhuas? 6061 . Qhov no yog ib qho ntawm ntau yam ntawm cov cua sov kho tsev neeg ntawm alloys. Nyob rau hauv lub annealed mob, nws tau siv rau khoov txij li qhov sib txawv ntawm qhov tawm los thiab tensile lub zog yog 10 Ksi thiab elongation yog mus txog 18%. Thaum nce mus txog T4 thiab T6 tempers, txawm li cas los xij, khoov peev xwm yuav txo tau.
Kuj Paub, cov hlau twg tuaj yeem khoov yam tsis muaj kev tawg?
Cov cuab yeej feem ntau siv rau tsev neeg pawg 1 txog 12 ntawm lub rooj zaum niaj hnub ntawm cov ntsiab lus. Nws yog lub peev xwm ntawm ib tug ruaj khov khoov los yog muab hammered rau hauv lwm yam duab tsis tawg . Piv txwv ntawm malleable hlau yog kub, hlau, txhuas, tooj liab, nyiaj, thiab txhuas.
Dab tsi yog qhov tsis muaj zog ntawm aluminium?
Aluminium alloys yuav warp ntawm qhov kub thiab txias thiab tsis zoo li hlau, tsis txhob ci liab ua ntej melting. Aluminium alloys kuj muaj qhov txo qis qis dua li cov hlau thiab yuav tsis muaj zog ntxiv nrog kev ntxhov siab ntxiv. Lawv tsis tshua muaj siv nyob rau hauv fabrication daim ntaub ntawv uas yuav tsum tau siab qaug zog tus nqi.

Nws puas yooj yim rau khoov aluminium?
Aluminium series 'muaj peev xwm khoov yuav txo qis thaum koj txav mus rau hauv cov npe ntawm tempers, los ntawm annealed mus rau T4 thiab T6. Khoov cov tempered alloys no tsis yooj yim sua, tab sis nws yog ib qho nyuaj heev thiab feem ntau yuav xav tau loj khoov radii kom tsis txhob tawg ntawm sab nraud ntawm khoov
Puas yog qhov kev thov rau iPhones nqi inelastic lossis elastic Vim li cas cov nyiaj tau los elasticity siab lossis qis?
Li no, nws tuaj yeem hais tias Iphone yog cov nyiaj tau los elastic, vim tias muaj tus nqi ntau dua 1. Nws yog ib qho zoo vim tias qhov feem pua nce ntawm qhov xav tau ntau dua qhov feem pua nce hauv cov nyiaj tau los. Kev nce hauv cov nyiaj tau los yuav ua rau muaj kev xav tau zoo li no
Dab tsi yog qhov phem tshaj ntsug lossis kab rov tav tawg?
Cov lus teb yooj yim yog yog. Cov kab nrib pleb feem ntau yog qhov tshwm sim ncaj qha ntawm lub hauv paus daws teeb meem, thiab cov no yog cov teeb meem ntau dua ntawm lub hauv paus. Kab rov tav kab nrib pleb feem ntau tshwm sim los ntawm cov av siab thiab feem ntau yog phem dua li cov kab nrib pleb
Puas yog Aluminium ntawv ci tawg?
Cov ntawv ci txhuas siv sijhawm txog 400 xyoo los rhuav tshem thiab txawm tias rov ua dua tshiab, feem ntau nws xaus rau hauv cov dej hiav txwv dej
Qhov twg zoo dua aluminium lossis cam khwb cia aluminium patio rooj tog?
Hnyav dua li extruded aluminium thiab ob qho tib si sib zog thiab ruaj khov dua li cov hlau wrought, cam khwb cia aluminium patio rooj tog yog thawj qhov kev xaiv rau feem ntau. Muab khoom nrog cov khoom zoo, ntev-ntev zoo hmoov coated tiav, cam khwb cia aluminium rooj tog paub tias yuav kav ntev li ntawm peb caug xyoo nrog kev saib xyuas me ntsis
