Aluminium Alloy Qhov rai Khoom Taw Qhia

Basic txhais
Lub npe lus Askiv: Aluminium qhov rais
Keeb kwm kev loj hlob
Thaum xyoo 1980s, aluminium alloy qhov rais- ua los ntawm txhuas alloy profiles- tshwm sim. Thaum lawv tau hais txog qee qhov kev tsis txaus ntawm cov qhov rais steel, cov profiles lawv tus kheej yog cov hlau thiab ua rau kub thiab txias. Yog li ntawd, tag nrho K- tus nqi (kub xa hluav taws xob) rau ob qho tib si steel thiab aluminium alloy qhov rais tshaj 6.0 W / (m²·K), ua tsis tiav hauv paus daws teeb meem txog kev sib khi thiab thermal rwb thaiv tsev; Txawm hais tias haum nrog cov iav insulating (ob chav glazing), tag nrho K- tus nqi tsuas yog ncav cuag li 4.5 W / (m²·K).
Los ntawm nruab nrab - mus rau - lig 1990s, "thermal so" (lossis "bridge-txiav") aluminium alloy qhov rais tau tshwm sim hauv khw, sawv cev rau cov khoom lag luam hwm zoo thaum lub sijhawm. Cov ntaub ntawv no muaj lub zog siab - lub zog, insulating cov khoom siv hluavtaws ntawm lawv cov tub ntxhais thiab siv cov thev naus laus zis kho mob xws li hmoov txheej, fluorocarbon txheej, thiab resin thermal luam ntawv, tso cai rau ntau qhov sib xyaw xim.
Qhov zoo ntawm thermal so aluminium alloy qhov rais suav nrog lub teeb yuag, lub zog siab, dej zoo heev thiab huab cua nruj, kev tiv thaiv hluav taws zoo dua, thaj chaw loj glazing, tiv thaiv atmospheric corrosion, lub neej ua haujlwm ntev, kev zoo nkauj zoo nkauj, thiab kev ua haujlwm zoo ib puag ncig.
Txawm li cas los xij, raws li cov qauv kev noj qab haus huv tau nce siab, muaj kev tsom mus rau kev noj qab haus huv, kev tiv thaiv ib puag ncig, thiab kev txuag hluav taws xob. Thermal break aluminium alloy qhov rais thiab PVC-U (yas{2}}steel) qhov rais feem ntau tsis sib haum xeeb nrog cov décor sab hauv los yog txaus siab rau niaj hnub zoo nkauj saj, thiab lawv tsis ua raws li lub teb chaws sib tw rau lub zog efficiency.
