Nrog txoj kev loj hlob ntawm aluminium profile tshuab, qhov ua tau zoo ntawm aluminium profile tau txais ntau dua thiab ntau dua. Lub tiaj tus ntawm cov dav hlau profile yog ib qho ntawm cov ntsuas yuav tsum tau ua zoo. Lub dav hlau xav tau ntawm aluminium profiles tau txhais nyob rau hauv tus qauv GB5237 ntawm aluminium alloy tsim profile. Lub dav hlau sib txawv hauv cov khoom loj tau ua txhaum yog qhov yuav tsum tau ua rau lub dav hlau.
Txoj kev dav dav yog hais txog: tus kav ntev ntev 25 hli yog leaned tawm tsam nrog concave nto ntawm qhov profile raws qhov dav, thiab qhov siab tshaj qhov kis tus nqi (F1) nruab nrab ntawm tus pas ntsuas thiab concave nto ntawm qhov profile yog ntsuas. Tus nqi no (F1) yog lub dav hlau ntawm qhov tsis txaus 25 hli dav ntawm qhov profile Gap: Qaij tus kav uas nws qhov ntev ntev tshaj li qhov dav ntawm qhov profile tiv thaiv qhov sib npaug ntawm qhov profile, thiab ntsuas qhov sib txawv ntau (F) ntawm tus pas ntsuas thiab concave nto ntawm qhov profile. Tus nqi no (F1) yog lub dav hlau kis ntawm qhov profile thoob plaws nws qhov dav.
Lub dav hlau kis kuj yog qhov uas peb feem ntau hais tias lub npoo yog tiaj thiab unyielding. Qhov me dua cov nqi sib txawv, hais lus kub nws yog. Qhov ntsuas ntawm lub dav hlau tshem yog qhov xav tau qhov loj me ntawm ntu, tsis yog hais txog qhov yuav tsum ua kom zoo li lub cev (lub cev thiab txoj haujlwm), yog li cas cov duab ntawm cov pab pawg tau txhais? Qhov ntsuas pom qhov txawv ntawm qhov nkhaus thiab qhov sib txawv ntawm qhov sib txawv, qhov sib txawv tus nqi h, T Qhov ntau me me zoo dua, yog tias nws yog 0, tsis muaj qhov tsis sib txawv hauv kev ua haujlwm. Txawm hais tias qhov no yog qhov kev xav theoretical, yuav tsum muaj kev sib pauv hauv kev muaj tiag. Yog li puas muaj ib lub sijhawm rau qhov dav thiab unyielding ntawm cov khoom ntawm topography pawg? Yog lawm, uas yog lub tiaj. Aluminium alloy profile.
Flatness hais txog qhov teeb meem ntawm macroscopic qhov siab ntawm cov substrate txheeb ze rau lub dav hlau zoo tagnrho. Cov cheeb tsam pabcuam yog thaj chaw nruab nrab ntawm ob lub dav hlau sib law liag sib cais los ntawm cov kev pabcuam tus nqi t. Lub dav hlau ntawm cov khoom lag luam yog inflexible, muab tso rau ntawm qhov chaw siv, qhov chaw qis tshaj yog nyob ntawm qhov chaw siv, thiab qhov kev ncua deb ntawm qhov chaw siab tshaj thiab cov ntsiab lus siv yog qhov tiaj. Piv nrog dav hlau tshem tawm, qhov ntsuas viav vias thiab twisting tau hais los saum toj no, feem ntau nkag siab tias flatness yog cov kev ua tau zoo ntawm dav hlau tshem, qib nkhaus thiab sib tw.
