Yam khoom tiag tiag yog dab tsi
Aluminium composite phaj yog lub tiaj tiaj tiaj tiaj: ob daim tawv txhuas sib cais los ntawm cov thermoplastic los yog cov ntxhia pob zeb -cov tub ntxhais ua tiav, sib txuas los ntawm cov nplaum nplaum los yog los ntawm cov txheej txheem kub - yaj ntawm cov kab lamination txuas ntxiv. Lub vaj huam sib luag niaj hnub yog 4 hli tag nrho nrog 0.3 mus rau 0.5 hli tawv hla 3 hli core. Cov tawv nqaij feem ntau yog 1100, 3003 lossis 3105 daim ntawv nrog lub kauj - siv txheej, thiab cov tub ntxhais yog tsawg- ntom polyethylene los yog cov ntxhia pob zeb - cov nplaim hluav taws kub - retardant compound.
Cov tawv nqaij ua lub luag haujlwm ntawm cov qauv thiab huab cua. Cov tub ntxhais sib cais cov tawv nqaij kom lub vaj huam sib luag ua haujlwm raws li cov tawv tawv, tiaj tus phaj ntawm qhov hnyav, nrog qhov ntom ntom li ib feem peb ntawm cov khoom txhuas ntawm tib lub thickness. Tias yog vim li cas cov khoom siv yog siv rau loj facade teb, soffits, canopies, signage thiab tsheb cladding.
Hom Core thiab Kev Ua Haujlwm Hluav Taws Xob
Core chemistry yog ib qho tseem ceeb tshaj plaws kev xaiv sib txawv. Lub vaj huam sib luag polyethylene coj tus cwj pwm tsis zoo hauv qhov hluav taws kub vim tias cov khoom siv polymer ua rau roj, thaum lub pob zeb hauv av - puv core txwv cov cua sov. Cov tshuaj tiv thaiv hluav taws raug cais raws li EN 13501-1, thiab kev faib tawm yuav tsum tau muab los ntawm ib daim ntawv qhia txog kev tsim kho tshwj xeeb, vim tias daim tawv nqaij tuab, cov qauv tsim thiab txheej txheej tag nrho cuam tshuam rau qhov tshwm sim.

Cov Qauv thiab Cov Qauv Ntsuas
Cov qauv khoom thiab cov qauv kev sim rau cov vaj huam sib luag sib xyaw poob rau hauv peb pawg. Cov khoom lag luam thiab cov kev xav tau dav dav rau aluminium composite panels siv hauv cov ntaub thaiv phab ntsa yog them los ntawm GB / T 17748 hauv Suav cov txheej txheem thiab los ntawm kev sib npaug hauv lub teb chaws specifications lwm qhov. Bond integrity yog ntsuas los ntawm kev kuaj tev, tshwj xeeb tshaj yog ASTM D903 rau tev lub zog ntawm cov nplaum nplaum, los ntawm kev nce toj nruas tev txoj hauv ASTM D1781, thiab los ntawm cov kab xev adhesion hauv ASTM D3359 rau txheej adhesion. Hluav taws kub thiab cov qauv kev ua tau zoo raug soj ntsuam los ntawm ASTM E84 rau cov yam ntxwv ntawm qhov kub hnyiab thiab los ntawm ASTM E330 / E330M rau cov qauv kev ua tau zoo nyob rau hauv cov huab cua sib txawv zoo li qub.
Thaum muas, thov rau peb cov ntaub ntawv ua ke: daim ntawv pov thawj zeb rau cov tawv nqaij alloy thiab temper, daim ntawv qhia txog lub zog tev ntawm cov khoom ntau lawm, thiab daim ntawv qhia kev faib hluav taws xob npe rau kev tsim kho. Lub vaj huam sib luag tau lees paub ntawm qib 3 hli sab hauv tsis hloov daim ntawv pov thawj ntawd mus rau 4 hli sab nrauv specification.
Fabrication thiab Installation txwv
Composite phaj yog routed thiab folded, tsis welded. Tus txheej txheem fabrication txiav ib tug zawj los ntawm ib daim tawv nqaij thiab cov tub ntxhais, tawm hauv ib tug nyias pob khawm ntawm cov tawv nqaij rov qab uas yog ces folded, thiab lub resulting ces kaum yog kaw nrog ib tug structural los yog sealant nplaum. Lub zog ntawm daim ntawv cog lus ntawm txoj kab uas hla txoj kab yog qhov tsis muaj zog ntawm lub tshuab ua tiav, yog li qhov kev sib sib zog nqus thiab cov nplaum siv yuav tsum tau tswj kom ua tiav cov txheej txheem.
Kev kho yuav tsum tso cai rau thermal txav. Txhuas nthuav dav txog 23 x 10-6 ib℃degree, yog li lub vaj huam sib luag 2 m hloov ntev li ntawm 0.9 hli hla qhov kub ntawm 20℃viav vias. Cov vaj huam sib luag tau tuav ntawm ib qho kev sib txuas nrog cov ntsiab lus ruaj khov thiab zawv zawg, thiab lub cheeb tsam yuav tsum tau nruab rau qhov tsim sib koom ua ke dav dua li pob tw. Qhov twg lub vaj huam sib luag ntsib steel, cais gaskets tiv thaiv galvanic corrosion ntawm qhov kho.
Qhov twg Composite Phaj yog txoj kev xaiv
Peb lub luag haujlwm haum rau cov khoom siv: loj tiaj tiaj qhov chaw uas tsis muaj qhov hnyav thiab zoo meej flatness teeb meem ntau tshaj qhov cuam tshuam; re- cladding thiab renovation qhov twg cov qauv uas twb muaj lawm tsis tuaj yeem nqa cov khoom tuag ntxiv; thiab cov khoom tsim xws li lub cev tsheb, cov paib thiab cov khoom siv sab hauv uas cov qhaub cij tuaj yeem raug txiav thiab folded ntawm cov khoom txheem. Rau siab - cuam tshuam los yog siab - cov ntawv thov, cov ntawv txhuas khoom lossis cov hlau honeycomb vaj huam sib luag ua tau zoo dua, thiab cov vaj huam sib luag sib xyaw yuav tsum tsis txhob raug kho raws li qhov sib npaug.
Cov lus nug nquag
Q:Dab tsi yog qhov txawv ntawm aluminium composite vaj huam sib luag thiab khoom txhuas ntawv?
A: Cov khoom sib xyaw ua ke yog ib qho nyuaj ntawm ob daim tawv nqaij nyias hla lub polymer lossis pob zeb hauv av. Nws yog ntau sib dua thiab flatter ntawm tib lub thickness, tab sis nws tsis yog weldable thiab muaj kev cuam tshuam qis dua li cov ntawv.
Q:Hom tub ntxhais puas cuam tshuam rau kev ua haujlwm hluav taws?
A: Yog, txiav txim siab. Mineral-cov nplaim hluav taws puv-cov retardant cores tuaj yeem ua tiav cov nplaim hluav taws kub ntawm 0 txog 25 hauv qab ASTM E84; polyethylene cores tsis tuaj yeem. Kev faib tawm tsuas yog siv rau kev sim tsim.
Q:Qhov kev ntsuas twg ntsuas qhov kev sib raug zoo ntawm daim tawv nqaij thiab cov tub ntxhais?
A: Peel kuaj, feem ntau ASTM D903 rau tev lub zog thiab ASTM D1781 rau kev nce toj nruas tev txoj kev. Txheej adhesion raug kuaj cais los ntawm ASTM D3359.
Q:Yuav ua li cas yog ib tug composite vaj huam sib luag folded?
A: Los ntawm routing V-groove los ntawm ib daim tawv nqaij thiab cov tub ntxhais thiab folding cov tawv nqaij seem li pob khawm, ces kaw lub ces kaum nrog nplaum. Routing qhov tob yog qhov tseem ceeb rau lub zog tiav.
Q:Cov vaj huam sib luag puas tuaj yeem siv rau hauv siab -nce facades?
A: Tsuas yog thaum qhov kev tsim kho tshwj xeeb tuav cov tshuaj tiv thaiv uas yuav tsum tau ua - rau - kev faib hluav taws kub rau hom tsev ntawd, thiab daim ntawv qhia kev faib tawm rau lub vaj huam sib luag yog muaj rau kev pom zoo.
Q:Dab tsi txheej yuav tsum tau teev rau sab nrauv panels?
A: Ob -coat 70% PVDF system nrog qhov tsawg kawg nkaus 25 micrometer qhuav zaj duab xis thickness, validated rau AAMA 2605 rau xim thiab gloss tuav.
