Hauv lub ntiaj teb uas cov ntaub ntawv siv hauv tsev thiab cov khoom siv sib xyaw ua ke hauv kev lag luam hloov zuj zus, qhov kev xav tau rau cov vaj huam sib luag uas sib dua, muaj zog heev, thiab ruaj khov yog qhov siab tshaj plaws. Thaum cov tawv nqaij txhuas ntawm Aluminium Composite Panels (ACPs) muab qhov zoo nkauj thiab tiv taus huab cua, nws yog lub hauv paus - thiab qhov tshwj xeeb tshaj yog, qhov kev txhawb nqa hauv lub hauv paus ntawd - uas ua haujlwm ua tus phab ej tsis tau paub, tswj hwm kev ua haujlwm ntawm lub vaj huam sib luag. Ntawm cov kev nce qib tshiab,triaxial scrim txhawb nqatab tom tshwm sim los ua ib qho thev naus laus zis hloov pauv kev ua si, muab kev sib npaug zoo dua ntawm cov khoom uas unidirectional lossis biaxial reinforcements tsis tuaj yeem sib piv.
Cov scrims ib txwm muaj, nrog lawv cov bidirectional (0 ° thiab 90 °) orientation, muab lub zog zoo. Txawm li cas los xij, lawv tuaj yeem raug rau shear rog thiab diagonal kev ntxhov siab, uas ua rau deformation lossis delamination. Triaxial scrim, tus yam ntxwv los ntawm nwskev tsim kho peb-filament(feem ntau ntawm 0° thiab ±60° kev taw qhia), tsim cov duab peb ceg uas muaj nyob hauv daim ntaub. Cov qauv geometric no ruaj khov dua, faib kev ntxhov siab kom sib npaug hauv ntau qhov kev taw qhia.
Qhov kev tsom mus rau kev lag luam tshiab tshaj plaws yog kev ntsuas qhov zoo no. Cov kev sim ua qauv tsis ntev los no tau qhia tias cov qauv tsim triaxial zoo dua qub.tsis kam rau kev rhuav, tiv taus kev tawg, thiab nqus tau kev cuam tshuamRau ACPs, qhov no txhais ncaj qha mus rau hauv:
- Kev Ruaj Ntseg Zoo Dua:Cov qauv triaxial txo qhov kev nthuav dav thiab kev cog lus ntawm thermal, tiv thaiv kev ua kom roj tsis zoo (waviness) ntawm cov chaw teeb tsa facade loj thiab ua kom ntseeg tau tias lub sijhawm ntev.
- Lub zog Shear thiab Tensile zoo tshaj plaws:Qhov kev faib tawm ntawm ntau txoj kev thauj khoom tso cai rau cov vaj huam sib luag kom tiv taus cov cua hlob dua, kev nyuaj siab ntawm lub tshuab, thiab kev tswj hwm kev ntxhov siab thaum lub sijhawm teeb tsa, pab txhawb rau kev nyab xeeb thiab kev ua haujlwm ntev ntawm lub tsev.
- Kev Cuam Tshuam Zoo Dua Rau Qhov Hnyav-rau-Lub Zog:Cov chaw tsim khoom tuaj yeem ua tiav cov kev ua tau zoo raws li lub hom phiaj nrog cov khoom siv tseem ceeb uas sib dua, ua tsaug rau qhov ua tau zoo ntawm triaxial scrim, txhawb nqa kev tsav tsheb ntawm kev lag luam mus rau cov khoom siv ruaj khov dua thiab yooj yim dua rau kev teeb tsa.
Cov txiaj ntsig ntawm kev tsim triaxial yog qhov siab tshaj plaws thaum siv nrog cov khoom siv zoo.Fiberglass tau ua pov thawj tias yog tus neeg sib tw zoo tagnrho vim nws lub zog tensile siab, tshuaj lom neeg tsis kam rau cov tub ntxhais resins, thiab tsawg kawg nkaus ncab. Lub cim tshiab ntawm fiberglass scrims tau raug tsim nrog qhov zoo tshaj plaws sizing thiab filament diameters los txhim kho kev sib raug zoo nrog cov ntawv ci txhuas thiab tub ntxhais matrix, tsim kom muaj cov qauv sib xyaw ua ke uas ua haujlwm ua ib chav tsev, kev ua haujlwm siab.
Qhov ua tau zoo ntawm triaxial scrim yog nyob ntawm qhov tseeb ntawm nws txoj kev tsim khoom. Kev tso cov filament sib xws, qhov loj ntawm lub qhov mesh, thiab qhov hnyav tswj tau yog qhov tseem ceeb. Piv txwv li, ib qho scrim nrog lub grid zoo, xws li akev teeb tsa meej 12x12x12mm, ua kom cov resin ntws thiab lo rau zoo ib yam, tshem tawm cov qhov tsis muaj zog thiab lav qhov ua tau zoo kwv yees tau thoob plaws txhua square meter ntawm lub vaj huam sib luag. Qib kev ua kom raug no tso cai rau cov chaw tsim khoom ACP thawb cov ciam teb ntawm lawv cov khoom, ua rau cov tsev siab dua, muaj kev nyab xeeb dua, thiab muaj lub tsev zoo nkauj dua.

Yuav kom ua tau raws li cov qauv ntawm kev tsim khoom ACP niaj hnub no, cov ntaub ntawv zoo liTriaxial Fiberglass Scrim | 12x12x12mm rau Aluminium Foil Composite Reinforcementtau tsim los kom muaj kev ruaj khov zoo tshaj plaws thiab lub zog tensile. Tshawb nrhiav cov lus qhia txog kev siv tshuab kom pom tias nws tuaj yeem txhim kho koj qhov project tom ntej li cas.
