Daim Ntawv Thov Ciam Teb: Vim li cas Ob Cov Khoom Siv no tau muab piv rau hauv Engineering Projects
Nyob rau hauv lub tsheb lub cev tsim, modular tsev vaj huam sib luag, cov khoom enclosures, thiab tiv thaiv npog, engineers feem ntau piv fiberglass ntawv thiab polycarbonate ntawv vim hais tias ob qho tib si yog siv raws li cov ntaub ntawv sab nrauv tab sis teb txawv load, cuam tshuam, kub, thiab tshuaj lom neeg raug.
Cov ntawv fiberglass yog iav fiber ntau-txhim kho cov thermoset laminate uas nqa cov khoom siv los ntawm cov tes hauj lwm fiber ntau kos hauv polyester, yas ester, lossis epoxy resin. Cov ntawv polycarbonate yog ib lub phaj thermoplastic uas ua los ntawm bisphenol-Ib cov saw hlau raws li polymer uas deform nyob rau hauv kev cuam tshuam thiab rov zoo li qub los ntawm cov saw hlau molecular.
Qhov kev txiav txim siab xaiv feem ntau yog txuas mus rau seb lub vaj huam sib luag yuav tsum nqa cov qauv ua haujlwm (cov ntaub ntawv fiberglass) los yog nqus cov cuam tshuam thaum tuav cov pob tshab (polycarbonate case).
Cov qauv txheej txheem sib txawv: Fiber Load Transfer vs Molecular Deformation
Fiberglass daim ntawv hloov cov neeg kho tshuab kev ntxhov siab los ntawm cov txheej txheem fiber ntau. Thaum lub sij hawm khoov, iav fibers nyob rau hauv cov txheej laminate txheej nqa tensile thiab compressive zog, thaum resin hloov shear ntawm txheej. Cov ntawv tuab tuab li ntawm 1 hli mus rau 8 hli nyob ntawm laminate stacking ceev.
Polycarbonate ntawv tsis muaj fiber ntau reinforcement. Hloov chaw, nws tiv thaiv kev cuam tshuam los ntawm kev sib hloov ntawm cov saw hlau thiab cov yas deformation. Standard industrial thickness ranges ntawm 2 hli mus rau 12 hli, qhov twg cov nplooj ntawv tuab tuaj yeem ua rau muaj kev cuam tshuam tsis zoo tab sis txo qhov kev hloov pauv thaum lub caij txias.
Fiberglass Ntawv
Load faib los ntawm fiber ntau orientation + resin bonding
Polycarbonate Sheet
Load absorbed los ntawm yas deformation ntawm polymer chains
Mechanical Cwj Pwm Nyob rau hauv Load thiab Temperature Conditions
Fiberglass daim ntawv tuav nruj raws li qhov nruam loading, feem ntau yog siv nyob rau hauv panels spanning 1-3 meters thaum bonded rau hlau los yog honeycomb cores. Txawm li cas los xij, qhov cuam tshuam ntawm ntug tuaj yeem pib microcracks ntawm cov txheej fiber ntau, tshwj xeeb tshaj yog thaum cov ntsiab lus ntawm cov resin tsis sib npaug los yog kho tsis tiav.
Polycarbonate ntawv tiv thaiv qhov cuam tshuam tam sim ntawd xws li cov khoom poob lossis cov cuab yeej ntaus, tab sis nyob rau hauv kev txhawb nqa siab tshaj qhov kev ntxhov siab, nws tuaj yeem deform mus tas li. Ntawm qhov kub siab tshaj li ntawm 110-120 degree, polycarbonate pib mos thiab poob qhov ruaj khov.
Fiberglass daim ntawv coj cwj pwm nyob ntawm resin system:
Environmental Resistance: UV, noo noo, thiab tshuaj lom neeg
Daim ntawv fiberglass siv cov resin matrix uas thaiv cov dej nkag, tab sis ntev - UV raug tuaj yeem degrade nto resin, ua rau chalking los yog deg microcracking yog tias tsis muaj gel txheej txheej. Hauv kev kho cov dej khib nyiab los yog cov tsheb thauj khoom sab nraum zoov, gel tsho tuab (feem ntau 0.3-0.6 hli) yog siv los ua kom UV degradation qeeb.
Polycarbonate ntawv xa cov teeb pom kev zoo tab sis muaj kev cuam tshuam rau UV hluav taws xob yam tsis muaj kev tiv thaiv txheej. Hauv kev teeb tsa sab nraum zoov xws li cov ntaub thaiv kev nyab xeeb lossis cov glazing vaj huam sib luag, UV- cov txheej txheem ruaj khov yog siv los txo cov xim daj los ntawm cov saw hlau oxidation.
Chemical resistance txawv:
Kev tsim khoom thiab kev coj tus cwj pwm hauv cov kab ntau lawm
Fiberglass daim ntawv ntau lawm muaj resin impregnation ntawm iav fiber mats ua raws li los ntawm curing nyob rau hauv kev tswj kub. Nruam lamination kab tsim cov nplooj ntawv nrog tuab kam rau ua feem ntau tswj tsis pub dhau ± 0.2-0.5 hli nyob ntawm kab ceev thiab resin viscosity.
Polycarbonate ntawv yog tsim los ntawm extrusion lossis txhaj tshuaj-raws li daim ntawv sau. Tom qab extrusion, nplooj ntawv yog txias los ntawm calibrated rollers los tswj cov kev ntxhov siab nyob rau hauv, uas ncaj qha cuam tshuam rau tawg tsis kam thaum tom qab khoov los yog txiav ua hauj lwm.
