Kev sib piv thiab qhov sib txawv ntawm Carbon Fiber Sheets thiab PVC Sheets
Ntau tus neeg sib piv cov ntawv carbon fiber ntau thiab cov ntawv PVC, tsis paub yuav xaiv qhov twg. Lawv cia siab rau qhov kev tshuaj ntsuam piv rau ob hom ntaub ntawv no. Raws li cov chaw tsim khoom ntawm cov khoom siv fiber ntau, peb tau tsim ntau cov khoom siv carbon fiber ntau. Peb cov neeg siv khoom feem ntau muab cov lus tawm tswv yim raws li lawv qhov kev siv tiag tiag txog kev sib piv ntawm cov ntawv carbon fiber ntau thiab cov ntawv PVC. Hauv tsab xov xwm no, peb npaj los muab cov phiaj xwm sib piv uas peb vam tias yuav pab tau.
Cov ntawv carbon fiber ntau yog tsim los ntawm cov khoom siv carbon fiber prepreg, uas yog txheej txheej thiab tom qab ntawd kho ntawm qhov kub thiab txias los tsim cov khoom kawg. Txhawm rau kom ntseeg tau tias qhov ua tau zoo ntawm cov nplooj ntawv carbon fiber ntau, nws yog ib qho tseem ceeb uas yuav tsum tau them sai sai rau lub kaum sab xis ntawm cov txheej txheem thaum lub sij hawm stacking txheej txheem, uas txhim kho lub zog thiab shear tsis kam ntawm cov nplooj ntawv. Hauv qhov sib piv, cov ntawv PVC yog tsim los ntawm cov khoom siv raw PVC hauv cov qauv honeycomb, uas ua rau muaj qhov sib txawv tseem ceeb hauv cov khoom siv raw thiab cov txheej txheem tsim khoom.
Cia peb pib nrog cov ntawv carbon fiber. Lawv tau ua tiav los ntawm cov pa roj carbon fiber ntau uas muaj ntau dua 90% carbon cov ntsiab lus fused nrog cob. Qhov kev sib xyaw ua ke no ua rau cov khoom sib xyaw tshiab nrog lub zog siab thiab cov qauv, muab cov txiaj ntsig zoo piv rau cov khoom siv hlau. Qhov ceev ntawm tag nrho cov pa roj carbon fiber prepreg yog nyob ib ncig ntawm 1.7 g / cm³, thiab nws lub zog tuaj yeem ncav cuag 3000 MPa, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau cov khoom ua tau zoo uas yuav tsum tau txo qhov hnyav.
Lub zog siab, lub teeb yuag, zoo heev acid thiab corrosion kuj, siab-kub kam rau ua, tsis tshua muaj thermal expansion coefficient, thiab zoo X-ray permeability ua rau cov pa roj carbon fiber ntau daim ntawv thov txawm tias piv rau cov ntawv hlau. Lawv muaj kev lag luam muaj zog hauv kev lag luam xws li aerospace thiab chaw kho mob.
Ntawm qhov tod tes, PVC ntawv yog tsim los ntawm PVC, ib hom khoom yas uas muaj cov polyvinyl chloride resin, plasticizers, thiab stabilizers. Thaum cov khoom siv no muaj lub zog muaj zog, nws tuaj yeem tso cov tshuaj lom ntawm qhov kub thiab txias. Kev siv PVC feem ntau yog nyob rau hauv cov khoom qis, xws li cov ntawv txheeb, cov khoom ua si, thiab cov ntawv sau, qhov chaw ua haujlwm tsis muaj qhov kub thiab txias.
Piv txwv li, qhov zoo ntawm cov nplooj ntawv carbon fiber yog nyob rau hauv lawv lub zog siab, kev ruaj ntseg zoo, kev ua haujlwm siab kub, kev tiv thaiv corrosion, puas-resistant, thiab zoo heev X-ray permeability. Txawm li cas los xij, lawv muaj qhov tsis zoo, suav nrog kev ua haujlwm tsawg, yuav tsum tau ua tiav phau ntawv ntau lawm, thiab cov nqi siab dua.
Hauv qhov sib piv, cov ntawv PVC muaj cov khoom siv tsis muaj zog thiab qis dua qhov kub thiab txias dua li cov ntawv carbon fiber, tab sis lawv tuaj ntawm tus nqi qis dua, ua rau lawv muaj txiaj ntsig zoo rau kev lag luam. Cov txheej txheem tsim khoom rau PVC yog tsim tau zoo, tso cai rau kev tsim khoom sai ntawm tus nqi qis, ua kom yooj yim rau kev faib khoom ntau dua. Cov ntawv PVC feem ntau yog siv rau hauv ntau daim ntawv thov ntim, thaum cov nplooj ntawv carbon fiber ntau muaj nyob rau hauv high-end industries, qhia tias lawv daim ntawv thov ib puag ncig txawv heev.
