Qhov sib txawv ntawm Fiberglass thiab Carbon Fiber
Cov iav fiber ntau thiab carbon fiber yog ob feem ntau pom fiber ntau cov ntaub ntawv sib xyaw, tab sis lawv muaj qhov sib txawv tseem ceeb ntawm cov khoom siv kho tshuab thiab kev ua haujlwm. Cia kuv piav qhia rau koj ib leeg hauv qab no:
1. Cov khoom sib txawv
Nws yog qhov tseeb tias fiberglass thiab carbon fiber muaj ntau yam sib xyaw los ntawm lub npe tab sis koj puas paub cov ntsiab lus ntawm nws?
Cov iav fiber ntau yog cov khoom siv fiber ntau tsim los ntawm cov iav fiber ntau los yog ntu ntu ntu; thaum carbon fiber yog cov khoom siv fiber ntau ntxiv los ntawm cov khoom siv fiber ntau, raws li tau piav qhia hauv qab no.
Cov iav fiber ntau (fiberglass) yog ib qho zoo heev inorganic non-metallic khoom nrog ntau yam khoom. Nws qhov zoo muaj xws li rwb thaiv tsev zoo, muaj zog kub tsis kam, zoo corrosion kuj, siab mechanical zog thiab lwm yam. Txawm li cas los xij, nws qhov tsis zoo muaj xws li brittleness thiab hnav tsis zoo. Nws cov khoom tseem ceeb yog silicon dioxide, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, thiab lwm yam. Raws li cov ntsiab lus alkali hauv iav, nws tuaj yeem muab faib ua alkali dawb iav fiber, nruab nrab alkali iav fiber ntau, thiab siab alkali. iav fiber. Cov iav fiber ntau feem ntau yog siv los ua cov khoom siv ntxiv hauv cov khoom sib xyaw, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam kev lag luam hauv lub teb chaws.Cov iav fibers tuaj yeem muab faib ua cov fibers txuas ntxiv, ruaj khov ntev fibers, thiab iav ntaub plaub raws li kev lag luam. lawv morphology thiab ntev; Raws li cov iav muaj pes tsawg leeg, nws tuaj yeem muab faib ua alkali dawb, tshuaj tiv thaiv, siab alkali, nruab nrab alkali, siab zog, siab elastic modulus, thiab alkali resistant (alkali resistant) iav fibers
Cov pa roj carbon fiber ntau yog ib yam tshiab ntawm cov khoom siv fiber ntau nrog lub zog siab thiab siab modulus uas fibers nrog cov ntsiab lus carbon ntau dua 95 feem pua. Nws yog cov khoom siv microcrystalline graphite tau los ntawm stacking organic fibers xws li flake graphite microcrystals raws axial kev taw qhia ntawm cov fibers thiab undergoing carbonization thiab graphitization kho. Cov pa roj carbon fiber ntau yog sib dua li aluminium hlau, tab sis tawv dua li hlau. Nws kuj muaj kev tiv thaiv corrosion thiab siab modulus yam ntxwv, ua rau nws yog ib yam khoom tseem ceeb hauv kev tiv thaiv lub teb chaws, kev lag luam tub rog, thiab kev siv pej xeem. Nws tsis tsuas yog muaj cov yam ntxwv ntawm cov khoom siv carbon, tab sis kuj muaj qhov yooj yim thiab kev ua tiav ntawm cov khoom siv fiber ntau, ua rau nws yog ib tiam tshiab ntawm kev txhawb nqa fibers.
2. Cov khoom sib txawv ntawm lub cev
Cov pa roj carbon fiber muaj ntau yam zoo heev, xws li siab axial zog thiab modulus, tsis tshua muaj ceev, siab tshwj xeeb kev ua tau zoo, tsis muaj creep, super kub kuj nyob rau hauv tsis oxidizing ib puag ncig, zoo qaug zog kuj, tshwj xeeb kub thiab conductivity ntawm nonmetal thiab hlau, me me coefficient ntawm thermal expansion thiab anisotropy, zoo corrosion kuj, thiab zoo X-ray kis tau tus mob. Zoo conductivity, thermal conductivity, electromagnetic shielding, thiab lwm yam, thaum iav fiber muaj kuj tsis tshua muaj zog thiab nruj, tab sis muaj zoo heev rwb thaiv tsev thiab corrosion kuj.
Cov pa roj carbon fiber muaj cov conductivity zoo, yog li nws cov rwb thaiv tsev tsis zoo. Thaum cov pa roj carbon fiber ntsib qhov chaw ntub dej lossis cov kua dej, lawv cov hluav taws xob tiv thaiv yuav txo qis, ua rau txo qis hauv rwb thaiv tsev. Yog li ntawd, hauv cov ntawv thov uas xav tau kev rwb thaiv tsev siab, iav fiber ntau feem ntau yog xaiv los ntawm carbon fiber.
Tsis tas li ntawd, carbon fibers yuav raug cuam tshuam los ntawm corrosion nyob rau hauv tej qhov chaw ib puag ncig, xws li kub kub los yog muaj zog acidic thiab alkaline ib puag ncig, qhov twg carbon fibers yuav undergo oxidation los yog tshuaj tiv thaiv thiab poob ib co ntawm lawv cov kev ua tau zoo. Fiberglass muaj zoo heev corrosion kuj thiab yog haum rau ib puag ncig nrog corrosive media.
3. Cov ntawv thov sib txawv
Vim nws lub zog siab thiab nruj, carbon fiber feem ntau yog siv rau hauv kev tsim cov khoom siv high-end, xws li aerospace, tsheb, thiab cov khoom ua si. Fiberglass feem ntau yog siv rau hauv cov khoom lag luam xws li architecture, tsheb, nkoj, thiab cua tsim hluav taws xob, xws li cov ntaub ntawv rwb thaiv tsev, cov ntaub ntawv rwb thaiv tsev, cov khoom siv hluav taws xob, cov khoom cement, thiab lwm yam.
4. Tus nqi sib txawv
Tus nqi ntawm cov pa roj carbon fiber ntau ntau dua li cov fiberglass feem ntau vim yog cov khoom tsim tau tsawg ntawm carbon fiber. Cov chaw nkag rau kev ua tiav cov pa roj carbon fiber ntau yog kim.
