Fiberglass muaj ntau yam zoo xws li lub zog siab thiab lub teeb yuag, corrosion tsis kam, thiab hluav taws xob rwb thaiv tsev zoo. Nws yog ib qho ntawm cov khoom siv sib xyaw ua ke. Nyob rau tib lub sijhawm, Suav kuj yog lub ntiaj teb cov neeg tsim khoom loj tshaj plaws ntawm cov fiberglass.
1. Dab tsi yog fiberglass?
Fiberglass yog ib qho khoom siv tsis yog xim hlau nrog kev ua tau zoo heev. Nws yog cov ntxhia uas muaj cov ntxhia nrog Silica yog cov khoom siv raw ntau, ntxiv cov hlau tshwj xeeb xaim roj nyoos. Tom qab sib tov tusyees, nws tau melted ntawm qhov kub thiab txias, thiab lub khob molten ntws los ntawm kev xau nozzle. , raws li kev txiav txim ntawm kev siv ceev ceev rub tawm, nws yog kos thiab nrawm nroos thiab muaj kev sib txawv rau hauv cov fibers tsis tseem ceeb.
Lub taub ntawm fiberglass monofilament ranges los ntawm ob peb microns rau nees nkaum microns, uas yog sib npaug rau 1 / 20-1 / 5 ntawm plaub hau. Txhua ntu ntawm fiber ntau cov strands yog tsim ntawm ntau pua lossis txawm tias ntau txhiab ntawm monofilaments.
Cov yam yooj yim ntawm fiberglass:
Cov tsos yog ib qho cylindrical puab nrog txoj kev ncaj qha, cov ntoo khaub lig yog lub voj voog uas ua tiav muaj lub zog thauj khoom muaj peev xwm; Cov roj thiab kua dhau mus tiv taus me, tab sis cov npoo nruj ua rau lub zog fiber ntau, uas tsis muaj txiaj ntsig zoo rau kev ua ke nrog Resin; Cov ceev ceev feem ntau nyob rau hauv 2.50-2.70 g / cm3, feem ntau yog nyob ntawm cov iav muaj pes tsawg leeg; lub zog tensile siab dua lwm cov ntuj fibers thiab cov hluavtaws; Cov khoom siv loj, nws elongation ntawm kev so yog qhov tsawg heev; Cov dej tsis kam thiab acid tsis zoo yog qhov zoo dua, thaum alkali tsis yog tsawg. Qhov txawv.
2. Kev faib tawm ntawmtxoj plaublub khob
Los ntawm kev faib tawm ntev, nws tuaj yeem muab faib ua cov iav fiber ntau, luv luv fiberglassy (lft).
3. Kev thov ntawm fiberglass
Cov fiberglass muaj lub zog siab tensile lub zog, muaj cov modulus siab ntawm elasticity, tsis yog-flammability, tshuaj tsis kam, cov dej nqus dej tsawg, thiab kev ua haujlwm zoo. , dav siv nyob rau hauv ntau daim teb.
Cov ntaub ntawv siv txawv teb chaws tsis tau muab faib ua kom cov khoom siv thermograstcing, cov khoom siv uas txhawb nqa cov khoom siv rau 70-75%, fiberglass textile textile cov ntaub ntawv cov ntaub ntawv rau 25-30%. Los ntawm qhov kev pom ntawm DownStream thov kom tau txais kev thov rau txog li ntawm 38% (suav nrog cov khoom siv dej hiav txwv, thiab lwm yam.
Txhawm rau kom suav cov ntawv thov ntawm fiberglass feem ntau suav nrog kev thauj mus los, kev lag luam hauv tsev, kev lag luam hluav taws xob, kev cai lij choj petisure thiab kev tiv thaiv kev tiv thaiv tshuab.
