Raws li cov duab thiab ntev, iav fiber tuaj yeem faib ua cov fiber ntau, tsau-ntev fiber ntau thiab cov ntaub plaub iav; Raws li iav muaj pes tsawg leeg, nws tuaj yeem faib ua cov tshuaj lom neeg, cov tshuaj lom neeg muaj zog, muaj zog tiv thaiv (alkali tsis kam) fiberglass, thiab lwm yam.
Cov khoom siv raw loj rau cov iav fiber ntau lawm Lwm tus yog thawj zaug ua rau molten iav rau iav lossis pas nrig nrog rau ntau txoj hauv kev los ua cov iav lossis pas nrig nrog txoj kab uas hla ntawm 3 mus rau 3 hli. 80μm nplua nuj heev. Lub infinitely ntev cov fibers kos los ntawm lub tshuab tshuab kos qauv ntawm platinum cov daim hlau tau hu ua cov iav txuas txuas ntxiv, feem ntau yog hu ua ntev fibers. Cov khoom ua tsis tau zoo ua los ntawm cov txiv ntoo lossis cov huab cua ntws, hu ua tsau-ntev iav fibers, feem ntau hu ua luv luv fibers
Cov iav fibers tau faib rau hauv cov qib sib txawv raws li lawv cov lus sib xyaw, cov khoom siv thiab siv. Raws li cov kev cai ntawm qib theem, E-Qib iav Fiber ntau yog siv dav thiab dav siv hauv cov khoom siv hluav taws xob; S-qib yog fiber ntau.
Cov iav siv nyob rau hauv kev tsim cov fiberglass sib txawv yog txawv ntawm cov iav siv hauv lwm cov khoom siv iav. Feem ntau, cov iav muaj pes tsawg leeg rau cov fibers uas tau ua lag luam yog raws li hauv qab no:
Siab zog thiab cov ntsiab lus siab modulus fiberglass
Nws yog tus cwj pwm los ntawm lub zog siab thiab cov modulus siab. Nws ib lub zog fiber ntau yog 2800MPA, uas yog kwv yees li 25% siab tshaj li ntawm cov iav alkali yog 86000mpa, uas yog siab dua e-iav fiber ntau. Daim FRP cov khoom tsim tawm nrog lawv feem ntau siv hauv kev lag luam tub rog, are-ceev kev tsheb ciav hlau, cua fais fab, cov khoom siv cua daj cua dub thiab cov khoom siv kis las.
Ar fiberglass
Kuj tseem hu ua Alkali-resistant iav fiber ntau, alkali-resistant iav fiber ntau, thiab ib qho zoo tshaj plaws rau cov khoom siv hlau thiab asbestos nyob rau hauv tsis-bear-bearing coulle. The characteristics of alkali-resistant glass fiber are good alkali resistance, can effectively resist the erosion of high alkali substances in cement, strong gripping force, high elastic modulus, impact resistance, tensile and bending strength, non-flammable, frost-resistant, temperature-resistant , strong humidity change ability, excellent crack resistance and impermeability, strong designability, easy molding, etc., alkali-resistant Iav Fiber yog hom tshiab ntawm ntsuab thiab ib puag ncig tus phooj ywg cuam tshuam dav siv hauv kev ua tau zoo (xis mas) ua kom zoo nkauj.
D iav
Kuj tseem hu ua daim iav qis, nws yog siv los ua cov iav dielectric qis nrog lub zog dielectric zoo.
Ntxiv nrog rau cov iav qab zib saum toj no, cov iav dawb alkali-dawb, yog li nws cov hluav taws xob ib puag ncig thiab cov khoom siv mechanies zoo ib yam li cov tshuaj e iav. Tsis tas li ntawd, muaj lub khob fiber nrog ob lub iav muaj pes tsawg leeg, uas tau siv rau hauv cov ntaub plaub iav, thiab nws tseem hais tias muaj peev xwm rau cov khoom siv fiberglass ntxiv. Ib qho ntxiv, muaj fluorine-dawb iav fiber ntau, uas yog kev txhim kho cov kua dawb fiber ntau tsim rau kev tiv thaiv ib puag ncig.

Tsis tas li ntawd, muaj lub khob fiber nrog ob lub iav muaj pes tsawg leeg, uas tau siv rau hauv cov ntaub plaub iav, thiab nws tseem hais tias muaj peev xwm rau cov khoom siv fiberglass ntxiv. Ib qho ntxiv, muaj fluorine-dawb iav fiber ntau, uas yog kev txhim kho cov kua dawb fiber ntau tsim rau kev tiv thaiv ib puag ncig.
Koj tuaj yeem faib cov fiberglass ua ntau pawg, nyob ntawm seb cov ntaub ntawv raw siv thiab lawv cov proportions.
Nov yog 7 yam sib txawv ntawm cov fiberglass thiab lawv cov ntawv thov hauv cov khoom txhua hnub:
Alkali iav (A-iav)
Dej qab zib iav lossis dej qab zib kua. Nws yog qhov dav siv fiberglass hom. Alkali iav iav nyiaj rau li 90% ntawm txhua lub tshuab tsim khoom. Nws yog hom feem ntau thiab yog siv los ua cov iav ntim, xws li cov kaus poom thiab fwj rau zaub mov thiab dej haus, thiab iav qhov rai.
Ci tais diav ua los ntawm tempered dej qab zib kua qaub iav kuj yog ib qho zoo meej ntawm lub khob. Nws muaj nqis, siab heev, thiab cov tawv. Ib-hom khob iav tuaj yeem rov qab tau rov qab thiab rov muag dua ntau zaus thiab yog cov iav fiber ntau rau iav ua dua tshiab.
Alkali-resistant iav ae-iav lossis ar-iav
AE lossis AR khob sawv rau Alkali Resistant iav, uas yog siv tshwj xeeb rau pob zeb ua. Nws yog cov khoom siv sib xyaw ua ke ntawm zirconia.
Qhov kev sib ntxiv ntawm zirconia, ib qho nyuaj, kub-resistant ntxhia, ua rau cov fiberglass haum rau siv hauv pob zeb. AR-iav tiv thaiv cov pob zeb ua kom tawg los ntawm kev muab lub zog thiab hloov tau yooj yim. Tsis tas li, tsis zoo li cov hlau, nws tsis muaj xeb yooj yim.
Tshuaj Iav
C-iav lossis cov iav tshuaj yog siv los ua cov ntaub so saum npoo rau cov roj sab nraud ntawm laminates rau cov kav dej thiab ntim rau khaws cia dej thiab tshuaj. Vim yog cov siab ntawm cov calcium borosilicate siv nyob rau hauv lub khob tsim txheej txheem, nws ua kom pom qhov siab tshaj plaws hauv cov tshuaj uas muaj teeb meem.
C-iav tswj cov tshuaj thiab cov qauv sib npaug nyob rau hauv txhua qhov chaw thiab muaj kev ncaj ncees rau cov tshuaj lom alkaline.
Dielectric iav
Dielectric iav (d-iav) cov khoom siv tau siv hauv cov khoom siv, cantace, thiab zoo li cas. Nws tseem yog qhov zoo tshaj plaws ntawm cov fiberglass vim nws cov dielectric tas li. Qhov no yog vim muaj lub boron trioxide nyob rau hauv nws muaj pes tsawg leeg.
Hauv iav
E-iav lossis e-fiberglass daim ntaub yog ib tus qauv kev lag luam uas muaj kev sib npaug ntawm kev ua tau zoo thiab raug nqi. Nws yog ib lub teeb yuag sib xyaw nrog cov ntawv thov hauv Aerospace, tubrog nkoj thiab kev muaj chaw. E-iav 'cov khoom uas ua rau muaj kev txhawb nqa fiber ntau tau ua rau nws darling ntawm cov khoom lag luam xws li cov nroj tsuag, cov nkoj, thiab cov nkoj.
E-iav hauv iav wool fibers tuaj yeem ua rau cov duab lossis qhov loj me uas siv cov txheej txheem tsim khoom yooj yim. Nyob rau hauv pre-ntau lawm, cov khoom ntawm e-iav fiber ua kom huv thiab nyab xeeb rau kev ua haujlwm nrog.
Cov Qauv Ik
Txheej txheem.Cov duab (s iav) yog paub rau nws cov khoom siv neeg. Cov npe lag luam R-iav, S-iav thiab T-iav tag nrho cov xa mus rau tib lub fiberglass. Piv nrog e-iav fiber ntau, nws muaj lub zog ntau dua thiab cov qauv hloov kho. Cov fiberglass yog tsim los siv rau hauv kev tiv thaiv thiab aerospace kev lag luam.
Nws kuj yog siv nyob rau hauv rigid ballistic armor thov. Vim tias cov iav fiber ntau yog cov kev ua tau zoo, nws tsuas yog siv nyob rau hauv kev lag luam tshwj xeeb nrog kev ua haujlwm tsawg. Nws kuj txhais tau tias S-iav tuaj yeem kim.
Advantex fiberglass
Cov tshuab fiberglass tau siv dav hauv cov roj, roj thiab mining kev lag luam, nrog rau hauv cov nroj tsuag hluav taws xob thiab cov tshuaj lim dej (dej phwj tuaj). Nws muab cov khoom siv hluav taws xob thiab hluav taws xob ntawm e-iav nrog cov acid corrosion tsis kam ntawm e, c, r hom iav fibers. Nws yog siv nyob rau hauv ib cheeb tsam uas cov qauv muaj kev cuam tshuam ntau rau kev xeb.
