Dab tsi yog qhov cuam tshuam ntawm cov tshuaj ruaj khov ntawm fiberglass ntawm qhov kav ntev ntawm fiberglass nuv ntses nkoj?
Zuag qhia tag nrho kev ua tau zoo ntawmfiberglassFeem ntau txiav txim siab los ntawm nws cov tshuaj intrinsic muaj pes tsawg leeg thiab cuam tshuam los ntawm txoj kev tsim khoom, txheej txheem kev kho cua sov, thiab cov tshuaj impregnating nto. Ntawm ntau qhov kev ua tau zoo, cov khoom siv hluav taws xob yog qhov txiaj ntsig tseem ceeb uas nws txawv ntawm ntau lwm cov ntaub ntawv, tshwj xeeb tshaj yog hauv kev siv hluav taws xob rwb thaiv tsev.
Core Electrical Performance Yam ntxwv
1. High Specific Resistivity:
Cov iav fiber ntau muaj qhov ntim siab heev (kev tiv thaiv tshwj xeeb). Qhov no txhais tau hais tias nws muaj peev xwm muaj zog heev los cuam tshuam qhov kev nkag mus ntawm tam sim no, nthuav tawm tsis zoo conductivity.
Cov cuab yeej rwb thaiv tsev zoo no ua rau nws muaj txiaj ntsig zoo tiv thaiv tam sim no, ua kom muaj kev nyab xeeb ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
2. Tsis tshua muaj Dielectric Constant:
Cov iav fiber ntau muaj qhov dielectric tsis tu ncua.
Lub dielectric qhov tsis tu ncua yog qhov qhia txog cov khoom muaj peev xwm khaws cov hluav taws xob hauv hluav taws xob. Qhov qis dielectric qhov tsis tu ncua txhais tau hais tias cov khoom siv tau qis dua polarization nyob rau hauv alternating hluav taws xob teb (xws li nyob rau hauv siab - zaus circuits), ua rau lub zog poob tsawg, zoo dua cov teeb liab kis tau tus mob, thiab txo cov hluav taws xob tiam.
Qhov kev txiav txim siab hauv cov khoom hluav taws xob
Tshuaj muaj pes tsawg leeg, tshwj xeeb tshaj yog cov ntsiab lus alkali.
Cov ntsiab lus tseem ceeb: Qhov tseem ceeb tshaj plaws thiab qhov tseem ceeb ntawm kev txiav txim siab ntawm cov khoom siv hluav taws xob ntawm iav fiber ntau, tshwj xeeb tshaj yog nws cov rwb thaiv tsev tsis kam thiab dielectric poob, yog nws cov tshuaj muaj pes tsawg leeg.
Cov neeg ua si tseem ceeb: Alkali hlau oxides (xws li Na₂O, K₂O): Cov ntsiab lus ntawm alkali hlau oxides hauv cov iav muaj feem cuam tshuam rau cov khoom hluav taws xob. Cov alkali hlau ions (Na⁺, K⁺) muaj kev txav mus los (conductivity) nyob rau hauv ib qho hluav taws xob teb, uas yuav:
Tseem ceeb txo qhov ntim resistivity (tshwj xeeb tsis kam) ntawm cov khoom, tsis muaj zog rwb thaiv tsev kev ua tau zoo.
Ua kom dielectric poob, ua rau muaj cua sov ntau dua thaum ua haujlwm ntawm cov khoom siv hluav taws xob siab lossis cov hluav taws xob siab, txo qis kev ua haujlwm, thiab cov khoom siv yooj yim dua.
Qhov zoo ntawm alkali-dawb iav fiber ntau: Pom qhov tsis zoo ntawm alkali hlau ions, alkali-dawb iav fiber (feem ntau xa mus rau E- iav fiber) tau tsim tshwj xeeb. Nws cov yam ntxwv tseem ceeb yog kev tswj hwm nruj ntawm alkali hlau oxide cov ntsiab lus ntawm qib qis heev (feem ntau tsawg dua 0.8%).
Kev Txhim Kho Kev Ua Haujlwm: Cov ntsiab lus tsis tshua muaj alkali ntawm alkali-dawb iav fiber ntau muab rau nws:
Cov rwb thaiv tsev zoo heev (siab tshwj xeeb tsis kam), muaj peev xwm tiv taus siab voltage yam tsis muaj kev puas tsuaj.
Tsis tshua muaj dielectric tsis tu ncua thiab dielectric poob, tshwj xeeb tshaj yog tsim rau kev ua haujlwm hauv siab - zaus, siab -voltage ib puag ncig, kom ntseeg tau cov teeb liab ruaj khov thiab tsis muaj zog poob.
Zoo arc kuj.
Daim Ntawv Thov Cheeb Tsam: Cov khoom siv tseem ceeb rau kev lag luam hluav taws xob thiab lub cev muaj zog
Tau txais txiaj ntsig los ntawm nws cov khoom siv hluav taws xob zoo tshaj plaws (siab tshwj xeeb tsis kam, tsis tshua muaj hluav taws xob tsis tu ncua / poob) thiab kub ua haujlwm thiab lub zog siv tshuab, alkali-cov khoom siv iav fiber ntau tau siv dav hauv cov khoom hauv qab no:
Printed Circuit Board (PCB) Substrates: Xws li hluav taws xob- qib iav fiber ntau daim ntaub (electronic daim ntaub), nws yog ib qho tseem ceeb cov khoom siv hauv kev tsim cov tooj liab- clad laminates (CCL) thiab PCB kawg, muab kev txhawb nqa lub cev thiab hluav taws xob rwb thaiv tsev rau cov khoom siv hluav taws xob niaj hnub no.
Lub cev muaj zog thiab lub tshuab hluav taws xob rwb thaiv tsev: Siv los ua insulating qhov wedges, khi tapes, bushings, mica reinforcement cov ntaub ntawv, thiab lwm yam, rau lub cev muaj zog stators thiab rotor coils, ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov motors nyob rau hauv qhov kub thiab txias, siab, thiab kev kub ceev. • High-cov khoom siv hluav taws xob hluav taws xob rwb thaiv tsev: Siv rau cov khoom siv hluav taws xob insulating, insulating rods, insulating khi rods, thiab lwm yam khoom hauv transformers, switchgear, thiab instrument transformers.
Hlau thiab cable rwb thaiv tsev: Siv los ua ib qho insulating lossis reinforcing txheej rau cov xov hlau thiab cables.
High- khoom siv sib txuas lus zaus: Nws qhov tsis tshua muaj dielectric poob ua rau nws haum rau cov kav hlau txais xov radomes, radomes, siab - zaus Circuit Court boards, thiab lwm yam.
Cov ntsiab lus
Fiberglass, tshwj xeeb tshaj yog alkali-dawb iav fiber ntau (E- iav) nrog nruj tswj alkali hlau oxide cov ntsiab lus, tau dhau los ua ib qho tseem ceeb ntawm insulating cov ntaub ntawv nyob rau hauv niaj hnub hluav taws xob, hluav taws xob, thiab lub cev muaj zog industries vim nws tshwj xeeb ua ke ntawm siab resistivity, tsis tshua muaj dielectric tsis tu ncua, thiab tsawg dielectric poob. Nws cov hluav taws xob rwb thaiv tsev zoo heev, lub zog txhua yam, thiab thermal stability muab cov khoom siv tseem ceeb rau kev nyab xeeb, ua haujlwm zoo, thiab kev ua haujlwm me me ntawm kev xa hluav taws xob, khoom siv hluav taws xob, thiab lub cev muaj zog.
