Cov khoom tseem ceeb sib txawv ntawm fiberglass daim ntaub thiab iav
Fiberglass daim phiaj daim ntaub yog ib qho uas tsis yog-twisted roving dawb weave ntaub, uas yog ib qho tseem ceeb hauv paus ntaub ntawv rau tes nteg-up FRP. Lub zog ntawm daim ntaub square feem ntau yog nyob rau hauv warp thiab weft cov lus qhia ntawm cov ntaub. Rau lub sijhawm uas xav tau siab warp lossis weft lub zog, nws tuaj yeem ua rau hauv cov ntaub unidirectional. Nws tuaj yeem npaj ntau qhov kev sib tw untwisted hauv warp lossis weft cov lus qhia. Warp rau ntaub, ib qho weft rau ntaub.
Fiberglass ntaubyog tsim los ntawm kev kos iav rau hauv cov iav filaments zoo heev, thiab cov iav filaments nyob rau lub sijhawm no muaj qhov yooj yim. Cov iav filaments yog spun rau hauv cov xov paj, thiab tom qab ntawd dhau los ntawm ib lub loom mus rau hauv cov ntaub iav fiber ntau. Vim tias cov iav filament yog nyias nyias thiab thaj chaw saum npoo ntawm ib chav tsev loj, qhov kub tsis kam ua haujlwm raug txo. Nws zoo li melting ib tug nyias tooj liab hlau nrog ib tug tswm ciab. Tab sis iav tsis hlawv. Qhov hluav taws kub peb tuaj yeem pom yog qhov tseeb cov khoom siv cob coated rau ntawm daim ntaub iav fiber ntau, los yog cov impurities txuas ntxiv txhawm rau txhim kho kev ua haujlwm ntawm cov iav fiber ntau. Ntshiab fiberglass daim ntaub los yog coated nrog ib co high-temperature-resistant coatings yuav siv tau los ua cov khoom xws li hluav taws kub-resistant khaub ncaws, hnab looj tes tiv thaiv hluav taws, thiab hluav taws kub-resistant pam. Txawm li cas los xij, yog tias nws nkag mus rau hauv cov tawv nqaij ncaj qha, cov fibers tawg yuav ua rau tawv nqaij ntau dua thiab khaus khaus heev.
Fiberglass daim ntaub feem ntau yog siv rau hauv tes nteg txheej txheem, thiab fiberglass reinforced cov ntaub ntawv daim phiaj yog tsuas yog siv nyob rau hauv lub nkoj hulls, cia tso tsheb hlau luam, txias yees, nkoj, tsheb, tso tsheb hlau luam, thiab lub tsev cov ntaub ntawv. Fiberglass daim ntaub yog tsuas yog siv nyob rau hauv kev lag luam: tshav kub rwb thaiv tsev, hluav taws kub tiv thaiv, nplaim retardant. Cov khoom siv nqus cua kub ntau thaum nws hlawv los ntawm nplaim taws thiab tuaj yeem tiv thaiv cov nplaim taws los ntawm kev sib cais thiab cais cov huab cua.
1. Raws li cov muaj pes tsawg leeg: feem ntau nruab nrab-alkali, tsis-alkali, high-alkali (kom cais cov muaj pes tsawg leeg ntawm alkali hlau oxides hauv iav fiber), tau kawg, kuj muaj kev faib tawm los ntawm lwm cov khoom xyaw, tab sis muaj ntau ntau yam. , tsis yog ib tug los ntawm ib tug enumerate.
2. Raws li cov txheej txheem tsim khoom: crucible hlau kos duab thiab pas dej ua ke kiln hlau kos duab.
3. Raws li ntau yam: muaj ply yarn, direct yarn, jet yarn, etc.
Tsis tas li ntawd, lawv txawv los ntawm ib txoj kab uas hla fiber ntau, TEX tooj, twist, thiab sizing hom. Kev faib tawm ntawm cov ntaub iav fiber ntau zoo ib yam li kev faib cov xov paj fiber ntau. Ntxiv rau qhov saum toj no, nws kuj muaj xws li: txoj kev weaving, gram hnyav, dav, thiab lwm yam.
Cov khoom tseem ceeb sib txawv ntawmfiberglass ntaubthiab iav: Cov khoom siv tseem ceeb sib txawv ntawm cov iav fiber ntau thiab iav tsis loj, feem ntau yog vim muaj cov khoom siv sib txawv thaum lub sij hawm tsim khoom, yog li muaj qee qhov sib txawv hauv cov qauv. Cov ntsiab lus silica ntawm cov iav tiaj tus yog kwv yees li 70-75 feem pua, thiab cov ntsiab lus silica ntawm iav fiber ntau yog qis dua 60 feem pua.
