Cov khoom tseem ceeb sib txawv ntawm fiberglass daim ntaub thiab iav
Mar 31, 2022
Fiberglass gingham yog ib qho untwisted roving tiaj weave, uas yog ib qho tseem ceeb hauv paus khoom rau tes-nteg iav fiber reinforced plastics. Lub zog ntawm gingham npuag yog feem ntau nyob rau hauv warp thiab weft kev taw qhia ntawm cov ntaub. Rau lub sijhawm uas xav tau siab warp lossis weft lub zog, nws tseem tuaj yeem ua rau hauv cov ntaub unidirectional, uas tuaj yeem npaj ntau dua untwisted rovings hauv warp lossis weft kev taw qhia. Warp ntaub, ib leeg weft ntaub.
Cov ntaub fiberglass yog kos cov iav rau hauv cov iav zoo heev, thiab cov iav filaments nyob rau lub sijhawm no muaj qhov yooj yim. Lub fiberglass yog spun rau hauv xov paj, thiab ces woven rau hauv fiberglass ntaub los ntawm ib tug loom. Vim hais tias cov iav filament yog nyias nyias thiab thaj chaw ntawm ib chav tsev loj, qhov kub tsis kam ua haujlwm tau txo. Nws zoo li melting ib tug nyias tooj liab hlau nrog ib tug tswm ciab. Tab sis iav tsis hlawv. Kev kub hnyiab peb tuaj yeem pom yog qhov tseeb ntawm cov khoom siv cob coated ntawm cov iav fiber ntau daim ntaub, los yog cov impurities txuas, txhawm rau txhim kho kev ua haujlwm ntawm daim ntaub fiberglass. Tom qab cov ntaub fiberglass ntshiab los yog qee cov txheej txheem kub resistant, nws tuaj yeem siv los ua cov khoom xws li cov khaub ncaws refractory, hnab looj tes refractory, thiab cov pam vov refractory. Txawm li cas los xij, yog tias nws nyob rau hauv kev sib cuag nrog daim tawv nqaij, cov fibers tawg yuav ua rau tawv nqaij thiab nws yuav khaus heev.
Fiberglass daim ntaub feem ntau yog siv rau hauv tes nteg txheej txheem, thiab cov fiberglass reinforced khoom square daim ntaub yog tsuas yog siv nyob rau hauv lub nkoj hulls, cia tso tsheb hlau luam, txias yees, ships, tsheb, tso tsheb hlau luam, thiab lub tsev cov ntaub ntawv. Fiberglass daim ntaub yog tsuas yog siv nyob rau hauv kev lag luam rau: tshav kub rwb thaiv tsev, hluav taws kub tiv thaiv thiab nplaim retardant. Cov khoom siv nqus cua kub ntau thaum nws hlawv los ntawm cov nplaim taws thiab tuaj yeem tiv thaiv cov nplaim taws los ntawm kev sib cais ntawm huab cua.
1. Raws li cov khoom xyaw: feem ntau nruab nrab alkali, tsis-alkali, siab alkali (kom cais cov muaj pes tsawg leeg ntawm alkali hlau oxides hauv iav fiber), tau kawg, kuj tseem muaj kev faib tawm los ntawm lwm cov khoom, tab sis muaj ntau ntau yam, tsis yog ib qho. los ntawm ib. suav sau.
2. Raws li cov txheej txheem tsim khoom: crucible hlau kos duab thiab pas dej kiln hlau kos duab.
3. Raws li ntau yam: muaj cov xov paj ntaub, cov xov paj ncaj, cov xov paj dav hlau, thiab lwm yam.
Tsis tas li ntawd, nws yog qhov txawv ntawm ib txoj kab uas hla fiber ntau, TEX tooj, twist, thiab hom sizing tus neeg sawv cev. Kev faib cov iav fiber ntau yog tib yam li kev faib tawm ntawm cov xov paj fiber ntau. Ntxiv nrog rau cov saum toj no, nws kuj muaj xws li: weaving method, gram hnyav, dav, thiab lwm yam.
Cov khoom siv tseem ceeb sib txawv ntawm cov iav fiber ntau thiab iav: Cov khoom siv tseem ceeb sib txawv ntawm cov iav fiber ntau thiab iav tsis loj, feem ntau yog vim 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.
