Glass fiber cloth is made from glass pellets or waste glass through high-temperature melting, drawing, winding, and weaving. Lub cheeb ntawm ib leeg filovent li ntawm ob peb microns kom dhau 20 microns, sib npaug rau 1 / 20-1 / 5 lub cheeb ntawm tib neeg cov plaub hau. Txhua txoj kev sib tw ntawm fiber ntau yog muaj ntau pua lossis txawm tias ntau txhiab tus neeg filaments.
Cov yam ntxwv zoo li cas ntawm iav Fiber ntau?
1. Nws tuaj yeem siv rau hauv qhov kub ntawm -} 196 qib mus rau 300 degree, resistant.
2. Nws yog tsis - cov nplaum thiab tsis yooj yim ua rau txhua yam.
3. Nws yog qhov ntsuas tshuaj tiv thaiv, suav nrog cov muaj zog acids, alkalis, aqua regia, thiab ntau yam kuab tshuaj muaj zog.
4. Nws muaj qhov qis coefficient ntawm kev sib txhuam, ua rau nws xaiv zoo rau roj - dawb- lubrication.
5. Nws muaj qhov pauv hluav taws xob ntawm 6-13%.
6. Nws muaj rwb thaiv tsev siab, UV kev tiv thaiv, thiab anti- cov khoom zoo li qub.
7. Nws yog qhov muaj zog thiab muaj cov kws kho zoo tshaj plaws . 8. cov tshuaj lom neeg Kuj
Txoj kev ua haujlwm ntawm daim ntaub fiberglass
Qee tus neeg nug qhov ua haujlwm ntawm daim ntaub fiberglass yog. Nws zoo li xav txog lub tsev tsim ntawm cov cement thiab cov hlau nplaum hlau. Fiberglass daim ntaub ua zoo li cov hlau tuav hlau, txhawb cov fiberglass txhawb cov yas.
Dab tsi thov cov ntaub fiberglass siv rau?
Daim ntaub fiberglass feem ntau yog siv hauv txhais tes nteg - cov txheej txheem. Fiberglass -} Cov ntaub qhwv Woven feem ntau, cov tsheb thauj khoom, tsheb thauj khoom, tso tsheb hlau luam, thiab vaj tse qauv. Hauv kev lag luam, cov ntaub fiberglass feem ntau yog siv rau cov rwb thaiv tsev thermal, kev tiv thaiv hluav taws, thiab nplaim hluavtaws. Thaum nthuav tawm cov nplaim taws, cov khoom no muaj cua kub tseem ceeb, tiv thaiv cov nplaim taws los ntawm kev hla dhau thiab insulating huab cua.
Fiberglass Hniav Ntaub Ntawv
1. Los ntawm composition:Mas nruab nrab -} alkali {{1} {{{{{{{alkali oxide cov ntsiab lus ntawm cov iav fiber). Tseem muaj lwm cov kev sib tw raws li kev sib xyaw, tab sis cov ntau ntau ntau dhau los sau ntawm no.
2. Los ntawm kev tsim khoom tsim:Kev kos duab txaj muag thiab tank kiln.
3. Los ntawm ntau yam:Ply yarn, xov paj, tshuaj lom, thiab lwm yam. Ntxiv rau cov lej sib txuas ua ke Qhov kev faib tawm ntawm daim ntaub fiberglass zoo ib yam li ntawm cov xov paj fiber ntau. Ntxiv rau cov saum toj no, nws tseem suav nrog weave, qhov hnyav, thiab dav.
Dab tsi yog qhov sib txawv ntawm daim ntaub fiberglass thiab iav?
Cov khoom tseem ceeb ntawm cov ntaub fiberglass thiab iav tsis tseem ceeb. Qhov sib txawv tseem ceeb yog cov khoom sib txawv uas yuav tsum muaj thaum lub sijhawm tsim khoom, uas ua rau qee qhov sib txawv ntawm cov qauv. Tiaj lub iav muaj kwv yees li 70-75% silica, thaum lub sij hawm fiberglass feem ntau muaj tsawg dua 60%.
Iav yog cov khoom siv inorganic melted ntawm qhov kub (saum 800 degree; tsev neeg lub iav feem ntau tau yaj ntawm 1100 degree). Hauv qab nws cov khoom muag muag, nws tsis muaj kev hloov tshuaj. Saum toj no taw tes, nws tsuas yog softens, melts, lossis decomposes, tab sis tsis hlawv.
Daim ntaub fiberglass yog tsim los ntawm daim duab khob rau hauv cov kev nplua uas tsis tshua zoo, uas yog li hloov tau yooj yim heev. Cov filaments yog spun rau hauv xov paj thiab tom qab ntawd woven nyob rau hauv lub ntom los tsim cov ntaub fiberglass. Vim tias cov iav fibers tau zoo heev thiab muaj thaj chaw loj hauv ib chav tsev loj, lawv cov kev tiv thaiv kub yog txo. Ib yam li tswm ciab tuaj yeem yaj ib lub taub hlau tooj liab nyias nyias, nws muaj peev xwm pom cov nplaim taws.
Txawm li cas los xij, iav tsis hlawv. Cov nplaim pom yog qhov tshwm sim los ntawm cov txheej txheem resin lossis impurities adhering rau daim ntaub fiberglass, uas txhim kho nws cov kev ua tau zoo. Cov ntaub dawb fiberglass, lossis cov ntaub coated nrog siab {2} {}}}}}}} {}} Cov hnab looj tes tiv thaiv, hnab looj tes, thiab pam vov. Txawm li cas los xij, yog tias nws tau nkag mus rau hauv kev sib chwv nrog daim tawv nqaij, cov nplais tawg tuaj yeem ua rau khaus khaus thiab khaus.
Dab tsi yog qhov sib txawv ntawm daim ntaub fiberglass thiab fiberglass txhawb cov yas (frp)?
Daim ntaub fiberglass yog cov khoom siv los ua Frp cov khoom. Frp yog qhov tseem ceeb ib qho composite yas ua los ntawm kev sib txuas khob fibers nrog cov resins, tshuaj tua neeg, thiab lwm yam khoom siv los ntawm ntau yam txheej txheem, tom qab ntawd kho tau.
Kuv yuav ua li cas yog tias kuv ua yuam kev mus ua cov ntaub fiberglass ntawm kuv cov khaub ncaws lossis lub cev?
Feem ntau, txoj kab uas hla ntawm cov pa roj fiberglass filaments yog nruab nrab ntawm 9 thiab 13 microns. Floating hais hauv fiberglass hauv qab 6 microns tuaj yeem nkag mus rau lub ntsws thiab ua rau muaj kev ua pa, yog li yuav xyuam xim. Fiberglass hauv qab 6 microns yog feem ntau imported. Hnav daim npog ntsej muag yog yuav tsum tau ua thaum lub sijhawm ua haujlwm. Cov neeg sib tiv tauj nquag tuaj yeem ua rau muaj pa rau hauv lub ntsws, ua rau pneumoconiosis.
Yog tias cov tawv nqaij fiberglass tau txais ntawm koj lub cev, cov tawv nqaij rhiab yuav tau pom tias tsis haum thiab khaus, tab sis qhov no feem ntau tsis yog teeb meem loj. Cov uas muaj tawv nqaij rhiab yuav txhim kho cov hlwv me me, uas yog qhov tsis haum tshuaj thiab tuaj yeem kho nrog- kev siv tshuaj noj.
