Muaj MSG - Fiberglass
"Fiberglass" feem ntau yog hais txog fiberglass, siab -kev ua tau zoo inorganic tsis yog-cov khoom siv hlau ua los ntawm cov khoom siv raw xws li quartz xuab zeb thiab limestone los ntawm siab - kub melting thiab kos duab. Nws cov txiaj ntsig tseem ceeb nyob hauv kev ua tiav lub zog ze rau cov hlau nrog qhov hnyav hnyav heev (3.3 grams tuaj yeem rub tau 100 mais), thaum tseem muaj cov khoom tsis yog -combustible, corrosion-resistant, thiab insulating zog. Nws qhov tsis zoo yog brittleness thiab tsis zoo hnav tsis kam.
I. Classification ntawmFiberglass
Fiberglass tsis yog ib yam khoom, tab sis ib tsev neeg loj. Raws li cov tshuaj muaj pes tsawg leeg thiab cov khoom, nws tau muab faib ua cov pawg hauv qab no:
1. Kev faib tawm los ntawm Alkali Metal Content (Qhov kev faib tawm yooj yim tshaj plaws)
Nov yog tus qauv tseem ceeb rau kev paub qhov txawv "zoo" ntawm fiberglass:
Alkali-dawb fiberglass (E- iav)Sodium oxide 0% ~ 2%. Feem ntau siv, nrog zoo heev hluav taws xob rwb thaiv tsev, feem ntau hu ua "hluav taws xob iav." Nws yog lub substrate rau Circuit Court boards hauv cov khoom siv hluav taws xob.
Nruab nrab-alkali fiberglass (C- iav): Sodium oxide 8% ~ 12%. Cov tshuaj tiv thaiv corrosion zoo dua li alkali-dawb fiberglass, tab sis me ntsis qis zog thiab tsis zoo hluav taws xob rwb thaiv tsev.
1. **High-alkali fiberglass (A- iav):** Muaj ntau dua 13% sodium oxide. Nws muaj dej tsis zoo heev thiab tsis tshua muaj siv nyob rau hauv cov khoom siv niaj hnub no.
2. ** Kev faib tawm los ntawm Kev Ua Haujlwm thiab Daim Ntawv Thov (Tshwj xeeb fiberglasss) **
S- iav (High-lub zog fiberglass): Tus huab tais ntawm lub zog. Nws lub zog tensile yog li 25% siab dua E-qib, feem ntau yog siv nyob rau hauv siab -kawg teb xws li tub rog, aerospace, thiab mos mos tsho khuam.
AR- iav (Alkali-resistant fiberglass): Tshwj xeeb yog tsim los rau cov cement / pob zeb. Nws tuaj yeem tiv taus qhov yaig ntawm siab -alkali tshuaj hauv cov cement thiab yog cov khoom siv tseem ceeb hauv GRC cov khoom.
E-CR iav: Boron-dawb thiab alkali-dawb, muaj zog heev tiv taus acid thiab alkali corrosion, tshwj xeeb yog tsim rau cov kav dej hauv av thiab cov chaw cia khoom.
D- iav (Low-dielectric iav): Zoo dielectric zog, siv nyob rau hauv siab -frequency kev sib txuas lus ib puag ncig.
3. ** Kev faib tawm raws li daim ntawv **
Nruam fiber ntau (ntev fiber ntau): Infinitely ntev filaments, siv los weave electronic fabrics thiab ua rovings.
Short fibers (taw -ntev fiber ntau): Cov fibers tsis tu ncua, siv rau hauv cov khoom siv thermal rwb thaiv tsev.
Iav wool: Ib qho fibrous, cov khoom tseem ceeb rau thermal rwb thaiv tsev thiab soundproofing.
II. Kev siv yooj yim
fiberglass plays lub luag haujlwm tseem ceeb ua "skeleton ntawm cov khoom sib xyaw." Nws yog tsis tshua muaj siv nyob rau hauv ib leeg, tab sis feem ntau yog ua ke nrog substrates xws li cob, xis mas, thiab gypsum muab cov yam ntxwv ntawm "soft sab nrauv thiab rigid sab hauv."
1. Kev Lag Luam Hluav Taws Xob thiab Cov Ntaub Ntawv Kev Lag Luam: Qhov "Tsis Pom Cov Pob Txha" zais hauv cov xov tooj ntawm tes
Cov core circuit boards (tooj liab-clad laminates) ntawm koj lub xov tooj smartphones thiab ntsiav tshuaj yog ua los ntawm ultra-cov ntaub ntawv fiberglass zoo impregnated nrog resin.
Txiav- Ntug Case: Cov cuab yeej siv tam sim no tso cai rau kos duab 100-kilometer-ntev filaments los ntawm 3.3 grams iav, nrog ib txoj kab uas hla ntawm tsuas yog 4.1 micrometers (zoo dua li 1/30th thickness ntawm tib neeg cov plaub hau), ua rau cov ntaub nyias nyias li cicada lub tis.
2. Kev Thauj Mus Los: Ib Tug Hero rau Kev Nyuaj Siab
Automotive thiab High -Speed Rail: Siv los tsim cov khoom siv sab hauv lub cev, lub pob tw, thiab cov hoods. Piv nrog rau cov pa roj carbon fiber ntau, fiberglass muaj tus nqi tseem ceeb, ua rau nws tus nqi ntau tshaj - siv lub teeb yuag.
Shipbuilding: Hulls rau cov nkoj nuv ntses thiab yachts, muab kev tiv thaiv corrosion thiab kev tiv thaiv, zoo heev txo nqi txij nkawm.
Aerospace: Secondary load- bearing cov yam ntxwv xws li alarm interiors thiab radomes.
3. Lub zog tshiab thiab kev tiv thaiv ib puag ncig: Ib tug ncej ntawm kev hloov pauv ntsuab
Cua zog: Cov khoom siv tseem ceeb rau cov cua turbine hniav. Ib tug hniav mus txog 100 meters ntev yog txhawb tag nrho los ntawm ib tug fiberglass woven skeleton.
Environmental Facilities: Chemical storage tanks, pickling tanks, chimneys, and pipeworks. Siv lub zog corrosion kuj ntawm E-CR fiberglass, nws hloov cov hlau.
4. Cov vaj tse thiab kev tsim vaj tsev: Ib qho kev hloov rau cov hlau nplaum uas muaj zog
GRC Cheebtsam: Siv AR fiberglass reinforced cement los tsim cov ntaub thaiv phab ntsa, hniav moldings, thiab sculptures; nyias-walled thiab lub teeb yuag.
Kev Tiv Thaiv Corrosion: Hauv cov txuas hniav ntawm ntug dej hiav txwv thiab cov chaw kho dej phwj tuaj, fiberglass reinforced pob zeb (GFRP) tsis xeb lossis nthuav dav zoo li cov hlau, ua rau lub neej ntev ntev.
5. Cov Khoom Siv Txhua Hnub: Los ntawm cov dab da dej mus rau lub kaus mom hlau
Chav Dej Fixtures: Cov chav da dej sib xyaw ua ke, cov dab da dej, thiab cov kav dej septic yog yuav luag tag nrho ua los ntawm fiberglass.
Kev Tiv Thaiv: Cov kaus mom hlau thiab cov ntaub thaiv kev kub ntxhov siv cov kev tiv thaiv siab ntawm fiberglass kom nqus tau lub zog.
