Fiberglass classification, raw khoom formulation txiav txim siab kev ua tau zoo, thiab cab specifications cuam tshuam rau daim ntaub ntawv.

Fiberglassyog ib qho ntawm feem ntau siv reinforcing fibers nyob rau hauv daim ntawv ntawm cov ntaub ntawv sib xyaw. Nws qhov kev faib tawm tuaj yeem ua raws li peb qhov tseem ceeb: cov khoom siv raw, cov yam ntxwv ntawm kev ua haujlwm, thiab tus cab specifications. Cov pawg sib txawv sib txawv rau cov lus qhia sib txawv. Hauv qab no yog cov ncauj lus kom ntxaws kev faib tawm thiab daim ntawv thov kev hloov kho logic.

I. Kev faib tawm los ntawm Raw Material Composition
Cov ntaub ntawv raw rau fiberglass feem ntau yog quartz xuab zeb, dej qab zib tshauv, thiab limestone. Los ntawm kev kho cov mis, iav tshuab nrog cov tshuaj sib txawv tuaj yeem tsim. Cov qeb uas muaj raws li nram no:

1. Alkali -dawbfiberglass(E-fiberglass): Cov ntsiab lus ntawm alkali hlau oxide yog<2%, and the main components are SiO2, Al2O3, CaO, and B2O3. It contains no obvious alkali metal components. It has excellent insulation properties, balanced mechanical strength, good corrosion resistance (except for strong acids and alkalis), and high cost-effectiveness. It is mainly used as the core reinforcement in general-purpose composite materials, such as wind turbine blades, electronic and electrical insulation boards, automotive body parts, pipelines, and storage tanks.

2. Nruab nrab-alkali fiberglass (C-fiberglass) muaj alkali hlau oxide cov ntsiab lus ntawm 8% ~ 12% thiab cov ntsiab lus B2O3 tsawg, ua rau tus nqi qis dua alkali-dawb fiberglass. Nws cov tshuaj tiv thaiv corrosion (tshwj xeeb yog acid tsis kam) zoo dua rau alkali -dawb fiberglass, tab sis nws cov rwb thaiv tsev thiab lub zog txhua yam qis dua me ntsis. Nws yog qhov tsim nyog rau daim ntawv thov kev tiv thaiv corrosion uas tsis tshua muaj kev rwb thaiv tsev, xws li tshuaj lom neeg corrosion{11}}cov yeeb nkab tiv thaiv, asphalt waterproofing cov khoom siv ntxiv, thiab cov khoom siv fiberglass zoo tib yam.

3. High-alkali fiberglass has an alkali metal oxide content >12%, feem ntau yog ua los ntawm cov iav siv dua tshiab, ua rau tus nqi qis heev. Nws cov khoom siv kho tshuab thiab huab cua tsis zoo, thiab nws cov rwb thaiv tsev tsis muaj zog. Nws yog tsuas yog siv nyob rau hauv uas tsis yog - cov cuab yeej cuab tam, xws li qis- cov khoom kawg xws li thermal rwb thaiv tsev paj rwb, suab rwb thaiv tsev xav, thiab cov ntaub ntawv lim.

4. High-lub zog fiberglass (S-fiberglass/HS-} fiberglass) muaj cov ntsiab lus tsis tshua muaj alkali hlau. Nws lub zog tensile thiab elastic modulus yog ntau dua E-fiberglass, thiab nws muaj qhov zoo siab - kub tsis kam. Nws yog tsuas yog siv rau hauv siab -cov ntaub ntawv ua tau zoo, xws li cov khoom siv hauv tsev kawm ntawv theem nrab, cov khoom siv ua kis las siab (- golf clubs, sailboat masts), thiab cov khoom siv tiv thaiv tub rog.

5. High-modulus fiberglass (M-fiberglass) muaj MgO thiab lwm yam khoom, nrog rau elastic modulus ntawm 95-110 GPa. Nws muaj zog tiv thaiv deformation, tab sis nws lub zog yog me ntsis qis dua li ntawm S-fiberglass. Nws yog tsuas yog siv nyob rau hauv zus tau tej cov structural Cheebtsam uas yuav tsum tau siab rigidity, xws li satellite brackets, precision ntsuas vaj tse, thiab high-end automotive tsav shafts.

6. Alkali-resistant fiberglass (AR-fiberglass) suav nrog alkali-cov khoom tiv thaiv xws li ZrO2, nrog cov ntsiab lus ntawm cov hlau alkali tswj tau. Nws tuav cov khoom ruaj khov hauv alkaline ib puag ncig xws li cov cement thiab gypsum, thiab muaj kev tiv thaiv zoo rau alkali corrosion. Nws yog tsuas yog siv nyob rau hauv zus tau tej cov fiber ntau-cov cement (GRC) cov khoom, pob zeb tawg-resistant reinforcement, thiab phab ntsa rwb thaiv tsev mesh hauv kev tsim kho.

II. Kev faib tawm los ntawm Kev Ua Yeeb Yam Kev Ua Haujlwm Qhov kev faib tawm no ntxiv cov khoom siv raw, tsom mus rau "kev ua haujlwm zoo" ntawm fiberglass.

1. Kub-resistantfiberglass has a softening point >900℃, thiab qee hom tuaj yeem tiv taus luv luv -lub sijhawm kub siab tshaj 1000℃. Nws muaj cov thermal stability zoo thiab feem ntau yog siv hauv aero- cav cua sov shields, industrial kiln rwb thaiv tsev txheej, thiab hluav taws kub- cov ntaub ntawv retardant composite.

2. Insulating fiberglass muaj lub ntim resistivity> 10¹⁴ Ω·cm, tsawg dielectric poob, thiab zoo arc kuj. Nws yog tsuas yog siv rau hauv kev tsim cov ntawv luam tawm Circuit Board (PCB) substrates, siab -voltage hluav taws xob rwb thaiv tsev bushings, radar radomes, thiab lwm yam.

3. Corrosion-Resistant fiberglass tiv taus cov kua qaub, alkalis, thiab cov kuab tshuaj organic, nthuav tawm qhov kev ua haujlwm tsawg kawg nkaus hauv cov cheeb tsam tshuaj lom neeg hnyav. Nws yog tsuas yog siv nyob rau hauv chemical cia tso tsheb hlau luam, marine corrosion-cov khoom tiv thaiv, thiab cov khoom siv kho dej khib nyiab.

III. Kev faib tawm los ntawm Tow Size Tow loj yog hais txog tus naj npawb ntawm cov monofilaments hauv ib lub hnab fiber ntau, cuam tshuam ncaj qha rau molding efficiency thiab cov khoom ua tau zoo ntawm cov khoom sib xyaw.

1. Cov xov paj zoo (cov hlua me): Cov xov tooj ntawm monofilaments ib pob yog <2000, nrog tus nqi qis tex. Nws muaj zoo wettability thiab siab molding precision, thiab yuav woven rau hauv zoo fabrics. Nws yog tsuas yog siv nyob rau hauv zus tau tej cov high - precision aerospace Cheebtsam, hluav taws xob- qib tooj liab- clad laminates, high- khoom ntaus pob ncaws pob, thiab precision ntsuas qhov chaw.

2. Cov xov paj nruab nrab: Tus naj npawb ntawm monofilaments ib pob yog 2000 ~ 4800. Nws sib npaug molding efficiency thiab cov khoom sib xws, muab tus nqi siab -effectiveness. 3. ** Ribbon (Large Tow):** Feem ntau yog siv rau hauv kev tsim cov khoom nruab nrab-cov khoom loj xws li cua turbine hniav tawv nqaij, automotive lub cev, thiab nkoj decks.

4. ** Roving (Large Tow):** Nrog ntau tshaj 4800 filaments ib nras thiab ib tug high tex tus nqi, roving muaj ntau lawm efficiency thiab nqi tsev nqi tsawg, ua rau nws haum rau loj ntau lawm txheej txheem. Nws yog tsuas yog siv nyob rau hauv zus tau tej cov yam ntxwv loj xws li pultruded profiles (xws li, FRP kav, profile txhawb), tshuaj tsuag- cov khoom molded (xws li, cia tso tsheb hlau luam, nkoj hulls), thiab cov khoom qhov txhab (xws li, siab- siab gas cylinders).

5. ** Chopted Ribbon:** Nruam fiberglass yog txiav rau hauv luv fibers ntawm 3-50 mm. Nws tuaj yeem muab faib ua cov xov paj (rau cov ntaub ntawv sib xyaw) thiab hauv av fiber ntau (rau fillers). Nws yog yooj yim dispersed thiab yuav tov nrog resins, yas, thiab lwm yam matrices rau molding. Nws yog tsuas yog siv nyob rau hauv zus tau tej covfiberglassCov yas yas (FRP) txhaj tshuaj molded qhov chaw, BMC / DMC molding compounds, thiab lub tsev mortar reinforcement. Hauv cov ntsiab lus, fiberglass tuaj yeem ua kom pom tseeb raws li peb qhov loj me: cov khoom siv raw, cov yam ntxwv ntawm kev ua haujlwm, thiab cov lus qhia tshwj xeeb. Qhov kev faib tawm meej no tsis tsuas yog pab cov tuam txhab qis qis kom haum cov ntaub ntawv tsim nyog rau cov xwm txheej sib txawv xws li cua zog, aviation, kev tsim kho, thiab hluav taws xob, tab sis kuj muab cov kev taw qhia rau cov tuam txhab saum toj kawg nkaus hauv cov qauv kev ua kom zoo, kev hloov kho, thiab lwm yam kev tshawb fawb thiab kev loj hlob. Raws li daim ntawv thov cov cheeb tsam txuas ntxiv mus, kev faib tawm ntawm fiberglasss yuav ua kom zoo dua yav tom ntej, ntxiv kev txhawb nqa kev lag luam kev hloov mus rau ntau haiv neeg thiab kev xav tau ntawm ntau yam kev lag luam thiab pab cov khoom siv sib xyaw ua lag luam ua tiav qhov kev sib npaug ntawm kev ua tau zoo thiab tus nqi.
