Fiberglass muaj ntau yam zoo xws li siab zog thiab lub teeb yuag, corrosion kuj, kub tsis kam, thiab zoo hluav taws xob rwb thaiv tsev kev ua tau zoo.Nws yog ib qho ntawm cov khoom siv feem ntau siv.Nyob rau tib lub sijhawm, Tuam Tshoj kuj yog lub ntiaj teb tus tsim khoom loj tshaj plaws ntawm fiberglass.
1. Dab tsi yog fiberglass?
Fiberglass yog cov khoom siv tsis muaj hlau tsis muaj hlau nrog kev ua haujlwm zoo.Nws yog cov ntxhia hauv ntuj nrog silica ua cov khoom siv tseem ceeb, ntxiv cov hlau oxide ntxhia raw cov ntaub ntawv.Tom qab sib tov sib npaug, nws yog melted ntawm qhov kub thiab txias, thiab cov iav molten ntws los ntawm cov pa xau nozzle., nyob rau hauv qhov kev txiav txim ntawm high-ceev rub quab yuam, nws yog kos thiab sai txias thiab solidified rau hauv tsis tshua muaj zoo nruam fibers.
Txoj kab uas hla ntawm fiberglass monofilament txawv ntawm ob peb microns mus rau nees nkaum microns, uas yog sib npaug rau 1/20-1/5 ntawm cov plaub hau.Txhua pob ntawm fiber ntau yog tsim los ntawm ntau pua lossis ntau txhiab tus monofilaments.
Cov yam ntxwv tseem ceeb ntawm fiberglass:
Cov tsos yog ib tug cylindrical zoo nrog ib tug du nto, tus ntoo khaub lig seem yog ib tug ua tiav lub voj voog, thiab lub voj voog hla ntu muaj zog load bearing peev xwm;cov roj thiab cov kua dhau los kuj yog me me, tab sis qhov chaw du ua rau cov fiber ntau cohesion quab yuam me me, uas tsis haum rau kev sib xyaw nrog cov cob;Qhov ceev yog feem ntau nyob rau hauv 2.50-2.70 g / cm3, feem ntau nyob ntawm iav muaj pes tsawg leeg;tensile lub zog yog siab dua lwm yam ntuj fibers thiab hluavtaws fibers;brittle cov ntaub ntawv, nws elongation ntawm so yog heev me me;dej tsis kam thiab acid tsis kam yog zoo dua, thaum alkali kuj tsis tshua muaj.Qhov txawv.
2. Kev faib tawm ntawmfiber ntauiav
Los ntawm kev faib tawm ntev, nws tuaj yeem muab faib ua cov iav fiber ntau txuas ntxiv, luv fiberglass (taw ntev fiberglass) thiab ntev fiberglass (LFT).
3. Daim ntawv thov ntawm fiberglass
Fiberglass muaj lub zog tensile siab, siab modulus ntawm elasticity, tsis-flammable, tshuaj tsis haum, tsis tshua muaj dej nqus, thiab kev ua haujlwm zoo., dav siv nyob rau hauv ntau yam teb.
Cov fiberglass txawv teb chaws tau muab faib ua plaub pawg raws li cov khoom siv: cov khoom siv ntxiv rau cov khoom siv thermosetting, fiberglass reinforcing cov ntaub ntawv rau cov thermoplastics, cement gypsum reinforcing cov ntaub ntawv, fiberglass textile cov ntaub ntawv, ntawm cov ntaub ntawv reinforcing account rau 70-75%, fiberglass textile cov ntaub ntawv. tus account rau 25-30%.Los ntawm qhov kev xav ntawm qhov kev xav tau qis qis, kev tsim kho vaj tsev muaj kwv yees li 38% (suav nrog cov kav xa dej, dej hiav txwv desalination, tsev sov thiab dej tsis zoo, kev txuag dej, thiab lwm yam), kev thauj mus los txog li 27-28% (yachts, tsheb, tsheb ciav hlau, tsheb ciav hlau, thiab lwm yam), thiab lwm yam), thiab cov khoom siv hluav taws xob muaj txog li 17%.
Raws li kev suav sau, daim ntawv thov kev lag luam ntawm fiberglass feem ntau suav nrog kev thauj mus los, cov khoom siv hauv tsev, kev lag luam hluav taws xob, kev lag luam tshuab, kev lag luam petrochemical, kev lom zem kab lis kev cai thiab kev tiv thaiv lub teb chaws.
