Fiberglass muaj ntau yam zoo xws li lub zog siab thiab lub teeb, tiv taus corrosion, tiv taus kub siab, thiab ua haujlwm hluav taws xob zoo. Nws yog ib qho ntawm cov ntaub ntawv sib xyaw ua ke uas siv ntau. Tib lub sijhawm, Tuam Tshoj kuj yog lub ntiaj teb tus tsim khoom fiberglass loj tshaj plaws.
1. Fiberglass yog dab tsi?
Fiberglass yog ib yam khoom siv inorganic uas tsis yog hlau uas muaj kev ua tau zoo heev. Nws yog ib yam khoom siv ntuj tsim uas muaj silica ua cov khoom siv tseem ceeb, thiab ntxiv cov khoom siv hlau oxide tshwj xeeb. Tom qab sib tov kom sib npaug, nws yaj ntawm qhov kub siab, thiab cov iav molten ntws los ntawm lub qhov xau. , nyob rau hauv qhov kev ua ntawm lub zog rub ceev ceev, nws raug rub thiab txias sai thiab khov ua cov fibers zoo heev.
Lub txoj kab uas hla ntawm fiberglass monofilament yog txij li ob peb microns mus rau nees nkaum microns, uas yog sib npaug rau 1 / 20-1 / 5 ntawm ib txoj plaub hau. Txhua pob ntawm cov xov fiber yog tsim los ntawm ntau pua lossis txawm tias ntau txhiab tus monofilaments.
Cov yam ntxwv tseem ceeb ntawm fiberglass:
Qhov tsos yog ib daim duab cylindrical nrog ib qho chaw du, qhov seem hla yog ib lub voj voog tiav, thiab qhov seem hla voj voog muaj lub peev xwm thauj khoom muaj zog; qhov tsis kam ntawm cov roj thiab kua hla dhau yog me me, tab sis qhov chaw du ua rau lub zog sib txuas ntawm cov fiber me me, uas tsis zoo rau kev sib xyaw nrog cov resin; qhov ceev feem ntau yog 2.50-2.70 g / cm3, feem ntau nyob ntawm cov iav sib xyaw; lub zog tensile siab dua li lwm cov fibers ntuj thiab cov fibers hluavtaws; cov khoom siv brittle, nws qhov elongation thaum tawg yog me heev; dej tsis kam thiab acid tsis kam zoo dua, thaum alkali tsis kam yog qhov tsawg. Qhov sib txawv.
2. Kev faib tawm ntawmcov fiberiav
Los ntawm qhov kev faib tawm ntev, nws muaj peev xwm muab faib ua cov iav fiber txuas ntxiv, fiberglass luv luv (fiberglass ntev ruaj khov) thiab fiberglass ntev (LFT).
3. Daim ntawv thov ntawm fiberglass
Fiberglass muaj lub zog tensile siab, modulus siab ntawm elasticity, tsis-flammability, tshuaj lom neeg tsis kam, dej tsawg nqus, thiab kev ua haujlwm zoo. , dav siv hauv ntau qhov chaw.
Cov fiberglass txawv teb chaws feem ntau muab faib ua plaub pawg raws li kev siv khoom: cov khoom siv txhawb nqa rau cov yas thermosetting, cov khoom siv fiberglass txhawb nqa rau cov thermoplastics, cov khoom siv cement gypsum txhawb nqa, cov khoom siv fiberglass textile, uas cov khoom siv txhawb nqa suav txog 70-75%, cov khoom siv fiberglass textile Cov khoom siv suav txog 25-30%. Los ntawm qhov kev xav tau ntawm cov khoom siv hauv qab, cov khoom siv hauv paus suav txog li 38% (suav nrog cov kav dej, dej hiav txwv desalination, tsev sov thiab dej tsis nkag, kev txuag dej, thiab lwm yam), kev thauj mus los suav txog li 27-28% (yachts, tsheb, tsheb ciav hlau ceev ceev, thiab lwm yam), thiab cov khoom siv hluav taws xob suav txog li 17%.
Hauv kev xaus lus, cov teb thov ntawm fiberglass feem ntau suav nrog kev thauj mus los, cov ntaub ntawv tsim kho, kev lag luam hluav taws xob, kev lag luam tshuab, kev lag luam petrochemical, kev lom zem thiab kev siv tshuab tiv thaiv teb chaws.
