Cov iav fiber ntau muaj ntau yam zoo xws li lub zog siab thiab lub teeb yuag, kev tiv thaiv corrosion, kub tsis kam, zoo hluav taws xob rwb thaiv tsev kev ua tau zoo, thiab lwm yam. Nws yog ib qho ntawm cov khoom siv raw rau cov khoom sib xyaw.Nyob rau tib lub sijhawm, Tuam Tshoj kuj yog lub ntiaj teb loj tshaj plaws tsim cov iav fiber ntau.
1. Dab tsi yog fiber ntauiav?
Cov iav fiber ntau yog cov khoom siv tsis muaj hlau tsis muaj hlau nrog kev ua haujlwm zoo, yog cov ntxhia hauv ntuj nrog silica ua cov khoom siv tseem ceeb, ntxiv cov hlau oxide ntxhia raw cov ntaub ntawv, sib xyaw ua ke, molten ntawm qhov kub thiab txias, molten iav kua ntws los ntawm cov dej ntws tawm, Lub luag hauj lwm ntawm high-speed rub gravitational quab yuam yog kos thiab ceev ceev txias thiab kho rau hauv ib qho zoo heev tsis tu ncua fiber ntau.
Cov iav fiber ntau monofilament txoj kab uas hla ntawm ob peb microns mus rau ntau tshaj nees nkaum microns, sib npaug rau cov plaub hau ntawm 1/20-1/5, txhua pob ntawm fibers yog tsim los ntawm ntau pua lossis ntau txhiab tus monofilaments.
Cov khoom siv iav fiber ntau: Cov tsos ntawm lub ntsej muag cylindrical du, ntu ntu yog lub voj voog ua tiav, puag ncig hla ntu kom tiv taus lub peev xwm thauj khoom;roj thiab kua los ntawm qhov tsis kam yog me me, tab sis qhov saum npoo yog du kom lub zog tuav ntawm fiber ntau me me, tsis haum rau kev sib xyaw nrog cov cob;Qhov ceev yog feem ntau nyob rau hauv 2.50-2.70 g / cm3, nyob ntawm seb lub iav muaj pes tsawg leeg;tensile zog dua lwm yam ntuj fibers, hluavtaws fibers kom siab;Cov ntaub ntawv nkig, qhov elongation ntawm kev tawg yog me me Cov dej tsis kam thiab acid kuj zoo, thaum cov alkali kuj tsis zoo.
2.Kev faib tawm iav fiber ntau
Nws tuaj yeem muab faib ua cov iav fiber ntau, luv iav fiber ntau (taw ntev iav fiber ntau) thiab iav fiber ntau (LFT) los ntawm kev faib tawm ntev.
Los ntawm cov ntsiab lus hlau alkali tuaj yeem muab faib ua alkali-dawb, qis, nruab nrab thiab siab, feem ntau hloov nrog alkali-dawb, uas yog, E iav fiber ntau, kev hloov kho hauv tsev feem ntau yog siv E iav fiber ntau.
3.Cov iav fiber ntau tuaj yeem siv rau dab tsi
Cov iav fiber ntau muaj lub zog tensile siab, siab elasticity, tsis-combustibility, tshuaj tiv thaiv, tsis tshua muaj dej nqus, kev ua haujlwm zoo thiab lwm yam zoo heev, feem ntau yog cov khoom sib xyaw hauv cov khoom siv ntxiv, cov khoom siv hluav taws xob rwb thaiv tsev thiab cov ntaub ntawv rwb thaiv tsev, Circuit Court substrate, thiab lwm yam. ., dav siv nyob rau hauv ntau yam teb.
Cov iav fiber ntau txawv teb chaws tau muab faib ua plaub pawg raws li cov khoom siv: cov khoom siv ntxiv rau cov thermosetting plastics, iav fiber reinforcing cov ntaub ntawv rau thermoplastics, cement gypsum reinforcing cov ntaub ntawv, thiab iav fiber ntau textile cov ntaub ntawv, ntawm cov ntaub ntawv txhawb zog rau 70-75% thiab iav. fiber ntau cov ntaub ntawv suav nrog 25-30%.Los ntawm qhov kev xav tau qis qis, kev tsim kho vaj tsev muaj kwv yees li 38% (nrog rau cov kav xa dej, kev tshem tawm, kev ua kom sov hauv tsev thiab kev tiv thaiv dej, kev txuag dej, thiab lwm yam), kev thauj mus los yog kwv yees li 27-28% (yacht, tsheb, high-speed rail, thiab lwm yam). thiab cov khoom siv hluav taws xob muaj txog li 17%.
Los xaus, daim ntawv thov thaj chaw ntawm iav fiber ntau yog roughly tsheb thauj mus los, siv cov ntaub ntawv, hluav taws xob kev lag luam, mechanical kev lag luam, petrochemical kev lag luam, leisure thiab kab lis kev cai, thiab lub teb chaws tiv thaiv technology.
