Fiber iav muaj ntau yam zoo xws li lub zog tensile siab, lub teeb yuag, corrosion kuj, kub tsis kam, thiab zoo hluav taws xob rwb thaiv tsev kev ua tau zoo, uas ua rau 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) Fiberglass yog dab tsi?
Cov iav fiber ntau yog cov khoom siv tsis zoo uas tsis yog xim hlau nrog kev ua haujlwm zoo.Nws yog cov ntxhia ntuj tsim los ntawm silica, nrog tshwj xeeb hlau oxide ntxhia raw cov ntaub ntawv ntxiv.Tom qab sib tov sib xyaw, nws melts ntawm qhov kub thiab txias, thiab cov kua iav molten ntws tawm los ntawm cov dej ntws tawm.Nyob rau hauv lub high-ceev tensile quab yuam, nws yog stretched thiab ceev ceev txias thiab solidified rau hauv tsis tshua muaj zoo nruam fibers.
Qhov txoj kab uas hla ntawm iav fiber ntau monofilament muaj li ntawm ob peb microns mus rau ntau tshaj nees nkaum microns, sib npaug rau 1/20-1/5 ntawm cov plaub hau, thiab txhua pob ntawm fibers yog tsim los ntawm ntau pua lossis ntau txhiab tus monofilaments.
Cov yam ntxwv ntawm cov iav fiber ntau: Cov tsos yog cov duab cylindrical du nrog lub voj voog ua tiav, thiab lub voj voog hla ntu muaj zog muaj peev xwm thauj khoom;Gas thiab kua muaj qhov tsis zoo rau kev nkag mus, tab sis qhov chaw du txo qhov cohesion ntawm fibers, uas tsis tsim nyog rau kev sib txuas nrog cov resin;Qhov ceev yog feem ntau ntawm 2.50 thiab 2.70 g / cm3, feem ntau nyob ntawm cov iav muaj pes tsawg leeg;Lub zog tensile yog siab dua lwm yam ntuj fibers thiab hluavtaws fibers;Cov ntaub ntawv brittle muaj qhov elongation tsawg heev thaum so;Dej zoo thiab acid tsis kam, tab sis tsis zoo alkali tsis kam.
2) Kev faib cov iav fiber ntau
Los ntawm kev faib tawm ntev, nws tuaj yeem muab faib ua cov iav fiber ntau, luv iav fiber ntau (taw ntev iav fiber), thiab iav fiber ntau (LFT).
Nruam iav fiber ntau yog tam sim no siv iav fiber ntau hauv Suav teb, uas feem ntau hu ua "ntev fiber ntau".Cov neeg sawv cev manufacturers yog Jushi, Mount Taishan, Xingwang, thiab lwm yam.
Tsau ntev iav fiber ntau feem ntau hu ua "short fiber", uas feem ntau yog siv los ntawm txawv teb chaws-nyiaj hloov kho cov nroj tsuag thiab qee cov lag luam hauv tsev.Cov neeg sawv cev ntawm cov tuam txhab lag luam yog PPG, OCF thiab CPIC hauv tsev, thiab cov neeg tsawg ntawm Jushi Mount Taishan.
LFT tau tshwm sim hauv Suav teb xyoo tas los no, nrog cov neeg sawv cev ntawm cov tuam txhab suav nrog PPG, CPIC, thiab Jushi.Tam sim no, cov lag luam hauv tsev xws li Jinfa, Shanghai Nayan, Suzhou Hechang, Jieshijie, Zhongguang Nuclear Juner, Nanjing Julong, Shanghai Pulit, Hefei Huitong, Changsha Zhengming, thiab Rizhisheng tag nrho muaj ntau lawm.
Raws li cov ntsiab lus ntawm alkali hlau, nws tuaj yeem muab faib ua alkali dawb, qis nruab nrab siab, thiab feem ntau hloov kho thiab ntxiv dag zog nrog alkali dawb, piv txwv li E-iav fiber.Hauv Suav teb, E-iav fiber ntau yog siv los hloov kho.
3) Kev thov
Raws li cov khoom siv, nws tau muab faib ua plaub pawg: cov khoom siv ntxiv rau cov yas thermosetting, iav fiber reinforced cov ntaub ntawv rau thermoplastics, cement gypsum reinforced cov ntaub ntawv, thiab iav fiber ntau cov ntaub ntawv.Ntawm lawv, cov ntaub ntawv txhawb nqa suav txog 70-75%, thiab cov ntaub ntawv iav fiber ntau suav txog 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 cua sov thiab dej tsis zoo, kev txuag dej, thiab lwm yam), kev thauj mus los txog li 27-28% (yachts, tsheb, high-speed rail, thiab lwm yam), thiab cov khoom siv hluav taws xob muaj txog li 17%.
