Kev loj hlob ntawm fiberglass
Fiberglassmuaj keeb kwm ntev ntawm kev loj hlob. Nyob rau xyoo 1930, tom qab cov neeg Asmeskas tau tsim cov txheej txheem ntawm kev siv platinum crucibles mus txuas ntxiv kos iav fibers thiab tshuab iav ntaub plaub nrog chav, kev tsim cov iav fibers tsim kev lag luam niaj hnub. Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis niaj hnub no, cov kev xav tau siab dua tau muab tso rau ntawm cov khoom siv kho tshuab thiab kub-tiv taus ntawm iav fibers, uas tau coj mus rau qhov tshwm sim ntawm ntau qhov tshwj xeeb iav fibers txij li xyoo 1960, xws li kub-resistant iav fibers. , high-strength iav fibers, thiab high-modulus iav fibers. Tus nqi ntawmfiberglassthiab lwm yam. Cov txheej txheem kev tsim kho qhov muag pom tau zoo tshaj plaws ntawm cov iav fiber ntau yog cov iav fiber ntau "ZenTron" tshaj tawm los ntawm Dow Corning thawj zaug ntawm 41st SAMPE International Conference nyob rau lub Peb Hlis 1996. Nws yog ua los ntawm high-silica. cov ntsiab lus iav raws li raw khoom. Ua los ntawm fibers siv cov cuab yeej hu ua Single-busting lossis Single-end 30 hom. Cov khoom no yuav tsum muaj tsawg dua cov kauj ruam tom qab ua tiav, tuaj yeem tiv thaiv fiber ntau puas, thiab txo cov nqi.
Peb lub teb chaws muaj keeb kwm ntawm kev kawm iav fiber ntau xyoo lawm. Thaum ntxov li 1958, kuv lub teb chaws tsimfiberglasstej nkoj nquam siv tes lay-up cov txheej txheem, thiab tsimfiberglassphaj thiab foob pob ua ntxaij launchers siv lamination thiab dov cov txheej txheem. Xyoo 1960, cov tsev tshawb fawb tshawb fawb tau tsim nyob rau hauv Beijing, Shanghai, thiab Harbin. Xyoo 1961, ablation-resistant iav fiber kawg tau tsim tiav. Xyoo 1970, 44m loj iav radome tau tsim los siv tes muab tshuaj txhuam cov qauv vaj huam sib luag. Xyoo 1975, FRP Society tau tsim. Xyoo 1983, Tuam Tshoj Cov Khoom Siv Hauv Tsev Tshawb Fawb tau ua tiav kev sim ua kom muaj alkali-resistant iav fiber ntau. Reinforced sulfate aluminate low-alkali cement composite cov ntaub ntawv. Xyoo 1988, Wuhan University of Technology tau ua tiav kev tshawb fawb ua haujlwm siab iav fiber ntau ntxiv magnesium oxychloride cov ntaub ntawv sib xyaw. Tam sim no, ob qho tib si cov ntaub ntawv sib xyaw tau mus txog kev tsim khoom lag luam thiab tau siv dav hauv kev tsim kho. Phab ntsa, qhov rooj tua hluav taws, lub tank dej, qhov cua ducts, chav dej qab nthab, tsev cog khoom thav duab kos duab, thiab lwm yam.
