Khawv koob li koj - fiberglass!

Thaum xyoo 1920, thaum muaj kev nyuaj siab loj hauv Tebchaws Meskas, tsoomfwv tau tshaj tawm txoj cai zoo: txwv tsis pub. Qhov kev txwv tsis pub dhau 14 xyoo, thiab cov neeg tsim khoom lag luam cawv tau teeb meem ib qho tom qab. Owens Illinois lub tuam txhab yog lub tuam txhab iav iav loj tshaj plaws hauv Tebchaws Meskas thaum lub sijhawm ntawd. Nws tsuas tuaj yeem saib iav furnaces tua. Lub sijhawm no, ib tug txiv neej uas muaj hwj chim, ua si tua neeg, tau tshwm sim dhau los ntawm lub khob rauv thiab pom tias qee lub khob kua dej tau tawg rau hauv cov duab fiber ntau. Kev ua si zoo li Newton raug ntaus lub taub hau los ntawm lub kua, thiabiav fibertau nyob rau theem ntawm keeb kwm txij thaum ntawd los.
Ib xyoos tom qab, Tsov Rog Ntiaj Teb Zaum Ob tau tshwm sim, thiab cov khoom siv tsis tshua muaj. Txhawm rau ua kom tau raws li qhov xav tau ntawm kev npaj ua tub rog, iav fiber tau los ua ib qho kev hloov.
Tib neeg maj mam pom tias cov khoom siv hluas no muaj ntau yam zoo - lub teeb yuag, siab zog, zoo rwb thaiv tsev, tiv thaiv tshav kub thiab rwb thaiv tsev kub. Yog li ntawd, tso tsheb hlau luam, dav hlau, riam phom, tsho tiv thaiv mos txwv thiab lwm yam siv iav fiber ntau.
iav fiber ntauyog ib qho tshiab inorganiccov khoom siv tsis yog xim hlau, uas yog tsim los ntawm tej yam ntuj tso minerals xws li kaolin, pyrophyllite, quartz xuab zeb thiab limestone los ntawm ob peb txheej txheem xws li kub-kub melting, hlau kos duab thiab winding raws li ib tug tej yam mis nyuj. Nws txoj kab uas hla monofilament yog nyob nruab nrab ntawm ob peb microns thiab ntau tshaj 20 microns, uas yog sib npaug rau 1 / 20-1 / 5 ntawm cov plaub hau filament. Txhua pob ntawm fiber ntau precursor yog tsim los ntawm ntau pua lossis ntau txhiab tus monofilaments.

Tuam Tshoj txoj kev lag luam iav fiber ntau tau nce xyoo 1958. Tom qab 60 xyoo ntawm txoj kev loj hlob, ua ntej kev hloov kho thiab qhib, nws tsuas yog ua haujlwm rau kev tiv thaiv hauv tebchaws thiab kev lag luam tub rog, thiab tom qab ntawd tig mus rau kev siv pej xeem, thiab ua tiav kev loj hlob sai.
