Mashiripiti sewe - fiberglass!

Mukupera kwema1920, panguva yekuora mwoyo kukuru muUnited States, hurumende yakabudisa Mutemo unoshamisa: kurambidza.Rambidzo yacho yakagara kwemakore 14, uye vagadziri vemabhodhoro ewaini vakanga vari mudambudziko rimwe pashure pomumwe.Kambani yeOwens Illinois ndiyo yaive yakakura kugadzira mabhodhoro egirazi muUnited States panguva iyoyo.Yaingokwanisa kuona magirazi emoto akadzimwa.Panguva iyi, mumwe murume anoremekedzwa, muurayi wemitambo, akapfuura nepachoto chegirazi ndokuona kuti rimwe girazi remvura rakadururwa rakafuridzirwa kuita fiber chimiro.Mitambo inoita senge Newton akarohwa mumusoro neapuro, uyegirazi fiberyave iri pachikuva chenhoroondo kubva ipapo.
Kwapera gore, Hondo Yenyika Yechipiri yakatanga, uye zvinhu zvakajairika zvaive zvishoma.Kuti zvizadzise zvinodiwa zvekugadzirira kurwa kwemauto, fiber yegirazi yakave inotsiva.
Vanhu zvishoma nezvishoma vakawana kuti chinhu chechidiki ichi chine zvakawanda zvakanakira - kureruka kurema, kusimba kwepamusoro, kuvharisa kwakanaka, kuchengetedza kupisa uye kupisa kupisa.Naizvozvo, matangi, ndege, zvombo, bulletproof vests uye zvichingodaro zvese zvinoshandisa girazi fiber.
Girazi fiberis a new inorganicisiri-simbi zvinhu, iyo inogadzirwa kubva kumaminerari echisikigo akadai sekaolin, pyrophyllite, jecha requartz uye limestone kuburikidza nemaitiro akati wandei akadai sekunyunguduka kwepamusoro-tembiricha, kudhirowa kwewaya uye kumonereka zvinoenderana neimwe fomula.Yayo monofilament dhayamita iri pakati akati wandei ma microns uye anopfuura 20 microns, ayo akaenzana ne1 / 20-1 / 5 yebvudzi filament.Imwe neimwe bundle ye fiber precursor inoumbwa nemazana kana kunyange zviuru zve monofilaments.

China girazi faibha indasitiri yakasimuka muna 1958. Mushure memakore 60 ebudiriro, pamberi pekuvandudza uye kuvhura, yainyanya kushumira kudzivirira kwenyika uye indasitiri yemauto, ndokuzotendeukira kukushandiswa kwehurumende, uye yakawana kukurumidza kusimudzira.
