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. Owens Illinois kambani yaive hombe yegirazi kugadzira mabhodhoro 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 yakarohwa 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 vakaona kuti chinhu chechidiki ichi chine zvakawanda zvakanakira - huremu huremu, simba rakakwirira, kuvhara 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 se kaolin, pyrophyllite, jecha requartz uye limestone kuburikidza nemaitiro akati wandei akadai sekunyungudika kwepamusoro-tembiricha, kudhirowa kwewaya uye kupeta zvinoenderana neimwe fomula. Yayo monofilament dhayamita iri pakati akati wandei mamicrons uye anopfuura 20 microns, iyo yakaenzana 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.
