Fiberglass: Katundu, Njira, Misika

Kapangidwe ndi makhalidwe a fiberglass
Zigawo zazikulu ndi silika, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, ndi zina zotero. Malinga ndi kuchuluka kwa alkali mu galasi, ikhoza kugawidwa m'magulu awa:
①,fiberglass yopanda alkali(sodium oxide 0% ~ 2%, ndi galasi la aluminiyamu borosilicate)
2, fiberglass yapakati ya alkali (sodium oxide 8% ~ 12%, ndi galasi la boron kapena boron lopanda soda-laimu silicate) ndifiberglass yokhala ndi alkali yambiri(sodium oxide 13% kapena kuposerapo, ndi galasi la soda-lime silicate).
Makhalidwe: fiberglass kuposa ulusi wachilengedwe, kutentha kwambiri, kosayaka, kukana dzimbiri, kutchinjiriza kutentha, kutchinjiriza mawu, mphamvu yayikulu yokoka, kutchinjiriza bwino magetsi. Koma ndi yofooka, yosalimba komanso yosalimba. Yogwiritsidwa ntchito popanga mapulasitiki olimba kapena rabala yolimbikitsidwa, ngati chinthu cholimbikitsira, fiberglass ili ndi makhalidwe awa:
①, mphamvu yayikulu yokoka, kutalika pang'ono (3%).
②, Kuchuluka kwa kusinthasintha, kulimba bwino.
③, Imatambasuka kwambiri mkati mwa malire a elasticity komanso mphamvu yayikulu yokoka, kotero imayamwa mphamvu yayikulu yokhudza kugwedezeka.
④, Ulusi wosapangidwa ndi zinthu zachilengedwe, wosayaka, wokana mankhwala bwino.
⑤, Kuyamwa kwa madzi ndi kochepa.
⑥, Kukhazikika kwa sikelo ndi kukana kutentha ndikwabwino.
⑦, Yosavuta kugwiritsa ntchito, imatha kupangidwa kukhala ulusi, mitolo, nsalu, ndi mitundu ina yosiyanasiyana ya zinthu.
⑧, Yowonekera bwino komanso yopepuka yotumizira.
⑨, Kumamatira bwino ku utomoni.
⑩, Yotsika mtengo.
⑪, sikophweka kuwotcha, imatha kusungunuka kukhala mikanda yooneka ngati galasi pa kutentha kwakukulu.

Njira yopangirafiberglass
Pali njira ziwiri zopangira fiberglass:
Kuumba kawiri: njira yojambulira yophimbidwa
Kuumba kamodzi kokha: Njira yojambulira uvuni wa dziwe
Njira yojambulira waya wowomba m'madzi, galasi loyamba lopangidwa ndi zinthu zopangira zinthu zophikidwa limasungunuka kutentha kwambiri kukhala mpira wagalasi, kenako mpira wagalasi umasungunukanso, ndipo mpira wagalasi umapangidwa ndi silika wosaphika wagalasi. Njirayi imagwiritsa ntchito mphamvu zambiri, njira yosakhazikika yopangira zinthu, ntchito yochepa komanso zovuta zina, zomwe zimachotsedwa ndi opanga magalasi akuluakulu.
Njira yojambulira waya wa dziwe la chlorite ndi zinthu zina zopangira mu uvuni zimasungunuka kukhala yankho lagalasi, kupatula thovu la mpweya kudzera munjira yopititsidwa ku mbale yotulutsira madzi yokhala ndi porous leak, zojambula mwachangu zopangidwa ndi fiberglass filaments. Uvuniwo ukhoza kulumikizidwa kudzera m'njira zingapo kupita ku mbale mazanamazana zotulutsira madzi kuti upangidwe nthawi imodzi. Njirayi ndi yosavuta, yosunga mphamvu, yokhazikika, yogwira ntchito bwino komanso yokolola zambiri, kuti ithandize kupanga zinthu zambiri zokha, kukhala chinthu chachikulu pakupanga zinthu padziko lonse lapansi, ndipo njira yopangira fiberglass inali yoposa 90% ya kupanga zinthu padziko lonse lapansi.

Msika wa Fiberglass
Malinga ndi zipangizo zosiyanasiyana zomwe zasankhidwa kuti zipangidwe, fiberglass ikhoza kugawidwa m'magulu osakhala a alkali, apakatikati a alkali,fiberglass yapadera yokhala ndi alkali yambiri; Malinga ndi mawonekedwe osiyanasiyana a ulusi, fiberglass ikhoza kugawidwa m'ma fiberglass osalekeza, fiberglass yotalika mokhazikika, ubweya wagalasi; Malinga ndi kusiyana kwa mainchesi a monofilaments, fiberglass ikhoza kugawidwa m'ma ulusi wopyapyala kwambiri (m'mimba mwake osakwana 4 μm), ulusi wachikulire (m'mimba mwake wa 3 ~ 10 μm), ulusi wapakati (m'mimba mwake wa) woposa 20μm), ulusi wopyapyala (m'mimba mwake wa pafupifupi 30μm). Malinga ndi magwiridwe antchito osiyanasiyana a ulusi, fiberglass ikhoza kugawidwa m'ma fiberglass wamba, fiberglass yolimba yolimbana ndi asidi ndi alkali, fiberglass yolimba yolimbana ndi asidi,fiberglass yosagwira kutentha kwambiri, fiberglass yamphamvu kwambiri ndi zina zotero.
