Fiberglass ili ndi zabwino zambiri monga nyonga zambiri komanso kulemera kwakukulu, kutukwana kwa kutentha, kutentha kwa magetsi. Ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kawirikawiri. Nthawi yomweyo, China ndinso wopanga kwambiri padziko lonse lapansi wa fiberglass.
1. Kodi fiberglass ndi chiyani?
Fiberglass ndi mankhwala osavomerezeka omwe ali ndi zitsulo. Ndi mchere wachilengedwe wokhala ndi silica monga momwe zinthu zazikuluziriri zimawonjezera michere yazitsulo zopangira. Pambuyo posakanikiranso, imasungunuka kutentha kwambiri, ndipo galasi losungunula limayenda kudutsa phokoso. , mothandizidwa ndi mphamvu yokoka kwambiri, imakokedwa ndipo imakhazikika mwachangu ndikukhazikika mu ulusi wopitilira.
M'mawa a fiberglass monofulaments kuchokera ku microns microns mpaka microns microns, omwe ndi ofanana ndi 1 / 20-1 / 5 a tsitsi. Mtolo uliwonse wazingwe zamitundu imapangidwa ndi mazana kapena masauzande azono.
Zoyambira za fiberglass:
Maonekedwe ndi mawonekedwe a cylindrical okhala ndi mawonekedwe osalala, gawo la mtanda ndi bwalo lathunthu, ndipo gawo lozungulira la mtanda limakhala ndi katundu wamphamvu. Mafuta ndi madzi odutsa amadzimadzi ndi ochepa, koma nkhope yosalala imapangitsa kuti coulion colite alowe ing'ono, yomwe siyothandiza kuphatikiza ndi utomoni; Kuchulukitsa nthawi zambiri mu 2.50-2.70 g / cm3, makamaka zimatengera kuchuluka kwagalasi; Mphamvu ya anthu ndiyokwera kuposa ulusi wina wachilengedwe ndi ulusi wopangidwa; Zinthu zakuthanthwe, kutalika kwake nthawi yopuma ndi kochepa kwambiri; Kukaniza kwa madzi ndi acid kukana ndikwabwino, pomwe alkali kukana kuli kochepa. Kusiyana.
2. Gulu laulusigalasi
Kuyambira kutalika kwa kalasi, imatha kugawidwa m'mapiri opitilira galasi, ma fiberglass (okhazikika) ndi fiberglass (LFT).
3. Kugwiritsa ntchito fiberglass
Firberglass imakhala ndi mphamvu yayikulu, solus exustos, osakhala ndi chipongwe, kukana kwa mankhwala, madzi otsika madzi, ndikupanga magwiridwe antchito abwino. , amagwiritsidwa ntchito kwambiri m'minda yosiyanasiyana.
Chizindikiro chachilendo chimagawidwa m'magulu anayi malinga ndi kugwiritsa ntchito mankhwala: Zinthu zolimbitsa thupi zolimbitsa thupi, zida zolimbitsa thupi za 70-75%, za fiberglass zopangidwa ndi zida za 25-30%. Kuchokera pakuwona kotsika, maakaunti opanga maakaunti pafupifupi 38% (kuphatikiza mapaipi a panyanja, nyumba yotentha, ndi zina zopitilira 2%.
Kuwerenga, magawo a fiberglass nthawi zambiri kumaphatikizapo mayendedwe, zomangira, makampani amagetsi, makampani amakina, chikhalidwe chamakampani oteteza zachilengedwe komanso chikhalidwe chopumira dziko.
