Fiberglass ili ndi zabwino zambiri monga kulimba kwambiri komanso kulemera pang'ono, kukana dzimbiri, kukana kutentha kwambiri, komanso kuyendetsa bwino kwamagetsi.Ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito pophatikiza.Pa nthawi yomweyo, China ndiyenso padziko lonse lapansi opanga magalasi a fiberglass.
1. Kodi fiberglass ndi chiyani?
Fiberglass ndi zinthu zopanda zitsulo zopanda zitsulo zomwe zimagwira ntchito bwino kwambiri.Ndi mchere wachilengedwe wokhala ndi silika monga chopangira chachikulu, ndikuwonjezera zinthu zina zachitsulo za oxide mineral.Pambuyo kusakaniza mofanana, imasungunuka kutentha kwakukulu, ndipo galasi losungunuka limayenda kudzera mumphuno yotayira., pansi pa mphamvu yokoka yothamanga kwambiri, imakokedwa ndi kuzizira mofulumira ndikukhazikika kukhala ulusi wabwino kwambiri wopitirira.
Kutalika kwa fiberglass monofilament kumayambira ma microns ochepa mpaka ma microns makumi awiri, omwe ndi ofanana ndi 1/20-1/5 ya tsitsi.Mtolo uliwonse wa ulusi wa ulusi umapangidwa ndi mazana kapena masauzande a monofilaments.
Zofunikira za fiberglass:
Maonekedwe ndi mawonekedwe a cylindrical okhala ndi malo osalala, gawo la mtanda ndi bwalo lathunthu, ndipo gawo lozungulira lozungulira liri ndi mphamvu yonyamula katundu;mpweya ndi madzi akudutsa kukana ndi kochepa, koma pamwamba yosalala imapangitsa kuti fiber cohesion mphamvu ikhale yaying'ono, yomwe siikugwirizana ndi kuphatikiza ndi utomoni;kachulukidwe nthawi zambiri amakhala 2.50-2.70 g/cm3, makamaka zimatengera kapangidwe ka galasi;kulimba kwamphamvu ndikwapamwamba kuposa ulusi wina wachilengedwe ndi ulusi wopangira;brittle material, elongation yake yopuma ndi yaying'ono kwambiri;kukana madzi ndi kukana asidi ndi bwino, pamene kukana kwa alkali kumakhala kochepa.Kusiyana.
2. Gulu lafibergalasi
Kuchokera pamagawo aatali, amatha kugawidwa kukhala magalasi opitilira magalasi, magalasi amfupi a fiberglass (magalasi osasunthika) ndi magalasi atali (LFT).
3. Kugwiritsa ntchito fiberglass
Magalasi a Fiberglass ali ndi mphamvu zolimba kwambiri, modulus wapamwamba wa elasticity, osayaka, kukana mankhwala, kuyamwa kwamadzi otsika, komanso kukonza bwino., amagwiritsidwa ntchito kwambiri m'madera osiyanasiyana.
Fiberglass yakunja imagawidwa m'magulu anayi molingana ndi kugwiritsa ntchito mankhwala: zida zolimbikitsira mapulasitiki okhazikika a thermosetting, zida zolimbikitsira za fiberglass za thermoplastics, zopangira simenti ya gypsum, zida za nsalu za fiberglass, zomwe zida zolimbikitsira zimakhala 70-75%, zida zopangira nsalu za fiberglass. kuwerengera 25-30%.Pakuwona kufunika kwa kutsika kwa mtsinje, zomangamanga zimakhala pafupifupi 38% (kuphatikiza mapaipi, kuchotsa mchere m'madzi a m'nyanja, kutentha kwa nyumba ndi kutsekereza madzi, kusunga madzi, ndi zina zotero), zoyendera zimakhala pafupifupi 27-28% (ma yacht, magalimoto, njanji yothamanga kwambiri, etc.), ndipo zamagetsi zimakhala pafupifupi 17%.
Mwachidule, magawo ogwiritsira ntchito magalasi a fiberglass nthawi zambiri amaphatikiza mayendedwe, zida zomangira, mafakitale amagetsi, mafakitale amakina, mafakitale a petrochemical, chikhalidwe chopumula ndiukadaulo wachitetezo cha dziko.
