Chingwe cha FRP ndi njira yofunika kwambiri komanso yofunika kwambiri yoyendetsera bwino kwambiri pomanga mphamvu yovomerezeka yotsutsa-purossion. Pakati pawo, FRP yokhala ndi manja imagwiritsidwa ntchito kwambiri chifukwa cha ntchito yake yosavuta, kuvuta komanso kusinthasintha. Titha kunena kuti njira yam'manja yopitilira 80% ya frp odana ndi kuwononga. gawo. "Zida zitatu zazikuluzikulu" zipika, firiti ndi pufuti ufa mu frp ndi mafupa a frp, kuchirikiza mphamvu ya mankhwala a Frp, ndipo ndi gawo lofunikira kwambiri.

Malinga ndi kusiyana kwa malo okhala ndi sing'anga, zinthu zaluso za fry zimasinthanso. Kusankha kwazinthu zofunikira panthawi yomanga ndi chinthu chofunikira kuti awonetsetse kuti chotsiriza cha fry chimatha kuzolowera zachilengedwe ndi kukhazikika kwake. Chifukwa chake, kusankha kwa zida za FRP kuyenera kutsimikizika musanamangidwe. Mwachitsanzo, zida zolimbikitsira zida zomwe zaimira ndi ulusi wagalasi ndi zida zofala kwambiri za miliri, zomwe zimakana kuvunda kwa asidi ambiri; Komabe, sakanagwirizana ndi hydrofluoric acid ndi otentha phosphoric acid. Gwiritsani ntchito polyester, polypropylene ndi nsalu zina zopangidwa ndi chilengedwe ndipo mumathanso kusankha kugwiritsa ntchito nsalu kapena gaute, ndipo zinthu zina za FEP zimafunikira zida zachilengedwe. M'mawu, kusankha kwa dzanja lakumanja ndi luso komanso chidziwitso point kuti ukadaulo ndi opanga ayenera kudziwa.

Pazinthu zopangira frp, ulusi waukulu wolimbitsa ndi ulusi wagalasi, kaya ndi nsalu, kumverera kapena ulusi. Cholinga chachikulu ndikuti kuwonjezera pa chinthu chamtengo wapatali, chilinso ndi zinthu zabwino kwambiri:
01 kukana kwa mankhwala
Mafuta a fiberglass atorglass osakhazikika sadzawola, nkhungu kapena kuwonongeka. Amalimbana ndi acid ambiri kupatula Hydrofluoric ndi otentha phosphoric acid.
02 mokhazikika
Zithunzi zagalasi zamagalasi zomwe zimagwiritsidwa ntchito kupanga zovala zagalasi sizitambasuka kapena kutsuka chifukwa cha kusintha kwa mlengalenga. Akuluakulu a nomwenal nthawi yopuma ndi 3-4%. Mzere wamba wamafuta wokulirapo wa kuchuluka kwa e -galasi ndi 5.4 × 10-6 cm / cm / ° / °
03 magwiridwe antchito
Zovala za fiberglass zimakhala ndi zokwanira za kuwonjezeka kwa mafuta komanso mawonekedwe apamwamba. Fiberglass imatha kutentha kwambiri kuposa asbestos kapena ulusi wanyama.
04 Mphamvu yayikulu
Fiberglass Yarn ili ndi kuchuluka kwamphamvu kwambiri. Mapaundi a fiberglass ulusi wolimba kwambiri ngati waya wachitsulo. Kutha kwa mphamvu yopanga kapena kugwirizanitsa mu nsalu kumawonjezera mwayi wogwiritsa ntchito zomaliza.
Kulimbana ndi kutentha kwa 05
Mafuta azomwe amagalasi sawotcha ndipo amakhala osaphika kwambiri ndikuchiritsa kutentha nthawi zambiri kumakumana ndi mafakitale. Fiberglass imasungapo pafupifupi 50% ya mphamvu yake pa 700 ° F ndi 25% pa 1000 ° F.
06 wotsika hygrophicity
Nyimbo za fiberglass zimapangidwa ndi ulusi wopanda phokoso motero ali ndi mayamwidwe ochepa kwambiri.
07 Chabwino
Mphamvu yolimba ya Idelelec komanso yotsika kwambiri, pamodzi ndi madzi otsamwa madzi otsika komanso kutentha kwa kutentha kwambiri, pangani nsalu za fiberglass zabwino kwambiri pakusunga kwamagetsi.
Kusinthasintha kwazinthu 08
Zithunzi zabwino kwambiri zomwe zimagwiritsidwa ntchito mu ulusi wa fiberglass, mitundu yosiyanasiyana ya ulusi ndi zosintha, mitundu yosiyanasiyana yamiyala, ndipo kumaliza ntchito zambiri kupanga fiberglass yothandiza mafakitale.
09 mtengo wotsika mtengo
Zovala za fiberglass zimatha kugwira ntchitoyo ndipo zikufanana ndi mtengo kuti zipangire nsalu zopangidwa ndi zachilengedwe.

Chifukwa chake, fiber galasi ndi dzanja labwino limakhala ndi mphamvu yolimbikitsa, yomwe ndi yachuma, yotsika mtengo, komanso yosavuta kuyigwiritsa ntchito. Ndi imodzi mwazinthu zogwiritsidwa ntchito kwambiri pakati pa zinthu zambiri zothandiza kwambiri.
