Nkhungu ndiye chida chachikulu chopangira zinthu za FRP. Nkhungu zimatha kugawidwa m'magawo achitsulo, aluminiyamu, simenti, rabala, parafini, FRP ndi mitundu ina malinga ndi zinthuzo. Nkhungu za FRP zakhala nkhungu zomwe zimagwiritsidwa ntchito kwambiri popanga FRP chifukwa cha kuphweka kwawo kupanga, kupezeka mosavuta kwa zipangizo zopangira, mtengo wotsika, nthawi yochepa yopangira komanso kukonza kosavuta.
Zofunikira pamwamba pa nkhungu za FRP ndi nkhungu zina zapulasitiki ndizofanana, ndipo nthawi zambiri pamwamba pa nkhungu pamakhala pamlingo umodzi kuposa pamwamba pa chinthucho. Pamene nkhungu ili bwino, nthawi yopangira zinthu imakhala yochepa komanso nthawi yokonza zinthuyo imakhala yabwino, ndipo nthawi yogwiritsira ntchito nkhungu imakhala yayitali. Nkhungu ikaperekedwa kuti igwiritsidwe ntchito, kuti nkhungu ikhale yabwino, kukonza nkhungu kuyenera kuchitika bwino. Kukonza nkhungu kumaphatikizapo: kuyeretsa pamwamba pa nkhungu, kuyeretsa nkhungu, kukonza zowonongeka, ndi kupukuta nkhungu. Kukonza nkhungu nthawi yake komanso moyenera ndiye poyambira pokonza nkhungu. Kuphatikiza apo, njira yoyenera yosamalira nkhungu ndiyo chinsinsi. Tebulo lotsatirali likuwonetsa njira zosiyanasiyana zosamalira ndi zotsatira zofananira zosamalira.
Njira zosiyanasiyana zosamalira nkhungu zosiyanasiyana ndi izi:
①Zinthu zatsopano kapena zinthu zomwe sizinagwiritsidwe ntchito kwa nthawi yayitali
Choyamba, yeretsani ndikuyang'ana pamwamba pa nkhungu, ndi kukonza zofunikira pa zigawo zowonongeka komanso zosafunikira za nkhungu. Kenako, gwiritsani ntchito chosungunulira kuti muyeretse pamwamba pa nkhungu, kenako gwiritsani ntchito makina opukuta ndi phala lopukuta kuti mupukute pamwamba pa nkhungu kamodzi kapena kawiri mutatha kuumitsa. Malizitsani kupukuta ndi kupukuta katatu motsatizana, kenako pukutani sera kachiwiri, ndikupukutanso musanagwiritse ntchito.
②Chinthu chomwe chikugwiritsidwa ntchito
Choyamba, onetsetsani kuti nkhungu yapakidwa sera ndi kupukutidwa katatu konse, ndipo ziwalo zomwe zimawonongeka mosavuta komanso zovuta kuzichotsa ziyenera kupakidwa sera ndi kupukutidwa musanagwiritse ntchito nthawi iliyonse. Kachiwiri, kuti pakhale chinthu chachilendo (chingakhale polyphenylene kapena sera) chomwe chimawoneka mosavuta pamwamba pa nkhungu chomwe chakhala chikugwiritsidwa ntchito kwa nthawi yayitali, chiyenera kutsukidwa nthawi yake. Pukutani pang'onopang'ono), ndipo gawo lotsukidwa limachotsedwa malinga ndi nkhungu yatsopano.
③Mu nkhungu yosweka
Pa nkhungu zomwe sizingakonzedwe pa nthawi yake, mungagwiritse ntchito mabuloko a sera ndi zinthu zina zomwe zimawonongeka mosavuta ndipo sizingakhudze kuuma kwa gel coat kuti zidzaze ndikuteteza mbali zowonongeka za nkhungu, ndikupitiliza kugwiritsa ntchito. Kwa zomwe zingathe kukonzedwa pa nthawi yake, gawo lowonongeka liyenera kukonzedwa kaye, ndipo gawo lokonzedwa liyenera kukonzedwa ndi anthu osachepera 4 (pa 25 °C). Gawo lokonzedwa liyenera kupukutidwa, kupukutidwa ndikuchotsedwa lisanayambe kugwiritsidwa ntchito.
Kusamalira bwino pamwamba pa nkhungu kumatsimikizira nthawi yogwira ntchito ya nkhungu, kukhazikika kwa ubwino wa pamwamba pa chinthucho, komanso kukhazikika kwa kupanga, kotero payenera kukhala chizolowezi chabwino chosamalira nkhungu.
