Mpando wagalasiNdi chinthu chonga pepala chopangidwa ndi zingwe zopitilira kapena zingwe zodulidwa zomwe sizimayang'aniridwa ndi zomangira za mankhwala kapena zochita zamakina.

Zofunikira pakugwiritsa ntchito:

Kukonza manja:Kuyika manja mmwamba ndiyo njira yayikulu yopangira FRP m'dziko langa.Matingi odulidwa ndi ulusi wagalasi, Matumba osalekeza ndi matemba osokedwa onse angagwiritsidwe ntchito poika manja. Kugwiritsa ntchito matemba osokedwa kungachepetse kuchuluka kwa zigawo ndikuwonjezera magwiridwe antchito oika manja. Komabe, chifukwa matemba osokedwa ali ndi ulusi wambiri woika ulusi wa mankhwala, ma thovuwo si osavuta kuwachotsa, zinthu za FRP zimakhala ndi thovu zambiri zooneka ngati singano, ndipo pamwamba pake pamakhala poyipa komanso sipamakhala posalala. Kuphatikiza apo, nsalu yosokedwa ndi yolemera, ndipo chophimba cha nkhungu ndi chachifupi kuposa cha matemba odulidwa ndi matemba osalekeza. Popanga zinthu zokhala ndi mawonekedwe ovuta, zimakhala zosavuta kupanga mabowo pamalo opindika. Njira yoika manja imafuna kuti matembawo akhale ndi mawonekedwe a kulowerera mwachangu kwa resin, kuchotsa mosavuta thovu la mpweya, komanso kuphimba bwino nkhungu.

Kusokonekera kwa mpweya:Njira yopukutira ndi imodzi mwa njira zazikulu zomwe zimagwiritsidwa ntchito popanga mphasa zokhazikika komanso zosokedwa. Nthawi zambiri, imagwiritsidwa ntchito limodzi ndi kuyenda kosapindika. Kugwiritsa ntchito mphasa zokhazikika ndi mphasa zosokedwa ngati zinthu zopukutidwa kungathandize kwambiri kuti zinthuzo zisamasweke komanso kuti zinthuzo zisasweke. Njira yopukutira imafuna kuti mphasa ikhale ndi ulusi wofanana, mphamvu yolimba kwambiri, kulowa mwachangu kwa resin, kusinthasintha kwabwino komanso kudzaza nkhungu, ndipo mphasa iyenera kukhala ndi kutalika kokhazikika.

RTM:Kuumba Resin Transfer Molding (RTM) ndi njira yopangira nkhungu yotsekedwa. Imapangidwa ndi nkhungu ziwiri, nkhungu yachikazi ndi yachimuna, pampu yokakamiza ndi mfuti yopangira jekeseni, popanda kukanikiza. Njira ya RTM nthawi zambiri imagwiritsa ntchito mphasa zokhazikika komanso zosokedwa m'malo mwa mphasa zodulidwa. Ndikofunikira kuti pepala la mphasa likhale losavuta kudzazidwa ndi utomoni, mpweya wabwino wolowa, kukana bwino kupukuta utomoni komanso kusinthasintha bwino.

Njira yokhotakhota: mphasa zodulidwa za ulusi ndipo mphasa zopitilira nthawi zambiri zimagwiritsidwa ntchito popangira zozungulira ndikupanga zigawo zokhala ndi utomoni wambiri zomwe zimagwiritsidwa ntchito makamaka ngati zinthu, kuphatikiza zigawo zamkati ndi zigawo zakunja. Zofunikira pa mphasa ya ulusi wagalasi poyendetsa zozungulira ndizofanana ndi zomwe zili mu njira yoyikira ndi manja.

Kuumba kwa Centrifugal: mphasa yodulidwa ya ulusinthawi zambiri amagwiritsidwa ntchito ngati zinthu zopangira. Mpando wodulidwa wa chingwe umayikidwa kale mu chikombole, kenakoutomoniimawonjezedwa m'bowo lotseguka la nkhungu, ndipo thovu la mpweya limatulutsidwa ndi centrifugation kuti chinthucho chikhale chokhuthala. Chobowoleracho chikufunika kuti chikhale ndi mawonekedwe osavuta kulowa komanso mpweya wabwino kulowa.

Njira yapadera yopangira matiresi a ulusi wagalasi imatsimikizira kuti ili ndi ubwino wa malo osalala, kufalikira kwa ulusi mofanana, kumva kofewa m'manja, kulowa bwino kwa mpweya, komanso liwiro lolowera mwachangu kwa utomoni. Mafotokozedwe ake ndi kuyambira 15g/m² mpaka 100g/m². Zigawo ndi zipolopolo ndizofunikira kwambiri pa mapaipi a FRP ndi zinthu za FRP.
