Njira ya RTM ili ndi ubwino wokhala ndi zinthu zabwino, kapangidwe kake kabwino, kusinthasintha kochepa kwa styrene, kulondola kwakukulu kwa chinthucho komanso khalidwe labwino la pamwamba mpaka pamwamba pa grade A.
Njira yopangira RTM imafuna kukula kolondola kwa nkhungu. Nthawi zambiri rtm imagwiritsa ntchito yin ndi yang kutseka nkhungu, kotero cholakwika cha kukula kwa nkhungu ndi kuwongolera molondola makulidwe a m'mimba mutatseka nkhungu ndi vuto lalikulu.

1, Kusankha zinthu
Kuti muwongolere kulondola kwa nkhungu, kusankha zipangizo zopangira ndi chinthu chofunikira. Kupanga kwaRTM nkhunguChovala cha gel chomwe chimagwiritsidwa ntchito mu nkhungu chiyenera kukhala ndi kulimba kwakukulu, kukana kutentha kwambiri komanso kuchepa pang'ono, nthawi zambiri chingagwiritsidwe ntchito ngati chovala cha gel cha mtundu wa vinyl ester.
Utomoni wa RTM nthawi zambiri umafunanso kukana kutentha bwino komanso kulimba, kulimba kwamphamvu, kufupika kwake kumakhala kochepa kapena kofanana ndi kuchepera. Zinyalala za RTM zokhala ndi zinthu zolimbitsa ulusi zitha kugwiritsidwa ntchito 30g / ㎡ zopanda alkali pamwamba ndi 300g / ㎡ zopanda alkali zazifupi. Ndi 300g / m yopanda alkali zazifupi kuposa 450g / m yopanda alkali zazifupi zopangidwa ndi nkhungu, kulondola kwake kumakhala kotsika, kokwera.

2, Kulamulira njira
Kusankha zipangizo zopangira ndikuwongolera kukula kwa nkhungu ya RTM ndi makulidwe a cholumikizira chofunikira, ndipo mu ndondomeko yotembenuza nkhungu nthawi iliyonse kuwongolera khalidwe ndi njira yofunika kwambiri. Ngati kuwongolera njira iyi sikoyenera, ngakhale ngati zipangizozo zikukwaniritsa zofunikira, zimakhala zovuta kutembenuza nkhungu ndi miyeso yolondola komanso makulidwe oyenerera a cholumikiziracho.
Njira yosinthira nkhungu iyenera choyamba kumvetsetsa kulondola kwa nkhungu yosinthira nkhuni. Pofuna kuonetsetsa kuti ndi yolondola, poyamba pa fyuluta, kapangidwe ka nkhungu ya nkhuni kangagwiritsidwe ntchito malinga ndi kuchuluka kwa nkhungu kuti pasakhale kuchuluka kwa kusowa kwa chitsulo. Kuphatikiza apo, chisamaliro chiyenera kuperekedwa pakusintha kwa pamwamba pa nkhungu ya nkhuni, kukonza nkhungu ya nkhuni kukhale kosalala, mabala a pamwamba pa nkhungu ya nkhuni ayenera kuchotsedwa. Zipsera ndi chitsulo chosasinthasintha zimapangitsa kuti pamwamba pa nkhungu ya fiberglass pasakhale kosalala. Chotsani zipsera ndikuchotsa ma burrs pamwamba, pamwamba pa nkhungu ya nkhuni payenera kuchotsedwa ndi putty, nthawi zambiri pamafunika kukanda kawiri mpaka katatu. Putty ikakonzedwa, gwiritsani ntchito sandpaper kuti mupukute pamwamba mpaka ikwaniritse zofunikira za kukula ndi mawonekedwe.
Kupanga nkhungu yamatabwa kuyenera kukhala kofunitsitsa kugwiritsa ntchito khama, chifukwa nthawi zambiri, kulondola kwaFRP nkhungu pamapeto pakeZimadalira kulondola kwa nkhungu yamatabwa. Kuti muwonetsetse kuti pamwamba pa nkhungu ya pulasitiki yolimbikitsidwa ndi ulusi wagalasi ndi yosalala komanso yoyera, tembenuzani chidutswa choyamba cha nkhungu ya pulasitiki yolimbikitsidwa ndi ulusi wagalasi, ndipo gel coat wosanjikiza pogwiritsa ntchito njira yopopera ndi yoyenera kwambiri.
Kupopera gelcoat kuyenera kusamala posintha kayendedwe ka mpweya wa mfuti, kuti atomization ya gelcoat resin ikhale yofanana, isawonetse tinthu tating'onoting'ono. Mfuti yopopera ndi mfuti ziyenera kukhala kunja kwa nkhungu, kuti zisapangitse kuti gel coat yapafupi ikulendewera, zomwe zingakhudze ubwino wa pamwamba. Pambuyo poti gel coat yakonzedwa, ikani pamwamba pake. Felt ya pamwamba pake iyenera kukhala kunja kwa nkhungu, kuti gelcoat yapafupi isapangitse kuti ikulendewera, zomwe zingakhudze ubwino wa pamwamba pake.
Pambuyo poti gel coat layer yakonzedwa, phatikizani pamwamba pa felt, pamwamba pake payenera kuphimbidwa ndi lathyathyathya, kupindika kapena kudulidwa. Ikani pamwamba pake pa felt yabwino, burashi ikhoza kuviikidwa mu utomoni wochepa kuti ilowerere pamwamba pake, samalani ndi kuchuluka kwa guluu, kuti muzitha kulowa mu ulusi wonse, koma osati kwambiri. Guluu wambiri, thovulo silivuta kuchotsa, ndipo limayambitsa kufooka kwakukulu komanso koopsa. Pansi pake pa felt layer resin yophikira kuti ichotse thovu, thovu lopikira silingathe kudula pakati pa gel coat layer.
Mukatha kutola thovu, konzani bwino, chotsani ma fiberglass burrs ndikuchotsa fumbi loyandama, phatikizani ndi dzanja 300g / m² non-alkali short-cut felt, nthawi iliyonse phatikizani zigawo 1 ~ 2 za phala, kuti muchiritsidwe pambuyo pa exothermic peak musanapitirize kuyika. Ikani mpaka makulidwe ofunikira, mutha kuyika chitoliro cha mkuwa, ndikuyika block yapakati yoteteza. Kusintha kwa mikanda yagalasi resin putty, monga kuyika guluu wapakati woteteza kutentha, womwe ungadzaze mpata pakati pa block yapakati yoteteza kutentha.
Mukamaliza kuika, galasi lopaka utoto liyenera kugwiritsidwa ntchito kusalala mpata pamwamba pa chipika chapakati cha insulation. Chophimba chapakati cha insulation chimapopera kenako chimamatira zigawo zitatu mpaka zinayi za felt yodulidwa mwaufupi, mutha kumata chigoba chachitsulo cha nkhungu. Ikani chigoba chachitsulo, chigoba chachitsulo choyamba chimamatiridwa kuti chichotse kupsinjika kwa welding, ndipo chigoba chachitsulo ndi mpata pakati pa nkhungu ziyenera kudzazidwa kuti zisawonongeke.FRPkusintha kwa nkhungu ndi chigoba chachitsulo.
Chidutswa choyamba cha nkhungu chikatha kukonzedwa, nkhunguyo imachotsedwa, m'mphepete mwake mopitirira muyeso umachotsedwa, m'bowo la nkhungu limatsukidwa zinyalala, ndipo pepala la sera limayikidwa. Kukhuthala kwa pepala la sera lomwe limagwiritsidwa ntchito kuyenera kukhala kofanana ndipo kutalika kwake kuyenera kukhala kochepa. Pepala la sera siliyenera kukulungidwa ndi thovu la mpweya, likangopezeka thovu la mpweya, liyenera kuchotsedwa ndikupakidwanso kuti zitsimikizire kukula kwa bowo la nkhungu. Mapazi olumikizirana ayenera kudulidwa, ndipo mipata pakati pa mapepala a sera iyenera kulinganizidwa ndi putty kapena simenti ya rabara. Pepala la sera litagwiritsidwa ntchito, nkhungu yachiwiri ikhoza kuzunguliridwa mofanana ndi nkhungu yoyamba. Nkhungu yachiwiri nthawi zambiri imapangidwa pambuyo poti gelcoat yapopedwa, ndipo mabowo obayira ndi mabowo otulukira mpweya ayenera kukonzedwa. Tembenuzani chidutswa chachiwiri cha nkhungu, choyamba muyenera kuchotsa m'mphepete mwake, kulumikiza mapini oikira ndi mabotolo otsekera, kuti muchiritsidwe kwathunthu mutachotsa.

3, Kuyang'anira nkhungu ndi njira zothanirana nazo
Mukamaliza kuyeretsa ndi kuchotsa nkhungu, gwiritsani ntchito simenti ya rabara kuti muyese makulidwe a nkhungu. Ngati makulidwe ndi kukula kwake kungakwaniritse zofunikira, ndiye kuti nkhungu ya RTM ikatha, idzatembenuzidwa bwino ndipo ikhoza kuperekedwa kuti ipangidwe. Ngati mayeso, chifukwa cha kusayang'anira bwino njira ndi zifukwa zina zomwe zimachitika chifukwa cha nkhungu, sizikukwaniritsa zofunikira, ndipo zinyalala, kutsegulanso nkhunguyo ndi chisoni chachikulu.
Malinga ndi zomwe zachitika, pali njira ziwiri zothetsera vutoli:
1. Ndinachotsa chimodzi mwa nkhungu, ndinatsegulanso chidutswacho;
② Kugwiritsa ntchito njira ya RTM yokha kukonza mawonekedwe a nkhungu, nthawi zambiri chidutswa cha pamwamba pa nkhungu chimachotsedwa, ndikuyikidwa pagalasi ulusi wolimbitsa zinthu, chidutswa china cha nkhungu chimamangiriridwa pa pepala la sera, gelcoat yopopera, kenako jakisoni wa nkhungu, kuti uchiritsidwe pambuyo pokonza nkhungu, ukhoza kuperekedwa kuti ugwiritsidwe ntchito.
