nkhani

Njira ya RTM ili ndi ubwino wachuma chabwino, kupangika bwino, kutsika kochepa kwa styrene, kulondola kwapamwamba kwa chinthucho ndi khalidwe labwino la pamwamba mpaka kalasi A pamwamba.
Njira yopangira RTM imafuna kukula kolondola kwa nkhungu. rtm nthawi zambiri amagwiritsa ntchito yin ndi yang kutseka nkhungu, chifukwa chake cholakwika cha kukula kwa nkhungu ndikuwongolera ndendende makulidwe a patsekeke pambuyo potseka nkhungu ndi nkhani yayikulu.

1, kusankha zinthu
Kuwongolera kulondola kwa nkhungu, kusankha kwa zida ndizofunikira kwambiri. Kupanga kwaMtengo wa RTMamagwiritsidwa ntchito mu odula nkhungu gel osakaniza ayenera kukhala ndi kulimba kwambiri, kukana kutentha kwambiri ndi kuchepa kochepa, nthawi zambiri angagwiritsidwe ntchito vinyl ester mtundu nkhungu gel osakaniza odula.
RTM nkhungu utomoni zambiri amafuna wabwino kukana kutentha ndi kuuma, mlingo winawake wa kulimba, shrinkage ndi yaing'ono kapena kuyandikira ziro shrinkage.RTM nkhungu ndi zipangizo CHIKWANGWANI reinforcement angagwiritsidwe ntchito 30g / ㎡ sanali alkali pamwamba anamva ndi 300g / ㎡ sanali alkali short-cut anamva. Ndi 300g/m sanali alkali short-cut anamva kuposa 450g/m sanali alkali short-cut anamva wa nkhungu shrinkage ndi m'munsi, apamwamba dimensional kulondola.

2, Kuwongolera njira
Kusankhidwa kwa zinthu zopangira ndikuwongolera kukula kwa nkhungu ya RTM ndi makulidwe amkati a ulalo wofunikira, ndipo munjira yosinthira nkhungu nthawi iliyonse kuwongolera kwaubwino ndi njira yofunika kwambiri. Ngati ndondomekoyi kulamulira si koyenera, ngakhale zopangira akukumana ntchito zofunika, n'zovuta kutembenuza nkhungu ndi miyeso yolondola ndi oyenerera patsekeke makulidwe.
Kutembenuza nkhungu kumayenera kumvetsetsa kaye kusinthika kwa nkhungu. Pofuna kuonetsetsa mwatsatanetsatane, mu chiyambi cha fyuluta nkhungu nkhungu kapangidwe angagwiritsidwe ntchito malinga ndi nkhungu shrinkage mlingo kusiya kuchuluka kwa shrinkage chilolezo. Komanso, chidwi ayenera kuperekedwa kwa kusintha kwa pamwamba pa nkhungu nkhungu kukonza lathyathyathya, nkhungu nkhungu pamwamba scarring ayenera kukumba kunja. Zipsera ndi kutsika kwamitengo sikufanana kumapangitsa kuti pamwamba pa nkhungu ya fiberglass pasakhale lathyathyathya. Chotsani zipserazo ndikuchotsani zipsera, pamwamba pa nkhungu ziyenera kupukuta, zomwe zimafunika kukwapula 2-3. Putty ikachiritsidwa, gwiritsani ntchito sandpaper kupukuta pamwamba mpaka itakwaniritsa kukula ndi mawonekedwe ake molondola.
Matabwa nkhungu kupanga ayenera kukhala wokonzeka kuthera khama, chifukwa ambiri, dimensional kulondola kwaFRP nkhungu pamapeto pakezimadalira kulondola kwa nkhungu yamatabwa. Pofuna kuonetsetsa kuti pamwamba pa galasi CHIKWANGWANI analimbitsa nkhungu pulasitiki ndi yosalala ndi woyera, kutembenukira chidutswa choyamba cha galasi CHIKWANGWANI analimbitsa nkhungu pulasitiki, gel osakaniza odula wosanjikiza ntchito njira kutsitsi ndi koyenera kwambiri.
Kupopera gelcoat ayenera kulabadira kusintha mpweya wa mfuti, kuti gelcoat utomoni atomization ndi yunifolomu, sasonyeza particles. Mfuti yopopera ndi mfuti ziyenera kukhala kunja kwa nkhungu, kuti zisapangitse malaya am'deralo kupachikidwa, zomwe zimakhudza mawonekedwe a pamwamba. Pambuyo gel osakaniza wosanjikiza kuchiritsidwa, muiike pamwamba anamva. Pamwamba payenera kukhala kunja kwa nkhungu, kuti zisapangitse gelcoat wamba kupachikidwa, zomwe zimakhudza mawonekedwe a pamwamba.
Pambuyo pochiritsa gel osakaniza, sungani pamwamba pake, kumverera kwapamwamba kuyenera kuphimbidwa ndi lathyathyathya, lopindika kapena lamba liyenera kudulidwa ndikukonzedwa. Amamatira bwino pamwamba anamva, burashi akhoza choviikidwa mu utomoni pang'ono kuti zilowerere pamwamba anamva, kulabadira kulamulira kuchuluka kwa guluu, kuti athe mokwanira kuloŵa CHIKWANGWANI, koma osati kwambiri. Mkulu zomatira zili, kuwira si kophweka kusaganizira, ndi chifukwa kuchiritsa exothermic lalikulu, lalikulu shrinkage. Pamwamba anamva wosanjikiza utomoni kuchiritsa kutola thovu, kunyamula thovu sangathe kudula mwa gel osakaniza odula wosanjikiza.
Pambuyo kutola thovu, mchenga woyenera, chotsani fiberglass burrs ndikuchotsa fumbi loyandama, phala lamanja la 300g / m² losagwiritsa ntchito alkali lalifupi, nthawi iliyonse 1 ~ 2 zigawo za phala, kuti muchiritsidwe pambuyo pa nsonga yotentha musanapitilize kumata. Matani kuti makulidwe chofunika, mukhoza kuyala chitoliro mkuwa, ndi kuyala kutchinjiriza pachimake chipika. Kusinthasintha kwa galasi mikanda utomoni putty, monga atagona matenthedwe kutchinjiriza pachimake chipika zomatira, amene kudzaza kusiyana pakati pa matenthedwe kutchinjiriza pachimake chipika.
Pambuyo kuyala, galasi bead putty ayenera kugwiritsidwa ntchito kusalaza kusiyana pamwamba pa insulation core chipika. Insulation core chipika wosanjikiza kuchiritsa ndiyeno muiike 3 ~ 4 zigawo za shortcut-cut, mutha kuyika chigoba chachitsulo cha nkhungu. Mangani mafupa achitsulo, mafupa achitsulo omwe amayamba kutsekedwa kuti athetse kupsinjika kwa kuwotcherera, ndi mafupa achitsulo ndi kusiyana pakati pa nkhungu ziyenera kudzazidwa kuti zisawonongeke.Mtengo wa FRPdeformation ya nkhungu ndi mafupa achitsulo.
Chidutswa choyamba cha nkhungu chikachiritsidwa, nkhungu imachotsedwa, m'mphepete mwa ndegeyo imachotsedwa, nkhungu imatsukidwa ndi zinyalala, ndipo pepala la sera limayikidwa. Kukhuthala kwa pepala logwiritsidwa ntchito kuyenera kukhala kofanana ndipo kutalika kwake kukhale kochepa. Phula la sera liyenera kukulungidwa mu thovu la mpweya, pakakhala thovu la mpweya, lichotsedwe ndikuliikanso kuti liwonetsetse kukula kwa nkhungu. Zolumikizira m'miyendo ziyenera kudulidwa, ndipo mipata pakati pa sera iyenera kusanjidwa ndi putty kapena simenti ya mphira. Pambuyo popaka phula, nkhungu yachiwiri ikhoza kutembenuzidwa mofanana ndi nkhungu yoyamba. Chikombole chachiwiri chimapangidwa pambuyo popopera gelcoat, ndipo mabowo a jekeseni ndi mabowo otulutsa mpweya ayenera kukonzedwa. Tembenukirani chidutswa chachiwiri cha nkhungu, choyamba muyenera kuchotsa m'mphepete zouluka, weld ndi zikhomo malo ndi zotsekera mabawuti, kuti bwino anachiritsa pambuyo demolding.

3, Kuwunika kwa nkhungu ndi njira zowongolera
Mukatha kugwetsa ndi kuyeretsa, gwiritsani ntchito simenti ya mphira kuyeza makulidwe a nkhungu. Ngati makulidwe ndi kukula kungakwaniritse zofunikira, ndiye kuti mutatha kupukuta ndi kupukuta, nkhungu ya RTM idzatembenuzidwa bwino ndipo ikhoza kuperekedwa kwa kupanga. Ngati mayeso, chifukwa osauka ndondomeko kulamulira ndi zifukwa zina chifukwa cha nkhungu patsekeke sagwirizana ndi zofunika, zidutswa, kachiwiri kutsegula nkhungu ndi chisoni kwambiri.
Malinga ndi zochitika, pali njira ziwiri:
① adadula nkhungu imodzi, tsegulaninso chidutswa;
② kugwiritsa ntchito njira ya RTM yokha kukonza mawonekedwe a nkhungu, nthawi zambiri chidutswa cha nkhungu pamwamba pa gelcoat wosanjikiza chodulidwa, choyikidwa pagalasi CHIKWANGWANI analimbitsa zakuthupi, chidutswa china cha nkhungu abikidwa pa pepala sera, utsi gelcoat, ndiyeno jekeseni nkhungu, kuchiritsidwa pambuyo processing nkhungu, akhoza kuperekedwa kwa ntchito.
