Kuyika manja ndi njira yosavuta, yotsika mtengo komanso yothandiza yopangira zinthu za FRP yomwe siifuna zida zambiri komanso ndalama zoyambira ndipo ingathandize kupeza phindu pakapita nthawi yochepa.

1. Kupopera ndi kupaka utoto wa gel coat

Pofuna kukonza ndikukongoletsa mawonekedwe a pamwamba pa zinthu za FRP, kuwonjezera mtengo wa chinthucho, ndikuwonetsetsa kuti gawo lamkati la FRP silikuwonongeka ndikuwonjezera moyo wa ntchito ya chinthucho, pamwamba pa chinthucho nthawi zambiri pamakhala wosanjikiza wokhala ndi utoto wa pigment (mtundu wa phala), kuchuluka kwa utomoni wothira, ukhoza kukhala utomoni woyera, komanso wowonjezeredwa ndi mawonekedwe a pamwamba. Gawoli limatchedwa gel coat layer (lomwe limatchedwanso surface layer kapena decorative layer). Ubwino wa gel coat layer umakhudza mwachindunji ubwino wakunja kwa chinthucho komanso kukana nyengo, kukana madzi ndi kukana kukokoloka kwa mankhwala, ndi zina zotero. Chifukwa chake, mfundo zotsatirazi ziyenera kukumbukiridwa popopera kapena kupaka utoto wosanjikiza wa gel coat.

2. Kudziwa njira yoyendetsera ntchito

Njira yopangira zinthu imagwirizana ndi zinthu zosiyanasiyana monga mtundu wa chinthu, mtengo wa chinthu, ndi nthawi yopangira (kuchuluka kwa zinthu). Chifukwa chake, musanakonze kupanga, ndikofunikira kumvetsetsa bwino momwe zinthu zilili (chilengedwe, kutentha, pakati, katundu ……, ndi zina zotero), kapangidwe ka chinthu, kuchuluka kwa zinthu zomwe zapangidwa, ndi momwe zimamangidwira pamene chinthucho chikugwiritsidwa ntchito, komanso mutafufuza ndi kufufuza, kuti mudziwe njira yopangira zinthu, nthawi zambiri, mfundo zotsatirazi ziyenera kuganiziridwa.

3. Zomwe zili mu kapangidwe ka ndondomeko

(1) Malinga ndi zofunikira zaukadaulo za chinthucho, kusankha zipangizo zoyenera (zipangizo zolimbitsa, zipangizo zomangira ndi zipangizo zina zothandizira, ndi zina zotero). Posankha zipangizo zopangira, mfundo zotsatirazi zimaganiziridwa kwambiri.

①Kaya chinthucho chikukhudzana ndi asidi ndi alkaline, mtundu wa chinthucho, kuchuluka kwake, kutentha komwe chikugwiritsidwa ntchito, nthawi yomwe chikugwiritsidwa ntchito, ndi zina zotero.

②Kaya pali zofunikira pa ntchito monga kufalitsa kuwala, choletsa moto, ndi zina zotero.

(3) Kusankha chotulutsira.

(4) Dziwani momwe utomoni umagwirizanirana ndi makina ake ophikira utomoni.

(5) Malinga ndi makulidwe ndi mphamvu ya chinthu chomwe chaperekedwa, dziwani mitundu yosiyanasiyana ya zinthu zolimbikitsira, zofunikira, chiwerengero cha zigawo ndi njira yoyika zigawozo.

(6) Kukonzekera njira zokonzera zinthu.

4. Dongosolo la phala la pulasitiki lolimbikitsidwa ndi ulusi wagalasi

Kuyika manja ndi njira yofunika kwambiri yopangira phala la pamanja, kuyenera kugwiritsidwa ntchito bwino kuti mupeze utomoni wolondola, wolondola, wopanda thovu loonekera bwino, wopanda kuyikapo thovu loipa, wopanda kuwonongeka kwa ulusi ndi pamwamba pa chinthucho, kuti muwonetsetse kuti zinthuzo ndi zabwino. Chifukwa chake, ngakhale kuti ntchito yomatira ndi yosavuta, sikophweka kupanga zinthuzo bwino, ndipo ziyenera kuonedwa mozama.

(1) Kulamulira makulidwe

Ulusi wagalasiKuwongolera makulidwe a zinthu zapulasitiki zolimbikitsidwa, ndi kapangidwe ka njira yopangira ndi kupanga komwe kudzakumana ndi mavuto aukadaulo, tikadziwa makulidwe ofunikira a chinthu, ndikofunikira kuwerengera kuti tidziwe utomoni, kuchuluka kwa zodzaza ndi zinthu zolimbikitsira zomwe zimagwiritsidwa ntchito muzofotokozera, kuchuluka kwa zigawo. Kenako werengani makulidwe ake oyerekeza motsatira njira yotsatirayi.

(2) Kuwerengera mlingo wa utomoni

Mlingo wa resin wa FRP ndi gawo lofunikira la njira, lomwe lingawerengedwe pogwiritsa ntchito njira ziwiri zotsatirazi.

A yowerengedwa motsatira mfundo yodzaza mipata, njira yowerengera kuchuluka kwa utomoni, imangodziwa kulemera kwa dera la nsalu yagalasi ndi makulidwe ofanana (wosanjikiza wagalasiulusinsalu mofanana ndi makulidwe a chinthucho), mutha kuwerengera kuchuluka kwa utomoni womwe uli mu FRP

B imawerengedwa poyamba powerengera kulemera kwa chinthucho ndikupeza kuchuluka kwa ulusi wagalasi.

(3)Galasiulusidongosolo lopaka nsalu

Zogulitsa zokhala ndi gelcoat layer, gelcoat sizingasakanizidwe ndi zinthu zodetsa, ndipo phala liyenera kuyikidwa musanayambe dongosolo kuti lisawononge kuipitsidwa pakati pa gelcoat layer ndi backward layer, kuti lisayambitse kusagwirizana pakati pa zigawo, ndikukhudza ubwino wa zinthu. Gel coat layer ikhoza kuwonjezeredwa ndipamwambamphasaDongosolo la phala liyenera kulabadira kulowetsedwa kwa ulusi wagalasi, choyamba kupanga kulowa kwa ulusi wa resin pamwamba pa chikwama cha ulusi, kenako kupanga mpweya mkati mwa chikwama cha ulusi kusinthidwa kwathunthu ndi ulusi. Ndikofunikira kwambiri kuonetsetsa kuti gawo loyamba la zinthu zolimbitsa ladzazidwa kwathunthu ndi ulusi ndipo limayikidwa bwino, makamaka pazinthu zina zomwe zingagwiritsidwe ntchito kutentha kwambiri. Kulowetsedwa koyipa komanso kupendekera koyipa kumatha kusiya mpweya mozungulira chikwama cha gelcoat, ndipo mpweya wotsalawu ungayambitse thovu la mpweya panthawi yokonza ndikugwiritsa ntchito mankhwalawa chifukwa cha kutentha kwakukulu.

Dongosolo loyika manja, choyamba mu gawo la gel coat kapena pamwamba popanga nkhungu ndi burashi, scraper kapena impregnation roller ndi chida china chopaka manja chophimbidwa mofanana ndi wosanjikiza wa utomoni wokonzedwa, kenako ikani wosanjikiza wa zinthu zolimbitsa (monga mizere yopingasa, nsalu yopyapyala kapena pamwamba pake, ndi zina zotero), kutsatiridwa ndi zida zopangira zidzaphwanyidwa bwino, kukanikiza, kuti zigwirizane bwino, ndikusamala kuti zisatulutse thovu la mpweya, kuti nsalu yagalasi ikhale yodzaza mokwanira, osati zigawo ziwiri kapena zingapo za zinthu zolimbitsa nthawi imodzi. Bwerezani ntchito yomwe ili pamwambapa, mpaka makulidwe ofunikira ndi kapangidwe kake.

Ngati mawonekedwe a chinthucho ndi ovuta kwambiri, malo ena pomwe zinthu zolimbikitsira siziyikidwa bwino, thovu silili losavuta kuchotsa, lumo lingagwiritsidwe ntchito kudula malowo ndikupangitsa kuti likhale lathyathyathya, ziyenera kudziwika kuti gawo lililonse liyenera kukhala magawo ozungulira a chodulidwacho, kuti asatayike mphamvu.

Pazigawo zomwe zili ndi ngodya inayake, zitha kudzazidwa ndiulusi wagalasi ndi utomoni. Ngati mbali zina za chinthucho ndi zazikulu, zitha kukhuthala kapena kulimbitsa bwino m'derali kuti zikwaniritse zofunikira pakugwiritsa ntchito.

Popeza kuti ulusi wa nsalu umasiyana, mphamvu yake imasiyananso.nsalu yagalasi ya ulusinjira yoikira iyenera kutsatiridwa malinga ndi zofunikira pa ndondomekoyi.

(4) kukonza msoko wa pakhosi

Musamadule ulusi womwewo mosalekeza momwe mungathere, pewani kudula kapena kulumikiza mosasankha, koma chifukwa cha kukula kwa chinthucho, zovuta zake ndi zifukwa zina zomwe zingalepheretse, dongosolo la phala lingatengedwe pamene matako akuyikidwa, msoko wa lap uyenera kuzunguliridwa mpaka phala lifike pa makulidwe omwe amafunikira ndi chinthucho. Mukamamatira, utomoni umalowetsedwa ndi zida monga maburashi, ma rollers ndi ma bubble roller ndipo ma bubble ampweya amachotsedwa.

Ngati mphamvu ya chinthucho ndi yokwera, kuti zitsimikizire kuti chinthucho chili ndi mphamvu, cholumikizira cha lap chiyenera kugwiritsidwa ntchito pakati pa nsalu ziwiri, m'lifupi mwa cholumikizira cha lap ndi pafupifupi 50 mm. Nthawi yomweyo, cholumikizira cha lap cha gawo lililonse chiyenera kuzunguliridwa momwe zingathere.

(3)Kuyika manjayachingwe chodulidwa mphasas 

Mukagwiritsa ntchito felt yodulidwa mwachidule ngati chinthu cholimbikitsira, ndibwino kugwiritsa ntchito ma roller a impregnation a kukula kosiyana kuti mugwiritse ntchito, chifukwa ma roller a impregnation ndi othandiza kwambiri pochotsa thovu mu utomoni. Ngati palibe chida chotere ndipo impregnation ikufunika kuchitidwa ndi burashi, utomoni uyenera kugwiritsidwa ntchito pogwiritsa ntchito njira ya point brush, apo ayi ulusiwo udzasokonekera ndikusunthika kotero kuti kufalikira sikofanana ndipo makulidwe ake sali ofanana. Zipangizo zolimbikitsira zomwe zimayikidwa mu ngodya yakuya yamkati, ngati burashi kapena impregnation roller ndizovuta kuti igwirizane bwino, ikhoza kukonzedwa bwino ndikukanikiza ndi dzanja.

Mukapereka malo okonzera, gwiritsani ntchito chopukutira guluu kuti muyike guluu pamwamba pa nkhungu, kenako ikani mphasa yodulidwayo pamanja. Ikani chidutswa pa chikombolecho ndikuchikonza bwino, kenako gwiritsani ntchito chokulungira cha guluu pa guluu, mobwerezabwereza mutembenuzireni kumbuyo ndi mtsogolo, kuti guluu wa resin alowe mu mphasa, kenako gwiritsani ntchito chokulungira cha guluu kuti mufinye guluu mkati mwa mphasa pamwamba ndikutulutsa thovu la mpweya, kenako phatikizani gawo lachiwiri. Ngati mufika pakona, mutha kung'amba mphasa ndi dzanja kuti muzitha kukulunga bwino, ndipo kutalika pakati pa zidutswa ziwiri za mphasa ndi pafupifupi 50mm.

Zinthu zambiri zingagwiritsenso ntchitomphasa zodulidwa za ulusindi nsalu yagalasi yopangira nsalu, monga momwe makampani aku Japan amapangira bwato la usodzi pogwiritsa ntchito njira ina yopangira, akuti njira yopangira zinthu za FRP ndi yabwino.

(6) Dongosolo la phala la zinthu zokhala ndi makoma okhuthala

Zinthu zokhala ndi makulidwe osakwana 8 mm zitha kupangidwa kamodzi, ndipo ngati makulidwe a chinthucho ndi oposa 8 mm, ziyenera kugawidwa m'mapangidwe angapo, apo ayi chinthucho chidzachiritsidwa chifukwa cha kutentha kochepa komwe kungayambitse kutentha, kusintha mtundu, zomwe zimakhudza magwiridwe antchito a chinthucho. Pazinthu zomwe zili ndi mapangidwe angapo, ma burrs ndi thovu zomwe zimapangidwa pambuyo pa phala loyamba ziyenera kuchotsedwa musanapitirize kuyika panjira yotsatira. Nthawi zambiri, tikulimbikitsa kuti makulidwe a chopangira chimodzi asapitirire 5mm, koma palinso ma resin otsika kutentha komanso ma resin ochepa omwe amapangidwa kuti apangire zinthu zokhuthala, ndipo makulidwe a resin iyi ndi akulu pa chopangira chimodzi.
