Yankho:
Pangani ndondomeko yoyenera ya zinthu ndikupopera mofanana.
3. Kutalikirana kwa mizere (osamatira)
chifukwa:
Sera yopukutira yosakwanira, zotulutsa za silicone zimakhala ndi malo owonekera, ndipo madzi kapena mafuta amasakanizidwa popopera mbewu mankhwalawa.
Yankho:
Mukapukuta bwino sera, pukutani nthawi yomweyo mpaka itawala, gwiritsani ntchito sera kapena nkhungu yotulutsa bwino pazopangira ndi zopangira, gwiritsani ntchito mpweya wouma, ndikuyika cholekanitsa madzi amafuta.
4. Thupi lachilendo losakanikirana
chifukwa:
Ziphuphu zazing'ono ndi matupi akunja mu malaya a gel osakaniza, dothi pamwamba pa nkhungu, tizilombo touluka mu spray ndi fumbi mu msonkhano wopanga.
Yankho:
Mukamagwiritsa ntchito malaya osankhidwa a gel osakaniza, nkhungu iyenera kutsukidwa ndikutsukidwa musanapope malaya a gel osakaniza, ndipo magetsi osasunthika pamwamba pa nkhungu ayenera kuchotsedwa pansi pamikhalidwe kuti tipewe kulowerera kwa tizilombo touluka ndikusunga msonkhano wanu wopanga.
5. wokhwinyata
chifukwa:
Kukhuthala kwa gawo loyamba la gelcoat mukatsuka sikokwanira, nthawi pakati pa kutsuka gelcoat (nthawi ziwiri) ndi yayifupi kwambiri, nkhungu kapena gelcoat imakhala ndi chinyezi pakugwiritsa ntchito gelcoat zomwe zimapangitsa kuti gelcoat iwonongeke, chinyezi chapantchito ndichokwera kwambiri. kapena kuyanika kosakwanira kwa PVA kapena chowumitsa pang'ono, kuchiritsa pang'onopang'ono kwa gelcoat, kuchiritsa kosiyana kwa gelcoat.
Yankho:
Gwiritsani ntchito mofanana kuti makulidwe a filimu yoyamba ndi 0.2-0.25 mm. Gelcoat ikatha kuchiritsidwa, gwiritsani ntchito gelcoat yachiwiri kapena topcoat ndikugwiritsa ntchito gelcoat pambuyo pa nkhungu youma, kuchepetsa chinyezi kapena kusiya kukonza pazovuta kwambiri. Lolani kuti PVA iume kwathunthu ndikuyika gelcoat. Mlingo wa chowumitsa uyenera kukhala pakati pa 2.5% ndi 1%. Wonjezerani kutentha kwa kuntchito ndikupereka mpweya wabwino kuti mpweya wa styrene ukhalebe mu nkhungu.
6. kugwetsa
chifukwa:
Pambuyo potsuka gelcoat, nkhungu imapunduka panthawi yogwira ntchito ndipo dera lanu lidzatentha. Kuchuluka kwa gelcoat hardener ndikokulirapo, kusiyana kwa kutentha ndikokulirapo. Chophimba chochuluka chotulutsa nkhungu sibwino kuyeretsa. Anasiyidwa motalika kwambiri atapaka chikhoto cha gel osakaniza.
Yankho:
Pogwira, samalani kuti musawononge nkhungu. Mukatenthedwa, nkhungu siyenera kuikidwa pamphepete mwa gwero la kutentha, kuti kusiyana kwa kutentha sikusinthe kwambiri. Pambuyo phula, buff mpaka kuwala. Kugwiritsa Ntchito Release Wax Moyenera Mukapaka gelcoat, iyenera kuyikidwa mkati mwa maola 24.
7. kuwala koyipa
chifukwa:

9. mtundu wosiyana
chifukwa:
Chinyezi chimasakanizidwa mu malaya a gel, kugwedezeka (kupatukana kwa pigment) kumachitika, kupaka kosagwirizana (m'munsi ukhoza kuwonedwa kudzera mu malaya a gel), osakwanira oyambitsa (pigment imalowa mu chidebe). Kusiyidwa motalika kwambiri mutakoka utoto. Mitundu yosakanikirana powonjezera utoto
Yankho:
Sinthani thixotropy wa malaya a gel osakaniza, gwiritsani ntchito mofanana (0.3-0. 5 mm), ndikugwedeza bwino. Mukamagwiritsa ntchito pigment (chovala cha gel), chobvala cha gel chomwe chili mumtsukocho chiyenera kugwedezeka ndi guluu, ndipo malo ogwirira ntchito ayenera kutsukidwa pogwiritsa ntchito malaya a gel, malo osungiramo katundu omwe amaikidwapo ayenera kukhala aukhondo komanso aukhondo.
10. Kusachiritsika bwino
chifukwa:
Mwayiwala kuwonjezera chowonjezera kapena chochiritsira, chothamangitsira pang'ono, kusuntha kosakwanira, kusunga mpweya wa styrene, komanso kutentha pang'ono.
Yankho:
Musanagwiritse ntchito, tsimikizirani ngati accelerator yawonjezedwa. Pambuyo powonjezera mankhwala ochiritsira, ayenera kugwedezeka mokwanira ndi mpweya wabwino kuti awononge mpweya wa styrene womwe uli pansi ndikuwonjezera kutentha kwa malo ogwirira ntchito.
11. zipsera
chifukwa:
Zipsera, zilonda zam'mphepete, kuvulala kotulutsa nkhungu, zotulutsa nkhungu, zotsalira za sera, zizindikiro za PVA brush, zipsera za nkhungu.
Yankho:
Gwirani ntchito mosamala, tetezani katunduyo ndi zinthu zofewa, gwiritsani ntchito makina odulira molondola, gwiritsani ntchito njira yobowolera bwino, gwirani nkhungu mopepuka, konzani nkhungu ndikukonza pafupipafupi, ndikuyika PVA mowonda komanso molingana.
12. kupasuka
chifukwa:
Kugwetsa monyinyirika, mawonekedwe osayenerera, kuwomba (kuphulika kwa kangaude), kusonkhana monyinyirika, kukhazikika kwa nkhawa.
Yankho:
Kambirananinso za njira yochizira yotulutsa ndi mtundu wa wotulutsa, kukonza nkhungu (kuchepetsa kutsetsereka kugawanika kufa), pewani kumenyedwa mwamphamvu, kupakani chojati cha gel mofanana osati chokhuthala kwambiri, kambirananinso kukula kwa chinthu chimodzi, ndikukonzanso. pulogalamu yopangira.
