Inqubo ye-RTM inezinzuzo zomnotho omuhle, ukubonwa okuhle, ukuguquguquka okuphansi kwe-styrene, ukunemba okuphezulu komkhiqizo kanye nekhwalithi enhle ebusweni obusezingeni eliphezulu kuya kwele grade.
Inqubo yokubumba ye-RTM idinga usayizi onembe kakhudlwana wokubumba. I-RTM ngokuvamile isebenzisa i-yin ne-yang ukuvala isikhunta, ngakho-ke iphutha elingusayizi lokubumba nokulawulwa okuqondile kokuqina kwe-cavity ngemuva kokuvala isikhunta yinkinga ebalulekile.
1, Ukukhetha kwezinto ezibonakalayo
Ukulawula ukunemba kokubumba, ukukhethwa kwezinto ezisetshenziswayo kuyinto ebalulekile. Ukukhiqizwa kweI-RTM isikhuntaKusetshenziswe egqoke ijazi le-mold gel kufanele kube nokuqina okunomthelela omkhulu, ukumelana nokushisa okuphezulu kanye nokushiswa okuphansi, ngokuvamile kungasetshenziswa uhlobo lwe-vinyl ester uhlobo lwengubo yokubumba.
I-RTM Mold Resin ngokuvamile nayo idinga ukumelana nokushisa okuhle nokuqina, ukuqina kwethonya kuncane noma kusondelene ne-zero surminkage Izinto zokuqina ze-30g Nge-300g / m - i-non-alkali-cut-cut-cut-cut cut-cut emfishane kune-450g / m non-alkali-cut-cut cut-cut okuzwakele ezenziwe nge-mold shrinkage ingaphansi, ukunemba kobukhulu obuphakeme.
2, Ukulawulwa Kwenqubo
Ukukhethwa kwezinto zokwenziwa okungavuthiwe ukulawula usayizi we-RTM isikhunta kanye nokuqina kwesixhumanisi esibalulekile, futhi inqubo yokuguqula isikhunta nganoma yisiphi isikhathi ukulawulwa kwekhwalithi okubaluleke kakhulu. Uma lokhu kulawulwa kwenqubo kungafanele, noma ngabe impahla eluhlaza ihlangabezana nokusetshenziswa kwezidingo, kunzima ukuvula isikhunta ngobukhulu obunembile kanye nobukhulu obufanele.
Inqubo yokuguqula isikhunta kufanele iqale iqonde ukunemba kwezinkuni zokhuni lwenguquko. Ukuze uqinisekise ukunemba, ekuqaleni kokwakheka kwezihlungi Ngaphezu kwalokho, ukunakwa kufanele kukhokhwe kuguquko lwendawo yokulungisa izinkuni ukulungisa, ukudonsa okubumba inkunzi kumele kuphulwe. Izibazi nezinkuni ze-shrinkage azihambelani zizokwenza ukuthi ingaphezulu le-fiberglass isikhunta alisicaba. Beka izibazi bese ususa ama-burrs angaphezulu, ingaphezulu lesibumba sezinkuni kufanele likhanyele ukwelashwa kwama-putty, ngokuvamile kudingeka ukuklebhula amahlandla ama-2 ~ 3. Ngemuva kokuthi i-Putty yelaphekile, sebenzisa iSandpaper ukuPhalisa ingaphezulu kuze kube yilapho ihlangabezana ngokuphelele nosayizi kanye nezidingo zokunemba.
Ukukhiqizwa kokubumba kokhuni kumele zizimisele ukuchitha umzamo, ngoba ngokuvamile, ukunemba okubucayi kweFrP isikhunta ekugcinenikuya ngokunemba kwesikhunta sokhuni. Ukuze uqinisekise ukuthi ingaphezulu lesigaxa se-fiber fiber aqinisiwe libushelelezi futhi lihlanzekile, liguqula ucezu lokuqala lwe-fiber fiber aqiniswe isikhunta sepulasitiki, ungqimba wengubo ye-gel usebenzisa indlela yokufafaza kufanelekile.
Ukufafaza i-gelcoat kufanele unake ukuguqula ukugeleza komoya kwesibhamu, ukuze i-gelcoat resin atomization iyunifomu, ayikhombisi izinhlayiya. Isibhamu esifafaza isibhamu nesibhamu kufanele kube ngaphandle kwesikhunta, ukuze singabangeli ijazi le-GEL lendawo elenga, lithinta ikhwalithi ephezulu. Ngemuva kokuthi ungqimba wengubo yejeli ephulukiswa, unamathisela ebusweni. Ingaphezulu lazizwa kufanele libe ngaphandle kwesikhunta, ukuze lingabingeli i-gelcoat yendawo, ithinta ikhwalithi ephezulu.
Ngemuva kokuthi ungqimba we-gel coat welashwa, unamathisele ubuzwe obuzwakala, ingaphezulu lalizwakala kufanele limbozwe ngeflethi, eligoqiwe noma i-lap kumele linqunywe futhi linqunywe. Namathela ebusweni obuhle, ukuxubha kungafakwa ngenani elincane le-resin ukucwilisa ngaphezulu komunwe obuzwayo, unake ukulawula kwenani le-glue, kodwa hhayi kakhulu. Okuqukethwe okuphezulu okuphezulu, i-bubble akulula ukuyikhipha, futhi ibangele elapha ama-empothermic amakhulu, i-shrinkage enkulu. I-Surface Farmer Layer Resin ephulukayo ukuze ukhethe ama-bubble, ama-bubble akhetha awakwazi ukusika ungqimba lwejazi le-gel.
After picking bubbles, appropriate sanding, remove fiberglass burrs and remove floating dust, hand-paste 300g / m² non-alkali short-cut felt, each time only 1 ~ 2 layers of paste, to be cured after the exothermic peak before you can continue to paste. Namathisela ubukhulu obudingekayo, ungabeka ipayipi lethusi, bese ubeka ukufakwa okuyisisekelo okuyisisekelo. Ukushintshwa kwengilazi ubuhlalu Resin Putty, njengoba ukubekwa komthamo okushisa okushisayo okunamahloni okunamathela, lapho okufanele ugcwalise khona igebe phakathi kokufakwa okuyisisekelo kwe-thermal.
Ngemuva kokulala, ingilazi bead putty kufanele isetshenziselwe ubushelelezi igebe ebusweni be-infation core block. Ukufakelwa okuyisisekelo sokufakelwa kwesendlalelo se-ungqimba bese unamathisela izingqimba ezi-3 ~ 4 zokusika okufushane, unganamathisela amathambo ensimbi yokubumba. Namatha amathambo ensimbi, amathambo ensimbi aqala ukunxuswa ukuqeda ukucindezela kwe-welding, kanye namathambo ensimbi kanye negebe phakathi kokubumba kufanele kugcwaliswe ukuvikelaJikisanaUkuguqulwa kwesikhunta nge-skeleton yensimbi.
Ngemuva kokusulwa kwesiqephu sokuqala, isikhunta siyasuswa, kususwa umphetho ngokweqile ondizayo Ubukhulu beshidi le-wax elisetshenzisiwe kufanele bube yunifomu futhi ukunwebeka kufanele kube okuncane. Ishidi le-wax akufanele lisongwe kuma-bubble amoya, lapho kukhona ama-bubble omoya, kufanele lisuswe futhi linamathiselwe ukuze liqinisekise usayizi we-caver yombumba. Amalunga we-Lap kufanele asikwe, futhi izikhala phakathi kwamashidi e-wax kufanele afakwe ngesimende noma injoloba. Ngemuva kokuthi ishidi le-wax lisetshenzisiwe, isikhunta sesibili singaphendulwa ngendlela efanayo nesibungu sokuqala. Isikhunta sesibili sivame ukwenziwa ngemuva kokuthi i-gelcoat ichafazwe, futhi izimbobo zokujova kanye nezimbobo zokushintsha kufanele zihlelwe. Vula ucezu lwesibili lokubumba, kufanele uqale ususe umphetho wendiza, wenqamule izikhonkwane zokubeka izikhonkwane nokukhiya ama-bolts, ukwelashwa ngokuphelele ngemuva kokuba yi-demolding.
3, Ukuhlolwa kokubumba kanye nezinyathelo zokulungisa
Ngemuva kokudilizwa nokuhlanza, sebenzisa usimende werabha ukukala ubukhulu besigaxa somuntu. Uma ubukhulu nosayizi ungahlangabezana nezidingo, khona-ke ngemuva kokuqedwa kwenqubo yokugaya nokupholisa ukuqedwa, isikhunta se-RTM sizophendulwa ngempumelelo futhi singahanjiswa ekukhiqizweni. Uma isivivinyo, ngenxa yokulawulwa kwenqubo okungekuhle nezinye izizathu ezibangelwa yi-caver yohlobo azihlangabezani nezidingo, isikhafu, ukuvula kabusha isikhunta sinesihawu esikhulu kakhulu.
Ngokokuhlangenwe nakho kungaba namakhambi amabili:
① Screet One of the isikhunta, vula kabusha ucezu;
Ukusetshenziswa kwenqubo ye-RTM uqobo ukuze kulungiswe izici zesikhunta, imvamisa ucezu lwesikhunta se-gelcoat ungqimba oluvuthiwe, lubeke khonaIzinto eziqinisiwe ze-Glass fiber, elinye isigaxa linamathiselwe ephepheni le-wax, i-gelcoat ye-spray, bese kuthi umjovo wokubumba, ukwelashwa ngemuva kokucutshungulwa kokubumba, kungahanjiswa ekusebenziseni.
