Inqubo ye-RTM inezinzuzo zokonga okuhle, ukuklanywa okuhle, ukuguquguquka okuphansi kwe-styrene, ukunemba okuphezulu komkhiqizo kanye nekhwalithi enhle yobuso kuze kufike ku-grade A.
Inqubo yokubumba ye-RTM idinga usayizi onembe kakhudlwana wesikhunta. I-rtm ngokuvamile isebenzisa i-yin ne-yang ukuvala isikhunta, ngakho-ke iphutha losayizi wesikhunta kanye nokulawulwa okunembile kobukhulu besikhala ngemva kokuvala isikhunta kuyinkinga ebalulekile.

1, Ukukhetha izinto
Ukulawula ukunemba kwesikhunta, ukukhethwa kwezinto zokusetshenziswa kuyisici esibalulekile. UkukhiqizwaIsikhunta se-RTMIjazi lejeli elisetshenziswa ejazini lesikhunta kufanele libe nokuqina okuphezulu, ukumelana nokushisa okuphezulu kanye nokuncipha okuphansi, ngokuvamile lingasetshenziswa njengejazi lejeli lesikhunta le-vinyl ester.
I-RTM mold resin ngokuvamile idinga ukumelana nokushisa okuhle kanye nokuqina, izinga elithile lokuqina komthelela, ukuncishiswa kuncane noma kusondele ekuncishisweni kwe-zero. Izikhunta ze-RTM ezinezinto zokuqinisa ifayibha zingasetshenziswa i-30g / ㎡ i-non-alkali surface felt kanye ne-300g / ㎡ i-non-alkali short-cut felt. Nge-300g / m i-non-alkali short-cut felt kune-450g / m i-non-alkali short-cut felt eyenziwe nge-mold shrinkage iphansi, inembalo ephezulu.

2, Ukulawulwa kwenqubo
Ukukhethwa kwezinto zokusetshenziswa kulawula usayizi wesikhunta se-RTM kanye nobukhulu besikhala sesixhumanisi esibalulekile, futhi enkambisweni yokujika isikhunta nganoma yisiphi isikhathi ukulawula ikhwalithi kuyinqubo ebaluleke kakhulu. Uma lokhu kulawulwa kwenqubo kungafaneleki, noma ngabe izinto zokusetshenziswa zihlangabezana nezidingo, kunzima ukujika isikhunta ngobukhulu obunembile kanye nobukhulu besikhala obufanelekile.
Inqubo yokuguqula isikhunta kufanele iqale iqonde ukunemba kwesikhunta sokhuni esishintshayo. Ukuze kuqinisekiswe ukunemba, ekuqaleni kokuhlunga, umklamo wesikhunta sokhuni ungasetshenziswa ngokuya ngesilinganiso sokuncipha kwesikhunta ukuze kushiywe inani elithile lemvume yokuncipha. Ngaphezu kwalokho, kufanele kunakwe ukuguqulwa kobuso besikhunta sokhuni, ukulungiswa kwesicaba, izibazi zobuso besikhunta sokhuni kumele zimbiwe. Izibazi kanye nokuncipha kwezinkuni akuhambisani kuzokwenza ukuthi ubuso besikhunta se-fiberglass bungabi yisicaba. Bamba izibazi bese ususa ama-surface burrs, ubuso besikhunta sokhuni kumele bukhuhlwe ngokwelashwa kwe-putty, ngokuvamile kudingeka ukuthi kukhuhlwe izikhathi ezingu-2-3. Ngemva kokuba i-putty isilashiwe, sebenzisa i-sandpaper ukuze upholishe ubuso kuze kube yilapho buhlangabezana ngokugcwele nezidingo zobukhulu kanye nokunemba kwesimo.
Ukukhiqizwa kwesikhunta sokhuni kumele kuzimisele ukuchitha umzamo, ngoba ngokuvamile, ukunemba kobukhuluIsikhunta se-FRP ekugcinenikuncike ekunembeni kwesikhunta sokhuni. Ukuze kuqinisekiswe ukuthi ubuso besikhunta sepulasitiki esiqiniswe ngefayibha yengilazi bubushelelezi futhi buhlanzekile, phendula ucezu lokuqala lwesikhunta sepulasitiki esiqiniswe ngefayibha yengilazi, ungqimba lwejazi lejeli usebenzisa indlela yokufafaza lufaneleka kakhulu.
I-gelcoat yokufutha kufanele inake ukulungisa ukuhamba komoya kwesibhamu, ukuze i-gelcoat resin atomization ifane, ingakhombisi izinhlayiya. Isibhamu sokufutha kanye nesibhamu kufanele kube ngaphandle kwesikhunta, ukuze kungabangela ukulenga kwesikhumba sejeli sendawo, okuthinta ikhwalithi yobuso. Ngemva kokuba ungqimba lwesikhumba sejeli selulungisiwe, namathisela i-surface felt. I-surface felt kufanele ibe ngaphandle kwesikhunta, ukuze kungabangela ukulenga kwesikhumba sejeli sendawo, okuthinta ikhwalithi yobuso.
Ngemva kokuba ungqimba lwejazi lejeli selulungisiwe, namathisela i-felt ebusweni, i-felt ebusweni kufanele imbozwe nge-flat, igoqwe noma i-lap kumele isikwe futhi inqunywe. Namathisela i-felt ebusweni obuhle, ibhulashi lingacwiliswa enanini elincane le-resin ukuze lingene ngaphakathi kwe-felt ebusweni, naka ukulawula inani le-glue, kokubili ukuze likwazi ukungena ngokugcwele ku-fiber, kodwa hhayi kakhulu. Okuqukethwe kwe-glue ephezulu, i-bubble akulula ukuyikhipha, futhi ibangela ukuwohloka okukhulu, okukhulu kwe-exothermic. I-surface felt layer resin ilungisa ukukha amabhamuza, amabhamuza e-pick awakwazi ukusika phakathi kwe-gel coat layer.
Ngemva kokukhetha amabhamuza, ukusantisa kahle, ukususa ama-fiberglass burrs bese ususa uthuli oluntantayo, unamathisele ngesandla i-300g / m² i-felt emfushane enganqunyiwe ye-alkali, isikhathi ngasinye izingqimba ezi-1 ~ 2 zokunamathisela, ukuze kulungiswe ngemva kwe-exothermic peak ngaphambi kokuthi uqhubeke nokunamathisela. Namathisela kubukhulu obudingekayo, ungabeka ipayipi yethusi, bese ubeka i-insulation core block. Ukuguqulwa kwama-glass beads i-resin putty, njengokubekwa kwe-thermal insulation core block adhesive, okugcwalisa ngayo igebe phakathi kwe-thermal insulation core block.
Ngemva kokubeka, i-glass bead putty kufanele isetshenziswe ukushelela igebe ebusweni be-insulation core block. I-insulation core block layer coring bese unamathisela izendlalelo ezi-3 ~ 4 ze-fur-cut felt, unganamathisela i-mold steel skeleton. Namathisela i-steel skeleton, i-steel skeleton iqale i-anneal ukuze kuqedwe ukucindezeleka kokushisela, bese i-steel skeleton kanye negebe eliphakathi kwe-mold kufanele ligcwaliswe ukuze kuvinjelweI-FRPukuguqulwa kwesikhunta ngohlaka lwensimbi.
Ngemva kokuba ingcezu yokuqala yesikhunta isilungisiwe, isikhunta siyasuswa, unqenqema olungaphezulu olundizayo luyasuswa, unqenqema lwesikhunta luyahlanzwa kususwe udoti, bese kufakwa ishidi le-wax. Ubukhulu beshidi le-wax elisetshenzisiwe kufanele bufane futhi ubude kufanele bube buncane. Ishidi le-wax akufanele ligoqwe ngamabhamuza omoya, uma sekunamabhamuza omoya, kufanele lisuswe bese linamathiselwa kabusha ukuqinisekisa ubukhulu bonqenqema lwesikhunta. Amalunga okubopha kufanele asikwe, futhi izikhala phakathi kwamashidi e-wax kufanele zilinganiswe nge-putty noma nge-raber cement. Ngemva kokuba ishidi le-wax selisetshenzisiwe, isikhunta sesibili singaphendulwa ngendlela efanayo nesikhunta sokuqala. Isikhunta sesibili sivame ukwenziwa ngemva kokuba i-gelcoat isifafaziwe, futhi kufanele kuhlelwe imigodi yokujova kanye nemigodi yokungenisa umoya. Phendula ingcezu yesibili yesikhunta, kumele uqale ususe unqenqema olundizayo, ushisele izikhonkwane zokubeka kanye nama-lock bolts, ukuze uphole ngokuphelele ngemva kokudilizwa.

3, Ukuhlolwa kwesikhunta kanye nezinyathelo zokulungisa
Ngemva kokususa nokuhlanza, sebenzisa usimende werabha ukukala ubukhulu bomgodi wesikhunta. Uma ubukhulu nosayizi kungahlangabezana nezidingo, khona-ke ngemva kokuba inqubo yokugaya nokupholisha isiqediwe, isikhunta se-RTM sizophendulwa ngempumelelo futhi singalethwa ekukhiqizweni. Uma ukuhlolwa, ngenxa yokulawulwa kabi kwenqubo kanye nezinye izizathu ezibangelwa umgodi wesikhunta kungahlangabezani nezidingo, imfucumfucu, ukuvula kabusha isikhunta kuyinto edabukisayo kakhulu.
Ngokusho kokuhlangenwe nakho kungaba nezindlela ezimbili zokwelapha:
1. Ngikhuhle enye yesikhunta, ngiphinde ngiyivule;
② ukusetshenziswa kwenqubo ye-RTM ngokwayo ukulungisa izici zesikhunta, ngokuvamile ucezu lwesendlalelo se-gelcoat ebusweni besikhunta lususiwe, lubekwe phezuizinto eziqinisiwe zefayibha yengilazi, enye ingxenye yesikhunta inamathiselwe ephepheni le-wax, i-spray gelcoat, bese kuthi umjovo wesikhunta, ozolashwa ngemva kokucubungula isikhunta, ulethwe ekusetshenzisweni.
