Inkqubo ye-RTM ineenzuzo zoqoqosho olulungileyo, ukucwangciswa kakuhle, ukuguquguquka okuphantsi kwe-styrene, ukuchaneka okuphezulu kwemveliso kunye nomgangatho omhle womphezulu ukuya kwibakala A.
Inkqubo yokubumba i-RTM ifuna ubungakanani obuchanekileyo bokubumba. I-rtm ngokubanzi isebenzisa i-yin kunye ne-yang ukuvala ukungunda, ngoko ke impazamo yobungakanani bokubumba kunye nolawulo oluchanekileyo lobunzima bomgodi emva kokuvala ukubumba ngumba ophambili.

1, Ukukhetha izinto eziphathekayo
Ukulawula ukuchaneka kwesikhunta, ukukhethwa kwezinto eziluhlaza yinto ebalulekileyo. Imveliso yeRTM ngundoesetyenziswa kwidyasi yejeli yokungunda kufuneka ibe nokuqina kwempembelelo ephezulu, ukumelana nobushushu obuphezulu kunye nokushwabana okuphantsi, ngokubanzi ingasetyenziswa i-vinyl ester uhlobo lwedyasi yejeli yokubumba.
I-RTM yokungunda i-resin ngokubanzi ifuna ukuxhathisa ubushushu kunye nokuqina, iqondo elithile lokuqina kwempembelelo, ukushwabana kuncinci okanye kusondele kwi-zero shrinkage.Ukubumba kwe-RTM kunye nezixhobo zokuqinisa ifayibha zingasetyenziswa 30g / ㎡ umphezulu ongeyo-alkali waziva kunye ne-300g / ㎡ ongeyiyo-alkali omfutshane waziva. Kunye 300g / m non-alkali short-cut-cut waziva ngaphezu 450g / m non-alkali short-cut waziva wenza ukushwabana ngundo isezantsi, ukuchaneka eliphezulu dimensional.

2, Ulawulo lwenkqubo
Ukukhethwa kwezinto eziluhlaza kukulawula ubungakanani be-RTM mold kunye nobukhulu be-cavity yekhonkco ebalulekileyo, kwaye kwinkqubo yokuguqula i-mold naliphi na ixesha lokulawula umgangatho yinkqubo ebaluleke kakhulu. Ukuba olu lawulo lwenkqubo alufanelekanga, nangona izinto eziluhlaza zidibana nokusetyenziswa kweemfuno, kunzima ukuguqula isikhunta kunye nemilinganiselo echanekileyo kunye nobukhulu obufanelekileyo bomgodi.
Inkqubo yokuguqula umngundo kufuneka iqale ibambe ukuchaneka kokungunda komthi wenguqu. Ukuze kuqinisekiswe ukuchaneka, ekuqaleni isihluzo soyilo lokungunda iinkuni zingasetyenziswa ngokwenqanaba ukushwabana ngundo ukushiya isixa esithile isibonelelo ukushwabana. Ukongeza, ingqalelo kufuneka ihlawulwe kwinguqu kumphezulu wokulungisa umngundo iinkuni flat, umngundo iinkuni umphezulu scarring kufuneka kugrunjwe ngaphandle. Izikrweqe kunye nokushwabana komthi akuhambelani kuya kubangela ukuba umphezulu we-fiberglass mold ungabi sicaba. Yomba amanxeba kwaye ususe i-surface burrs, umphezulu wesikhunta somthi kufuneka ukhutshiwe unyango lwe-putty, olufunwa ngokubanzi ukukrwela amaxesha angama-2-3. Emva kokuba i-putty iphilisiwe, sebenzisa i-sandpaper ukupolisha umphezulu de ufezekise ngokupheleleyo ubungakanani kunye neemfuno zokuchaneka kobume.
Ukuveliswa komngundo ngokhuni kufuneka kukulungele ukuchitha umzamo, kuba ngokubanzi, ukuchaneka kwe-dimensionalFRP ngundo ekugqibelenikuxhomekeke ekuchanekeni kwesikhunta sokhuni. Ukuze kuqinisekiswe ukuba umphezulu weglasi ifayibha umngundo weplastiki eyomeleziweyo igudileyo kwaye icocekile, vula iqhekeza lokuqala leglasi yefayibha eyomelezwa ngundo lweplastiki, umaleko wejeli wedyasi usebenzisa indlela yokutshiza ifanelekile.
Ukutshiza i-gelcoat kufuneka kuhlawule ingqalelo ekulungiseni ukuhamba komoya kwesibhamu, ukwenzela ukuba i-gelcoat resin atomization ifane, ayibonisi amaqhekeza. Umpu wokutshiza kunye nompu kufuneka ube ngaphandle kwesikhunta, ukuze ungabangeli ijeli yendawo yokuxhoma, echaphazela umgangatho ophezulu. Emva kokuba umaleko wengubo yejeli uphilisiwe, ncamathelisa umphezulu uvakale. Umphezulu uvakale kufuneka ube ngaphandle komngundo, ukuze ungabangeli i-gelcoat yendawo ejingayo, echaphazela umgangatho womphezulu.
Emva kokuba umaleko wengubo yejeli uphilisiwe, ncamathelisa umphezulu ozivayo, umphezulu ozivayo kufuneka ugutyungelwe ngeflethi, usongwe okanye umjikelo kufuneka usikwe kwaye unqunywe. Namathela umphezulu ovakala kakuhle, ibhrashi inokuntywiliselwa kwixabiso elincinci le-resin ukuze ifakwe kumphezulu uvakale, nikela ingqalelo kulawulo lwesixa seglue, zombini ukukwazi ukungena ngokupheleleyo kwifayibha, kodwa hayi kakhulu. Isiqulatho seglue ephezulu, iqamza akulula ukuba lingabandakanyi, kwaye libangela ukunyanga okukhulu, ukushwabana okukhulu. Umphezulu uvakale umaleko weresin ukunyanga ukukhetha amaqamza, amaqamza akakwazi ukusika umaleko wedyasi yejeli.
Emva kokuchola amaqamza, isanti efanelekileyo, susa iifiberglass burrs kwaye ususe uthuli oludadayo, ncamathelisa ngesandla 300g / m² non-alkali short-cut cut-cut, ixesha ngalinye kuphela 1 ~ 2 umaleko wokuncamathelisa, oza kunyangwa emva kwencopho ye-exothermic ngaphambi kokuba uqhubeke nokuncamathelisa. Namathisela ubukhulu obufunekayo, unokubeka umbhobho wobhedu, kwaye ubeke ibhloko engundoqo ye-insulation. Ukumodareyithwa amaso eglasi resin putty, njengoko ukubekwa thermal insulation core block ancamathele, apho ukugcwalisa umsantsa phakathi thermal insulation core block.
Emva kokubeka, i-bead putty yeglasi kufuneka isetyenziswe ukugudisa i-gap kumphezulu we-insulation core block. I-Insulation core block layer ukunyanga kwaye emva koko uncamathisele 3 ~ 4 umaleko we-short-cut waziva, unokuncamathisela i-mold metal skeleton. Ncamathisela amathambo entsimbi, amathambo entsimbi afakwe kuqala ukuphelisa uxinzelelo lwe-welding, kunye namathambo entsimbi kunye nomsantsa ophakathi kokungunda kufuneka uzaliswe ukuthintelaFRPi-mold deformation kunye ne-skeleton yentsimbi.
Emva kokuba isiqwenga sokuqala sobumba siphilisiwe, isikhunta sisusiwe, i-edge endizayo ikhutshwe ngokugqithiseleyo, i-mold cavity ihlanjululwe kwi-debris, kwaye i-wax sheet isetyenziswe. Ubukhulu bephepha le-wax elisetyenzisiweyo kufuneka lifane kwaye ubude bube buncinci. Iphepha le-wax akufanele lifakwe kwiibhubhu zomoya, emva kokuba kukho iibhubhu zomoya, kufuneka zisuswe kwaye zifakwe kwakhona ukuze kuqinisekiswe ubungakanani bomgodi wokubumba. Amalungu e-Lap kufuneka anqunywe, kwaye izithuba phakathi kwamaphepha e-wax kufuneka zilinganiswe nge-putty okanye i-samente yerabha. Emva kokuba ishidi le-wax lisetyenzisiwe, i-mold yesibini inokuguqulwa ngendlela efanayo neyokuqala. Isikhunta sesibini siqhele ukwenziwa emva kokuba i-gelcoat itshizwe, kwaye imingxuma yokutofa kunye nemingxuma yokukhupha umoya kufuneka ilungiswe. Jika iqhekeza lesibini lokungunda, kufuneka uqale ususe i-edge ephaphazelayo, weld izikhonkwane zokumisa kunye neebholiti zokutshixa, ukuze unyangeke ngokupheleleyo emva kokudiliza.

I-3, Ukuhlolwa kwe-Mold kunye namanyathelo okulungisa
Emva kokudiliza kunye nokucoca, sebenzisa i-samente yerabha ukulinganisa ubukhulu bomgodi wokubumba. Ukuba ubukhulu kunye nobukhulu bunokuhlangabezana neemfuno, emva koko emva kokugaya kunye nenkqubo yokupholisa igqityiwe, i-RTM mold iya kuguqulwa ngempumelelo kwaye ingahanjiswa kwimveliso. Ukuba uvavanyo, ngenxa yolawulo olubi lwenkqubo kunye nezinye izizathu ezibangelwa yi-mold cavity ayihambelani neemfuno, i-scrap, iphinde ivule i-mold ibuhlungu kakhulu.
Ngokutsho kwamava, kukho iindlela ezimbini zokulungisa:
① ukrazule enye yokungunda, phinda uvule iqhekeza;
② Ukusetyenziswa kwenkqubo ye-RTM ngokwayo ukulungisa iimpawu zokungunda, ngokuqhelekileyo iqhekeza le-gelcoat yomphezulu we-gelcoat umaleko okhutshiweyo, obekwe phezuIfiber yeglasi eyomeleziweyo, elinye iqhekeza lokungunda lincanyatheliswe kwiphepha le-wax, i-gelcoat yokutshiza, kunye nenaliti yokubumba, ukuba iphiliswe emva kokulungiswa kwe-mold, ingahanjiswa ekusebenziseni.
