iindaba

Inkqubo ye-RTM ineengenelo zokuba ayisebenzisi kakhulu, ayisebenzisi kakhulu, ayisebenzisi kakhulu i-styrene, ayisebenzisi ngokuchanekileyo kwaye ayisebenzisi gwenxa, ayinakuguquguquka kakhulu, inokuba semgangathweni ophezulu womphezulu ukuya kuthi ga kwizinga A.
Inkqubo yokubumba i-RTM ifuna ubungakanani obuchanekileyo ngakumbi besikhunta. I-rtm isebenzisa i-yin kunye ne-yang ukuvala isikhunta, ngoko ke impazamo yobukhulu besikhunta kunye nolawulo oluchanekileyo lobukhulu bomngxuma emva kokuvala isikhunta yingxaki ephambili.

1, Ukukhetha izinto
Ukulawula ukuchaneka kwesikhunta, ukukhethwa kwezinto ezikrwada yinto ebalulekileyo. UkuveliswaUmngundo we-RTMI-gel coat esetyenziswa kwi-mold coat kufuneka ibe nobunzima obuphezulu, ukumelana nobushushu obuphezulu kunye nokuncipha okuphantsi, ngokubanzi ingasetyenziswa kwi-vinyl ester mold gel coat.
I-RTM mold resin ngokubanzi ikwafuna ukumelana nobushushu kunye nokuqina okuhle, inqanaba elithile lokuqina kwempembelelo, ukuncitshiswa kuncinci okanye kufutshane nokuncipha kwe-zero. Ii-RTM molds ezinezixhobo zokuqinisa ifayibha zingasetyenziswa i-30g / ㎡ non-alkali surface felt kunye ne-300g / ㎡ non-alkali short-cut felt. Nge-300g / m non-alkali short-cut felt kune-450g / m non-alkali short-cut felt eyenziwe nge-mold shrinkage iphantsi, ichaneke kakhulu.

2, Ulawulo lwenkqubo
Ukukhethwa kwezinto ezikrwada kukulawula ubungakanani be-RTM mold kunye nobukhulu bomngxuma wekhonkco elibalulekileyo, kwaye kwinkqubo yokujika umngxuma nangaliphi na ixesha ulawulo lomgangatho luyinkqubo ebaluleke ngakumbi. Ukuba olu lawulo lwenkqubo alufanelekanga, nokuba izinto ezikrwada ziyahlangabezana neemfuno, kunzima ukujika umngxuma ngobungakanani obuchanekileyo kunye nobukhulu bomngxuma obufanelekileyo.
Inkqubo yokujika isikhunta kufuneka iqale iqonde ukuchaneka kwesikhunta somthi esiguqukayo. Ukuze kuqinisekiswe ukuchaneka, ekuqaleni kwesihluzo, uyilo lwesikhunta somthi lungasetyenziswa ngokwezinga lokuncipha kwesikhunta ukuze kushiyeke inani elithile lesibonelelo sokuncipha. Ukongeza, kufuneka kunikwe ingqalelo ekutshintsheni komphezulu womthi olungisa isikhunta, kufuneka kugrunjwe amanxeba omphezulu womthi. Amanxeba kunye nokuncipha kwenkuni okungaguqukiyo kuya kubangela ukuba umphezulu womthi oguquliweyo we-fiberglass ungabi tyaba. Grumba amanxeba kwaye ususe amaqhekeza omphezulu, umphezulu womthi oguquliweyo kufuneka ukrwelwe unyango lwe-putty, ngokubanzi kufuneka ukrwelwe amaxesha ama-2 ukuya kwama-3. Emva kokuba i-putty inyangiwe, sebenzisa iphepha lesanti ukupolisha umphezulu ude uhlangabezane ngokupheleleyo neemfuno zobungakanani kunye nokuchaneka kwesimo.
Ukuveliswa kwesikhunta somthi kufuneka kukulungele ukuchitha umgudu, kuba ngokubanzi, ukuchaneka kobukhuluIsikhunta se-FRP ekugqibeleniKuxhomekeke ekuchanekeni kwesikhunta somthi. Ukuze kuqinisekiswe ukuba umphezulu wesikhunta seplastiki esiqinisiweyo sefayibha yeglasi uthambile kwaye ucocekile, jika isiqwenga sokuqala sesikhunta seplastiki esiqinisiweyo sefayibha yeglasi, umaleko wejazi lejeli usebenzisa indlela yokutshiza ufanelekile ngakumbi.
I-gelcoat yokutshiza kufuneka iqwalasele ukulungisa ukuhamba komoya kwesibhamu, ukuze i-gelcoat resin atomization ifane, ingabonakalisi amasuntswana. I-spray gun kunye ne-gun mazibe ngaphandle kwe-mold, ukuze zingabangeli ukuba i-gel coat yasekuhlaleni ixhonywe, nto leyo echaphazela umgangatho womphezulu. Emva kokuba umaleko we-gel coat ulungisiwe, ncamathisela i-surface felt. I-surface felt mayibe ngaphandle kwe-mold, ukuze ingabangela ukuba i-gelcoat yasekuhlaleni ixhonywe, nto leyo echaphazela umgangatho womphezulu.
Emva kokuba umaleko wejazi lejeli ulungisiwe, ncamathisela umphezulu wejazi, umphezulu wejazi kufuneka ugutyungelwe ngeflethi ethe tyaba, egobileyo okanye ethe tyaba kufuneka isikwe kwaye inqunyulwe. Namathisela umphezulu wejazi olungileyo, ibrashi ingacwiliswa kwinani elincinci le-resin ukuze ingene kwi-felt yomphezulu, qwalasela ulawulo lobungakanani beglu, zombini ukuze zikwazi ukungena ngokupheleleyo kwifayibha, kodwa kungabi kakhulu. Umxholo weglue ophezulu, i-bubble ayilula ukuyikhupha, kwaye ibangela ukuncitshiswa okukhulu, okukhulu. Umaleko wejazi lomphezulu wejeli ucima i-resin ukuze ithathe amaqamza, amaqamza e-pick awakwazi ukusika umaleko wejazi lejeli.
Emva kokukhetha amaqamza, ukucola kakuhle, ukususa ii-fiberglass burrs kunye nokususa uthuli oludadayo, uncamathisele ngesandla i-300g / m² i-felt emfutshane engeyiyo i-alkali, ixesha ngalinye kufuneka uncamathisele i-1 ~ 2 layers ye-paste, ukuze inyangeke emva kwencopho ye-exothermic ngaphambi kokuba uqhubeke nokuncamathisela. Ncamathisela kubukhulu obufunekayo, ungabeka umbhobho wobhedu, kwaye ubeke i-insulation core block. Ukuguqulwa kwee-glass beads i-resin putty, njengokubekwa kwe-thermal insulation core block adhesive, apho kuza kugcwalisa khona umsantsa phakathi kwe-thermal insulation core block.
Emva kokubeka, i-glass bead putty kufuneka isetyenziswe ukuthambisa umsantsa kumphezulu we-insulation core block. Ukulungisa umaleko we-insulation core block uze uncamathisele iileya ezi-3 ukuya kwezi-4 ze-short-cut felt, ungancamathisela i-mold steel skeleton. Uncamathisele i-steel skeleton, i-steel skeleton iqale i-anneal ukuze kupheliswe uxinzelelo lwe-welding, kwaye i-steel skeleton kunye nomsantsa phakathi kwe-mold kufuneka zizaliswe ukuthintelaI-FRPukuguqulwa kwesikhunta ngethambo lentsimbi.
Emva kokuba iqhekeza lokuqala lesikhunta lilungisiwe, isikhunta siyasuswa, umphetho ongaphezulu obhabhayo uyasuswa, umngxuma wesikhunta uyacocwa kwimfucumfucu, kwaye ishidi lekhunta liyasetyenziswa. Ubukhulu beshidi lekhunta elisetyenzisiweyo kufuneka bufane kwaye ubude bube buncinci. Ishidi lekhunta akufuneki lisongelwe ngamaqamza omoya, xa sele kukho amaqamza omoya, kufuneka lisuswe kwaye linamathiselwe kwakhona ukuqinisekisa ubungakanani bomngxuma wesikhunta. Amalungu eentambo kufuneka asikwe, kwaye izithuba phakathi kwamaphepha ekhunta kufuneka zilinganiswe nge-putty okanye isamente yerabha. Emva kokuba ishidi lekhunta lisetyenzisiwe, isikhunta sesibini sinokujikwa ngendlela efanayo nesikhunta sokuqala. Isikhunta sesibini sidla ngokwenziwa emva kokuba i-gelcoat itshiziwe, kwaye kufuneka kulungiswe imingxunya yenaliti kunye nemingxunya yokukhupha umoya. Jika iqhekeza lesibini lesikhunta, kufuneka uqale ususe umphetho obhabhayo, udibanise iiphini zokubeka kunye neebholiti zokutshixa, ukuze uphiliswe ngokupheleleyo emva kokudilizwa.

3, Ukuhlolwa kwesikhunta kunye namanyathelo okulungisa
Emva kokucoca nokususa inkunkuma, sebenzisa isamente yerabha ukulinganisa ubukhulu bomngxuma wesikhunta. Ukuba ubukhulu kunye nobukhulu bunokuhlangabezana neemfuno, emva kokuba inkqubo yokugaya nokupolisha igqityiwe, umngxuma we-RTM uya kujika ngempumelelo kwaye ungathunyelwa kwimveliso. Ukuba uvavanyo, ngenxa yokulawulwa kakubi kwenkqubo kunye nezinye izizathu ezibangelwa ngumngxuma wesikhunta aluhlangabezani neemfuno, inkunkuma, ukuvula kwakhona umngxuma kuyinto embi kakhulu.
Ngokwamava kukho iindlela ezimbini zokulungisa ezinokubangela iingxaki:
1. Ndayisusa enye yesikhunta, ndayivula kwakhona;
② Ukusetyenziswa kwenkqubo ye-RTM ngokwayo ukulungisa iimpawu zesikhunta, ngokuqhelekileyo isiqwenga somphezulu wesikhunta sinqunyulwe, sibekwe phezu kwaso.izinto eziqinisiweyo zefayibha yeglasi, esinye isiqwenga sesikhunta sincamatheliswa kwiphepha le-wax, i-spray gelcoat, kwaye emva koko i-mold injection, eza kunyangwa emva kokulungiswa kwesikhunta, ingathunyelwa ukuze isetyenziswe.
