Inkqubo yokubumba yimali ethile yokulungiselela ukungena kwingxobo yesinyithi yesikhunta, ukusetyenziswa kweepress ezinomthombo wobushushu ukuvelisa ubushushu kunye noxinzelelo oluthile ukuze i-prepreg kwingxobo yesikhunta ithanjiswe bubushushu, ukuhamba koxinzelelo, igcwele ukuhamba, izaliswe yi-mold cavity mold kunye neemveliso zokuphilisa zendlela yenkqubo.
Iinkqubo yokubumbaIphawulwa yimfuno yokufudumeza kwinkqubo yokubumba, injongo yokufudumeza kukwenza i-prepreg resin softening flow, izele yi-mold cavity, kwaye ikhawulezise impendulo yokuphilisa yezinto ze-resin matrix. Ngexesha lenkqubo yokuzalisa i-mold cavity nge-prepreg, ayipheleli nje kwi-resin matrix, kodwa nakwizinto zokuqinisa, kunyei-resini-matrix kunye neefayibha zokuqinisa zizalisa zonke iindawo zomngxuma wesikhunta ngaxeshanye.
I-resin matrix viscosity kuphela inkulu kakhulu, kwaye i-bond inamandla ngokwaneleyo ukuba ihambe kunye neefayibha zokuqinisa, ngoko ke inkqubo yokubumba ifuna uxinzelelo olukhulu lokubumba. Oku kufuna ii-mold zesinyithi ezinamandla aphezulu, ukuchaneka okuphezulu, kunye nokumelana nokugqwala, kwaye kufuna ukusetyenziswa kwee-hot presses ezikhethekileyo ukulawula ubushushu be-molding yokuphilisa, uxinzelelo, ixesha lokubamba, kunye nezinye iiparameter zenkqubo.
Indlela yokubumba esebenza kakuhle kwimveliso, ukuchaneka kobungakanani bemveliso, kunye nokugqitywa komphezulu, ngakumbi kwisakhiwo esintsonkothileyo seemveliso zezinto ezidityanisiweyo ngokubanzi zinokubunjwa kube kanye, kwaye aziyi konakalisa ukusebenza kweemveliso zezinto ezidityanisiweyo. Ingxaki yayo ephambili kukuba uyilo lwe-mold kunye nokuveliswa kwayo kuyinkimbinkimbi ngakumbi, kwaye utyalo-mali lokuqala lukhulu. Nangona inkqubo yokubumba ineziphene ezingentla, i-moldinkqubo yokubumbaisenendima ebalulekileyo kwinkqubo yokubumba izinto ezidityanisiweyo.
1. Ukulungiselela
Yenza umsebenzi omhle wokulungiselela, ukubumba izixhobo zokubumba, kunye nomsebenzi wokuvavanya isithando somlilo, kwaye ucoce isikhunta ekusebenziseni okokugqibela i-resin eseleyo, kunye nenkunkuma, ukuze ugcine isikhunta sicocekile kwaye sigudile.
2. Ukusika nokubeka izinto ezilungiselelwe kwangaphambili
Kuya kwenziwa imveliso yezinto ezikrwada ze-carbon fiber, emva kokudlula uphononongo, ubale indawo yezinto ezikrwada, izinto, inani lamaphepha, umaleko wezinto ezikrwada ngomaleko wempepho edityanisiweyo, kwangaxeshanye kwi-superposition yezinto ezikrwada, zicinezelwe kwimo eqhelekileyo, umgangatho wenani elithile lezinto ezixineneyo.
3. Ukubumba nokunyanga
Beka izinto ezisetyenzisiweyo ezifakwe kwi-mold, kwaye kwangaxeshanye kwii-airbags zeplastiki zangaphakathi, vala i-mold, yonke ibe kumatshini wokubumba, ii-airbags zeplastiki zangaphakathi kunye noxinzelelo oluthile olungaguqukiyo, ubushushu obungaguqukiyo, misela ixesha elingaguqukiyo ukuze iphele.
4. Ukupholisa kunye nokunciphisa
Emva kwexesha elithile loxinzelelo ngaphandle kwesikhunta, qaphela ukuba umkhuhlane uqala kancinci, uze uvule isikhunta, ukhuphe ngaphandle kweso ukuze ucoce isikhunta sezixhobo.
5. Ukucubungula ukubunjwa
Emva kokuyisusa imveliso, kufuneka icocwe ngebrashi yentsimbi okanye ngebrashi yobhedu ukuze kukhuhlwe iplastiki eseleyo, kwaye ivuthelwe ngomoya ocinezelweyo, imveliso ebunjiweyo iyapholishwa, ukuze umphezulu ube bushelelezi kwaye ucoceke.
6. Uvavanyo olungonakalisiyo kunye novavanyo lokugqibela
Uvavanyo olungonakalisiyo kunye nokuhlolwa kokugqibela kweemveliso kwenziwa ngokweemfuno zamaxwebhu oyilo.
Ukususela ekuzalweni kukaii-composites ze-carbon fiber, esoloko ithintelwe ziindleko zokuvelisa kunye nokubetha kwemveliso, ayisetyenziswanga ngobuninzi. Isigqibo seendleko zokuvelisa i-carbon fiber kunye nokubetha yinkqubo yokubumba, inkqubo yokubumba izinto ze-carbon fiber composite kukho ezininzi, ezifana ne-RTM, i-VARI, itanki yokucinezela eshushu, i-oven curing prepreg (OOA), njl.njl., kodwa kukho iingxaki ezimbini: 1, ixesha lomjikelo wokubumba lide; 2, ixabiso libiza kakhulu (xa lithelekiswa nesinyithi kunye neplastiki). Inkqubo yokubumba i-Prepreg, njengohlobo lwenkqubo yokubumba, inokuphumeza imveliso yebhetshi kwaye inciphise iindleko zemveliso, ezisetyenziswa kakhulu nangakumbi.
