Inqubo yokubumba inani elithile lokulungiselela ukungena emgodini wesikhunta sensimbi, ukusetshenziswa kwemishini yokucindezela enomthombo wokushisa ukukhiqiza izinga lokushisa elithile kanye nengcindezi ukuze i-prepreg emgodini wesikhunta ithanjiswe ukushisa, ukugeleza kwengcindezi, ukugeleza okugcwele, okugcwele ukubumba kwesikhunta kanye nemikhiqizo yokwelapha yendlela yenqubo.
Iinqubo yokubumbaIbonakala ngesidingo sokushisa enkambisweni yokubumba, inhloso yokushisa ukwenza ukugeleza kokuthambisa kwe-prepreg resin, kugcwele umgodi wesikhunta, futhi kusheshiswe ukusabela kokwelapha kwezinto ze-resin matrix. Ngesikhathi senqubo yokugcwalisa umgodi wesikhunta nge-prepreg, akugcini nje ngokugeleza kwe-resin matrix, kodwa futhi nezinto zokuqinisa, kanyei-resinimicu ye-matrix kanye ne-reinforcement igcwalisa zonke izingxenye zesikhala sesikhunta ngasikhathi sinye.
I-resin matrix viscosity kuphela enkulu kakhulu, futhi isibopho siqine ngokwanele ukugeleza nemicu yokuqinisa, ngakho-ke inqubo yokubumba idinga ingcindezi enkulu yokubumba. Lokhu kudinga isikhunta sensimbi esinamandla aphezulu, ukunemba okuphezulu, kanye nokumelana nokugqwala, futhi kudinga ukusetshenziswa kwemishini ekhethekile yokucindezela ukushisa ukulawula izinga lokushisa lokubumba, ingcindezi, isikhathi sokubamba, kanye neminye imingcele yenqubo.
Indlela yokubumba esebenza kahle kakhulu ekukhiqizeni, ukunemba kosayizi womkhiqizo, kanye nokuqedwa kobuso, ikakhulukazi isakhiwo esiyinkimbinkimbi semikhiqizo yezinto ezihlanganisiwe ngokuvamile ingabunjwa kanye, futhi ngeke ilimaze ukusebenza kwemikhiqizo yezinto ezihlanganisiwe. Iphutha layo eliyinhloko ukuthi ukwakheka kwesikhunta kanye nokukhiqizwa kuyinkimbinkimbi kakhulu, futhi ukutshalwa kwezimali kokuqala kukhulu. Nakuba inqubo yokubumba inamaphutha angenhla, isikhuntainqubo yokubumbaisasesikhundleni esibalulekile enqubweni yokubumba izinto ezihlanganisiwe.
1. Ukulungiselela
Yenza umsebenzi omuhle wokulungiselela, ukubumba amathuluzi okubumba, ngocezu lomsebenzi wokuhlola isithando, bese uhlanza isikhunta ekusebenziseni okokugcina i-resin esele, kanye nodoti, ukuze ugcine isikhunta sihlanzekile futhi sibushelelezi.
2. Ukusika nokubeka ama-prepreg
Kuzokwenziwa umkhiqizo wezinto zokusetshenziswa ze-carbon fiber ezilungele, zilungiswe ngemuva kokudlula isibuyekezo, zibale indawo yezinto zokusetshenziswa, izinto zokwakha, inani lamashidi, ungqimba lwezinto zokusetshenziswa ngengqimba yempepho ehlanganisiwe, ngesikhathi esifanayo endaweni yokufakwa kwezinto zokusetshenziswa kwengcindezi yangaphambi kokucindezela, ecindezelwe ngesimo se-regular, ikhwalithi yenani elithile lezinto ezixineneyo.
3. Ukubumba nokulungisa
Faka izinto zokusetshenziswa ezihlanganisiwe esikhumbeni, futhi ngesikhathi esifanayo ezikhwameni zomoya zangaphakathi zepulasitiki, vala isikhunta, sonke emshinini wokubumba, amakhwameni omoya angaphakathi epulasitiki kanye nokucindezela okuthile okungaguquki, izinga lokushisa elingaguquki, setha isikhathi esingaguquki ukuze siqine.
4. Ukupholisa nokususa ukungcola
Ngemva kwesikhathi sokucindezela ngaphandle kwesikhunta, qala uqonde ukuthi umkhuhlane ungakanani isikhathi esithile, bese uvula isikhunta, ukhiphe ngaphandle kweso ukuze uhlanze isikhunta samathuluzi.
5. Ukucubungula ukubumba
Ngemva kokususa umkhiqizo, umkhiqizo udinga ukuhlanzwa, ngebhulashi lensimbi noma ibhulashi lethusi ukuze kukhuhlwe ipulasitiki esele, bese uvuthelwa ngomoya ocindezelwe, umkhiqizo obunjiwe uyapholishwa, ukuze indawo ibushelelezi futhi ihlanzeke.
6. Ukuhlolwa okungabhubhisi kanye nokuhlolwa kokugcina
Ukuhlolwa okungonakalisi kanye nokuhlolwa kokugcina kwemikhiqizo kwenziwa ngokwezidingo zemibhalo yokuklama.
Kusukela ekuzalweni kukaizinhlanganisela ze-carbon fiber, ehlala inqunyelwe yizindleko zokukhiqiza kanye nokushaya kokukhiqiza, ayizange isetshenziswe ngobuningi obukhulu. Isinqumo sezindleko zokukhiqiza i-carbon fiber kanye nokushaya yinqubo yokubumba, inqubo yokubumba izinto ezihlanganisiwe ze-carbon fiber kuneziningi, njenge-RTM, i-VARI, ithangi lokucindezela elishisayo, i-oven curing prepreg (OOA), njll., kodwa kunezinkinga ezimbili: 1, isikhathi somjikelezo wokubumba side; 2, intengo iyabiza (uma kuqhathaniswa nensimbi nepulasitiki). Inqubo yokubumba i-Prepreg, njengohlobo lwenqubo yokubumba, ingafeza ukukhiqizwa kweqembu futhi inciphise izindleko zokukhiqiza, okusetshenziswa kabanzi kakhulu.
