Iyiphi indlela yokubumba eyinhloko ye- epoxy ingilazi fibre ibhodi

1. Isendlalelo sokumanziswa kwezandla

Faka i-ejenti yokukhululwa kanye nongqimba lwe-resin ye-thermosetting ye-liquid esebenzayo ephakathi nendawo ene-viscosity ye-0.3-0.4PaS ebusweni besikhunta ngokushintshana (ngemuva kokuba ijazi lejeli lihlanganiswe) kanye nongqimba lwezinto eziqinisiwe ze-fiber. Izinto eziqiniswe ngomucu zinomuzwa ongaphezulu futhi ezingasontiwe zibe mahholo. Kunezinhlobo ezimbalwa ze-gauze (indwangu ye-checkered). Sebenzisa irola elibanjwa ngesandla noma ibhulashi ukuze umilise i-fiber reinforced material nge-resin, khipha amabhamuza omoya, futhi uhlanganise ungqimba oluyisisekelo. Ukusebenza kwe-layup kuphindaphindiwe izikhathi eziningi kuze kube yilapho kufinyelelwa ubukhulu bomklamo womkhiqizo. I-resin yelashwa ekamelweni lokushisa ngenxa yokusabela kwe-polymerization. Ingashiswa ukusheshisa ukuphulukiswa. Njengamanje, ukubeka izandla kuyindlela eyinhloko ezweni lami, okwenza cishe amaphesenti angama-80 wezinto ezihlanganisiwe ezisekelwe ku-resin.

2.Injini ye-Resin nokubumba kwe-resin RTM

I-RTM iyindlela yokubumba engaphansi kwengcindezi evaliwe. Beka izinto eziqiniswe i-fiber phakathi kwesikhunta esingenhla nesingezansi; vala isikhunta bese uqinisa isikhunta; faka i-resin ngaphansi kwengcindezi; vula isikhunta ngemuva kokuba i-resin isilaphekile, bese ususa umkhiqizo. Ngaphambi kokuba inqubo ye-resin gelation iqale, i-resin kufanele igcwaliswe emgodini wesikhunta, futhi ingcindezi inyusa i-resin ukuthi idlulisele ngokushesha kusikhunta futhi ikhulelise impahla ye-fiber.

3. Ukubunjwa kweshidi le-SMC (iBMC ngobuningi)

Faka iziqalisi, okokugcwalisa, okombala, izinto ezikhipha isikhunta zangaphakathi, izithasiselo ezishwaqa kancane, izingqimba, njll. ku-resin, futhi uzihlanganise ukuze wenze inhlaka yenhlaka. I-resin paste iwela efilimini engezansi yeyunithi ye-SMC (ifilimu ye-polyethylene evame ukusetshenziswa noma ifilimu yenayiloni), futhi ngasikhathi sinye, ihlala efilimu engezansi bese iqoshwa ibe yimicu yengilazi engu-25 ~ 55mm, bese imbozwa ngendwangu. ungqimba lwefilimu ukuze lube ishidi. I-sandwich roll. Gcina ikhoyili izinsuku ezimbalwa ukuze ujiye indwangu ukuze ifinyelele i-viscosity ebumbekayo. I-SMC inikezwa njengesipele esimweni esihlanganisiwe. Ikhoyili iyaqaqa, iyasikwa, ikalwe, ifakwe kuplatinamu yensimbi eshisayo, icindezelwe ukuze iqine futhi ibumbe, bese kutholwa umkhiqizo oqediwe.
