Iyiphi indlela yokubumba eyinhloko ye- ibhodi le-mica epoxy ingilazi fibre ibhodi

1. Isendlalelo sokumanziswa kwezandla

Faka isicelo se-ejenti yokukhipha kanye nongqimba lwe-resin ye-liquid esebenzayo ye-liquid nge-viscosity ye-0.3-0.4PaS ebusweni besikhunta ngokulandelana (ngemuva kokuthi ijazi le-gel lijiyile) kanye nongqimba lwezinto eziqinisiwe ze-fiber. Izinsimbi eziqinisiwe ze-fiber zinobuso obuzwakalayo futhi obungasontekile kunezinhlobo eziningana ze-gauze (indwangu ye-checkered). Sebenzisa i-roller ebanjwa ngesandla noma ibhulashi ukukhulelisa i-resin ngezinto eziqinisiwe ze-fiber, ukhiphe amabhamuza womoya, bese uhlanganisa ungqimba lwesisekelo. Ukusebenza kokubeka kuphindaphindwa kaningi kuze kufinyelelwe ukushuba komkhiqizo. I-resin yelashwa ekamelweni lokushisa ngenxa yokusabela kwe-polymerization. Kungashiswa ukusheshisa ukwelashwa. Njengamanje, ukubeka ngesandla kuyindlela eyinhloko eChina, ebala cishe ama-80% wezinto ezihlanganisiwe ezakhiwe ngenhlaka.

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, ukugcwalisa, izingulube, izinto zokukhipha isikhunta sangaphakathi, izithasiselo zokuncipha okuphansi, ama-thickeners, njll. Ku-resin, bese uwaxuba ukwakha unamathisela i-resin. Okunamathiselwe kwe-resin kuwela kwifilimu engezansi yeyunithi ye-SMC (ifilimu ye-polyethylene esetshenziswa kakhulu noma ifilimu yenayiloni), futhi ngasikhathi sinye, ihlala kwifilimu engezansi bese igawulwa ibe yimicu engu-25-55mm yengilazi yefayibha, bese imbozwa ungqimba lwefilimu ukuze lube ishidi. Isandwich roll. Gcina ikhoyili izinsuku ezimbalwa ukushuba le nto ukuze ufinyelele ku-viscosity ebumbekayo. I-SMC inikezwa njengesipele esimweni esihlanganisiwe. Ikhoyili ayivulwa, iyasikwa, iyalinganiswa, ifakwe ku-platinum yensimbi evuthayo, icindezelwe ukuqinisa nokubumba, bese kutholakala umkhiqizo ophelile.
