Yeyiphi indlela yokubumba ephambili yebhodi ye-mica yebhodi yeglasi ye-epoxy
Yeyiphi indlela yokubumba ephambili ibhodi mica ibhodi yefayibha yeglasi epoxy
1. Isandla sokubeka-ukumanzi okumanzi
Faka isicelo searhente yokukhutshwa kunye nolwahlulo lwangaphakathi lwento esebenzayo ye-resin ye-thermosetting ene-viscosity ye-0.3-0.4PaS kumphezulu wesikhunta (emva kokuba idyasi ye-gel idityanisiwe) kunye nophahla lwezixhobo eziqinisiweyo. Izinto eziqinisiweyo zefayibha zibonakala ngaphezulu kwaye zingajijekanga zirhabaxa Kukho iintlobo ezininzi zegeyisi (ilaphu elihlolwe). Sebenzisa irola ebanjwa ngesandla okanye ibrashi ukumitha i-resin ngesixhobo esomeleleyo sefayibha, ukhuphe amaqamza omoya, kunye nokudibanisa umaleko wesiseko. Imisebenzi yokubeka iphindaphindwe amaxesha amaninzi de kube ubukhulu bokuyilwa kwemveliso bufikelelwe. I-resin iyaphiliswa kwiqondo lokushisa kwegumbi ngenxa yokuphendula kwe-polymerization. Unokufudunyezwa ukukhawulezisa ukunyanga. Okwangoku, ukubekwa ngesandla yeyona nto iphambili e-China, enika ingxelo malunga ne-80% yezinto zokwenziwa kwentlaka.
2. Inaliti yentlaka kunye nokudluliselwa kweretti yokubumba iRTM
I-RTM yindlela evaliweyo yokubumba evaliweyo yoxinzelelo olusezantsi. Beka izinto eziqinisiweyo zefayibha phakathi komngundo ongaphezulu kunye nowezantsi; vala ukungunda kunye nokubamba ukungunda; jofa i-resin phantsi koxinzelelo; vula ukungunda emva kokuphiliswa kwentlaka, kwaye ususe imveliso. Phambi kokuba inkqubo ye-resin gelation iqale, i-resin kufuneka igcwaliswe kumngxunya wokungunda, kwaye uxinzelelo lwenza ukuba i-resin ikhawuleze idlulisele kumbumba kwaye ikhawuleze izinto zefayibha.
3. Ukubumba iphepha le-SMC (ubuninzi be-BMC)
Yongeza abaqalisi, iifillers, i-pigment, ii-agent zangaphakathi zokukhutshwa kwe-mold, izongezo eziphantsi ze-shrinkage, i-thickeners, njl njl. I-resin paste iwela kwifilimu esezantsi yeyunithi ye-SMC (esetyenziswa rhoqo kwifilimu ye-polyethylene okanye kwifilimu ye-nylon), kwaye kwangaxeshanye, ihlala kwifilimu esezantsi kwaye isikwe ibe yimicu yeglasi eyi-25-55mm, emva koko igutyungelwe Uluhlu lwefilimu ukuze lube lishiti. Isandwich roll. Gcina iikhoyili kangangeentsuku ezininzi ukomeleza umbandela ukuze ufikelele kwi-viscosity ebunjiweyo. I-SMC ibonelelwa njenge-backup kwimeko e-bundled. Ikhoyili ayityhilwanga, iyasikwa, iyalinganiswa, ifakwe kwiplatinam yentsimbi eshushu, icinezelwe ukuqinisa nokubumba, emva koko imveliso egqityiweyo ifunyenwe.
