Yeyiphi indlela yokubumba ephambili ibhodi yefayibha yeglasi epoxy

1. Isandla sokubeka-ukumanzi okumanzi

Faka isicelo se-agent agent kunye noluhlu lwe-medium-active liquid thermosetting resin kunye ne-viscosity ye-0.3-0.4PaS ukuya kumphezulu we-mold ngokulandelelana (emva kokuba i-gel coat coagulated) kunye noluhlu lwezinto eziqinisiweyo zefiber. Ifiber eyomeleziweyo imathiriyeli ivakala kwaye irhabaxa engajijwanga Kukho iindidi ezininzi zegauze (ilaphu letshekhi). Sebenzisa i-roller ephathwayo ngesandla okanye ibrashi ukumilisela imathiriyeli eyomeleziweyo yefiber nge-resin, khupha amaqamza omoya, kwaye udibanise umaleko wesiseko. Umsebenzi we-layup uphindwe kaninzi de kube ubukhulu boyilo lwemveliso bufikelelwe. I-resin iphiliswa kwindawo yokushisa ngenxa ye-polymerization reaction. Inokufudunyezwa ukukhawulezisa ukunyanga. Okwangoku, ukubekwa kwezandla yeyona ndlela iphambili kwilizwe lam, elibalelwa malunga ne-80% yezinto ezixutywe ne-resin-based composite.

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, iifayili, ii-pigments, ii-agent zangaphakathi zokukhupha i-mold, i-low-shrinkage additives, i-thickeners, njl njl kwi-resin, kwaye udibanise ukwenza i-resin paste. Intlama ye-resin iwela kwifilimu esezantsi yeyunithi ye-SMC (idla ngokusetyenziswa ifilimu ye-polyethylene okanye ifilimu yenayiloni), kwaye kwangaxeshanye, ihlala kwifilimu esezantsi kwaye inqunyulwe ibe yi-25 ~ 55mm imisonto yeglasi yefiber, kwaye emva koko igqunywe ngentsimbi. umaleko wefilimu ukuze ube liphepha. I-sandwich roll. Gcina ikhoyili iintsuku eziliqela ukuze ujiye izinto ukuze ufikelele kwi-viscosity enokubumba. I-SMC ibonelelwa njengenkxaso kwimo edityanisiweyo. I-coil ivuliwe, inqunywe, ilinganiswe, ifakwe kwi-platinamu yensimbi evuthayo, ixinzelelwe ukuba iqiniswe kwaye ibumbe, kwaye ke imveliso egqityiweyo ifunyenwe.
