Mokhoa o ka sehloohong oa ho bopa oa boto ea epoxy fiber

1. Ho robala ka matsoho ho kolobisa

Sebelisa moemeli oa ho lokolla le lesela la metsi a mahareng a sebetsang a thermosetting resin e nang le viscosity ea 0.3-0.4PaS holim’a hlobo ka lehlakoreng le leng (ka mor’a hore seaparo sa gel se kopane) le lera la lisebelisoa tse matlafalitsoeng tsa fiber. Lisebelisoa tse matlafalitsoeng ka fiber li na le maikutlo a holimo le a sa sothehileng Ho na le mefuta e mengata ea gauze (lesela la checkered). Sebelisa rolara e tšoaroang ka letsoho kapa borashe ho kenya fiber e matlafalitsoeng ka resin, leleka lipululana tsa moea, ‘me le hate boalo ba motheo. Ts’ebetso ea layup e phetoa ka makhetlo a mangata ho fihlela botenya ba moralo oa sehlahisoa bo fihla. Resin e phekoloa ka mocheso oa kamore ka lebaka la karabelo ea polymerization. E ka futhumatsa ho potlakisa pholiso. Hona joale, ho beha matsoho ke mokhoa o ka sehloohong naheng ea heso, e leng karolo ea 80% ea lisebelisoa tse entsoeng ka resin.

2. Resin ente le ho fetisoa ha RTM molding

RTM ke mokhoa o koetsoeng oa mofuta o tlase oa khatello e tlase. Beha thepa e matlafalitsoeng ka fiber pakeng tsa hlobo e ka holimo le e tlaase; koala hlobo ‘me u kokobele hlobo; kenya resin tlas’a khatello; bula hlobo ka mor’a hore resin e phekoloe, ‘me u tlose sehlahisoa. Pele ts’ebetso ea “resin gelation” e qala, resin e tlameha ho tlatsoa ka mokoting oa hlobo, ‘me khatello e etsa hore resin e fetisetsoe ka har’a hlobo ka potlako ebe e kenya thepa ea fiber.

3. Ho thehoa ha lakane SMC (boholo BMC)

Kenya li-initiators, li-filler, li-pigments, li-agents tsa ka hare tsa ho lokolla hlobo, li-additives tse fokolang haholo, li-thickeners, joalo-joalo ka har’a resin, ‘me u li kopanye ho etsa setlolo sa resin. Sekhahla sa resin se oela filiming e ka tlase ea yuniti ea SMC (filimi e sebelisoang hangata ea polyethylene kapa filimi ea nylon), ‘me ka nako e ts’oanang, e lula filiming e ka tlase ebe e khangoa ka likhoele tsa fiber ea khalase ea 25 ~ 55mm, ebe e koaheloa ka lesela. lera la filimi ho fetoha letlapa. Moqolo oa sandwich. Boloka khoele ka matsatsi a ‘maloa ho tiisa lisebelisoa ho fihlela viscosity e ka bōptjoang. SMC e fanoa e le bekapo maemong a mangata. Coil e phutholoha, e khaola, e lekantsoe, e kenngoa ka har’a platinamo ea tšepe e futhumetseng, e hatelloa ho tiisa le ho bōptjoa, ebe sehlahisoa se felile se fumanoa.
