Ndeipi nzira huru yekuumba mica bhodhi epoxy girazi fiber bhodhi
1. Ruoko-gadzika-nyoro kurara
Isa chinoburitsa mumiririri uye nhepfenyuro yepakati-inoshanda mvura thermosetting resin ine viscosity ye 0.3-0.4PaS kune iyo pamusoro peforoma zvakare (mushure mejasi rejasi zvasunganidzwa) uye nhete yezvinhu zvakasimbiswa nefibre. Iyo faibha yakasimbiswa zvinhu zvine pamusoro pekunzwa uye zvisina-kumonyoroka zvakasindimara Kune akatiwandei marudzi e gauze (cheki yakarukwa). Shandisa ruoko rwakabata roller kana bhurasho kuisa iyo resini neiyo fiber yakasimbiswa zvinhu, kudzinga mweya mabhuru, uye kumisikidza iwo wepasi dura. Kuisa mashandiro kunodzokororwa kakawanda kudzamara dhizaini yechigadzirwa yasvika. Iyo resin inorapwa pane tembiricha yemukati nekuda kwekupora kwemaitiro. Inogona kudziirwa kuti ikurumidze kurapwa. Parizvino, kuisa ruoko-kumusoro ndiyo fomu huru muChina, iyo inosvika makumi masere muzana ezve resin-based composite zvinhu.
2. Resin jekiseni uye nebwe kuchinjisa RTM kuumbwa
RTM yakavharika-chakuvhe yakaderera-kumanikidza nzira yekuumba. Isa iyo fiber-yakasimbiswa zvinhu pakati peiyo yepamusoro uye yakaderera mafomu; vhara muforoma uye sunga muforoma; baya jekiseni pasi pesimba; vhura chakuvhuvhu mushure mekurapwa nebwe, uye bvisa chigadzirwa. Iyo resin gelation isati yatanga maitiro, iro resini rinofanira kuzadzwa muforoma mhango, uye kumanikidza kunoitisa iro resini kuti ikurumidze kuendesa muchimiro uye kupinza iyo fiber zvinhu.
3. Kuumba kwesheet SMC (BMC yakawanda)
Wedzera vatangi, mafiringi, pigments, zvemukati muforoma kuburitsa vamiririri, yakaderera shrinkage zvinowedzera, thickeners, nezvimwewo mukati mebhegi, wozvisanganisa kuti vagadzire resin paste. Iyo resin paste inowira pane yepazasi firimu reSMC unit (inowanzo shandiswa polyethylene firimu kana nylon firimu), uye panguva imwecheteyo, inogadzikana pane yepazasi firimu ndokutemwa kuita 25-55mm girazi fiber tambo, uyezve yakafukidzwa ne rukoko rwefirimu kuti rive jira. Sandwich mupumburu. Chengetera coil kwemazuva akati wandei kuti ubaye zvinhu zvacho kuti usvike viscosity inoumbika. SMC inopihwa sekuchengetedza mune yakasungwa nyika. Iyo coil haina kuvhurwa, kutemwa, kuyerwa, kuiswa mukati inopisa simbi muforoma platinamu, yakamanikidzwa kusimbisa uye kuumba, uye ipapo chigadzirwa chakapedzwa chinowanikwa.
