Ndeipi nzira huru yekuumba ye epoxy girazi fiber board
Ndeipi nzira huru yekuumba epoxy girazi fiber bhodhi
1. Ruoko-gadzika-nyoro kurara
Isa chigadziro chekusunungura uye chigadziko chepakati-chinoshanda chemvura thermosetting resin ine viscosity ye 0.3-0.4PaS kusvika pamusoro pemuumbi pamwe chete (mushure mokunge gel jasi rabatanidzwa) uye chidimbu che fiber yakasimbiswa zvinhu. Iyo fiber yakasimbiswa zvinhu ine pamusoro inonzwa uye isina-yakamonyoroka yakakora Kune akati wandei marudzi egauze (checkered jira). Shandisa roller inobatwa nemaoko kana bhurashi kupfekedza iyo fiber yakasimbiswa zvinhu neresin, dzinga mabhuru emhepo, uye kubatanidza base layer. Basa rekugadzirisa rinodzokororwa kakawanda kusvikira kukora kwekugadzirwa kwechigadzirwa kwasvika. Iyo resin inorapwa pakupisa kwekamuri nekuda kwepolymerization reaction. Inogona kupiswa kuti ikurumidze kupora. Parizvino, kuisa ruoko-up ndiyo fomu huru munyika yangu, iyo inoverengera 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 mainitiators, mafirita, pigment, mukati mold release agents, low-shrinkage additives, thickeners, etc. muresin, wosanganisa kuti uite resin paste. Iyo resin paste inowira pazasi firimu reiyo SMC unit (inowanzo shandiswa polyethylene firimu kana naironi firimu), uye panguva imwecheteyo, inogadzika pane yakaderera firimu uye yakachekwa kuita 25 ~ 55mm girazi fiber tambo, uye yobva yafukidzwa ne layer yefirimu kuita pepa. Sandwich roll. Chengetedza coil kwemazuva akati wandei kuti uwedzere zvinhu kuti zvisvike pakuumbwa kwe viscosity. SMC inopihwa se backup mu bundled state. Iyo coil inovhurwa, inochekwa, inoyerwa, inoiswa mune inopisa simbi mold platinamu, inomanikidzwa kusimba uye kuumbwa, uye ipapo chigadzirwa chakapedzwa chinowanikwa.
