1. Hand Lay-up Molding

Kuumbwa kwemaoko ndiyo nzira yechinyakare yekugadzira fiberglass-reinforced plastic (FRP) flanges. Iyi nzira inosanganisira nemaoko kuisa resin-impregnatedfiberglass jirakana kuti mameti muforoma uye kuvabvumira kurapa. Iyo chaiyo maitiro ndeaya anotevera: Chekutanga, resin-yakapfuma yemukati liner layer inogadzirwa uchishandisa resin uye fiberglass jira. Mushure mokunge liner layer inoporesa, inobviswa kubva muhutu, uye chidimbu chekugadzirisa chinovakwa. Resin inozokweshwa pane zvese zviri zviviri mold pamusoro uye yemukati liner. Pre-akachekwa fiberglass machira machira akaiswa zvinoenderana neyakafanotemerwa stacking hurongwa, neimwe layer yakaumbwa uchishandisa roller kuti ive nechokwadi chekupinda mukati. Kamwe ukobvu hunodiwa hunowanikwa, gungano rinorapwa uye rinoderedzwa.

Iyo matrix resin yekuumbwa kwemaoko-kuumbwa kazhinji inoshandisa epoxy kana unsaturated polyester, nepo iyo yekusimbisa iri yepakati-alkali kana.alkali-isina fiberglass jira.

Zvakanakira: Zvinodiwa zvemidziyo yakaderera, kugona kugadzira zvisiri-standard flanges, uye hapana zvinorambidzwa paflange geometry.

Kukanganisa: Mabhuru emhepo akaumbwa panguva yekurapa resin anogona kutungamirira kune porosity, kuderedza simba remagetsi; kugadzirwa kwakaderera; uye isina kuenzana, isina kucheneswa kupera kwepamusoro.

2. Compression Molding

Kuomesa kuumbwa kunosanganisira kuisa huwandu hwakayerwa hwezvinhu zvekuumba kuita flange mold uye kuchirapa pasi pekumanikidzwa uchishandisa muchina. Zvinhu zvekuumba zvinosiyana uye zvinogona kusanganisira pre-yakasanganiswa kana pre-impregnated short-cut fiber compounds, recycled fiberglass cloth scraps, resin-impregnated multi-layer fiberglass cloth rings/strips, stacked SMC (sheet molding compound) masheets, kana preforms prewoven fiberglass fabric preforms. Munzira iyi, flange disk nemutsipa zvinoumbwa panguva imwe chete, kusimbisa simba rekubatana uye kutendeseka kwemaitiro.

Zvakanakira: Yakakwira dimensional kurongeka, kudzokororwa, kukodzera kweotomatiki kugadzirwa kwakawanda, kugona kuumba yakaoma tapered-mitsipa flanges mune imwe nhanho, uye aesthetically yakatsetseka nzvimbo inoda kusagadziriswa.

Zvakaipa: Kudhura kukuru kweforoma uye zvisingakwanisi pakukura kweflange nekuda kwekumanikidza kwemubhedha.

3. Resin Transfer Molding (RTM)  

RTM inosanganisira kuisa fiberglass reinforcement mune yakavharwa mold, jekiseni resin kuisa nhumbu, uye kurapa. Iyo nzira inosanganisira:

• Kuisa fiberglass preform inoenderana neflange geometry mugomba rekuumbwa.
• Jekiseni yakaderera-viscosity resin pasi pekudzora tembiricha uye kumanikidza kugutsa preform uye kudzinga mweya.
• Kupisa kurapa uye kudhiza iyo yakapedzwa flange.

Resins anowanzo unsaturated polyester kana epoxy, nepo kusimbiswa kunosanganisirafiberglass inopfuurira matskana machira akarukwa. Mafirita senge calcium carbonate, mica, kana aluminium hydroxide anogona kuwedzerwa kuwedzera zvivakwa kana kuderedza mitengo.

Zvakanakira: Nzvimbo dzakapfava, kugadzirwa kwepamusoro, kuvharika-mold kushanda (kuderedza kuburitswa uye njodzi dzehutano), inotungamira fiber kurongeka kwesimba rakagadziridzwa, yakaderera capital investment, uye kuderedzwa kwekushandisa / simba.

4. Vacuum-Assisted Resin Transfer Molding (VARTM)

VARTM inogadzirisa RTM nekubaya resin pasi pevacuum. Maitiro aya anosanganisira kusunga fiberglass preform pane yechirume mold ine vacuum bhegi, kubudisa mweya kubva mugomba reforoma, uye kudhirowa resin mu preform kuburikidza ne vacuum pressure.

Kuenzaniswa neRTM, VARTM inogadzira flanges ine yakaderera porosity, yakakwirira fiber content, uye yakakwirira mechanical simba.

5. Airbag-yakabatsira resin transfer molding

Airbag-inobatsira RTM kuumba zvakare imhando yekuumba tekinoroji yakagadziridzwa pahwaro hweRTM. Maitiro ekugadzira maflange nenzira iyi yekuumba ndeiyi: girazi rakaumbwa negirazi fiber preform inoiswa pamusoro peairbag, iyo izere nemhepo uye yobva yawedzera kunze uye inovharirwa kune nzvimbo ye cathode mold, uye flange preform pakati pe cathode mold uye airbag inobatanidzwa uye inoporeswa.

Zvakanakira: kuwedzera kweiyo airbag kunogona kuita kuti resin iende kune chikamu che preform chisina kuisirwa, kuve nechokwadi chekuti preform yakanyatso kuisirwa neresin; iyo resin content inogona kugadziriswa nekumanikidzwa kweairbag; kudzvinyirirwa kunoitwa ne airbag kunoshandiswa kune mukati memukati we flange, uye flange mushure mekuporesa ine yakaderera porosity uye yakanaka mechanical properties. Kazhinji, mushure mekugadziriraFRPflange ine nzira iri pamusoro yekuumba, iyo yekunze yekunze yeflange inofanirawo kugadziriswa maererano nezvinodiwa zvekushandiswa kwekutendeuka nekuchera kuburikidza nemakomba akapoteredza denderedzwa reflange.
