1. Kuumba nemaoko

Kugadzira nemaoko ekugadzira maflange epurasitiki akasimbiswa nefiberglass (FRP). Iyi nzira inosanganisira kuisa resin yakaiswa nemaoko.jira refiberglasskana kuti mati muforoma uye zvichiita kuti dziome. Maitiro acho ndeekuti: Kutanga, jira remukati rine resin rakawanda rinogadzirwa uchishandisa resin nejira refiberglass. Mushure mekunge jira remukati raoma, rinobviswa kubva muforoma, uye jira rechimiro rinogadzirwa. Resin inozokweshwa pamusoro peforoma uye mukati meforoma. Machira ejira refiberglass akachekwa kare anoiswa zvichienderana nehurongwa hwakatarwa hwekuisa zvinhu, jira rega rega richibatanidzwa uchishandisa roller kuti ive nechokwadi chekuti rinoiswa zvakanaka. Kana ukobvu hwaunoda hwawanikwa, gungano rinoporeswa uye rinobviswa.

Resin yematrix yekuumba nemaoko inowanzo shandisa epoxy kana unsaturated polyester, nepo zvinhu zvekusimbisa zviri zvepakati-alkali kanajira refiberglass risina alkali.

Zvakanakira: Zvishoma zvinodiwa pakushandisa, kugona kugadzira maflange asina kujairika, uye hapana zvirambidzo pahuwandu hwemaflange.

Zvakashata: Mafuro emhepo anogadzirwa panguva yekugayiwa kweresin anogona kukonzera maburi, zvichideredza simba remuchina; kushanda zvakanaka kwekugadzira; uye kupera kwepazasi kusina kuenzana.

2. Kuumba Kudzvanya

Kuumba zvinhu zvine simba rekuisa zvinhu mu flange mold uye kuzvigadzirisa uchishandisa muchina wekudzvanya. Zvinhu zvinoumba zvinhu zvakasiyana uye zvinogona kusanganisira fiber compounds dzakasanganiswa kana dzakaiswa muchimiro chepfupi, fiberglass cloth scraps dzakadzokororwa, fiberglass cloth rings/strips dzakaiswa mu resin-impregnated multi-layer fiberglass cloth, stacked SMC (sheet molding compound), kana fiberglass fabric prewoven preforms. Nenzira iyi, flange disk nemutsipa zvinoumbwa panguva imwe chete, zvichiwedzera simba remajoini uye kusimba kwechimiro chose.

Zvakanakira: Kururama kwakanyanya, kudzokororwa, kukodzera kugadzirwa otomatiki, kugona kugadzira maflange akaomarara ane mutsipa munhanho imwe chete, uye nzvimbo dzakapfava dzisingade kugadziriswa mushure mekugadzirisa.

Zvakashata: Mitengo yakawanda yeforoma uye zvipingamupinyi pahukuru hweflange nekuda kwezvirambidzo zvemubhedha wekudzvanya.

3. Kuumbwa kweResin Transfer (RTM)  

RTM inosanganisira kuisa fiberglass reinforcement muforoma yakavharwa, kubaya resin kuti inyudze mafibers, uye kuapisa. Maitiro acho anosanganisira:

• Kuisa fiberglass preform inoenderana ne flange geometry iri mu mold cavity.
• Kubaya resin ine viscosity yakaderera pasi pekupisa kwakarongwa uye kumanikidzwa kuti inyorovese preform uye ibvise mhepo.
• Kudziisa kuti flange igare zvakanaka uye ibviswe.

Ma resin anowanzo kuve polyester isina kuguta kana epoxy, nepo mamwe ma reinforcements anosanganisiramachira efiberglass anoenderera mberikana machira akarukwa. Zvinhu zvinozadza senge calcium carbonate, mica, kana aluminium hydroxide zvinogona kuwedzerwa kuti zviwedzere kunaka kana kuderedza mitengo.

Zvakanakira: Nzvimbo dzakatsetseka, kugadzirwa kwepamusoro, kushanda kweforoma yakavharwa (kuderedza kusvibiswa kwemhepo uye njodzi dzehutano), kurongeka kwefiber kwakanangana kuti ishande zvakanaka, mari shoma yekudyara, uye kushandiswa kwesimba shoma kwezvinhu/simba.

4. Kugadzira Resin Inobatsirwa neVacuum (VARTM)

VARTM inochinja RTM nekubaya resin pasi pevacuum. Maitiro acho anosanganisira kuvhara fiberglass preform pamold yechirume nebhegi revacuum, kubvisa mweya kubva mugomba remold, uye kudhonza resin mupreform kuburikidza ne vacuum pressure.

Zvichienzaniswa neRTM, VARTM inogadzira maflange ane porosity yakaderera, fiber yakawanda, uye simba remakanika rakakura.

5. Kuumbwa kwe resin inofambiswa ne airbag

Kugadzira mabhegi emhepo (Airbag-assisted RTM molding) imhando yetekinoroji yekuumba yakagadzirwa zvichibva paRTM. Maitiro ekugadzira maflange nenzira iyi yekuumba ndeekuti: preform yegirazi yakaita seflange inoiswa pamusoro pebhegi remhepo, iro rinozadzwa nemhepo uye robva rapararira kunze uye rinovharirwa panzvimbo ye cathode mold, uye flange preform iri pakati pe cathode mold ne airbag inodzvinyirirwa uye inorapwa.

Zvakanakira: kuwedzera kwe airbag kunogona kuita kuti resin ienderere kuchikamu che preform chisina kunyudzwa, zvichiita kuti preform inyudzwe zvakanaka ne resin; huwandu hwe resin hunogona kugadziriswa nekumanikidzwa kwe airbag; kumanikidzwa kunoitwa ne airbag kunoiswa pamusoro pemukati me flange, uye flange mushure mekuoma kwayo ine porosity shoma uye hunhu hwakanaka hwemakanika. Kazhinji, mushure mekugadziriraFRPflange nenzira yekuumba iri pamusoro apa, pamusoro peflange inofanirawo kugadziriswa zvichienderana nezvinodiwa zvekushandisa kutenderedza nekuboora maburi akatenderedza flange.
