Seat foam kazhinji inoreva polyurethane foam, iyo inogadzirwa nezvinhu zviviri-zvikamu pamwe nezvinowedzerwa zvinowirirana uye zvimwe zvidiki zvidiki, izvo zvinopushwa kuburikidza nekuumbwa.Iyo yese yekugadzira maitiro yakakamurwa kuita matatu maitiro: nhanho yekugadzirira, nhanho yekugadzira uye post-processing nhanho.
Kunyanya tarisa kana mvura yemukati uye viscosity yepolyether inosangana nezvinodiwa.Ichi chinhu chinonyanya kukosha munguva yechando kuchamhembe.
Kugadzirwa kwemahara foam kuyedzwa kunoitwawo kune zvinouya zvinhu, kunyanya kuyera kuti zvionekwe kuti zvinosangana nezvinodiwa zvekugadzira.
② kusanganisa:
Kusanganisa kunoitwa zvinoenderana neyakagadzikiswa fomula, uye otomatiki yekusanganisa michina iri kushandiswa parizvino.FAW-Volkswagen's chigaro foam system yakakamurwa kuita marudzi maviri: composite zvinhu uye self-musanganiswa zvinhu.
Combination material :) A + B miviri yakasanganiswa mhinduro inosanganiswa zvakananga
Kuzvibata wega: sanganisa POLY, kureva, basic polyether + POP + additives, wobva wasanganisa POLY uye ISO.
2. Danho rekugadzira - loop production
Kazhinji, kugadzirwa kwe loop kunogamuchirwa, kunyanya kuburikidza nemaitiro akati wandei sekudira, kuumba, kudhonzesa, uye kuchenesa mold, sezvinotevera:
Pakati pavo, kudurura ndiyo kiyi, iyo inonyanya kupedzwa nekudurura manipulator.Nzira dzakasiyana dzekudira dzinoshandiswa zvichienderana nenzvimbo dzakasiyana dzefuro rechigaro, ndiko kuti, mafuro munzvimbo dzakasiyana anodururwa, uye maparamendi ekuita akasiyana (kudzvanywa, tembiricha, fomula, furo density, nzira yekudurura, mhinduro index).
3. Post-processing stage – inosanganisira kuchera, kuchekerera, kukodha, kugadzirisa, kumwaya silencer wakisi, kuchembera nezvimwe.
① Gomba - Chinangwa chekuvhura ndechekudzivirira deformation yechigadzirwa uye kuwedzera elasticity.Yakakamurwa kuva vacuum adsorption mhando uye roller mhando.
Mushure mokunge furo richibuda mu mold, zvakakosha kuzarura masero nokukurumidza.Iyo ipfupi nguva, zviri nani, uye iyo yakareba nguva haifanirwe kudarika makumi mashanu.
②Edge trimming-foam Nekuda kwekuita kwe mold kupera, kumwe kupenya kwefuro kunogadzirwa pamucheto wefuro, izvo zvinokanganisa chitarisiko kana uchivhara chigaro uye zvinoda kubviswa nemaoko.
③ Coding - inoshandiswa kutsvaga zuva rekugadzira uye batch yefuro.
④Kugadzirisa - Foam inoburitsa hurema hudiki panguva yekugadzira kana dhizaini maitiro.Kazhinji, glue inoshandiswa kugadzirisa kukanganisa.Zvakadaro, FAW-Volkswagen inotaura kuti nzvimbo A haitenderwe kugadziriswa, uye kune akakosha emhando miyero yekudzora mashandiro ekugadzirisa..
⑤Pfaya wakisi inosveta ruzha - basa nderekudzivirira kupokana kuri pakati pefuro nechigaro chechigaro kuti uite ruzha.
⑥Kuchembera - Mushure mekunge furo raumbwa kubva muforoma, iyo inopupuma haiwanzo kubatwa zvizere, uye micro-reactions inodiwa.Kazhinji, furo rinomiswa mumhepo nekatenary kwemaawa 6-12 kurapa.

mushure-kuibva
Izvo chaizvo nekuda kwemaitiro akaomarara zvekuti chigaro cheVolkswagen furo chine nyaradzo yakanakisa uye kuchengetedzwa kwezvakatipoteredza nekunhuhwirira kwakaderera uye kubuda kwakaderera.
