Mushumo weMaitiro Ekudzivirira Kuora kweMaseti Ejenareta Edhiziri Akaiswa Mumidziyo

4. Kugadzira nezvinangwa zveSisitimu yeKurwisa Kuora

5. Kuyerera Kwakadzama Kwemaitiro Ekudzivirira Kuora

5.1 Maitiro Ekudzivirira Kuora Anogara Nguva Refu Ekushandisa Chassis Yemuviri (Simbi Yechiteshi)
Chassis, inoshanda sehwaro hwechivako cheyuniti inotakura mutoro uye inogara iri pedyo nepasi, inogona kukanganiswa nekuunganidzwa kwemvura, hunyoro, munyu, nezvimwewo. Saka, sisitimu yekudzivirira ngura yepamusoro-soro inoshandiswa.

1. Kurapa Pamusoro Pamberi - Kuputika Kwemvura (Sa 2.5 Grade)
   • Chinangwa: Bvisai zvakanaka chikero chemugayo, ngura, spatter yeweld, mavara emafuta, nezvimwe zvese zvinosvibisa pamusoro pesimbi, zvichiita kuti simbi ive yakachena uye yakaoma uye kuwedzera kuomarara pamusoro kuti zviwedzere kunamira kwependi.
   • Zvakajairika: Uchishandisa simbi yakapfura kana kuti grit senzira yekukwesha, tsvaga giredhi rekuchenesa reSa 2.5 (Very Thorough Blast Cleaning), zvichiita kuti chitarisiko chesimbi chifanane uye chimiro chepamusoro (roughness) chinodzorwa pakati pe40-75µm.
2. Rutivi Runodzivirira rweSimbi - Kupfapfaidza Zinc
   • Chinangwa: Isa jira rezinc rakacheneswa zvakanyanya pamusoro pesimbi yakacheneswa uchishandisa thermal spray. Zinc layer inoshanda seanode yekubikira, ichipa dziviriro yecathodic kusimbi. Kunyangwe kana jira racho rikakuvara zvishoma, zinc ichaora zvakanyanya, ichidzivirira simbi iri pasi payo.
   • Maitiro ekugadzirisa: Ukobvu hwezinki husingasviki 80µm. Maitiro ekupfapfaidza anofanira kunge akafanana, pasina kupotsa.
3. Rutivi Runodzivirira - Pendi yeBituminous ine basa guru
   • Chinangwa: Isa pendi yebhituminous inoshanda zvakanyanya pamusoro pechikamu chakapfapfaidzwa ne zinc. Pendi yebhituminous inodzivirira mvura, hunyoro, ngura yevhu, uye kugadzikana kwemakemikari, zvichiita kuti pave nechidziviriro chakasimba chinoparadzanisa hunyoro neokisijeni zvinobudirira.
   • Chinodiwa Chekushandisa: Shandisa kupfapfaidza kusina mhepo yakawanda kuti uve nechokwadi chekuti makona ese uye ma welds akafukidzwa zvakaenzana. Isa kanenge kaviri, zvichiita kuti Dry Film Ukobvu (DFT) husapfuure 200µm. Firimu rakacheneswa rinofanira kunge rakatsetseka pakubata, risina kudonha, kuyerera, mabhubhu, kana zvimwe zvikanganiso.

5.2 Maitiro Ekudzivirira Kuora KwemaPaneru Emuviri Nekunze
Mapaneru emuviri anoda dziviriro yengura uye runako, saka system ye primer + topcoat inoshandiswa.

1. Kurapa Kwepamusoro - Kurapa Kwemakemikari Kwepamberi
   • Kuyerera Kwemaitiro: Kubvisa mafuta (kubvisa mafuta) → Kusukurudza → Phosphating (inogadzira chifukidziro chekuchinja phosphate chinowedzera kuramba ngura uye kunamira kwependi) → Kusukurudza → Kuomesa.
   • Zvakajairika: Fosfeti crystal layer inofanira kunge yakatsetseka, isingaperi, uye yakafanana.
2. Kuputira Primer - Primer ine Epoxy Zinc yakawanda
   • Chinangwa: Inopa simba rakanaka rekudzivirira ngura uye basa rekudzivirira cathodic (pfungwa yakafanana neyokupfapfaidza zinc). Sisitimu ye epoxy resin inopa simba rakanaka rekudzivirira makemikari uye kunamira.
   • Chinodiwa Chekushandisa: Pfapfaidza 1-2 coats, zvichiita kuti Dry Film Ukobvu (DFT) husapfuure 50µm.
3. Kupfeka Topcoat - Inodzivirira UV / Inodzivirira kukwegura Topcoat
   • Chinangwa: Sechikamu chekunze, inotsungirira zvakananga zvinhu zvakaita sezuva, mvura, uye kuchinja kwekupisa. Tinoshandisa polyurethane topcoat inoshanda zvakanyanya.
   • Hunhu:
     • Kudzivirira Kwakanaka kweUV: Ine zvinotora UV zvinodzikamisa uye zvinoderedza kupenya kwemavara uye kurasikirwa nechiedza kunokonzerwa nekuratidzwa kwezuva.
     • Kudzivirira kukwegura: Pendi iyi inochinjika zvakanaka, inogona kutsungirira kupisa kukuru uye kudzikira, uye haikurumidzi kutsemuka kana kukwenywa nechoko.
     • Kuchengetedza Ruvara Rwakanyanya & Kupenya: Kugadzirwa kwepamusoro kunoita kuti pasave nekuoma, kurasikirwa nekupenya, kana choko mukati memakore gumi.
   • Chinodiwa Chekushandisa: Pfapfaidza kaviri, zvichiita kuti Dry Film Ukobvu (DFT) husapfuure 50µm. Ruvara runofanira kunge rwakafanana uye rwakafanana, ruine chitarisiko chakatsetseka, chisina ganda reorenji, madonhwe, madonhwe, kana zvidimbu.

6. Kuongorora uye Kudzora Hunhu

• Kuongorora mukati mekuita basa: Kuongorora nekunyora nhanho yega yega yekushanda (kuchena kwekuputika uye chimiro, ukobvu hwezinc layer, ukobvu hwependi yega yega).
• Kuongorora Kwekupedzisira:
  • Chitarisiko: Pendi inofanira kunge yakatsetseka, ine ruvara rwakafanana, isina maburi, maburi, maburi, mavanga, kana zvimwe zvikanganiso. Yakanyatsonaka kusvika yabatwa.
  • Kuongorora Ukobvu hweFirimu: Shandisa magauge eukobvu hwemagetsi kana eddy current kuti uverenge ukobvu hwese hwemafirimu akaoma panzvimbo dzakasiyana-siyana, uchivimbisa kuti zvinodiwa pakugadzira zvinoenderana nezvinodiwa.
  • Muedzo weKunamatira: Ita bvunzo yekuenzanisa zvidimbu zvakasiyana, uchiwana chiyero che 0 kana 1 (hapana kubviswa kwependi).

7. Mhedziso
Seti dzejenareta dzedhiziri dzine makontena dzatinopa, kuburikidza nemaitiro akarongeka uye akajairwa ekudzivirira ngura atsanangurwa pamusoro apa, dzinosanganisira sisitimu yekudzivirira ine mativi akawanda inosanganisa "dziviriro yecathodic" uye "dziviriro yezvidziviriro zvemuviri." Sisitimu iyi inodzivirira ngura zvinobudirira munzvimbo dzakasiyana-siyana dzakaoma, ichizadzisa zvizere uye ichipfuura zvinodiwa zvehunyanzvi zve "makore makumi matatu pasina ngura yechasi uye makore gumi pasina kupera, oxidation, kana chaki ye body topcoat." Izvi zvinoita kuti jenareta ive yakavimbika uye inoyevedza muhupenyu hwayo hwese.
