Lipoti Loletsa Kudzikundikira kwa Ma Jenereta a Dizilo Okhala ndi Ziwiya

4. Kapangidwe ndi Zolinga za Dongosolo Loletsa Kudzimbidwa

5. Kuyenda Kwatsatanetsatane kwa Njira Yotsutsana ndi Kutupa

5.1 Njira Yolimbana ndi Kudzikundikira kwa Thupi Yokhalitsa (Chitsulo cha Channel)
Chitsulocho, chomwe chimagwira ntchito ngati maziko a chipangizocho ndipo nthawi zonse chimakhala pafupi ndi nthaka, chimatha kukokoloka chifukwa cha madzi ambiri, chinyezi, mchere, ndi zina zotero. Chifukwa chake, njira yolimbana ndi dzimbiri ya "heavy-duty" imagwiritsidwa ntchito.

1. Kuchiza Pamwamba Patsogolo - Kuphulika Kosakhazikika (Sa 2.5 Giredi)
   • Cholinga: Chotsani bwino chivundikiro cha mphero, dzimbiri, kutayira kwa weld, madontho a mafuta, ndi zina zonse zodetsa pamwamba pa chitsulo, ndikupanga chitsulo choyera komanso chouma ndikuwonjezera kukhwima kwa pamwamba kuti muwonjezere kwambiri kumatirira kwa chophimba.
   • Muyezo: Pogwiritsa ntchito chitsulo chotsukira kapena grit ngati chotsukira, pangani mulingo woyeretsera wa Sa 2.5 (Very Thorough Blast Cleaning), zomwe zimapangitsa kuti mawonekedwe achitsulo akhale ofanana komanso mawonekedwe a pamwamba (kukhwima) olamulidwa pakati pa 40-75µm.
2. Chitsulo Choteteza - Zinc Spray
   • Cholinga: Ikani chivundikiro cha zinc choyera kwambiri pamwamba pa chitsulo choyeretsedwa pogwiritsa ntchito mankhwala otentha. Chivundikiro cha zinc chimagwira ntchito ngati anode yotetezera, kupereka chitetezo cha cathodic ku chitsulocho. Ngakhale chivundikirocho chikawonongeka pang'ono, zinc idzawononga kwambiri, kuteteza chitsulo chomwe chili pansi pake.
   • Magawo a Njira: Kukhuthala kwa zinki osapitirira 80µm. Njira yopopera iyenera kukhala yofanana, popanda kuphonya.
3. Choteteza Chotchinga - Utoto Wolemera wa Bituminous
   • Cholinga: Pakani utoto wa bituminous wochita bwino kwambiri pamwamba pa wosanjikiza wothira zinc. Utoto wa bituminous umapereka kukana bwino madzi, chinyezi, dzimbiri la nthaka, komanso kukhazikika kwa mankhwala, zomwe zimapangitsa kuti pakhale chotchinga cholimba chomwe chimachotsa chinyezi ndi mpweya.
   • Chofunikira pa Ntchito: Gwiritsani ntchito kupopera kopanda mpweya wambiri kuti muwonetsetse kuti ngodya zonse ndi ma welds zimaphimbidwa mofanana. Ikani ma coat osachepera awiri, kuti mukhale ndi makulidwe onse a Dry Film (DFT) osachepera 200µm. Filimu yotsukidwa iyenera kukhala yosalala pokhudza, yopanda kutsika, kuthamanga, thovu, kapena zolakwika zina.

5.2 Njira Yopewera Kudzikundikira kwa Ma Panel a Thupi ndi Malo Akunja
Mapanelo a thupi amafunikira chitetezo cha dzimbiri komanso kukongola, motero dongosolo lophatikizana la primer + topcoat limagwiritsidwa ntchito.

1. Kuchiza Patsogolo Pamwamba - Kuchiza Patsogolo kwa Mankhwala
   • Kuyenda kwa Njira: Kuchotsa mafuta (kuchotsa mafuta) → Kutsuka → Phosphating (imapanga utoto wosintha phosphate womwe umathandiza kukana dzimbiri ndi kumatira utoto) → Kutsuka → Kuumitsa.
   • Muyezo: Gawo la kristalo la phosphate liyenera kukhala losalala, losalekeza, komanso lofanana.
2. Chophimba cha Primer - Chophimba cha Primer cholemera mu Epoxy Zinc
   • Cholinga: Imapereka ntchito yabwino kwambiri yolimbana ndi dzimbiri komanso ntchito yoteteza cathodic (mfundo yofanana ndi kupopera zinc). Dongosolo la epoxy resin limapereka kukana kwabwino kwa mankhwala ndi kumatira.
   • Chofunikira pa Ntchito: Thirani ma coat 1-2, kuti mukhale ndi makulidwe a Dry Film (DFT) osachepera 50µm.
3. Chophimba cha Topcoat - Chosagwira UV / Choletsa kukalamba Topcoat
   • Cholinga: Monga gawo lakunja, limapirira mwachindunji zinthu zachilengedwe monga kuwala kwa dzuwa, mvula, ndi kusintha kwa kutentha. Timagwiritsa ntchito polyurethane topcoat yogwira ntchito bwino kwambiri.
   • Makhalidwe:
     • Kukana Kwabwino Kwambiri kwa UV: Ili ndi zoyamwitsa za UV ndi zokhazikika, zomwe zimachepetsa kutha kwa utoto ndi kutayika kwa kuwala komwe kumachitika chifukwa cha kuwala kwa dzuwa.
     • Kuletsa kukalamba: Filimu ya utotoyi ili ndi kusinthasintha kwabwino, imatha kupirira kutentha ndi kukhuthala, ndipo siimatha kusweka kapena kudulidwa choko.
     • Kusunga Utoto Wautali & Kuwala Kwambiri: Kapangidwe kapamwamba kamatsimikizira kuti palibe kutha, kutayika kwa kuwala, kapena choko mkati mwa zaka 10.
   • Chofunikira pa Ntchito: Thirani ma coat awiri, kuti mukhale ndi makulidwe a Dry Film (DFT) osachepera 50µm. Mtundu uyenera kukhala wofanana komanso wofanana, wokhala ndi mawonekedwe osalala, osalala opanda peel ya lalanje, kutsika, kuthamanga, kapena tinthu tating'onoting'ono.

6. Kuyang'anira ndi Kulamulira Ubwino

• Kuyang'anira mkati mwa ndondomekoyi: Kuyang'anira ndi kulemba 100% gawo lililonse la ndondomeko (kuyeretsa ndi kupukuta kwa pulofayi, makulidwe a zinc layer, makulidwe a utoto wa utoto payokha).
• Kuyendera Komaliza:
  • Maonekedwe: Filimu ya utoto iyenera kukhala yosalala, yofanana ndi mtundu, yopanda ming'alu, kusweka, kutsika, kuyendayenda, thovu, mikwingwirima, kapena zolakwika zina zilizonse. Yosalala pokhudza.
  • Kuwunika Kukhuthala kwa Filimu: Gwiritsani ntchito maginito kapena eddy current thickness gauges kuti muyese makulidwe onse a dry film pa malo osiyanasiyana, kuonetsetsa kuti mukutsatira zofunikira pa kapangidwe kake.
  • Mayeso Otsatira: Chitani mayeso odulira mbali zonse ziwiri, ndikupeza chizindikiro cha 0 kapena 1 (popanda kuchotsa utoto).

7. Mapeto
Ma jenereta a dizilo okhala ndi ziwiya zomwe timapereka, kudzera mu njira zodzitetezera dzimbiri zomwe zafotokozedwa pamwambapa, zimaphatikizapo njira yotetezera yokhala ndi zigawo zambiri kuphatikiza "chitetezo cha cathodic" ndi "chitetezo cha zotchinga zakuthupi." Dongosololi limalimbana bwino ndi dzimbiri m'malo osiyanasiyana ovuta, likukwaniritsa mokwanira ndikupitilira zofunikira zaukadaulo za "zaka 30 popanda dzimbiri pa chassis ndi zaka 10 popanda kufota, kusungunuka, kapena choko cha topcoat ya thupi." Izi zimatsimikizira kudalirika kwakukulu komanso kukongola kwa jenereta panthawi yonse ya moyo wake.
