M'malo omwe akukula mwachangu pamsika wamagalimoto, kuphatikiza kwaukadaulo watsopano wamagetsi kwadzetsa kuwonekera kwa magalimoto amagetsi ndi osakanizidwa, omwe amadziwika kuti new energy vehicles (NEVs).Zina mwazinthu zomwe zimagwira ntchito yofunika kwambiri pamagalimotowa ndi zida zapulasitiki.Zida zapulasitiki zopepuka komanso zolimbazi zimathandizira kuti ma NEV azitha kuchita bwino, kugwira ntchito, komanso kukhazikika.Nkhaniyi ikufuna kufufuzidwa mu chidziwitso cha zigawo za pulasitiki m'magalimoto atsopano amphamvu, ndikuwunikira njira zawo zopangira, kusankha zinthu, ndi ubwino.
**Njira Zopangira:**
Zida za pulasitiki mu NEVs amapangidwa pogwiritsa ntchito njira zosiyanasiyana zopangira zomwe zimatsimikizira kulondola, khalidwe, ndi mphamvu.Njira zina zodziwika bwino ndi monga jekeseni, kuponderezana, ndi thermoforming.Kumangira jekeseni, pokhala njira yogwiritsiridwa ntchito kwambiri, kumaphatikizapo kubaya pulasitiki wosungunuka m’bowo la nkhungu, mmene amaziziritsira ndi kulimba kupanga mawonekedwe ofunikira.Njirayi imakondedwa chifukwa cha kuthekera kwake kupanga mapangidwe ovuta komanso ovuta komanso obwerezabwereza.
**Kusankha Zinthu:**
Kusankhidwa kwa zida zapulasitiki za zigawo za NEV ndizofunikira kwambiri chifukwa cha zofunikira zamagalimotowa, monga kuchepetsa kulemera, kukhazikika kwa kutentha, ndi kukana zinthu zachilengedwe.Zomwe zimagwiritsidwa ntchito nthawi zambiri ndi:
1. **Polypropylene (PP):** Wodziwika kuti ndi wopepuka komanso wosasunthika bwino, PP nthawi zambiri amagwiritsidwa ntchito pazinthu zamkati monga dashboards, mapanelo a zitseko, ndi mipando ya mipando.
2. ** Polyethylene Terephthalate (PET): ** PET imasankhidwa chifukwa chomveka bwino, ndikupangitsa kuti ikhale yoyenera kwa mazenera ndi zophimba zowonekera kwa masensa ndi makamera.
3. **Polyamide (PA/Nayiloni):** PA imapereka mphamvu zamakina apamwamba komanso kukana kutentha, zomwe zimapangitsa kuti zikhale zoyenera pazigawo zamapangidwe monga nyumba za batri ndi zolumikizira.
4. **Polycarbonate (PC):** PC imapereka kuwala kwapadera kwapadera komanso kukana mphamvu, zomwe zimapangitsa kuti zikhale zabwino kwa magalasi akumutu ndi magulu a zida.
5. **Thermoplastic Polyurethane (TPU):** TPU imagwiritsidwa ntchito kusindikiza ndi kugwetsa-damping ntchito chifukwa cha kusinthasintha kwake komanso kukana kuphulika.
6. **Polyphenylene Sulfide (PPS):** PPS imadziwika ndi kukana kwa mankhwala ndi kukhazikika pa kutentha kwakukulu, ndikupangitsa kuti ikhale yoyenera kwa zigawo pafupi ndi injini kapena batri.
**Ubwino wa Zida Zapulasitiki mu NEVs:**
1. **Kuchepetsa Kulemera:** Zigawo za pulasitiki ndizopepuka kwambiri kuposa zida zachitsulo, zomwe zimathandiza kuti galimoto ikhale yabwino komanso kuchuluka kwa batri.
2. **Kusinthasintha Kwakapangidwe:** Zipangizo zapulasitiki zimalola mapangidwe odabwitsa ndi mawonekedwe ovuta, zomwe zimathandiza opanga kukhathamiritsa ma aerodynamics ndi kugwiritsa ntchito malo.
3. ** Phokoso ndi Kugwedeza Kugwedezeka: ** Zida za pulasitiki zikhoza kupangidwa kuti zichepetse phokoso ndi kugwedezeka, kupititsa patsogolo luso la kuyendetsa galimoto.
4. **Kulimbana ndi Corrosion Resistance:** Pulasitiki ndi chibadwa chosamva dzimbiri, zomwe zimawapangitsa kukhala oyenera malo omwe ali pachiwopsezo cha chilengedwe.
5. **Thermal Insulation:** Mapulasitiki ena ali ndi zinthu zabwino kwambiri zotchinjiriza kutentha, zomwe zimathandiza kusunga kutentha mkati mwagalimoto ndi zigawo zofunika kwambiri.
Pomaliza, zigawo za pulasitiki zimagwira ntchito yofunika kwambiri pakupanga tsogolo la magalimoto amagetsi atsopano.Njira zawo zogwirira ntchito zosiyanasiyana, zosankha zosiyanasiyana, ndi maubwino angapo zimawapangitsa kukhala ofunikira kwambiri pakukwaniritsa zomwe akufuna, kuchita bwino, komanso kukhazikika kwa ma NEV.Pamene makampani oyendetsa magalimoto akupitilirabe kutengera luso lazopangapanga, zida zapulasitiki mosakayikira zikhala patsogolo pakupititsa patsogolo luso laukadaulo pofunafuna njira zothetsera mayendedwe obiriwira.
