Kuyambira m'ma 1960, makampani opanga magalimoto adatengera ma polyurethanes kuti azigwiritsa ntchito zambiri.Pambuyo pa kupangidwa kwa polyurethane (PU thovu) mu 1954, opanga magalimoto anayamba kuphatikizira thovu lolimba la PU mumagulu a magalimoto ambiri.Masiku ano, sagwiritsidwa ntchito pamapanelo okha komanso mipando yamagalimoto, ma bumpers, ma insulators oyimitsa ndi zina zambiri zamkati.

Kugwiritsa ntchito thovu la polyurethane kumatha kupititsa patsogolo luso la wogwiritsa ntchito komanso magwiridwe antchito agalimoto kudzera:

• Kutsika kwamafuta abwinoko chifukwa cha kuchepa kwa thupi
• Chitonthozo
• Kukana kuwonongeka ndi dzimbiri
• Kuteteza kutentha
• Phokoso ndi mphamvu mayamwidwe

Kusinthasintha

Mapangidwe ndi kupanga mipando ya galimoto ndi yofunika kwambiri.Monga tafotokozera kale, kalembedwe, chitonthozo ndi chitetezo ndizinthu zazikulu zomwe ziyenera kuganiziridwa pamayendedwe amakono.Mipando yokhazikika tsopano imapangidwa pogwiritsa ntchito thovu la polyurethane.Monga zakuthupi, zimapereka chitonthozo ndi chithandizo popanda kutaya mawonekedwe ake, thovu la PU limatha kupangidwanso mosiyanasiyana, kumapereka chitonthozo chowonjezereka ndi luso la mapangidwe.Chithovu cha polyurethane chikhozasungani mawonekedwe akekwa zaka zambiri, popanda bunching kapena kukhala wosiyana.

Kusavuta Kugwiritsa Ntchito

Foam ya polyurethane imapangitsa kukhala kosavuta kwa opanga kuumba ndi kusema mawonekedwe kuti agwirizane ndi mapangidwe.Kusavuta kupanga ma cushion ndi ma prototypes a PU pogwiritsa ntchito Computer-Aided Design (CAD) kumapangitsa kukhala chinthu chodziwika bwino kwa opanga ndi opanga magalimoto padziko lonse lapansi.PU thovu imayamikanso kugwiritsa ntchito ukadaulo m'magalimoto, ndikutha kuphatikizira mawaya okhala ndi malo otentha komanso makina otikita minofu.

Mphamvu Mwachangu

Chiyambireni kumakampani oyendetsa magalimoto, polyurethane yathandizira kuchepetsa kukhudzidwa kwathu pa chilengedwe chifukwa cha kupepuka kwake.Kuchepetsa kulemera m'galimoto kumatanthauza kuti machitidwe a galimoto amawonjezeka chifukwa cha kuchepetsa kugwiritsira ntchito mafuta.

Chitetezo

Kukhala pansi kumagwira ntchito yofunika kwambiri pachitetezo cha kapangidwe ka galimoto.Pakachitika ngozi yagalimoto, mpando umayenera kuyamwa mphamvu kuchokera kwa wogwiritsa ntchito, komanso kuwateteza ku mawonekedwe amkati mkati mwampando.Polyurethane ili ndi mphamvu zochulukirapo pakulemera kwake, zomwe zimapangitsa kuti ikhale yopepuka koma yolimba kuti zisawonongeke.

Mapangidwe a mipando yamagalimoto amaphatikizidwanso ndi zomwe zimadziwika kuti chitetezo chokhazikika, chomwe (pogwiritsa ntchito chithandizo chotsatira), chimasunga thupi ndi mfundo zazikulu za mapewa, chiuno ndi miyendo pamalo otetezeka panthawi ya ngozi.

Chitonthozo

Pamsika wamagalimoto wamasiku ano, mipando ikuyembekezeka kukhala yopangidwa bwino, ergonomic komanso yabwino.Kupatula mwachiwonekere kupereka pamwamba kunyamula dalaivala kapena wokwera;cholinga china cha mpando wa galimoto ndi kupereka chitetezo pothandizira thupi la wogwiritsa ntchito pamene atayima kwa nthawi yaitali.Kuyenda maulendo ataliatali pafupipafupi kumasokoneza munthu ngati kaimidwe kake kamakhala koyipa paulendo wonse.Mapangidwe a mipando wamba amaphatikiza zinthu zingapo zoyimitsidwa m'munsi mwa mpando, monga akasupe ndi thovu la PU.

Chidziwitso:Zina mwazinthu / zithunzi zomwe zili m'nkhaniyi zikuchokera pa intaneti, ndipo gwero ladziwika.Amangogwiritsidwa ntchito kufotokoza mfundo kapena malingaliro omwe afotokozedwa m'nkhaniyi.Amangolankhulana ndi kuphunzira, ndipo sizinthu zina zamalonda.Ngati pali kuphwanya kulikonse, chonde titumizireni kuti tichotse nthawi yomweyo.
