Autoplasticine. Njira yosavuta yothetsera mavuto ovuta

The zikuchokera autoplasticine

Kuyambira nthawi imeneyo, mapangidwe a plasticine sanasinthe kwambiri, kotero ena eni galimoto ngakhale panopa m'mikhalidwe yovuta amayendetsa ndi plasticine wamba ana, umboni ndi ndemanga zambiri. Chomaliza, chifukwa pulasitiki yotere imatha kukhala yamitundu yambiri.

Kapangidwe ka mankhwala kumaphatikizapo:

• Gypsum ntchito monga filler - 65%.
• Vaseline - 10%.
• Madzi - 5%.
• Kusakaniza kwa lanolin ndi stearic acid - 20%.

Kuti zigwiritsidwe ntchito muzinthu zamagetsi zamagalimoto, zida zapadera zimawonjezeredwa ku pulasitiki yachikhalidwe yomwe imayimitsa njira za dzimbiri.

Autoplasticine amapangidwa pa maziko awiri - madzi kapena mafuta, ndipo onse ntchito kuteteza magalimoto. Gulu loyamba limadziwika ndi kutha kuwuma mumlengalenga, ndikusunga mawonekedwe ake oyambirira (chinthuchi chimagwiritsidwa ntchito posindikiza zimfundo ndi mipata). Gulu lachiwiri ndi exfoliating autoplastics, ndi pulasitiki ndipo siziuma, chifukwa chake amagwiritsidwa ntchito ngati anti-corrosion agent pamunsi ndi ziwalo zina zagalimoto.

Kodi autoplasticine ndi chiyani?

Kugwiritsa ntchito kwakukulu kwa mankhwalawa:

1. Chitetezo cha ma bolts ku dzimbiri.
2. Monga anticorrosive wothandizira (pamodzi ndi chosinthira dzimbiri).
3. Kusindikiza mbali imodzi ya thupi.

Autoplasticine imagwiritsidwa ntchito kuteteza mafupa ndi mipata pansi pa galimoto ku tinthu tating'onoting'ono. Izi zimathandizira kuchotsedwa kwawo potsuka ndi shampu yagalimoto kapena madzi osavuta, pomwe chophimba chachikulu sichikuwonongeka. Pambuyo pake, kukonza kowonjezera ndi ma-sealants atha kuchitidwa.

Pofuna kuteteza dzimbiri, ma autoplastic opangidwa ndi madzi amagwiritsidwa ntchito (zolinga ndi mapangidwe ake nthawi zambiri zimawonetsedwa pakupanga kwazinthu). Chisindikizo choterocho chimagwira bwino pamtunda uliwonse, sichimawonekera ndi kuwala kwa dzuwa, sichikhala ndi poizoni, ndipo sichiwola, ngakhale pamtunda wa sulfure dioxide, nitrogen kapena carbon dioxide mumlengalenga.

Ndi kugwiritsa ntchito mosalekeza, zinthuzo zimathandizira kuchepetsa phokoso la injini yothamanga: kuyamwa kwamawu kumatsimikiziridwa ndi kapangidwe kazinthu zama cell. Njirayi ndi yothandiza makamaka kwa malo omwe ali m'galimoto momwe sizingatheke kugwiritsa ntchito sealant yamadzimadzi. Izi zikuphatikiza kuphatikizika kwa mapiko agalimoto okhala ndi khomo, mapiko opindika, ma laisensi, zolumikizira zomangira ma brake hoses ndi machubu. Pamapeto pake, kukonza kwawo kowonjezera kumachitidwa nthawi imodzi.

Mayendedwe akugwiritsa ntchito limodzi kwa autoplasticine ndi chosinthira dzimbiri ndi motere. Pamwamba pake amawuma bwino ndikutsukidwa. Choyamba, chosinthira chimagwiritsidwa ntchito, ndiyeno madera ovuta (zomangira, ma wheel arch liners, ma bumpers amkati) amakonzedwanso ndi autoplasticine. Ndemanga zina za ogwiritsa ntchito zikuwonetsa kuti autoplasticine yokha ingagwiritsidwe ntchito, makamaka posindikiza bolt ndi mitu ya mtedza, popeza mtundu wapachiyambi wa chosindikizira chotere umasungidwa kwa zaka zingapo.

Malamulo oyambira kusankha

Ndikoyenera kusankha autoplasticine osati pamtengo wake, koma chifukwa cha zomverera zake: chinthu chofewa chimakhala chowoneka bwino, ndipo, ngakhale kuti ndichosavuta kugwiritsa ntchito, chimakhala choyipa kwambiri pamapeto pake. Plasticine yolimba ndiyosavuta kupereka mawonekedwe omwe mukufuna.

Zomwe zimamatira za autoplasticines zamakono sizidalira zinthu zomwe zimasindikizidwa, choncho ndi bwino kusankha mankhwala molingana ndi kugwirizana ndi mapangidwe a zigawozo, poyang'ana ntchito yomwe ikuyenera kuchitidwa.

Zoperewera za mankhwalawa zikuphatikizapo kuti autoplasticine yokhala ndi madzi imataya kusungunuka kwake mu chisanu choopsa, kusweka m'malo omwe amagwiritsidwa ntchito. Kuyesa kugwiritsa ntchito mafuta osungunuka m'mafuta sikupambananso makamaka, chifukwa pa kutentha kochepa, autoplasticine simakhuthala ndi delaminate. Mwa njira, chinthucho chimakhalanso chosayenera kutentha pamwamba pa 30 ... 35ºС, chifukwa chimayamba kusungunuka.
