Kodi ndingasakaniza G12 ndi G13 antifreeze?

Antifreeze G12 ndi G13. Kodi pali kusiyana kotani?

Madzi ambiri omwe amagwiritsidwa ntchito m'makina amakono ozizirira magalimoto amakhala ndi zinthu zitatu:

• mowa woyambira wa dihydric (ethylene glycol kapena propylene glycol);
• madzi osungunuka;
• phukusi la zowonjezera (anti-corrosion, protective, anti-foam, etc.).

Madzi ndi mowa wa dihydric amapanga zoposa 85% ya voliyumu yonse yozizirira. 15% yotsalayo imachokera ku zowonjezera.

Ma antifreeze a Gulu la G12, malinga ndi gulu lokhazikitsidwa, ali ndi magawo atatu: G12, G12 + ndi G12 ++. Pansi pamadzi onse amtundu wa G12 ndi ofanana: ethylene glycol ndi madzi osungunuka. Kusiyana kwagona pazowonjezera.

G12 antifreeze ili ndi zowonjezera za carboxylate (organic). Amagwira ntchito kuti apewe dzimbiri ndipo sapanga filimu yoteteza mosalekeza, monga m'kalasi ya G11 zoziziritsa kukhosi (kapena antifreeze m'nyumba). Madzi a G12+ ndi G12++ amakhala osinthasintha. Muli ndi zowonjezera zonse za organic ndi inorganic zomwe zimatha kupanga filimu yoteteza pamalo ozizirira, koma zowonda kwambiri kuposa momwe zimakhalira ndi zoziziritsa kukhosi za G11.

G13 antifreeze ili ndi maziko a propylene glycol ndi madzi osungunuka. Ndiko kuti, mowa wasinthidwa, zomwe zimatsimikizira kukana kwa kapangidwe kake kuzizira. Propylene glycol ndi yocheperako komanso yankhanza kwambiri kuposa ethylene glycol. Komabe, mtengo wa kupanga kwake ndi wokwera kangapo kuposa wa ethylene glycol. Pankhani ya magwiridwe antchito, pokhudzana ndi ntchito mu makina oziziritsa agalimoto, kusiyana pakati pa zakumwa zoledzeretsa kumakhala kochepa. Zowonjezera m'kalasi ya G13 antifreezes zimaphatikizidwa, zofanana mu khalidwe ndi kuchuluka kwa G12 ++ coolants.

Kodi G12 ndi G13 antifreeze angasakanizidwe?

Palibe yankho lotsimikizika ku funso loti ndizotheka kusakaniza makalasi a antifreeze G12 ndi G13. Zambiri zimatengera kapangidwe kakuzirala komanso kuchuluka kwa kusakaniza zamadzimadzi. Ganizirani zochitika zingapo zosakaniza G12 ndi G13 antifreezes.

1. M'dongosolo lomwe G12 antifreeze kapena zigawo zake zina zonse zadzazidwa, G20 antifreeze imawonjezeredwa pamlingo waukulu (kuposa 13%). Kusakaniza kotereku ndikovomerezeka, koma osavomerezeka. Mukasakanizidwa, zakumwa zoledzeretsa sizingagwirizane. Madzi omwe amapezedwa posakaniza antifreezes G12 ndi G13 asintha pang'ono malo oundana, koma kudzakhala kusintha pang'ono. Koma zowonjezera zimatha kutsutsana. Kuyesera kwa okonda pankhaniyi kunatha ndi zotsatira zosiyana, zosayembekezereka. Nthawi zina, mpweyawo sunawonekere ngakhale patapita nthawi yayitali komanso itatha kutentha. Nthawi zina, mukamagwiritsa ntchito mitundu yosiyanasiyana ya zakumwa kuchokera kwa opanga osiyanasiyana, turbidity yowoneka bwino idawonekera pazosakanizazo.

2. Mu dongosolo lopangidwira G13 antifreeze, kuchuluka kwakukulu (kuposa 20% ya voliyumu yonse) kumawonjezeredwa ku gulu la G12 lozizira. Izi sizingachitike. Mwachidziwitso, makina opangira antifreeze a G13 sayenera kupangidwa ndi zinthu zotetezedwa kwambiri ndi nkhanza za mankhwala, monga momwe zimafunikira pa machitidwe a G12 antifreeze. Propylene glycol ili ndi mphamvu yochepa ya mankhwala. Ndipo ngati wopanga magalimoto adagwiritsa ntchito mwayiwu ndikupanga zinthu zilizonse kuchokera kuzinthu zomwe sizinali zachikhalidwe, ndiye kuti ethylene glycol yaukali imatha kuwononga zinthu zomwe sizikhazikika pazotsatira zake.
3. Kuchuluka kwa G12 antifreeze kumawonjezeredwa ku dongosolo lomwe lili ndi G13 antifreeze (kapena mosiyana). Izi sizovomerezeka, koma ndizotheka pamene palibe njira ina yotulukira. Sipadzakhala zotsatira zovuta, ndipo mulimonse, iyi ndi njira yovomerezeka kuposa kuyendetsa galimoto popanda kuzizira mu dongosolo.

Mutha kusintha antifreeze ya G12 ndi G13. Koma izi zisanachitike, ndi bwino kutenthetsa dongosolo yozizira. M'malo mwa G13, simungathe kudzaza G12.

Antifreeze G13.. G12 Mix? 🙂
