Ngingakwazi ukuhlanganisa i-Gif ne-G11 antifreeze?

I-Antifreeze G11 ne-G12. Uyini umehluko?

Iningi lamapholisa (coolants) wezimoto zomphakathi zenziwa ngesisekelo se-dihydric alcohols, i-ethylene noma i-propylene glycols, namanzi acwecwe. Amanzi notshwala kwenza ngaphezu kwamaphesenti angama-90 wesamba se-antifreeze. Ngaphezu kwalokho, izilinganiso zalezi zingxenye ezimbili zingase zihluke kuye ngokuthi izinga lokushisa elidingekayo lokuqandisa lesipholisi. I-antifreeze esele igcwele izithasiselo.

I-G11 antifreeze, njengozakwabo wasekhaya ocishe uphelele i-Tosol, nayo iqukethe i-ethylene glycol namanzi. Lawa ma-antifreeze asebenzisa izinhlanganisela ze-inorganic, ama-phosphates ahlukahlukene, ama-borates, ama-silicates nezinye izakhi njengezithasiselo. Izinhlanganisela ze-Inorganic zisebenza ngaphambi kwejika: emahoreni ambalwa ngemva kokugcwalisa ohlelweni, zenza ifilimu evikelayo ezindongeni zesekethe yonke yokupholisa. Ifilimu ilenga imiphumela enolaka yotshwala namanzi. Kodwa-ke, ngenxa yesendlalelo esengeziwe phakathi kwejazi lokupholisa kanye nesipholile, ukusebenza kahle kokususa ukushisa kuncipha. Futhi, impilo yesevisi yama-antifreeze ekilasi le-G11 anezithasiselo ezingaphili ifushane futhi iphakathi kweminyaka emi-3 ngomkhiqizo wekhwalithi.

I-antifreeze ye-G12 nayo yenziwa ngengxube yamanzi ne-ethylene glycol. Nokho, izithasiselo kuwo kukhona organic. Okungukuthi, ingxenye eyinhloko yokuvikela ngokumelene nolaka lwe-ethylene glycol ku-antifreeze ye-G12 i-carboxylic acid. Izithasiselo ze-Organic carboxylate azenzi ifilimu ye-homogeneous, ukuze amandla okukhipha ukushisa angehli. Izinhlanganisela ze-Carboxylate zisebenza ngendlela eqondile, ikakhulukazi endaweni yokugqwala ngemuva kokuvela kwazo. Lokhu kunciphisa kancane izakhiwo zokuzivikela, kodwa akuthinti izakhiwo ze-thermodynamic zoketshezi. Ngesikhathi esifanayo, ama-antifreeze anjalo asebenza cishe iminyaka emi-5.

Ama-antifreeze e-G12+ kanye ne-G12++ aqukethe izithasiselo eziphilayo nezingaphili. Ngesikhathi esifanayo, kunezithasiselo ezimbalwa ze-inorganic ezakha ungqimba oluvikela ukushisa kulawa mapholisa. Ngakho-ke, ama-antifreeze e-G12 + ne-G12 ++ awaphazamisi ukususwa kokushisa futhi ngesikhathi esifanayo abe namadigri amabili okuvikela.

Ingabe ama-antifreeze e-G11 kanye ne-G12 angaxutshwa?

Ungaxuba ama-antifreeze e-G11 kanye ne-G12 ezimweni ezintathu.

1. Ungakwazi ukugcwalisa ngokukhululekile esikhundleni se-antifreeze ye-G11 enconyiwe ene-coolant yekilasi G12 ++, futhi uhlanganise lezi zipholile ezimbili kunoma yiziphi izilinganiso. I-Antifreeze G12 ++ iyindawo yonke, futhi uma ishintsha indlela yokusebenza yesistimu yokupholisa, kusho ukuthi ayibalulekile. Ngasikhathi sinye, izici zokuvikela zalesi sigaba sokupholisa ziphakeme, futhi iphakethe lesengezo elithuthukisiwe lizovikela ngokuthembekile noma iyiphi isistimu ekugqwaleni.
2. Esikhundleni se-G11 antifreeze, ungagcwalisa i-G12 + ngesizathu esifanayo esichazwe endimeni yokuqala. Kodwa-ke, kulokhu, kungase kube nokuncipha kancane kwezinsiza zezakhi zomuntu ngamunye zesistimu yokupholisa injini.
3. Ungakwazi ukwengeza ngokuphephile komunye nomunye ngamanani amancane, kufika ku-10%, ama-antifreeze brand G11 kanye ne-G12 (kuhlanganise nazo zonke izinguquko zabo). Iqiniso liwukuthi izithasiselo zalezi zipholile aziphuli futhi azidli ngesikhathi sokusebenzisana, kodwa kuphela ngombandela wokuthi uketshezi ekuqaleni lusezingeni eliphezulu futhi lwenziwa ngokuhambisana nezindinganiso.

Kuvunyelwe, kodwa akunconyiwe, ukugcwalisa isipholile sekilasi G11 esikhundleni se-G12 antifreeze. Ukungabikho kwezithasiselo ezingaphili kunganciphisa ukuvikelwa kwezingxenye zenjoloba nezensimbi futhi kunciphise impilo yesevisi yezakhi zohlelo ngalunye.

Akunakwenzeka ukugcwalisa i-G12 epholile kanye nesinqamuleli se-G11 esidingekayo. Lokhu kuzothinta kabi amandla okukhipha ukushisa futhi kungaholela nasekubilisweni kwenjini.
