Ngingakwazi yini ukuhlanganisa i-G12 ne-G12 + i-antifreeze?

I-antifreeze ene-G12+ ne-G12. Uyini umehluko?

Zonke izinto zokupholisa ezilebulwe ngokuthi i-G12 (kanye nezinguqulo ze-G12+ ne-G12++) zihlanganisa i-ethylene glycol, amanzi acwengekile kanye nephakheji elengeziwe. Amanzi kanye ne-dihydric alcohol ethylene glycol yizici ezibalulekile cishe kuwo wonke ama-antifreeze. Ngaphezu kwalokho, izilinganiso zalezi zingxenye eziyisisekelo zama-antifreeze emikhiqizo ehlukene, kodwa ngamazinga okushisa afanayo, awashintshi.

Umehluko omkhulu phakathi kwe-G12 + ne-G12 antifreeze usezithasiselweni.

I-antifreeze ye-G12 yathatha indawo yomkhiqizo we-G11, owawuphelelwe isikhathi ngaleso sikhathi (noma i-Tosol, uma sicabangela izinto zokupholisa zasekhaya). Izithasiselo ze-Inorganic kuma-antifreeze ezipholile eziphelelwe yisikhathi, ezakha ifilimu evikelayo eqhubekayo endaweni engaphakathi yesistimu yokupholisa, zine-drawback eyodwa ebalulekile: zehlisa amandla okudlulisa ukushisa. Ezimweni lapho umthwalo enjini yomlilo yangaphakathi wanda, isixazululo esisha, esisebenza kahle sasidingeka, njengoba ama-antifreezes ajwayelekile ayengakwazi ukubhekana nokupholisa ama-motor "ashisayo".

Izithasiselo ze-inorganic ku-antifreeze ye-G12 zithathelwe indawo yi-organic, carboxylate. Lezi zingxenye azizange zimboze amapayipi, ama-honeycombs e-radiator kanye nejazi lokupholisa ngesendlalelo sokushisa ukushisa. Izithasiselo ze-Carboxylate zakha ifilimu yokuzivikela kuphela ezilonda, ezivimbela ukukhula kwazo. Ngenxa yalokhu, ukuqina kokudluliswa kokushisa kwahlala kuphezulu, kodwa ngokuvamile, ukuvikelwa okuphelele kwesistimu yokupholisa etshwaleni obunolaka lwamakhemikhali, i-ethylene glycol, kwehla.

Lesi sinqumo asihambisani nabanye abakhiqizi bezimoto. Ngempela, esimweni se-G12 antifreeze, kwakudingeka ukunikeza umkhawulo omkhulu wokuphepha ohlelweni lokupholisa noma ukubekezelela insiza yayo ewayo.

Ngakho-ke, ngemva nje kokukhululwa kwe-G12 antifreeze, umkhiqizo obuyekeziwe wangena ezimakethe: G12 +. Kulesi sipholile, ngaphezu kwezithasiselo ze-carboxylate, izithasiselo ze-inorganic zengezwe ngamanani amancane. Zakha ungqimba oluncane oluvikelayo phezu kwendawo yonke yesistimu yokupholisa, kodwa empeleni azizange zinciphise ukushuba kokudlulisa ukushisa. Futhi uma kwenzeka umonakalo kule filimu, ama-carboxylate compounds aqala ukudlala futhi alungisa indawo eyonakele.

Ingabe ama-antifreeze e-G12+ ne-G12 angaxutshwa?

Ukuxuba ama-antifreeze ngokuvamile kuhilela ukwengeza uhlobo olulodwa lwesinqamuleli kolunye. Ngokushintshwa okuphelele, ngokuvamile akekho oxuba izinsalela zamathini ahlukahlukene. Ngakho-ke, sicabangela izimo ezimbili zokuxuba.

1. Ithangi ekuqaleni yayine-G12 antifreeze, futhi udinga ukwengeza i-G12 +. Kulokhu, ungakwazi ukuxuba ngokuphepha. Izipholile zeClass G12+, ngokomthetho, zisebenza emhlabeni wonke futhi zingaxutshwa nanoma iyiphi enye i-antifreeze (ngaphandle kokungavamile). Izinga lokushisa lokusebenza kwenjini ngeke likhuphuke, izinga lokubhujiswa kwezakhi zesistimu ngeke likhuphuke. Izithasiselo ngeke zisebenzisane nganoma iyiphi indlela, ngeke zinemvula. Futhi, impilo yesevisi ye-antifreeze izohlala ifana, njengoba yomibili le mikhiqizo, ngokwezinga, inesikhawu phakathi kokushintshwa kweminyaka engu-5.

2. Ekuqaleni ibikuhlelo lwe-G12 +, futhi udinga ukugcwalisa i-G12. Lokhu kushintsha nakho kuvunyelwe. Okuwukuphela komphumela ongase ube khona ukuvikela okuncishisiwe kancane kwezindawo zangaphakathi zesistimu ngenxa yokuntuleka kwezakhi ze-inorganic kuphakheji yokwengeza. Lezi zinguquko ezingezinhle zizoba zincane kangangokuthi ngokuvamile zinganakwa.

Abakhiqizi bezimoto kwesinye isikhathi babhala ukuthi akunakwenzeka ukwengeza i-G12 ku-G12 +. Kodwa-ke, lokhu kungaphezu kwesilinganiso somshwalense oweqile kunesidingo esiphusile. Uma udinga ukugcwalisa uhlelo, kodwa azikho ezinye izinketho, zizwe ukhululekile ukuxuba noma iyiphi i-antifreeze yeklasi ye-G12, kungakhathaliseki ukuthi yimuphi umenzi kanye ne-subclass. Kodwa ngesinye isikhathi, ngemva kwezingxube ezinjalo, kungcono ukuvuselela ngokuphelele i-antifreeze ohlelweni futhi ugcwalise isipholile esidingwa yimithethonqubo.

Iyiphi i-antifreeze ongayikhetha, nokuthi iholela kuphi.
