Gxila noma esenziwe ngomumo i-antifreeze. Yini engcono?
Okuqukethwe
Iquketheni i-antifreeze concentrate futhi ihluke kanjani kumkhiqizo oqediwe?
I-antifreeze evamile elungele ukusetshenziswa iqukethe izingxenye ezi-4 eziyinhloko:
- i-ethylene glycol;
- amanzi agcobhoziwe;
- iphakheji elengeziwe;
- udayi.
I-concentrate ishoda eyodwa kuphela yezingxenye: amanzi acwecwe. Izingxenye ezisele ekubunjweni okuphelele ziyizinguqulo ezigxilile zokupholisa. Ngezinye izikhathi abakhiqizi, ukuze benze lula futhi bavimbele imibuzo engadingekile, bamane babhale "Glycol" noma "Ethandiol" emaphaketheni, okuyinto, eqinisweni, elinye igama le-ethylene glycol. Izithasiselo kanye nodayi ngokuvamile akukhulunywa.
Kodwa-ke, ezimweni eziningi, zonke izingxenye ezingeziwe kanye nodayi zikhona kukho konke ukwakhiwa okukhiqizwa abakhiqizi abazihloniphayo. Futhi lapho amanzi engezwa ngesilinganiso esifanele, okukhiphayo kuzoba yi-antifreeze evamile. Namuhla emakethe kukhona ikakhulukazi i-antifreezes G11 ne-G12 (kanye nokuphuma kwayo, i-G12 + ne-G12 ++). I-antifreeze ye-G13 ithengiswa isilungile.
Esigabeni esishibhile, ungathola futhi i-ethylene glycol ejwayelekile, engacetshisiwe ngezithasiselo. Kufanele isetshenziswe ngokuqapha, ngoba lobu tshwala ngokwawo bunobudlova obuncane bamakhemikhali. Futhi ukungabikho kwezithasiselo ezivikelayo ngeke kuvimbele ukwakheka kwesikhungo sokugqwala noma kumise ukusabalala kwayo. Okuthi ngokuhamba kwesikhathi kuzonciphisa impilo ye-radiator namapayipi, kanye nokwandisa inani lama-oxide akhiwe.
Iyiphi i-antifreeze engcono noma i-antifreeze concentrate?
Ngenhla, sithole ukuthi mayelana nokwakheka kwamakhemikhali ngemuva kokulungiswa kokugxilisa ingqondo, ngeke kube khona umehluko ngomkhiqizo ophelile. Lokhu kunombandela wokuthi izilinganiso zizobhekwa.
Manje cabangela izinzuzo zokugxilisa ingqondo phezu kokwakheka okuqediwe.
- Amathuba okulungiselela i-antifreeze enephuzu lokuqandisa elifaneleka kahle isimo. Ama-antifreeze ajwayelekile alinganiselwe ngokuyinhloko ku -25, -40 noma -60 °C. Uma uzilungiselela ngokwakho i-coolant, ungakhetha ukugxila endaweni lapho imoto isebenza khona. Futhi kunephuzu elilodwa elicashile lapha: ukuphakama kokumelana nezinga lokushisa eliphansi kwe-ethylene glycol antifreezes, kunciphisa ukumelana nokubila. Isibonelo, uma i-antifreeze enephuzu lokuthululela lika--60 ° C ithululelwa esifundeni esiseningizimu, izobilisa lapho ishisa endaweni ku-+120 ° C. Umkhawulo onjalo wama-motor "ashisayo" anokushayela okujulile utholakala kalula. Futhi ngokudlala ngesilinganiso, ungakhetha isilinganiso esifanele se-ethylene glycol namanzi. Futhi okokupholisa okubangelwayo ngeke kuqine ebusika futhi kuzomelana namazinga okushisa aphezulu ehlobo.
- Ulwazi olunembile mayelana nokuthi i-antifreeze concentrate ehlanjululwe izoba yiqhwa kuliphi izinga lokushisa.
- Amathuba wokwengeza amanzi a-distilled noma ukugxila ohlelweni ukuze ushintshe indawo yokuthela.
- Mancane amathuba okuthi uthenge inkohliso. Ama-concentrates ngokuvamile akhiqizwa izinkampani ezivelele. Futhi ukuhlaziya okukha phezulu kwemakethe kuphakamisa ukuthi kukhona ama-fake amaningi phakathi kwama-antifreeze enziwe ngomumo.
Phakathi kokubi kokuzilungiselela kwe-antifreeze kusuka ku-concentrate, umuntu angabona isidingo sokufuna amanzi a-distilled (kunconywa kakhulu ukuthi ungasebenzisi amanzi ampompi ajwayelekile) kanye nesikhathi esichithwa ekulungiseni umkhiqizo ophelile.
Ngokusekelwe kulokhu osekushiwo ngaphambili, akunakwenzeka ukusho ngokungananazi ukuthi yikuphi okungcono, i-antifreeze noma ukugxila kwayo. Ukwakheka ngakunye kunezinzuzo zayo kanye nokubi. Futhi lapho ukhetha, kufanele uqhubeke kokuncamelayo.
