Indlela yokunciphisa ukugxila kwe-antifreeze?
Iyini i-antifreeze concentrate?
I-antifreeze egxilile iqukethe ingxenye eyodwa kuphela engekho: amanzi acwecwe. Zonke ezinye izakhi (i-ethylene glycol, izithasiselo kanye nombala) ngokuvamile zikhona ngokugcwele.
Ukugxilisa okupholile kuvame ukudideka ngephutha ne-ethylene glycol emsulwa. Abanye abakhiqizi babonisa emaphaketheni ukuthi kukhona i-ethylene glycol kuphela ngaphakathi. Nokho, lokhu akukwazi ukuba yiqiniso ngenxa nje yokuthi i-ethylene glycol iwuketshezi olungenambala. Futhi cishe wonke ama-concentrates anemibala ngokusho kokumaka okujwayelekile kwekilasi (G11 - eluhlaza, G12 - obomvu noma ophuzi, njll.).
Ngaphambilini, ama-concentrate apholile angenambala ayethengiswa. Kungenzeka ukuthi basebenzisa i-ethylene glycol ehlanzekile. Kodwa-ke, akuthandeki ukusebenzisa i-concentrate enjalo ekulungiseleleni i-coolant yezinga eliphezulu. Ngempela, ngaphandle kwezithasiselo, ukugqwala kwensimbi kanye nokucekelwa phansi kwamapayipi enjoloba kuzosheshisa kakhulu. Futhi lezi zingoma bezifaneleka kuphela ukuthuthukisa izakhiwo ezisezingeni eliphansi ze-antifreeze esele ithululiwe.
Ubuchwepheshe bokuzalanisa kanye nezilinganiso
Okokuqala, ake sithole ukuthi singaxuba kanjani i-concentrate namanzi ukuze ungadingi ukuthulula ukwakheka okuwumphumela kamuva.
- Ukulandelana kwalokho okumele uthele kukho akunandaba. Kanye nesitsha okuzoxutshwa kuso. Kubalulekile nje ukugcina izilinganiso.
- Thela amanzi ethangini lokunweba kuqala, bese ugxilisa ingqondo, kwezinye izimo kungenzeka, kodwa engathandeki. Okokuqala, uma ulungiselela i-antifreeze ngokushesha ukuze uthole indawo ephelele, khona-ke inani olibalile lingase linganele. Noma, ngokuphambene, uthola i-antifreeze eningi kakhulu. Isibonelo, uqale uthele ama-3 amalitha okugxila, bese uhlela ukwengeza amalitha amathathu amanzi. Ngoba babazi ukuthi umthamo ophelele wokupholisa uhlelo ungamalitha ayi-3. Kodwa-ke, amalitha ama-6 e-concentrate alingana ngaphandle kwezinkinga, futhi kwangena amalitha angu-3 kuphela amanzi. Ngoba kwakusekhona i-antifreeze endala ohlelweni, noma kukhona i-radiator engeyona evamile, noma kunesinye isizathu. Futhi ebusika, emazingeni okushisa angaphansi kuka-2,5 ° C, kwenqatshelwe ngokuphelele ukugcwalisa uketshezi ngokwehlukana. Kuyaxaka, kodwa kuyiqiniso: i-ethylene glycol ehlanzekile (kanye ne-antifreeze concentrate) ibanda ku -13 ° C.
- Ungafaki ukugxilisa ingqondo kusuka kokupholisa okukodwa kuya kwesinye. Kunezimo lapho, ngesikhathi sokuxuba okunjalo, ezinye izithasiselo zingqubuzana futhi ziwa.
Kunezilinganiso ezintathu ezivamile zokuxuba ezipholile:
- 1 kuya ku-1 - i-antifreeze enephuzu lokuqandisa cishe -35 ° C itholakala endaweni yokuphuma;
- 40% concentrate, 60% amanzi - uthola isibandisi esingaqini sifike ku -25 ° C;
- 60% concentrate, 40% amanzi - antifreeze ezomelana namazinga okushisa ehle aze afike ku-55 ° C.
Ukuze udale i-antifreeze namanye amaphuzu okuqandisa, kunethebula elingezansi elibonisa uhla olubanzi lwezingxube ezingaba khona.
| Gxilisa okuqukethwe kungxube, % | Iphuzu lokuqandisa le-antifreeze, ° C |
| 100 | -12 |
| 95 | -22 |
| 90 | -29 |
| 80 | -48 |
