Izici ze-Antifreeze A-40
Izici
Njengamanye ama-coolants wokwakheka okufanayo (isibonelo, i-antifreeze A-65), i-A-40 ihlanganisa, ngaphezu kwe-ethylene glycol, izithasiselo ezihlukahlukene:
- I-Antifoam.
- Ukuvimbela izinqubo zokugqwala.
- Umbala (udayi oluhlaza uvame ukusetshenziswa kakhulu, kodwa i-Tosol A-40 ebomvu nayo ingatholakala endalini).
Ezikhathini zaseSoviet, lapho umkhiqizo uhlanganiswa okokuqala, akekho owayehilelekile ekubhaliseni igama, ngakho-ke, ezitolo ezikhethekile zesimanje, ungathola inani elanele lemikhiqizo efanayo ekhiqizwa abakhiqizi abahlukene.
Izici zomzimba ze-antifreeze, ezihambisana ngokugcwele nezidingo zobuchwepheshe ze-GOST 28084-89 kanye ne-TU 2422-022-51140047-00, zimi kanje:
- I-Crystallization iqala izinga lokushisa, ºC, hhayi ngaphansi: -40.
- ukuzinza kwe-thermal, ºC, hhayi ngaphansi: +120.
- Ukuminyana, kg/m3 -1100.
- inkomba ye-pH - 8,5 .... 9,5.
- Umthamo wokushisa ngu-0ºC, kJ/kg K - 3,19.
Iningi lezinkomba ezichazweyo zinqunywa ukuhlushwa kwe-ethylene glycol ekubunjweni kwe-Tosol A-40, i-viscosity yayo kanye nokushisa okubalulekile kwe-coolant, ebekwe ngesikhathi sokusebenza kwenjini. Ikakhulukazi, i-viscosity eguquguqukayo yomkhiqizo isukela ku-9 cSt ku-0ºC, kufika ku-100 cSt at -40ºC. Ngokwebanga lokushisa elinikeziwe, kungenzeka ukusungula ikhwalithi ye-antifreeze ethengiwe.
Ungahlola kanjani ikhwalithi ye-Antifreeze A-40?
Kubanikazi bezimoto, ukuhlolwa kokufaneleka kokupholisa kulula kakhulu ukukwenza kulawa maphuzu alandelayo:
- Isilinganiso sokuminyana: uma sihluka kakhulu kunani elijwayelekile, siba sibi kakhulu. Ubuningi obuncishisiwe bubonisa ukuthi umkhiqizo uqukethe i-ethylene glycol, ehlanjululwe ngokweqile ngamanzi.
- Ngokunquma i-alkalinity yangempela ye-pH yesisombululo: kumanani ayo aphansi, izakhiwo zokulwa nokubola kokubunjwa ziwohloka kakhulu. Lokhu kubi kakhulu ezingxenyeni zenjini ezenziwe nge-aluminium.
- Ngokusho kokufana nokuqina kombala: uma ukukhanya okuluhlaza okwesibhakabhaka, noma, ngokuphambene, kumnyama kakhulu, khona-ke ukwakheka kungenzeka ukuthi kwenziwa kudala, futhi kulahlekelwe izimfanelo zayo eziningi eziwusizo.
- Hlola i-crystallization emazingeni okushisa aphansi. Uma i-Tosol A-40 ingashintshi ivolumu yayo lapho iqhwa ngaphandle komoya, khona-ke unomkhiqizo omuhle wekhwalithi;
- Ukuhlolwa kokuzinza kwe-thermal, lapho inani elithile lokupholisa lilethwa ngamathumba, emva kwalokho lishiywe ukubilisa phezu kokushisa okuphansi imizuzu eminingana. Ngesikhathi esifanayo, iphunga elibukhali le-ammonia akufanele lizwakale, futhi uketshezi ku-flask luhlala lusobala, ngaphandle kokukhulula imvula phansi.
Zonke lezi zivivinyo ezingenhla zingenziwa ngaphandle kokuthengwa kwezinsimbi ezikhethekile.
izindleko
Ngenani le-Antifreeze brand A-40 noma i-A-40M, awukwazi ukusungula ukwethembeka komkhiqizi kuphela, kodwa futhi nekhwalithi yokupholisa. Abakhiqizi abakhulu bapakisha i-antifreeze ezitsheni zamakhono ahlukahlukene futhi bakhiqize umkhiqizo ngamaqoqo amakhulu. Ngakho-ke, intengo ingase ibe ngaphansi kancane kunesilinganiso (kodwa hhayi ngokuningi!). Ngokungahleliwe, amafemu angewona akhethekile ngaphansi kwegama lomkhiqizo elithi "Tosol A-40" angakhiqiza umgunyathi ojwayelekile - i-ethylene glycol ehlanjululwe ngamanzi (noma eshibhile kodwa i-methylene glycol enobuthi kakhulu), lapho kufakwa inani elithile lokudla odayi abaluhlaza okwesibhakabhaka. Intengo ye-pseudotosol enjalo izoba ngaphansi kakhulu.
Ngokuya ngohlobo lwesiqukathi, abakhiqizi nezifunda zokuthengisa, intengo ye-Antifreeze A-40 iyahlukahluka ngaphakathi kwemikhawulo elandelayo:
- Ezitsheni 5 l - 360 ... 370 ruble.
- Ezitsheni 10 l - 700 ... 750 ruble.
- Ezitsheni 20 l - 1400 ... 1500 ruble.
Uma upakisha emiphongolweni yensimbi engu-220 l, amanani omkhiqizo aqala kuma-ruble angu-15000.
