Iyini i-G12 antifreeze - umehluko kusuka ku-G11, G12 +, G13 nokuthi iyiphi okudingeka igcwaliswe

I-antifreeze iyadingeka ukupholisa injini yemoto. Namuhla, ama-coolants ahlukaniswa ngezinhlobo ezi-4, ngayinye ehluka ngezithasiselo nezinye izakhiwo. Wonke ama-antifreeze owabona emashalofini esitolo akhiwe ngamanzi ne-ethylene glycol, futhi yilapho ukufana kuphela khona. Ngakho-ke ama-coolants ahluke kanjani komunye nomunye, ngaphezu kombala nezindleko, khetha i-antifreeze efanele yemoto yakho, kungenzeka yini ukuxuba ama-coolants ahlukene bese uwahlanza ngamanzi - qhubeka ufunda.

Yini i-antifreeze?

I-Antifreeze yigama elivamile lesipholisa imoto. Kungakhathaliseki ukuthi i-propylene glycol noma i-ethylene glycol ikhona ekubunjweni kwe-antifreeze, kanye nephakheji layo lezithasiselo. 

I-Ethylene glycol iyi-alcohol ye-dihydric enobuthi. Ngendlela ehlanzekile, iwuketshezi olunamafutha, inambitheka emnandi, iphuzu layo elibilisa lingaba ama-degree angu-200, futhi iphuzu layo lokuqandisa liyi--12,5 °. Khumbula ukuthi i-ethylene glycol ingushevu oyingozi, futhi umthamo obulalayo womuntu ungama-300. amagremu. Ngendlela, ubuthi bunqanyuliwe nge-ethyl alcohol.

I-Propylene glycol yigama elisha emhlabeni wezipholile. Ama-antifreezes anjalo asetshenziswa kuzo zonke izimoto zanamuhla, ezinezindinganiso ezinobuthi obuqinile, ngaphezu kwalokho, i-antifreeze esekelwe ku-propylene glycol inezakhiwo ezinhle kakhulu zokugcoba kanye ne-anti-corrosion. Utshwala obunjalo bukhiqizwa kusetshenziswa isigaba sokukhanya se-distillation kawoyela.

Kusetshenziswa kuphi futhi kanjani ama-antifreezes

I-Antifreeze ithole ukusetshenziswa kwayo kuphela emkhakheni wezokuthutha emgwaqeni. Ngokuvamile isetshenziswa ohlelweni lokushisa lwezakhiwo zokuhlala kanye nezakhiwo. Esimweni sethu, umsebenzi oyinhloko we-antifreeze ukugcina izinga lokushisa lokusebenza kwe-injini ngendlela enikeziwe. I-coolant isetshenziswa ejazini elivaliwe lenjini kanye nolayini, iphinde idlule endaweni yabagibeli, ngenxa yokuthi umoya ofudumele uvunguza lapho kuvulwa isitofu. Kwezinye izimoto, kukhona isishintshi sokushisa sokudlulisa okuzenzakalelayo, lapho i-antifreeze namafutha ihlangana ngokufana endlini eyodwa, ilawula izinga lokushisa komunye nomunye.

Phambilini bekusetshenziswa isipholisi esibizwa nge- "Tosol" ezimotweni, lapho izidingo eziphambili zikhona:

• ukugcina ukushisa okusebenzayo;
• izakhiwo zokuthambisa.

Lolu olunye uketshezi olushibhile olungasetshenziswa ezimotweni zesimanje. Sekuklanyelwe ama-antifreezes amaningi kubo: G11, G12, G12 + (++) no-G13.

I-Antifreeze G11

I-Antifreeze G11 ikhiqizwa endaweni eyisisekelo ye-silicate, iqukethe iphakethe lezithasiselo ezingaphili. Lolu hlobo lokupholisa lwalusetshenziselwa izimoto ezazenziwe ngaphambi kuka-1996 (yize ukubekezelelana kwezinye izimoto zesimanje kuze kufike ku-2016 kwenza kube nokwenzeka ukugcwalisa i-G11), ku-CIS kwathiwa yi "Tosol". 

Ngenxa yesisekelo sayo se-silicate, i-G11 yenza le misebenzi elandelayo:

• kwakha ukuvikelwa kwendawo, kuvimbela i-ethylene glycol ukuthi ingabalimazi;
• kubambezela ukusabalala kokugqwala.

Lapho ukhetha i-antifreeze enjalo (umbala wayo uluhlaza okwesibhakabhaka nohlaza okotshani), naka izici ezimbili:

• impilo eshalofini ayidluli iminyaka emi-3, kungakhathalekile ibanga. Ngesikhathi sokusebenza, ungqimba oluvikelayo luba mncane, lezi zingcezu, zifike kwisipholisi, ziholele ekugqokeni kwayo okusheshisiwe, kanye nasekulimaleni kwepompo lamanzi;
• ungqimba oluvikelayo alubekezeleli amazinga okushisa aphezulu, ngaphezu kwama-105 degrees, ngakho-ke ukudluliswa kokushisa kwe-G11 kuphansi.

Konke ukungalungi kungagwenywa ngokushintsha ngesikhathi esifanele i-antifreeze nokuvimbela ukushisa kwenjini. 

Futhi khumbula ukuthi i-G11 ayizifanele izimoto ezine-aluminium cylinder block ne-radiator njengoba i-coolant ingakwazi ukuzivikela emazingeni okushisa aphezulu. Qaphela lapho ukhetha abakhiqizi besabelomali, njenge-Euroline noma i-Polarnik, cela ukwenza isivivinyo se-hydrometer, izimo zivame ukuvela lapho i-coolant ebhalwe ukuthi "-40 °" empeleni iba ngu -20 ° nangaphezulu.

 I-Antifreeze G12, G12 + ne-G12 ++

I-antifreeze yomkhiqizo we-G12 ibomvu noma ebomvana. Ayisenawo ama-silicates ekubunjweni kwayo, isekelwe kuma-carboxylate compounds kanye ne-ethylene glycol. Isilinganiso sempilo yesevisi ye-coolant enjalo yiminyaka engu-4-5. Ngenxa yezithako ezikhethiwe kahle, izakhiwo zokulwa nokugqwala zisebenza ngokukhetha - ifilimu idalwe kuphela ezindaweni ezonakaliswe ukugqwala. I-antifreeze ye-G12 isetshenziswa ezinjinini ezinesivinini esikhulu ezinokushisa okusebenzayo okungu-90-110 degrees.

I-G12 inesiphambeko esisodwa kuphela: izakhiwo ezilwa nokugqwala zivela kuphela lapho kukhona ukugqwala.

Imvamisa i-G12 ithengiswa njenge-concentrate enophawu lwe- "-78 °" noma "-80 °", ngakho-ke udinga ukubala inani lesipholisi ohlelweni bese ulihluza ngamanzi acolisisiwe. Isilinganiso samanzi ne-antifreeze sizokhonjiswa kulebula.

Okwe-antifreeze ye-G12: ayihlukile kakhulu kowandulelayo, umbala ubomvu, othuthukisiwe usuphephe kakhulu futhi ulungele imvelo kakhulu. Ukwakheka iqukethe izithasiselo anti-ukugqwala, ukusebenza pointwise.

I-G12 ++: Imvamisa i-purple, inguqulo ethuthukisiwe yama-carboxylated coolants. I-antifreeze ye-Lobride yehlukile kwe-G12 ne-G12 + lapho kukhona izithasiselo ze-silicate, lapho izakhiwo zokulwa nokugqwala zisebenza ngokuqonde ngqo futhi zivimbela ukwakheka kokugqwala.

I-Antifreeze G13

Isigaba esisha se-antifreeze siyatholakala ngombala onsomi. I-antifreeze ye-Hybrid inokwakheka okufanayo, kepha isilinganiso esihle kakhulu sezinto ze-silicate nezinto eziphilayo. Iphinde ibe nezici ezithuthukisiwe zokuvikela. Kunconywa ukuthi ushintshe njalo eminyakeni emihlanu.

I-Antifreeze G11, G12 ne-G13 - uyini umehluko?

Umbuzo uvame ukuvela - kungenzeka yini ukuxuba ama-antifreeze ahlukene? Ukuze wenze lokhu, udinga ukuhlolisisa izici zesipholisi ngasinye ukuze uqonde ukuhambisana.

Umehluko omkhulu phakathi kwe-G11 ne-G12 akuwona umbala, kodwa ukwakheka okubalulekile: eyokuqala inesisekelo se-inorganic/ethylene glycol. Ungayixuba nanoma iyiphi i-antifreeze, into esemqoka ukuthi kukhona ukuhambisana kwekilasi - G11.

Umehluko phakathi kwe-G12 ne-G13 ukuthi owesibili unesisekelo se-propylene glycol, kanti isigaba sokuphepha kwemvelo siphakeme kaningana.

Ngokuxuba okupholisayo:

• I-G11 ayihlangani ne-G12, ungangeza kuphela i-G12 + ne-G13;
• I-G12 iphazamisa i-G12 +.

Imibuzo nezimpendulo:

I-antifreeze isetshenziselwa ini? Iwuketshezi olusebenzayo lwesistimu yokupholisa injini yemoto. Inephuzu eliphezulu lokubilisa futhi yakhiwe ngamanzi nezithasiselo ezigcoba iphampu nezinye izakhi ze-CO.

Kungani i-antifreeze ibizwa kanjalo? I-Anti (against) Iqhwa (iqhwa). Lokhu kuvame ukuba yigama lawo wonke uketshezi olunqanda ukuqhwaza olusetshenziswa ezimotweni. Ngokungafani ne-antifreeze, i-antifreeze inezinga lokushisa eliphansi le-crystallization.

Yimaphi ama-antifreeze akhona? I-Ethylene glycol, i-carboxylate ethylene glycol, i-hybrid ethylene glycol, i-lobrid ethylene glycol, i-propylene glycol. Zibuye zihluke ngombala: obomvu, oluhlaza okwesibhakabhaka, oluhlaza.
