I-Antifreeze G11 kunye ne-G12: yintoni umehluko? Impawu zobugcisa ze-antifreeze G11 ne-G12

I-Antifreeze ibizwa ngokuba yi-cooling liquid, esetyenziswa kwiinkqubo zokupholisa imoto. Ngomlinganiselo wepesenti we-G11 kunye no-G12 utywala, umxholo we-ethylene glycol ngu-90%, izithako-ukusuka ku-5 ukuya kuma-7%, kunye namanzi-ukusuka ku-3 ukuya ku-5%. Abaninzi abakwaziyo ukuba i-antifreeze G11 kunye ne-G12 yiyiphi, umehluko phakathi kwabo, kunye nokuba ingaxutywa. Namhlanje siya kuzama ukuphendula yonke le mibuzo.

Kulolu hlobo lwamanzi G11

I-Antifreezes ebizwa nge-G11 yisisombululo se-silicates enezithako ezingekhoyo. Ukuphuza izixhobo zamanzi eklasini kusetyenzisiwe kwangaphambili kwaye ngoku kusetyenziswa iimoto eziye zaveliswa ngaphambi kowe-1996. Esi siqhelo esivamile. Ingongoma yokubilisa kwesi sixazululo ngama-degrees angama-105, kwaye umphefumlo we-shelf kulezi zipholiyo ziyiminyaka engama-2-3 okanye iikhilomitha eziyi-80,000. Ezi ziqulunqwe zenzelwe ezo zixhobo zeemoto apho umthamo wesimo sokupholisa ukhulu kakhulu. Iifomati zeTosol kwiprogram esebenzisa ifilimu ekhethekileyo yokukhusela, eyenza ukugcina iingxenye kwiinkqubo zokubola. Kodwa ngenxa yale filimu, ukuqhuba ukushisa kunzima kakhulu. Oku kuyimpendulo enzulu, engakhokelela ekugqithiseni. Kwiimoto zanamhlanje, apho umthamo wendlela yokupholisa incinci, i-G11 fluids ayiyi kusebenza. Oku kunokuchazwa ngokulula ngecandelo lokuqhuba i-thermal, elingafaniyo ne-G-antifreeze. Iimpawu zayo ziphantsi kakhulu kunamanye amanxube anamhlanje. Ngokuqhelekileyo iziqulatho ze-G11 zinokubaluleka ngokuluhlaza okanye okwesibhakabhaka. Uluhlu olunjalo lufanelekile kwiimoto ezindala ezineenkqubo zokupholisa umthamo omkhulu. Kufuneka kukhunjulwe ukuba i-radial radiators G11 inobungozi. IziHlomelo azikwazi ukukhusela ngokuqinisekileyo isinyithi kumaqondo aphezulu.

Iimpawu zotywala zeglasi G12

Abaninzi basebenzise imoto yabo i-antifreeze G11, okanye i-antifreeze nje. Aba bantu bayazibuza ngeempawu, kwaye kukho umehluko phakathi kwe-antifreeze kunye ne-antifreeze G12. Ukuphuza ukutywala kwezi klasi kuyahluke ngohlobo olusekelwe kwizinto ze-carboxylate eziphilayo kunye namaqumrhu. Umehluko omkhulu phakathi kwe-antifreeze G11 kunye ne-G12 yindlela yokusebenzisa izithako ezahlukeneyo. I-G12 inendawo ephezulu yokubilisa. Ziyi-115-120 degrees.

Ngokubhekiselele kwimimiselo yokusebenza, abavelisi bhengeza ukuba loo mveliso ayikwazi ukulahlekelwa iipropati zayo iminyaka emi-5. Ngenxa yoko, abaninzi abantu basebenzisa i- antifreeze G12. Iimpawu zayo zobugcisa ziphezulu kakhulu. Kwakhona, umahluko phakathi kwe-G12 kukuba yenzelwe imoto apho injini yenzelwe ukubuyisela phezulu. Iziqu zeli klasi zinomgangatho ophezulu wokuqhuba. Le mixube ithintela kuphela i-foci ekhethekileyo yokubola, kodwa ungayigqubuthela yonke inkqubo ngeefilimu ezikhuselekileyo. Oku kwandisa kakhulu ukusebenza. Kodwa ukuba imoto indala, ingazaliswa nge-antifreeze G11 ne-G12. Uwuphi umehluko phakathi kwabo? Njengoko sele sithethile, yonke into yongeziweyo.

Ukubunjwa kwe-antifreeze G12

Olu gxininiso luqulethe i-90% ye-ethylene glycol ye-diatomic, ngenxa yokuba i-liquid ayifaki. Kwakhona, i-concentrate iqulethe malunga ne-5% yamanzi adibeneyo. Ukongeza, idayi iyasetyenziswa. Umbala uvumela ukuba ufumanise iklasi epholile, kodwa kunokungabikho. Ubuncinane ubuncinane ama-5% ekubunjweni.

I-ethylene glycol ngokwayo ibukrokra kwiinsimbi ezingenayo. Ngoko ke, ukubunjwa kufuneka kufake i-phosphate kunye ne-carboxylate additives. Zisekelwe kwi-acid acids ezonakalisa zonke iziphumo ezimbi. I-Antifreezes enezongezo zingasebenza ngeendlela ezahlukeneyo, kwaye uhlobo lwazo oluphambili yiendlela zokulwa nokubola.

Impawu zobugcisa bokubunjwa kweG12

Yisilwanyana esihambelanayo kunye esicacileyo. Akukho mveliso engcolileyo kuyo, kwaye umbala wayo ubomvu okanye upinki. Ezi ziselo zifakwe kwiqondo lokushisa malunga ne -50 degrees, ubilise kwi-+118. Ukuba siphendula umbuzo malunga nokuba yi-antifreeze G11 kunye ne-G12 yintoni, yintoni umehluko, sinokuthi la mayeza ahluke kwiqondo lokushisa.

Ngokuphathelele iimpawu, zixhomekeke kwingxube ye-ethylene glycol okanye ipropylene glycol kwisisombululo. Ngokuqhelekileyo utywala awukho ngaphezu kwama-50-60%. Oku kuvumela ukufumana iimpawu zokusebenza eziphezulu.

Ukuhambelana kweentlobo ezimbini zokupholisa

Ukuhambelana kwe-antifreeze G11 kunye ne-G12 kukhuthaza iingcinga zabathandi bemoto entsha. Baqala ngeemoto ezisetyenzisiweyo kwaye abazi ukuba zithini kwi-tank yokwandiswa ngumnikazi wangaphambili. Ukuba ufuna kuphela ukwengeza encinci yokupholisa, ngoko kufuneka ukwazi ngokuchanekileyo oko kuthululwa kwinkqubo okwangoku. Ngaphandle koko, kukho ingozi enkulu yokulimaza kakhulu i-SOD, kwaye kungekhona kuphela kuyo, kodwa kwi-injini. Abanini bemoto abanolwazi bancomela ukuba mhlawumbi bangabinakudityanisela yonke into ebanzi kwaye bazalise entsha.

Ukuhambelana nombala

Umbala wamanzi awuchaphazeli iimpawu kunye neempawu. Abavelisi bangapenda iimveliso zabo ngemibala eyahlukileyo, kodwa kukho imigangatho ethile. Iingoma ezithandwa kakhulu zipeyinti eluhlaza, eluhlaza okomvu, obomvu, obomvu, kunye nolunxwemeni. Eminye imilinganiselo iqulethe i-liquids yamatye athile. Kodwa apha umbala we-coolant yi-criterion yakutshanje, ekufuneka ithathelwe ingqalelo.

Ngokuqhelekileyo ukuluhlaza kuthetha ukukhusela i-G11. "Lukoil" kunye nabanye abavelisi bakhiqiza iimveliso ezinjalo. Kukholelwa ukuba ukuluhlaza kukubakala eliphantsi kweG11 okanye umkhiqizo we-silicate.

Ukuhambelana klasi

I-G11 ayixutywanga kunye nemikhiqizo yeklasi G12. Kule meko, oku kwangoko kutshabalalisa zonke iipropati zayo ezizodwa. Kwakhona, baya kulahleka ngokukhawuleza ukuba u-G11 uphakamisa. I-crust, eyenziwe yi-antifreeze, iyaphazamisa kakhulu umsebenzi weG12 epheleleyo. Ukugqithiswa kwamanzi kwi-modern liquid cooling kule meko ayinakunceda ngokupheleleyo. Kodwa apha ngeG13, G12 kunye ne-G12 + i-antifreeze iyahambelana. Kufuneka kukhunjulwe ngabo bonke abaqhubi beemoto. Ngokubhekiselele kwi-G12, idibanisa kakuhle kunye notywala beklasi yeG12 +. Nangona kunjalo, kukho i-G11 i-compounds of a variety of manufacturers, ekufuneka kube nenyameko. Kwakukho iimeko xa izithako kunye neenkalo zenye iklasi zithandana ngokukhawuleza komnye nomnye, ngenxa yezinto ezingaphakathi kwemida ye-ODS imoto yayiyi-jelly yangempela.

Malunga nokukhethwa kwe-antifreeze

Xa ukhetha ukulungelelanisa imoto yakho kufuneka ungagxininisi kumbala kunye neklasi yomkhiqizo. Funda okubhaliweyo kwithanki yokwandisa okanye kwimimiselo emotweni (leyo umenzi ocebisayo). Ukuba i-radiator yenziwa ngeensimbi ezingenabumba - ubhedu okanye ubhedu, ngoko ke imixube ye-organic ayifanelekanga. Inkqubo inokugquma. Kukho iintlobo ezimbini ze-OC - zijoliswe okanye zihlanjululwe ngumenzi. Kubonakala ngathi akukho mmahluko omkhulu phakathi kwezi zibini. Abaninzi batusa ukuthenga ingqalelo kwaye ngokuzimeleyo bawunciphise ngamanzi acwecwe. Ukuba ngaba i-antifreeze yangempela G12, ukuphononongwa kukucetyiswa ukuxuba kwi-1 ukuya ku-1. Ungathengi okokuqala ukupholisa. Kwimveliso, amanzi angcono asetyenziswa. Ihlambulukile kwinqanaba lee-molecule. Ukubunjwa kwemakethe ehlanjululwayo akukhuthazi nabani na ukuba bathembele. Kwiimoto kunye nee-radiators ezivela kwiimbonci ezingezona zinyumba kunye nebhokisi leesilinda ezenziwe ngentsimbi ephosiweyo, kukulungele ukuzalisa i-tosol eluhlaza okwesibhakabhaka okanye eluhlaza. Iimpawu zeramitha zeruminium kunye neenjini zamandla zanamhlanje, i-G12 kunye ne-G12 + - obomvu okanye i-orange - zifanelekile.

Isishwankathelo

Ngoko, ngoku kuyacaca ukuba akuyimfuneko ukuxuba i-antifreeze G11 ne-G12. Uthini umahluko phakathi kwabo, esele sazi. Njengoko uyakubona, ulwahluko oluphambili kwizaziso. Kwimeko yokuqala, i-organic and inorganic isetyenzisiweyo, kwimeko yesibili kuphela izakhi zokugqibela ezisetyenziswayo. Kwakhona iqela le-12 linomsebenzi wobanzi obanzi. Kodwa kuyafaneleka ukuphawula elinye iqela - ngomhla we-13. Kubonakala nje nje kutshanje. Olu hlobo luhluke ngokukodwa kuzo zonke ezidlulileyo kwaye lufumanisa ukufumaneka kwezinto ezinobungqongileyo kuphela. Umbala wale nyi-antifreeze ibomvu. E-Russia, akunqabile, ngokungafani nemakethi yaseYurophu. Iindleko zayo zihlandlo eziliqela ngaphaya kwexabiso le- antifreeze ebomvu eqhelekileyo ukusuka kwiqela le-12. Iipropati, ngokuphantse akavumelani, ngoko kuyacaca ukusebenzisa i-cooler i-G12.
