Uyini umehluko phakathi kwe-antifreeze ne-antifreeze? Yini engcono? Ingabe zingaxutshwa?

Lapho sithenga imoto, sifuna ihlale isikhathi eside ngangokunokwenzeka. Impilo yesevisi incike ngokuyinhloko ezimweni zokusebenza kanye nekhwalithi yesevisi.

Uketshezi lwezobuchwepheshe luthinta kakhulu izinga lokusebenza kwazo zonke izinhlelo zenjini. Akuyona indima yokugcina edlalwa uhlelo lokupholisa, ngenxa yokuthi injini igcina izinga lokushisa elifunekayo.

Uma ngaphambili, ekuqaleni kwemboni yezimoto, izinjini zemoto zazenziwe ngensimbi nethusi, khona-ke amanzi ajwayelekile angama-distilled angathululelwa kuma-radiators. Futhi ebusika, i-ethylene glycol noma utshwala kwanezelwa kula manzi ukuze iqhwa lingakheki kurediyetha. Nokho, ezimotweni zanamuhla, ingxube enjalo izofana nokufa, ngoba izovusa izinqubo zokugqwala ngaphakathi kwenjini. Ngakho-ke, osokhemisi baqala ukufuna uketshezi olwalungeke luholele ekugqwaleni kwensimbi.

Yile ndlela i-antifreeze yezimoto eyasungulwa ngayo. Izifundo ezifanayo zenziwa eSoviet Union, lapho ngawo-70s bakwazi ukuthola ifomula yabo ye-antifreeze - Tosol.

Kulokhu singafinyelela iziphetho ezilandelayo:

• i-antifreeze ne-antifreeze iwuketshezi olungaqini emazingeni okushisa aphansi;
• i-antifreeze - leli gama lisetshenziswa emhlabeni wonke;
• I-antifreeze ingumkhiqizo waseRussia ohloselwe izimoto ezikhiqizwa e-USSR naseRussia yesimanje.

Umehluko omkhulu ekubunjweni kwamakhemikhali

Umehluko obaluleke kakhulu ukuthi yiziphi izinto ezifakwe ku-antifreeze ne-antifreeze.

I-antifreeze iqukethe izakhi eziyinhloko eziyisisekelo - amanzi kanye ne-anti-freeze additive ethylene glycol. Amanzi asetshenziselwa ukuletha lokhu kwakheka kwamakhemikhali kuzo zonke izakhi zenjini; i-ethylene glycol ivimbela amanzi ekubeni aqine emazingeni okushisa aphansi. Iqukethe nosawoti we-inorganic acid. - ama-phosphates, ama-nitrate, ama-silicates, aklanyelwe ukuvikela insimbi ekugqwaleni. Ikilasi le-antifreeze lincike ekutheni yimaphi ama-salts e-asidi asetshenziswayo nokuthi yimaphi amaphesenti ezithasiselo ze-antifreeze - okungukuthi, umkhawulo ophansi wokushisa wokuqandisa.

I-antifreeze nayo yenziwe ngamanzi ne-ethylene glycol. I-Glycerin ne-alcohol yobuchwepheshe nayo yengezwa kuyo (yingakho awukwazi ukuphuza i-antifreeze). Kodwa umehluko obaluleke kakhulu ukuthi awekho usawoti wezinto ezingaphili ku-antifreeze; usawoti eziphilayookuthuthukisa kakhulu ukusebenza kwayo.

Isimiso sokusebenza

Njengoba noma iyiphi insimbi yesaba ukuthintana namanzi, kokubili i-antifreeze ne-antifreeze yakha ungqimba oluncane oluyisivikelo ebusweni bezakhi zensimbi zenjini kanye nesistimu yokupholisa evimbela ukuthintana phakathi kwamanzi nensimbi. Nokho, kukhona umehluko kulokhu.

I-antifreeze izungeza ohlelweni bese yenza ifilimu elincanyana eliwuhhafu wemilimitha eliwugqinsi kuzo zonke izindawo zensimbi zangaphakathi. Ngenxa yale filimu, ukudluliswa kokushisa kuphazamiseka, ngokulandelana, injini idinga uphethiloli owengeziwe. Lesi ngesinye sezizathu zokuthi kungani ukusetshenziswa kukaphethiloli kunyuke ebusika, sesivele sithinte lesi sihloko ku-autoportal yethu iVodi.su.

Ukuba khona kosawoti we-silicate kanye ne-nitrite kuholela eqinisweni lokuthi bayakhuphuka, kwakhiwa i-slurry efana ne-gel, evala kancane kancane amangqamuzana e-radiator.

I-Antifreeze idinga ukushintshwa kaningi - njalo ngamakhilomitha ayizinkulungwane ezingu-40-50, ayikwazi ukuhlala isikhathi eside, ngoba ifilimu yokuzivikela ibhujiswa ngaphansi kwethonya lokushisa eliphezulu futhi injini isongelwa ukugqwala. I-Antifreeze iqala ukubilisa emazingeni okushisa angaphezu kuka-105-110 degrees.

I-Antifreeze isebenza ngesimiso esifanayo, kodwa umehluko wokuthi ifilimu evikelayo ibonakala kuphela kulezo zakhi ezikwazi ukugqwala, ngokulandelana, ukusetshenziswa kukaphethiloli kwalabo bashayeli abathululela i-antifreeze akukhuphuki kakhulu. Futhi, i-antifreeze ayinikezi imvula enjalo, ayidingi ukushintshwa kaningi, uketshezi alulahlekelwa izakhiwo zalo ngokugijima kwamakhilomitha angaphezu kwezinkulungwane ezingama-200. Uma ubilisa, i-antifreeze ayenzi igwebu nama-flakes avala i-radiator. Yebo, futhi ibilisa ekushiseni kwama-degree angu-115.

Okusho ukuthi, siyabona ukuthi uma ukhetha phakathi kwe-antifreeze ne-antifreeze, khona-ke ukukhetha kufanele kunikezwe ekugcineni.

Kodwa into enjalo njengoba intengo idlala ngokumelene naye - i-canister ye-antifreeze engu-5-litre ibiza i-penny, kuyilapho amanani abalulekile kufanele akhokhelwe i-antifreeze.

Yiqiniso, kunezinkohliso eziningi kule makethe: uma ubona imibhalo enjengokuthi "Antifreeze-Silicate", noma "Antifreeze-Tosol", bese ubuza umeluleki umehluko omkhulu phakathi kwe-antifreeze ne-antifreeze - usawoti we-organic kanye ne-inorganic acid.

Ama-silicates ayiqembu elibanzi lamaminerali angenakuhlotshaniswa nakancane nezinto eziphilayo, okungukuthi, azama ukukuthengisela i-antifreeze ngaphansi kwe-antifreeze.

Khumbula futhi ukuthi i-antifreeze ayidingi ukuhlanjululwa ngamanzi a-distilled. Izinga lokushisa layo elibandayo livame ukuba esifundeni ukusuka ku-15 ukuya ku-minus 24-36 degrees. I-Antifreeze, ngakolunye uhlangothi, ingathengiswa kokubili ngesimo sengxube esenziwe ngomumo nangendlela yokugxila. Uma uthenga i-antifreeze egxilile, khona-ke kufanele ihlanjululwe ngesilinganiso esisodwa kuya kwesinye, lapho indawo yokuqandisa izoba -40 degrees.

I-Antifreeze ayinconywa ukuthenga izimoto ezenziwe kwamanye amazwe. Isibonelo, iToyota ithela i-antifreeze ebomvu.

Ungaxuba kuphela i-antifreeze yombala ofanayo, noma kunjalo uma kufanele uhlanganise i-antifreeze ne-antifreeze. Ngaphambi kokwengeza i-antifreeze, zonke izinsalela zangaphambilini kufanele zikhishwe.

Ukuze umshini uhlale isikhathi eside ngangokunokwenzeka ngaphandle kokuqhekeka, thenga kuphela izinhlobo ze-antifreeze noma i-antifreeze enconywe umenzi.
