Ndinogona kusanganisa mavara akasiyana eantifreeze?

Ko ruvara rwe antifreeze rwunobva kupi?

Iyo inotonhodza inobatsira kuona kuti mota yekutonhodza system inoshanda nemazvo panguva yechando. Inoda kuchinjwa nguva nenguva. Uye ipapo pane mubvunzo wekusarudza. Pakutengeswa kune mvura yemhando dzakasiyana uye dzakasiyana dzeEuropean, American, Asia uye Russian vagadziri. Kunyange mutyairi ane ruzivo haagoni nguva dzose kutaura nechokwadi kuti vakasiyana sei uye kana imwe kana imwe mhando yakakodzera motokari yake. Iwo mavara akasiyana-siyana ezvinotonhorera - bhuruu, girini, yero, tsvuku, yepepuru - ari kunyanya kuvhiringa.

Nheyo yeantifreeze inowanzova musanganiswa wemvura yakasvibiswa uye ethylene glycol. Chiyero chavo chakananga chinotarisa nzvimbo yechando yechando.

Mukuwedzera, kuumbwa kunosanganisira zvakasiyana-siyana zvinowedzera - anti-corrosion (corrosion inhibitors), anti-foam nevamwe.

Zvose izvi zvikamu hazvina ruvara. Nokudaro, mumamiriro ayo echisikigo, inenge yese antifreeze, pamwe chete nekuwedzera, imvura isina ruvara. Ruvara runopiwa kwairi nedhayi dzakachengeteka dzinobatsira kusiyanisa antifreeze kubva kune zvimwe zvinwiwa (mvura, peturu).

Mitemo yakasiyana-siyana haitungamiri ruvara rwakasiyana, asi kurudzira kuti ruve rwakajeka, rwakakwana. Kana mvura ikabuda, izvi zvichabatsira kuona kuti dambudziko riri mumotokari inotonhorera.

Zvishoma nezve mwero

Nyika zhinji dzine mipimo yadzo yenyika. Vagadziri vakasiyana vanewo yavo yakasarudzika yeantifreeze. Iyo inonyanya kuzivikanwa classification yakagadzirwa neVolkswagen kunetseka.

Maererano nazvo, ese antifreezes akakamurwa muzvikamu zvishanu:

G11 - inogadzirwa pahwaro hwe ethylene glycol uchishandisa tsika (silicate) tekinoroji. Sezvo anti-corrosion additives, silicates, phosphates uye zvimwe zvinhu zvisingasviki zvinoshandiswa pano, izvo zvinogadzira chidziviriro chekudzivirira mukati memukati wegadziriro yekutonhora. Nekudaro, iyi layer inoderedza kutamisa kupisa uye inoputsika nekufamba kwenguva. Kunyange zvakadaro, mvura yakadaro inogona kushandiswa, asi usakanganwa kuishandura makore maviri ose.

Kirasi iyi yakagoverwa ruvara rwedhayi yebhuruu-girinhi.

Volkswagen inosanganisirawo inonzi hybrid antifreezes mukirasi ino, iyo inogona kuiswa muyero, orenji uye mamwe mavara.

G12, G12+ - carboxylates inoshandiswa pano se corrosion inhibitors. Antifreezes akadaro akasununguka kubva pakuipa kwesilicone tekinoroji uye anogara kubva pamakore matatu kusvika mashanu.

Muvara wedhayi wakatsvuka, zvishoma kazhinji zvepepuru.

G12 ++ - antifreezes akagadzirwa uchishandisa bipolar tekinoroji. Zvinoitika kuti vanonzi lobrid (kubva kuChirungu low-hybrid - low-hybrid). Kuwedzera kune carboxylates, shoma shoma yesilicon makomisheni inowedzerwa kune zvinowedzera, izvo zvinowedzera kuchengetedza aluminium alloys. Vamwe vagadziri vanoti hupenyu hwesevhisi hwemakore gumi kana kupfuura. Asi nyanzvi dzinokurudzira kutsiva makore ese mashanu.

Rudzi rwakatsvuka kana ruvara rwepepuru.

G13 - Rudzi rutsva rwekutonhorera rwakaonekwa makore mazhinji apfuura. Chepfu ethylene glycol yakatsiviwa pano nepropylene glycol, iyo isinganyanyi kukuvadza vanhu uye zvakatipoteredza. Zviwedzerwa zvakafanana neG12 ++.

Dhayi yeyero kana yeorange inowanzoshandiswa sechiratidzo chemavara.

Izvo zvinofanirwa kutakurwa mupfungwa kuti havasi vese vanogadzira veEurope vanoomerera kune iyi kupatsanurwa, tisingarevi maAsia neRussia.

Mythology

Kushaikwa kwemaitiro epasirese epasirese kwakakonzera kuwanda kwengano dzinoparadzirwa kwete chete nevatyairiwo zvavo, asiwo nevashandi vemotokari nevashandi vekutengesa mota. Ngano idzi dziri kutendererawo paInternet.

Zvimwe zvacho zvinongoenderana nemuvara we antifreeze. Vanhu vazhinji vanofunga kuti ruvara rweinotonhorera inoratidza kunaka uye kusimba. Vamwe vanodavira kuti antifreeze dzose dzeruvara rumwe chete dzinochinjika uye dzinogona kusanganiswa.

Kutaura zvazviri, ruvara rwezvinotonhorera haruna chokuita nekushanda kwayo. Kazhinji, antifreeze imwechete inogona kupendwa nemavara akasiyana, zvichienderana nezvido zvemutengi waanopihwa.    

Chii chekufunga kana uchitenga

Paunenge uchitenga antifreeze, kutarisisa kushoma kunofanirwa kubhadharwa kune ruvara rwayo. Sarudza chinotonhorera zvichienderana nekurudziro yemugadziri wemotokari yako.

Pamota yega yega, iwe unofanirwa kusarudza yako wega mhando yekutonhodza, uchifunga nezve hunhu hwekutonhora system uye mukati memoto injini. Izvo zvakakosha kuti iyo antifreeze ive yemhando yakakwana uye inoenderana nehutongi hwekushisa kweinjini yako yekupisa yemukati.

Mukurumbira wemugadziri une basawo. Tenga zvigadzirwa kubva kumhando dzinozivikanwa pese pazvinogoneka. Kana zvisina kudaro, kune ngozi yekumhanya mune yakaderera-yemhando chigadzirwa, umo, semuenzaniso, musanganiswa we glycerin uye methanol inoshandiswa panzvimbo ye ethylene glycol. Mvura yakadaro ine viscosity yakakwirira, nzvimbo yakaderera yekubikira uye, uyezve, inotyisa zvikuru. Kushandiswa kwaro kuchakonzera, kunyanya, kuwedzera kuonda uye pakupedzisira kukuvadza pombi uye radiator.

Chii chekuwedzera uye kana zvichibvira kusanganisa

Usakanganwa kuchengeta ziso pazinga re antifreeze. Kana iwe uchida kuwedzera zvishoma zvemvura, zviri nani kushandisa mvura yakasvibiswa, iyo isingazodzikisi kunaka kweantifreeze zvachose.

Kana, semugumisiro wekudonha, iyo inotonhorera yakadzika zvakanyanya, saka antifreeze yemhando imwechete, mhando uye mugadziri anofanira kuwedzerwa. Chete munyaya iyi kusavapo kwezvinetso kunovimbiswa.

Kana zvisinganyatsozivikanwi kuti chii chinodururwa muhurongwa, saka zvakanakisisa kutsiva mvura yacho zvachose, uye kwete kuwedzera izvo zvaive pedyo. Izvi zvinokununura kubva kumatambudziko anogona kusaonekwa nekukurumidza.

Mune antifreezes, kunyange yemhando imwechete, asi kubva kune vakasiyana vanogadzira, akasiyana ekuwedzera mapakeji anogona kushandiswa. Havasi vese vanowirirana uye kazhinji kudyidzana kwavo kunogona kukonzera kuderedzwa kweinotonhorera, kuderera kwekutamisa kupisa uye kudzivirira anti-corrosion zvivakwa. Mumamiriro ezvinhu akaipisisa, izvi zvinogona kutungamirira kukuparadzwa kwegadziriro yekutonhora, kupisa kwejini inopisa mukati, nezvimwewo.

Paunenge uchisanganisa antifreezes, hapana mhosva iwe unofanirwa kutungamirirwa nemuvara, sezvo ruvara rwemvura haritauri zvachose pamusoro pezvinowedzera zvinoshandiswa. Kusanganisa antifreezes emavara akasiyana kunogona kupa mhedzisiro inogamuchirwa, uye zvinwiwa zveruvara rumwe chete zvinogona kusapindirana zvachose.

G11 uye G12 antifreezes hazvienderane uye hazvifanirwe kusanganiswa nemumwe.

G11 uye G12+ inotonhorera inowirirana, pamwe neG12++ neG13. Kuenderana kunoreva mukana wekushandiswa kwenguva pfupi kwemisanganiswa yakadai pasina mhedzisiro yakakomba kana antifreeze inokurudzirwa isipo. Mune ramangwana, kutsiva kwakakwana kwemvura mune inotonhorera system kunofanirwa kuitwa.

Musanganiswa wemhando yemvura G13 ine antifreeze G11, G12 uye G12 + inogamuchirwa, asi nekuda kwekuderedzwa kweanti-corrosion properties, zviri nani kusaishandisa.

Kuti uongorore kuenderana usati wasanganisa, unofanirwa kudururira imwe mvura kubva mumotokari inotonhorera muchirongo chakajeka uye wowedzera antifreeze pairi. Kana pasina shanduko yekuona yakaitika, saka zvinwiwa zvakadaro zvinogona kutariswa zvinoenderana nemamiriro ezvinhu. Turbidity kana kunaya kwemvura kunoratidza kuti zvikamu zvezvinowedzera zvakapinda mumakemikari reaction. Musanganiswa uyu haufanirwe kushandiswa.

Zvinofanira kuyeukwa kuti kusanganisa antifreezes akasiyana chiyero chekumanikidza uye chenguva pfupi. Sarudzo yakachengeteka ndeyekutsiva zvachose chinotonhorera nekunyatso kupuruzira system.
