Nzira yekudzikisa sei antifreeze concentrate?
Chii chinonzi antifreeze concentrate?
Concentrated antifreeze ine chikamu chimwe chete chisipo: distilled water. Zvimwe zvese zvinoumba (ethylene glycol, additives and colorant) zvinowanzovapo zvizere.
Inotonhorera inogadzirisa inowanzo vhiringika zvisizvo ne pure ethylene glycol. Vamwe vanogadzira vanoratidza pakurongedza kuti mukati mune ethylene glycol chete. Nekudaro, izvi hazvigone kuve chokwadi nekuti ethylene glycol imvura isina ruvara. Uye zvinenge zvese zvinotariswa zvine mavara zvichienderana neyakagamuchirwa kirasi yekumaka (G11 - girini, G12 - tsvuku kana yero, nezvimwewo).
Kare, michina inotonhorera isina ruvara yaitengeswa. Vangangodaro vakashandisa pure ethylene glycol. Nekudaro, hazvidiwe kushandisa iyo yekuisa pfungwa pakugadzirira kwepamusoro-giredhi inotonhorera. Chokwadi, pasina zvinowedzerwa, simbi corrosion uye kuparadzwa kwepombi dzerabha kuchawedzera zvakanyanya. Uye idzi nziyo dzaive dzakakodzera chete kusimudzira kudzika-tembiricha zvivakwa zveyakatodururwa antifreeze.
Kuberekesa tekinoroji uye zviyero
Kutanga, ngationei chaizvo kuti tingasanganisa sei concentrate nemvura kuitira kuti usazodurura mhedzisiro yacho gare gare.
- Kutevedzana kwezvekudira hazvina basa. Pamwe chete nemudziyo umo kusanganiswa kuchaitika. Zvinongokosha kuchengeta zviyero.
- Dururira mvura mutangi yekuwedzera kutanga, uye ipapo kuisa pfungwa, mune dzimwe nguva zvinogoneka, asi zvisingadiwi. Chekutanga, kana uri kugadzirira antifreeze nekukasira kuti utsive yakakwana, saka mari yawakaverenga inogona kunge isina kukwana. Kana, zvakasiyana, unowana antifreeze yakawandisa. Semuenzaniso, iwe wakatanga kudurura 3 malita ekuisa pfungwa, uye ndokuronga kuwedzera 3 malita emvura. Nekuti vaiziva kuti vhoriyamu yakazara yekutonhodza muhurongwa i6 litres. Zvisinei, 3 malita e-concentrate akakodzera pasina matambudziko, uye chete 2,5 malita emvura akapinda. Nekuti paive pachine antifreeze yekare muhurongwa, kana kune isiri-standard radiator, kana pane chimwe chikonzero. Uye munguva yechando, pane tembiricha iri pasi -13 ° C, zvinorambidzwa zvachose kuzadza zvinwiwa zvakasiyana. Zvinoshamisa, asi ndezvechokwadi: pure ethylene glycol (pamwe neantifreeze concentrate) inotonhora pa -13 ° C.
- Usawedzera concentrate kubva pane imwe inotonhorera kuenda kune imwe. Pane zviitiko apo, panguva yekusanganiswa kwakadaro, zvimwe zvekuwedzera zvakapesana uye zvakanaya.
Kune matatu akajairwa kusanganisa ratios kune inotonhorera:
- 1 kusvika 1 - antifreeze ine chando chinopisa chinenge -35 ° C inowanikwa pakubuda;
- 40% concentrate, 60% mvura - unowana coolant isingaome kusvika kusvika -25 ° C;
- 60% concentrate, 40% mvura - antifreeze inotsungirira tembiricha kusvika -55 ° C.
Kugadzira antifreeze nemamwe mapoinzi echando, pane tafura pazasi inoratidza huwandu hwakakura hwemisanganiswa inogona kuitika.
