Isa pfungwa kana yakagadzirira-yakagadzirwa antifreeze. Chii chiri nani?
Zviri mukati
Chii chinonzi antifreeze concentrate chinosanganisira uye chinosiyana sei kubva pane chakapedzwa chigadzirwa?
Iyo yakajairwa-yekushandisa-yekushandisa-antifreeze ine zvikamu zvina zvikuru:
- ethylene glycol;
- mvura yakadzika;
- additive package;
- dhayi.
Iyo concentrate inoshaikwa imwe chete yezvikamu: distilled mvura. Izvo zvakasara zvikamu mukuumbwa kwakazara zviri mune yakaomeswa shanduro dzezvinotonhorera. Dzimwe nguva vanogadzira, kuitira kuti zvive nyore uye kudzivirira mibvunzo isingakoshi, ingonyora "Glycol" kana "Ethandiol" pakuputira, iyo, chaizvoizvo, ndiro rimwe zita re ethylene glycol. Zvinowedzerwa uye dhayi hazviwanzo kutaurwa.
Zvisinei, muhuwandu hwakawanda hwezviitiko, zvose zvinowedzera zvikamu uye dhayi zviripo mune zvose zvakagadzirirwa zvinogadzirwa nevanozviremekedza vanozvikudza. Uye kana mvura yawedzerwa muchikamu chakakodzera, inobuda ichave yakajairwa antifreeze. Nhasi pamusika pane kunyanya kuisa antifreezes G11 uye G12 (uye zvinobva zvayo, G12 + uye G12 ++). G13 antifreeze inotengeswa yakagadzirira-yakagadzirwa.
Muchikamu chakachipa, iwe unogona zvakare kuwana yakajairwa ethylene glycol, isina kupfumiswa nezvinowedzerwa. Inofanira kushandiswa nekuchenjerera, sezvo doro iri pacharo rine kemikari zvishoma. Uye kusavapo kwezvidziviriro zvinowedzera hazvizodzivisi kuumbwa kwenzvimbo yekuora kana kumisa kupararira kwayo. Izvo mukufamba kwenguva zvichaderedza hupenyu hwe radiator uye mapaipi, pamwe nekuwedzera kuwanda kwemaokisi akaumbwa.
Chii chiri nani antifreeze kana antifreeze concentrate?
Pamusoro, takaona kuti maererano nekuumbwa kwemakemikari mushure mekugadzirwa kweiyo concentrate, panenge pasisina misiyano nechigadzirwa chakapedzwa. Izvi zvine mamiriro ekuti zviyero zvichacherechedzwa.
Iye zvino funga zvakanakira iyo concentrate pane yakapedzwa kuumbwa.
- Iko mukana wekugadzirira antifreeze nenzvimbo inotonhora inonyatso kuenderana nemamiriro ezvinhu. Standard antifreezes inonyanya kurongerwa -25, -40 kana -60 °C. Kana iwe ukagadzirira iyo inotonhorera iwe pachako, saka iwe unogona kusarudza iyo yekumisikidza chete yenzvimbo iyo motokari inoshandiswa. Uye pane imwe pfungwa yakavanzika pano: iyo yakakwirira kuderera-kupisa kupikisa kwe ethylene glycol antifreezes, kuderera kwekudzivirira kuvira. Semuenzaniso, kana antifreeze ine nzvimbo yekudirwa ye -60 ° C yakadururirwa kunharaunda yekumaodzanyemba, inozovira kana ichipisa munzvimbo kusvika + 120 ° C. Chikumbaridzo chakadaro che "hot" motors ine yakanyanya kutyaira inowanikwa nyore. Uye nekutamba nechikamu, unogona kusarudza iyo yakakwana chiyero che ethylene glycol nemvura. Uye iyo inotonhorera inokonzeresa haizoomese munguva yechando uye ichave ichipokana nekupisa kwakanyanya muzhizha.
- Ruzivo rwakakwana nezve tembiricha yakaderedzwa antifreeze concentrate inotonhora.
- Kugona kuwedzera mvura yakasvibiswa kana kuisa pfungwa kune sisitimu yekuchinja nzvimbo yekudira.
- Kashoma kutenga fake. Concentrates inowanzogadzirwa nemakambani ane mukurumbira. Uye kuongororwa kwepamusoro kwemusika kunoratidza kuti kune mamwe fake pakati peakagadzirira-akagadzirwa antifreeze.
Pakati pezvakashata zvekuzvigadzirira-yega antifreeze kubva kune concentrate, munhu anogona kuona kukosha kwekutsvaga mvura yakasvibiswa (inokurudzirwa zvakanyanya kusashandisa yakajairika mvura yemupombi) uye nguva inoshandiswa pakugadzira chigadzirwa chakapedzwa.
Kubva pane zvataurwa, hazvibviri kutaura zvisina mubvunzo kuti ndezvipi zviri nani, antifreeze kana kuisa pfungwa kwayo. Imwe neimwe yakagadzirwa ine zvayakanakira nezvayakaipira. Uye pakusarudza, iwe unofanirwa kuenderera kubva pane zvaunoda.
