Glycol eitiléine: Is féidir leis an gcomhpháirt sreabhach bonn is coitianta, le feidhmíocht fhrith -fhréamh maith, an reophointe uisce a ísliú go héifeachtach, ionas nach reoitear an chuisneoir ag teochtaí ísle .
Glycol próipiléine: cosúil le glycol eitiléine, is comhpháirt sreabhach bonn antifreeze a úsáidtear go coitianta é freisin, ar féidir leis an reophointe . a ísliú i gcomparáid le glycol eitiléine, tá glycol próipiléine níos lú tocsaineach agus níos cairdiúla don chomhshaol, agus is minic a úsáidtear é in ócáidí le ceanglais ard sábháilteachta {{}}}}}}}}} {}}} {}}} {}} {}} {}} {} {} {} {} {} {} {} {} {} {} {} {} {} go minic i gceanglais ard -sábháilteachta {}

In order to prevent antifreeze from corroding the metal parts of the cooling system, corrosion inhibitors such as organic amines, phosphates and phosphates are added. They can form a protective film on the metal surface to prevent the metal from contacting the acidic substances or other corrosive components in the antifreeze, thereby extending the service life of metal parts such as copper, iron, and aluminum in the engine and córas fuaraithe .

During the storage and use of antifreeze, microorganisms are easily bred, causing mold and deterioration, affecting its performance. Therefore, a small amount of bactericidal and antifungal agents, such as sodium benzoate, are added to inhibit the growth of microorganisms and ensure that the antifreeze does not mold during the 2-3 year storage tréimhse .

During the circulation of the cooling system, bubbles are easily generated due to the flow and stirring of the liquid. Bubbles will affect the heat transfer efficiency and cooling effect of the coolant, and may even cause cavitation and damage the cooling system components. Antifoaming agents can reduce the surface tension of the liquid, causing bubbles to burst quickly and ensure the normal operation den chuisneoir .

D'fhonn breathnóireacht an leibhéil chuisnithe agus an sceitheadh ​​a éascú, agus chun é a idirdhealú ó leachtanna eile, is iondúil go gcuirtear datháin le sreabhán frith -fhrith -fhrith -fhrith -fhrith -fhrith -fhrith -fhrith -ghlas -25 chun dath sonrach a chur i láthair, mar shampla glas, gorm, dearg, srl. .
