In translation from English "antifreeze" – "nonfreezing". That is, it is cooling liquid for running engines in the conditions of low temperatures. To make antifreeze – means, having applied certain additives, to lower temperature of freezing of cooling liquid.
It is required to you
- Concentrate of antifreeze (OZh-K)
Instruction
1. To lower temperature of freezing of cooling liquid in the cooling system of your car, add to water, for example, alcohol. Or the glycerin which is also promoting fall of temperature at which crystallization of molecules of water begins. But such simplest compositions of nonfreezing cooling liquid cannot solve for today all those problems which face modern antifreezes. Therefore to make antifreeze, get an antifreeze concentrate in shop and prepare, following the enclosed instruction.
2. Modern grades of antifreezes for cars with internal combustion engines are created on the basis of ethylene glycol. Ethylene glycol – the representative of polyatomic alcohols. In the cleaned look – it is flavourless slightly oily colourless transparent liquid. On taste it is sweetish and very toxic. Hit of ethylene glycol in the person can terminate in a lethal outcome.
3. Besides ethylene glycol, additives which give to antifreeze anticorrosion properties are added to water for receiving quality cooling liquid. For this reason leave antifreeze in the cooling system and in warm season. Especially as ethylene glycol increases temperature of boiling of your cooling liquid, and it is important in the conditions of hot summer.
4. Still the important property is gained by cooling liquid thanks to additives – an antikavitatsionnost. Cavitation is a formation and breakage of vials of steam in liquid when boiling. This process gradually destroys metal, cutting from a surface of a microparticle and forming ulcers which easier then are exposed to corrosion. Ulcers expand in sinks. Also additives give to liquid antifoam properties.
