Antifreezes

Antifreeze most often call automobile cooling liquid as temperature of its freezing is lower than water freezing temperature. Antifreeze is intended for prevention of the damage of details caused by expansion of water at its freezing. Antifreezes not only have lower temperature of freezing (more precisely — a point of the beginning of loss of a crystal phase), but also when freezing form the kasheobrazny weight which formation does not damage an engine detail, though does not allow the engine to work normally. Therefore temperature of freezing is the important operational characteristic of antifreeze. Automobile antifreezes consist of ethylene glycol, water and a package of the additives giving to antifreeze anticorrosive, anti-cavitational, antifoam and fluorescent properties. Ethylene glycol besides fall of temperature of freezing leads to temperature increase of boiling of cooling liquid that is an additional benefit at operation of cars in a warm season. Add the dyes giving to antifreeze this or that color to antifreezes. Color of antifreeze has no relation to its operational properties and is a subject of the arrangement of the producer and consumer. Often same antifreeze is painted in different colors for different consumers. Now antifreezes on composition of anticorrosive additives are divided into karboksilatny, hybrid and traditional types
