The anti-freeze fluid is characterized by long effect and environmental protection, and can perform all-aroundmulti-layer protection on an automobile cooling system.
Description
Technical field
The present invention relates to a kind of deicing fluid system that automobile cooling system is carried out multilayer protection in all directions, be meant a kind of deicing fluid especially.
Background technology
Deicing fluid is a kind of liquid of low freezing point; can not freeze at low temperatures; has good flowability; can take away a large amount of heat that produces in the engine operation process; it is the heat-eliminating medium of automobile water-cooling formula engine; be used for radiator in winter anti-boiling in antifreeze, summer, and can prevent effectively that cooling system fouling, metallic element from corroding, protect normal working of engine.The popularity rate of developed country's automobile antifreeze solution has reached 100%, and domestic only have about 5%, and still does main heat-eliminating medium with water.
Deicing fluid is divided into inorganic type and organic type two classes, domestic use mostly be low-grade inorganic type deicing fluid, when engine operation 25000～50000km, need replenish corrosion inhibitor or change deicing fluid.But because this class additive low-cost silicate, borax prescriptions of using, the deicing fluid poor stability in use is easy to generate precipitation and separates out and cause cooling system failure more.And organic acid type deicing fluid prescription is all expensive, and its application only limits to a spot of high-grade car.
Summary of the invention
The technical problem that the present invention mainly solves is: a kind of deicing fluid is provided.
In order to address the above problem, technical scheme of the present invention is: by mass percentage, comprise following component:
