Abstract:
     This invention is a kind of additive for circulative cooling water of internal combustion engine, which has functions of anti-cavitation erosion, anti-electric-chemical corrosion and scale reducing. The characteristics of this additive are rich in resources, low cost and noside-effect since it is made from polyacrytic ester, sodium benzoate, sodium tetraborate and other additional materials. It can prevent lubricating parts of cooling system from cavitation damage and electri-chemical corrosion effectively, and reduce scale, keep internal system clear. It is best to be used for the cooling system which has intensive, potential cavitation damage in cylinder slceve.
