远洋渔船船体严重腐蚀的原因及防护

On the Cause of Serious Corrosion of Pelagic Fishing Ship and How to Protect against It

因油漆性能不佳，牺牲阳极使用寿命不足，电解质温度、浓度和流速较高，导致远洋渔船船体严重腐蚀，应使用乙烯系或氯化橡胶系船底防锈漆，正确设计使用牺牲阳极。

Using the paint not up to the standard, giving up the possitive pole in inadequate service life and the high temperature, concentration of the electrolyte as well as current velocity of the sea water result in serious corrosion of the pelagic fishing ship. It might be possible to protect against the serious corrosion of the pelagic fishing ship of the untirust paint of ethylene system and chloride rubber system should be used for the ship bottom and to give up the possitive pole in service life should be correctly designed for protection of the negative pole.
