Development, human lives and social environment generate significant damage.According to statistics, loss of the whole world every year caused by corrosion is up to
1000000000000 dollars, various countries due to annual economical losses caused by corrosion failure account for national economy total output value then 2%~
4%, corrosion control level is different because of the different economic development level in various countries.According to《Chinese Investigation On Corrosion report》Data, I
The year corrosion economic loss of state in recent years is about 500,000,000,000 yuan, and this loss is huge.Except corrosion economy problems it
Outside, corrosion process and result are actually also the significant wastage to limited resources on the earth and the energy, to the serious of natural environment
Pollution, the great interference lived to normal production and people, and people are brought with very important social safety sex chromosome mosaicism.
Etching problem can also turn into the important restriction factor for hindering hi-tech development and national sustained economic development.It is estimated that generation
20% metal material is there are about in boundary can not reclaim because being corroded, thus to cause the world each for corrosion of metal and protection question
The most attention of state.
The method for preventing pipe corrosion is a lot, such as paint coatings anti-corrosion, from corrosion resisting alloy, plating, cathodic protection, heat
Zinc immersion and metal thermal spraying etc., wherein most widely used is paint coatings anti-corrosion.Compared with other method, paint coatings are prevented
Corruption is most effective, most economical, using most common method.The complexity but existing many paint coatings are constructed in anti-corrosion, is prepared
Paint coatings tedious process, cost are high, pollute the environment during preparation, and paint coatings corrosion resistance is inadequate, researches and develops a kind of anti-corrosion
