生锈不但有损于钢构件的美观,而且还会影响它的强度和缩短使用寿命。为此,人们不得不重新给构件刷上漆,耗费大量的人力和物力。 对构件重新刷漆,首先要铲除构件上的锈。可是铲锈极其费工,其费用几乎占整个油漆工程费用的35％。于是,各国都在研制、开发可直接涂于锈面上的涂料。 Rusted steel not only detrimental to the appearance of steel, but also affect its strength and shorten the service life. To this end, people have to re-paint brush components, consuming a lot of manpower and material resources. To re-paint components, we must first eradicate the rust on the components. But shoveling is extremely labor-intensive, the cost of which accounts for almost 35% of the cost of the entire paint project. Thus, all countries are developing and developing coatings that can be applied directly to the rust surface.
