Transport box and container can guarantee that institute's freight can not suffer a loss.Such as, wind, rain, snow, hail are met, it is necessary to maintain secrecy
Product be required to transport box and container.Although existing container turns into system substantially, so-called is huge as system
Substantially there is principle type specification in specification.But existing variety of container is various, material is different, because container is needed goods
Transport the whole world, it should with easy handling, protect commercial articles safety, facilitate the characteristics such as privacy of user.
Existing, container surface has fine pore size, and pore and micro-crack are to cause seepage to cause contents to be drenched
Wet basic reason.If capillary porosity duct and micro-crack blocked, it becomes possible to play waterproof, impervious effect, and existing use
In being coated in the coating of container surface in addition to attractive in appearance, also with certain corrosion resistance characteristic, but it is remote with container
Ocean transport and long-time exposure processing, conventional corrosion resistant coating are increasingly difficult to meet demand.
Accordingly, it would be desirable to it is a kind of there is waterproof, it is impervious, solve in the presence of a harsh environment, container surface has crackle and rotten
A kind of corrosion resistant coating for container of erosion problem.
The content of the invention
The present invention can not meet transport by sea and long-time the exposure processing with container for existing common coating, draw
Playing seepage causes the problem of contents are drenched there is provided a kind of corrosion resistant coating for container.
The present invention solves above-mentioned technical problem, and the technical scheme of use is that a kind of corrosion resistant coating for container is applied
