The efficiency in pond is extremely low, this illustrates that each component in each lining produces synergistic effect in entire substrate system, only passes through that
This interaction could effectively enhance its corrosion resistance；Compared by the test result of embodiment 1 and comparative example 7, Ke Yifa
Existing, the corrosion resistance of flexible substrate prepared by the present invention improves a lot compared with similar product.
Table 1
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details.
