2nd, coating sample to be measured is taken, using clean hard plastic sheet as ground, above-mentioned silica gel frame is mould, and sample is made.
It is required that without obvious air pocket inside coating, surface is smooth, otherwise sample preparation again.Same procedure prepares three samples.
3rd, maintain second day, sample is stripped；Maintain the 4th day, closed sample frame with rosin paraffin.
4th, the model prepared is put into 23 ± 2 DEG C, maintained 7 ± 1 days in 50 ± 5% environment.
5th, the test of permeability resistance
5.1st, chromophoric solution is injected into measure device, then immerses sample in nitrite ion, liquid level is that sample is thick
2/3 or so of degree；
5.2nd, sample is taken out from nitrite ion after 1 hour, sample is splitted from centre, observation sample be colored height from
And judge the permeability resistance of sample.
Cut sample need to only to delineate with cutter in the middle of the face of being unstained, then broken into two with one's hands along delineation vestige.Then root
It is colored height to judge the permeability resistance of sample according to sample in cross section.
Applicating example：
The situation that seeped water behind 1 hour of three samples is as shown in the table：
From upper table it can be seen that, the height that three samples A, B, C are colored be respectively in, low, height, then its permeability
Power be exactly respectively in, it is strong, weak.
Largely tested by inventor, the actual permeability resistance of sample of this experiment is consistent with result of the test.
Therefore, the above results represent that permeability can distinguish the permeability resistance ability of different materials well.
