1. Test process:


1. Install and test three sets in three different rooms;


2, the first installed in the large room, about 8 to 9, installed the filter on the curtain, tested twice, no alarm in
 the process, no leakage;


3, the second installation in a small room, a total of 1, installed the filter after direct test, no alarm in the
 middle, alarm around; Cloth curtain, still alarm, through the search, found that there is a large gap between 
the box and the ceiling, through multiple sealant, until the gap is repaired, the final test without alarm, no 
leakage. In the process, it was found that as long as the glue is not in place, there is a little gap, it may alarm;




4, the third installed in a small room, a total of 1, installed on the box first glue seal, and then test, test results: 
no alarm in the middle, alarm around; The curtain on the cloth is tested again, the first time there is a point an
 alarm, go back to the past and test again, no alarm; After two tests, the results did not appear alarm.


In this process, we also measured the depth of the jelly glue filled by the liquid tank, the jelly glue depth of 17~
18mm, the box knife edge of 15mm, so the jelly glue can completely drown the knife edge of the box, there is 
no possibility of jelly glue leakage.


2. Problem summary:


Based on the above, the following conclusions can be made:


1. The box gradually falls during the use of the box, resulting in gaps leading to leaks;


2, measures: this situation needs to glue leakage;


3, there is a lot of dust on the removed filter, in the process of disassembly and handling, the dust on the old 
filter pollutes the environment of the clean room; At the same time, if in this process, the air supply pipeline 
continues to supply air without the installation of the new filter, the dust in the pipeline will enter the clean 
room. The above two situations will lead to a serious decline in the cleanliness of the clean room.


4, measures: First remove all the old filters immediately bagged or packed to reduce secondary pollution; Then
 install the new filter, and then ventilation operation, self-cleaning 24 hours later, and then cleanliness test, 
basically can avoid the emergence of alarm problems. It should be noted that before installing a new filter, 
check the box first to see if there is a gap leak, if there is a gap, be sure to glue the leak.


The final result needs to be ventilated and self-cleaning for 24 hours after all filters are installed and leaks are 
repaired, and then judged by the test situation.
