Performance evaluation

1.1   Foam break experiment

(1)   Take 100ml 0.1% foaming solution into 1000ml measuring cylinder, then open   

air pump to bubble to 1000ml and turn off air pump;

(2)   Take 100 ul defoamer into measuring cylinder and record time of foam elimination.   

1.2   Antifoaming experiment

(1)   Operate as foam break experiment;

(2)   After foam disappearing, bubble once more, record the time the foam increases up 

 to 1000ml;

(3)   Operate (2) repeatedly and take the average time.  

Scoring   standard of foam break: 5 point,<30s is 5 point; 30-60s is 4 point; 60-90s is 3 point1.5-3   mins is 2 point; 3-5 minutes is 1 pointother time is 0 point;

Foaming agent preparation:

Take 1g foaming agent into 1000ml breaker, then add water to dilute and 

prepare foaming agent solution with 1% active content; Stir10 min and then

add water to dilute as 0.1% solution for reservation.


Operation proposal

1.      Add in each stage in production of water-based products;

2.      Do not dilute defoamers to avoid influencing defoaming property;

3.      If   defoamer appears freezing or layering, it should be melted or mix 

         even at   first;

4.      After adding defoamer, it should be stirred completely to make sure 

         good dispersion of defoamer;

5.      Suggested dosage is 0.2-1%;

6.      Advise gradient test;
