Performance   evaluation

1.1   Foam break experiment

(1)   Take 100ml 0.5% 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.

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 0.5% 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;
