Attachment 1:
1.Test Conditions
Test temperature: 25 ° C
Test medium type: standard foaming liquid (GB/T 26527-2011)
Test medium addition: 150ml
Defoamer use method: Direct addition of antifoam stock solution
Defoamer added amount: 0.2g
2.Testing method:
Take 100g of standard foaming liquid in 250ml sample bottle, heat it to the test temperature in water bath, then add the specified amount of defoamer; place the sample bottle on the vertical oscillator; set the parameters: frequency is 450rpm/min, amplitude is 30mm; respectively oscillate the plastic bottle for different time; After each oscillation stop, record the time t' of' the foam disappeared to see most of the liquid surface, and the foam volume after the shaking of the blank standard solution was recorded as V.
3.Elimination and suppression rate calculation method
The ratio of the foam volume V formed by vertically oscillating the blank foaming liquid to the defoaming time t' of each oscillation after the addition of the antifoaming agent. The data of vertical oscillation for 1 min is recorded as the defoaming rate, and the data of vertical oscillation for 5 min is the foam suppression rate.
ŋ=v/t';
v -Foam volume;
t'-Defoaming time after defoamer addition.
