Performance evaluation：
1. foaming agent performance measurement method
Foaming agent performance test is used in volume as in the elongated cylindrical transparent glass container of 500mL, accurate to add
Foaming agent 10mL, then adds 20mL distilled water, gently shakes up again, records original expanding foam solution volume at this time, then carries out acute
Strong vibration, until foam volume no longer changes, makes expanding foam solution in container fully foam completely, record foam volume is foaming body
Product.Calculate the ratio between foam volume and original expanding foam solution volume, i.e. coefficient of foaming, the mark using this data as foaming agent foam ability
Will.Will foaming cylinder in foam be statically placed in natural environment, used in naturally stand environment under foam volume with the time reduction situation
Represent the stability of foam, work as foam volume<During 200mL, own defoaming is considered as.
