What is
the difference between Acetylenic Glycol surfactant and Traditional
surfactants?
1.Charge factor
|
|
Lonic surfactant: Charge stabilized foam.
VS
Acetylenic glycol: Non-ionic surfactants don’t require charge stabilization factors
2.Surface viscosity
Lonic surfactant:The higher surface viscosity is the more stable the bubble.
Acetylenic glycol: The hydrophilic group is arranged horizontally, and the internal cohesion is small; the surface viscosity is small, and the foam stability is reduced.
3.Steric hindrance
Traditional surfactants: have large molecular weight and large steric hindrance, which prevents microbubbles from continuing to combine into large bubbles and break them.
Acetylenic glycol:The space is small, and microbubbles are easily combined into large bubbles to enhance defoaming ability.
