Description
Technical field
The present invention relates to defoaming agent field, specially a kind of high effective antifoaming agent, meanwhile, the invention further relates to one kind efficiently to disappear
The preparation method of infusion.
Background technique
Defoaming agent is the lower substance of a kind of surface tension, can be rapidly on vacuolar membrane surface after defoaming agent and vacuolar membrane contact
It sprawls, for defoaming agent molecule instead of blistering agent molecule original on foam surface, the new liquid film of formation is inhomogenous due to surface
Property it is stronger, cause new Film strength very low, foam stability decline, be readily broken.Meanwhile defoaming agent is gone back in the process of cleaning
Stronger foam-inhibiting effect need to be embodied, since defoaming agent has a stronger surface-active compared with infusion, lower surface tension, preferentially
It being adsorbed on the vacuolar membrane liquid film of air liquid interface, defoaming agent own face inhomogeneity is stronger, and it is poor to be formed by vacuolar membrane elasticity,
So the unstability of foam is higher, foam-inhibiting effect is produced.Also solubility size is related in water to defoaming agent for foam-inhibiting effect:
General only to play disposable defoaming for the defoaming agent big for solubility, after defoaming agent is dissolved, defoaming effect may
It completely disappears, foam can regenerate again；The small or insoluble defoaming agent of solubility is after first time brokenly bubble, still with insoluble
State be present in bubbling system, at this moment defoaming agent not only can inhibition system generate foam, and can to the foam of generation rise
To defoaming effect again.
Defoaming agent is probably divided into containing silicon defoaming agent, fluorine-containing defoaming agent, polyether antifoam agent etc. by composition difference.Containing silicon defoaming agent
Defoaming effect is good, but can form silicon spot in metal surface after use, is not suitable for using in metal degreasing agent；Fluorine-containing defoaming agent disappears
Bubble, foam inhibition effect are good, but cost is excessively high, there is certain corrosivity to metal surface；Polyether antifoam agent defoaming effect is not as good as preceding two
Class, but it is with excellent antifoaming ability, and on cleaning effect without influence, therefore, is largely applied in metal degreasing agent.
Less toxic, anti-oxidant, the brokenly bubble ability that existing defoaming agent has is strong, but its foam inhibition ability is lower, thus consumption is big.
Although some defoaming agent foam inhibition abilities are strong, stability is poor.
