Abstract
PURPOSE: To obtain a water dispersion type antifrothing agent that dispalys self- emulsification performance that the compounded components do not show mutually and independently and improves the dispersion force of the sntifrothing agent to a surface of a foaming liquid, by compounding two kinds of polyoxyalkylenepolyol type antifrothing agents, which are water-unsoluble at normal temp.
CONSTITUTION: This antifrothing agent is produced by compounding compounds in an expression I (For example, a compound produced in such a manner that molecular wt. is made to be 4500 by adding prolylene oxide to glycerin and total molecular wt. is made to be 5000 by further adding EO) and compounds in an expression II (For example, a compound manufactured in such a manner that molecular wt. is made to be 3000 by adding propylene oxide to propylene glycol) at wt. ratio of 95:5W50:50 - especially, 80:20W60:40. Components, such as, pigment, a coloring agent, etc. can be mixed to the antifrothing agent as necessary. The antifrothing agent may be added to a foaming liquid as it is, and generally used in the dilution of approx. 50W1000ppm.
