Document Type and Number:
Japanese Patent JP2519669
Kind Code:
B2
Abstract:
PURPOSE: To obtain a clogging-preventing agent capable of preventing clogging of liquid sucking wig, enabling life prolongation of the wick by using for suction type heat transpiration device and simultaneously capable of remarkably improving transpiration properties of a chemical by the suction type heat transpiration device.
CONSTITUTION: This clogging preventing agent is obtained by blending 0.05-2.0wt.%, preferably 0.1-1.0wt.% of, at least, one kind of compound selected from among 24 kinds of compounds of (i) 3,5-di-tert. butyl-4-hydroxytoluene, (ii) 3-tert. butyl-4-hydroxyanisol, (iii) mercaptobenzimidazole, (iv) dilauryl-thio-di- propionate, (v) 2,2'-methylene-bis-(6-tert. buthyl-4-methylphenol, (vi) 1,1-bis(4- hydroxyphenyl)cyclohexane, (vii) 1,3,5-trimethyl-2,4,6-tris(3,5-di-tert.-butyl-4- hydroxybenzyl)benzene, (viii) phenyl-β-naphthylamine, (ix) N,N'-diphenyl-p- phenylene diamine, etc., into a chemical liquid composition for liquid sucking wick.
