专利汇可以提供Aerosol type liquid penetrant, aerosol type detergent and aerosol type developer to be used for solvent removable penetrant testing method专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain the results of flaw detection with high accuracy without inducing the destruction of the ozone layer and th environmental pollution problem by a greenhouse effect by mixing one kind of either HCFC 22 or HFC 125 and one or ≥2 kinds of isobutane, n-butane, etc., as an injecting agent.
CONSTITUTION: The prepd. penetrating agent itself is sealed into an aerosol can in accordance with the conventional method by using the mixture composed of 50 to 60wt.% of one kind of either the HCFC 22 or HFC 125 and 40 to 50wt.% one or ≥2 kinds selected from the isobutane, n-butane, HCFC 141b, HCFC 142b, HCFC 123, HCFC 124, and methylene chloride as the injecting agent. The volumetric ratio of the injecting agent and the penetrating agent itself is preferably specified to (1 to 1.1) : 1 and is sealed into the can under 3 to 5kg/cm
2 internal pressure. The penetrating agent itself can be sprayed to the last. The uniform spraying condition and the uniform coated film similar to those of the conventional methods are thus obtd.
