Abstract

PURPOSE:To eliminate the danger for inhaling of toxicity, inflammability, etc. owing to org. solvents and eliminate problems of pollution owing to waste water after water washing by removing excess penetrant liquid by the use of powder and granules. CONSTITUTION:Upon ending of pretreatment of an object to be inspected, penetrant liquid is adapted and the object is penetrated with said liquid for 10min, after which powder and granules consisting of glass beads and diatomaceous earth are sprayed onto the excess penetrant liquid. The excess penetrant liquid is sucked up and moved to powder and granule layers by the adsorption effect possessed individually by the powder and granules having wide interfaces and the capillarity created between the powder and granules, and therefore the excess penetrant liquid is removed from the surface of the object to be inspected by removing the powder and granules. Next, a developer is coated on the surface of said object and its defect parts are detected. Thereby, the need for using volatile org. solvents, emulsifiers or water is eliminated at all, and the problems caused by inhalant toxicity, inflammability, waste water, etc. are eliminated.
