METHOD FOR DIAGNOSIS OF CONDITIONS OF UNIT EQUIPMENT FOR APPLICATION OF THIN COATINGS ONTO MOVABLE FLEXIBLE BASE Russian patent published in 1994 - IPC

FIELD: techniques for application of thin coatings to movable flexible base, particular, techniques of application of photoemulsive layers in production of light-sensitive materials. SUBSTANCE: directly after application of coating to base, parameters of spectral components of coating thickness variation are measured by nondestructive method using indirect parameters - optical density or application of moisture of raw nondeveloped emulsion layer. Obtained parameters are compared with preset ones for each type of material with its structure consideration. EFFECT: higher efficiency. 1 dwg
