    • PURPOSE: To provide a zinc phosphate treating soln. free from the generation of sludge and to provide a zinc phosphate treating method. CONSTITUTION: In this zinc phosphate treating soln., the respective molar concns. of Zn, H3PO4 and NHO3, i.e., £Zn|, £H3PO4| and £HNO3| satisfy the inequality of £Zn|= = two kinds of additives selected from nitrous acid, permanganic acid, persulfuric acid, hydrogen peroxide, chloric acid, perchloric acid, nitrobenzenesulfonic acid, hydroxylamine, starch phosphoric ester and a fluorine compd. As to the zinc phosphate treating method, a metallic member as the object is subjected to cathode electrolyzing treatment in the zinc phosphate treating soln. Or, the metallic member as the object is brought into contact with an alkalescent colloid aq. soln. contg. titanium oxide, titanium hydroxide and zinc phosphate, which is thereafter subjected to cathode electrolytic treatment in the zinc phosphate treating soln.

    • PURPOSE: A composition of a corrosion inhibitor for medical devices is provided to reduce chemical resistance generated in a boundary surface of grains or a local action of an electrolytic because a surfactant reduces a tension of a metallic surface of medical devices so that corrosion is prevented. CONSTITUTION: A composition of a corrosion inhibitor for medical devices comprises 0.5~15wt.% of an antioxidant and 0.05~5wt.% of a surfactant. The antioxidant comprises one kind being selected among polyphosphate, metaphosphate, and alkanolamine. An enhancer comprises one or more kinds being selected among citric acid, maleic acid, and metallic salt thereof.
    • 目的:提供一种用于医疗器械的防腐剂的组合物,用于降低由于表面活性剂降低医疗器械的金属表面的张力而导致的腐蚀,从而降低了晶粒边界面产生的耐化学性或电解质的局部作用。 构成:用于医疗装置的缓蚀剂组合物包含0.5〜15重量%的抗氧化剂和0.05〜5重量%的表面活性剂。 抗氧化剂包括一种选自多磷酸盐,偏磷酸盐和链烷醇胺。 增强剂包括选自柠檬酸,马来酸及其金属盐中的一种或多种。
