摘要： An agent for preventing scale formation and a method for preventing scale formation include a polymer which has at least 50% of N-vinyl formamide units or N-vinyl acetamide units and a phosphorus compound added to water in a cooling water system, a boiler water system, or the like. The scale preventing agent and scale preventing method of the present invention are effective in preventing the adherence of various types of scales which are generated in cooling water systems, boiler water systems, and the like. In particular, the present invention is effective in preventing the adherence of silica and calcium scale.
