SCALE-INHIBITING COMPOSITIONS |
摘要 |
Compositions which will inhibit the formation of scale due to calcium carbonate precipitation in recirculating water systems will comprise a mixture of polyvinylpyrrolidone and aminotri(methylenephosphonic acid). The compositions will be present in the water system in a range of from about 2 to about 25 ppm of said system and will contain the components of the composition in a mole ratio in the range of from about 1: to about 1:10 moles of polyvinylpyrrolidone per mole of phosphonic acid. |
