A method to prevent deposits on a ceramic surface comprising: (1) pretreating the surface by applying an aqueous solution containing from about 200 ppm to about 1000 ppm by weight of an amphoteric fluorosurfactant, and (2) periodically applying an aqueous maintenance solution comprising from about 1 ppm to about 200 ppm of at least one of an amphoteric or cationic fluorosurfactant or a mixture thereof, from about 5 ppm to about 100 ppm of a sequestering acid, and from about 2.5 ppm to about 200 ppm of a quaternary ammonium biocide compound, wherein all concentrations are by weight of aqueous solution is disclosed.
一种防止陶瓷表面沉积物的方法,包括:(1) 通过施用含约 200 ppm 至约 1000 ppm (按重量计)两性表面活性剂的
水溶液对表面进行预处理;(2) 定期施用含约 1 ppm 至约 200 ppm 的两性或
阳离子表面活性剂或其混合物中的至少一种、约 5 ppm 至约 100 ppm 的固着酸和约 2.5 ppm 至约 200 ppm 的季
铵杀菌剂化合物,其中所有浓度均以
水溶液重量计。
