Vor Kesselstein und/oder Korrosion schützende Zusammensetzung |
摘要 |
This invention relates to scale and/or corrosion inhibiting compositions for aqueous systems comprising (a) polyaspartic acid, and (b) a water soluble phosphonated oligomer. The compositions are effective scale inhibitors and corrosion inhibitors, but are also advantageous from an environmental standpoint because they are non-toxic, contain no heavy metals, and have little phosphorus. They also have significant calcium/hardness tolerance and are chlorine/bromine stable.
