XPJ972 Esterified Polyether Paper Defoamer
Product Introduction
Defoamers are needed in Kraft mills, recycle mills, sulfite mills, and other pulping processes, and are utilized in the following broad applications:
● Pulping (brown stock washing, screen room, bleach plant)
● Paper making
● Coating
● Effluent treatment
XPJ972 is a broad-spectrum polyether defoamer developed for foaming in paper making section. The product has good performance and is convenient to use. It is easy to disperse in white water. It can maintain good degassing and antifoaming effect at low concentration. Widely used in copperboard paper, cultural paper, kraft paper, newsprint, daily paper and other papermaking processes defoaming; The product is temperature-resistant, non-induced paper disease, easy to coating processing and printing; It can also be used as foaming inhibitor for the manufacture of papermaking chemicals, as well as in the production and use of rosin sizing agent.
