1.Papermaking environmental sewage treatment defoaming and foam suppressant
The papermaking environmental protection sewage treatment defoaming agent is emulsified by non-toxic, harmless and physiologically inert kinds of functional silicone oils. It has stable performance, fast static defoaming speed, long dynamic foam suppression time, no toxic to sewage microorganisms, and does not change the performance of COD and BOD in sewage.
2. Pulp defoamer function description
It is widely used in the process of the river, and the elimination of a large amount of foam caused by chemical and mechanical action such as lignin, acid organic matter, inorganic component, sodium combination, and extract (wood resin) and suppression of foam in the process Produced again, (suppressing time > pulping process period). At the same time, the papermaking defoamer has extremely high temperature resistance (up to 120 ° C), and is also suitable for defoaming and foam suppression in the process of extracting lignin by using black liquor (red liquor). In the industry of papermaking using waste paper (recycled paper), papermaking defoamers can also eliminate various types of foams generated during processes such as deinking, bleaching, and sterilization.
3. Paper-making defoamer function description
The chemical action of the paper-making defoamer is to eliminate the foam in the white water. Because of the white water circulation, after the first phase is added, the anti-foaming agent is gradually reduced due to the strong anti-foaming performance of the product. At the same time, it has the defoaming and antifoaming properties of various artificially added surfactants, lignin, synthetic polymer, starch, fatty acid, resin acid soap and deinking agent in the pulping process. The correct use of paper-making defoamer can ensure the control of physical indexes such as paper strength, quantification and tightness.
