US Patent:

8288502, Oct 16, 2012

Filed:

Dec 18, 2009

Appl. No.:

12/641557

Inventors:

Heinrich E. Bode - Aurora IL, US
Michael R. St. John - Chicago IL, US
Mei Liu - Plainfield IL, US
Robert M. Lowe - Chicago IL, US

Assignee:

Nalco Company - Naperville IL

International Classification:

C08G 2/00

US Classification:

528246, 1621641, 525267

Abstract:

The current invention includes a composition having stability additives of selected inorganic salts and/or organic incorporated into an aldehyde-functionalized polymer product. The stability additive can be post added to the finished polymer product, added to the reaction vessel prior to inducing functionalization of the non-functionalized polymer, or added at any stage during the functionalization reaction. Methods for forming the composition and using the composition to produce a cellulosic fiber-based medium are also disclosed.

Appl. No.:

13/611450

Inventors:

Robert M. Lowe - Chicago IL, US
David J. Castro - DeKalb IL, US

International Classification:

C08L 77/00
D21H 23/00
D21H 17/55
C08K 5/1539

US Classification:

1621646, 524112, 524270

Abstract:

The invention is directed towards methods and compositions for improving the sizing of paper using PAE. Proper sizing of paper requires that a sizing agent adequately disperse so as to evenly distribute on the paper. Proper sizing also requires that the agent not cause runnability or chemical problems with other materials or equipment used in the papermaking process. PAE displays unexpected attributes that allow it to disperse sizing agents. Best of all it is not subject to the same overdose effect of typical emulsifiers such as cationic starch. As a result PAE is an excellent option for use in sizing paper.

International Classification:

F25B 49/00
F25B 19/00
H05K 7/20

Abstract:

The disclosed systems and method for evaluating the integrity of media pads within an adiabatic cooling system includes at least one media compartment containing at least one media coupon that is representative of at least one of the media pads. The system is adapted to be fluidly coupled to a source of representative process water and to provide such water to the at least one media compartment. A source of airflow fluidly is also coupled to the at least one media compartment. The flow of representative process water and airflow to the media coupon within the media compartment simulates the operation of the adiabatic cooling system. The at least one media coupon may then be analyzed as representative of media pads within the adiabatic cooling system.

Abstract:

An acrylamide-based polymer which contains one or more multiquaternized (“multiquat”) monomer unit(s) is provided. The acrylamide-based polymer can be used in a papermaking process to reduce pitch and stickies deposition, improve retention and drainage, and enhance dry strength properties of paper. Also included is a method of controlling pitch and stickies deposition in papermaking comprising treating pulp slurry with an acrylamide-based polymer which contains one or more multiquaternized (“multiquat”) monomer unit(s).

Abstract:

Methods of reducing paper dusting in a papermaking process, and a low dusting tissue having increased strength are provided. Application of a polymer comprising at least one amine-containing vinylic or allylic monomer to at least one surface of a paper web during the papermaking process reduces the dusting tendency of the paper, and inpcreases both the wet and dry strength of the paper product.
