Method for preparation of thermal insulation board

Abstract: A METHOD OR PROCEDURE FOR THE PREPARATION OF THERMAL INSULATION BOARD WHEREIN A CERAMIC FIBER SUCH AS FIBERFRAX IS SLURRIED WITH SILICA SOL AND SEQUENTIALLY WITH A SOURCE OF ALUMINA. THE SOLUTION IS ADJUSTED TO A SLIGHTLY ACIDNEUTRAL PH OF 5-7 AND THE ALURRY IS FLOCCULATED WITH A MINOR AMOUNT OF AN ANIONIC POLYMER CONSISTING OF A LATEX OF ACRYLAMIDE/ACRYLIC ACID. THE FLOCCULATED MIX IS SUBSEQUENTLY VACUUM FORMED AND DRIED UNDER CONVENTIONAL PROCEDURES.

Method of applying a super-absorbent composition to tissue or towel substrates

Abstract: The invention provides a method of increasing the absorbency of an absorbent article. The method includes introducing a super-absorbent polymer composition to a paper web in a papermaking process to increase the absorbent capacity of an absorbent article made in the process. The polymer composition includes a super-absorbent polymer and a cross-linking agent applied to the paper web. The paper web is then subjected to heat in a heated drum or a through-air drier to cure or cross-link the super-absorbent polymer.

Modifying agent for yankee coatings

Abstract: The invention provides a composition of matter useful for producing very soft high grades of tissue paper. The composition of matter comprises an adhesive composition that includes a glycerol-based polyol. The glycerol-based polyol prevents the composition from becoming brittle and is non-volatile. This allows the composition to become rewetted after creping and allows for strong levels of adhesion even at high temperatures.

Pseudo-fouling detector and use thereof to control an industrial water process

Abstract: A system and method are provided which enables the monitoring and if desired controlling of fouling within a fluid system. The present invention includes a pseudo-fouling detector system with a pair of identical sensors, where said sensors measure a variable, such as, temperature or pH, in a fluid, producing an electric output representative of the variable. The variable measurements are used to calculate a fouling index which is further used to develop fouling treatment strategies for controlling the amount of fouling in the fluid system.
