Problems solved by technology

For example, impurities from rubber and silicone coatings can build up on the surfaces of machine components, affecting the performance of production equipment as well as the quality of recycled paper products
The result is that the paper mill needs frequent shutdowns to clean the machinery of contaminants
The cleaning process is expensive and results in an overall loss of productivity

Abstract

Surfactant penetrant treating solutions and their use in the manufacture of paper products. The surfactant penetrant treating solutions include two types. The first type is an enzymatic surfactant penetrant treating solution, and the second type is a defoaming surfactant penetrant treating solution. The solutions may be used to break down recyclable paper products for use as feedstock in paper manufacturing processes. The solutions may also be used to clean the internal and external components of machinery in a paper manufacturing line.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application Nos. 60 / 716,704 filed September 13, 2005; 60 / 723,674 filed October 5, 2005; 60 / 759,492 filed January 17, 2006; Priority No. 60 / 784,365 filed March 21, each of which is hereby incorporated by reference in its entirety. Background technique [0003] The papermaking process typically involves reducing a material to its fibrous structure and then rearranging those fibers to make a paper product. These fibers are available from a variety of sources including paper cloth, seed fibers, jute, flax, grasses, animal fibers and plant fibers. More recently, fibers from recycled products have become an important raw material for paper mills, either alone or in combination with fibers from other sources. [0004] Despite centuries of papermaking experience, the industry still faces many technical challenges. Existing methods for breaking down recyclable paper products used as pap...
