This senior project designed a two-phase process, first phase being prevention and second phase being a lean …


An Investigation Of The Efficacy Of Corn Cob Hemicellulose As A Gas Barrier And Dry Strength Agent On Previously Uncoated Linerboard, Zachary Witherspoon Apr 2018

An Investigation Of The Efficacy Of Corn Cob Hemicellulose As A Gas Barrier And Dry Strength Agent On Previously Uncoated Linerboard, Zachary Witherspoon

Honors Theses

Two types of xylan, water soluble and insoluble, were extracted from corn cobs and made into liquid coatings and applied to uncoated linerboard with a fine, #8 Meyer rod, with the intention of creating a gas barrier and increasing strength properties. The xylan coatings were plasticized with sorbitol and crosslinked with citric acid, and the crosslinking reaction catalyzed with sodium hypophosphite. A 1% konjac glucomannan comparison coating was created (with the same plasticizer and crosslinker) to serve as an alternative coating based on previous research in the department, but it failed as a paper coating due to the presence of …

It is recommended that this compressor, along with two 35hp compressors already purchased by Parker be tied together using an automated system. In addition to the compressor, a flow controller was recommended to be implemented into the system.

Given that leaks are also a problem in the system, it is recommended that the majority of air leaks in the system be fixed …
