A Study Of The Models Describing Fines And Filler Retention By Utilizing Cationic Starch As The Retention Aid, Nen-Sen Chen Dec 1980

A Study Of The Models Describing Fines And Filler Retention By Utilizing Cationic Starch As The Retention Aid, Nen-Sen Chen

Masters Theses

Fines and filler retention under dynamic conditions was studied in this thesis work. Zeta potential of samples are also measured. Dynamic Retention/Drainage Jar and Lazer-Zee Meter were used to accomplish this work. The results have been analyzed by statistical methods. When cationic starch was utilized as a retention aid the pH affected its efficiency, probably because the charge of cationic starch was dependent on pH. This effect was detected by utilizing two-way analysis of variance to find the sources of its interactions with molecular weight and agitation rate. The mechanism was thus determined. At pH 3 and 4, charge neutralization …

The Lb Wind-Tunnel, Larry Bennett Jan 1980

The Lb Wind-Tunnel, Larry Bennett

Honors Theses

A small subsonic wind-tunnel has been developed for further understanding of aerodynamic principles. This tunnel is small enough to be used on table tops so the student can get first-hand experience. The tunnel's working section is a clear plexiglass tube for easy viewing and provides ample work room. The biggest advantage of this tunnel is that it can be built in the average home workshop for approximately $60.00.
