Mechanism of the Delignification ProcessNobuhiko Suguri, Tamio Kondo1971 Volume 25 Issue 1 Pages 18-24
Published: January 01, 1971
Released on J-STAGE: November 10, 2009
JOURNAL FREE ACCESSAn attempt is made to provide a more rational basis than is presently available for analysing the delignification mechanism of the hydrotropic cooking in respect to physicochemical property of the hydrotropic reagents. In so doing, consideration is given to defining the role of the micell formation of the hydrotropic solutions upon the delignification process and the examination of the affinity which can be properly observed between the lignin molecules and the hydrotropic micells. Some data of the physicochemical observations are examined by these criteria. The results of the study colloborate the micell formation theory and supply further data relating to the hydrotropic reagents in lignin removal.View full abstractDownload PDF (1304K) -
Part IV. On the Theoretical Explanation of the Tape Printing MethodShoji Ando1971 Volume 25 Issue 1 Pages 25-32
Published: January 01, 1971
Released on J-STAGE: November 10, 2009
JOURNAL FREE ACCESSThis report presents the theoretical explanation for the Tape Printing Method. The “Duble Reflexion Theory” was proposed, and the formula described below was introduced for the Tape Printing contrast C1
C1=1/1-G(x, n)
G(x, n) is the numbers of index for the normal reflexion of lightbeams focused on the surface of adhesive tape.
G(x, n)=1/2{tan2(ψ-x)/tan2(ψ+x)+sin2(ψ-x)/sin2(ψ+x)}
n=sin x/sinψ
“x” is the incidence angles of light beams. “n” is the refraction index of the adhesive tape.View full abstractDownload PDF (8437K) -
