JOURNAL FREE ACCESSIt has been considered that runnability of high speed coating is much influenced by dewatering and rheological properties of coating colors.
Rheological fundamentals which are necessary for understanding of coating color properties are introduced in the first part of this report, with some qualitative explanations concerning viscoelasticity and shear rate dependence of viscosity of coating colors.
In the middle part of this report, practical discussions concerning dewatering and rheological properties of coating colors are introduced with experimental results affected by many types of color formulations varied by pigment types, solid content, level of water soluble binder, types of SBR latexes.
In the final part of this report, a way how to understand the relation between properties of coating colors and runnability of high speed blade coating is discussed.View full abstractDownload PDF (4065K) -

JOURNAL FREE ACCESSIn this paper, we introduce the latest technology of coating and finishing process. Advanced Coating Technology (AFT) and Advanced Finishing Technology (ACT) are key concepts of Measurrex Devron. And new measurement and control technologies have been developed in the recent years for coating and finishing process. Key subjects of this article are direct coating measurement using infrared sensors, cross direction coat weight control, optimized drying control with gas IR dryers, caliper control on soft nip calenders and sheet surface sensors with laser method. This paper also describes the successful results of these subjects.View full abstractDownload PDF (3535K) -

JOURNAL FREE ACCESSIn the previous paper (this journal : 49 (12), 114 (1995)), 23 kinds of phenol carboxylic acids were selected, and their antibiotic activities were tested to clarify the effect by the chemical structure of phenol carboxylic acid. Unfortunately, it was difficult to systemize the activity by the relative position of phenol hydroxyl and carboxyl groups on aromatic nucleus.
This paper deals with the antibiotic activities of variously alkali degraded thiolignins. It is worth-while to note that the original thiolignin does'nt show the antibiotic activity. The results are summarized as follows :
(1) The antibiotic activity of modified thiolignin differs considerably by the species of microorganisms.
(2) The ethanol soluble fraction of modified thiolignin shows the antibiotic activity toward microorganisms, except Aspergillus niger.
(3) The activity becomes higher with the increase of modified thiolignin. This, however, becomes constant after over a definite amount of modified thiolignin added.
(4) Alkali fused thiolignin shows the highest activity among the modified samples.
(5) Carboxyl groups of modified samples increase by the alkali treatment. The position of carboxylic acid was discussed by C-13 NMR measurement, and the presence of phenol carboxylic acid was concluded.View full abstractDownload PDF (2865K) -

JOURNAL FREE ACCESSScreening of fungi having ability for decolorization of dye was carried out by using Remazol brilliant blue R, a kind of dye, as an indicator. Twenty three fungi having ability for the decolorization of the dye were found by the screening from 195 samples of decayed woods and soils. Among them, three fungi named 563, V 1, and V 2 had higher ability for the decolorization of the dye than those of other fungi separated by the screening. Microbial degradations of 2, 7-Dichlorodibenzo-p-dioxin (2, 7-DCDD) by the three fungi (563, V 1, and V 2) separated by the screening and by three wood-rotting fungi having ability for biodegradation of lignins (Phanerochaete chrysosporium, Coriolus versicolor, and Fusarium solani) were conducted. The six fungi degraded 24.1% to 83.1% of 2, 7-DCDD. The maximum rate of degradation of 2, 7-DCDD was obtained by fungus V 2 when the incubation was conducted for 15 days after addition of 1.25 m Mol of 2, 7-DCDD to culture medium of each of six fungi. The rate of the degradation was 61.8%. In the case of the 30 day's incubation in the same concentration, the maximum rate of the degradation was obtained by P. chrysosporium. The rate of the degradation was 65.8%. On the other hand, the maximum rates of degradation of 2, 7-DCDD were obtained by fungus V 2 when the incubations were conducted for 15 and 30 days, respectively, after addition of 0.25 m Mol of 2, 7-DCDD to culture medium of each of six fungi. The rates of the degradation were 83.1% and 79.9%, respectively. In addition, a part of 2, 7-DCDD was incorporated into each mycelium of six fungi during the incubation. The rate of degradation of 2, 7-DCDD increased with increase in the lignin peroxidase activity in extracellular crude enzymes solution from six fungi.View full abstractDownload PDF (2970K) -
