ジャーナル フリーOn the basis of 38 year career with Jujo Paper Co., Ltd., three essential subjects-How to make the best of engineers ? Which way paper technology should go ? How to get the job done, easy, quick and right ? -are discussed. On the human side, emphasis is put on education, communication and empowerment. A boundaryless, pecking orderless and womanfriendly organization is touched upon. On the technical side, standardizing dimensions of paper machine rolls and clothes is suggested. Facing with engineer crunch, the author believes in advantages of the engineering firms specialized in mill construction, a new concept to the Japanese paper industry. In order to thrive and yet contribute to the world environment, the industrywide effort to develop fast growing fiber resources is most desired.抄録全体を表示PDF形式でダウンロード (6470K) -

ジャーナル フリーThis paper reviews on printability aids which are added to pigment coating color for the improvement of printability.
The function and the mechanism are described and newly developed printability aids, “Epinox P-593 and P-363” are also introduced, which are superior to conventional printability aids.抄録全体を表示PDF形式でダウンロード (3003K) -

ジャーナル フリーThe experiments were carried out to produce PHB (Poly-β-Hydroxybutyrate) in activated sludge. The production of PHB under nitrogen limited condition was confirmed and CH3COONa was better than glucose as carbon source for production of PHB. Content of PHB was stabilized to its maximum stage around 250 hours by continuous process and it was achieved to 12% of dried sludge weight basis. PHB was slowly accumulated and consumption than carbohydrate in batch process.抄録全体を表示PDF形式でダウンロード (4605K) -

ジャーナル フリーMitsubishi Heavy Industries, Ltd. had developed the automatically-controlled warehousing system, which can achieve the easy handling of paper rolls with minimum workers in small space of the warehouse. This system consists of ;
(1) full-automatically controlled overhead cranes with the gripping device originally designed by MHI.
(2) infeed and/or discharge conveyor systems.
(3) computer system for inventory and location control.
Comparing with a conventional forklift handling system, the following advantages can be achieved.
(1) about two times amount of paper roll storage in the same stock area.
(2) reliable inventory control.
(3) quick discharge of paper rolls.
(4) labor cost saving by the minimum workers.
(5) space saving.
(6) clean atmosphere in the warehouse.
(7) safety operation.抄録全体を表示PDF形式でダウンロード (5526K) -

ジャーナル フリーThe viscoelastic properties of binder latices for paper coating were investigated, together with dynamic viscoelastic properties of latex films and electron micrographs of latices, under various conditions. The amphoteric latex, binder-pigment latex and anionic latex were used in this work. The amphoteric latex has both anionic and cationic functional groups on its surface. The binder-pigment latex with a core-shell structure has dual functions : plastic pigment and binder.
The low-shear and high-shear viscoelasticity of binder latices and clay slurry were measured with Brookfield viscometer and Hercules high-shear viscometer, respectively.
At low-shear rates, the viscosity decreased with increasing particle size of latex. However, at high-shear rates, the different results were observed.
On the amphoteric latex surface, the carboxyl groups are assumed to be fully dissociated over the region of pH 9-12, but the density of negative groups seems to increase because of the gradual decrease in the degree of dissociation of amino groups. Since the apparent particle size of latex increases with surface charge, the electroviscous effect, i. e. increase in viscosity by surface charge, can be observed. On the anionic latex surface, the charge density is assumed to be nearly constant above pH 8. However, below pH 8 the coagulation of particles could be observed probably because of the decrease in charge density.
The time-dependent phenomena could not be observed at low-shear rate. However at high-shear rate, thixotropic properties of flow, and the internal structural breakdown of flow could be observed from time-dependent phenomena.抄録全体を表示PDF形式でダウンロード (6065K) -
