ジャーナル フリーThe pulp consistency transmitter is one of the most important sensors in the pulp and paper manufacturing industry. The need for an absolute sensor for direct measurement of dry weight in the mixture is paramount, but is not yet commercially available. However, even the characteristics of conventional sensors, which measure the relative value of pulp, are not fully understood.
Sensor-type selections vary among pulp and paper companies. Some companies use mostly the Blade-type, while others use the Rotating-type.
This comparison trial focused on the two prevalent types of consistency transmitters, Blade and Rotating, by observing the sensitivity to concentration of pulp and the influence of velocity. Thus, the Blade transmitters, which have an economical advantage, and the Rotating transmitters can both be evaluated fox operating characteristics.
The trial results can lead not only to future applications of the Blade sensors, but also give us a deeper understanding of the pulp consistency transmitters.抄録全体を表示PDF形式でダウンロード (1011K) -

ジャーナル フリーDevelopments in non-chlorine bleaching technology over the last few years has made it viable to consider the closed cycle bleach plants pursued by designers over twenty years ago. The market demand for low and total chlorine free pulp has made operation of bleach plants without elemental chlorine (ECF) and without any chlorine (TCF) not only feasible but commercially successful in a number of mills around the world. Although there is yet to be a totally effluent free mill operate on chemical pulps, this seems the vision for a number of pulp and paper company executives for the future.
In this paper, the requirements for successful production of TCF pulps are reviewed, and details of bleach plant design are discussed, using ozone and peroxide as bleaching chemicals.抄録全体を表示PDF形式でダウンロード (1114K) -

ジャーナル フリーKraft pulping anti-foaming agents have been used as an indispensable additive for smooth pulping operation since 1950's with the introduction of Kamyr digester. As foam related problems, there are soda loss, increase of bleaching chemicals, increase of evaporator load, increased load for water treatment and pitch trouble due to poor washing, as well as repulping control trouble and sheet break. Therefore anti-foaming agents which can improve these problems have come to the essential additive for Kraft pulping process.
We herewith would like to report the trend of Kraft pulping anti-foaming agents and also silicone emulsion type anti-foaming agents which are developed recently and are now begun to used worldwide.抄録全体を表示PDF形式でダウンロード (716K) -

ジャーナル フリーWe have studied the function of polymeric dispersants on aqueous concentrated pigment dispersions, which consists of pigment, polymeric dispersant, and water. To clarify the function of dispersants, sodium polyacrylate [A] and alternating copolymer composed of sodium acrylate and sodium maleate [B] were used.
The rheological properties were examined as to the pigment dispersions prepared using each of [A] and [B]. The results indicate the followings.
(1) [A] shows good dispersing efficiency with less dosage relatively to [B].
(2) At low shear rate, the pigment dispersions containing [B] (slurry B) shows lower viscosity than the dispersions containing [A] (slurry A), if the dosage of dispersants is sufficient.
(3) The viscosity of the slurry B is shear-thickening (dilatant).
To clarify the function of [A] and [13], the zeta-potential of the pigment particles was measured and the correlation was examined between the zeta-potential and the slurry viscosity. Here, the zeta-potential was measured by the newly-developed Electro-kinetic Sonic Amplitude (ESA) method. A strong correlation was observed between the zeta-potential and the slurry viscosity. The results reveal that the slurry B has high viscosity because much lower zeta-potential of the particles is observed in [B] compared to [A] at low dispersant dosage.
From the rheological properties observed and the measurement of the zeta-potential, we presume the adsorption on the pigment particles of [A] and [B] as follows : [A] has less adsorption points to the pigment particles, forming thicker adsorption layer. On the other hand, [B] has more adsorption points to the pigment particles, forming thinner adsorption layer.
Based on these studies, we have developed high performance dispersant for pigments called [POLITY A-550], which combined the advantages of [A] and [B].抄録全体を表示PDF形式でダウンロード (1108K) -

ジャーナル フリーCurrently starch is the predominant strength agent for spraying between layers (SASL) for its low cost despite apparent disadvantages in handling or processing.
PAM strength agent that was expected to overcome these difficulties has been unsuccessful to fully replace starch because of cost problem.
This paper discourse the discussion on the fixation mechanism of SASL and development of new SASL polymer based on this new rational for better fixation on pulp.
Since this newly developed SASL -KW-901- is supplied in solution form its obvious merits are ease of handling as well as much better fixation on pulp due to the particle forming characteristics upon dilution thus resulting in good cost performance.抄録全体を表示PDF形式でダウンロード (1058K) -

ジャーナル フリーInteractions between chemical species (pulp, alum and/or PAM (polyacrylamide)) contained in a pulp slurry were investigated by means of chemical analysis and optical microscopy. After rapid filtration of pulp slurry containing alum the aluminum content in pulp was drastically changed around pH 4.5. In the pH region from 5 to 7, aggregates measuring several ten microns in diameter were observed in the slurry, but in the filtrate aluminum was hardly detectable. The aggregates interacted strongly with amphoteric PAM and weakly with pulp. We proposed a hypothesis which chemically describes the process from preparation of slurry to evaluation of paper through paper making. Aggregates derived from alum control the amount and position of amphoteric PAM in paper.
The amount of PAM in paper increased with increasing amount of alum in slurry in the pH 5 to 7 region, while in alum-free systems decreased with increasing pH in the same region.
We found that phosphomolybdic acid easily dyes PAMs blue or green, and first succeeded to observe the PAM morphology in paper by means of the scanning electron microscopy.抄録全体を表示PDF形式でダウンロード (12394K) -

ジャーナル フリーWe are a manufacturer of plain or non-printed web inspection systems for like papers, films, metal foils and others. We also manufacture printed web inspection systems by which the print quality on the above plain web is scanned. The cumulative number of systems delivered has reached the level of 2, 400 units. With this unparallel experience, we propose the integrated system for paper and pulp industries.
To be more specific, the print quality is more or less related with the raw material quality. Occasionally, the raw material contains various fatal defects to printing while it is being processed, like smears, streaks, black specs and paper dust. This creates a difficult situation for printing industries when make the quality assurance to their customers.
The inspection system for paper and pulp industries are required the capability of very high speed. Compared to printing and converting processes, the speed requirement of paper and pulp industries is substantially more. In order to achieve such very high speed inspection, the systems has to have FUTEC's QC In-line data process package, which controls the high speed spot detection unit, faint smear detection unit, and video image display unit. This FUTEC's QC In-line data process package, which stores vast defect data in data base format, can only offer feasible systems to paper and pulp industries where unimaginable stringent environment exists.抄録全体を表示PDF形式でダウンロード (10652K) -

ジャーナル フリーIn development of industrial biocide, formulation technique is becoming important to assure safety. Isothiazolone is an excellent raw material as a general purpose biocide, but has a disadvantage that it is irritative to human skin and requires caution in handling.
To solve these defects, we studied inclusion of isothiazolone into a clathrate compound, and succeeded in greatly reducing the skin-irritative property of isothiazolone without sacrificing the biocide effect.
The host itself has a biocidal effect, so the clathrate gained a synergistic effect in preventing growth of Bacillus sp. in starch. The flowable product developed in this study has reduced skin-irritation, improved compatibility with coating color, without any adverse effect on high-shear viscosity of the coating color.抄録全体を表示PDF形式でダウンロード (2076K) -

ジャーナル フリーRecently die coating has been attracting attention because of several advantages over roll coating. The suitable design of a die nozzle is the key to obtaining a good coated surface in die coating under various conditions. Numerical simulation is an effective method to design the optimum die nozzle. It is very important to use a solver suitable for an object of analysis in numerical simulation.
In this work we, using the solver “Nekton”, analyzed a die coating flow, and compared the result of the analysis with the experimental data about :
(1) the relationship between the capillary number and the minimum wet thickness
(2) the relationship between the bead vacuum and the minimum wet thickness
(3) the relationship between the fluid viscosity and minimum wet thickness with bead vacuum.
As a result we have found the same tendency with the experimental data and confirmed that this solver is applicable to die coating.抄録全体を表示PDF形式でダウンロード (679K) -

ジャーナル フリーStarting in the 1980's, there has been a movement in Japan to improve coating efficiency and reduce steam consumption through moving the coating process from the size press to the Gate-roll or Bill-blade coater. Additionally, the Gate-roll coater is gaining popularity as a countermeasure to reduce linting problems which increasingly occur with the growth of offset printing for newspaper. Starch is a commonly used coating agent with the Gate-roll coater, but many problems, such as poor water resistance, have been reported.
To solve these problems, we have extensively studied the relationship between the viscosity and coating efficiency of polyacrylamide (PAM) coating agents. We discovered that very high molecular weight PAM coating agents displayed the best coating efficiency. Based on our research, Haricoat G-3000, a high molecular weight PAM coating agent, was developed.
Application of Haricoat G-3000 alone or in conjunction with starch coating agents offers the following benefits.
1. Excellent surface strength and printability
2. Prevention of size deterioration during the coating process
3. Clear and vibrant print obtainable even when using plain paper with an ink jet printer抄録全体を表示PDF形式でダウンロード (4420K) -

ジャーナル フリーIn coated paper production, the high solid-high speed coating is the main stream of the recent coating technology with respect to productivity, final coated properties and cost of energy consumption for drying.
Bleeding phenomena including stalagmite, bleeding and so on are becoming severer with increasing coating speed and solid content. Therefore, these days, the countermeasure for bleeding is desired.
Many papers and investigation results concerning bleeding phenomena were presented so far, and it is estimated that the main causes of bleeding were summarized as follows, :
(1) Apparent viscosity of coating color at a high shear rate
(2) Dynamic dewatering behavior of coating color
(3) Dynamic viscoelastic behavior of coating color
In this study, influences of apparent viscosity and dynamic dewatering of coating color on bleeding were investigated by pilot coater trials and labo-scale measurements of coating color properties.
It was found that apparent viscosity at a high shear rate did not simply correlate with bleeding results.
Bleeding results, however, showed a very good correlation with the apparent viscosity modified by dynamic dewatering of coating colors.
How to calculate to introduce dewatering to apparent viscosity was proposed in order to predict bleeding results.
It was also found that a newly developed latex having particle size around 100 nm showed the better color rheology and water retention than the conventional one, therefore showing the excellent bleeding result.
The above result is thought to be an intrinsic performance only for the new latex.抄録全体を表示PDF形式でダウンロード (5744K) -

ジャーナル フリーThe Parker Print-Surf is unique amongst air-leak roughness measuring instruments in that it attempts to measure paper roughness under conditions which simulate those found in the printing process. The essential components of the instrument are an air flow resistance measuring system, a measuring head, a resilient backing for the test piece and a pneumatic press to press the test piece against the measuring head. It has been found that, if the test piece is stiff or thick, as might be the case with boards, the test piece tends to bend away from the measuring head, giving higher than expected roughness values. A simple modification to the design of the resilient backing holder has been developed which overcomes this problem.抄録全体を表示PDF形式でダウンロード (959K) -
