ジャーナル フリーMedium consistency ozone bleaching plant was started up at Yufutsu mill in January 2001. This is the first plant that use ozone gas as a bleaching sequence in Japan. By changing conventional C/D-E/ op-D into ZD-E/op-D, we have entirely excluded the usage of elemental chlorine. The ozone generator is the maximum class in the world as one unit capacity, which can provide a high concentration of ozone in oxygen (12% by weight) at a designed output of 120 kg of ozone/hr.
The pulp that is bleached by the ozone ECF sequence has not had any troubles with a quality of the paper products. The cost of ozone ECF is lower than the cost of ECF that was made from chlorine dioxide as a main bleaching chemical. The results of the ozone ECF is as good as was expected from the laboratory studies. Effluent AOX and chloroform emissions have decreased significantly for starting up the ozone bleaching plant.抄録全体を表示PDF形式でダウンロード (5359K) -

ジャーナル フリーOxygen bleaching sequence, efficient washing system and reinforced effluent treatment facilities that had been introduced in Hachinohe mill of Mitsubishi Paper Mill since 1988, was allowed to reduce adsorbed organic halogen (AOX) with greatefficiency. However the global environmental demand intensely trends toward more and more reduction of emission or pollution. In view of the situation, the introduction of the elemental chlorine free (ECF) bleaching sequence to Hachinohe mill has been decided in 1999.
In October 2000, No. 3 BKP-line, the product line of LBKP, was adapted for ECF bleaching sequence with the minimum conversion of existent bleaching facilities except continuous cooker, washing facilities oxygen bleaching stage and so on. D0 (E/O) PD, sequence, in which the existent bleaching towers could be used, was selected for the ECF bleaching sequence on No. 3 BKP-line.
It was found that the brightness of oxygen-bleached pulp instead of the kappa number of Oxygen-bleached pulp dominated the bleaching efficiency on ECF bleaching sequence in contrast with the conventional chlorine bleaching sequence. In the operation of ECF bleaching sequence, the prevention of scale and the reduction of bleaching chemicals have been carried out.
In this report, we describe the operational experience of ECF bleaching in this last year and discuss the main issues in ECF bleaching such as the influence of hexeneuronic acid in unbleachedpulp.抄録全体を表示PDF形式でダウンロード (2040K) -

ジャーナル フリーDaishowa Honsha Mill Suzukawa converted the oxygen delignification to a two-stage system. Increasing production capacity and dealing with conversion from chlorine-based to ECF bleaching were the main reasons behind the investment of two-stage oxygen delignification (DUALOX) system. The benefits of Dualox system are the intermediate MC pump as a booster, compact pre-reactor (TUBE), and simple system. Since the start-up in November 2000, the kappa reduction has increased by 4.6 point, brightness of unbleached pulp by 2.2 point, and viscosity by 0.7 point. This improvement of unbleached pulp qualities has achieved a 10% savings on bleaching chemicals, and a 10% reducing COD effluent load.抄録全体を表示PDF形式でダウンロード (4430K) -

ジャーナル フリーThe contaminant and pitch which sticks on the backing roll was the problem for the quality of the coating. Despite the use of flow-clean cleaning system on the backing roll, there were still problems of the build up pitch when operating nonstop for few days. To clean the roll, operator needed to scrape off the backing roll with the sandpaper. The new device was developed for automation of the cleaning with sandpaper.
Development was a great success, Auto-Sanding-Device was able to clean the roll. The flexibility of the device made it possible to clean the roll during the operation. This report introduces about the development and the device itself.抄録全体を表示PDF形式でダウンロード (8167K) -

ジャーナル フリーWe have developed a paper material called “Fine press” for use in paper tray and paper cup processing. The new paper can be squeeze processed to achieve “deep, strong and smooth” formation like that of plastic materials to produce trays and cups. Such processing is impossible using conventional paper.
We have discovered a way of improving a paper's forming capabilities by increasing the paper's breaking elongation ratio (the degree of elongation just before the paper breaks) against the stretching force applied during formation and also increasing the paper's compressibility.抄録全体を表示PDF形式でダウンロード (11205K) -

ジャーナル フリーWe describe the formation of microporous coating layers using a mechanical stirring method of introducing and dispersing air bubbles in resin-containing liquids. These microporous coating layers have been characterized in terms of their surface structure and optical property. The key technology in obtaining successful microporous layers is how to control the pore size of the microporous coating layers. Therefore, in our own research program, we have made intensive studies for obtaining a lot of fine air bubbles and stabilizing them in resin-containing liquids in order to obtain a large number of fine pores on the surface of the coating layers.
In the toner-based marking application, both non-printed and printed areas of the paper having microporous layer exhibit matte tone. There is little change of the gloss of the matte paper by increasing the solid fill area unlike a plain or pigment-coated paper. And print qualities and line qualities are improved and high quality picture is obtained.抄録全体を表示PDF形式でダウンロード (1740K) -

ジャーナル フリーChuetsu Pulp & Paper's Futatsuka Mill is located in the southern part of Takaoka City, Toyama Prefecture, rather peaceful area on the western side of the Shou River surrounded by the green farmlands where the Japanese Alps can be seen far away. Its main product being newsprint, The mill also produces printing paper, book paper, medium quality paper and bleached paper. The two paper machines, one 3, 800 min wide and the other 7, 300 mm, together produce 190, 000 tons of paper a year. 250 tons of TMP (thermo-mechanical pulp) and 360 tons of DIP (deinked pulp) are produced per day. KP (kraft pulp) is brought from Noumachi Mill in slush and lap. Some imported mechanical pulps is also mixed depending on the paper grades. We have two boilers and a steam turbine that generates 85% of the mill's required electricity.
We have continued to reinforce our environmental protection facility in accordance with the transitions of the production facilities. As for our activated sludge operation, when environmental matters became an issue in 1973, we built three 75 kW surface aeration systems to dispose 6, 400 kg per day of highly concentrated BOD effluent from the former CGP (chemical groundwood pulp) production system. Later the CGP system was replaced with the TMP system and the DIP system was installed. The production increased yearly which lead to the instability of the activated sludge operation. The Saturn and the Sun Jetter was installed to cope with this problem.We would like to particularly focus on the operations of Saturn hereinafter.抄録全体を表示PDF形式でダウンロード (3748K) -
