Module Jet HeadboxOsamu Yasui1995 Volume 49 Issue 1 Pages 60-63
Published: January 01, 1995
Released on J-STAGE: November 16, 2009
JOURNAL FREE ACCESSIHI-VOITH has developed a new headbox with Module Jet. In this new headbox, the CD basis weight profile is controlled by locally changing the stock consistency across the machine width. The conventional headbox depends on their adjustable slice lip to control it, therefore the fiber orientation profile is changed accordingly. Only Module Jet can control the CD basis weight profile and the fiber orientation profile independently.
Module Jet is better applied to gap former headbox and multi-layer headbox because of its simple top lip structure.
The first Module Jet successfully started up at Munkedal PM 5 (Sweden) in January 1994, and then the order of Module Jet has been 15 units.View full abstractDownload PDF (8145K) -

JOURNAL FREE ACCESSIt was introduced in the 1993 edition of “FADUM REPORT” that ABB/AccuRay Smart Color Sensor and Color Control System was able to only give the best color measurement and control system for paper machine application among the suppliers who had provided color sensor and control system.
AccuRay Smart Color Sensor with high accuracy and high Inter Instrument Agreement and Color Control help to eliminate color difference between top and bottom surfaces and give stabler color quality on a paper making process. Furthermore, AccuRay Color Control can be adapted to various paper operating conditions, and the control performance is improved by the unique color dye calibration technique in applying to various color shades with variety of color dyes.
The actual use of the Smart Color Sensor and Control System for multi color application in Japan has given the excellent results of stabler color quality, minimizing shade change time and saving usage of color dye. By using AccuRay color control, machine tenders, who are not expert of color/dye, was able to get color matching and shade change with ease of work.View full abstractDownload PDF (795K) -

JOURNAL FREE ACCESSA gas turbine power plant was introduced into Niigata Mill in Hokuestu Paper Mills Ltd. in 1993 in order to reduce energy cost. Our operating experiences over about 1 year are described in this paper. This power plant enable us to obtain an independent electric power production source in such a short period.
We adopted the state of the art heavy-duty and hight temperature, which enabled us to recover steam with a high temperature and pressure. In addition, by utilizing an existing steam turbine plant efficiently, the mill energy cost could be lowered successfully.View full abstractDownload PDF (998K) -

JOURNAL FREE ACCESSDeinking Technology has been rapidly improved specially in the field of hardware, such as High Consistency Pulping, Fine Slot Screening, Dispersing, and Post-Flotation etc.. However Almost all of the deinking process are still operated under Alkali base, which is still common technology for the deinking.
In order to improve sticky problems, Aikawa has recommended two loops deinking system which consists of Neutral, Room Temperature loop for the first half of the system and Alkali, High Temperature loop for the latter half of the system since several years ago. In Europe, very recently, the first Neutral deinging system was started in an actual paper mill, which shows some advantages to protect the pollution of environment and to save production cost in spite of some disadvantages. This paper shows these advantages and problems for the Neutral Deinking Technology.View full abstractDownload PDF (19143K) -

JOURNAL FREE ACCESSRecycling of white grade waste-paper is one of the important criteria in paper recycling. The fiber length distribution of the deinked pulp is very similar to that of hardwood bleached Kraft pulp (L-BKP). The ink was efficiently removed during flotation process and the brightness of the pulp was about 80% after final washing. The strengths of pulp are lower than that of L-BKP but it is strong enough to blend this pulp to various grades. This plant is also equipped with white water treatment device which allows the less fresh water usage for whole process.View full abstractDownload PDF (561K) -

JOURNAL FREE ACCESSPrior to 1988, the Suzukawa Mill of Daishowa Paper Manufacturing Company Limited had three causticizing lines. In 1988, two of these lines were phased out and replaced by one new line designed by AHLSTROWM Limited.
This project was undertaken to improve the productivity and cost effectiveness of the causticizing operation. The white liquor capacity of the new line is 4, 300 m3 per day and the newly-installed 106 meter kiln has a calcination capacity of 350 tonnes per day.
The new line is controlled by a fuzzy logic control system supplied by F. L. S. Japan. Daishowa regards the installation as highly successful in recognition of its 5 years of stable operation.
This paper covers the operating parameters of the new causticizing line and the fuzzy logic control system. Also discussed are the importance of lime mud quality control and the challenge of control of scale in the system.View full abstractDownload PDF (1118K) -

JOURNAL FREE ACCESSCENIBRA produces approximately 350, 000 ADT/year of bleached eucalyptus kraft pulp at their mill in the State of Minas Gerais, Brazil, and all of their pulpwood is supplied by their company-owned eucalyptus forests of which the regular cutting period is seven years. The area of the company-owned forests is about 156, 000 ha as of January of 1994, out of which about 88, 000 ha is a planting area with 89.6% of E. grandis.
The planting area occupies only the 50% level of the forest, because the protection of environment has resulted in leaving 20% of the forests as a forest reserve and in addition the forests located in the shores of rivers, lakes and swamps, and slopes as an eternally reserved forests. Also thoughtful consideration has been taken on native species of trees, birds and so on. Now, afforestation and environment protection has become an very important issue inseparable as Siamese twins.View full abstractDownload PDF (884K) -

JOURNAL FREE ACCESSThe present status of high performance papers, i. e., engineered papers, advanced papers, highly processed papers that are being produced in Japan are overviewed in this report. A comprehensive survey of highly value-added papers was conducted by High Performance Paper Society and its report was published recently. The function of these papers were classified into ten categories. As for merchandised high performance papers, the top three in descending order are heat-resisting paper, electrical insulating paper, adhesive and released paper.
For merchandising high performance papers, their R & D have to be knowledge-intensive as well as technology-intensive. Since the market size is limited, the companies producing high performance papers should concentrate on their own fields. To strengthen the companies's competitiveness and to make globally inroads into overseas markets, it is desirable to form a production complex of high performance papers. The future development of high performance papers should go along with the notion of “earth friendly”.View full abstractDownload PDF (3159K) -

JOURNAL FREE ACCESSOne of the most significant advance in fine paper forming has been the shift from fourdriniers to hybrid formers, which enable curl and formation to be much better controlled than on fourdriniers. But both fourdrinier and hybrid formers suffer from free surface instabilities which increase with speed. Paper quality and runnability often start to suffer at speeds lower than their limitations.
On the other hand, Gap formers have been used for news and specialty fine paper grades because of higher speed potential and better control of curl than hybrid formers. However, gap formers have limitations of paper grades owing to limited drainage capacity.
This paper will introduce “Speed-Former MB”, which has been developed as the latest roll and blade gap former concept to obtain the best solution for much improved fine paper forming.View full abstractDownload PDF (9918K) -
