ジャーナル フリーDeterioration of books has stormed libraries, archives and museum of the world. This paper treats the problem briefly. Studies on book preservation have been performed in the United States prior to studies in other countries, while it is at the dawn in this country. Attention to the degradation of books and archives is paid little in Japan because of the wide spread of the Japanese hand-made paper until twentieth century. Japnese hand-made paper has the longevity of over 1250 years. Much results revealed that the degradation of paper was brought about by the acidity of paper.
In addition to the acid hydrolysis, the degradation mechanism of paper was reviewed in terms of the molecular structure of cellulose. Neutral sized-paper is recommended for the preservation of book.抄録全体を表示PDF形式でダウンロード (1384K) -

ジャーナル フリーNew recovery boiler (350T-KP/D) was installed March, 1983 at Yonago mill of Oji Paper Co., Ltd.
The boiler is designed at high pressure and high temperature (100 kg/cm3 × 500 °C) dy recent technology.
The good points of this boiler are high reduction efficiency, high thermal efficiency, low pollutants emission, long term continuous operaion, easy operation and so on.抄録全体を表示PDF形式でダウンロード (1097K) -

ジャーナル フリーJapan Pulp & Paper Research Institute Inc. has just begun the study on process development of Solvolysis pulping. The study is financially supported by Ministry of International Trade and Industry and will be continued for the period of five years.
In this report, the present state of kraft pulping is discussed from the viewpoint of wood or biomass utilization and other alternatives including Solvolysis are outlined.抄録全体を表示PDF形式でダウンロード (921K) -

ジャーナル フリーThe #9 paper machine at Tomioka Mill was put into commercial operation in March 1980. This paper machine, comprising a wire part of Valmet Sym-Former F which was the first experience in Japan at that time, Produces 240 metric tons daily of bace stock for lightweight coated paper with a maximum speed of 850 meters per minute. The twin-wire machine was also new to Kanzaki. We would like here to introduce some of our experiences with the Steady flow nozzle and Sym-Former F. based on our 3 years' operation.抄録全体を表示PDF形式でダウンロード (504K) -

ジャーナル フリーLast year the Mitsubishi paper mills Hachinohe mill completed the rebuild of headboxes of No. 2 and No. 3 paper machine for sheet formations and CD profiles improve. No. 2 and No. 3 machine produce printing and coated base paper grades.
The adopted new headboxes are “Thin-channel headbox” by Beloit-Mitsubishi Heavy Industries.
To minimize downtime for the rebuild, a significant amount of work was done before the machine shut down, so startup of the machine was 4 days and 6 days in No. 2 and No. 3 machine respectively.
As a result of the rebuild, both machine can produce good sheet formation and good CD profile webs.
In addition, the strength of the paper (Tensile, Tear and Internal bond strength) can increase.抄録全体を表示PDF形式でダウンロード (556K) -

ジャーナル フリーWe, engaging in paper industry, have invariable and common aiming of manufacturing “good paper”.
The definition of “good paper” is argued from among quality, pricing and both points depending upon its circumstances.
Now in this paper, one of the technical factors during paper making is described.
In the case of operating Fourdrinier paper machine, the hydraulic behavior of stock on the wire is considered as one of the most crucial factors of paper making. However, it is impossible to grasp those phenomena precisely through our naked eyes. Even those quickly-passed and non-reproducible phenomena can be grasped more scientifically and more concretely in the so-called static phase of 1/30, 0001/50, 000 second.
Those photos together with various operational data, test data of paper properties & surface roughness, photos of two sidedness, photos of fiber orientation & distribution and basis weight/moisture profile, are analysed in the panoramic view, which are considered rather effective method for self-consultation of operation.抄録全体を表示PDF形式でダウンロード (20413K) -

ジャーナル フリーIn this paper with the intention of establishing the high consistency paper making and high efficiency drying process, it became clear that :
1) The rotation viscometer made for investigating the flow behavior of pulp suspension was available for studying the dependency of pulp suspension on the shear stress.
2) It was confirmed that the geometrical structure and properties of paper formed in high consistency (obtained from Ahlström Oy.) was different from the usual as regards bulky structure, higher Z-strength and lower tensile strength.
3) Investigating the pulp dispersion in various head boxes and ducts by means of optical measurement and/or stroboscopic photography chose the better dispersing devices out of them.
4) The refloculation of pulp fibers within several tens microseconds required the instantaneous consolidation in process of sheet formation in 3% pulp suspension.
5) By using the modified existing screen reducing cut width and increasing agitator speed, dusting was possible in 3% pulp suspension. Anxious pulsation was not observed.
6) The differences in viscosities and dispersions of various pulps reduced with increasing shear rate in rotation viscometer.
7) Among the factors affecting drying rate, important were the diminished pressure of water vapor, roughness of dryer plate and the pressure applied on wet sheet.
8) Measuring the heat insulating of dryer pannel joint resulted in replacing the aluminium of inner plate by better insulating material.抄録全体を表示PDF形式でダウンロード (27302K)
