A tabular negative-pressure sheet 3 includes a baseplate 4, a sheet 5 with conduction grooves, a nonwoven cloth lamination outer layer 6, and a surface layer member 7. The baseplate 4 is a member as a base of the tabular negative-pressure sheet 3. In addition, the sheet 5 with conduction grooves is a member disposed on the outer side of the baseplate 4, and on the surface thereof, negative-pressure conduction grooves 8 are formed. In the tabular negative-pressure sheet 3, negative-pressure conduction grooves 8 are formed in a direction substantially perpendicular to a direction in which a strip 2 is threaded so that a negative pressure is generated as far as an end portion of the tabular negative-pressure sheet 3.

Since submission of this Phase II grant application, JDC has selected a site at the former Noralyn Mine beneficiation plant in Bartow, Florida for its research institute and follow-on demonstration plant. We are presently completing the business arrangements to lease and operate at this site. JDC will then move its office and laboratory to the Noralyn site where it plans to carry out significant parts of the Phase II program. Initially, the analytical labs used in the Phase I studies at XRL in Toronto, Canada, LECO labs in Michigan, and Agrium (Idaho) will be used for analysis of samples prepared at JDC. As the capability of the JDC lab is upgraded, more of the analytical determinations will be carried out there. The analytical measurements will be made using standard methods and the characterization of phosphate ore reserves for the IHP will be under the direction of a geologist using standard procedures. The analytical work for the Idaho reserves extension work will be carried out at the Agrium Laboratory. The characterization of the radon emanation and leaching characteristics of the co-product will be carried out at Pacific Northwest National Laboratories using standard analytical procedures and methods. The fish studies will be carried out in a certified commercial laboratory using standard procedures. The acquisition of permits and part of the engineering work will be carried out at the JDC labs at Noralyn. The engineering work will be partially carried out in New Jersey under the direction of Larry Handman (and support staff), who in addition to being on JDC staff is a licensed engineer and owns an engineering firm with all of the equipment required for professional engineering work. The vender testing will be under the direction of Bob Faulkner of JDC staff, mostly at the Metso process testing laboratories at Yorktown and Danville PA, which were also utilized in the Phase I program. The characterization of the radon emanation and leaching characteristics of the co-product will be carried out at Pacific Northwest National Laboratories using standard analytical procedures and methods. Modifications to the scrubber for phosphoric acid purity testing will be carried out under the design and construction oversight of a professional engineer at commercial fabrication facilities.

The negative pressure roll 1 is provided with a rotating shaft 2, an internal cylinder 3, an intermediate cylinder 4 and a multi-layered non-woven fabric laminated outer layer 5. Further, the rotating shaft 2 is a member at the center of rotation of the negative pressure roll 1 and connected to the internal cylinder 3 by a reinforcement circular disk 9. Still further, the internal cylinder 3 is formed in a tubular shape and rotates together with the rotating shaft 2. In addition, the rotating shaft 2 and the internal cylinder 3 correspond to a rotating main body. Further, the intermediate cylinder 4 is a cylindrical tubular material formed outside the internal cylinder 3 and rotates in association with the rotating shaft 2 and the internal cylinder 3. Still further, themulti-layered non-woven fabric laminated outer layer 5 is formed outside the intermediate cylinder 4 and given as a part at which the negative pressure roll 1 is in contact with the metal strip 13. The multi-layered non-woven fabric laminated outer layer 5 also rotates in association with the rotating shaft 2, the internal cylinder 3 and the intermediate cylinder 4. In addition, the negative pressure roll 1 is provided with a controller 6 for suppressing rotation of the negative pressure roll 1.

An absorption apparatus 1 that is an example of a loop amount absorption apparatus of a slitter line to which the present invention is applied is disposed in a region of a loop pit 3 provided in the slitter line 2. The absorption apparatus 1 includes a negative pressure roll 9 that grips and conveys strips and an up-down moving device 10 that enables the negative pressure roll 9 to move up and down. By gripping and conveying the strips 14 by the negative pressure roll 9, two loops 15 of the strips are formed. The negative pressure roll 9 includes a rotating shaft 16, an inner cylinder 17, an intermediate cylinder 18, and a non-woven fabric laminated outer layer 19.


There are provided an interlayer ion replacing method and an interlayer ion replacing apparatus which can efficiently replace the interlayer negative ions of hydrotalcite-like substances. The amount of positive ions which chemically-react with at least one of the interlayer negative ions or substituent negative ions is adjusted to facilitate desorption of the interlayer negative ions adsorbed by the hydrotalcite-like substances or to make the substituent negative ions easily adsorbed by the hydrotalcite-like substances, and the interlayer negative ions are replaced with the substituent negative ions.


A hydrotalcite-like substance capable of ion exchange with target anions, being of small crystal size that exhibits large basal spacing and excels at anion exchange performance; a process for producing the same; and a method of immobilizing hazardous substances. The hydrotalcite-like substance is produced by mixing an acidic solution containing aluminum and magnesium ions with an alkaline solution containing an alkali to synthesize a hydrotalcite-like substance, followed by, without ageing, water removal or neutralization. The molar ratio of aluminum ions and magnesium ions is preferably in the range of 1:5 to 1:2. Hazardous substances can be immobilized by pulverizing the hydrotalcite-like substance after synthesis and adding the powder to a subject, or adding a hydrotalcite-like substance in slurry form to a subject, or carrying out addition so as to cause the synthesis directly at the position of the subject. Furthermore, anion adsorption can be performed by a filter containing the hydrotalcite-like substance.
