Title:
MANUFACTURE OF INORGANIC PLATE
Document Type and Number:
Japanese Patent JP3664886
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve surface formation and to make the surface smooth in a circulating plate-making process wherein a recycle material is used.
SOLUTION: In a manufacturing method according to this circulating plate- making process, a recycle material 2 is mixed in a cement material 3 and a fibrous material 1 so as to make a plate. In this case, the fibrous material 1 split by a pulper 11 is subjected to a treatment of wet type maceration 13 in the middle of a route for sending it, while the recycle material 2 is crushed 21 to be the powder of the maximum particle size 0.2-0.5 mm, and then the slurry of the fibrous material subjected to the wet type maceration and the powder of the recycle material are mixed with the cement material 3. Subsequently, the mixed slurry is passed through a slurry screen 43 of a 2-3 mm mesh to remove foreign substances and then the plate is made from the mixed slurry.
