SLIP SHEET FOR CERAMIC SIDING MATERIAL AND METHOD FOR LAMINATING CERAMIC SIDING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a slip sheet which leaves no mark for a ceramic siding material and a method for laminating the ceramic siding materials using the same. SOLUTION: The slip sheet for ceramic siding materials includes a surface having center line average roughness Ra defined in the JISB0601 of 0.2 μm or more and the maximum height Rmax of 4 μm or more. Further, the slip sheet preferably has at least one of its surfaces occupied by a surface having the center line average roughness Ra defined in the JISB0601 of 0.2 μm or more and the maximum height Rmax of 4 μm by 40% or more. In addition, a method for laminating the ceramic siding materials uses such slip sheets between layers of the ceramic siding materials.
