摘要:
A seal material or buffer material including inorganic fiber paper includes first biosoluble inorganic fibers having an average fiber diameter of 3µm to 7 µm, second biosoluble inorganic fibers having an average fiber diameter of 2µm to 3 µm, and a binder, the average fiber diameter of the second biosoluble inorganic fibers being smaller than that of the first biosoluble inorganic fibers, wherein the chemical composition of the second biosoluble inorganic fibers is different from that of the first biosoluble inorganic fibers, and the first biosoluble inorganic fibers are SiO 2 /CaO fibers having an SiO 2 content of 50 mass% to 82 mass%, a CaO content of 5 mass% to 34 mass% and an MgO content of 1 mass% or less, or SiO 2 /MgO fibers having an SiO 2 content of 50 mass% to 82 mass%, an MgO content of 1 mass% to 20 mass%, and a CaO content of 1 mass% to 9 mass%.

摘要:
The invention relates to a method for producing a phyllosilicate composition, comprising the following steps: contacting and treating a starting material during a treatment interval with at least one alkali metal salt, selected from the group consisting of chlorides, sulfates, phosphates, monohydrogen phosphates, dihydrogen phosphates, nitrates and mixtures thereof, and with sodium carbonate, the starting material being contacted with the sodium carbonate at the same time or after it has been contacted with the at least one alkali metal salt. The invention further relates to phyllosilicate compositions and uses thereof, and to a method for post-treating alkali-activated phyllosilicate compositions.
摘要:
To provide an inorganic fiber sheet with high workability, which is also excellent in tackiness or adhesiveness when a pressure-sensitive adhesive or an adhesive has been applied thereto. The inorganic fiber sheet is a non-woven fabric containing inorganic fibers. The inorganic fiber sheet has a thickness T of 1 mm or more and contains shots derived from inorganic fibers and having a diameter of 45 µm or more. The shots included in the inorganic fiber sheet is distributed in a sheet thickness direction as represented by Formula 1. Provided that Formula 1 is "1 - Y/X ≤ 0.11", where X represents "a total weight of the shots in the inorganic fiber sheet per unit area"/"a total weight of the inorganic fiber sheet per unit area", and Y represents "a weight of the shots per unit area included in the inorganic fiber sheet from which a portion having a thickness t and satisfying 0 ≤ t ≤ s is removed, provided, however, that 0.10 mm ≤ s ≤ 0.55 mm, with a wire side surface of the inorganic fiber sheet as a reference surface"/"a weight per unit area of the inorganic fiber sheet from which the portion having the thickness t is removed with the wire side surface of the inorganic fiber sheet as the reference surface".

Gravity-laid inorganic fiber webs and methods of making and using are disclosed. The gravity-laying process comprises mechanically separating inorganic fibers and collecting the fibers as a web, and may comprise blending of multiple types of inorganic fibers and/or blending of inorganic particulate additives with the fibers.
