HYDRAULIC INORGANIC MOLDED PRODUCT

PURPOSE:To obtain a highly durable product having both flexural strength and impact strength higher than those of conventional asbestos-incorporated products by using a combination of a specific PVA-based fibrous material as papermaking auxiliary and specific PVA- or PAN-based synthetic fibers as the main reinforcing fibers. CONSTITUTION:The inorganic molded product incorporated with (A) 0.5-5wt.%, on the whole solid basis, of a PVA-based fibrous material 200-550ml in freeness and >=80wt.% in swelling degree and (B) 0.5-3wt.%, on the whole solid basis, of PVA- or PAN-based fibers 0.3-20 denier in single fiber fineness, >=6g/de in tenacity and
