ものである。Paper is currently used in a wide range of applications*, and is non-flammable or flame-retardant, with flexibility and tensile strength of 1%! There is a strong demand for the development of sheet paper. Traditionally, there have been non-combustible or flame-retardant papers such as mountain paper, asbestos paper, and fiber paper, but such non-combustible and flame-retardant paper! 1′! I (Burn paper has advantages and disadvantages, and currently there is no paper that has all of the above properties. For example, mountain paper has excellent flame retardancy and flexibility, but has low tensile strength, and asbestos paper Although it has excellent flammability and tensile strength, it has problems with flexibility, cracks occur on the surface when bent, and it is also expensive and undesirable from an environmental hygiene standpoint. Although fiber paper has excellent curling properties, it has problems such as low tensile strength and high cost.The above-mentioned chopped asbestos and fibers cannot be made into paper by themselves; Therefore, paper is formed by using inorganic or organic substances, but Yamahi has the excellent property of being able to form paper without adding any of these substances. .
