Title:
MOLDED INORGANIC-FIBER OBJECT AND PROCESS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2013/035645
Kind Code:
A1
Abstract:
Provided is a molded inorganic-fiber object which is characterized by being extremely lightweight, being reduced in flying of fibers or a particulate substance from the surface thereof, and being free from problems concerning environmental pollution, such as generation of a harmful substance. The molded object is excellent in terms of thermal shock resistance and mechanical shock resistance and of resistance to high-speed wind erosion, has an excellent balance among material properties, and can be used in various heat insulator applications.
The molded inorganic-fiber object comprises inorganic fibers and inorganic binder particles and has at least a pair of regions, a high-fiber-density region and a low-fiber-density region, wherein the ratio of the content of the binder particles in the high-fiber-density region to the content thereof in the low-fiber-density region, as determined by a given method, is 0.5:1 to 5:1 and the inorganic binder particles in the outermost surface of the molded object have a number-average particle diameter, as determined by a given method, of 20-35 µm, the number of the inorganic binder particles therein being less than 15.
