Patent number: 6284351Abstract: This invention describes two products both with a plain, fine textured, nonperforated surface visual consisting of a fiberboard substrate with or without a laminated porous nonwoven scrim and then a finished painted surface. The finish painted surface decorates or finishes the board, but most important, must remain acoustically transparent to retain the sound absorption properties of the fiberboard prior to painting. The fiberboard substrate is made to be porous or modified with hole perforations to cause it to be a good sound absorber. If the fiberboard substrate is sufficiently porous without hole perforations, then the sprayable, high solids, porous paint can be directly applied. If hole perforations are used to improve the sound absorption properties of the board substrate, then a porous, nonwoven scrim is attached and painted using the same high solids porous paint.Type: GrantFiled: March 24, 1999Date of Patent: September 4, 2001Assignee: Armstrong World Industries, Inc.Inventor: Darryl L.

Publication number: 20010018134Abstract: A moisture control construction material is enhanced in decorativeness and improved in stain-resistance by glazing the surfaces thereof. The material is prepared by mixing soil material and clay, molding the mixture to a body, applying glate on the body and firing the body. The body may be performed biscuit firing before glazing. The moisture-absorbing-and-desorbing-performance thereof in each 8-hour cycle is more than 80 g/m2. The body has prosity of 20-25%. More than 40% of pores of the body have a radius of less than 0.1 &mgr;m.Type: ApplicationFiled: April 11, 2001Publication date: August 30, 2001Inventors: Makoto Kotama, Hiroshi Fukumizu, Yukio Matsumoto, Masanari Toyama, Katsumi Yamamoto, Mitsunori Endo
