example 1
[0062] 2.7 kg of annealed ceramic fiber (obtained under the trade designation "CERAFIBER" from Thermal Ceramics (Augusta, GA)) was slowly added to 189 liters (50 gallons) of water while using a low shear industrial mixer at about 400 rpm Minute speed for mixing. When all the fibers were dispersed and no clusters remained, 273 grams of latex (aqueous emulsion of ethylene vinyl acrylate terpolymer with 55% by weight solids, available from Air Products (Philadelphia, Pa.)). After the latex was added, 13.65 grams of polymer blend (50% solids; available under the trade designation "MP 9307C" from Mid South, Ringgold, LA) was added, followed by 17.3 grams of antifoam (available under the trade designation "FOAMASTER III") from Henkel in Germany). An additional 94.6 liters (25 gallons) of water were then added to the slurry.
[0063] About 38 liters (10 gallons) of the above slurry was pumped into the forming tank. Cylindrical preforms were prepared by dipping the screen side of ...
example 2
[0066] A second non-expanded cylinder was molded as described in Example 1. It was slid onto a ceramic monolith having an outer diameter of about 11.8 cm and a length of 15.2 cm until it was axially equidistant from both ends. The diameter of the monolith is about 2 mm smaller than the inner diameter of the mounting article.
[0067] A heat-shrinkable polyethylene tube having an inner diameter approximately 5 mm larger than the single piece of the wrapping mat and a width approximately 40 mm wider than the length of the mounting article was slid onto the mounting article. The mounting article is compressed onto the single piece using a heat gun to heat the film until the film shrinks tightly onto the mounting article. The mounting article is completely encapsulated by the film. The cylindrical mounting article is tightly fixed to the surface of the single piece and does not move relative to the single piece when the single piece surrounding the pad is dropped onto a tabletop...
example 3
[0069]6.4 kg of ceramic fiber (obtained from Unifrax Corp. (Niagara Falls, NY) under the trade designation "7000M") was slowly added to 210 liters (53.2 gallons) of water while utilizing a low shear industrial mixer at approximately 400 rpm Minute speed for mixing. While continuing to mix, the following materials were added in order: 114 grams of sodium aluminate (31.5% solids by weight), 2436 grams of latex (45.5% solids by weight; available from Rohm & Haas (Philadelphia, Pa. )), 36 g of defoamer (obtained under the trade designation "FOAMASTER III" from Henkel, Germany), 440 g of aluminum sulfate (50% solids by weight). Then 10.3 kg of unexpanded vermiculite (from Cometals Inc.) was added to the slurry and an additional 189 liters (50 gallons) of water were added.
[0070] About 38 liters (10 gallons) of the above slurry was pumped into a forming tank and a preform was formed as described in Example 1 except that the preform was kept in a drying oven at 150°C for about 3 h...
