摘要:
An apparatus and method for the preferably continuous manufacture of foamed material (16) using a furnace (14) are provided. A two-part mold mechanism (11) is provided that includes an upper portion (12) and a lower portion (13) that are each endless loops (17, 18) and cooperate with one another to form a closed mold within the furnace (14). The upper and lower portions (12, 13) can each comprise a plurality of transverse mold members that can be easily replaced or exchanged during operation of the apparatus (10). A feed mechanism (15) is provided for introducing material (28) that is to be foamed to the mold mechanism (11) upstream of the furnace (14). Scrapers (32) or the like can be provided downstream of the furnace (14) to aid in separating and supporting foamed material (16) from the mold mechanism (11).

摘要:
A foamed glass article for preparing surfaces, the use therefor, and a method of making same are provided. The foamed glass article is in the form of a block, disk or similar product, and is used for preparing surfaces such as by sanding, rubbing and scraping the same to clean, abrade, polish, smooth, or the like such a surface. The foamed glass article is formed from a starting mixture that comprised waste glass, 0.10-20 % by weight of a non-sulfur based foaming agent, and optionally an additional abrasive material. A mixture of powdered waste glass and non-sulfur based foaming agent can be placed in a mold and heated so that the mixture sinters and subsequently foams. Thereafter, the foamed mixture is annealed.
