Methods and apparatus for recycling glass products using submerged combustion
RE046896 · 2018-06-19 · ·

A method for recycling glass mat waste, wound rovings, and other products includes providing a source of glass mat, or a plurality of rovings, for example on a roll, and routing the glass mat or rovings into a submerged combustion melter. An unwind system and a pair of powered nip rolls, powered conveyors, or other arrangement may work in combination to provide a substantially consistent rate of material into the melter. The melter may operate under less than atmospheric pressure to avoid fumes escaping the melter. A slot in the melter allows ingress of the glass mat or rovings into the melter, and a glass mat former such as a folder may be used to ensure that the mat fits through the slot. Alternatively, the glass mat may be cut by a slitter prior to entering the slot.

Glass Precursor Gel

A glass precursor gel and a method of making a glass product from the glass precursor gel are disclosed. The glass precursor gel includes a bulk amorphous oxide-based matrix that is homogeneously chemically mixed and includes 30 mol % to 90 wt.% silica and at least one of the following: (A) 0.1 mol % to 25 mol % of one or more alkali oxides in sum total, (B) 0.1 mol % to 25 mol % of one or more alkaline earth oxides in sum total, (C) 1 mol % to 20 mol % boric oxide, (D) 5 mol % to 80 mol % lead oxide, or (E) 0.1 mol % to 10 mol % aluminum oxide. A method of making a glass product from the glass precursor gel involves obtaining the glass precursor gel, melting the glass precursor gel into molten glass, and forming the molten glass into a glass product.
