1、Designation: D5359 98 (Reapproved 2015)Standard Specification forGlass Cullet Recovered from Waste for Use in Manufactureof Glass Fiber1This standard is issued under the fixed designation D5359; the number immediately following the designation indicates the year oforiginal adoption or, in the case o
2、f revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification describes glass cullet recovered frommunicipal waste destined for disposal.
3、 The recovered cullet isintended for use in the manufacture of glass fiber used forinsulation-type products.2.

General Requirements4.1 Glass cullet from municipal waste is primarily soda-lime bottle glass and shall be one of three
5、grades dependingupon the total usage rate requirement of the user. The threegrades shall satisfy the following chemical composition, colormix, contamination, and particle size requirements as listed inSection 4:4.2 Chemical CompositionSee Table 1.4.3 Color MixColor is an indicator of the oxidation s
6、tateof container cullet. SO3gas solubility in the glass melt is afunction of the glass oxidation state. Changes in the oxidationstate of cullet added to the fiberglass batch can shift the glassoxidation state causing the release of dissolved SO3gas, whichcan upset the furnace.Achange in the glass ox
7、idation state alsomeans a change in the glass FeO content. This affects the heattransfer in the melt and can affect furnace efficiency and glassquality. See Table 2.4.4 ContaminantsFree metals, magnetic or nonmagnetic,are not oxidized in the glass melting process and, therefore, areinsoluble. Metals
8、 will pool on the furnace floor and leakthrough joints causing premature wear of refractories andelectrical shorts, which can lead to glass leaks. Some metalswill attack and destroy precious metal skimmers and thermo-couples and molybdenum electrodes. Examples are silver, tin,lead, and aluminum.4.4.
9、1 Other inorganic materials and refractories will notmelt in the glass melting process. Other inorganics can beporcelains, ceramics, or high-temperature glasses. Refractoriescan be remnants of furnace construction materials or mineralscontained as unmelted inclusions in the cullet. See Table 3.4.4.1
10、.1 The container cullet mixture must not contain glasstypes or other materials whose composition contains anythingthat is either harmful to the fiberglass production process orwhich affects the users ability to meet Federal or stateenvironmental, safety, or health laws. Examples of suchmaterials are
11、 anything which contains elements or oxides ofphosphorus, arsenic, antimony, and chlorides.4.5 Particle SizeFor all grades of cullet, the particle sizeshall be 100 % 15%inbatchOxide Weight%Range%Weight%Range%Weight%Range%SiO26877 NA 6877 1.00 6877 1.00Al2O307 NA 07 0.50 07 0.50CaO 515 NA 515 0.50 51
