Embodiment 1
[0040] A method for preparing alkali-resistant glass fibers from industrial waste modified by intermediate oxides and the prepared alkali-resistant glass fibers. The ingredients are as follows: The components and dosage are: red mud 9, blast furnace slag 21, quartz powder 52, industrial alumina 14, magnesium oxide 2.5, sodium oxide 1.5.
[0041] The experimental steps are: 1) Raw material pretreatment: Red mud is kept in a high-temperature furnace at 650°C for 170 minutes, blast furnace slag is kept in a high-temperature furnace at 310°C for 160 minutes, and then ground through a 200-mesh sieve. Other industrial raw materials are pretreated in 110°C was processed for 110 minutes to finally obtain a raw material with uniform and stable particle size and composition.
[0042] 2) Mixing: According to the ratio of raw materials, weigh each raw material and mix them evenly in a mortar.
[0043] 3) Melting: Heat the uniformly mixed batch materials in a high-temperature furnace to 1...
