Problems solved by technology

The energy cost for heating and spinning process accounts for the main part of the production cost, and most of this energy consumption is just to maintain high temperature, and the energy is eventually lost and wasted
[0003] The composition of medium-alkali glass (C glass) defined by the Chinese building materials standard JC 935-2004 is: 66.5%-67.5% SiO 2 , 5.8-6.6wt% Al 2 o 3 , 9.2-9.8wt% CaO, 3.9-4.5wt% MgO, 11.6-12.4wt% R 2 O, where K 2 O≦0.4wt%, no more than 0.4wt% Fe2O3; C glass has acid resistance, but poor alkali resistance, because it contains alkali (R 2 O) is high, and alkali metal ions are easily precipitated in a humid environment to form an alkaline environment and further erode, greatly reducing its mechanical properties
[0004] The composition of alkali-resistant glass (AR glass) defined in the Chinese building materials standard JC 935-2004 is: 59.2-60.8wt% SiO2, not more than 1wt% Al2O3, 4.0-5.0wt% CaO, 13.9-16.1wt% R 2 O with 2.2-2.8 wt% K 2 O, no more than 0.5wt% Fe2O3, 5.5-6.5wt% TiO2, and 13.7-15.3wt% ZrO; AR glass has strong corrosion resistance, but due to the la

Abstract

The embodiments of the invention provide a fiberizable glass composition prepared from an ingredient composition. The ingredient composition comprises, but not limited to inorganic crystalline minerals, inorganic vitreous minerals, inorganic chemicals and the like.

Description

Field of invention: [0001] The present invention relates to glass compositions, and in particular to glass compositions for forming fibers. Background of the invention: [0002] Large-scale commercial production of continuous glass fibers involves melting batches consisting primarily of crystalline or non-crystalline minerals, followed by cooling and spinning. The part of energy cost for heating and spinning process accounts for the main part of the production cost, and most of this part of energy consumption is just to maintain high temperature, and the energy is eventually lost and wasted. [0003] The composition of medium-alkali glass (C glass) defined by the Chinese building materials standard JC 935-2004 is: 66.5%-67.5% SiO 2 , 5.8-6.6wt% Al 2 o 3 , 9.2-9.8wt% CaO, 3.9-4.5wt% MgO, 11.6-12.4wt% R 2 O, where K 2 O≦0.4wt%, no more than 0.4wt% Fe2O3; C glass has acid resistance, but poor alkali resistance, because it contains alkali (R 2 O) is high, and alkali metal ...
