硅酸盐玻璃用混合原料以及使用该原料的管状玻璃的制造方法
摘要：
提供一种硅酸盐玻璃用混合原料以及使用该原料的管状玻璃的制造方法，能够抑制玻璃熔体表面所产生的非均质层的发展。本发明的玻璃用混合原料是至少含有硅砂和长石的硅酸盐玻璃用混合原料，其特征在于，该硅砂的D50值为100μm以上且300μm以下，用将D60值除以D10值而得到的值表示的均匀度小于2.0，该长石的D50值为100μm以上且400μm以下，用将D60值除以D10值而得到的值表示的均匀度为1.5以上且小于4.0。本发明还具有以下特征，将所述硅酸盐玻璃用混合原料熔融，并且成形为管状。
摘要（英）：

Provided is a mixed material for silicate glass and a method for manufacturing tube glass using the same such that the development of a heterogenous layer that is produced on a glassmelt surface can be suppressed. This mixed material for the silicate glass includes at least silica sand and feldspar, and is characterized in that: the silica sand has a D50 value of 100 to 300 [mu]m and uniformity represented by a D60 value divided by a D10 value of less than 2.0; and the feldspar has a D50 value of 100 to 400 [mu]m and uniformity represented by a D60 value divided by a D10 value of 1.5 or greater and less than 4.0. The mixed material for the silicate glass is also characterized in that the mixed material for the silicate glass is melted and formed into a tube shape.
