摘要
本研究使用CelSian高温观测系统,对高铝硅酸盐玻璃的澄清过程进行了深入的分析;研究了澄清剂的种类和含量对澄清过程中气泡运动、气体吸收的影响。研究表明:对于不同种类的澄清剂而言,气泡逸出速率均会随澄清剂用量的增加而增大;而SnO_2的用量增加会使玻璃液对气泡的吸收率增大,NaCl和Na_2SO_4的作用则与SnO_2相反。澄清剂通过影响气泡的逸出和吸收,进而影响最终澄清效果。
High aluminosilicate glass melting and fining need elevated temperature too high for people to observe the complete process directly and make an analysis intuitively.In this paper,the CelSian high temperature observation system was used to carry out a thorough investigation of the fining process of high aluminosilicate glass with different types and dosages of fining agents,particularly the role in bubbles motion and gas absorption.Research shows that bubbles escape rate increases with the increase of dosage of fining agent for all fining agents added.With the increase of SnO2dosage the bubble absorption rate increases, whereas the effect of NaCl and Na2SO4 is contrary to SnO2.Fining agent makes melting glass finally fine through affecting the bubbles motion and absorption.
