Abstract

Forty Viscosity data of glass bottles fabricated in a glass bottle manufacturing plant for 4 years were calculated using Lakatos model. The relationship between the glass bottle compositions and viscosities at log η of 3, 6.6, 10 and 12.3 Pa·s was analyzed. MgO that was a component of the glass bottle showed the maximum coefficient of variation of 0.89, but it gave a very small change in the viscosity. CaO that was another component of the glass bottle lowered the isokom temperature because it tended to reduce the number of non-bridging oxygen at temperature below a softening point.

유리병 제조 공장에서 생산한 유리 조성을 4년간 40 차례 분석하여 Lakatos 모델로 점도를 구하였다. log η가 3, 6.6, 10, 12.3 Pa·s 일 경우의 isokom 온도를 구하여 조성과 isokom 온도와의 상관관계를 분석하였다. 조성에서 함량에 편차가 가장 큰 것은 MgO로 변동계수가 0.890이었다. 그러나 MgO 함량 편차가 점도 변화에 주는 영향은 제한적 이었다. 반면 CaO는 연화점 이하에서 비가교산소를 감소시키는 작용에 의하여 isokom 온도를 낮추고 있었다.
