Sticking temperature of glass and molds

Tribological investigations of the glass‐to‐metal contact during glass forming at an industrial scale

“…The theoretical framework of the present study is based on investigations done by ALEKSENNKO, ABRAMOVICH and KALASHNIKOV and later FALIPOU (14)(15)(16). One additional aspect of glass forming refers to the sticking of the glass to the contact material.…”

“…One additional aspect of glass forming refers to the sticking of the glass to the contact material. The corresponding theory is nowadays mostly accepted, being based on the hypothesis for sticking [1], [13][14][15]. It states that a viscoelastic glass melt starts to stick to the contact material at an interface viscosity of 10 8.8 Pa•s, regardless of the contact material.…”

“…The corresponding theory is nowadays mostly accepted, being based on the hypothesis for sticking. 1,[13][14][15] It states that a viscoelastic glass melt starts to stick to the contact material at an interface viscosity of 10 8.8 Pa•s, regardless of the contact material. Hence, the sticking temperature of a glass only depends on two factors, i) on its chemical composition which determines the respective temperature at which the critical sticking viscosity is reached and ii) on the thermal effusivity b of the respective contact material.…”
