装饰用平板玻璃生产所使用的模压辊

装饰雕刻玻璃已广泛用于各种建筑物中，它给人以高雅、庄重之感。采用模压成型雕刻技术，可以一次性生产出高质量产品，大大节约了生产成本。在我国，由于生产工艺和制造工艺水平的制约，此技术应用范围受到极大的限制，没有得到充分的利用。本文从以下几个方面来阐述模压辊的雕刻、装置及维护。1.雕刻要求用于装饰玻璃生产的模压辊的雕刻要求有高超的工艺。除了要求新颖雅致的设计图案之外，光折射率对成品的透光度也极为重要。浮雕的侧面效果必须达到：当从不同的方向观察成品时，既要有“塑胶效果”，又要有良好的透光效果。薄层雕刻的深…

Development of low-loss lead-germanate glass for mid-infrared fiber optics: I. glass preparation optimization

Reducing the mid-infrared attenuation loss due to absorption of hydroxyl (OH) groups and scattering of metallic Pb species for lead-germanate glass is essential to pave the way for their applications as low-loss mid-infrared fiber optics. In the first part of this study, we report the understanding of the factors that determine dehydration efficiency and metallic Pb formation during the lead-germanate glassmelting process. Combining a dry O₂-rich atmosphere containing ultra-dry N₂ together with the use of chloride dehydration agent and nitrate oxidation agent compound was found to enable efficient dehydration effect and absence of metallic Pb scattering sources in the dehydrated glasses. This glassmelting procedure overcomes previous limitations on the preparation of similar kinds of heavy-metal oxide glasses, where only pure O₂ atmosphere was used and/or use of fluoride dehydration agent deteriorated the glass thermal stability. This work provides guidance for developing other low-loss mid-infrared glasses/fibers containing multivalent heavy-metal ions such as Pb, Bi, Te, Sb, etc

Epoxy composites based on glass beads. II. Mechanical properties

A DGEBA/DDA network was used to study the toughening effect due to the introduction of glass beads with different volume fractions. The influence of surface treatment was also studied by comparing untreated, silane-treated glass beads, and beads coated with different thicknesses of an elastomeric adduct. The effect of the volume fraction of glass and the surface treatment were discussed in terms of elastic and plastic properties. The results were compared with the usual theoretical models. Linear elastic fracture mechanics and impact tests were performed to study the crack propagation process. The various parameters influenced the deformation mechanism, especially for the coated glass bead composites, for which an optimum thickness was displayed. A large improvement in G_Ic value was obtained with a slight decrease for the stiffness. © 1992 John Wiley & Sons, Inc.     

Tradition and experiment in first millennium a.d. glass production--the emergence of early Islamic glass technology in late antiquity

Following a brief history of analytical research into ancient glasses, the emergence of early Islamic glasses in the Middle East in late antiquity is discussed. Data sets for Roman and Byzantine glasses are compared to those of the early Islamic period. This is a rare period of technological transition when responses to the "drying up" of the traditional mineral alkali source resulted in experimentation, which can be demonstrated analytically.     

Epoxy composites based on glass beads. I. Viscoelastic properties

The viscoelastic behavior of glass beads composites are studied. Untreated, silane-treated and elastomer-coated glass beads were used, dispersed in a DGEBA–DDA–BDMA epoxy matrix. Using low frequency experiments, the three-phase structure of coated glass bead composites is demonstrated. The characteristics of both the α and β relaxations of the epoxy networks are analyzed and discussed. The β relaxation is independent of volume fraction and glass treatment. On the contrary, the position of the α relaxation increases strongly with glass volume fraction and silane treatment. The introduction of the elastomer as a thin layer at the filler/matrix interface induces a large chain mobility, thus decreasing the temperature position of the α peak. © 1992 John Wiley & Sons, Inc.     

Gel permeation chromatography using controlled-porosity glass. II. Polyacrylamide aqueous solutions

In a study of polyacrylamide in solutions we have required the rapid characterization on chromatographies. The application to the aqueous solution of the GPC using controlled-porosity glass has been examined from both the viewpoint of the effect of salt addition and the GPC mechanism. An adequate addition to neutral salt, 0.005M KCI to the eluent, gave rise to the elution behaviors being in accord with the hydrodynamic volume concept of the GPC separation.
