Effect of concentration of silane coupling agent on bonding strength of barium glass to resin matrix 硅烷偶联剂的浓度对钡玻璃与树脂基质间粘接强度的影响
The effect of composition on the tendency of forming BAS ( barium aluminosilicate) sintered glass with compositions near the theoretical composition of barium feldspar by sol-gel process was studied by XRD, SEM and Raman spectrum. 采用XRD、SEM和拉曼光谱研究了溶胶-凝胶法制备的接近钡长石化学计量成分的BaO-Al2O3-SiO2系烧结玻璃形成趋势。
The main ingredients used in the manufacture of glass at that time were silicon dioxide, together with small quantities of lead and barium and so this locally produced Pb-Ba glass was quite different to the Na-Ca glass produced in the West. 其时玻璃的主要成分为二氧化硅,并含有少量铅、钡,故称为铅钡玻璃,与西方钠钙玻璃不同而独树一帜。

Colloidal barium ferrite and colloidal PSS ( poly sodium 4-styrenesulfonate) were prepared and a nano multi-layers film of A/ B type was formed on the surface of glass plate by electrostatic self-assembly. 配制了钡铁氧体和PSS(polysodium4styrenesulfonate)溶胶,并利用静电自组装的方法在普通玻璃板上组装了A/B型纳米多层膜。
Conclusions: The absorption behavior of a silane coupling agent γ-MPS was revealed on the barium glass surface, which provided the theoretical basis for the development of dental composite resins. 结论:揭示了硅烷偶联剂γ-MPS在钡玻璃表面的吸附特征,为新型复合树脂的研究和开发提供理论依据。
Results: When the concentration of γ-MPS was low, the γ-MPS molecules oriented either parallel or perpendicularly onto the barium glass surface. 结果:γ-MPS低浓度时,分子在钡玻璃表面的吸附既有垂直取向又有平行取向;
Each γ-MPS molecule occupied 0.21 nm~ 2 when the monomolecular coverage was formed on the barium glass surface. γ-MPS在钡玻璃表面单分子层覆盖所占据的面积为每分子0·21nm2。
Results The relationship tallied with negative linear correlation between the K-M function values of the isolated OH-groups on the barium glass surface and the concentrations of γ-MPS. 结果钡玻璃表面游离羟基的K-M函数值与γ-MPS质量分数存在负相关的直线相关关系。
This kind of materials is made from barium glass fibre and epoxy resin, solidified at atmospheric temperature, well transparent, sensitive in photoelastic effect, and simple in procedure. It is suitable to make two-dimensional and three-dimensional photoelastic models of composite materials. 这种材料用防辐射玻璃纤维和环氧树脂经常温固化制成,其透明度好,光弹性效应灵敏,制作工艺简便,适于制作二维和三维复合材料光弹性模型。
