A furnace formerly used in glassmaking for calcination of materials into ''.

熔炉一种以前用在玻璃生产中的火炉,用于原料到玻璃质的锻烧

Raffinose, stachyose, and Galpi were found to have good glass forming properties, and their glass transition temperatures were 67.4, 66.4, and 33.40℃, respectively.

棉子糖、水苏糖和甲基肌醇半乳吡喃糖有良好的玻璃质化特性,其玻璃质化转移温度分别为67.4、66.4和33.4℃。

The Tg for a mass ratio mixture of Galpi and sucrose of 0.3/1 was greater than 0 and was similar to that of the same ratio mixture of raffinose to sucrose, indicating that Galpi as well as oligosaccharides plays an important role in glass formation.

甲基肌醇半乳吡喃糖和蔗糖以0.3对1重量浓度混合比例,其玻璃质化转移温度在0℃以上,且近似於相同比例之寡糖类和蔗糖混合,显示甲基肌醇半乳吡喃糖和寡糖类在玻璃质化形成上扮演重要的角色。

Discharge valve: glass-lined equipment is high in silicon content of the vitreous enamel.

3, 放料阀:搪玻璃设备是含高硅量的玻璃质釉。

A: They are usually caused by a clumping of pre-existing vitreous fibers in the eye.

通常是由存在眼中的从状的玻璃质的纤维导致的。

Results of meausred radioluminescence spectra show that energy transfer mechanisms occurring from Gd3+ cations towards Tb3+ emssion centers as well as the cross relaxation among Tb3+ cations within the certain concentration range exert tremendous effects on the emission intensity of glasses.

Tb3+离子的掺杂浓度范围为1-5 mol %。玻璃样品的X射线激发发射光谱结果显示,发生在玻璃基质中由Gd3+离子向发光中心Tb3+离子的能量转移机制以及在一定浓度范围内Tb3+离子之间的交叉驰豫过程对玻璃的发光性能有重要影响。

Firstly the oxidation loss was controlled by the reaction between the coated C/C composites and oxygen. Secondly the oxidation loss was controlled by the producing and vaporing rate of the glass. The oxidation loss was lined with the oxidation time. Thirdly there were cracks in the coating and the deep of the coating was oxidated. The weight loss rate increased linearly and the matrix had been oxidated partly in the end.

氧化初期,涂层的表面开始氧化,氧化失重是一个受氧气和涂层的化学反应控制,表现为氧化增重;氧化中期,氧化失重受玻璃质的形成速度和蒸发速度控制,表现为缓慢的氧化失重,氧化失重与时间的关系为直线型;随后,涂层上出现裂纹的形成和愈合过程,涂层深层被氧化,表现为较快的氧化失重;最后,涂层被局部破坏,基体被部分氧化,氧化失重直线上升。

The weight percentage for the components of the hyaline coating is as follows: SiO2 45 to 54 percent, B2O3 15 to 20 percent, one or more of Na2O, K2O and Li2O, 10 to 24 percent, one or more of TiO2, ZrO2 and ZnO, 6 to 18 percent , and the rest is one or more of CaO, MgO and CeO2. Firstly, the glass powder is mixed with the mill additions to be pulped and then plated on the surface of titanium or the titanium alloy. After being dried, the surface of titanium or the titanium alloy is directly used for a thermal hydrogen treatment or smelted at a temperature of 900 to 1, 000 DEG C for 15 to 30 minutes and then a hyaline coating with a thickness of 20 to 70 micrometers is formed on the surface of titanium or the titanium alloy; secondly, titanium or the titanium alloy plated with the coating is conducted a thermal hydrogen treatment. After the treatment technique is finished, the coating flakes off automatically in the process of cooling; and finally, a surface treatment is supplemented to meet the requirement of the workpiece surface.

该玻璃质涂层成分按重量百分比:45-54SiO2,15-20B2O3,10-24Na2O、K2O、Li2O中的一种或多种,6-18TiO2、ZrO2、ZnO中的一种或多种,余量CaO、MgO、CeO2一种或多种,将玻璃粉与磨加物混合制浆并涂覆在钛或钛合金表面,干燥后直接用于热氢处理,或在900-1000℃下熔烧15-30min,在钛或钛合金表面制得20-70微米玻璃质涂层,随后将制有该涂层的钛或钛合金置于氢气气氛下进行热氢处理,处理工艺结束后,涂层在冷却过程中自剥落,最后辅以表面处理即可满足工件表面要求。

Study it is tall purity, OK to fight eroded vitreous kiln to use actor * qualitative silica brick so the service life that prolongs vitreous kiln on certain level. 1 experiment develops vitreous kiln to be handpick and high grade raw material with the main avenue of high grade silica brick, the purity; that the alkalescent oxide content that in reducing raw material, takes will come to raise silica brick deserves to compare through adjusting raw material grain, apparent pore is reduced to lead when shaping in order to raise compact sex, achieve fight erode the effect.

所以探究高纯度、抗侵蚀的玻璃窑用优*质硅砖就可以在一定程度上延长玻璃窑的使用寿命。1试验研制玻璃窑用优质硅砖的主要途径为精选优质原料,降低原料中带入的碱性氧化物含量来提高硅砖的纯度;通过调整原料颗粒配比,成型时降低显气孔率以提高致密性,达到抗侵蚀效果。

Therefore, doctors usually refer to them as vitreous condensations.

因此,医生也称之为玻璃质的凝固
