单片防火玻璃在欧美、日本地区发展较早,在中国的起步则是近几年的事。与传统的灌浆防火玻璃、复合防火玻璃相比,单片防火玻璃不仅强度高、通透感强,而且耐候性好,它的出现是防火玻璃行业的一场革命。2001年,随着GB15763.1——2001《建筑用安全玻璃防火玻璃》标准的颁布实施,单片防火玻璃逐渐被人们 相似文献

The mechanical properties and dimensional stability of hardwood aspen in the form of sawdust and surface-treated glass fiber-polystyrene composites were evaluated under various extreme conditions, e.g., variation in the testing temperature (from +25° to ?20°C), exposure to boiling water and heat in an oven at +105°C. The compatibility of wood fiber with glass fiber and with polystyrene improved by precoating the wood fiber with a coupling agent, e.g., 8% isocyanate, 4% silane and polymer. The mechanical properties of the composites, in particular, treated sawdust/glass fiber-filled composites, increased under extreme conditions in comparison with those filled with nontreated sawdust/glass fiber. Under the same conditions, dimensional stability also supports this observation. 相似文献

The ultraviolet transmission of Vycor brand glass No. 791 is compared with that of certain commercial glasses and fused silica. The loss in transmission after 230 hours of exposure to ultraviolet radiation (2537 a.u.) from a Hanovia arc was 2.5% for No. 791 glass and 32.5% for Pyrex brand glass No. 9741. The loss (approximately 12%), due to the darkened layer which forms on a glass surface in contact with a mercury arc, is smaller for No. 791 glass than for glasses in general. The decrease in 2537 a.u. output of experimental lamps was determined after operation times up to nearly 6000 hours; after 5000 hours, No. 791 glass showed 27% loss in hot cathode lamps and Pyrex brand No. 9741 showed 53%. Vycor brand glass No. 7911, developed for medium-pressure arcs (such as sunlamps), is discussed. The electrical properties of Vycor brand No. 791 are resistivity at 350°C., 9.2 (log R, ohm-cm.); loss factor at 1.0 mc., 0.00091; and dielectric constant, 3.8. 相似文献

Methods of fabricating sewn cloth with a low surface density made of glass fibres of different structures are examined. The
technological process according to scheme 2 is recommended in production of thread-sewn fibre glass cloth; untwisted glass
fibre or glass fibre with up to 30 tw./m can be used as the sewn material.

Considerable work has been published on the subject of filling reaction injection molded (RIM) polyurethane elastomers with discontinuous particulate fillers such as milled glass fibers, flake glass and wollastonite, RIM polyurethane elastomers are filled for three reasons: (1) to increase stiffness, (2) to decrease the linear coefficient of thermal expansion, and (3) to improve thermal dimensional stability. Discontinuous particulate fillers either do not appreciably change strength properties, e.g., tensile strength or they cause dramatic reduction in strength properties, e.g., impact resistance. To overcome these deficiencies, new fillers are necessary. Once such material is continuous glass strand mat. In order to make continuous glass strand-polyurethane composites by the RIM process, a particular balance of ingredients to produce the RIM polyurethane must be used. We will discuss the properties of these composites and suggest possible applications and future directions in which this research might proceed. 相似文献

采用熔融法制备了钛酸锶钡(barium strontium titanate,BST)基玻璃,然后将此玻璃样品在不同的温度下进行热处理得到BST基玻璃陶瓷,采用差热分析研究了BST基玻璃陶瓷析晶过程中的热力学特征,用扫描电子显微镜和X射线衍射分别分析了玻璃陶瓷的显微结构和相结构,并且系统研究了该玻璃陶瓷的介电特性以及耐击穿电场强度。结果表明:0.3%(质量分数)Ag+掺杂时,BST基玻璃中BST相的析晶温度从885℃下降到840℃,有利于玻璃体中BST晶体的析出。另外,Ag+的掺杂有利于提高BST基玻璃陶瓷的介电常数,同时能维持较低的介电损耗。此外,Ag+掺杂能够提高BST基玻璃的耐击穿电场强度,其在800℃热处理后,可达96.3 kV/mm,高于未掺杂Ag+的BST基玻璃的52.5kV/mm。 相似文献
