The microscopic appearance of flexibilizer FR in cement is observed by SEM and also the distribution and bounding of the fiber in cement. 借助扫描电镜对油井水泥增韧剂FR的微观形貌,纤维在水泥石中的分布及纤维与水泥基体的粘结情况进行了观察。
The properties of compression strength, bending strength, tensile strength, binding strength and elastic modulus of epoxy mortar modified with flexibilizer and fiber have been studied. 研究了掺增韧剂和纤维进行改性的环氧砂浆抗压、抗弯、抗拉、粘结及弹性模量等性能。
SY 24B film adhesive has better toughness than SY H2 paste adhesive, but the latter has better shear fatigue and creep properties. Difference of the two adhesives is relevant with flexibilizer and bondline thickness. SY24B胶膜虽然具有优异的韧性,但SYH2糊状胶粘剂的剪切疲劳和蠕变性能优于SY24B胶膜,这与增韧剂种类与胶层厚度有一定关系。
The article introduces the formula of AC structure adhesive whose properties can be affected by curing agent, flexibilizer and filler. 本文主要介绍了AC建筑结构粘合剂的配方、粘接性能、固化剂、增韧剂、填料对粘合剂性能的影响。它是一种建筑结构加固胶。
The effectiveness of SiO2 and SBS content to the strength and toughness of blends is investigated using SiO2 as packing and SBS as flexibilizer. 以SiO2为填料,丁苯橡胶(SBS)为增韧剂,探讨SiO2、丁苯橡胶含量对共混体系强度、韧性的影响。
The results showed as follow: 1. Polyvinyl acetate, used as a flexibilizer, can increase the flexibility of SN-decorative laminate and decrease the water resistance of it; 聚醋酸乙烯酯作增韧剂,能提高装饰板的柔韧性,但装饰板的耐水浸能力大为通下降;
The mechanical tests approve those results: the flexibilizer FR can increase cement's toughness remarkably. 试验结果证实:油井水泥增韧剂FR的增韧效果显著;
In order to characterize the properties of flexibilizer of oil well ( named FR), the cement's mechanical performance and cement slurry's engineering performance are tested and compared with a plasticizer for oil well cement ( named S). 本文力图从油井水泥石的力学性能及水泥浆体的工程性能两方面表征油井水泥增韧剂FR的性能,并与国内某品牌的油井水泥增塑剂S进行比较。
