耐水性能 [机] hydrolytic resistance
- 通过粘度测定、粒度分析、力学性能和耐水性能测试、原子力显微镜(AFM)分析,研究了软段类型、软段分子量对乳液及其胶膜性能的影响。
The emulsion characteristics and properties of PU films were studied by means of rotational viscosimeter , Autosizer, tensile tester e and atomic force microscope (AFM). - 研究结果表明:中碱和抗碱玻璃纤维作为MDF水泥的增强材料具有较好的耐久性,并能显著提高MDF水泥的抗弯强度、断裂韧性和耐水性能;
The results show that, as a kind of strengthening material of MDF Cement, glass fiber not only have good durability but also obviously promote the bending strength, tenacity and water resistance. - 采用亚硫酸钠和三聚氰胺-尿素-甲醛预缩液对黑荆树单宁胶粘剂进行改性处理,制备具有良好的耐水性能和胶合性能的单宁胶粘剂。
The modification has been made on the black wattle tannin adhesive with sodium sulfite and the MUF concentrate so as to prepare out a tannin adhesive with good water-proof and better glue properties.
