Study on Preparation and Properties of Nitrile Rubber/ SiO_2 Composites High Performance Winding Clutch Friction Materials Based On Two Kinds Of NBR Emulsoid 丁腈橡胶/SiO2复合材料的制备及应用研究基于两种丁腈橡胶复合填料的高性能离合器摩擦材料
Taking VAE-707 as major raw material, re-dispersible emulsoid powder was prepared using airflow spray dryer. 以VAE乳液-707为主要原料,利用喷雾干燥设备制备了可再分散乳胶粉。
Methods The distribution of arteries and veins in fingers of4 hands from corpuses and6 hands from dead infants were observed after emulsoid infusion in blood vessels. 方法尸体手4只,死婴手6只,经乳胶血管灌注,观察手指的动脉、静脉分布。
The Determination of Emulsoid Particle ′ s Size and Weight Distribution of Core-shell 核壳结构聚合物乳液乳胶粒粒径及重量分布测试
The emulsoid resin operates the function of the resin as well as the role of the surfactant, which can improve the stability, water-repellency and glossiness quite available. 乳液树脂既起到树脂的作用又充当表面活性剂的角色,对提高稳定性、抗水性和光泽度都十分有效。
And the influences of monomer concentration, initiator, emulsifier, oil phase and temperature on emulsoid particle size, size distribution, the average relative molecular mass and so on were introduced in detail. 详细介绍了单体浓度、引发剂、乳化剂、油相、反应温度等因素对乳胶粒子粒径、粒径分布、聚合物平均相对分子质量等的影响;
Testing results showed that composites of soap-free emulsion with different inorganic powders displayed different water resistance and mechanical strength mainly due to the highly reactive carboxyls on the surface of the emulsoid particles. 测试的结果表明,无皂聚合的乳液与不同无机粉料的复合体具有不同的耐水性力学强度,这主要是由于乳液中胶体表面羧基的反应活性较高。
Application of redispersion emulsoid powder in cement mortar 可再分散乳胶粉在水泥砂浆中的应用
