Effects of peregal O, sodium oleyl sulphate, sulphated castor oil, sodium methylene dinaphthyl sulphonate and casein on the structure and mechanical properties of natural rubber latex film have been studied.Experimental results show that the addition of stabilizer between 0.25-1.00 phr. at room temperature decreased the swelling in water, the amount of water extracts and the dielectric loss tangent to attain a minimum, but at the same time improved the mechanical properties and the shrinkage of the film to attain a maximum.By further increasing the film-forming temperature, the thermal movement as well as the increased solubility of stabilizer in the rubber caused the tight linking of the latex globules which decreased the swelling as well as improved the mechanical properties. On further vulcanizing the film it caused a little decrease in the swelling due to rapid crosslinking of the rubber molecules. It is suggested that the appearance of maximum or minimum on the property-stabilizer content curves is connected with the stability of the latex and the solubility of the stabilizer in the rubber.

本文通过测定胶膜在水中的溶胀度、水抽出物量、胶膜收缩率、物理机械性能以及介电损耗等,研究了平平加、十八烯基硫酸钠、蓖麻油硫酸钠、亚甲基二萘磺酸钠及酪素等五种常用稳定剂的不同用量,在不同成膜条件下,对胶膜结构及其性能的影响。并进一步探索了影响的原因。 实验结果表明:当稳定剂的用量在0.25—1.0之间时,水溶胀度、水抽出物量、介电损耗等均呈现极小值;而胶膜收缩率及物理机械性能等,则在以上相应位置有极大值出现。作者等主认为,极小值或极大值出现的原因,与胶乳的稳定性、胶乳粒子表面保护膜的性貭及稳定剂在橡胶中的溶解度有关。提高成膜温度,由于橡胶分子的热运动增大,同时稳定剂在橡胶中的溶解度也增加,故胶乳粒子结合比较紧密,物理性能亦相应增高。硫化处理时,由于橡胶分子间很快地形成交联,使分子失去扩散能力,故对胶乳粒子之间的结合及紧密度影响甚微。

本工作用化学法、超声法、X-射线分析法、热分析法以及电子显微镜观察等方法研究了酒石酸和CMC对C_3和C_3A的水化凝结机理,认为酒石酸主要通过提高水—C_3S高分散体系的动力稳定性使C_3S浆缓凝,CMC使C_3S浆体缓凝主要是由于水泥颗粒和新生成物表面吸附CMC大离子团而形成了保护膜的结果。因此酒酸对C_3S的缓凝作用较CMC显著得多,且能提高强度。酒石酸使C_3A促凝的原因是胶状新相的形成以及酒石酸极性分子促进铝胶的聚沉,CMC对C_3A的促凝作用是由于带负电的大离于团使水化体内铝胶聚沉加速。 在探讨缓凝机理的基础上,论文最后对缓凝水泥的矿物组成和缓凝剂的选择,以及有机外加剂对硅酸盐水泥的缓凝作用等问题提出了看法。

We computed, by using Mason's equivalent circuit, the acoustic waveforms radiated by thickness-mode piezoelectric circular transducers, possessing various structure parameters and being excited by a step voltage. We also computed the electrical waveforms produced by these transducers when they were used for receiving as well as for tansmitting, the radiated acoustic pulses being reflected by a plane boundary.

We computed, by using Mason's equivalent circuit, the acoustic waveforms radiated by thickness-mode piezoelectric circular transducers, possessing various structure parameters and being excited by a step voltage. We also computed the electrical waveforms produced by these transducers when they were used for receiving as well as for tansmitting, the radiated acoustic pulses being reflected by a plane boundary. Measurements were made with a thin measuring transducer at a close range in the first case or with the reflector also very close tothe transducer in the second case. On comparing the theoretical and the experimental results, it may be seen that in spite of the fact that Mason's equivalent circuit is a one-dimensional model, computed results are reasonably applicable. Some theoretically predicted details, such as the asymmetry of the radiated acoustic waveforms about the time axis, are experimentally confirmed. But then there remain some yet to be elucidated problems such as to what extent does the assumption hold that the radiated ultrasonic wave is plane.

我们采用梅森等效电路的方法,比较大量地计算了厚度模压电换能器在阶跃式电压的激励下,当具有一些不同的结构参数时,所发射的声波波形,或在又发又收时所产生的电信号波形。近距离的测量结果进行了对比。从对比结果看来,尽管梅森等效电路是相当简化了的模型,在我们所讨论的范围内,根据这个模型所得理论结果还是近似地可用的。这包括一些理论预计的细节,如辐射声波波形对于时间轴的不对称性。但也有些问题需要澄清,如辐射声波也是平面的这个假设的适用程度。 文内简单地涉及了保护膜厚度的改变将引起波形的畸变和声波频率的改变。也简单地涉及了关于接收电信号波形的先小后大或先大后小的控制问题。
