论述工业水冷却塔验收评定测试主要热力性能参数,如水气质量比L/G、塔冷却数kav/L等的简明计算方法,以评定冷却塔原设计及改造后的能力。借经典湿球理论说明冷却塔的基本操作原理;借应用广泛的以焓差为推动力的迈克尔方程图解,比较原设计工况测试结果的性能。推荐的计算程序是美国冷却塔协会(CTI)规范要求,可免除现场测试数据经数学归纳推导出的经验关系式的繁锁与缺陷,使测试计算方法统一而规范. 相似文献

Synthetic cords may be coated with resorcinol formaldehyde latex (RFL)-based adhesives to adhere the cord to the rubber in industrial goods such as tires and conveyor belts. The stability of the adhesive and the stability of its component latex are crucial, both for ideal adhesion and for the homogeneity of the cord surface. Latex is a colloidal polymeric dispersion, which may lose its stability upon mechanical stress or upon interaction with some chemicals that lead to the formation of coagulated polymeric particles. This article reports on the influences of both external mechanical stresses and chemical interactions on RFL adhesives and latex stability, adhesion, and viscosity. High speed mixing, treatment with excess RF, and temperature variations were applied as disrupting parameters. 相似文献

The colloidal interactions of HASE associative polymers and latexes in the presence of surfactant are complicated and subject
to a number of variables. Both bridging and depletion flocculation can occur, in addition to good particle dispersion. Dispersion
phase diagrams have been developed to help visualize these interactions. The various dispersion states can have a significant
effect on coating formulations and film properties. Examples of dispersion phase diagrams are presented for a model HASE anionic
associative thickener and various model latexes in the presence of sodium dodecyl-sulfate and nonionic surfactants. The major
variables affecting dispersion behavior are associative polymer concentration, latex particle size, latex surface hydrophobicity,
electrolyte concentration, and surfactant concentration. The dispersion phase behavior of the HASE systems is compared to
that of HEUR thickened systems reported previously. A significant difference is that much less bridging flocculation is observed
in the HASE systems. In addition, nonionic surfactants induced depletion flocculation in the HASE systems but not in the HEUR
systems. 相似文献
