In this paper a high temperature adhesive is introduced, which is mainly composed of phosphoric acid, metal oxide and additive. 介绍了一种高温胶粘剂,其主要由磷酸、金属氧化物及添加剂组成。
The Synthesis of Polycarboxylate Type Surfactants and its Fluid Mechanics Characteristics The properties of the phosphoric acid ester type surfactants, the process conditions for the synthesis reaction of phosphoric oxide with fatty alcohols and the influence of the different molecular structures on the product performances were discussed. 介绍了磷酸酯型表面活性剂特性、五氧化二磷与脂肪醇合成反应的一般工艺条件和不同分子结构对产品性能的影响。
But it is not appropriate for phosphoric acid electrolyte owing to its highly corrosive attack on the oxide film. Finally, PZT nanotubes were synthesized using a sol-gel method together with spin-coating technique in through-hole PAA templates. The effect of the PZT sol concentration was studied. 最后,采用溶胶-凝胶旋转涂敷法在一次恒流高场阳极氧化法制备的通孔PAA模板中合成PZT纳米管,研究了溶胶浓度对其形貌的影响。
