| 摘 要： | 开发了离心自蔓延高温全成陶瓷内衬复合铜管制造工艺，研究了离心力和添加剂对复合铜管性能的影响。随着离心力增大，陶瓷层的孔隙度降低、压溃强度和压剪强度明显提高，离心力超过200G后，压剪强度反应而降低。铝热剂中加入SiO2也可降低孔隙度，提高压剪强度。提高铝热剂预热温度，可加快铝热反应速度，改善复合铜管质量。

| Abstract: | A new technology is proposed for the ceramic lining of a copper pipe inner surface by means of self-propagating high-temperature synthesis(SHS)under the influence of a centrifugal force and additives.The technique is characterized by a large amount of the reaction heat and the centrifugal force applied to the reaction products.With the increase of the centrifugal force,the porosity,the density the compressive strength and the compressive-shear strength of the products are improved,but centrifugal force excel 200G,the compressive-shear strength of the products is decreased.Adding SiO2 in thermite,the porosity,the density and the compressive-shear strength of the products are obviously improved.Increasing preheating temperature of thermite,the speed of thermite reactions quicken,the properties of products can also be improved. |
