乙氧基镁是低压聚乙烯催化剂的一种载体。我所测试站应用流动吸附法对其表面积进行了初步测试。测试装置主要由 BC—1型表面积测定仪和5毫伏量程的自动平衡记录仪组成。测试中采用 N_2气做吸附质,H_2气做载气。在实测乙氧基镁以前,对扩孔硅胶进行了测试,以考查测试装置的稳定性和能够达 Ethoxymagnesium is a carrier of low pressure polyethylene catalyst. My test station application of flow adsorption method on the surface area of ​​a preliminary test. The test set mainly consists of a BC-1 surface area analyzer and a 5 millivolt range autobalance recorder. N 2 gas was used as adsorbate in the test, and H 2 gas was used as carrier gas. Prior to the actual measurement of ethoxymagnesium, the expanding silica gel was tested to test the stability of the test device and to be able to reach
