2.Optimizing Technological Parameters of Preparation of Bi Nanoparticles by Orthogonal Experimental Method
5.A method for preparation of brominated polystyrene using EDC as the reaction medium is reported. A bromination reagent BrCl and a lewis acid catalyst (AlCl3) were used. The best technological conditions for preparation of brominated PS were found by the experiments.
6.The preparation of soudium carboxymethyl cellulose (CMC Na) from chloroacetic acid and iso propyl chloroacetate was studied. Some factors influencing on preparing process were discussed. The optimum technological conditions of the preparation of CMC Na were obtained.
7.Technological Investigation of Co -Nitration Process for the Preparation of NG/BTTN Nitrate Ester Mixtures
8.During the process for production of inositol, the technological parameters and operation methods in several stages of preparation, acidolysis, neutralization, ion exchange and refining are very important factors influencing the quality and yield of products.
9.This paper introduces the main preparation methods of nickel hydroxide used as positive pole material,as well as the technological conditions and major characteristics of the methods. The main factors which affect the preparation of Ni(OH)_2 are described. The nickel hydroxide has a bright future to used as positive pole material, but its preparation technology needs further study.
10.Debugging process, preparation before debugging, technological work before shifting to production,debugging method and application of CAE in mold design and debug were all discussed.
