If the production system has several routes, material flows, it is necessary to formulate shipping matrix for individual materials flows and routes.
Shipping by carriage enables material transfer between production sells.

Shangyu 312368, P.R.China aemail: liangfei662003@foxmail.com bemail: zhongbei232@qq.com Keywords: Waterborne Polyurethane; Emulsion; Synthesis; Property; Printing Ink Abstract: Taking polyether dihydroxy alcohol, toluene diisocyanate (TDI) and dimethylolpr- opionic acid (DMPA) as raw materials, aromatic polyether waterborne polyurethane emulsion was synthesized.
In this trend, water-based polyurethane of pollution-free green materials should be developed, which will achieve good economic and social benefits [2-3].
Performance of final products meet the quality indicators for ink material, coupled with no pollution of raw material itself, no waste generated, in line with the future development trend of printing ink.

The Microstructure and Texture of Fine Grain High-Strength IF Steel after Continuous Annealing ZHANG Li-wen1, a ,WANG Zhen-min2,b ,ZHANG Hong-mei ,HOU Jue3,c School of Materials and Engineering ,University of Science and Technology Liao Ning,An shan 114000,China azhanglw1983@163.com Keywords: fine grain high-strength IF steel; texture; holding time; EBSD Abstract: In this paper,the fine grain high-strength IF steel after cold-rolling and continuous annealing was studied.The microstructure under different holding time of fine-grain high strength IF steel was observed by the OM and the TEM technology.
In this paper, the recrystallization texture was examined by selecting different holding time in order to get stronger<111>//ND fiber texture, which is resulting in better deep drawability as well as high strength[1-4]. 2 Experimental Method 2.1 Experimental Material The carbon content of the tested steel is higher than conventional IF steel.
