A novel embed fluorescence method for monitoring the change from emulsion polymeriztion to microemulsion polymerization Haike Feng College of Material, Chemistry and Chemical Engineering, Hangzhou Normal University, Hangzhou 310036, China fhkfhk@163.com Keywords: fluorescence method, emulsion, microemulsion, embed Abstract.
It is of fundamental interest to know when the system will change from emulsion into microemulsion In our novel embed fluorescence method, the fluorescence material is looked like embed in the polymer, and the trace amount of fluorescent probe material is first copolymer with monomer and it has the similar polymerization speed with monomer, so the polymerization degree could be obtained by follow the fluorescence intensity.

New Method and Experimental Study for Fast Evaluating Filling Mould Ability of Al-Si Alloy by Surface Tension Dequan Shi1,a, Dayong Li1,b, Qian Sun 1,c and Guili Gao 1,d 1 Material Science & Engineering College, Harbin University of Science & Technology, Harbin 150040, China a Shidequan77@sohu.com, bdyli@hrbust.edu.cn, csqsq_sq@163.com, dgaoguili79@sohu.com Key words: Filling mould ability, Al-Si Alloy Abstract: On the basis of analyzing the relationship between filling mould ability and surface tension of Al-Si alloy, a new method was put forward that filling mould ability can be fast evaluated by surface tension.
Generally speaking, the molding materials are not been soaked by the molten Al-Si alloys and contact angle is greater than90° [14,15]and liquid surface at thin parts of the mould is convex, therefore, additional pressure produced by surface tension of the molten Al-Si alloy will direct to the liquid interior, which will hinder the molten Al-Si alloys from filling mould, especially the acute angle[16].
Experimental Materials for experiments are eutectic Al-Si alloys and the composition accords with ZL102 of GB1173-86.
