Analysis of the blowing agent formulation component analysis

The so-called foaming agent is to make the subject matter into the hole of the material, which can be divided into chemical blowing agents and physical blowing agents and surfactants three categories. Chemical blowing agents are compounds decompose upon heating to release gases such as carbon dioxide and nitrogen, and the formation of pores in the polymer composition; the physical blowing agent is foam pores through the physical form of a substance changes , through expansion of the compressed gas, volatile liquid or dissolved solids formed; blowing agents have high surface activity, can effectively reduce the surface tension of the liquid, and the liquid film surface of the double shells are arranged to surround the air , the formation of bubbles, and then by a single bubble foam composition. Presence in our lives have rubber foam blowing agents, glass blowing agents, foam cement lead, concrete foaming agent, foaming agent plastic, polyurethane foam and the like. Blowing agents generally use infrared spectroscopy analysis (FTIR), means of nuclear magnetic resonance (1H NMR), mass spectrometry (MS), X diffraction analysis (XRD), ICP-MS, X fluorescence spectroscopy, ion chromatography analysis. These tests can be a good means to resolve industrial lubricants formulation, the role of the components of industrial lubricants have a detailed understanding of the various companies develop more convenient, the market dynamics.哲博 detection rely on Zhejiang University academic strengths and analysis personnel, with a variety of analytical testing methods, has accumulated rich experience in chemical analysis products, through professional, reliable and comprehensive means of separation and detection identify unknown qualitative and quantitative analysis, research and production adjustment formula, new product development, improve the production process to provide a scientific basis, but according to customer needs, provide post-tracking technical guidance.
