Abstract

Aiming at the building in city, the dangerous sources in construction are analyzed. Some hazardous factors, which are fountains of the accidents, are certainly made. By accidental types analyzed, accident positions analyzed and accident-engineering sorts analyzed; the complexity and authenticity of accident sources in construction can be distinctly set forth. Some safety control measures are made, which can be used to reduce accidents and advance whole safety supervising level in construction.

32. Ammonium Polyphosphate with Crystal Form V by DAP+P2O5

Author

Zhao, Gui Xin and Liu, Gou Sheng

Abstract

Ammonium polyphosphate (APP) is a widely used intumescent flame retardant ingredient, it has six crystalline forms, APP-V is seldom studied in literature. In this study, APP-V was prepared by process of diammonium phosphate (DAP)+P2O5 as raw material, and melamine as condensation agent under dry ammonia. Its properties such as water solubility was tested and compared with APP-II. Further characteristics techniques such as FTIR, XRD, and TGA were used to characterize this product.

33. Simple Synthesis of Micrometer Fe3O4 Particles with Controlled Magnetic Behaviors

Author

Zhao, Gui Zhe, Zhou, Xing, Liu, Ya Qing, and Sun, You Yi

Abstract

Fe3O4 particles were prepared by the co-precipitating method in the presence of polyethylene glycol (PEG). They were characterized by the Transmittance electron microscopy (TEM) and Fourier transform infrared (FT-IR) spectroscope, which indicate the formation of spherical Fe3O4 particles with a wide range of sizes (up to 200 nm in radius) and the polydispersity of particle size below 20%. Furthermore, the magnetic properties of Fe3O4 particles were measured using a vibrating sample magnetometer (VSM), indicating that the particles possess high saturation magnetization at room temperature. These results are attributed that the Fe3O4 particles were directly coated with PEG in a seeded growth Sto¨ber process.
