查询词典 high temperature

In this paper, a turbostratic CN precursor was prepared by means of pyrolysis of melamine, then it was treated by high temperature and high pressure. The pyrolysis process of melamine, mechanism of hydrogen elimination and the effect of catalysts on pyrolysis of melamine were studied. The crystal structures, bonding states and chemical compositions of CN precursor obtained by pyrolyzing melamine are analyzed by X ray diffraction, burning spectrum, scanning elecron microscope and Fourier transform infrared Spectroscopy.

In this thesis, we concentrate on the development in theoretical prediction and experimental synthesis of CN compounds in the recent 10 years. By means of ion beam sputtering, treating melamine at high temperature and pressure, pyrolyzing melamine and treating pyrolysis products of melamine by impulsive discharge and high-speed impact, we explore the routes to synthesize carbon nitrides. The chemical compositions, crystal structures and bonding states of the CN films and powders obtained from the experiment are studied by the use of EDX, XRD, TEM, XPS and FTIR.

Adopting equal density method to prepare PMA, it is not need to add reactive additives and the problem of pollution and selectivity to reactive additives avoided. Adopting the method, the asphalts modified by polymers, including SBS, LDPE, SEBS were easily prepared with storage stability at high temperature and cost less. With the method of equal density, high performance and good storage-stability of SBS modified-asphalts were prepared by premixing SBS and kaolinite or diatomite clay.

采用等密度方法将聚合物与填料预先共混制备的改性沥青不加入反应添加剂，回避了反应共混改性难以控制和环境污染问题，采用此方法可以制备出高温贮存稳定的不饱和聚合物SBS、饱和聚合物SEBS及LDPE改性沥青，且成本低廉，在实际应用中所添加量情况下填料的介入对改性沥青其它性能影响不大。
