[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 12, N° 6 (11/2015) . - p. 1165-1172 Titre : Preparation and characterization of triazinedithiol nanofilm on surface of sintered NdFeB permanent magnet Type de document : texte imprimé Auteurs : Qin Liu, Auteur ; Tingting Zhao, Auteur ; Zhixin Kang, Auteur Année de publication : 2015 Article en page(s) : p. 1165-1172 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Couches minces Electrochimie Hydrophobie Nanotechnologie Polymérisation Spectroscopie de photoélectrons Triazinedithiol Index. décimale : 667.9 Revêtements et enduits Résumé : In this work, an organic nanofilm was directly prepared on the metal (sintered NdFeB permanent magnet) surface by electrochemical polymerizing of functional triazinedithiol compound 6-(n-allyl-1,1,2,2-tetrahydroperfluorodecyl) amino-1,3,5-triazine-2,4-dithiol monosodium. The polymeric nanofilm was characterized by spectroscopic ellipsometry, static water contact angle meter, and atomic force microscopy. The chemical progress of electrochemical polymerization was studied by cyclic voltammetry. The film formation mechanism was investigated via X-ray photoelectron spectroscopy and Fourier transform infrared reflection spectroscopy and the results showed that the thiol groups play an important role in polymerization of the film on the substrate. This research may provide a basis for fabricating a triazinedithiol film on metal surfaces and have a promising future for expanding the application of depositing polymer films on metals.

Research and application of wireless temperature measurement device in high temperature enclosed environment / Qin Liu in INTERNATIONAL POLYMER PROCESSING, Vol. XXXI, N° 2 (05/2016)  

[article]  inINTERNATIONAL POLYMER PROCESSING > Vol. XXXI, N° 2 (05/2016) . - p. 150-155 Titre : Research and application of wireless temperature measurement device in high temperature enclosed environment Type de document : texte imprimé Auteurs : Qin Liu, Auteur ; C. Chengtao, Auteur ; Y. Huachun, Auteur ; Z. Guocai, Auteur Année de publication : 2016 Article en page(s) : p. 150-155 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Corps creux Essais (technologie) Matières plastiques -- Rotomoulage Mesure -- Instruments Thermométrie Index. décimale : 668.4 Plastiques, vinyles Résumé : Rotational molding, which is widely used in furnishing, entertainment facilities, automotive and boats, military industry and other fields, is a forming method used to produce hollow thermoplastic products. Temperature is the most important process parameter in the rotational molding process, so accurate temperature modulation and control are undoubtedly the main way to ensure product quality. During the rotational molding process, temperature in the oven is very high. Current temperature measuring device cannot make real-time measurement and cannot provide the necessary reference for accurate temperature modulation and control. This article provides an analysis of a wireless temperature measurement device which is used in high temperature enclosed environment, researches the structure, the barrier principle of the temperature measurement device. Finally, tests have been done to verify the working performance. Accurate monitoring and control of the temperature parameter during the rotational molding process can not only improve the working efficiency and energy efficiency of the rotational molding machine, but also provide the reference to design the rotational molding device and molds.
