集裝箱檢測大廳輻射場劑量分佈及其散射體的影響The dispersion of the modified nano - sized caco3 in the pvc matrix was observed in tem ( transmission electron microscope ). the influences of surface treatment and the contents of nano - sized caco3, extrusion technology and other additives on the properties of the composites were investigated. the results show that the surface treatment of the nano - sized caco3 particles with wet method enlarged the specific surface area and reduced the surface energy of the particles, and made the particles dispersed at the nanometer level in the pvc matrix, which improved the mechanical properties of the composite
本課題為了解決納米caco _ 3在pvc中的分散問題,對納米caco _ 3粒子進行了濕法處理,採用雙螺桿擠出法制備出具有良好性能的pvc -納米caco _ 3復合材料;對復合材料的力學性能和加工性能進行了測試;利用tem ( transmissionelectronmicroscope ,透射電子顯微鏡)觀察了納米caco _ 3粒子在pvc基體中的分散情況;討論了納米caco _ 3的表面處理方法、納米caco _ 3的含量、復合材料的制備工藝以及各種助劑對復合材料各項性能的影響。The content of styrene was found to be dependent on the investigated grafting conditions, of which the dose rate and monomer concentration were the major conditions, and the dependence of the initial rate of grafting on the dose rate and the monomer concentration was found to be of 0. 4286 and 1. 1662 orders, respectively. the results indicate that the grafting reaction is competitive and the copolymerization and the graft - copolymerization are existing at the same time. the grafting proceeds by the so - called front mechanism in which the grafting starts at the surface of the films and moves toward the middle of the film by successive diffusion of the styrene through the grafted layers
我們對輻射接枝反應中的各個因素如:單體濃度、輻射劑量率、輻射劑量以及反應時間進行了研究分析,結果表明:單體濃度和劑量率是反應的兩個主要影響因素,它們對反應速率的影響指數分別為1 . 1662和0 . 4269 ;反應的動力學方程為: rg k [ d ] ~ ( 0 . 4269 ) [ m ] ~ ( 1 . 1662 ) ;認為接枝反應是一競爭反應,單體的均聚反應和在聚合物上的接枝反應同時存在,單體濃度的高低決定著競爭反應的方向;輻射接枝反應是從聚合物表面開始的,隨著溶劑的溶脹和單體的擴散最後在整個膜體中形成接枝產物。Testing of pigments and extenders ; determination of relative scattering power of white pigments ; black - ground method, procedure, example, test medium plasticized polyvinyl chloride plasticized pvc
