In this article, the green tribological behavior of Polyamide 12 (PA12) parts, manufactured by MJF with different build orientations was evaluated by ball-on-disc tribological tests under...

2020年11月23日 · The WAXD profiles, variation of crystallinity and d -spacing of PA12 are demonstrated in Fig. 6. The PA12 is in an amorphous state at 235 °C, and three diffraction peaks can be observed below 175 °C, corresponding to (020), (040), and …

The results reveal that an α-form and a mixed (α + γ)-form of PA12 can be obtained by casting at 30°C and (40–80°C), respectively. Meanwhile, the γ-form of PA... In this paper, the influence of...

WAXD又称为大角X射线衍射，如果试样具有周期性结构 (晶区)，则x射线被相干散射，入射光与散射光之间没有波长的改变， 这种过程称为x射线衍射效应，在大角度上测定：又称为大角X射线衍射（WAXD）

The polyamide 12 (PA12) with different crystal forms is prepared with three crystallization paths. The crystal structures and corresponding thermal properties are systematically investigated. The results reveal that an α-form and a mixed (α + γ)-form of PA12 can be obtained by casting at 30°C and (40–80°C), respectively.

This review manuscript presents the applications of PA-based materials in the manufacture of vehicle parts, with a description of their processing, a discussion about their thermal properties and...

PA12尼龙12弹性体有优良的噪音和振动阻尼性，在干燥运转条件下，对钢、POM、PBT和其他材料的 滑动摩擦系数 低、优良的 耐磨损性 和高 体积稳定性。

solution casting, slow melt cooling, and melt quenching were investigated by WAXD, DSC, FTIR, and tensile test. It is found that the form crystal of PA12 can be

2008年12月9日 · The effect of polyhedral oligomeric silsesquioxane (POSS) on crystalline structure and crystalline transition of PA 12 was investigated by wide-angle X-ray diffraction (WAXD) and real time fourier transform infrared spectroscopy (FTIR).

2005年4月4日 · Para-linked aromatic poly (amic n -dodecyl ester) (PA-12), in which long n -alkyl side chains are attached on rodlike aromatic polyamide, was prepared by polycondensation of 2,5-bis (1-dodecyloxycarbonyl)terephthaloyl chloride and 1,4-diaminobenzene.
