Antibacterial and anti-flaming PA6 composite with metathetically prepared nano AgCl@BaSO

Wei Zhang, Boren Xu, Caihong Gong, Chunwang Yi, Shen Zhang

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 2, Pages 340-350 doi: 10.1007/s11705-020-1942-9

Abstract: Then, the dried co-precipitates were melt-compounded with polyamide 6 (PA6) resins at a specified massagent or carrier, the nanoparticles of AgCl@BaSO co-precipitates were homogeneously dispersed in the PA6the antibacterial performance, along with the flame-retardance and anti-dripping characteristics of PA6In addition, the PA6 composites possessed high spinnability in producing pre-oriented yarn.

A comprehensive analysis of a 3-P (Pa) S spatial parallel manipulator

Yuzhe LIU,Liping WANG,Jun WU,Jinsong WANG

Frontiers of Mechanical Engineering 2015, Volume 10, Issue 1, Pages 7-19 doi: 10.1007/s11465-015-0324-3

Abstract:

In this paper, a novel 3-degree of freedom (3-DOF) spatial parallel kinematic machine (PKM) is analyzed. The manipulator owns three main motions (two rotations and one translation) and three concomitant motions (one rotation and two translations). At first, the structure of this spatial PKM is simplified according to the characteristic of each limb. Secondly, the kinematics model of this spatial PKM is set up. In addition, the relationship between the main motions and concomitant motions is studied. The workspaces respectively based on the outputs and inputs are derived and analyzed. Furthermore, the velocity model is put forward. Two indexes based on the velocity model are employed to investigate the performance of this spatial PKM. At last, the output error model can be obtained and simulated. The comprehensive kinematics analysis in this paper is greatly useful for the future applications of this spatial PKM.

Preparation and rheological behaviors of PA6/SiO2 nanocompiste

WEI Shanshan, LIU Yuejun, LI Xianggang, HUANG Yugang, WANG Xiayu, ZHANG Ping

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 4, Pages 332-337 doi: 10.1007/s11705-007-0060-2

Abstract: The polyamide 6 (PA6)/SiO nanocomposites were prepared by in situ polymerization and the rheologicalThe results showed that the SiO particle size was around 50 nm and the particles dispersed evenly in PA6The non-Newtonian indexes of nanocomposites were smaller than those of pure PA6.The rheological behaviors revealed that there were strong interactions between PA6 macromolecule chains

The Research and Application of Interval Numbers of Three Pa rameters

Hu Qizhou,Zhang Weihua, Yu Li

Strategic Study of CAE 2007, Volume 9, Issue 3, Pages 47-51

Abstract:

To evaluate the cost risk and the schedule risk of the spaceflight project, the schedule-cost (S-C) correlation coefficient is directly appointed according to the experts' experience usually. This paper deduces SDMCU (the schedule distribution model considering the effect of the cost uncertainty), and then proposes the approximate formula to estimate the ln (S)-C correlation coefficient based on the models of SDMCU and CDMSU (the cost distribution model considering the effect of the schedule uncertainty). Furthermore, an approximate relationship expression of the S-C and the ln (S)-C correlation coefficients is put forward according to general facts and the Taylor expansion, and advanced by means of mass numerical validation is the general rule of obtaining the estimation value of the schedule-cost correlation coefficient based on the historical data.

Preparation and properties of hollow fibre nanofiltration membrane with continuous coffee-ring structure

Xiuzhen Wei, Xufeng Xu, Yi Chen, Qian Zhang, Lu Liu, Ruiyuan Yang, Jinyuan Chen, Bosheng Lv

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 2, Pages 351-362 doi: 10.1007/s11705-020-1943-8

Abstract: Polyamide (PA) hollow fibre composite nanofiltration (NF) membranes with a coffee-ring structure andtransform infrared spectroscopy were used to characterize the chemical structure and morphology of the PAThe results showed that GO was successfully entrapped into the PA functional layer.Under neutral operating conditions, the PA/GO membrane showed typical negatively charged NF membraneThe PA/GO NF membrane showed better antifouling performance than the PA membrane.
