hydrofluoric acid etched stainless Steel Wire for solid phase microextraction
Analytical Chemistry, 2009Co-Authors: Dongqing Jiang, Xiuping YanAbstract:Stainless Steel Wire has been widely used as the substrate of solid-phase microextraction (SPME) fibers to overcome the shortcomings of conventional silica fibers such as fragility, by many researchers. However, in previous reports various sorbent coatings are always required in conjunction with the stainless Steel Wire for SPME. In this work, we report the bare stainless Steel Wire for SPME without the need for any additional coatings taking advantage of its high mechanical and thermal stability. To evaluate the performance of stainless Steel Wire for SPME, polycyclic aromatic hydrocarbons (PAHs), benzene, toluene, ethylbenzene, chlorobenzene, n-propylbenzene, aniline, phenol, n-hexane, n-octane, n-decane, n-undecane, n-dodecane, chloroform, trichloroethylene, n-octanol, and butanol were tested as analytes. Although the stainless Steel Wire had almost no extraction capability toward the tested analytes before etching, it did exhibit high affinity to the tested PAHs after etching with hydrofluoric acid.

fabrication of sintered Steel Wire mesh and its compressive properties
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2008Co-Authors: Guo He, Luhai WuAbstract:Abstract Porous Steel Wire mesh with open porosities of 33.90–56.27% and pore sizes of 25–1300 μm has been prepared by metallurgical route. The porous morphologies and porosities of the Wire mesh have been investigated in terms of forming pressure, sintering temperature and sintering holding time. The pore size distribution in the as-prepared samples has been determined by means of metallographic statistic measurement. The results indicate that the total and open porosities are closely related to the forming pressure. Higher sintering temperature and longer holding time in the range of our experiments lead to finer porous structure, coarser joints between Wires, and lower porosities. The Steel Wire mesh exhibits three-stage elastic–plastic behaviors under compressive loading which are similar to that of other cellular materials. The yield strength and Young's modulus of the Steel Wire mesh decrease rapidly with the increase in porosities. When the porosity increases from 33.90 to 56.27%, the yield strength drops from 46.9 to 14.8 MPa and the Young's modulus drops from 1.42 to 0.42 GPa.

high adhesion rubber belt Steel Wire rope
2014Co-Authors: Zhang Chunlei, Liu Hongfang, Xu KaiAbstract:The invention relates to a high-adhesion rubber belt Steel Wire rope which comprises a rope core and a rope strand twisted on the rope core. The high-adhesion rubber belt Steel Wire rope is characterized in that spiral grooves are formed in the surfaces of a plurality of spaced Steel Wires of outer Steel Wires of the rope strand, the depth of each spiral groove is 0.4-0.6% or 1.5-2.5% of the diameter of each Steel Wire, and the spiral spacing of each spiral groove is 0.5-0.6 time that of the diameter of each Steel Wire. Rubber can sufficiently permeate into stranded Wires of the Steel Wire rope, the adhesive strength of the rubber and the Steel Wire rope is improved, the rust resistance of the Steel Wire rope is improved, and the dynamic fatigue life of a conveying rubber belt is prolonged.
