Due to lead-free pressure, Sn-Ag-Cu solder is regarded as the potential substitute. However, higher melting point and faintish soldering restrict its wide application. Metal or rare earth metal doping can improve soldering. In this thesis, effects of Zn, Ge on electrochemical corrosion behavior Sn-3.0Ag-0.5Cu (SAC) in 3.5wt.% NaCl solution were investigated by potentiodynamic polarization. The migration(ECM)attributed dendrites growth employed salt immersion experiment under direct current...
Organic agents exhibit efficacy in water quality stabilization, yet entail inherent risks of nitrogen and phosphorus diffusion losses. This work introduces a versatile inorganic polyborate slow-release preparations (PSRPs) agents. The effectiveness the PSRPs terms scale inhibition, corrosion resistance, antibacterial activity was empirically validated within simulated cooling station operating at circulation rate 6 L/h 636 L/h. [BO3] units dissociate from complex with Ca0.8Mg0.2, forming...
PCB board is an important part of electronic and electrical equipment. In place piling e-wastes, much heavy metals in boards percolate into soil, air, river etc. which a great threaten to environment. order removal the hazardous materials for WEEE directive, this paper, study on enrichment lead, cadmium ions by multiwalled carbon nanotubes (MWCNTs) as solid-phase extraction adsorbent was employed. ICP-OES used determine adsorbed concentrations. Some valuable guidelines can be drawn from...
Surface boronizing treatment, which forms lattice defects between the boronized layer and metal substrate, is an effective anti-corrosion strategy. We explored bonding mode boron-oxygen ligands Fe substrate. [BO3] bonded to with Fe-B bonds, while [BO4] tends form Fe-O bonds. The larger coordination number of B O beneficial resist Cl- attack. Furthermore, carbon steels were amino-functionalized through a silanol condensation reaction. electronic localization shifted toward Fe, was conducive...
Extracting polybrominated biphenyls (PBB) from electronic and electrical equipment is of high concern due to RoHS directive. PBBs were so toxic for human environment, they are applied largely in as flame retardant. In this thesis, a new method was developed predict the optimal conditions semivolatile organic extraction plastic Enviromental protection. A feed forward type artificial neural network (ANN) model design used investigate effects four independent variables, namely, ratio solvent,...
