in the effluent of many industries, which contain fibrous materials, stock, chemicals, surfactant, leather, plastic, dye manufacturing and finishing agent [1-3]. As we all know, many dyes are potentially hazardous......
(28) 式中:Rp0为沿矿体走向长度塑性区的等效半径；G为隔离矿柱上部塑性区岩体的重力；l0为剖面上沿矿体走向长度；l2为隔离矿柱宽度；N为承压的矿壁个数. 图3 塑性区分布图 Fig. 3 Plastic zone distribution 3.1.3 侧向压力系数λ的确定 充填体对矿壁的侧向压力,采用朗金土压力理论进行计算,其主动侧向压力系数为......
compressive stress impeded the growth of the pre-existing porosity in the coatings, protecting the integrity of the coating. The duplex Ni-P/Ni-Mo-P coatings had better corrosion resistance than.... The indentation response of a coating on substrate is determined by the elastic and plastic properties of both coating and substrate. The basic assumption of Oliver–Pharr method was that the contact......
sulfate (AS). 2.5 Neutralization of bauxite residues Experimental bioreactors were prepared in sterile 100 mL glass vials sealed with a gas-tight plastic cap containing an aperture in which a PTFE......
be removed by washing and neutralization. Insoluble alkali is generated in pre-desiliconization, high-pressure dissolution and sedimentation separation with the characteristics of low solubility... g of bauxite residue sample was placed in a polypropylene plastic bowl, to which were added 0,0.50 wt%, 1.00 wt%, 1.50 wt%, 2.00 wt%,2.50 wt%, 3.00 wt%, 3.50 wt% and 4.00 wt% phosphogypsum......
, then the final samples were taken out using quartering method and stored in plastic bags. Each residue sample weighted approximately 2.0 kg. 2.2 Data source and processing All of the samples were taken back......
by the periodical extrusion action of the tool pin. SUTTON et al [21] also found the similar microstructure features due to the metal plastic flow driven by the shoulder of the tool in the surface layer... and corrosion resistance [J]. Corrosion Science, 2016, 106(5): 217-228. [28] WANG D, NI D R, MA Z Y. Effect of pre-strain and two-step aging on microstructure and stress corrosion cracking of 7050......
moulds and compacted on a mechanical vibrating table. Finally, the samples were covered with a thin plastic sheet and stored in a laboratory environment at (23±3) °C for 24 h. After......
surface has attained much interest of the research community due to huge applications in mechanical as well as chemical industries. Other applications of such flows occur in thin plastic sheets......
(1000 mL) sealed by a plastic lid and heated by a water bath (±1 °C). Sodium aluminate solution containing lithium ion (ρ(Na2O)=160.00 g/L, ρ(Al2O3)=181.54 g/L, ρ(Li+)<0.5 g/L) and seed ATH were......
