The critical coagulation concentration (CCC) is defined as the minimum of counterions to induce colloidal particles. A modified calculation method was proposed calculate CCC. Comparing CCC with traditional method, condition stricter than method. maximum value interaction force that zero, and energy zero. result based on greater energy. can ensure particles coagulate definitely.
Flotation is used to separate valuable minerals from gangue based on the differences in their natural or induced hydrophobicity. recovery a direct indicator of flotation performance. Similarly, induction time and contact angle are often characterize floatability. In order measure correlation these indicators, measurements, measurements tests were performed. The bubble-particle performed with homemade timer. Fourier translation infrared spectroscopy analysis was surface functional groups...
Oil shale is a kind of complex carbonaceous material which an important energy source for electricity production. Reactive molecular dynamics (RMD) simulation useful tool to examine the chemical reactions occurring in processes, providing realistic structural representation and applicable reactive force field (ReaxFF). The (MD) simulations Reaxff were employed investigate mechanisms products distribution process oil combustion. combustion was explored by dividing it into three stages:...
The process and dynamic force of an air bubble detaching from a flat coal surface were investigated calculated, respectively. detachment was captured by high-speed camera, the contact angle area which obtained images indicated that can be divided into two phases: stretching phase sliding phase. main forces acting on confirmed to capillary force, increased pressure external through calculation process. Combined with calculation, it found there maximum at boundary between phase, is defined as...
With the e-commerce developing, some mine enterprises established its own websites in order to provide network services. Now, these have more services for competition of e-business. The extend as annexes are proposed. When additional service added original protocols changed. Because actions may lead security hole should be checked. How hold e-business is front us. We solve this problem by model checker (NuSMV) which can verify property. analyze and show how checker. This method reduce state...
A laser particle size analysis method was proposed to quantitatively evaluate the fine particles coagulation. Laser analyzer used measure distribution of coal slime at different stirring rates and concentrations Ca2+ or Na+. The value d10, d50, d90 can be coagulation performance particles, greater they are, better it is. It found that addition could promote easier for than Na+, best performance, in which 700 µm, occurred conditions 1000 rpm speed concentration above 5 mmol/L. is because...
The high density or large size grains are proposed to be added as ballasting particles achieve a settling rate and low supernatant turbidity for fine particle flocs during the settlement of ore tailings. Settling tests on iron tailings were carried out evaluate effects size, density, dosage initial turbidity. results showed that (2.65 g/cm3) medium (4.67 contributed increase in tailing slurry at all fractions from 0.074 0.5 mm, with peak performance obtained between 0.125–0.2 whereas (6.14...
Network not only brings people convenience, but also becomes a hotbed for breeding crime. And it efficiency, opens new criminal platform the computer network criminals. This paper analyzes performance form and main features of networks crime proposes several control measures based on their features.
MgO-Al 2 O 3 -ZrO composite powders with kinds of mass ratio were synthesized by sol–gel method using MgCl ·6H O, AlCl and ZrOCl ·8H as starting materials, NH ·H a precipitant. The which match zirconium oxide particle size evenly distribute can are advantageous to the formation metastable t-ZrO restrain grain growth additive modified sizing nozzle. Chemical composition, mineral phase, distribution micro-morphology investigated X-ray fluorescence instrument, diffractometer, laser analyzer...
The partially stabilized zirconia ceramic samples were fabricated using MgO stabilizer.The solid solution and migration process of stabilizers in grains under working temperature was studied by XRD, SEM EDS.Results show that after 1710 °C×2 h sintering, stabilizer the sample didn't solid-solute completely, part enriched position impurity SiO 2 to generating forsterite, stability reach highest; With increasing heat preservation time 1540 °C, stabilization completed 8 h.
