An eco‐friendly bio‐filler was prepared by reusing of chicken eggshell (CES), and well characterized Fourier transform infrared (FTIR) spectroscopy, scanning electron microscope (SEM)‐energy dispersive X‐ray spectroscopy (EDS), fluorescence spectrometry (XRF), thermo‐gravimetric (TG) analysis. The influence CES on the thermal stability, flame‐retardant, smoke suppression properties epoxy‐based traditional intumescent system investigated limited oxygen index (LOI), UL 94 test, cone...
Small-section steel-shell concrete immersed tube tunnels are intended for minibuses and have a low fire heat release rate. Standard rise curves do not apply to such tunnels. In this study, coupled method of computational fluid dynamics (CFD) the finite element (FEM) was used simulate structural temperature distribution in Firstly, tunnel model established obtain inhomogeneous field during fires. Subsequently, three-dimensional transfer analysis section characteristics structure with without...
A laboratory fire-extinguishing system was applied to investigate the effect of gas-liquid ratio on performance aqueous film-forming foam (AFFF) in diesel pool fire, and proposed mechanism AFFF is carefully analyzed. The results show that possesses shortest extinguishing time 42s lowest liquid consumption 210 g at a 16, exhibiting best performance. Chemical analysis indicates proper beneficial enhance expansion drainage rate affect cooling covering effects foam, thus achieving optimum...
A three-dimensional ground-penetrating radar (GPR) captures non-destructively internal pavement distress characteristics. However, interpreting images and data analysis pose challenges. To improve the accuracy of identification, a digital model was established. Firstly, initial electromagnetic signal were pre-processed to effectively eliminate spurious signals enhance characteristic signals. The located, GPR typical extracted summarised. Next, 3D dataset constructed based on echo generated...
The synergistic flame retardant effects between aluminum hydroxide (ATH) and halogen-free retardants in high density polyethylene (HDPE) composites used for geo-grid were characterized by carrying out limited oxygen index (LOI) test, UL94 vertical burn alcohol blow 1amp test cone calorimeter. fire residue structure of the was examined means digital camera. results indicate that there are obvious ATH including expandable graphite (EG) Red phosphorus (RP). In comparison with ATH/RP system,...
Abstract In this article, ammonium dihydrogen phosphate (ADP) was successfully intercalated into kaolinite (Kaol) to prepare a novel synergist named ADP‐intercalated (K‐ADP). The chemical structure of K‐ADP thoroughly characterized using various analytical methods, and then combined with polyphosphate (APP) enhance the fire safety epoxy resins (EPs). flammability results indicate that combination APP exerts super positive effects on reducing heat release smoke emission EPs than mixture Kaol...
<title>Abstract</title> Rolling bearings are of fundamental importance in rotating machinery. Outer - ring spalling, particular, stands as a commonly encountered and quintessential defect. The dynamic model rolling enables an in-depth analysis the response characteristics associated with local bearing defects. In this paper, by meticulously examining change spherical center position elements pass through fault region outer ring, random sequences utilized to simulate appearance bottom....
