Published: September 2013

During firefighting, within firefighter clothing, underwear and station wear gets heavily wet due to firefighting water and moisture from the body. Water has higher thermal conductivity relative to air and it has been expected that heavily wet condition within the firefighter clothing makes faster skin burns. The objective of this study is how the wet condition within a firefighter clothing makes faster heat transfer from feeling pain and to being 2nd degree of skin burns relative to the dry condition in case of routine firefighting operation in a building (up to 20 kW/m2). Aramid station wear and cotton underwear, generally used by a Japanese firefighter, have been selected and cut 0.15 m x 0.15 m to attach an ISO 9151 copper sensor. A cone shape electric heater, which produces 12 kW/m2 to 20 kW/m2, was used to heat the fabrics. Scenario of fabrics are that (1) wet station wear and dry underwear, (2) wet station and wet underwear, (3) dry station wear and wet underwear, and (4) dry station wear and dry underwear. Evaluation method was by a heat transfer index (HTI) by ISO 9151. The time to rise temperature of 12 and 24 °C (HTI12 and HTI24), and heat transfer rate (dT/dt) were investigated for above four scenarios. The result shows that there was significant impact by condition of station wear, but little impact by underwear. In heat transfer rate (dT/dt) analysis, for the situation of feeling pain to the 2nd degree of skin burns (from HTI12 to HTI24), heat transfer rate was about 50% higher relative to the dry station wear condition. This result indicates that it is possible to be 2nd degree of skin burns easily as soon as a firefighter feels the pain, if he/she wears wet station wear.

Authors: Wei Jun Fang , Zhu Fang
Published: September 2013

A nanocrystalline HZSM-5 zeolite was directly synthesized by two-stage varying-temperature synthesis method. The effects of second stage time and temperature on the particle size and morphology were of interest. The morphology of particles were specified by scanning electronic microscopy (SEM) and crystallinity of the samples were recorded by X-ray diffraction (XRD) test results. It was observed that second stage time had a strong effect on crystallinity and morphology; a highly crystalline ZSM-5 zeolite with twinned crystals was synthesised at 180 °C, 60h (second stage time and temperature ). The HZSM-5 particles synthesised at 180 °C, 18h (second stage time and temperature ) were 300600 nm in size and constructed by primary HZSM-5 nanocrystals of 20~30 nm.

Authors: Wei Jun Fang , Zhu Fang , Zhang Xiao Yan
Published: September 2013

Porous α-alumina supports were seeded with monodisperse nanocrystalline HZSM-5 zeolite and calcined. The supports were treated in a synthesis solution to grow the seeds into HZSM-5 membrane with aluminum nitrate (Al (NO3)3), tetraethyl orthosilicate (TEOS), and tetrapropyl ammonium hydroxide (TPAOH) as raw materials. X-ray diffraction (XRD) characterization results showed that the membranes consisted of well-crystallizedH ZSM-5. The influence of crystallization time on morphology of HZSM-5 membranes was represented by scanning electronic microscopy (SEM) characterization: the HZSM-5 zeolite membranes on the supports were defect free and the membrane thickness was increased with the crystallization time prolonged.

Published: September 2013

CoFe2O4 (CFO) nanoparticles was synthesized by a simple hydrothermal method using NaOH solution as a mineralizer at 200 °C for 4 h. It was found that CFO particle sizes decreased firstly and then increased with the increasing of NaOH concentration, and had a minumum value about 10-20 nm when selected 4 mol/L NaOH solution, indicating the NaOH concentration played an important role in controlling the particle size of CFO powders. The room temperature magnetic measurements showed that the saturation magnetization value was 48 emu/g, which is less than the bulk value. The synthesis method is possible to be a general approach for the preparation of other spinel ferrite nanoparticles.
Numerical Simulation for the Roll Forming Process of a Channel Steel
Authors: Feng Guang Hong , Zhang Hong Liang , Zhang Pei
Published: September 2013

In this study, finite element method is used to analyze the stress and strain distributions in various regions of a channel steel during the roll forming process, and reveal the deformation pattern of the channel steel. The results indicate that the deformation and thickness reduction of sheet metal mainly concentrates in the corner and the ends of web section, while it is insignificant in the channel edges and the central portion of the web. During the stable stage of roll forming process, the rolling force fluctuation in each pass is related to the change of forming angle in that pass. For the pass with the largest change of forming angle, the most significant fluctuation in rolling force is observed. It is also the pass that most probably causes quality issues to the final product. Finally, it is found that changing the forming angle distribution among all the passes cannot reduce the stress fluctuation among the passes. As such, the process optimization needs to be realized by other approaches.

The results indicate that the glass fibre coated with starch sizing agent is greatly influenced by the environment. It was confirmed that the starch sizing agent is the main factor affecting the stiffness of glass fibre. Using SEM, FTIR, XRD, DSC, three kinds of starch sizing agents under different storage conditions were studied. The results show that dried starch films produce holes that absorb water in humidity environment. Some bound water formed during the moisture absorbing process. The molecular structure, ordered degree and heat resistance of deteriorated starch is affected by the wet storage conditions.
