The burning of building finishing materials containing chemical substances can lead to the spread fire with a large number harmful substances. To prevent this, cellulose, an eco-friendly material that minimizes generation substances, was chosen as main for materials. Wastepaper recycled extract and manufactured by mixing in expandable graphite magnesium hydroxide. flame-retardant performance ev...

The work described in this paper presents a set of experimental tests carried out Controlled Atmosphere Cone Calorimeter (CACC) order to study the evaporation rate 250 ml-‘batch’ n-heptane and methanol poured into an insulated 0.10 × 0.04 m3 steel pan exposed two ‘nominal’ irradiation levels 25 50 kW/m2. A low oxygen concentration is imposed during CACC tests. intent provide data for assessment...

The effectiveness of treatments of the surface layer of novel foam core particleboards were evaluated by means of Cone calorimeter tests. Foam core particleboards with variations of surface layer treatment, adhesives and surface layer thicknesses under similar processing conditions were used to produce the test specimen for the Cone calorimeter tests. Ignitability, heat release rate profile, pe...

The effects of transition metals on the hydrophobicity of nano–structured layered double hydroxides (LDHs) and the compatibility of LDHs/ethylene vinyl acetate (EVA) composites have seldom been reported. NiMgAl–LDHs slightly surface–modified with stearate and doped with transition metal cations (Mn2+, Co2+, Cu2+, Zn2+) are investigated. Compared to the pure EVA, not only were the maximal degrad...

A flame retardant composition was prepared by using phosphoguanidine, guanidine sulfamate, disodium octaborate tetrahydrate and dodecyl dimethyl benzyl ammonium chloride. Veneers were immersed in such mixture to prepare plywood. The combustion characteristics thermal stability of plywood assessed a cone calorimeter TG. Results showed that: (1) High concentration loading beneficial for the fire ...

CMS is a general-purpose detector designed for use in the large hadron collider (LHC) at CERN. The electromagnetic calorimeter will play an important role in electron and photon energy measurements. The benchmark process to evaluate and optimize its performance is H −→ γγ in the intermediate mass range (90 < mH < 150 GeV). For this purpose, each element of the readout chain has to be optimized....

We describe the electric circuits (electrodes) which polarize and readout the Lead-Liquid Argon electromagnetic calorimeter for the ATLAS detector. The paper covers design and material choices of the circuits as well as their production in industry. We also show how the electrodes integrate into the calorimeter and conclude with results from groups of electrodes making up calorimeter modules. ∗...
