“…The effect of the concentration of the combustible gas produced by the solution makes the combustion proceed slowly and achieves the flame retardant effect. The gas phase flame retardancy of composite flame retardants is the result of the combined action of "cooling effect" and "dilution effect" [53]. Hence, the synergistic action between TM LDHs and DTPMP can effectively inhibit smoke and heat release and improve the fire safety of EP.…”

Phosphate tailings (PTs) are solid waste, which is produced by phosphate flotation. In this work, PTs were used as raw materials for the preparation of diethylenetriamine pentamethronic acid (DTPMP) intercalated trimetal (Ca-Mg-Al) layered double hydroxides (TM-DTPMP LDHs) by co-precipitation method. TM-DTPMP LDHs were characterized by X-ray diffraction, fourier-transform infrared spectroscopy, scanning electron microscopy, differential thermal gravimetric analysis, X-ray photoelectron spectroscopy and applied as a flame retardant to improve the fire safety of epoxy resin (EP). The results showed that the composite materials exhibited obvious layered structure. After intercalation, layer spacing increased from 0.783 to 1.78 Å. When the amount of TM-DTPMP LDH in EP was 8%, the limitted oxygen index of the composite material increased from the original 19.2% to 30.2%. In addition, Cone calorimeter (CC) and Raman spectrum results indicated that with the addition of TM-DTPMP LDHs, the value of heat release rate peak (pHRR) and total heat release (THR) were reduced by more than 43% and 60%, while the value of smoke formation rate (pSPR) and the total smoke production (TSP) decreased nearly 64% and 83%, respectively. The significant reduction in the release of combustion heat and harmful smoke during EP combustion may be attributed to the synergistic flame-retardant effect between hydrotalcite and DTPMP. This work exhibited great potential for the green recycling of PTs and the enhancement of the fire safety of EP.

“…A cone calorimeter (Fire Testing Technology, East Grinstead, UK) and FT-IR (Midac Co., MA, USA) were used for the analysis of calorific value and combustion gas. The cone calorimeter is widely used to measure the calorific value of samples (Seo et al 2016;Liang et al 2017), and FT-IR is mainly used to look at the chemical bonding of solids (Cal et al 2016;Li et al 2017), but in this study, it was used for a combustion gas analysis. Calorific value measurement was conducted in accordance with ISO 5660-1 (2015), and the combustion gas analysis was conducted in accordance with the test method specified in ISO 19702 (2015).…”

As biomass has become increasingly important, wood pellets are becoming more widely used, and the storage of wood flour, which is the raw material of wood pellets, has become inevitable. The purpose of this study was to reduce the economic losses from fires during storage of porous combustible materials. To achieve this purpose, the authors analyzed and compared the wood flour loss rate between the use of water and the use of wetting agents to extinguish a deep-seated fire through a scale model experiment. To do this, the authors measured the penetration amount of the water and dilute solutions of wetting agent, the weight change of the wood flour holder, and the emissions on a real time basis when that spray amount was the same. Furthermore, the authors analyzed the calorific value and combustion gas to examine the reusability of the wood flour with the added wetting agent. This study quantitatively demonstrated that the active use of wetting agents in wood flour storage fires dramatically reduced the fire loss rate of raw materials and resulted in early fire extinguishing, which minimizes companies' economic loss.

“…Guo et al applied MgAl-LDH to wood in a two-step process and found that the total smoke production and maximum smoke production ratio were reduced by 58% and 41%, respectively, compared to those of samples without MgAl-LDH [12]. Liang et al introduced 5.0 wt% MgAl-LDH and 5.0 wt% melamine pyrophosphate to medium density fiberboards and found that the peak heat release rate (PHRR) and mean heat release rate (MHRR) were reduced by 27.9% and 7.5%, respectively, compared to those of samples with 3.3 wt% MgAl-LDH and 6.7 wt% melamine pyrophosphate [13].

In recent years, bamboo has been widely used for building materials and household goods. However, bamboo is flammable, so a flame-retardant treatment for bamboo is urgently needed. In this work, nano MgAl-layered double hydroxide (MgAl-LDH) coated on bamboo, which was called MgAl-LB, was synthesized by an in situ one-step method. To determine the optimal in situ time, the effects of different reaction times on LDH growth on the bamboo surface and the flame retardancy of the MgAl-LBs were investigated. The SEM observations show that LDH growth on the surface of bamboo was basically saturated when the in situ reaction time was 24 h. Abrasion experiments show that MgAl-LDH coating has good abrasion resistance. The fire performance of the MgAl-LBs was evaluated by cone calorimeter tests, which indicated that the THR and TSP of the MgAl-LBs were significantly lower than those of untreated bamboo. Taking into account the energy consumption problem, determining the reaction time of 24 h is the optimal reaction time. Compared with untreated bamboo, the THR and TSP of MgAl-LB prepared at 24 h decreased by 33.3% and 88.9%, respectively.
