“…A move for cleaner, environmentally friendly materials has led to the emergency of other materials which do not have the toxic effects associated with halogenated materials [12][13][14] and require low loadings to comply with fire safety standards. Lamella materials which include clays (both anionic and cationic), graphene, and zirconium phosphate have been subject of intense research with anionic clays, and layered double hydroxides (LDH) receiving the lion's share of the efforts [2,[15][16][17][18], and their synergies with other FRs have been reported [15,16,19]. Layered double hydroxides have been shown to act in the condensed phase by promoting charring process during the thermal degradation and combustion of polymers [20,21].…”

The flame retardancy and thermal stability of polystyrene compounded with Bis(2,4-dicumylphenyl) pentaerythritol diphosphate (DPP) and or a palmitate containing magnesium aluminum LDH (MgAl-C16 LDH) were investigated via thermogravimetric analysis, cone calorimetry, and pyrolysis combustion flow calorimetry. Cone calorimetry and thermogravimetry measurements revealed that the addition of 5 and 10 mass% of MgAl-C16 LDH to PS resulted in substantial reduction in peak heat release rate (PHRR) (47 and 61 %, respectively) of the polymer and minimal improvements in thermal stability (5 and 2°C, respectively, for the temperature at which 50 % mass loss occurs, DT 50 ). On the other hand, there was insignificant reduction in PHRR for composites containing DPP at loadings of 5 mass%, while loadings of 10 mass% resulted in a relatively low reduction of 22 %. This difference was attributed to the more compact residue formed by the LDH systems during cone calorimetry analysis. There was substantial improvements in the thermal stability of PS compounded with 10 mass% of DPP with DT 50 being 21°C. The combination of DPP and LDH resulted in a negative effect on the flammability performance of the LDH; thus, we did not observe any synergism between the LDH and DPP. Results from micro-scale combustion calorimetry did not correlate with results from cone calorimetry.

“…In tread rubber blends, the clay minerals lead to tire adhesion improvement to wet road and better adhesion of rubber to steel cords. Clays and clay minerals are commonly used as a partial replacement of the carbon black representing the filler into rubber blends in order to reduce the prices of products as well as to make these products to be eco-friendly [3,4,5].…”

Study of clay minerals effect on curing characteristics of polymer blends and physical-mechanical properties of prepared vulcanizates

et al. 2018

The given paper deals with the study of the properties of clay minerals, namely montmorillonite and moreover, it is focused on effect of these clay minerals on the curing characteristics of the polymer blends and the physical-mechanical properties of prepared vulcanizates. Montmorillonite is a major clay mineral which has a wide application in many industrial branches. It belongs to the group of dioctahedral smectite minerals with structural type in the ratio of 2:1. Characteristics of prepared modified and organomodified clay minerals are based on sulphur vulcanisation accelerators which are used for the preparation of real polymer blend where they represent a partial replacement of the common carbon black filler and then, the effect on the curing characteristics of polymer blends as well as physical-mechanical properties of the prepared vulcanizates are investigated. The results exhibit that the clay-based filler (modified and organomodified clay minerals) can be used as a partial replacement while the quality of the prepared blends is preserved.

“…Often, however, the uncertainties are bounded by their minimum and maximum values and in this case, the task changes to the interval analysis of the problem [5][6][7][8][9]. The basic and the easiest method of solving this type of task is the Monte-Carlo method, where we randomly generate points from the uncertainty interval and perform an analysis of the investigated problem for these random combinations of uncertainty, and finally we determine the combination of unknown parameters at which the investigated function has reached the extreme [10][11][12][13][14][15][16][17][18][19][20].…”

Comparation of nonuniform and uniform Monte - Carlo Searching

et al. 2018

Nonuniform Monte-Carlo method is often used for optimization and solution of function mapping. This method has some disadvantages. New genetic algorithm, based on uniform Monte-Carlo is proposed by authors reduce disadvantage of nonuniform Monte- Carlo method. Both of these methods are based on random number generation and therefore the solutions are approximate. Statistical evaluation of solutions is used for comparison.
