“…For example, Sasobit ® was selected as 1, 2, and 3 %, Advera ® was selected as 4, 6, and 8 %, and Rediset ® was chosen as 1, 2, and 3 % by weight of binder. As per manufacturer's recommendation, 2, 6 and 2 % are the optimum dosage of Sasobit ® , Advera ® and Rediset ® , respectively [9,32]. Thus, selection of one lower and one higher dosage from optimum amount are critical to understand the change in optimum dosage for modified binder, if any.…”

“…It is a long chain hydrocarbon having melting point in the range of 85-116°C. Sasobit ® forms homogeneous solution with base binder and facilitates reduction in viscosity and mixing and compaction temperature about 10-30°C [9,30]. Crystallization of Sasobit ® forms lattice structure in the base binder which improves stability [9,30].…”

“…The G*/sinδ showed satisfactory results for unmodified binders [6][7][8]. However, this parameter showed unconvincing trend for polymer modified binders due to its inability to capture delayed elastic recovery [6,[9][10][11][12][13][14]. Thus, applicability of G*/sinδ parameter for modified binders needs to be investigated thoroughly.…”

The extensive use of conventional petroleum‐based polymers consumes large amounts of energy and emits a lot of carbon dioxide. Therefore, the development and popularization of bio‐based polymer materials are highly significant for ecological reasons. Herein, a series of poly(trimethylene terephthalate)/polyamide 56 (PTT/PA56) blends with different weight ratios were prepared by melt blending of two bio‐based polymers, PTT and PA56. The phase structure, miscibility, crystallization and melting behaviors, crystal structure, and mechanical and water absorption properties of PTT/PA56 blend systems were investigated. The results showed that PTT and PA56 were immiscible in the whole range of compositions. The immiscibility of the blend system intensified with the increase of dispersed phase content. As PA56 content increased, tensile strength and elongation at break of samples assumed an increasing trend, whereas impact strength initially remained almost unchanged and then gradually decreased. In contrast, increasing PA56 content gradually increased water absorption of samples. Comprehensive analysis indicated that the best combination of different properties was obtained for the PTT/PA56 blends including 60–80 wt% PA56.

SUMMARYFoamed gel as a new type of fire extinguishing material is used to prevent the spontaneous combustion of coal. In order to make a comprehensive study on rheological characteristics of foamed gel for mine fire control, by using type NDJ-5s digital viscometer, the factors such as mass concentration of the mixture mixed by thickener and crosslinker, foaming multiple, added salts (NaCl, CaCl 2 , AlCl 3 ), pH value and temperature having influences on the rheological properties of foamed gel have been investigated in this paper. It can be found that foamed gel shows the characteristic of non-Newtonian fluids and has shearthinning properties. With increasing of mass concentration of the mixture, the thixotropy response becomes more significant. When the foaming multiple reaches 20, the apparent viscosity gets the maximum value. The obvious viscosity characteristic of 'polyelectrolyte solution' is observed in aqueous salt solutions when added salts are put into the solution. Under different conditions of pH values, foamed gel has higher sensitivity to acid than alkaline. Zero shear viscosity, depending on temperature, decreases with the temperature increasing. Meanwhile, the fire performances of foamed gel are studied experimentally and theoretically.
