The main objective of this work was to study a new inorganic adhesive used for wood-based panel. Inorganic adhesive and its poplar plywood were prepared to investigate their properties. Thermo-gravimetric analysis tests revealed that the total mass loss of inorganic adhesive was 76.24%, which was higher than that of phenol-formaldehyde resin (64.97%). The results showed better thermal stability of inorganic adhesive. For inorganic adhesive plywood, approximately 30% decrease in peak of heat release rate, 62% in total smoke production and 20% in mean CO2 yield, respectively, were seen compared to the control by cone calorimeter analysis. Scanning electron microscopy imaged wider glue line of inorganic adhesives plywood, which was related to the bonding strength of plywood. Thus the inorganic adhesive of fireproofing made in lab could be better used for plywood processing.

Waterbased phenol-formaldehyde (PF) resin was prepared and applied to enhance the mechanical strength of aramid paper in this paper. The water dilution stability of prepared PF resin was studied. The chemical structure and the thermal stability of prepared PF resin were characterized. The comprehensive performances of aramid paper before and after strengthen by PF resin were tested. The Micro-morphology of aramid paper was observed by Scanning electron microscopy (SEM0. The results shows that the comprehensive performances of aramid paper were greatly enhanced after being strengthen by PF resin. Its expected that the prepared PF resin has promising application in aramid paper industry.

Starting Point

The objective of this research was to investigate thermal stability and dynamic mechanical behavior of nano-SiO2/phenol formaldehyde resin (PF) nanocomposites with various nano-SiO2 at 2 wt% loading content. The nano-SiO2/PF nanocomposites were fabricated by two-roll compounding and compression molding technology. The storage modulus (E′) at the starting point of 50 was increased by adding various nano-SiO2 into PF matrix. The E′ of the nanocomposite with only 2 wt% of SiO2 synthesized under ultrasonic irradiation (U-SiO2) was 2 times higher than that of the control PF. Thermal expansion and the coefficient of thermal expansion of nano-SiO2 loaded nanocomposites were lower than that of the control PF in the range of 100–200 and 200–250 . Thermogravimetric analysis demonstrated that the thermal stability of nanocomposites was evidently enhanced. In comparison, U-SiO2 reinforced nanocomposites showed higher thermal properties than those reinforced by mesoporous silica (SBA-15) and SiO2 synthesized by stirring (S-SiO2).

The paper evaluates the effectiveness of the use of graphene nanostructures in the purification of lead (II) ions to improve the ecological situation of water bodies. The mechanisms and characteristic parameters of the adsorption process were analyzed using empirical models of isotherms at temperatures of 298, 303, 313 and 323 K, which correspond to the following order (based on the correlation coefficient): Langmuir (0.99) > Temkin (0.97) > Dubinin – Radushkevich (0.90). The maximum adsorption capacity of the material corresponds to the range from 230 to 260 mg/g. We research the equilibrium at the level of thermodynamic parameter estimates, which indicates the spontaneity of the process, the endothermic nature and structure change of graphene modified with phenol-formaldehyde resin during the adsorption of lead (II) ions, leading to an increase in the disorder of the system.
