Preparation and characterization of carbon materials from phenol formaldehyde resin with pore forming substance
This paper describes the carbonization behavior of phenol-formaldehyde resin (PF) blended in the presence of simple organic substances of m-phthalic acid (PA), trimesic acid (TMA) and phloroglucinol (PG). The weight loss and heat flow were monitored in order to study their carbonization behavior by thermogravimetric analysis (TG) and differential scanning calorimetry (DSC), respectively. These ...
متن کاملPreparation and Characterization of Novolak Phenol Formaldehyde Resin from Liquefied Brown-Rotted Wood
The brown-rotted wood was liquefied in phenol with phosphoric acid as catalyst and the resulting liquefied products were condensed with formaldehyde to yield novolak liquefied wood-based phenol formaldehyde resin (LWPF). The results showed that brown-rotted wood could be more easily liquefied than sound wood in phenol. The residue content of liquefied wood decreased continually with the progres...
متن کاملPreparation and Characterization of a Phenol-formaldehyde Resin Adhesive Obtained From Bio-ethanol Production Residue
Phenol formaldehyde (PF) resins are widely used as wood adhesives in the industrial production of exterior-grade plywood panels, oriented strand board panels and particleboards due to their superior performance including high bonding strength, heat resistance, excellent water resistance and chemical stability1. However, phenol, one raw material for the synthesis of PF resins, is a petroleum-bas...
متن کاملThermal Degradation and Stability of Accelerated-curing Phenol-formaldehyde Resin
In order to study the thermal stability of accelerated-curing PF resin, the curing behavior of fresh PF resin was investigated in the presence of single accelerator of methylolurea derivatives (MMU), magnesium hydrate (Mg(OH)2), 25% aqueous solution of sodium carbonate (Na2CO3), and propylene carbonate (PC). Also their optimum combination was added in fresh PF resin. The thermal stability of cu...
متن کاملActivated Carbon Monolith Derived from Polymer and Fast Pyrolytic Char: Effect of Bio-Oil Phenol- Formaldehyde Resin
Activated carbon monoliths (ACMs) were fabricated by H2O activation using powdered fast pyrolytic char (PFPC) as a raw material and bio-oil phenol-formaldehyde (BPF) resin as a binder. The effects of the ratio of BPF resin to PFPC on textural and chemical-surface properties of the ACMs were investigated using elemental analysis, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (...
