Evaluation of chestnut shell and coffee waste with phenol-formaldehyde resin for plywood filler
نویسندگان
چکیده
Chestnut fruit shell and ground coffee waste were evaluated as filler raw materials for plywood adhesive. A phenol-formaldehyde (PF) resin was formulated in the laboratory manufacture. Specification characteristics determined on PF resin, including nonvolatile solids, gel time, viscosity, etc. The synthesized mixed with extender, NaOH. Plywoods uniformly made mixture tested tension shear strength after aging method, modulus of rupture (MOR) thickness swell according to procedures Korean Standard KS F 3101 3114. All each type showed good physical mechanical properties. performance test results indicated that chestnut would be suitable

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...

A powdery product was obtained by the reaction of methylolated melamine with alkyl resorcinols to form melamine-bridged alkyl resorcinols (MARs). The effects of the addition of this powder on the bonding strength and formaldehyde emission of urea–formaldehyde (UF) resins were investigated. Three types of UF resins with a formaldehyde/urea molar ratio of 1.3 synthesized by condensation at pH 1.0...
