studying thermal behavior and formaldehyde emission of modified urea formaldehyde resin by furfural
there are adequate sources for wood adhesives, but scarcity of oil resources can affect the cost and future availability of oil based resins. for avoiding of this process, seeking for feasibility of replacement of these oil feedstocks is necessary. in present work, thermal behavior of urea formaldehyde resin modified by furfural was investigated. the thermo-gravimetry was used for this purpose,...
متن کاملmodification of urea- formaldehyde resin with furfural in particleboard for reduction of formaldehyde emission
partial replacement of formaldehyde with furfural in the urea-formaldehyde resin on the formaldehydeemission, physical and mechanical properties of particleboard was investigated. the modulus ofrupture (mor), modulus of elasticity (moe), internal bond (ib), water absorption (wa), thicknessswelling (ts) and formaldehyde emission (fe) of poplar particleboards made with the modifiedresins were mea...
متن کاملMelamine-Bridged Alkyl Resorcinol Modified Urea– Formaldehyde Resin for Bonding Hardwood Plywood
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...
متن کاملRattan Cane Modified with Polyethylene Glycol Melamine-Urea-Formaldehyde Resin
To effectively improve the strength of Plectocomia pierreana rattan cane without reducing its toughness, the cane was impregnated with a new water-soluble melamine-urea-formaldehyde (MUF) resin modified with low-molecular-weight polyethylene glycol (PEG), marked as PMUF. The PMUF synthetic process was optimized using an orthogonal test L9(3). Results showed that the dimensional stability, densi...
متن کاملMelamine-modified urea formaldehyde resin for bonding particleboards
For the development of a cost-effective melamine-modified urea formaldehyde resin (MUF), the study evaluated the effects of reaction pH and melamine content on resin properties and bond performance of the MUF resin adhesive systems. Eight resins, each with three replicates, were prepared in a factorial experiment that included two formulation variables: two reaction pHs (i.e., 4.5 and 8.0) and ...
