The effect of UV-irradiation on the thermal stability of modified urea-formaldehyde resins with thermally activated montmorillonite
(RAD Centre, 2021-06-14)
The montmorillonite as a 2:1 smectite type clay has two tetrahedral sheets of silica sandwiching the alumina octahedral sheet. The particles of this mineral are plate-shaped with the thickness of 0.96 nm and an average ...
The influence of modification and the particle size of the montmorillonite on the hydrolytic stability of urea-formaldehyde composite
(Materials Research Society of Serbia, 2019-09-02)
Urea–formaldehyde (UF) resin adhesive is a polymeric condensation product of formaldehyde with urea and is considered as one of the most important wood adhesives. In spite of some advantages such as lower cost, fast curing, ...
Correlation between methods of activation of montmorilonite K10 and formaldehyde content in urea-formaldehyde composites
(Faculty of Management Herceg Novi, 2022-05-26)
In this paper, the methods of activation of montmorillonite (MMT) K10 with the content of formaldehyde (FA) in urea-formaldehyde (UF) composites are compared. MMT K10 samples were activated in two ways: thermally(physical ...
Cross-linked bio/inorganically modified urea-formaldehyde resins: influence of γ-radiation on formaldehyde content
(2022-06-13)
The effect of γ–irradiation on hydrolytic stability of nano-silica, nano-titania, and wood flour (WF) modified urea-formaldehyde (UF) resins was investigated. Modified UF resin with wood flour (Pinus silvestris L.) as ...
INFLUENCE OF MODIFIED MONTMORILLONITES ON FORMALDEHYDE CONTENT IN UREA-FORMALDEHYDE/MONTMORILLONITE COMPOSITES
(University of Novi Sad, Faculty of Technology Novi Sad, 2022-10-20)
The effect of different montmorillonites (KSF and K10) and their modifications (Na-KSF, Na-K10) on content of formaldehyde-FA (free and liberated) modified urea-formaldehyde (UF) composites was investigated. KSF and K10 ...
