KORELACIJA IZMEĐU NAČINA AKTIVIRANJA MONTMORILONITA K10 I SADRŽAJA FORMALDEHIDA U UREA-FORMALDEHIDNIM KOMPOZITIMA
(Faculty of Management Herceg Novi, 2022-05-26)
U ovom radu je izvršeno poređenje načina aktiviranja montmorilonita (MMT) K10 sa sadržajem formaldehida (FA) u urea-formaldehidnim (UF) kompozitima. Uzorci MMT-a K10 su aktivirani na dva načina: termički i pomoću sumporne ...
The influence of the modification of the montmorillonite KSF and K10 on the hydrolytic stability of UF composites
(2021-09-24)
In this work, the hydrolytic stability of composites based on the urea-formaldehyde resin (UF) and montmorillonite-MMT (K1 0 and KSF) as a formaldehyde (FA) scavenger was investigated. K10 and KSF were activated by sodium ...
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 ...
The effect of UV irradiation on hydrolytic stability of urea-formaldehyde resins filled with thermally modified montmorillonite
(RAD Centre, Niš, Serbia, 2019-06-10)
The hydrolytic stability of organic-inorganic nano-composites prepared by a two-stage
polymerization of urea-formaldehyde resin (UF) filled with thermally activated montmorillonite (MMT) has been assessed before and after ...
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 ...
Radiation stability and thermal behaviour of modified UF resin using biorenewable raw material-furfuryl alcohol
(Elsevier, 2019-06-15)
The thermal stability of organic-inorganic nano-composites prepared by a two-stage polymerization of urea-formaldehyde resin (UF) with furfuryl alcohol (FA) and TiO2 before and after irradiation has been researched. The ...
Biocomposites Based On Cellulose And Starch Modified Urea-Formaldehyde Resin: Hydrolytic, Thermal And Radiation Stability
(Wiley, 2019-04-10)
Two biocomposites based on cellulose (UFC) and starch modified urea formaldehyde (UFS) resin (F/U ratio of 0.8) were synthesized using the same procedure. The hydrolitical, thermal, and radiation stability of biocomposites ...
Hydrolytic, thermal and radiation stability of modified urea-formaldehyde composites: influence of montmorillonite particle size
(Elsevier, 2022-06-15)
Urea-formaldehyde (UF) composites with a formaldehyde/urea (FA/U) ratio = 0.8 and different particle sizes of montmorillonite (MMT), namely UF/KSF and UF/K10 were synthesized. The hydrolytic stability of modified UF ...
