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 ...
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 influence of the type of activation of the montmorillonite of hydrolytic stability of the urea-formaldehide nanocomposite
(University of Novi Sad, Faculty of Technology Novi Sad, 2019-10-10)
In this work the hydrolytic stability of nano-composites based on urea-formaldehyde resin (UF) and montmorillonite (K10) as formaldehyde scavenger was investigated. K10 was activated by sulfuric acid (H2SO4) with and without ...
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 ...
A Sensitive Voltammetric Sensor for Caffeic Acid Made from Thermolised Modified UF Resins With Incorporated Fe(III) and Ti(IV) Oxide Particles
(University of Novi Sad, Faculty of Technology Novi Sad, 2022-10-20)
Domestic high performance electrode material was prepared by thermolysis of in situ synthesized urea-formaldehyde (UF) resins modified with Fe(III) nitrate and Ti(IV) oxide in different combinations: iron salt and UF resins ...
The influence of montmorillonite activating method on the hydrolytic stability of urea-formaldehyde resin
(Faculty of Technology, Leskovac, 2019-10-18)
Montmorillonite clays are of great importance for processes such as adsorption and
catalysis and polymer composites fabrication . The textural properties of this filler can
be modified to increase their application. In ...
Domestic material made by calcification of modified UF resins with incorporated Fe-particles-a sensitive platform for electroanalytical quantification of gallic acid.
(University "Union Nikola Tesla", Belgrad, Serbia, 2021-09-24)
In this work, we present domestic high performance electrode material
prepared by thermolysis of in situ synthesized urea-formaldehyde (UF)
resins modified with Fe(III) nitrate. For comparison, material produced ...
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 ...
