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 ...
Irradiation resistance of elastomeric composites based on NR/CSM blend and waste rubber powder
(RAD Centre, Niš, Serbia, 2021-06-14)
Effect of waste rubber particles (WTR) size on elastomers based on natural rubber and chlorosulfonated polyethylene rubber (NR/CSM= 50:50) was studied. Two types of WTR with different particle size (150–250 μm and 450–600μm) ...
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 ...
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 ...
Strukturiranje elastomernih materijala za primenu u poljoprivredi
(UNIVERZITET U KRAGUJEVCU, AGRONOMSKI FAKULTET U ČAČKU, 2019-03-15)
Poljoprivreda i poljoprivredna industrija zahtevaju elastomeme proizvode koji mogu izdržati dugotrajnu izloženost ekstremnim naponima i hemikalijama. Elastomeri dobijeni od etilen-propilen-dienskog kaučuka (EPDM) nalaze ...
Elastomers based on NR/BR/SBR ternary rubber blend: morphological, mechanical and thermal properties
(Association of Chemical Engeneers of Serbia, 2019-01-24)
The elastomeric materials based on NR/BR/SBR ternary rubber blend were investigated. The polyisoprene (NR), butadiene (BR) and styrene butadiene (SBR) rubbers were used as network precursors and carbon black (CB) as an ...
The influence of different doses of γ-radiation on the hydrolytic stability of modified urea-formaldehyde (UF) resins
Zbog emisije formaldehida (СН2О) iz drvenih proizvoda, gde se urea- formaldehidne (UF) smole, izmedu ostalog, koriste za impregnaciju drvenih panela koje se koriste u unutrasnjosti stambenih i drugih objekata ...
Uticaj razlicitih doza y-zračenja na hidrolitičku stabilnost modifikovanih urea-formaldehidnih (UF) smola
(Srpsko hemijsko drustvo, 2018-05-30)
Zbog emisije formaldehida (CH2O) iz drvenih proizvoda, gde se urea- formaldehidne
(UF) smole, izmedu ostalog, koriste za impregnaciju drvenih panela koje se koriste u
unutrašnjosti stambenih i drugih objekata pozeljno ...
