Abstract: This paper aims to develop a modified animal glue sand binder for foundry casting with improved water resistance and bonding strength. An efficient method is reported by using sodium hydroxide as the catalyst to improve the operability of animal glue binder and allyl glycidyl ether as the modifier to improve the water resistance and bonding strength. Sand specimens prepared using allyl glycidyl ether-modified animal glue binder were cured by... More

Abstract: The paper is dedicated to the consideration of the chemical mesoscopics notions application for the explanation of polymeric materials modification mechanism by the metal carbon mesoscopic composites. The main peculiarities of these nanosized particles are following: a) the presence of unpaired electrons on the carbon cover; b) the structure of carbon cover consists from poly acetylene and carbine fragments; c) the atomic magnetic moment of...

Abstract: Gum Arabic is harvested commercially from wild trees throughout the Sahel from Senegal and Sudan to Somalia and in the northern part of Nigeria. Clumps of gum Arabic were collected and dirt particles were removed, the samples were dried and grounded to fine powder. The Physicochemical properties of gum Arabic was determined using standard methods and the values obtained showed; Moisture content 6.9% ± 5, Soluble content 90.6%, Viscosity 5.45 ±... More
