Illumination flares from the past to the present have been used in order to create light and signal in critical conditions. Flare formulation consists of three components i. e., fuel (magnesium) and oxidants (sodium nitrate) and a binder. Performance of illumination flares depend on many parameters such as ratio of oxidizer to fuel, particle size of fuel, binder type and binder weight percent. ...

Despite the fact that Titanium material has been considered as difficult to cut material, its usage has been increasing day by day in all engineering sectors; wherever criticality is encountered. Many studies are going on in view of increasing tool life at high cutting speed to improve productivity. In this study, attempt has been made to see the effect of iron as a partial substitution  along ...

Hydroxyl terminated polybutadiene (HTPB) is the most commonly used binder in composite solid propellants. However, due to its non-energetic character, in practice it is just a dead weight; Therefore, replacing HTPB with an energetic polymer is essential. In this research, nitrated hydroxyl terminated polybutadiene resin (NHTPB) with 12.2% nitration rate, in combination with HTPB resin was used ...

A way to increase the specific impulse of solid propellants is using the energetic components as energetic binder or energetic plasticizer in the propellant formulations. Hydroxy terminated poly butadiene (HTPB) is the one of pre-polymer which was specifically synthesized for its use as a propellant. Incorporating of PEG into HTPB chains lead to increasing the polarity of binder and maybe preve...

Plastic bonded explosive PBXN-103 as an underwater charge based on energetic binder system uses in warhead section of several navy weapons. Metriol trinitrate (MTN), triethylene glycol dinitrate (TEGDN) and pelletized nitrocellulose are basic ingredients of binder system in PBXN-103 formulation.  In this research the effects of applying accessible Poly glycidyl nitrate (PGN) as binder, were inv...

Human umbilical cord serum was found to contain both free folate and folate complexed to a high-molecular weight factor. The complexed folate was bound to a very high affinity binder and was present in concentrations equivalent to as much as 60 ng of 5-methyltetrahydrofolic acid per ml of serum. Acidification of the serum caused disassociation of the folate-binder complex. Released folates were...

PURPOSE Agglomeration in suspension is a size enlargement method that facilitates operation of solid processing and preserves the solubilization properties of fine particles. A small quantity of binder liquid is added into a suspension of microparticles, directly in the stirred vessel where the precipitation or crystallization took place. This study deals with the evaluation of the effect of ag...

This work demonstrates the variability in performance between SnO(2) thick film gas sensors prepared using two types of film deposition methods. SnO(2) powders were deposited on sensor platforms with and without the use of binders. Three commonly utilized binder recipes were investigated, and a new binder-less deposition procedure was developed and characterized. The binder recipes yielded sens...
