[ 1 ] - تاثیر نوع سوخت بر کارآیی فرمولاسیون های پیروتکنیک شامل مواد اشک آور CRو CS

Abstract Aerosolization of tear agents using pyrotechnic formulation containing fuel, oxidant, coolant and binder was investigated. In this study, various tablets including different amounts of potassium chlorate (as oxidizer), lactose or sucrose (as fuel), silica and aluminium oxide (as coolant), nitrocellulose, castor oil and ethyl acetate mixture (as binding system) together with terphtalic ...

[ 2 ] - بررسی رفتار حرارتی یک نمونه پیروتکنیک پایه ی منیزیم حاوی پلیمر پرانرژی وایتون

Magnesium powder are used extensively in formulations of energetic materials. Of powdered can be used as metal fuel in explosives, Pyrotechnics and propellants. The main use of magnesium powder is in Flare Pyrotechnic magnesium,Teflon, Viton (MTV).While the basic problem in using this powder, its high reactivity against oxygen and moisture, this will result in the deactivation magnesium powder ...

[ 3 ] - مطالعه ی رفتار حرارتی پتاسیم نیترات به عنوان اکسیدکننده در حضور سوخت های مختلف

Potassium nitrate as oxidant is one of the main components in the some pyrotechnic compounds. This salt is the cheapest amongst the alkali nitrates and naturally available that widely used in pyrotechnic compounds of infrared, flare and delay compounds. Consequently, the investigation its thermal properties have considerable significance such as thermal stability, lifetime, enthalpy, deflagrati...

[ 4 ] - Study of Optical Properties, Thermal Kinetic Decomposition and Stability of Coated PETN-Litholrubine nano-Composite via Solvent/None-Solvent Method Using Taguchi Experimental Design

In this research, in order to coating PETN particles, nano-pigment of redlitholrubine B 57:1 (NLR) was used in a surfactant environment of cetyltrimethylammonium bromide (CTAB) using solvent/none-solvent (water-acetone) method. Afterstructural studies of PETN-NLR nanocomposite by infrared (FT-IR) and field emissionscanning electron microscopy-Energy dispersive X-ray (FES...

[ 5 ] - مروری بر عوامل موثر بر شدت تابش منورهای مادون قرمز دید در شب

The infrared night vision illuminates are a kind of flare that, with radiation in the near infrared range (700-900 nm) cause illuminates the target in the battlefield and night operations. These illuminates have problems such as low infrared radiation, low burning rate, and so on. Many physical and chemical parameters affect the burn rate and radiation intensity. But the most effective paramete...
