[ 1 ] - Influences of NCO/OH and triol/diol Ratios on the Mechanical Properties of Nitro-HTPB Based Polyurethane Elastomers
The present study describes the effect of NCO/OH and triol/diol ratios on the mechanical properties of Nitro functionalized Hydroxyl-terminated polybutadiene (Nitro-HTPB) elastomers. The progress of the cure reaction of Nitro-HTPB and toluene diisocyanate (TDI) is evaluated by following up the variations in the IR absorption bands of the NCO stretching and the CO ...
[ 2 ] - سنتز و بررسی خواص الاستومری کوپلیمر سه دستهای انرژیزای GAP-PB-GAP
The binder is an essential ingredient of solid composite propellants. Today, the industrial military scientists have been focused on finding and developing the new energetic binders to enhance the performance of the composite propellants. In this research, triblock hydroxyl-terminated polybutadiene (HTPB) with Glycidyl azide polymer (GAP) was synthesized as a new energetic binder. In the first ...
[ 3 ] - سنتز کوپلیمر تری بلاک پلی کاپرولاکتون-پلی گلیسیدیل نیترات-پلی کاپرولاکتون به عنوان پلی ال در بایندر پیشرانه
Binders in composite propellants have a crucial role to affect the physical and thermochemical properties. So it is necessary to choose the binder ingredient appropriately. The suitable binders have a high solid loading, good mechanical and process ability properties. Polycaprolactone due to the polar groups in their structures are able to mix with other nitrate esters. At this point of view, t...
[ 4 ] - تولید ماده دی متیل آمینو اتانول در مقیاس آزمایشگاهی و بررسی پارامترهای مؤثر بر آن
هدف در این پژوهش تولید ماده دی متیل آمینو اتانول و بررسی تأثیر پارامترهای مؤثر بر بازده و خلوص فراورده ی به دست آمده است. برای تولید این ماده از روش دی متیل دار کردن اتانول آمین با استفاده از فرمالدئید آبی، در حضور فرمیک اسید استفاده شد. بررسی نتیجه های به دست آمده نشان می دهد که چهار پارامتر دما...
