To improve the plasticization quality and process safety of Modified Double-Base (MDB) propellants during the calendering process. This study. using actual physical parameters of MDB propellant. a three-dimensional thermo-fluid coupled model was developed to investigate the effects of process parameters on the heat and mass transfer behavior of MDB materials during the calendering pro... https://iguanasellers.shop/product-category/calligraphy-set/
