Study of Protective Apparel on Hydroxyl Ammonium Nitrate(HAN) Propellant / 医疗卫生装备

ABSTRACT

Objective To study a protective apparel with protective suit and protective mask in order to protect the operators using new HAN propellant in the course of storage, transportation and filling-up. Methods According to the character of it, polyurethane-coated (PU)polyester fabric was applied in the main part of protective suit and mask, and then anti-fog technology to deal with PU as window material. Results The performance test and probation evaluation of the protective apparel were met relevant standards of the technical specifications. Conclusion Through reasonable structure designing, the defects in the protective apparel were overcome such as bad permeability and large load. The protective apparel was characteristized by portable, comfortable, practical and so on. Furthermore, it enriches the protective system for the liquid propellant.
