METHOD OF CREATING ANTISTICK COATING ON FORMING FIXTURE FOR BLENDED SOLID FUEL CHARGES OF ROCKET ENGINE

摘要

FIELD: rocked fuels. SUBSTANCE: method is accomplished by spraying, immersion, or brushing of antistick composition on cleaned and degreased surface of fixture, said composition being solution of perfluoro-polyester-acid (6MFK-180) in 4: 1 mixture of 1,2-difluorotetrachloroethane and 1,2,2- trifluorotetrachloroethane. Coating is deposited in 2-5 layers observing ageing between depositions of layers for 5-15 min at 15-35 C. EFFECT: enabled creation of small-thickness coating with improved antistick properties. 1 tbl
