Miao","doi":"10.22211/cejem/154975","DOIUrl":"https://doi.org/10.22211/cejem/154975","url":null,"abstract":": To explore the influence rule of octogen ( HMX ) solid content , system temperature , HMX particle size , HMX particle gradation and functional additives etc.on the rheological properties of 2 , 4⁃dinitroanisole ( DNAN ) /HMX suspensions , the appar⁃ ent viscosity of DNAN/HMX suspensions under different material state conditions was investigated by a digital viscometer. Re⁃ sults show that the suspension presents Newtonian fluid characteristics when the solid content is 3%. Apparent viscosity of the suspension can be described with Ostwald⁃deWaele model when the HMX solid content is 12%-30% , and the value of non⁃ Newton index n is decreased from 0.842 to 0.374. The influence of temperture on the apparent viscosity can be described by the Arrhenius equation when the temperture is in the range of 95-116 ℃ , and the activation energy E a increases from 25.97 kJ ∙ mol -1 to 30.17 kJ ∙ mol -1 . The apparent viscosity decrases as the particle size increases. When the particle gradation ratio of 999.5 μ m particle size to 132.6 μ m is 2 ∶ 1 , the apparent viscosity reaches the minimum and the solid content is up to 80%. Functional ad⁃ ditives N ⁃methyl⁃4⁃nitroaniline ( MNA ) and tri ( β chloroethyl ) phosphate ( CEF ) make the apparent viscosity of the suspensions decrease , while dehydrated sorbitol monostearate polyoxyethylene ether ( Tween 60 ), microcrystalline wax⁃80 ( MV80 ), cellu⁃ lose acetate butyrate ( CAB ), and thermoplastic polyurethane -5720 ( TPU 5720 ) make the the apparent viscosity of the suspen⁃ sions increase.","PeriodicalId":9679,"journal":{"name":"Central European Journal of Energetic Materials","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41409248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
