Download or read book General Chemistry Technical Note No. 61--new Developments in Plastic Bonded Explosives written by and published by . This book was released on 1961 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two new explosives are under development at Lawrence Radiation Laboratory (LRL) which show considerable promise as replacements for PBX 9404 (and also PBX 9010). Three primary considerations have guided us in the development of these explosives. Compared to PBX 9404 we have sought a significant decrease it sensitivity, a substantial gain in mechanical properties and as little loss in energy and detonation velocity as possible. While testing is not complete on these materials and probably won't be for quite some time sufficient information is available to warrant a complete status report at this time. An index of the topics covered herein is: Formulations and Raw Materials; Molding Powder; Explosive Performance; Sensitivity; Thermal Stability; Compatibility; Mechanical Properties; Machinability; Pressability; and Comparison of the Two Materials.

Book Synopsis Development of Inert Simulants for Castable Plastic Bonded Explosives by : Wayne L. Elban
Download or read book Development of Inert Simulants for Castable Plastic Bonded Explosives written by Wayne L. Elban and published by . This book was released on 1971 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes the development and evaluation of inert simulants for two new castable explosives developed, namely, PBXW-106 and PBXN- 103. The simulants closely duplicated the loaded density, processability, machinability, ultimate tensile strength and cured hardness of each explosive. Each simulant has a binder system consisting of an oil extended, hydroxyl- terminated polybutadiene resin that reacts with toluene diisocyanate to form a solid polyurethane polymer. Using the basic solids-loaded polymer system selected for the work it is possible to formulate a simulant with a density that would closely match the density of most explosives of military interest.

Book Synopsis Plastic Bonded Explosive (PBX) Particle Size Distribution (PSD) Measurements Using an Image Analysis System by :
Download or read book Plastic Bonded Explosive (PBX) Particle Size Distribution (PSD) Measurements Using an Image Analysis System written by and published by . This book was released on 2003 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The slurry process for producing plastic bonded explosives (PBX) has been used for many years. However, until recently the mechanisms involved have not been studied quantitatively to determine the effects of the various control variables. Recently, the effects of operating variables on the final product have been studied; however, no attempt was made to measure particle growth during the slurry process. This study applies an image analysis tool to measure particle size distributions (PSDs) during the slurry process to produce PBX 9501, a specific formulation used in nuclear weapons. The observed PBX 9501 slurry behavior leads away from the typical population balance description of agglomeration, that is, a discrete particle-particle coalescence mechanism. The behavior observed in these experiments indicates that the initial state of the system contains a number of smaller particles clustered together. The cluster then coalesces into a large particle as solvent is removed and the slurry continuously mixed. Other small fragments are picked up and a relatively small amount of growth is observed. A mass transfer model adequately describes solvent removal, and an empirical model is developed to describe the growth behavior in terms of measured process variables. The image system is applied to dried molding powders. The PSD measurement results of the PBX 9501 library lots, historic samples set aside as PBX 9501 lots were accepted from the manufacturer, are also discussed and analyzed. A correlation analysis was conducted to find relationships between the measured PSD and other properties such as bulk density and pressed densities. While no significant correlation was found between the measured PSD and averaged bulk densities for the library lots, significant correlations are found between the measured PSD and pressed density. The final part of the study was to scale-up the PSD measurement capability. Since the large-scale processes are not yet operational, this work makes recommendations for future consideration. Also, some additional small-scale experiments are recommended as well as improvements to the smallscale experimental apparatus.

Ontwikkeling Van de Procedure). written by and published by . This book was released on 1994 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: A further development of the procedure based on pyrolysis-gas chromatography (Py-GC) for the characterization of plastic bonded explosives (PBX's) is described. After grinding, the PBX samples were pressed on a pyrolysis wire followed by Py-GC analysis. The peak areas obtained were normalized and submitted to multivariate data analysis. The use of principal component analysis (PCA) was tested on 5 samples which differed slightly in composition and age. The results were promising and showed that PCA is a powerful tool for the differentiation between PBX samples. The pressure by which the samples were pressed on the pyrolysis wire appeared to be an important parameter. This parameter was optimized together with the pyrolysis temperature and the amount of sample. The optimization experiment was carried out with 2 PBX samples which differed only in crosslink density. It turned out that it was difficult to find optima in the parameters resulting in a maximal difference between the 2 samples. The following settings of the parameters were selected: 5.2 tonnes, 75 mg and 610 C.

Available in PDF, EPUB and Kindle. Book excerpt: Pressed plastic-bonded explosives, PBXs, are commonly used by defense and private industry. PBX 9501 is composed of HMX crystals held together with a plastic binder 'softened' with plasticizers. The detonation behavior of any explosive is very dependent upon its density, with the desire to have a uniform, high density throughout the explosive component. A parametric study has been performed pressing PBX 9501 hydrostatically and uniaxially. The effects of several pressing parameters on the bulk density and density profile, as well as mechanical properties, have been measured. The parameters investigated include pressure, temperature, number of cycles, dwell time, rest time, sack thickness, and particle distribution and size. Density distributions within the pressed explosives were also compared.
