纳米CL-20炸药含能墨水的直写规律
Direct Writing Rule of Nano CL-20 Explosive Energetic Ink
摘要
Abstract
Aiming at the micro-detonation sequence of MEMS initiators,the direct writing characteristics of CL-20 explosive ink composed of nano CL-20 explosive,binder system (including the binder and the solvent)and other additives based on the direct writing technique were studied.Three kinds of energetic inks were prepared.The influence rule of direct writing pressure,jet diameter,direct writing height and ink viscosity on the direct writing process was analyzed.The results show that with ink viscosity increasing,the direct writing line width reduces and the reduction amplitude increases,but when the viscosity is too high,it will affects the uniformity of line width. The uneven phenomenon of line width appears at nozzle height of 0.50 mm or 0.75 mm for formula Ⅰ and nozzle height of 0.75 mm for formula Ⅲ.Formula Ⅱ with stable direct writing line width is suitable for direct writing charge.Printing line width of CL-20 ink increases significantly when the pressure in nozzle increases.With increas-ing the pressure from 100 kPa to 200 kPa,the line width increases by about 2.5 times.With increasing the inner diameter of nozzle,the direct writing line width increases obviously and the increase amplitude is more and more. The direct writing line width of ink reduces with the nozzle height increases.When direct writing line width is more than 1 285μm,air bubbles form when ink solidifies.Therefore,line width in the direct writing process should be controlled to avoid the air into the ink.关键词
