In this study, the curing characteristics of commonly used Hydroxyl terminated polybutadiene(HTPB)-based solid propellant according to the curing temperature and Equivalent ratio change were investigated. In addition, the effect of curing reaction according to their ratio and content in the Triphenyl bismuth(TPB), Maleic anhydride(MA) and Magnesium oxide(MgO) catalyst systems was confirmed. Finally, moisture was added for each propellant mixing process to check the effect of moisture on propellant curing. 본 연구에서는 일반적으로 사용하는 Hydroxyl terminated polybutadiene(HTPB)계 고체 추진제의 경화 온도와 당량비 변경에 따른 경화 특성을 고찰하였다. 또한, Triphenyl bismuth(TPB), Maleic anhydride(MA) 그리고 Magnesium oxide(MgO) 촉매 시스템에서 이들의 비율 및 함량에 따른 경화 반응 영향도 확인하였다. 마지막으로 추진제 혼화 시 각 공정 별 수분을 투입하여 수분이 추진제 경화에 끼치는 영향을 확인하였다.

Objetive : The cold feeling disease is feeling a cold at normal temperature in specific part of body and it can be felt by oneself and the others. This disease let the person who has the disease take various inconvinience in daily life but they don't take any specific care and actucally there are not efficient care. In this study we took Tae-gye(KI3) which is one of the nine point that circulating energe to whole body(回陽九針穴) and observe the efficiency conpare with non acupoint Methord : We used infra-red thermometer to measure the temperature of hand and arm. Acupuncture is treated using Park-sharm device for double-blinding test. Temperature of PC8 is compared with LU4 for measure the coldness of hand. Results : Taking the temperature of Before-state, average temperature of PC8 is lower then LU4 at 0.3℃ degree. Right about acupuncturing, temperature of PC8 got lower at 0.238℃ degree comparing LU4 in treatment group and , got higher at 0.5℃ degree in control group, but both of them have no significance(p>0.05) During the acupuncturing, temperature of PC8 got higher at 0.388℃ degree then LU4 in treatment group and got higher at 0.975℃ degree in control group, but both of them have no significance(p>0.05). After remove the acupuncture, temperature of PC8 got lower at 0.013℃ degree then LU4 in treatment group and got higher at 0.713℃ degree in control group, but both of them have no significance(p>0.05). In control group, the differences of change are very intense for each grade and they had large standard deviation. In treatment group the differences are decreased gradually and they had small standard deviation(SD=0.424) compare with control group (SD=0.723) but there are no significant difference. Conclusion : The results suggested that KI3 can decrease the difference of temperature between PC8 and LU4, and reduce the coldness of hand. After this, study with more group is needed to verify the possibility.
