硝化纤维 Nitrocellulose

(重定向自Gun cotton)

硝化纤维(Nitrocellulose),学名纤维素硝酸酯,也称硝化棉硝基纤维素,通常由棉绒纤维和木浆等纤维材料浸入浓硝酸浓硫酸混合液中制得,多数用于制作发射药。与硝化甘油相比,比较稳定,安全,便于运输。为白色或微黄色棉絮状物,易燃且具有爆炸性,化学稳定性较差,常温下能缓慢分解并放热,超过40°C时会加速分解,放出的热量如不能及时散失,会造成硝化棉温升加剧,达到180°C时能发生自燃。硝化棉通常加乙醇或水作湿润剂,分别称作硝化棉酒棉或硝化棉水棉。一旦湿润剂散失,极易引发火灾。如果在装卸作业中存在野蛮操作,发生硝化棉装箱包装破损、硝化棉散落的情况。试验表明,包装破损时,在50°C下2小时乙醇湿润剂会全部挥发散失。易于导致仓储自燃。
