一、问题的提出引信的包装,目的是便于运输、密封和贮存。但是在过去,引信包装一直存在着不同程度的问题。最早,引信包装盒是用铁盒(见图1)表面喷漆,因其漆膜附着力小,所以在运输过程中,极易因磕碰而损坏漆膜,不能达到防腐的目的。后来改用塑料盒包装,但塑料受环境影响性能变化较大,且易老化。炎热天气,塑料变软;寒冷天气,塑料变硬.易脆裂, First, the question put Fuze packaging, the purpose is to facilitate the transport, sealing and storage. However, in the past, there have been varying degrees of problems with packaging of fuses. The earliest, the fuse box is tin box (see Figure 1) surface paint, because of its paint adhesion, so in the transport process, easily damaged due to bump paint, can not achieve the purpose of preservation. Later, the plastic box instead of packaging, but the plastic by the environmental impact of large changes in performance, and easy to aging. Hot weather, plastic softened; cold weather, harden the plastic. Easy to brittle,
