| 目的 改进弹药内表面喷涂方式及涂料种类,解决弹药装药环境适应性高低温贮存裂纹疵病的问题。 方法 采用高压无气喷涂技术进行弹体内表面喷漆,替代原有的空气喷涂。 探讨涂料压力、涂料黏度、喷嘴移动速度等因素对涂层质量的影响,通过正交试验确定最佳工艺参数。 采用直线加速器检测不同漆膜厚度的弹体装药环境适应性裂纹疵病情况。 结果 涂料压力为 65 kg/ cm2,涂料黏度为 30 s,喷嘴移动速度为 50 Hz,喷嘴孔径分别为 0. 51,0. 71 mm 时,弹药内表面漆膜具有较好的外观质量,漆膜厚度及附着力满足要求。 膜层厚度为 180 μm 的弹药经高、低温贮存试验,未出现裂纹。 结论 应用实践证明,高压无气喷涂工艺技术用于弹药卧式自动内表面涂装可行,具有一定的行业推广价值。 |

| Objective To improve the spraying mode and paint variety of internal surface of ammunition, solve the problems of high environment adaptability of ammunition charge and crack flaw due to low-temperature storage. Methods A high pressure airless spray technique was adopted to carry out spray painting of internal surface of ammunition, to substitute the original air spray mode. The effects of factors such as paint pressure, paint viscosity, nozzle movement speed on the coating quality were discussed, and the optimal process parameters were determined by orthogonal experiments. The situation of the environment adaptability of ammunition charge and the crack flaw of paint film with different thickness were tested by linear accelerator. Results The paint film of inner surface of ammunition had good appearance quality, the thickness of paint film and the adhesion met the requirements when the paint pressure was 65 kg/ cm2, the paint viscosity was 30 s, the nozzle movement speed was 50 Hz, the nozzle diameters were 0. 51 and 0. 71 mm, respectively. The ammunition with a paint film of 180 μm thickness did not crack after the high- and low-tem-perature storage tests. Conclusion It was proved by application that the high-pressure airless spray technique used for horizontal automatic inner surface spraying of ammunition was feasible and worthy of spreading in industry. |
