霉菌对军用枪支的侵蚀与防治

Corrosion and Control of Mould against Military Firearms

为了有效保存军用枪支,防止霉菌的侵蚀危害,用人工接种培养方法,将军标指示菌接种到枪支上.第 1 组置于加防霉剂和干燥剂密封袋中,第 2 组置于不加防霉剂和干燥剂敞口袋中.在温度 (30±1) ℃ ,湿度(95±5)%交替变化的条件下对军用枪支连续进行试验.结果表明,第 1 组样品长霉极少,危害小,长霉面积仅为0.103%～0.304% .而第 2 组样品长霉面积大,危害严重,长霉面积为11.37%～22.94%,是第 1 组的 110.4～133.4 倍.因此,选择适合的防霉剂和干燥剂在密封条件下,有利于抑制霉菌生长,是防止霉菌对军用枪支危害的有效方法.

Military standard indication moulds were inoculated to military firearms and divided into two groups. One group was put in sealed bag added with preservative antiseptic and desiccant, the other group was put in opened bag added no preservative antiseptic and desiccant. And the test was continuously carried out under alternative changing conditions of （30±1）℃ and humidity of （95±5） % . The results showed that the mould growing in the first group＇ s sample was very few, about 0. 103 % -0. 304 % of the total area; however the area in the second group＇s sample was 11.32 %-22.94 % of the total, that is 110-133.4 times as much as the first group. Therefore, the sealed conditions and proper choice of preservative antiseptic and desiccant are conducive to the inhibition of the mould growth, and is effective method to prevent military firearms from mould harm.
