常见问题
包装与运输干燥剂
硅胶干燥剂是在运输和储存过程中保护产品的必需品。硅胶干燥剂包装在透气的小袋或罐中，用于控制运输集装箱、纸箱和板条箱中的湿度。硅胶能吸收环境空气中的水分，防止冷凝、发霉、金属腐蚀以及对湿度敏感的材料的损坏。硅胶非常适合电子产品、机械、艺术品和纸制品，无论全球物流运输过程中发生何种气候变化，都能确保物品在正确的状态下运抵目的地。
电子行业
硅胶因其在电子制造和储存中的防潮特性而闻名。适当保护敏感元件至关重要，尤其是在包装电路板、半导体或光学设备等物品时。通过在密封包装或密封柜中使用硅胶，可将电子产品保存在低湿度环境中。这就降低了因氧化、电气短路和各种性能故障而对元件造成意外损坏的风险。硅胶具有无腐蚀性、无灰尘、可安全地与精密部件直接接触等特性，可确保工厂在未开封的情况下进行安全的运输和处理。
制药业
硅胶是药瓶、诊断试剂盒和医疗器械包装的重要防潮成分。硅胶符合 FDA 和药典的要求，可保护药片、胶囊和实验室试剂，防止受潮降解和湿度升高。重要的是，硅胶能稳定密封环境中的湿度水平，延长保质期、无菌性和治疗效果或存活率。硅胶包不仅能很好地平滑湿度变化，而且是透明的，可以进行目视检查。此外，不含钴的硅胶包在刻意敏感的应用中不会产生毒性问题。
