硅胶干燥剂

Silica gel desiccant is a highly porous granular substance made up of silica beads that adsorb moisture within an enclosed space. Silica gel has a very large surface area and is effective in controlling humidity while protecting products from moisture damage during storage or shipping. Silica gel desiccants come in variety of form factors including packets (breathable), canisters or loose fill. Silica gel is non-toxic, chemically inert, and stable well above and below normal ambient temperatures.
 
Among the most used desiccants, silica gel is our most popular desiccant in the electronics, pharmaceuticals, food packaging and consumer products markets. Some benefits are that it is reusable (can be reactivated by heating), dust-free for sensitive applications, and comes in a variety of shapes. Silica gel with moisture indicative blue/orange beads allows for visual monitoring of humidity and can provide reliable protection and reassurance to consumers while meeting FDA/ISO safety standards.

Applications of Silica Gel Desiccants

包装与运输

包装与运输

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。

食品工业

Permitted for direct food contact (FDA, EU), silica gel protects dry foods, such as spices, snacks, and supplements, by adsorbing moisture during storage. Silica gel prevents clumping, microbial growth, and loss of flavor and texture by adsorbing moisture within sealed packaging. Silica gel is non-toxic, non-reactive and odor-free, and extends shelf life without changing the taste of the food product. You can design your own silica gel sachets that can fit inside packages, jars or pouches, making it a highly versatile, and indispensable tool for preserving quality for the life cycle of the product, from production to consumption.

Silica gel protects precision automotive parts (sensors, engine components) during warehousing and shipping. When placed in packaging to the component specific enclosures, it prevents oxidation and condensation and also electrical failures due to humidity. Silica gel is thermally stable (−40°C to 150°C) for performance in extreme conditions, the non-abrasive beads do not damage polished surfaces, and it absorbs excess humidity.
