Desecante para automoción

Automotive desiccants industry are commercial grade sorbents that remove moisture to help protect fragile automotive parts/systems from moisture related damage. Moisture problems can arise during production, shipping and storage and are critical to reliable and durable automotive components (fuel systems, sensors, headlights, ECUs, airbags, etc.). Desiccants assist moisture removal from sensitive parts/systems to overcome corrosion, failures, and deterioration. It is imperative that automotive OEMs manage the environments in which their products are stored, since contaminants must be removed to comply with the quality and safety standards of the automotive industry. Automotive OEMs trust that controlling the moisture within their sealed environment will help eliminate customer and regulatory problems associated with the storage of moisture sensitive goods.
Automotive industry desiccants are in various forms including silica gel packets, clay/bentonite desiccants, molecular sieves, and humidity indicator cards to satisfy various moisture control needs. Silica gel is best suited for moderate humidity levels, while molecular sieves are deep dry in circumstances requiring high precision. Their value in the automotive industry relies on their broad moisture absorption efficiency, mechanical stability under thermal temperature fluctuations, and safe & easy handling during production and logistics applications. Using automotive industry desiccants helps reduce warranty claims, extend useful life, and maintain consistent performance of regulated moisture sensitive supply chain requirements.

Embalaje y transporte Desecante

Los desecantes de gel de sílice son necesarios para proteger los productos en tránsito y almacenamiento. Los desecantes de gel de sílice se envasan en bolsitas o botes transpirables y controlan la humedad en contenedores de transporte, cajas de cartón y cajones. El gel de sílice absorbe la humedad del aire ambiente y evita la condensación, el moho, la corrosión del metal y los daños en materiales sensibles a la humedad. El gel de sílice es perfecto para la electrónica, la maquinaria, el arte y los productos de papel, para garantizar que los artículos lleguen en las condiciones adecuadas, independientemente del cambio climático que se haya producido durante la logística del transporte mundial.

El gel de sílice es bien conocido por sus propiedades de control de la humedad en la fabricación y el almacenamiento de productos electrónicos. La protección adecuada de los componentes sensibles es fundamental, especialmente en el embalaje de artículos como placas de circuitos, semiconductores o dispositivos ópticos. Mediante el uso de gel de sílice en envases sellados, o armarios sellados, los componentes electrónicos se mantienen en entornos de baja humedad. Esto reduce los riesgos de daños imprevistos en los componentes por oxidación, cortocircuitos eléctricos y fallos de rendimiento de cualquier tipo. Las propiedades del gel de sílice, no corrosivo, exento de polvo y seguro para el contacto directo con piezas delicadas, garantizan un envío y manipulación seguros desde fábrica sin abrir.

El gel de sílice proporciona una prevención vital contra la humedad en frascos de medicamentos, kits de diagnóstico y como componente del envasado de dispositivos médicos. El gel de sílice cumple los requisitos de la FDA y la farmacopea, y protege comprimidos, cápsulas y reactivos de laboratorio tanto de la degradación causada por la humedad como de niveles elevados de humedad. Y lo que es más importante, el gel de sílice actúa estabilizando los niveles de humedad en entornos sellados, prolongando la vida útil, la esterilidad y la eficacia o viabilidad terapéutica. Los paquetes de gel de sílice no sólo funcionan bien para suavizar los cambios de humedad, sino que también son transparentes, lo que permite una inspección visual. Además, los paquetes de gel de sílice sin cobalto no plantean problemas de toxicidad en aplicaciones deliberadamente sensibles.
