Secure Power, Swift Connections
L'environnement de production de l'industrie chimique peut être décrit comme un « site de test sévère » pour les borniers. Des fluides corrosifs tels que l'ammoniac et le chlore imprègnent l'air, une distillation à haute température alterne avec des rinçages fréquents et il existe une double contrainte de normes antidéflagrantes et de propreté. Les terminaux ordinaires présentent souvent des problèmes fréquents tels que la corrosion, le vieillissement ou les fuites dans de tels environnements, constituant ainsi des dangers potentiels cachés pour la sécurité de la production.
High-purity H62 brass is used as the base material, with the surface undergoing multi-layer electroplating: a 5μm nickel underlayer to enhance adhesion, a 3μm palladium-nickel alloy middle layer to resist acids and alkalis, and a 0.2μm gold top layer to improve conductivity. For scenarios frequently exposed to chlorine, sulfur, and other media, 316 stainless steel terminals are selected, which form an oxide film through passivation treatment, achieving a salt spray resistance of over 1000 hours, suitable for acid-base storage tanks, reaction kettles, and other equipment.

An IP67 overall sealing structure is adopted, with fluororubber sealing rings (chemically corrosion resistant) at terminal interfaces, combined with thread-locking connections to prevent liquid chemicals from infiltrating. The wiring cavity is filled with epoxy resin potting compound to form secondary protection, ensuring no leakage failures in scenarios with frequent spray cleaning or condensation (such as cleaning sections).
Terminal designs comply with explosion-proof standards such as ATEX and IECEx. A reinforced insulation layer (thickness ≥1mm) is set between metal components and plastic shells to avoid electrostatic sparks. A misinsertion prevention structure (keyway guidance) is adopted to prevent short circuits caused by wrong wiring. Each batch of products passes the withstand voltage test (AC 2500V for 1min) and ground continuity test, adapting to the strict safety requirements of chemical explosion-proof areas.
