Hướng dẫn lựa chọn cốt thép

– Polyester / Aramid / Nomex

Giới thiệu

Có vải polyester ở giữa các lớp ống silicon. Vải ống silicone có thể hoạt động như một vật gia cố cho ống silicone. chất liệu vải luôn là polyester. nó luôn được xếp lịch cùng với cao su ống silicon.

Reinforcement is critical to sức mạnh cơ học, sức chịu đựng áp lực, và độ ổn định kích thước. HOTOP provides guidance on material selection based on application needs.

Common Reinforcement Types

»Polyester – Good flexibility, medium strength, general automotive and industrial use. Working temperature -50C to +180C.

»Aramid– High tensile strength, excellent thermal stability, for high-pressure or turbo applications, high-temperature working silicone hose option.Working temperature -50C to +280C.

»Nomex– High heat resistance, fire retardant, for extreme temperature or hydrogen

applications.Working temperature -50C to +300+C.

Material Selection Guidelines

»Pressure Requirements – Higher pressure → stronger fibers (Aramid, Nomex)

»Temperature Range – High temp → Nomex or Aramid

»Flexibility Needs – Tight bends → Polyester preferred

»Chemical Exposure – Ensure fiber compatibility with silicone and fluids

HOTOP Engineering Considerations

»Multi-ply reinforcement design for optimal pressure resistance

»Fiber orientation tuned for vibration and fatigue resistance

»Bonding to silicone compound carefully controlled

Ứng dụng điển hình

»Turbocharger hoses → Aramid

»EV cooling loops → Polyester

»Hydrogen fuel cell hoses → Nomex or Aramid

»High-temperature industrial hoses → Nomex

Phần kết luận

Reinforcement selection is essential for silicone hose performance. HOTOP engineers design application-specific reinforcement to ensure durability, tính linh hoạt, and reliability.
