โหมดความล้มเหลวของท่อซิลิโคน & สาเหตุที่แท้จริง

การแนะนำ

Silicone hoses are widely used in automotive, ทางอุตสาหกรรม, and EV applications. อย่างไรก็ตาม, failures can occur if design, materials, or manufacturing are not optimized. Understanding failure modes and root causes is key to long-term reliability.

FMEA

Common Failure Modes

-Cracking & Surface Degradation – Caused by thermal aging and excessive temperature cycles.

-Delamination – Separation between silicone layers or reinforcement under pressure or heat.

-Swelling & Softening – Oil, สารหล่อเย็น, or chemical exposure can reduce mechanical strength.

-Burst or Blow-Off – Insufficient reinforcement or incorrect geometry under pressure.

สาเหตุที่แท้จริง

-Material Incompatibility – Hardness, การยืดตัว, thermal expansion mismatch

-Reinforcement Issues – Poor adhesion or incorrect fiber orientation

-Process Control – Non-uniform vulcanization or incomplete curing

-Combined Stress Aging – Heat, ความดัน, vibration over time

Engineering Prevention

-Carefully matched silicone compounds

-Reinforcement pre-treatment and orientation optimization

-Controlled curing and batch traceability

-Pressure cycling and thermal aging validation

การใช้งานทั่วไป

-Turbocharger hoses

-ลูปการระบายความร้อน EV

-Hydrogen fuel cell air circuits

-Industrial high-temperature hoses

บทสรุป

Silicone hose failure is usually multi-factorial, involving material, การเสริมแรง, and process. HOTOP’s engineering approach ensures hoses remain reliable under complex operating conditions.
