1. Application in Engine Compartment: Coping with High Temperature and Vibration
The engine compartment reaches 80-120℃ during operation, with vibration and oil pollution. Nastro in lamina di alluminio protects components here effectively.
1.1 Wire Harness Fixing and Protection: Avoiding Short Circuits and Aging
- Applicable Types: Ignition coil, sensor (per esempio., water temperature, crankshaft position) and fuel injector wire harnesses (2-8mm diameter).
- Operation: Clean wire harness with alcohol and dry. Wrap with tape (10-50larghezza mm) A 1/3 overlap, no air bubbles. Stretch 10%-15% at corners.
- Effetto: Withstands 120℃ continuous/150℃ peak heat. Prevents PVC sheath softening and reduces engine failure risk.
- Caso: Re-wrapping old vehicle wire harnesses cuts idle instability failure rate by over 80%.
1.2 Pipeline Heat Preservation and Sealing: Reducing Loss and Leakage
- Applicable Pipelines: Coolant (16-25mm, rubber/aluminum alloy), fuel return (8-12mm) and vacuum booster (10-15mm) Condutture.
- Heat Preservation: Wrapping in winter keeps coolant 3-5℃ warmer, helping the engine reach operating temperature faster.
- Sigillatura: Wrap 3-5 layers around slightly leaking joints (≤5ml/hour), press 30s per layer. Cover small alloy pipe cracks (≤0.5mm) with tape + high-temperature sealant (≥200℃).
2. Application in Vehicle Interior: Improving Comfort and Stability
The interior needs quietness and firm components. Aluminum foil tape fixes sound insulation cotton and repairs parts without affecting appearance.
2.1 Sound Insulation Cotton Installation: Reducing Noise
- Positions & Specs: See Table 2 for details.
- Steps: Apply glue on cotton back, cut tape to match edges. Stick every 10-15cm at cotton-metal joints, avoid speaker/lock holes (≥2cm distance).
- Effetto: Lowers 60km/h driving noise by 3-5dB, especially tire/road noise.

2.2 Interior Component Fixing: Repairing Looseness
- Applicable Parts: Trim strips (5-15mm), sun visor buckles, seat button covers.
- Metodo: Clean old glue on loose trim (≤5cm), polish back. Stick tape 2cm longer than loose part, press 30s. Wrap 1-2 layers around loose buckles.
- Vantaggi: Silver color matches interior; adheres over 1 year at 20-60℃.

3. Applicazione nel sistema di condizionamento dell'aria: Garantire l'efficienza
Le condutture e gli evaporatori di aria condizionati necessitano di nastro per foglio di alluminio per la conservazione del calore, sigillatura e protezione.
3.1 Preservazione del calore della pipeline: Ridurre la perdita di freddo/calore
- Condutture: Bassa pressione (5-10℃, 12-18mm) e alta pressione (50-70℃, 12-18mm) tubi; Avvolto in cotone PE/gomma (8-15mm).
- Steps: Montare strettamente il cotone, Avvolgere il nastro parallelo alla pipeline (1/2 overlap). Tagliare a forma di ventola a curve, premere giunto 1 minuto.
- Effetto: Si raffredda a 25 ℃ 15%-20% Più veloce; Taglia l'uso di energia di riscaldamento di 10%-12%. Impedisce il gocciolamento della condensa.
3.2 Sigillatura dell'evaporatore: Bloccare la polvere/umidità
- Situazione: Evaporatore (Console all'interno) Ha lacune con guscio da 0,5-1 mm per polvere/umidità.
- Metodo: Rimuovere il rivestimento della console, Lacune pulite. Stick da 5-8 mm di nastro lungo gli spazi vuoti; giunta 45 ° agli angoli. Raschiare il nastro per adattarsi a shell.
- Funzione: Smette di bloccare la polvere pinne, Previene l'odore di muffa e aria condizionata.
4. Applicazione nel corpo esterno: Riparazione e protezione temporanei
Il nastro di foglio di alluminio ripara temporaneamente danni minori e protegge le parti del telaio per la manutenzione professionale in seguito.
4.1 Minor Scratch/Dent Repair
- Damage: Paint scratches (≤0.1mm, ≤10cm), small dents (≤5cm², ≤2mm), no exposed metal.
- Steps: Pulito, dry and polish scratch. Stick tape 2cm larger than damage, premere 1 minuto. Heat dents (50℃, 10S) before pasting.
- Note: Valid 1-3 mesi; need professional paint repair. Ensure oil-free surface.
4.2 Chassis Protection: Avoiding Stone Impact
- Parts & Protezione: See Table 3 for details.
- Metodo: Clean parts, cut 20-30mm tape. Stick every 5cm at edges/hit-prone areas (per esempio., guard front).
- Effetto: Lowers chassis damage rate by over 60%.
