Yakajairika Nyaya Yekudzidza (Ruzha + Insulation)
- nharaunda: 10 m², ukobvu: 15 mm → Vhoriyamu 0.15 m³
- Melamine Foam (4kg/m³): 0.6 kg vs. PU Foam (20 kg/m³): 3.0 kg
- mugumisiro:~80% yakareruka, ruzha rwekabhini inodonha ≥ 4 dB (A)
- Mauto Ndege Noise uye Thermal Siginicha Kuderedzwa
Chidimbu Chekushandisa
Ndege dzehondo dzinoda zvinhu zvinoderedza ruzha rwemukamuri , zvinoderedza simba remagetsi , uye zvinotsungirira mamiriro ekunze akaipisisa. Foam ye 4 kg/m³ melamine inoita izvi pasina kukanganisa mutoro.
Verification & Testing
- Acoustic: NVH bvunzo dzeusimbe, rwendo, uye maneuver
- Kupisa: UL94 V-0 / FAR 25.853 / MIL-STD kuchengetedzwa kwemoto
- Impact Resistance: Chimiro chemutoro / kuvhunduka spectra
- Thermal/IR: ISO 8301 / ASTM C518 + IR siginecha ongororo
- Environmental Durability: Temp cycling, humidity, salt fog
Yakajairika Nyaya Yekudzidza (Ruzha + Mutoro Wekugadzirisa)
- nharaunda: 10 m², ukobvu: 20 mm → Vhoriyamu 0.2 m³
- Melamine Foam (4 kg/m³): 0.8 kg vs. Acoustic Cotton (18kg/m³): 3.6 kg
- mugumisiro: ~ 78% yakareruka, ≥ 5 dB (A) kuderedza ruzha, ~ 3% IR siginicha inodonha
Global Advantages kune Aerospace OEMs
