4kg/m³ Ultra-Chiedza Melamine Foam: Yakareruka Acoustic & Thermal Solution yeRail Transit | SINOYQX
- Matambudziko muRail Transit Materials
Mazuva ano high-speed njanji uye metro masisitimu anotarisana nematambudziko matatu akakosha:
- Comfort vs. High-Speed
- Pakumhanya kwepamusoro pe300 km/h, vhiri-rail uye aerodynamic noise inokwira zvakanyanya.
- Kabhini ruzha mazinga anogona kusvika 75–85 dB(A), kukanganisa kugadzikana kwevatyairi uye kuchengetedzwa kwemutyairi.
- Kushanda Kwesimba vs. Lightweight Design
- HVAC masisitimu anoverengera 30-40% yehuwandu hwekushandisa simba rechitima.
- Kuderedza huremu hwemotokari ne1% chete kunogona kuderedza kushandiswa kwesimba rose 0.5 - 0.7%.
- Fire Safety vs. Environmental Regulations
- Zvishandiso zvinofanirwa kuenderana EN 45545-2, DIN 5510, NFPA 130 mitemo.
- Vanofanira kuva halogen-isina, yakaderera utsi, uye isina chepfu panguva yezviitiko zvemoto.
- Kuenzanisa Kwezvinhu
| Material Type | Density Range (kg/m³) | Acoustic Performance | Thermal Performance | Fire Resistance | Nokuremara |
| Melamine Foam (4kg/m³) | 4 | Wideband α ≈ 0.85 (yepakati-yepamusoro freq) | λ ≈ 0.030–0.035 W/m·K | UL94 V-0, kuzvidzima | Mutengo wakakwira zvishoma asi wepamusoro pese-kutenderera kuita |
| PU Foam (Vhura-Sero) | 10-40 | eresera | pakati nepakati | Zvinopisa | Kuchembera, kusachengeteka kwemoto |
| Girazi Wool | 10-80 | Excellent | Excellent | Isingatsve | Heavy, huruva nyaya, installation kuoma |
| XLPE Foam | 25-80 | murombo | Excellent | Anopisa / FR mamakisi aripo | Kusanzwa zvakanaka kwenzwi |
| PET Fiber (Dema) | 15-50 | eresera | pakati nepakati | Inopisa (inoda kurapwa kweFR) | Kugara kwakaganhurirwa, kuderera kwekuchengetedza moto |
📌 Mhedziso:
- PU furo uye PET faibha inodhura-inodhura asi haina kukwana kuchengetedzeka kwemazuva ano uye kusimba zvinodiwa.
- Wool yegirazi inoita zvakanaka zvinonzwika uye nekushisa asi inowedzera huremu hwakanyanya.
- SINOYQX 4kg/m³ melamine furo zvinosanganiswa zvakasiyana Ultra-light density, wideband sound absorption, low thermal conductivity, uye intrinsic flame resistance.-ichiita kuti ive sarudzo yakadzikama yekufambisa njanji.
- Nzvimbo dzekushandisa muRail Transit
- Carbody Walls & Ceilings
- Inoderedza vhiri-rail uye aerodynamic ruzha ne 5–8 dB(A).
- Inovandudza kushanda kweHVAC nekudzikisa kupisa kupisa, kucheka kushandiswa kwesimba ne 5 - 10%.
- Mutyairi Cab Noise Kuderedza
- Inoshandiswa mumadziro, pasi, uye sirin'i mapaneru.
- Inoderedza mukati mecab ruzha ne 6–10 dB(A), kuvandudza kuchengeteka uye kuderedza kuneta.
- Underframe & Power Compartments
- Inoshanda huwandu: -200 ° C kusvika + 240 ° C.
- UL94 V-0 murazvo kuramba, inoenderana EN 45545-2 HL3 mitemo.
- Inopa mbiri kudzivirira moto + thermal barriers kune midziyo yakaoma.
- Zvigaro & Zvemukati Zvikamu
- Inotsiva yechinyakare PU furo ne 20-30% kuderedza uremu.
- Hapana huturu hwehutsi hunobuda panguva yemoto, kuve nechokwadi chekuchengetedzwa kwevatyairi.
- Indasitiri Maitiro & Remangwana Outlook
- Mitemo Yakasimba → Zviyero zvepasi rose (EN 45545, CRCC, NFPA 130) zviri kuwedzera kuomarara.
- Material Evolution → PU uye PET mafiibhi ari kubviswa mukutanga maapplication.
- Kubudirira Kwamangwana:
- Aluminium-laminated composites yekuwedzera kuchengetedzwa kwemafuta.
- Nonwoven composites ye hybrid acoustic-structural solutions.
- Kutevedzera RoHS/REACH certification yemisika yepasirese yezvakatipoteredza.
Foam yeSINOYQX melamine haisi yekutsiva chete—imhinduro inoshandura zvinhu zvese inosunda nzira dzechitima kuenda kumasisitimu akachengeteka, akareruka, uye anoshandisa simba shoma.
