4kg/m³ Ultra-Light Melamine Ua Npuas Ncauj: Lub Teeb acoustic & Thermal Solution rau Rail Transit | SINOYQX
- Kev sib tw hauv Rail Transit Materials
Niaj hnub nimno high-speed rail thiab metro systems ntsib peb qhov teeb meem tseem ceeb:
- Comfort vs. High-Speed
- Thaum ceev tshaj 300 km / h, log-rail thiab aerodynamic suab nrov nce sharply.
- Cov suab nrov hauv tsev tuaj yeem ncav cuag 75-85 dB (A), cuam tshuam cov neeg caij tsheb kev nplij siab thiab kev nyab xeeb ntawm tus neeg tsav tsheb.
- Energy Efficiency vs. Lightweight Design
- HVAC systems account rau 30-40% ntawm tag nrho cov tsheb ciav hlau siv zog.
- Txo lub tsheb hnyav los ntawm tsuas yog 1% tuaj yeem txiav tag nrho lub zog siv los ntawm 0.5 - 0.7%.
- Kev Nyab Xeeb Hluav Taws vs. Cov Kev Cai Ib puag ncig
- Cov ntaub ntawv yuav tsum ua raws li EN 45545-2, DIN 5510, NFPA 130 cov qauv kawm.
- Lawv yuav tsum halogen-dawb, tsis muaj pa luam yeeb, thiab tsis muaj tshuaj lom thaum muaj xwm txheej hluav taws.
- Cov khoom sib piv
| khoom hom | Qhov ceev (kg / m³) | Suab Nkauj Kho Siab | Kev Ntsuas Kub | Kev Tua Hluav Taws Xob | Cov kev txwv |
| Melamine ua npuas ncauj (4kg / m³) | 4 | Wideband α ≈ 0.85 (mid-high zaus) | λ ≈ 0.030–0.035 W/m·K | UL94 V-0, nws tus kheej tua | Tus nqi siab dua me ntsis tab sis superior kev ua tau zoo tag nrho |
| PU ua npuas ncauj (Open-Cell) | 10-40 | ntsis | Nruab nrab | Ua tau yooj yim | Kev laus, kev nyab xeeb hluav taws tsis zoo |
| iav ntaub plaub | 10-80 | zoo heev | zoo heev | Tsis-combustible | Hnyav, plua plav teeb meem, teeb meem installation |
| XLPE Foam | 25-80 | Txom nyem | zoo heev | Flammable / FR qib muaj | Lub suab tsis zoo |
| PET Fiber (Dub) | 15-50 | ntsis | Nruab nrab | Flammable (yuav tsum tau kho FR) | Tsawg durability, txo hluav taws kev nyab xeeb |
📌 Xaus lus:
- PU ua npuas ncauj thiab PET fiber ntau yog tus nqi qis tab sis tsis txaus rau niaj hnub kev nyab xeeb thiab kav ntev.
- Cov iav ntaub plaub ua tau zoo acoustic thiab thermally tab sis ntxiv hnyav hnyav.
- SINOYQX 4kg / m³ melamine ua npuas ncauj tshwj xeeb ua ke ultra-light ceev, wideband suab haum, tsis tshua muaj thermal conductivity, thiab intrinsic nplaim kuj-ua qhov kev xaiv zoo tshaj plaws rau kev thauj mus los.
- Daim Ntawv Thov Cheeb Tsam hauv Rail Transit
- Carbody Phab ntsa & Qab nthab
- Txo lub log-rail thiab aerodynamic suab nrov los ntawm 5-8 dB (A).
- Txhim kho HVAC efficiency los ntawm kev txo cov cua sov hloov mus, txiav lub zog siv los ntawm 5 - 10%.
- Tus Tsav Tsheb Cab Noise Reduction
- Siv rau hauv cov phab ntsa, flooring, thiab qab nthab panels.
- Txo cov suab nrov sab hauv cab los ntawm 6-10 dB (A), txhim kho kev nyab xeeb thiab txo kev qaug zog.
- Underframe & Power Compartments
- Kev khiav hauj lwm ntau: -200 ° C rau + 240 ° C.
- UL94 V-0 nplaim tsis kam, ua raws EN 45545-2 HL3 cov qauv kawm.
- Muab dual tiv thaiv hluav taws + thermal barrier rau cov khoom siv rhiab heev.
- Rooj & Sab hauv Cheebtsam
- Hloov cov tsoos PU ua npuas ncauj nrog 20-30% poob phaus.
- Tsis muaj cov pa phem emissions thaum hluav taws, ua kom cov neeg caij tsheb muaj kev nyab xeeb.
- Kev Lag Luam Trends & Yav Tom Ntej Outlook
- Kev cai nruj dua → Cov qauv thoob ntiaj teb (EN 45545, CRCC, NFPA 130) tau nruj dua.
- Khoom Evolution → PU thiab PET fibers tau raug txiav tawm hauv daim ntawv thov hwm.
- Kev Tsim Kho Yav Tom Ntej:
- Aluminium-laminated composites ntxiv rau kev tiv thaiv thermal.
- Nonwoven composites rau hybrid acoustic-structural daws teeb meem.
- Ua raws li RoHS / REACH cov ntawv pov thawj rau kev lag luam thoob ntiaj teb ib puag ncig.
SINOYQX melamine ua npuas ncauj tsis yog ib yam khoom siv hloov pauv xwb - nws yog ib qho kev daws teeb meem uas hloov pauv kev ua si uas thawb kev thauj mus los ntawm tsheb ciav hlau mus rau kev nyab xeeb dua, sib dua, thiab siv hluav taws xob ntau dua.
