Foam Melamine Ultra-Aotrom 4kg/m³: Fuasgladh Fuaimneach is Teirmeach Aotrom airson Còmhdhail Rèile | SINOYQX
- Dùbhlain ann an Stuthan Còmhdhail Rèile
Tha trì dùbhlain chudromach mu choinneamh siostaman rèile is metro àrd-astar an latha an-diugh:
- Comhfhurtachd an aghaidh astar àrd
- Aig astaran os cionn 300 cilemeatair san uair, bidh fuaim nan cuibhlichean-rèile agus fuaim aerodynamic ag èirigh gu mòr.
- Faodaidh ìrean fuaim a’ chabain ruighinn 75–85 dB (A), a’ cur bacadh air comhfhurtachd luchd-siubhail agus sàbhailteachd an draibhear.
- Èifeachdas Lùtha an aghaidh Dealbhadh Aotrom
- HVAC systems account for a substantial share of train auxiliary energy use, depending on vehicle design and operating conditions.
- Reducing vehicle weight by just 1% can cut overall energy use by a system-dependent amount that requires route and vehicle energy modelling.
- Sàbhailteachd Teine an aghaidh Riaghailtean Àrainneachdail
- Feumaidh stuthan gèilleadh ri TS EN 45545-2, DIN 5510, NFPA 130 inbhean.
- They should be assessed for applicable substance restrictions, smoke and combustion-product requirements using the appropriate tests.
- Coimeas Stuth
| Seòrsa stuth | Raon dùmhlachd (kg/m³) | Coileanadh fuaimneach | Coileanadh Teirmeach | Fuasgladh Smàlaidh | Crìochan |
| Foam melamine (4kg/m³) | 4 | Bann-leathann α ≈ 0.85 (tricead meadhanach-àrd) | λ ≈ 0.030–0.035 W/m·K | UL94 V-0, fèin-mhùchadh | Installed cost and performance depend on the grade and assembly |
| Foam PU (Ceall Fosgailte) | 10-40 | Meadhanach | cuibheasach | lasanta | Aosmhorachd, droch shàbhailteachd teine |
| Clòimh ghlainne | 10-80 | Sònraichte | Sònraichte | Neo-losgaidh | Trom, cùisean duslach, duilgheadas stàlaidh |
| Foam XLPE | 25-80 | Dhona | Sònraichte | Ìrean lasanta/FR rim faighinn | Droch ghlacadh fuaim |
| Fibre PET (Dubh) | 15-50 | Meadhanach | cuibheasach | Lasanta (feumaidh làimhseachadh FR) | Seasmhachd cuibhrichte, sàbhailteachd teine nas ìsle |
📌 Co-dhùnadh:
- PU and PET materials have multiple grades; select based on relevant fire, acoustic, mechanical and durability tests.
- Glass wool is an established acoustic and thermal option; compare total installed mass and system performance for equivalent specifications.
- SINOYQX 4 kg/m³ melamine foam offers a low-density candidate for acoustic and thermal evaluation; rail approval requires grade- and assembly-specific fire, smoke, vibration and durability qualification.
- Raointean Tagraidh ann an Còmhdhail Rèile
- Ballachan is Mullaichean Bodhaig Chàraichean
- Potential acoustic benefit should be measured on the specified carbody assembly; no universal 5–8 dB(A) reduction is claimed.
- Thermal performance depends on insulation design and operating conditions. Energy savings require vehicle-level calculations and validation.
- Lùghdachadh Fuaim Cab an Draibhear
- Air a chur an sàs ann am ballachan, làir, agus pannalan mullaich.
- Cab noise reduction and driver comfort depend on the complete assembly and must be evaluated through representative acoustic tests.
- Roinnean Fo-fhrèam & Cumhachd
- Operating temperature limits must be confirmed for the exact grade, exposure duration and rail assembly.
- Any UL94 or EN 45545-2 result must be confirmed from relevant grade- and end-use-specific test documentation; an UL94 grade does not independently establish EN 45545-2 HL3 compliance.
- Thermal or acoustic insulation may be evaluated; any fire-barrier function requires a separately qualified complete assembly.
- Suidheachain & Pàirtean Taobh a-staigh
- Relative weight depends on the density, thickness, attachments and equivalent performance requirements of the final rail interior assembly.
- Combustion products and smoke toxicity must be evaluated under applicable rail fire requirements; non-toxic smoke must not be assumed.
- Claonaidhean Gnìomhachais & Ro-shealladh san àm ri teachd
- Riaghailtean nas teinne → Tha inbhean cruinneil (EN 45545, CRCC, NFPA 130) a’ sìor fhàs teann.
- Meudachadh stuthan Tha snàithleanan PU agus PET gan cuir às mean air mhean ann an tagraidhean àrd-inbhe.
- Leasachadh ri teachd:
- Stuthan co-dhèanta air an dèanamh le alùmanum airson dìon teirmeach a bharrachd.
- Stuthan co-dhèanta neo-fhighte airson fuasglaidhean structarail is fuaimneach measgaichte.
- Gèilleadh ri teisteanasan RoHS/REACH airson margaidhean àrainneachdail cruinneil.
SINOYQX foam melamine chan e dìreach stuth ath-chuir a th’ ann—’s e lightweight material option for rail acoustic and thermal designs, subject to applicable engineering and fire-safety qualification.
