4kg/m³ I-Ultra-Light Melamine Foam: Isixazululo Esilula Se-Acoustic & Thermal Sokuthutha Kaloliwe | SINOYQX
- Izinselelo Ezintweni Zokuthutha Ngololiwe
Amasistimu wesimanje wesitimela esinesivinini esikhulu kanye ne-metro abhekene nezinselelo ezintathu ezibalulekile:
- Comfort vs. High-Speed
- Ngejubane elingaphezu kuka-300 km/h, i-wheel-rail nomsindo we-aerodynamic ukhuphuka kakhulu.
- Amazinga womsindo wekhabethe angafinyelela 75–85 dB(A), okuphazamisa ukunethezeka kwabagibeli kanye nokuphepha komshayeli.
- Ukusebenza kahle kwamandla vs. Idizayini engasindi
- Amasistimu e-HVAC alandisa 30–40% wesamba sokusetshenziswa kwamandla ezitimeleni.
- Ukunciphisa isisindo semoto ngo-1% nje kunganciphisa ukusetshenziswa kwamandla sekukonke I-0.5-0.7%.
- Ukuphepha Komlilo vs. Imithetho Yemvelo
- Izinto ezibonakalayo kufanele zihambisane EN 45545-2, DIN 5510, NFPA 130 amazinga.
- Kufanele babe njalo ayinayo i-halogen, intuthu ephansi, futhi engenabuthi ngesikhathi semicimbi yomlilo.
- Ukuqhathanisa Kwezinto
| Uhlobo Material | Ububanzi Bokuminyana (kg/m³) | Ukusebenza kwe-Acoustic | Ukusebenza Okushisayo | Ukuphikiswa Komlilo | Ukulinganiselwa |
| I-Melamine Foam (4kg/m³) | 4 | I-Wideband α ≈ 0.85 (imvamisa ephakathi nendawo ephezulu) | λ ≈ 0.030–0.035 W/m·K | I-UL94 V-0, ukuzicisha | Izindleko eziphakeme kancane kodwa ukusebenza okuphezulu kwawo wonke |
| I-PU Foam (Open-Cell) | 10-40 | Lokulingene | Isilinganiso | Iyavutha | Ukuguga, ukuphepha komlilo okungekuhle |
| Uvolo Wengilazi | 10-80 | omuhle | omuhle | Okungashi | Izinkinga ezinzima, zothuli, ubunzima bokufaka |
| Igwebu le-XLPE | 25-80 | Kubi | omuhle | Amabanga avuthayo/FR ayatholakala | Ukumunca kahle komsindo |
| I-PET Fiber (Emnyama) | 15-50 | Lokulingene | Isilinganiso | Iyavutha (idinga ukwelashwa kwe-FR) | Ukuqina okulinganiselwe, ukuphepha komlilo okuphansi |
📌 Isiphetho:
- I-PU Foam ne-PET fiber zibiza kancane kodwa azanele izidingo zesimanje zokuphepha nokuhlala isikhathi eside.
- Uboya bengilazi busebenza kahle ngokuzwakalayo nangokushisa kodwa bungeza isisindo esiningi.
- I-SINOYQX 4kg/m³ igwebu le-melamine ihlanganisa ngokuhlukile ukuminyana kokukhanya okukhulu, ukumuncwa komsindo we-wideband, ukuhanjiswa kwe-thermal okuphansi, nokumelana nelangabi kwangaphakathi-ukwenza kube ukukhetha okulingana kakhulu kwezokuthutha ngololiwe.
- Izindawo Zokufaka Isicelo Ku-Rail Transit
- Izindonga zeCarbody & Ceilings
- Yehlisa isondo lesitimela nomsindo we-aerodynamic 5–8 dB(A).
- Ithuthukisa ukusebenza kahle kwe-HVAC ngokwehlisa ukudluliswa kokushisa, ukunqamula ukusetshenziswa kwamandla I-5-10%.
- I-Driver's Cab Ukunciphisa Umsindo
- Ifakwa ezindongeni, phansi, kanye nosilingi panel.
- Yehlisa umsindo we-interior cab by 6–10 dB(A), ngcono ukuphepha kanye nokunciphisa ukukhathala.
- I-Underframe & Power Compartments
- Ibanga lokusebenza: -200 ° C kuya ku-240 ° C.
- I-UL94 V-0 ukumelana nelangabi, ihambisana nayo EN 45545-2 HL3 amazinga.
- Inikeza okukabili ukuvikelwa komlilo + umgoqo oshisayo okokusebenza okubucayi.
- Izihlalo Nezingxenye Zangaphakathi
- Ifaka esikhundleni segwebu le-PU lendabuko 20-30% ukunciphisa isisindo.
- Akukho kukhishwa kwentuthu enobuthi ngesikhathi somlilo, okuqinisekisa ukuphepha kwabagibeli.
- Amathrendi embonini kanye ne-Future Outlook
- Imithetho Eqinile → Izindinganiso zomhlaba wonke (EN 45545, CRCC, NFPA 130) ziya ngokuya ziba namandla.
- I-Material Evolution → Imicu ye-PU ne-PET iyaqedwa ezinhlelweni zokusebenza.
- Ukuthuthukiswa Kwesikhathi Esizayo:
- Inhlanganisela ye-Aluminium-laminated yokuvikela okushisayo okungeziwe.
- Inhlanganisela ye-nonwoven ye-hybrid acoustic-structural solutions.
- Ukuhambisana nezitifiketi ze-RoHS/REACH ezimakethe zezemvelo zomhlaba wonke.
I-foam ye-melamine ye-SINOYQX ayiyona nje into yokufaka esikhundleni sayo—iyisisombululo esishintsha umdlalo esisunduzela ukuthutha kwesitimela ezinhlelweni eziphephile, ezilula, nezisebenzisa amandla amaningi.
