📌 Qetello:
- PU foam le PET fiber li theko e tlase empa ha li lekane bakeng sa litlhoko tsa sejoale-joale tsa polokeho le nako e telele.
- Boea ba khalase bo sebetsa hantle ka molumo le mocheso empa bo eketsa boima bo feteletseng.
- SINOYQX 4kg/m³ foam melamine ka tsela e ikhethang ultra-light density, wideband sound absorption, low conductivity ea thermal, le intrinsic flame resistance-e etsa khetho e leka-lekaneng bakeng sa lipalangoang tsa terene.
- Libaka tsa Kopo ho Rail Transit
- Mabota a Carbody & Ceilings
- E fokotsa lerata la mabili le lerata la aerodynamic ka 5–8 dB(A).
- E ntlafatsa katleho ea HVAC ka ho theola phetisetso ea mocheso, ho fokotsa tšebeliso ea matla ka 5-10%.
- Phokotso ea Lerata la Cab Cab
- E sebelisoa maboteng, fatše le liphanele tsa siling.
- E fokotsa lerata la ka hare ho koloi ka 6–10 dB(A), ho ntlafatsa polokeho le ho fokotsa mokhathala.
- Likarolo tse ka tlas'a liforeimi le Matla
- Sebaka sa Ts'ebetso: -200 ° C ho + 240 ° C.
- UL94 V-0 ho hanyetsa lelakabe, ho lumellana le EN 45545-2 HL3 maemo.
- E fana ka tse peli tšireletso ea mollo + mokoallo oa mocheso bakeng sa lisebelisoa tse hlokolosi.
- Litulo & Likarolo tsa ka Hare
- E nkela sebaka sa setso sa PU foam ka 20-30% ea ho fokotsa boima ba 'mele.
- Ha ho na mosi o chefo o tsoang nakong ea mollo, ho netefatsa polokeho ea bapalami.
- Mekhoa ea Indasteri le Pono ea Bokamoso
- Melao e thata → Litekanyetso tsa lefats'e (EN 45545, CRCC, NFPA 130) li ntse li eketseha ka thata.
- Phetoho ea Lintho Tse bonahalang → likhoele tsa PU le PET li ntse li felisoa lits'ebetsong tsa pele.
- Nts'etsopele ea Bokamoso:
- Aluminium-laminated composite bakeng sa tšireletso e eketsehileng ea mocheso.
- Li-composites tse sa lohang bakeng sa tharollo ea hybrid acoustic-structural.
- Ho lumellana le litifikeiti tsa RoHS/REACH bakeng sa mebaraka ea tikoloho ea lefatše.
Foam ea melamine ea SINOYQX ha se feela thepa e nkelang sebaka—ke tharollo e fetolang papali e sutumelletsang lipalangoang tsa terene ho ea lits'ebetsong tse sireletsehileng, tse bobebe le tse bolokang matla haholoanyane.
