Insulated saj zawg zog Aluminium cua duct yog tsim los ntawm lub raj sab hauv, rwb thaiv tsev thiab lub tsho.
1.Inner tube: yog ua los ntawm ib daim ntawv ci los yog ob, uas yog spirally mob nyob ib ncig ntawm siab elastic steel hlau; Cov ntawv ci tuaj yeem yog laminated Aluminium ntawv ci, aluminised PET zaj duab xis lossis PET zaj duab xis.
Thickness ntawm laminated Aluminium ntawv ci: 0.023mm (ib sab), 0.035mm (dual side).
Thickness ntawm Aluminized PET zaj duab xis: 0.016mm.
PET zaj duab xis Thickness: 0.012mm.
Txoj kab uas hla ntawm Bead hlau: 0.96mm, 0.12mm.
Pitch ntawm lub helix: 25mm, 36mm.
2.Rwb thaiv tsev: feem ntau nrog centrifugal iav ntaub plaub
Thickness: 25mm, 50mm.
Ceev: 16kg / m³, 20kg / m³, 24kg / m³.
3.Jacket: longitudinal seam tsho thiab ncig seam tsho
3.1.Longitudinal seam tsho: Nws yog ua los ntawm ib qho ntawm cov ntaub ntawv voj voog mus rau hauv ib lub cylindrical zoo nrog ib tug longitudinal seam. Cov qauv no yog ib qho yooj yim rau tawg thaum lub tshuab cua compressed los yog khoov.
3.2.Circular seam tsho yog ua los ntawm ib daim ntawv ci los yog ob, uas yog spirally mob nrog iav fiber nyob rau hauv nruab nrab, thiab cov ntawv ci yuav laminated Aluminium ntawv ci, aluminised PET zaj duab xis los yog PET zaj duab xis. Cov qauv overcomes qhov shortcoming ntawm longitudinal seam tsho --- cracking yooj yim thaum lub duct yog compressed los yog khoov. Cov iav fiber reinforced lub tsho.
Muaj peb txoj hauv kev ntawm iav fiber reinforcing lub tsho:
① Ncaj iav fiber reinforcement: Nrog ib los yog ob peb ncaj iav fiber ntau nyob nruab nrab ntawm ob txheej ntawm zaj duab xis.(Daim duab 1).
② π puab iav fiber reinforcement: Nrog π puab iav fiber mesh band nyob nruab nrab ntawm ob txheej ntawm zaj duab xis. (Daim duab 2)
③ # cov iav fiber ntau reinforcement: Nrog ib los yog ob peb ncaj iav fiber spirally mob ua ke nyob rau hauv nruab nrab ntawm ob txheej ntawm films; thiab nrog ob peb iav fiber ntau muab tso rau hauv nruab nrab ntawm cov yeeb yaj duab nyob rau hauv longitudinal kev taw qhia; uas daim ntawv # zoo nyob rau hauv lub tsho nrog cov spirally mob iav fiber. (Daim duab 3)
Qhov ncaj iav fiber reinforcement txhim kho lub zog warp ntawm lub tsho thiab tuaj yeem tiv thaiv lub tsho los ntawm tearing nyob rau hauv txoj kab ntev. Thiab lub π puab iav fiber reinforcement muaj qhov zoo dua los tiv thaiv kev ua haujlwm zoo dua li qhov ncaj. Txawm li cas los xij, # duab iav fiber reinforcement sib xyaw ua ke qhov zoo ntawm ob lub qub. # cov duab yog qhov zoo tshaj plaws nyob rau hauv tag nrho peb txoj kev txhawb nqa.
