Lub teeb PU Pre-insulated Duct

Lub teeb PU (Polyurethane) Pre-insulated Duct yog lwm txoj hauv kev niaj hnub rau cov khoom siv hlau ua haujlwm rau cua sov, qhov cua, thiab cua txias (HVAC) systems . Nws yog ib lub vaj huam sib luag sib xyaw ua ke uas ua ke nrog thermal rwb thaiv tsev thiab huab cua- xa cov haujlwm hauv ib yam khoom.

Nws yog dab tsi?

Lub duct yog tsim los ua ib qho nyuaj "sandwich" vaj huam sib luag:

Core Khoom:Ib qho tawv polyurethane (PU) ua npuas ncauj, uas muab thermal rwb thaiv tsev zoo heev. Qee qhov kev hloov pauv siv PIR (polyisocyanurate) rau kev txhim kho hluav taws kub.

Facing Khoom:Ob sab ntawm cov tub ntxhais ua npuas ncauj feem ntau yog laminated nrog ib txheej aluminium ntawv ci. Rau cov ntawv thov sab nraud lossis xav tau ntau dua, lub ntsej muag tuaj yeem yog cov ntawv txhuas tuab dua lossis ua ntej -painted galvanized steel. Rau qhov chaw huv huv, feem ntau siv cov ntawv txhuas du.

Cov txiaj ntsig tseem ceeb ntawm Kev Nyuaj Siab PU Pre- insulated Duct Over Traditional Hlau Ducts

Lub teeb PU ducts muaj ntau yam kev ua tau zoo thiab kev ua tau zoo:

Qhov tseem ceeb Lighter:

Ntsuas txog1.3-1.4 kg / m², lawv muaj zog dua li cov galvanized steel ducts (nyob ib ncig ntawm 8.3 kg / m²), uas txo cov qauv ntawm lub tsev thiab ua kom yooj yim tuav.

Faster thiab yooj yim installation:

Lawv xav tau ib qho - cov txheej txheem kev teeb tsa, tshem tawm qhov xav tau ntxiv cov rwb thaiv tsev cais thiab vapor barriers tom qab.

Qhov zoo tshaj plaws thermal rwb thaiv tsev:

Lub polyurethane ua npuas ncauj core muaj ib tug tsawg thermal conductivity ntawm kwv yees li0.02 W/m·K, uas minimizes zog poob thiab tiv thaiv condensation.

Qhov chaw -Txuag:

Lub kaw lus yog compact, txo lub qab nthab qhov chaw xav tau rau ductwork.

Lub neej ua haujlwm ntev:

PU ducts tau tshaj tawm tias muaj lub neej ua haujlwm ntawmntau tshaj 20 xyoo, piv rau 6-7 xyoo rau cov tsoos galvanized hlau ducts.

Cov txheej txheem Fabrication ntawm lub teeb yuag PU Pre- insulated Duct

Kauj ruam 1 – Tracing
Qhia txog qhov xav tau cov duab kos ncaj qha rau ntawm lub vaj huam sib luag nto raws li cov duab kos duab.

Kauj Ruam 2 - Txiav
Siv cov cuab yeej txiav phau ntawv, txiav cov npoo ntawm lub vaj huam sib luag thiab txiav 90℃"V"-zoo li tus grooves rau hauv lub vaj huam sib luag uas yuav tsum tau khoov.

Kauj Ruam 3 – Gluing
Siv ib txheej txheej ntawm cov nplaum rau qhov npaj txiav ntawm cov panels.

Kauj Ruam 4 – Folding
Thaum cov nplaum tau kho tag nrho, quav cov grooved sab panels rau ib leeg los tsim cov kab ncaj nraim.

Kauj Ruam 5 – Taping
Siv daim kab xev sib khi nkaus xwb rau sab nraud longitudinal seams qhov twg cov npoo vaj huam sib luag sib ntsib, kom ntseeg tau tias huab cua- nruj.

Kauj Ruam 6 - Flanging
Tom qab siv cov nplaum thiab muab tso rau ntawm lub kaum sab xis steel, txhim kho PVC lossis txhuas tsis pom flanges ntawm cov kav dej xaus.

Kauj Ruam 7 – Txhim kho
Yog tias xav tau, ntxiv dag zog rau cov kav dej siv cov khoom siv aluminium thiab GI (galvanized hlau) zoo li cov disks ntxiv rau kev ruaj ntseg.

Kauj Ruam 8 – Sealing
Tom qab cov kav dej tau sib sau ua ke, hermetically kaw tag nrho cov pob qij txha sab hauv thiab cov ces kaum nrog silicone sealant kom lav tag nrho huab cua- nruj.
