I. Qhov zoo dua ib txwm muaj huab cua
| chaw ua uas tsis tau haus | PIR foam ducts | Galvanized hlau duct | Ducolle cua |
| thermal conductivity | 0.018-0.022 W/(m ·K) | Tsis muaj rwb thaiv tsev | 0.036 W/(m ·K) |
| Kev Ntsuas Hluav Taws | Qib B1 (Core) + Qib A1 (Txheej Txheej) | Yuav tsum muaj hluav taws xob ntxiv | Chav Kawm B1 (tab sis muaj cov pa luam yeeb siab tiag tiag) |
| qho hnyav | 1.4-4.5 kg / m² | 15-20 kg / m² | 8-10 kg / m² |
| Kev ua hauj lwm nruab | 3-6 zaug ntau dua li cov huab cua | On - chaw ntawm Rwb thaiv tsev + Hluav Taws Xob Tiv Thaiv Hluav Taws Xob | Tus brittleness yog loj thiab poob poob yog siab |
| Kev Pabcuam Lub Neej | Ntau tshaj 20 xyoo | 5-8 xyoos (yooj yim rau xeb) | 3-5 xyoos (hmoov yooj yim) |
Ii. Xaiv Kev Xaiv
Xaiv raws li ib puag ncig
Sab nraum zoov los yog siab - av noo ib puag ncig:Ua ntej kev siv ntawm 200 {- micron aluminium ntawv nyiaj los yog cov xim hlau phaj phaj, ua ke nrog anti-pwm tsho.
Cov Chav Huv Si:Ib Leeg - ob tog sauv aluminium ntawv ci (ra tsawg dua los yog sib npaug rau 0.8 μm) yog siv, nrog kev sib tw vuam ntawm cov nqaws.
Xaiv raws li lub kaw lus siab
Tsawg - qhov system siab (tsawg dua lossis sib npaug nrog 1000 pa):20mm tuab qauv phaj.
Nruab nrab thiab kev kub siab siab (1000-4500 PA):25 -}}}}}}} 30 fuab requestCing phaj, nrog ob-txheej aluminium ntawv nyiaj los yog galvanized steel phaj txheej.
Xaiv raws li Kev Tiv Thaiv Hluav Taws Xob
High - kev pheej hmoo ntawm thaj chaw (xws li cov ntug dej hauv av):A1 qib xim steel phaj txheej + B1 cov khoom siv tseem ceeb, ntawv pov thawj los ntawm EN 13501-1.
III. Ib puag ncig thiab kev pabcuam lub neej
A. Kev tiv thaiv ib puag ncig ua haujlwm
Fluorine - dawb (CFC / HCFC {}} free {{free, thiab pub dawb} dej foaming ua raws li EU RoHS cov lus qhia.
Rov qab siv dua: PIR ua npuas ncauj thiab cov txheej hlau npoo tuaj yeem sib cais thiab rov ua dua tshiab, txo cov khib nyiab.
B. Kev Pabcuam Lub Neej
Raws li kev siv nyiaj ib txwm muaj, lub neej pabcuam yog loj dua los yog sib npaug rau 20 xyoo, thiab cov txheej saum npoo tuaj yeem txuas ntxiv rau ntau tshaj 25 xyoos. Piv txwv li, anti - corrosion txheej rau saum npoo ntawm txhuas ntawv ci tuaj yeem tiv thaiv lub yaig nag thiab muaj roj av khib.
Cim npe nrov: PU ua npuas ncauj insulated du tshuab, Tuam Tshoj, cov chaw muag khoom, chaw tsim khoom, Hoobkas, Mekas
