Cov lus nug ntawmPolyurethane ua npuas ncauj duct vaj huam sib luag
Puas yog PIR ua ntej - istulated (pi) ducts xav tau cov rwb thaiv tsev ntxiv tom qab kev teeb tsa?
Tsis muaj. Li qub hlau ductions (uas yuav tsum tau cais cov khaubncaws sab nraud povtseg (uas xav tau cais cov khaubncaws sab nraud povtseg zoo li fiberglass), PIR ua ntej - insulated nrog ntsib kev ntsib kev sib xyaw. Qhov kev xav tau no tshem tawm qhov xav tau ntawm kev ua haujlwm ntawm sab nraud ua haujlwm, txuag sijhawm thiab ua haujlwm.
Nyob rau hauv twg cov xwm txheej yog PIR ua ntej -} insulated duct?
Nws yog dav siv nyob rau hauv cov tsev lag luam xws li chaw haujlwm, chaw khaws khoom, thiab chaw ntiav, chaw kho mob thiab khoom noj txias thiab txias thiab txias thiab txias tshuab.
PIR li cas pre {- aw one a roulated duct sup ntawv ntim?
-Nws ib txwm ntim hauv cov yeeb yaj kiab yas lossis thawv, nrog 10 nplooj ntawv ib pob.
Yuav ua li cas tswj pir ua ntej - istulated (pi) ducts?
Kev tu yog tsawg heev. Kev kuaj xyuas ib txwm rauKoom Tes Tiav(txhawm rau tiv thaiv cua toughage) thiabNto puas(piv txwv li, punctures nyob rau hauv txhuas ntsib) yog pom zoo. Ntxuav sab hauv lub sijhawm tsis tu ncua (nrog cov tshuaj ntxuav me me) pab kom muaj airflow efficiency, tshwj xeeb tshaj yog nyob rau hauv kev nyiam huv {{}}}}}}}}}}}}} cov chaw rhiab.

Kev Kub Cua Zoo Txuag Los Tive Project
PIR foam nta ib tug finer kaw - ntawm tes qauv thiab muaj qhov qis tshaj plaws thermal conductivity, ib qho ntawm cov khoom hauv rwb thaiv tsev. Qhov no txhais tau hais tias nws tuaj yeem tiv thaiv cov huab cua txias / huab cua txias hauv raj xa hluav taws xob nrog tshav kub sab nraud.
Kev Nyab Xeeb Zoo
PIR cov khoom muaj cov nplaim hluav taws xob rov qab. Thaum raug hluav taws, nws cov nplaim yuav nrawm nrawm carbonize thiab ua cov txheej tiv thaiv tuab tuab ntawm Coke. Qhov txheej txheem tiv thaiv no yuav ua kom tiv thaiv tau zoo ntxiv rau kev nkag mus ntxiv thiab sib kis cov nplaim taws, thiab muaj cov pa hluav taws xob tsawg.
Zoo heev noo noo - pov thawj thiab dej vapor nkag mus tsis kam
Lub kaw {- tus nqi cell ntawm PIR yog qhov nyuaj tshaj plaws (saib kom muaj kev phom sij rau 95%), uas txhais tau tias cov kev ua haujlwm rwb thaiv tsev tsis cuam tshuam vim noo noo. Qhov no yog qhov tshwj xeeb tshaj yog nyob hauv ib puag ncig noo.
Cov qauv thiab muaj pes tsawg leeg ntawm polyurethane ua npuas ncauj duct vaj huam sib luag
Cov Khoom Siv Tseem Ceeb:Rigid Polyurethane (PU) Ua Npuas Ncauj nrog lub kaw lus kaw cia, muab cov khoom siv hluav taws xob qis (0.018-0.025 w / min k). Nrog 50 kg / m³ ua ib qho rau cov ntawv thov cluct.
Cov khaubncaws sab nraud pov saum npoo:Txhawb nqa nrog txhuas ntawv ci (60-80 microns) ntawm ob sab, muab kev tiv thaiv corrosion, thiab huab cua zoo rau cov cua tsis muaj zog.
Tsim kev sib xyaw:Hoobkas -} Studened raws li pre- insulated panels, tshem tawm cov kev xav tau ntawm- Cov chaw ua haujlwm ruaj khov.
Cov Khoom Siv Tseem Ceeb Ntawm Polyurethane Ua Npuas Ncauj Ciav Caj Teb
Thermal efficiency:Qhov qis tshaj thermal conductivity nyob rau cov khoom duct, ua kom cov rwb thaiv tsev thinner (piv txwv li, 20-40 mm) piv rau iav ntaub plaub lossis phenolic ua npuas ncauj. Qhov no txo lub zog poob los txog li 50% piv rau cov tsoos galvanized steel ductions.
Kev hnyav:Nyhav 72% tsawg dua galvanized steel, ua rau nws zoo tshaj plaws rau retrofitting txoj haujlwm nrog cov teeb meem ntim kev txwv.
Cua nruj nreem:Hoobkas - Daim pob qij txha thiab cov chaw du uas txo cov dej xau, txhim kho kev ua haujlwm zoo thiab txo cov kiv cua kev siv hluav taws xob.
Qhov ruaj khov:UV {- tiv taus txhuas ntawv ci thiab kaw {} Cell Ua Npuas Ncauj muaj lub neej 20 xyoo, txawm tias muaj ib puag ncig huab cua.
Tu nkauj:Tsis tau txhuas chaw inhibit cov kab mob kev loj hlob, cov qauv sib ntsib rau kev ua zaub mov noj, cov chaw muag tshuaj, thiab tsev kho mob.
Cim npe nrov: Polyurethane ua npuas ncauj duct pawg vaj huam sib luag, Tuam Tshoj, cov chaw muag khoom, chaw tsim khoom, Hoobkas, Mekas
