core zoo ntawm PIR Ua Npuas Ncauj HVAC Ductwork

PIR (polyisocyanurate) ua npuas dej ua npuas dej yog ib qho kev daws teeb meem ntawm cov kab hluav taws xob ua ntej uas tau txais kev nrov nrov hauv kev lag luam, kev lag luam, thiab siab -kawg HVAC thaj chaw nyob hauv xyoo tas los no.

Qhov tseem ceeb tshaj plaws ntawm PIR cov ntaub ntawv yog lawv cov thermal conductivity tsawg heev. Raws li cov ntaub ntawv thib peb -cov ntaub ntawv ntsuam xyuas, cov thermal conductivity ntawm cov khoom no ntawm 10℃tuaj yeem qis li 0.02 W/m·K, thiab txawm nyob rau hauv qis - qhov kub thiab txias (-20 degree), nws tuaj yeem ncav cuag 0.020 W/m·K. Piv nrog rau cov iav ntaub plaub (kwv yees li 0.035-0.040 W / m·K) los yog pob zeb ntaub plaub, cov rwb thaiv tsev ntawm PIR tau txhim kho los ntawm 30% mus rau 40%.

Qhov no txhais tau hais tias nrog tib lub thickness ntawm cov kav dej, PIR ducts tuaj yeem txo lub zog poob ntawm huab cua txias thiab kub thaum lub sijhawm thauj mus los. Rau ntev -lub sij hawm ua hauj lwm hauv nruab nrab cua txias tshuab, qhov thermal conductivity tsawg no tuaj yeem txhais ncaj qha rau hauv kev txuag hluav taws xob tseem ceeb. Feem ntau, nws tuaj yeem txo qhov poob ntawm lub tshuab cua txias los ntawm ntau dua 20%, nrog rau lub sijhawm them rov qab luv dua.

Kev Nyab Xeeb Hluav Taws Xob ntawm PIR Ua Npuas Ncauj HVAC Ductwork

Kev nyab xeeb yog thawj kab liab rau kev xaiv HVAC cov ntaub ntawv. PIR ua npuas ncauj yog cov khoom siv thermosetting, thiab nws cov qauv molecular txiav txim siab tias nws yuav tsis yaj thiab poob thaum raug hluav taws, tab sis hloov sai sai ua cov txheej txheem carbonized. Cov txheej txheem txheej no tuaj yeem tiv thaiv kev sib kis ntawm cov nplaim taws.

Thaum lub sij hawm sim tiag tiag, PIR duct panels feem ntau ua tau raws li BS 476 Chav Kawm 0 lossis EU EN 13501-1 B-s1,d0 tus qauv. Lawv cov pa ntsuas feem ntau yog siab dua 33%, yog nyob rau hauv qeb ntawm cov ntaub ntawv tsis-flammable.

Nyob rau hauv sib piv, tsoos polyurethane (PU) ua npuas ncauj yog ntau yooj yim rau decomposition ntawm kub kub. Kev tiv thaiv hluav taws ntawm PIR yog qhov zoo dua li ntawm PU, muab kev ruaj ntseg tiv thaiv hluav taws ntau dua rau cov chaw muaj neeg coob xws li tsev kho mob, tsev kawm ntawv, thiab khw muag khoom.

Lub zog muaj zog thiab lub teeb ntawm PIR Ua Npuas Ncauj HVAC Ductwork

PIR duct vaj huam sib luag muaj lub zog compressive siab heev. Cov ntaub ntawv qhia tau hais tias nws lub zog compressive tuaj yeem ncav cuag tshaj 202 KPa thaum deformed los ntawm 10%. Qhov no qhia tau hais tias cov ducts tiav lawm muaj kev tiv thaiv zoo heev rau compression thiab dabtsi yog khoov, thiab tuaj yeem tiv taus cua loj yam tsis muaj deformation, ua rau lawv haum rau siab - cua tshuab cua ceev nrog cua ceev txog 13-20 m / s.

At the same time, its surface density is extremely low, with a weight typically ranging from 1.3 to 1.4 kilograms per square meter, which is only one-sixth of that of traditional galvanized iron sheet ducts (approximately 8.3 kg/m²). Qhov no lub teeb yuag thiab siab - tus yam ntxwv muaj zog ua rau txo cov load- bearing lub nra ntawm lub tsev.

Tsis tas li ntawd, vim nws cov khoom ua ntej- rwb thaiv tsev, cov txheej txheem ib txwm ua ntawm cov ntaub qhwv rwb thaiv tsev paj rwb thiab ya raws- pov thawj cov khaubncaws sab nraud povtseg nyob ib ncig ntawm cov ducts raug tshem tawm, uas ua rau kev txhim kho kev ua haujlwm tau nce ntau dua 40% thiab txuag hauv qab nthab.

Environmental Attributes and Life Cycle of PIR Foam HVAC Ductwork

Los ntawm ib puag ncig kev xav, cov txheej txheem PIR niaj hnub no tsis muaj CFC (chlorofluorocarbons) thiab HCFC (hydrochlorofluorocarbons), thiab tsis muaj kev cuam tshuam rau cov txheej txheem ozone. Cov khoom tseem ua raws li RoHS ib puag ncig cov lus qhia. Qhov tseem ceeb tshaj, qhov ntev - rwb thaiv tsev kev ua tau zoo txhais tau hais tias cov pa roj carbon emissions ntawm lub kaw lus tau txo qis hauv nws lub neej voj voog.

Txawm hais tias tus nqi pib ntawm PIR ducts yog siab dua me ntsis ntawm cov khoom siv hluav taws xob tsawg- kawg, nws muaj cov nqi kho mob qis heev, xoom condensation ua rau cov nqi kho qab nthab, thiab kev txuag hluav taws xob tseem ceeb.

Lub neej voj voog tus nqi (LCC) feem ntau yog ntau dua 30% qis dua li cov kab ke ib txwm siv. Nws lub neej kev pabcuam tsim tuaj yeem ncav cuag 20 txog 22 xyoo yam tsis tas yuav hloov cov txheej rwb thaiv tsev.
