PIR Caj Npauj Npas

(1) PIR ua npuas ncauj

PIR foam yog tsim los ntawm cov tshuaj tiv thaiv thiab foaming ntawm isocyanate thiab polyether raws li kev ua ntawm catalyst. Nws kaw {- tus qauv xov tooj ntawm tes muab cov khoom lag luam uas muaj cua sov tsis muaj zog Nyob rau tib lub sijhawm, cov khoom siv no muaj lub zog siab thiab ruaj khov, tuaj yeem tiv thaiv ib qho kev ntsuas siab thiab sab nraud, thiab tsis yooj yim rau deform. Hais txog kev kub kub tiv thaiv, pir ua npuas ncauj muaj qhov tseem ceeb: thaum hlawv txheej tau tsim nyob rau saum npoo los thaiv kev sib kis. Cov khoom lag luam feem ntau tuaj yeem ncav cuag cov nplaim hluav taws - retardant B1 qib.

 

(2) cov ntaub ntawv qhia

Aluminium ntawv ci ntsib: feem ntau hom, nrog thicknesses zoo li 60 - 80μm. Embossed Aluminium Ntawv Nyiaj Boosts Board lub zog thiab tsos. Nws muaj cov dej noo zoo heev thiab kev tiv thaiv corrosion, tiv thaiv noo noo - induced txo nyob rau hauv pir foam lub rwb thaiv tsev lossis kev loj hlob pwm. Tsis tas li, nws txoj kev du loj txiav cov cua ntws tsis kam, txhim kho duct cua txias.

Vim li cas nws ua haujlwm zoo dua

1. Cov huab cua zoo ib yam, tus nqi qis dua

Lub PU Ua Npuas Ncauj Cov Txawj Ntse ntawm Rwb Thaiv Tsev Thaum tshav kub kub Qhov no txo ​​hvac haujlwm los ntawm 30-40%, txiav cov nqi hluav taws xob tsis tshua muaj txiaj ntsig rau cov tuam tsev ntau.

2. Lub teeb yuag & yooj yim rau nruab

Far sib dua dua hlau ducts, cov no yog ib qho yooj yim rau maneuver. Pre ...- Txiav rau cov qauv ntau thiab tsawg, lawv tuaj yeem raug tshem tawm sai sai nrog cov cuab yeej yooj yim. Tsis muaj ib qho kev tiv thaiv ntxiv xav tau -} sib txuas thiab mus. Lub sij hawm installation yog halved, ua kom cov nqi ua haujlwm ruaj khov.

3. Ntev rau ntev-} kev siv

Lub kaw - kev ua npuas ncauj ntawm tes ua npuas dej thiab pwm. Aluminium lossis hlau outer txheej kom tsis txhob xeb thiab dents, txawm tias muaj cov av noo lossis siab} cov chaw tsheb khiav. Nrog kev saib xyuas tsawg kawg, lawv xeem hnub kawg 15-20 xyoo tsis muaj sijhawm kho.

4. Hluav Taws Kub -} nyab xeeb tsim

Kho nrog nplaim retardants, pu npuas sooam slows kis thiab txo cov pa hluav taws kom muaj pa taws. Nws ua tau raws li cov qauv nruj (piv txwv li, gb 8624 chav B1), ua kom muaj kev nyab xeeb rau tsev, chaw haujlwm, thiab tsev kho mob.

5. Tus, huv si cua

Ib qho super -} du sab hauv minimizes cua tsis kam, txhim kho kev txuag hluav taws xob hvac thiab txo hluav taws xob. Nws kuj tseem tiv taus cov hmoov av thiab cov lag luam greatup, ua kom muaj zog cua tshuab nqus cua}}} qhov zoo tagnrho rau cov tsev kawm ntawv, thiab chav ua haujlwm.

6. Haum rau txhua qhov chaw

Yooj yim zoo li cov duab sib dhos, cov voj voog, lossis cov ntaub ntawv kev cai rau cov chaw nruj. Haum rau tsev, chaw ntiav pw, khw, thiab cov khoom siv me me- txhua qhov chaw txhim kho hluav taws xob txhim kho lossis qhov cua txias.

Polyurethane ua ntej - one} Insulated duct yog qhov yooj yim xaiv yog qhov yooj yim {{{{{{3} - purifying. Nws ua haujlwm li koj lub tsev ua.

 

(I) Cov ntsiab lus installation

Marking: Make proper marks on the PIR duct board according to design and on-site requirements.

Kev txiav: Siv cov cuab yeej tshaj lij los txiav cov txiag raug kom yog yog yog yog yog txiav cov thawj coj ua raws cov cim.

Gluing: Siv cov kua nplaum tshwj xeeb ntawm cov chaw sib koom ua ke ntawm cov laug cam.

Folding: Fold cov borged tsas rau hauv cov duab ntawm ib tug ciav.

Khawm: Siv daim kab xev rau ntawm cov nqaws kom txhim kho airtightness.

Txhim kho profiles: haum cov ntaub ntawv tshwj xeeb kom txhawb nqa tus duct.
