PIR Ua Npuas Ua Si Cov Khoom Siv Khoom Siv

1. Tshuaj lom neeg sib xyaw

Main raw materials: isocyanate and polyether. Forms a highly cross-linked structure with isocyanurate rings via foaming, with closed-cell rate >90%. Nta: du nto, cov txheej txheem yooj yim, lub teeb yuag, roj & tshuaj lom neeg tsis kam.

2. Lub zog lub cev

Kub kuj: 80℃(ib txwm); -100℃(txheej loj);

Thermal conductivity: tsawg li 0.02-0.022 w / (map k), rwb thaiv tsev zoo dua thaum muaj kub tsawg;

Mechanical zog: Compressive lub zog ntau dua los yog sib luag rau 200kpa, flexural zog ntau dua lossis sib npaug rau hauv pem teb cua sov, ru tsev thauj khoom- cov kabmob txheej);

Kev Ntsuas Hluav Taws: Bs 476 Tshooj 6 & 7 class0 Astm E-84Class a

3. Lub Neej

Muaj zog kev laus; Cov dej noo permeability coefficiess tsawg dua los yog sib xyaw ua ke rau 3.34 NG (PACHN%, ua kom ntev}}}}}}}}} moist moist moist moistုင်း noo thiab ruaj khov.

Cov tub ntxhais zoo ntawm cov laug cam ua npuas dej hauv HVAC cov ntawv thov

Kev tawg hauv qhov ntsuas cua sov

Nrog ib qho ultra - tsis muaj thermal bondality ntawm 0.021 W / (MEX K), nws muaj zog ntau dua 250% ntau dua hluav taws xob piv rau cov khoom siv polyurethane. Nws cov raug kaw - cell cell tus nqi tshaj li 90% muaj txiaj ntsig zoo rau kev txhawb nqa dej txias thiab 10℃qes {} kub} kub tshuab cua twj khoom.

Txawj tej kev nyab xeeb hauv hluav taws

Leveraging tus ntoo khaub lig heev-} Linked qauv ntawm Polyisocyanurate Rings, nws muaj cov oxygen qhia ntau dua lossis sib npaug ntawm GB8624 b1-chav kawm b1-chav kawm. Thaum huab cua ducts dhau los ntawm cov tshuab hluav taws kub, nws tuaj yeem ncua hluav taws kis rau 45 feeb, txwv 20 feeb cov ntaub ntawv ntawm cov polyurethane cov ntaub ntawv.

Kev hloov kho tau nyob hauv kev ua haujlwm zoo

Txheem Quav Huab Cua Caj Dev Ciaj (50-55kg / mp) ncav cuag lub zog compressive ntawm 220kpa, muaj peev xwm nrog nrog kev kub ntxhov siab ntawm 30m / s cua ceev. Txhuas Ntawv Ci Composite qauv ib txhij muab cov dej noo tsis kam (dej nqus tus nqi <0.5%) thiab corrosion tsis kam.

Cov teeb meem ntau

Yuav ua li cas cov rwbululation kev ua tau zoo ntawm PU ua ntej -} insulated duct piv rau cov ducts tsoos?

PU ua npuas ncauj muaj tsawg kawg thermal conductivity (nyob ib ncig ntawm 0.020 w / min k), kom zoo dua li cov khoom lag luam yeeb yaj kiab galvanized zoo li cov khaubncaws sab nraud. Qhov no txhais tau Pu Pre - insulated ductions txo cov cua sov txo / txhim kho hluav taws xob txuag thiab txo qis HVAC kev ua haujlwm.

Ntev npaum li cas kev pabcuam lub neej ntawm pu ua ntej - italulated huab cua ciav dej?

Nrog rau kev tsim kom tsim nyog, kev txij nkawm, thiab tiv thaiv kev mob hnyav, pu pre - istulated ducts tuaj yeem kawg20+ xyooCov. Lawv cov kev ruaj khov yog nyob ntawm qhov zoo li cov av noo ib puag ncig, raug tshuaj lom neeg, thiab kev txhawb nqa qauv.

Puas yog pu ua ntej - edulated duucts lub teeb yuag? Qhov no cuam tshuam rau kev teeb tsa li cas?

Yog lawm, lawv tau cuam tshuam ntau dua li cov roj av galvanized yas (kom txog 72% sib zog). Qhov no txo cov kev thauj khoom ntawm cov tuam tsev (tseem ceeb rau lub qab nthab lossis ua kom yooj yim {2} Tsis muaj kev txhim kho cov khoom siv hnyav, ua kom lub sijhawm tsim muaj zog.

Yuav Pu Pre - awulated duct tau customized rau cov haujlwm xav tau tshwj xeeb?

Kiag li. Cov neeg tsim khoom lag luam muaj kev sib cav ntawmVAJ HUAM SIB TAS TASLIC(piv txwv li, 20mm rau 50mm, raws li kev ua rwb thaiv tsev),qhov loj(Ntev, Dav), thiabFam cov ntaub ntawv(piv txwv li, qib sib txawv ntawm txhuas rau corrosion tsis kam).
