pu rwb thaiv tsev board Rigid ua npuas ncauj polyurethane board muaj tsawg thermal conductivity thiab zoo thermal yam ntxwv. Thaum ib daim ntawm polyurethane siv rau 35 ~ 4 0kg / m3, thermal conductivity tsuas yog.018 ~ 0.024w / (mk), li ntawm ib nrab ntawm EPS, yog qhov tsawg tshaj plaws thermal conductivity ntawm txhua feem ntawm lub txheej txheem.
pu rwb thaiv tsev board txhav ua npuas ncauj polyurethane board nyob rau hauv kev sib kis ntawm kev nyiag, thiaj li yuav tiv thaiv cov yam ntxwv. Ib daim ntawm polyurethane nyob rau hauv pem hauv ntej ntawm 90 feem pua, yog hydrophobic nyem, tsis yooj yim rau nce thermal conductivity vim noo noo nqus, sab nrauv phab ntsa tsis yooj yim rau dej.
pu rwb thaiv tsev board txhav ua npuas ncauj polyurethane board tshav kub rwb thaiv tsev, yooj yim, muaj kuj. Tom qab polyurethane koom nrog hauv kev yooj yim, nws yog ib lub thawv ntawm cov nplaim hluav taws kub nyhiab. Nws cov ntsiab lus nqa tuaj yeem mus rau pem hauv ntej ntawm Celsius degree, tsuas yog thaum cov av noo siab heev, cov txheeb cais tau tsim tawm: ntxiv rau, polyurethane hauv kev ua haujlwm ntawm nws cov cuab yeej hauv paus ntsiab lus los tsim cov pa roj carbon deposits, uas yuav pab tiv thaiv cov tom ntej. ntaus ntawv. Muaj peev xwm tiv thaiv tau los ntawm nplaim taws qub txeeg qub teg. Tsis tas li ntawd, polyurethane nyob rau hauv kev lag luam kuj tsis ua rau tsis muaj txiaj ntsig siab.
Yuav tsis zoo tib yam polyurethane xim nyob rau hauv zoo combustion tshav kub rwb thaiv tsev tiv thaiv hluav taws waterproof thiab fireproof cais los tiv thaiv tshav kub rwb thaiv tsev yam ntxwv, nyob rau hauv tib yam los ua tus tsis zoo tshwm sim, yuav ua rau kev soj ntsuam ntawm lub tsev lub hnab ntawv kwv yees, kuj nce nyob rau hauv lub tsev siv cheeb tsam.
pu rwb thaiv tsev board txhav ua npuas ncauj polyurethane board tiv thaiv qhov poob ntawm kev ua haujlwm zoo nkauj, nplaum alkali tsis kam, ua tiav ruaj khov, nyab xeeb.
Lub porosity ntawm pu rwb thaiv tsev board txhav ua npuas ncauj polyurethane board yog ruaj khov, feem ntau hais lus, nws yog tsim los ntawm kaw qhov pores, thiab nws muaj cov yam ntxwv muaj pes tsawg leeg, thiab ntxiv rau, nws muaj khov thiab thawing kuj thiab suab haum. Rigid ua npuas ncauj polyurethane yog tsim los ntawm cov iav tsim nyog, uas tuaj yeem siv thiab ua haujlwm hauv ntau yam kev mob. Nws raug pom zoo tias nyob rau hauv cov xwm txheej ntawm kev siv thoob plaws hauv lub khob theem ntawm cov muaj pes tsawg leeg, nws tsis yooj yim rau muab kev puas tsuaj rau hauv qhuav heev, dej ziab los yog electrochemical corrosion, thiab thawj qhov kev xaiv ntawm cov kab zoo tshaj plaws ntawm cov kab, fungi lossis algae. yuav txawv ntawm kev puas tsuaj ntawm cov nas thiab lwm yam ua rau sab nraud.
pu rwb thaiv tsev board txhav ua npuas ncauj polyurethane board feem ntau raug nqi. Txawm hais tias cov nyiaj hli ntawm ib chav tsev polyurethane yog siab dua li ntawm ib lub phaj nyem, qhov kev txhim kho desulfurization tsis yog offset los ntawm ib tug loj degree ntawm kev tsom xam ntawm cua sov thiab txias desulfurization.
