PU Sandwich Panel yopangidwa ndi makina

1.Polyurethane sangweji gulu ali otsika matenthedwe conductivity ndi ntchito bwino kutentha.Pamene kachulukidwe wa polyurethane okhwima ndi 35 ~ 40kg/m3, matenthedwe madutsidwe ndi 0.018 ~ 0.024w/(mk), amene ali pafupifupi theka la EPS, ndipo ndi otsikitsitsa pakati pa zipangizo zonse kutchinjiriza matenthedwe.

2.Polyurethane ili ndi mphamvu zowonongeka ndi madzi.Maselo otsekedwa a polyurethane okhwima ali pamwamba pa 90%, omwe ndi zinthu za hydrophobic ndipo sangawonjezere kutentha kwa matenthedwe chifukwa cha kuyamwa kwa chinyezi, ndipo pamwamba pa khoma silingalowe madzi.

3.Polyurethane ndi moto, moto woyaka komanso wosagwirizana ndi kutentha kwakukulu.Pambuyo powonjezera choletsa moto, polyurethane ndi chinthu chozimitsa moto chozimitsa moto.Kufewetsa kwake kumatha kufika madigiri 250 Celsius, ndipo kumangowola pa kutentha kwakukulu: kuwonjezera apo, polyurethane imapanga ma depositi a kaboni pamphumi yake ikayaka.Mbali imeneyi ya kaboni madipoziti kumathandiza kuti thovu lili m'munsimu.Zingathe kuteteza kufalikira kwa malawi.Komanso, polyurethane sipanga mpweya woipa pa kutentha kwambiri.

4.Chifukwa cha kutsekemera kwabwino kwa kutentha kwa bolodi la polyurethane, pansi pa zofunikira zomwe zimatenthetsa kutentha, makulidwe a envelopu yakunja ya nyumbayo akhoza kuchepetsedwa, motero kuwonjezera malo ogwiritsira ntchito m'nyumba.
5.Strong anti-deformation kuthekera, kosavuta kusweka, kukhazikika komanso kotetezeka kumaliza.

6.Mpangidwe wa porosity wa zinthu za polyurethane ndizokhazikika, ndipo kwenikweni zimakhala zotsekedwa-maselo.Sikuti imangokhala ndi magwiridwe antchito abwino kwambiri oteteza kutentha, komanso imakhala ndi kukana bwino kwa kuzizira komanso kuyamwa kwamawu.Wapakati moyo wa olimba thovu polyurethane kutchinjiriza kapangidwe akhoza kufika zaka zoposa 30 pansi ntchito wamba ndi kukonza zinthu.Zitha kutheka m'moyo wa kapangidwe kameneka kagwiritsidwe ntchito bwino, kowuma, konyowa kapena kuwonongeka kwa electrochemical, komanso chifukwa cha kukula kwa tizilombo, bowa kapena algae kapena chifukwa cha kuwonongeka kwa makoswe ndi zinthu zina zakunja, sizingachitike. kuonongeka.

7.Comprehensive mtengo.Ngakhale mtengo wamtundu wa thovu la polyurethane ndi wokwera kuposa wa zida zina zotchinjiriza zachikhalidwe, mtengo wokwerawo udzachepetsedwa ndi kutsika kwakukulu kwamitengo yotenthetsera ndi kuziziritsa.
