Ubweya wamba wa miyalagulu la masangwejiIli ndi zigawo ziwiri zachitsulo zokhala ndi pakati pa ubweya wa miyala. Kapangidwe kameneka kamapatsa zinthuzi mphamvu zabwino zakuthupi komanso mphamvu zokhazikika za mankhwala. Chipinda cha masangweji cha ubweya wa miyala sichimagwiritsidwa ntchito kwambiri m'nyumba wamba, komanso chodziwika kwambiri pomanga malo osungiramo zinthu ozizira.
Zabwino kutentha kutchinjiriza ntchito ya bolodi yozizira yosungirako ubweya wa thanthwe
Ma panelo a masangweji a ubweya wa thanthweZitha kukhala zinthu zomangira zomwe zimagwiritsidwa ntchito posungira zinthu zozizira, chifukwa cha mphamvu zawo zabwino zotetezera kutentha.
Chida chachikulu cha sandwich panel ya ubweya wa miyala ndi ulusi wachilengedwe wa miyala. Ulusi wa ubweya wa miyala uli ndi malo osungunuka kwambiri, makhalidwe okhazikika komanso kulimba kwamphamvu. Pali mipata yambiri yaing'ono pakati pa ulusi wa chinthu chachikulu cha ubweya wa miyala. Kumbali imodzi, kapangidwe kameneka kangathe kulepheretsa mpweya kugwedezeka ndikuchepetsa mphamvu ya kutentha.
Kumbali inayi, kukhalapo kwa mpweya wambiri m'malo opanda ulusi kumatha kulimbitsa mphamvu yotetezera kutentha kwa pepalalo. Malinga ndi kuwerengera, mphamvu yoyendetsera kutentha ya mapanelo a sandwich a ubweya wa miyala nthawi zambiri imakhala pakati pa 0.030-0.050W/(m·K). Mtundu uwu wa mbale yophatikizika imatha kuletsa bwino kutentha kwakunja pa kutentha kwamkati.
Chifukwa chake, ma sandwich panels a ubweya wa miyala, monga ma sandwich panels a polyurethane, ndi zipangizo zoyenera kwambiri zomangira zosungiramo zinthu zozizira. Zotsatira zenizeni za mapulojekiti ambiri osungiramo zinthu zozizira zikusonyeza kuti malo osungiramo zinthu zozizira omangidwa ndi ma sandwich panels a ubweya wa miyala amatha kutsimikizira bwino kutentha kwa zinthu zosungidwa. Nthawi yomweyo, zingathandizenso kukonza bwino ntchito ya makina oziziritsira ndikuchepetsa kugwiritsa ntchito mphamvu kwa malo osungiramo zinthu zozizira.
Kukana bwino kwambiri kwa moto kwa bolodi losungiramo ozizira la ubweya wa thanthwe
Poyerekeza ndi bolodi losungiramo zinthu zozizira la polyurethane, ubwino waukulu wa bolodi losungiramo zinthu zozizira la ubweya wa miyala uli mu kukana kwake moto bwino kwambiri. Zipangizo za mapanelo a sandwich a ubweya wa miyala ndi zitsulo ndi ulusi wa miyala, zomwe zonse ndi zoletsa moto komanso zoletsa moto. Pa kutentha kwambiri, ubweya wa miyala sudzawotcha kapena kutulutsa mpweya woopsa.
Kuchuluka kwa moto kwa mapanelo a sandwich a ubweya wa miyala kumatha kufika pa giredi A, zomwe ndi zabwino kuposa mapanelo a sandwich a Giredi B1 PIR ndi mapanelo a sandwich a Giredi B2 PU. Kulimba kwabwino kwa moto kumatsimikizira kuti mapanelo a sandwich a ubweya wa miyala ndi oyenera kwambiri misika monga United States ndi Europe yomwe imafuna kulimba kwa moto kwambiri m'nyumba.
Mphamvu yabwino yomanga ya bolodi losungiramo ozizira la ubweya wa thanthwe
Mu mapulojekiti osungira zinthu zozizira, mainjiniya nthawi zambiri amaika mafani ozizira pamwamba pa nyumba yosungiramo zinthu kuti azizire bwino. Nthawi yomweyo, kuti muwonjezere mphamvu yonyamula zinthu zozizira, nthawi zina pamafunika kuyika ma racks ndi zida zina pa nyumba yosungiramo zinthu. Izi zimafuna kuti bolodi losungiramo zinthu zozizira likhale ndi mphamvu inayake ndipo lizitha kunyamula kulemera kwina. Kuphatikiza apo, malo okhala ndi kutentha kochepa komanso chinyezi chambiri m'nyumba yosungiramo zinthu zozizira amafunikanso kulimba kwa zipangizo zomangira. Ma panel a masangweji a ubweya wa miyala amatha kukwaniritsa zosowa ziwirizi.
Chipinda cha masangweji cha ubweya wa miyala chimapangidwa ndi kuphatikiza kwa chipinda chachitsulo ndi chipinda chapakati cha ubweya wa miyala pogwiritsa ntchito njira yapadera. Chipindacho chili ndi zinthu zakuthupi monga zipilala zachitsulo ndi ulusi wa ubweya wa miyala, ndipo chili ndi mphamvu yolimba. Kuphatikiza apo, zinthu zake zakuthupi zimakhalabe zolimba pakapita nthawi. Kulimba bwino kumasunga malo osungiramo zinthu zozizira bwino komanso kumachepetsa ndalama zokonzera.
Yosavuta kuyiyika ndipo ingagwiritsidwenso ntchito
Ma sandwich panels a ubweya wa thanthwe ndi opepuka kulemera, osavuta kunyamula ndi kusamalira, ndipo ali ndi chiwopsezo chochepa chotaya. Kuphatikiza apo, panthawi yomanga, anthu adagwiritsa ntchito ma slicing kuti ayike ma sandwich panels pamodzi. Kupanga kokhazikika kwa ma sandwich panels a ubweya wa thanthwe kumatsimikizira kulondola kwa miyeso ndipo kumapangitsa kuti njira yoyikira ikhale yolondola komanso yogwira mtima. Opanga amatha kupanga ndikusintha mapepala awa mosavuta kuti akwaniritse zofunikira zina zosungiramo zozizira.
Ogwira ntchito amatha kugwiritsanso ntchito mapanelo a sandwich ngakhale atawachotsa, zomwe zimawonjezera phindu la pulojekitiyi.
Zoyipa za bolodi losungiramo ozizira la ubweya wa thanthwe
Ngakhale kuti matabwa osungiramo zinthu zozizira a ubweya wa miyala ali ndi ntchito yabwino kwambiri, alinso ndi zovuta zake. Chida chachikulu cha sandwich panel ya ubweya wa miyala ndi ubweya wa miyala wopangidwa ndi makina okanikiza ulusi wa miyala. Komabe, kulumikizana pakati pa ulusi sikuli pafupi, ndipo pakapita nthawi, ulusi womwe uli m'mphepete mwake umasweka ndikugwa. Cholakwika ichi chimawononga umphumphu wa bolodi, zomwe zimapangitsa kuti nthunzi ya madzi ilowe ndikuchepetsa mphamvu yake yotetezera kutentha.
Pofuna kuthetsa vutoli, pakadali pano pali njira ziwiri zothetsera vutoli. Limodzi ndi kugwiritsa ntchito chimango chachitsulo chotsekedwa. Anthu amaika mbale zachitsulo mbali zonse ziwiri za gulu la masangweji a ubweya wa miyala kuti akonze mbali ziwiri za chipika cha ubweya wa miyala chomwe chimatha kugwa mosavuta komanso kutayikira. Lina ndi kuthira thovu la polyurethane mbali zonse ziwiri za chipika cha ubweya wa miyala. Opanga amakonza chipika cha ubweya wa miyala pokulitsa zinthu za polyurethane pa kutentha kwambiri.
