Kugwiritsa Ntchito Ma Catalyst a Polyurethane mu Sandwich Panels

Mapanelo a sandwich a polyurethane, omwe amadziwika kuti mapanelo a PU, amagwiritsidwa ntchito kwambiri pakupanga ndi mafakitale amakono chifukwa cha mphamvu zawo, kulimba kwawo komanso mphamvu zawo zotetezera kutentha. Mapanelowa amapangidwa ndi zigawo zitatu zazikulu: maziko a thovu la polyurethane omwe amateteza kwambiri kutentha ndipo amamangiriridwa pakati pa mapepala awiri olimba achitsulo. Kapangidwe kameneka kamakhala ndi kukhazikika kwabwino kwa kapangidwe kake, kutetezera kutentha komanso kukana nyengo, zomwe zimapangitsa kuti ikhale yoyenera malo osiyanasiyana. Zinthu zopangira polyurethane popanga mapanelo awa zimatsimikizira kuti ma cores a thovu amapangidwa bwino komanso amagwira ntchito bwino.

Kodi Sandwich Panel ndi chiyani?

Gulu la sandwich ndi mtundu wa zipangizo zomangira zomwe zimaphatikiza pakati pa thovu la polyurethane ndi zigawo zakunja, nthawi zambiri chitsulo, kuti apange zinthu zophatikizika bwino kwambiri. Pakati pa thovu, lopangidwa kudzera mu mankhwala omwe amathandizidwa ndi ma catalyst a polyurethane, limapereka chitetezo chabwino kwambiri, kuthandiza kusunga kutentha kwamkati kokhazikika m'nyumba ndi zida. Zigawo zakunja zachitsulo zimawonjezera kulimba kwa kapangidwe kake, chitetezo, komanso kulimba. Kuphatikiza kumeneku kumapereka yankho lopepuka koma lolimba pamakoma, padenga, posungira zinthu zozizira, ndi zina zomwe zimagwiritsidwa ntchito komwe kugwiritsa ntchito mphamvu moyenera, kulemera, ndi mphamvu ndizofunikira.

Udindo wa Polyurethane Catalysts mu Sandwich Panels

Ma catalyst a polyurethane ndi ofunikira kwambiri popanga maziko a thovu la mapanelo a sandwich. Ma catalyst monga MXC-T ndi MXC-C15, iliyonse yokhala ndi mawonekedwe osiyana, imathandizira kuyanjana pakati pa ma polyol ndi isocyanates, zomwe zimapangitsa kuti thovu lipangidwe ndi kuchuluka ndi kapangidwe komwe kukufunika.

1.MXC-Timagwiritsidwa ntchito makamaka popanga thovu lofewa lochokera ku polyether, thovu lopangidwa, thovu lolimba pang'ono, ndi thovu lolimba. Mu ma sandwich panels, MXC-T imathandiza kuwongolera kapangidwe ka thovu, kupereka liwiro loyenera la reaction komanso kapangidwe ka maselo kogwirizana. Kusasinthasintha kumeneku kumatsimikizira kutentha kofanana komanso kumawonjezera umphumphu wa panel.

2.MXC-C15, chothandizira amine, ndi choyenera kwambiri popanga thovu lofewa komanso lofewa komanso lolimba. Mu ma sandwich panels, zimathandiza kuti thovu likhale lolimba lomwe limasunga mphamvu zake zotetezera kutentha pansi pa kutentha kosiyanasiyana. Kulamulira kwa MXC-C15 pa zomwe zimachitika kumathandiza kuti thovu likhale lolimba komanso lolimba, zomwe zimapangitsa kuti ma boardwo akhale olimba kwambiri ku kusintha kwa kutentha komanso kupsinjika kwa chilengedwe.

Kugwiritsa ntchito ma PU Sandwich Panels

Ma sandwich a polyurethane amagwiritsidwa ntchito kwambiri m'malo osungiramo zinthu ozizira, m'nyumba zamafakitale, m'nyumba zamalonda, komanso m'malo osungiramo zinthu m'firiji, komwe kusunga kutentha ndikofunikira kwambiri. Ma sandwich a polyurethane ndi opepuka, ofulumira kuyika, osalemera kwambiri, komanso opirira nyengo yoipa kuti azitha kugwira ntchito kwa nthawi yayitali. Kugwiritsa ntchito ma catalyst apadera a polyurethane popanga zinthu kumawonjezera zinthuzi, zomwe zimapangitsa kuti ma sandwich a polyurethane akhale chisankho chachikulu cha njira zomangira zogwiritsira ntchito mphamvu zochepa komanso zolimba.

Mwachidule, kuphatikiza thovu la polyurethane ndi zinthu zoyambitsa mphamvu monga MXC-T ndi MXC-C15 kumapanga mapanelo a sandwich okhala ndi kutchinjiriza kwabwino, mphamvu komanso kukana nyengo, zomwe zimathandiza njira zomangira zokhazikika komanso zogwira mtima.
