Ma panelo a masangweji akhala ofunikira kwambiri pakupanga kwamakono chifukwa cha kutentha kwawo kotentha, mphamvu ya kapangidwe kake, komanso kugwiritsa ntchito bwino malo oikamo. Pakati pa mitundu yosiyanasiyana ya mapanelo a masangweji, omwe ali ndi zinthu za polyurethane (PIR) ndi omwe amakondedwa kwambiri m'mafakitale ambiri chifukwa cha magwiridwe antchito awo apamwamba. Monga opanga ma catalyst a polyurethane ogwira ntchito kwambiri, timanyadira kuthandizira kupanga mapanelo awa kudzera mu njira zodalirika komanso zogwira mtima mongaMXC-T, MXC-C15,ndiMXC-37.
Kodi Ma Sandwich Panels Ndi Chiyani?
Ma panelo a masangweji ndi zipangizo zomangira zopangidwa ndi zigawo zitatu: chinthu cholimba kwambiri, mongapolystyrene yowonjezera (EPS), ubweya wa mchere,orpolyurethane (PIR), ndi zigawo ziwiri zakunja za khungu, zomwe nthawi zambiri zimapangidwa ndi mapepala achitsulo. Kapangidwe ka zigawozi kamapereka mphamvu zambiri poyerekeza ndi kulemera, zomwe zimapangitsa kuti mapanelo akhale abwino kwambiri pazinthu zosiyanasiyana za kapangidwe kake komanso zotetezera kutentha.
Chifukwa chiyani ma panel a polyurethane (PIR) sandwich?
Pakati pa mitundu yosiyanasiyana ya zipangizo zotetezera kutentha,polyisocyanurate (PIR)Ma sandwich panels opangidwa ndi zinthu zosiyanasiyana amadziwika kwambiri chifukwa chakutentha kochepa,kutanthauza kuti amapereka chitetezo chabwino ndi mapanelo opyapyala. Zotsatira zake zimakhala kugwiritsa ntchito mphamvu moyenera, zomwe ndizofunikira kwambiri pa:
- Malo osungiramo zinthu zozizira komanso mafakitale opangira chakudya
- Nyumba zamafakitale ndi zamalonda
- Madenga ndi makoma ophimba
- Nyumba zomangidwa kale komanso nyumba zomangidwa modular
- Kukonzanso nyumba ndi kukonzanso nkhope
Ma sandwich a polyurethane ali ndi ubwino wina, kuphatikizapo:
- Kukana moto
- Yopepuka komanso yosavuta kugwiritsa ntchito
- Kukhalitsa komanso kukhala ndi moyo wautali
- Kukana chinyezi
Udindo waZothandizira za Polyurethanemu Kupanga Ma Sandwich Panel
Ma catalyst a polyurethane amaseweraudindo wofunikirapopanga ma sandwich panels. Ma catalyst awa amafulumizitsa kuchitapo kanthu pakati pama polyol ndi isocyanates,kulola njira yowongolera thovu ndi kuyeretsa yomwe imafunika kuti ipange PIR core.
At Zipangizo Zatsopano za Mingxu, timapereka mitundu yosiyanasiyana ya ma catalyst apadera a polyurethane opangidwira ntchito za sandwich panel, kuphatikizapo:
- MXC-T:Chothandizira chodalirika cha gelling chomwe chimalimbikitsa machitidwe achangu komanso ofanana a urethane. Chimathandiza kuwongolera nthawi yopanda kugwedezeka komanso chimatsimikizira kapangidwe kabwino ka thovu panthawi yopanga.
- MXC-C15:Chothandizira cha amine chomwe chimadziwika bwino chifukwa cha kukonza kuuma kwa pamwamba ndi kuyenda kwa thovu. Chimathandiza kuti zinthu zikhale bwino komanso chimachepetsa zolakwika pa pamwamba.
- MXC-37:Chothandizira ichi, chomwe chapangidwa kuti chigwiritsidwe ntchito popanga mpweya wochepa komanso wogwira ntchito bwino, chimawonjezera kusinthasintha kwa madzi ndikuwonetsetsa kuti gulu lomalizidwa likugwira ntchito bwino kwambiri.
Pamodzi, zinthu zothandizira izi zimatsimikizirakuwongolera bwino momwe zinthu zilili, kukwera kwa thovu kofanana,ndikhalidwe lokhazikika la kutchinjiriza, kukwaniritsa miyezo yapamwamba yofunikira pa zipangizo zamakono zomangira.
Tigwirizaneni nafe pa Zosowa Zanu za Sandwich Panel Catalyst
Pamene kufunikira kwa zipangizo zomangira zomwe sizimawononga mphamvu zambiri komanso zogwira ntchito bwino kukukula, mapanelo a sandwich a polyurethane apitiliza kukhala yankho lofunika kwambiri.wopanga masangweji, tikukulandirani kuti mukambirane nafe za njira zathu zothanirana ndi mavuto.
Gulu lathu limaperekachithandizo chaukadaulo, chitsogozo cha kapangidwe kake,ndikupereka mwachangu padziko lonse lapansiza ma catalyst apamwamba a polyurethane. Kaya mukukonzekera bwino mtundu wa mankhwala omwe alipo kale kapena kupanga mitundu yatsopano, ukatswiri wathu ungakuthandizeni kukwaniritsakupanga bwino komanso magwiridwe antchito abwino kwambiri oteteza kutentha.
