Ma catalyst a polyurethane amagwira ntchito yofunika kwambiri popanga ma sandwich panels, mafelemu olimba a thovu ndi zinthu zokongoletsera, zomwe zingathandize kuti thovu la polyurethane ligwire bwino ntchito komanso kuti ligwire bwino ntchito. Ma catalyst omwe amagwiritsidwa ntchito pa ntchito izi ndi MXC-8 (DMCHA) ndi MXC-41, zomwe zimathandiza kupanga thovu lolimba, lopepuka komanso logwira ntchito bwino.
MXC-8 (DMCHA):Chothandizira Chosiyanasiyana Chogwiritsira Ntchito Thovu Lolimba
MXC-8, yomwe imadziwikanso kutiDMCHA(Dimethylcyclohexylamine), ndi chothandizira chogwira ntchito kwambiri chochokera ku amine chomwe chimagwiritsidwa ntchito kwambiri popanga thovu lolimba la polyurethane, kuphatikizapomapanelo a masangwejindimafelemu a mipando.
Ubwino Waukulu wa MXC-8 (DMCHA) Pakupanga Thovu:
Nthawi Yochira Mwachangu: DMCHA imafulumizitsa njira yophikira makina a polyurethane, kuthandiza opanga kupanga thovu lolimba mwachangu, mongakupanga chimango cha mipando.
Kapangidwe ka Thovu Kokonzedwa Bwino: MXC-8 imathandizira kupangika kwa maselo abwino, ofanana mu thovu, zomwe zimapangitsa kutimphamvu yokakamiza ndikukhazikika kwa mawonekedwe za chinthu chomaliza. Izi ndizofunikira pa ntchito monga mafelemu olimba a mipando ya thovu, komwe kulimba kwa kapangidwe kake ndikofunikira kwambiri kuti zitsimikizire kulimba ndi moyo wautumiki.
Kusinthasintha kwa Ntchito: Kuwonjezera pa mapanelo a masangweji, MXC-8 imagwiritsidwanso ntchito m'zigawo zina zokongoletsera za thovu, zomwe zimathandiza kupanga zinthu zopepuka koma zolimba popanga mipando ndi zinthu zomangamanga. Zimasungunuka m'ma polyol ambiri ndi zosungunulira zachilengedwe, koma kwenikweni sizisungunuka m'madzi. Zingagwiritsidwe ntchito ngati chothandizira pa ntchito zosiyanasiyana kuphatikizapo mitundu yonse ya thovu lolimba lopaka.
Kuchepetsa Zinyalala ndi KusasinthasinthaMwa kufulumizitsa kuchitapo kanthu pakati papolyolndiisocyanatePogwiritsira ntchito zigawo zake, MXC-8 imathandiza kusunga mphamvu za thovu nthawi zonse, kuchepetsa zinyalala ndikuonetsetsa kuti chinthu chomaliza chikugwirizana.
MXC-41:Mphamvu Yapamwamba Yotulutsa Thovu pa Machitidwe Ogwirizana ndi Madzi
Chinthu china chofunikira kwambiri popanga thovu lolimba la polyurethane, makamaka mumapanelo a masangwejindiMXC-41. Yodziwika ndi mphamvu yake yabwino kwambiri yotulutsa thovu, MXC-41 imagwira ntchito bwino kwambiri mumachitidwe olimba ogwirizana ndi madzi, komwe madzi amagwiritsidwa ntchito popangaCO2mpweya, zomwe zimapangitsa kuti thovu lifalikire panthawi yokonza.
Ubwino Waukulu wa MXC-41 Pakupanga Thovu:
Kutha Kwambiri Kutulutsa Thovu: MXC-41 imagwira ntchito bwino m'makina omwe amagwiritsa ntchito madzi ngati chothandizira kutulutsa thovu, kuonetsetsa kuti thovu likukulirakulira bwino komanso mofanana. Mphamvu yotulutsa thovu imeneyi ndi yofunika kwambiri popanga mapanelo a sandwich, chifukwa kapangidwe ka selo kofanana ndi kofunikira pa kutenthetsa kutentha komanso mphamvu ya makina.
Kapangidwe Kowonjezereka: Kapangidwe ka thovu ka chothandizirachi kamathandiza kupanga thovu lolimba lomwe silimangokhala lopepuka komanso lotha kunyamula katundu wambiri komanso lolimba, zomwe zimapangitsa kuti likhale losankha kwambiri pakupanga zinthu monga mapanelo a sandwich ndi mafelemu a mipando.
Kugwiritsa Ntchito mu Sandwich Panels ndi Furemu za Mipando
Mapanelo a MasangwejiZonse ziwiriMXC-8 (DMCHA)ndiMXC-41ndizofunikira kwambiri pakupangamapanelo a masangweji, zomwe zimakhala ndi thovu lolimba lokhala pakati pa zigawo ziwiri za zinthu (nthawi zambiri chitsulo kapena pulasitiki). Mapanelo awa amagwiritsidwa ntchito kwambiri pomanga, kutchinjiriza, ndi mayendedwe chifukwa chakatundu woteteza kutenthandimphamvu yamakina. MXC-8 imathandiza kukwaniritsakuchira mwachangundikupangika kwa thovu lokhazikika, pomwe MXC-41 imatsimikizira kuti thovubwino kutulutsa thovundi kukhazikika kwa kapangidwe kake konse.
Mafelemu Olimba a Mipando ya Thovu: Thethovu lolimbaamagwiritsidwa ntchito mumafelemu a mipandoKupindula ndi mphamvu zogwira ntchito mwachangu komanso mphamvu zamakina zomwe zimaperekedwa ndi MXC-8. Zinthu zimenezi zimathandiza kupanga mipando yopepuka komanso yolimba yomwe imagwira ntchito bwino komanso yokongola.
Mbali ZokongoletseraKuwonjezera pa ntchito zomangira, MXC-8 ndi MXC-41 zimagwiritsidwanso ntchito popangaziwalo zokongoletsa za thovuza mipando ndi kapangidwe ka mkati. Kusinthasintha kwa zinthuzi kumapangitsa kuti thovu likhale lolimbamawonekedwe abwinopamene aliwopepukandiwolimba mtima.
Mapeto
Kugwiritsa ntchito ma catalyst a MXC-8 (DMCHA) ndi MXC-41 popanga ma sandwich panels, mafelemu olimba a thovu ndi zinthu zokongoletsera kumawongolera magwiridwe antchito, kulimba komanso kugwira ntchito bwino kwa makina a thovu la polyurethane. Pamodzi, ma catalyst awa ndi ofunikira popanga ma thovu ogwira ntchito kwambiri omwe amakwaniritsa zosowa zofunika kwambiri zamakampani amakono omanga, mipando ndi mapangidwe.
