Kugwiritsa Ntchito Ma Catalyst a Polyurethane mu Foam Yotseguka ya Polyurethane

Thovu la polyurethane ndi chinthu chogwiritsidwa ntchito kwambiri komanso chogwiritsidwa ntchito kwambiri, chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Chimagwiritsidwa ntchito m'mipando yambiri yamkati ku United States ndi kunja, makamaka m'makampani opanga mipando, komwe kumapezeka kuchulukana ndi kuuma kosiyanasiyana kuti chikhale choyenera kugwiritsidwa ntchito m'njira zosiyanasiyana, zomwe nthawi zambiri zimagwiritsidwa ntchito popanga upholstery, matiresi, ma cushion ndi insulation. Thovu la polyurethane lotseguka, makamaka, ndi lofewa, losinthasintha komanso lopepuka, zomwe zimapangitsa kuti likhale chisankho choyamba cha zinthu zomwe zimafuna chitonthozo ndi kulimba. Kapangidwe ka thovu ili kokhala ndi mabowo kumawonjezera mphamvu zake zotetezera kutentha komanso phokoso, zomwe zimapangitsa kuti likhale loyenera kugwiritsidwa ntchito m'njira zosiyanasiyana kuyambira kukongoletsa mkati mpaka kuzinthu zotetezera kutentha.

Zothandizira mongaMXC-A33ndipo MXC-T imagwira ntchito yofunika kwambiri popanga thovu la polyurethane lotseguka. Ma catalyst awa amathandizira njira yotulutsa thovu mwa kufulumizitsa momwe mankhwala amachitira pakati pa isocyanates, monga toluene diisocyanate kapena TDI, ndi polyols. Ntchito yawo ndikuwonetsetsa kuti thovu limapanga kapangidwe kake ka maselo otseguka, zomwe zimapangitsa kuti likhale ndi zinthu zomwe zimapuma komanso zotanuka.

MXC-A33 ingagwiritsidwe ntchito pa thovu lofewa, lolimba komanso lolimba pang'ono. Imathanso kusungunula zosungunulira zina monga MEG, DEG, BDO, ndi zina zotero, pa ntchito zosiyanasiyana.

MXC-Timagwiritsidwa ntchito popanga thovu losinthasintha la polyether, thovu lopangidwa, thovu lolimba pang'ono komanso thovu lolimba. Imagwiritsidwa ntchito makamaka m'magalimoto.

Thovu la polyurethane lotseguka limagwiritsidwa ntchito kwambiri m'ma cushion a mipando yamkati ndi yakunja, matiresi a thovu lokumbukira, ma cushion a mipando komanso ngakhale ma phukusi azachipatala chifukwa cha kuthekera kwake kokwanira mawonekedwe a thupi ndikupereka chitonthozo. Kufewa kwake komanso kusinthasintha kwake, kuphatikiza ndi mphamvu zabwino kwambiri zotetezera kutentha ndi phokoso, zimapangitsa kuti likhale chisankho chodziwika bwino chotetezera kutentha kosawononga mphamvu m'nyumba.

Mwachidule, kugwiritsa ntchito ma catalyst a polyurethane monga MXC-A33 ndi MXC-T popanga ma thovu otseguka kumathandizira kuti thovu ligwire bwino ntchito, kuonetsetsa kuti chinthu chomaliza chikukwaniritsa zofunikira pa ntchito zosiyanasiyana monga mipando ndi zinthu zotetezera kutentha. Kampani ya Mingxu Chemical yakhala ikupanga ma catalyst a polyurethane kwa zaka zoposa 20, tili ndi njira yabwino kwambiri yochitira zinthu komanso gulu la akatswiri kuti tikonze ndikusinthira zinthu zothandizira pamsika, pali makasitomala ambiri olandirika kuti abwere kudzafunsa mafunso.
