Mafoam a polyurethane ndi zinthu zofunika kwambiri m'mafakitale osiyanasiyana chifukwa cha mphamvu zawo zosiyanasiyana, kuyambira kutenthetsa mpaka kulongedza. Chothandizira chomwe chimagwiritsidwa ntchito popanga thovu chimagwira ntchito yofunika kwambiri pakutanthauzira makhalidwe awa.MXC-37, yomwe imadziwikanso kuti 2-[2-(Dimethylamino)ethoxy]ethanol (DMAEE), ndi chothandizira chapadera cha tertiary amine chomwe chatchuka chifukwa cha magwiridwe ake abwino kwambiri popanga thovu lolimba la polyurethane, makamaka popanga mankhwala omwe amafuna madzi ambiri.
Zinthu Zofunika Kwambiri za MXC-37
MXC-37 imadziwika ndi ntchito yake yotulutsa thovu kwambiri, zomwe zimapangitsa kuti ikhale yabwino kwambiri popanga mapangidwe a thovu lopaka mafuta ochepa. Kutha kwake kugwira ntchito bwino m'machitidwe okhala ndi madzi ambiri kumalola kupanga mapangidwe otseguka a maselo, omwe amafunidwa kwambiri mu ntchito za thovu la polyurethane (SPF). Mosiyana ndi zachikhalidwe, thovu la polyurethane limagwiritsidwa ntchito.zoyambitsa zochokera ku amine, Kapangidwe ka mankhwala kapadera ka MXC-37, komwe kumaphatikizapo haidrojeni yogwira ntchito, kamathandiza kuti igwirizane ndi matrix ya polymer. Kuphatikiza kumeneku kumachepetsa kwambiri fungo la amine lomwe limagwirizanitsidwa ndi thovu la polyurethane, zomwe zimapangitsa kuti likhale losavuta kugwiritsa ntchito.
Kusinthasintha ndi Kugwiritsa Ntchito
MXC-37 sikuti imangogwiritsidwa ntchito popanga thovu lolimba; imapezekanso mu thovu lofewa la thovu ndi polyether polyurethane soft block thovu. Mawonekedwe ake opanda mtundu kapena achikasu pang'ono kutentha kwa chipinda, kuphatikiza ndi kusungunuka kwake m'madzi, zimapangitsa kuti ikhale chisankho chosavuta kwa opanga. Mu ntchito za SPF, MXC-37 ingagwiritsidwe ntchito ngati chothandizira chachikulu, komanso imagwiranso ntchito ngati chothandizira chabwino kwambiri ikaphatikizidwa ndi zinthu zina zothandizira, monga zomwe zimachokera ku BDMAEE. Pogwiritsa ntchito MXC-37, opanga amatha kuchepetsa kudalira zinthu zothandizira thovu zachikhalidwe, zomwe zingachepetse ndalama zopangira ndikukweza mtundu wa thovu.
Ubwino wa Zachilengedwe ndi Kuzindikira
Chimodzi mwa zinthu zodabwitsa za MXC-37 ndi kuthekera kwake kuchepetsa fungo la chinthu chomalizidwa cha polyurethane. Izi zimachitika kudzera mu kuphatikiza kwa MXC-37 mu kapangidwe ka polima, komwe kumachepetsa kuchuluka kwa amine komwe kumayambitsa fungo lodziwika bwino. Zotsatira zake, chinthu chomalizidwa sichimangokhala choteteza chilengedwe komanso chosangalatsa kwa ogula ndi ogwiritsa ntchito.
Pomaliza, MXC-37 ndi chothandizira chogwira ntchito mosiyanasiyana komanso chothandiza chomwe chimapereka ubwino waukulu popanga thovu lolimba la polyurethane. Ntchito yake yotulutsa thovu kwambiri, kugwirizana ndi madzi ambiri, komanso kuthekera kwake kuchepetsa fungo zimapangitsa kuti ikhale chisankho chabwino kwambiri pa ntchito zosiyanasiyana mumakampani opanga polyurethane. Kaya imagwiritsidwa ntchito yokha kapena ngati chothandizira, MXC-37 ikukonzekera kukulitsa magwiridwe antchito ndi kukongola kwa thovu la polyurethane.
