Atlanta, GA – Kuyambira pa Seputembala 30 mpaka Okutobala 2, Omni Hotel ku Centennial Park idzachita Msonkhano wa Ukadaulo wa Polyurethanes wa 2024, womwe udzabweretse akatswiri otsogola komanso akatswiri ochokera kumakampani opanga polyurethane padziko lonse lapansi. Msonkhanowu, womwe unakonzedwa ndi American Chemistry Council's Center for the Polyurethanes Industry (CPI), cholinga chake ndi kupereka nsanja ya maphunziro ndikuwonetsa zatsopano za polyurethane chemistry.

Ma polyurethane amadziwika kuti ndi chimodzi mwa zipangizo zapulasitiki zogwiritsidwa ntchito kwambiri masiku ano. Makhalidwe awo apadera a mankhwala amawalola kuti agwiritsidwe ntchito m'njira zosiyanasiyana, kuthetsa mavuto ovuta komanso kupangidwa m'njira zosiyanasiyana. Kusinthasintha kumeneku kumawonjezera zinthu zamafakitale ndi zamakasitomala, kuwonjezera chitonthozo, kutentha, komanso kusavuta kugwiritsa ntchito pa moyo watsiku ndi tsiku.

Kupanga ma polyurethanes kumaphatikizapo kusintha kwa mankhwala pakati pa ma polyols—mowa wokhala ndi magulu opitilira awiri a hydroxyl—ndi ma diisocyanates kapena ma polymeric isocyanates, omwe amathandizidwa ndi ma catalysts ndi zowonjezera zoyenera. Kusiyanasiyana kwa ma diisocyanates ndi ma polyols omwe alipo kumathandiza opanga kupanga zinthu zosiyanasiyana zomwe zimagwirizana ndi ntchito zinazake, zomwe zimapangitsa kuti ma polyurethane akhale ofunikira m'mafakitale ambiri.

Ma polyurethane amapezeka paliponse m'moyo wamakono, amapezeka m'zinthu zosiyanasiyana kuyambira matiresi ndi masofa mpaka zinthu zotetezera kutentha, zokutira zamadzimadzi, ndi utoto. Amagwiritsidwanso ntchito mu ma elastomer olimba, monga mawilo a roller blade, zoseweretsa zofewa zofewa za thovu, ndi ulusi wosalala. Kupezeka kwawo kwakukulu kukuwonetsa kufunika kwawo pakukweza magwiridwe antchito azinthu komanso chitonthozo cha ogula.

Kapangidwe ka polyurethane kamene kamapanga polyurethane kamakhala ndi zinthu ziwiri zofunika kwambiri: methylene diphenyl diisocyanate (MDI) ndi toluene diisocyanate (TDI). Mankhwalawa amakumana ndi madzi m'chilengedwe kuti apange ma polyurea olimba, zomwe zimasonyeza kusinthasintha komanso kusinthasintha kwa mankhwala a polyurethane.

Msonkhano wa Ukadaulo wa Polyurethanes wa 2024 udzakhala ndi magawo osiyanasiyana opangidwira kuphunzitsa omwe akupezekapo za kupita patsogolo kwaposachedwa pantchitoyi. Akatswiri adzakambirana za zomwe zikuchitika, njira zatsopano zogwiritsira ntchito, komanso tsogolo la ukadaulo wa polyurethane, zomwe zipereka chidziwitso chofunikira kwa akatswiri pantchitoyi.

Pamene msonkhano ukuyandikira, ophunzira akulimbikitsidwa kuti agwirizane ndi anzawo, kugawana chidziwitso, ndikupeza mwayi watsopano mkati mwa gawo la polyurethane. Chochitikachi chikulonjeza kukhala msonkhano wofunika kwambiri kwa iwo omwe akugwira ntchito yopanga ndi kugwiritsa ntchito zipangizo za polyurethane.
