Atlanta, GA - Kuyambira pa Seputembala 30 mpaka Okutobala 2, Omni Hotel ku Centennial Park idzakhala ndi msonkhano waukadaulo wa 2024 Polyurethanes, kubweretsa akatswiri otsogola ndi akatswiri ochokera kumakampani a polyurethane padziko lonse lapansi. Wokonzedwa ndi American Chemistry Council's Center for the Polyurethanes Industry (CPI), msonkhanowu cholinga chake ndi kupereka nsanja yamaphunziro ndikuwonetsa zatsopano zaukadaulo wa polyurethane.

Polyurethanes amadziwika kuti ndi imodzi mwazinthu zosunthika kwambiri zamapulasitiki zomwe zilipo masiku ano. Mapangidwe awo apadera a mankhwala amawalola kuti azitha kugwiritsidwa ntchito mosiyanasiyana, kuthetsa mavuto ovuta komanso kupangidwa m'mawonekedwe osiyanasiyana. Kusinthasintha kumeneku kumawonjezera zinthu zamafakitale ndi ogula, kuwonjezera chitonthozo, kutentha, komanso kumasuka ku moyo watsiku ndi tsiku.

Kupanga kwa polyurethanes kumaphatikizapo kuchitapo kanthu kwa mankhwala pakati pa ma polyols-zakumwa zoledzeretsa zokhala ndi magulu opitilira awiri a hydroxyl-ndi ma diisocyanates kapena ma polymeric isocyanates, omwe amathandizidwa ndi zopangira zoyenera ndi zowonjezera. Kusiyanasiyana kwa ma diisocyanate ndi ma polyols omwe amapezeka kumathandizira opanga kupanga zinthu zambiri zofananira ndi ntchito zina, zomwe zimapangitsa kuti ma polyurethanes akhale ofunikira m'mafakitale ambiri.

Ma polyurethanes amapezeka ponseponse m'moyo wamakono, omwe amapezeka muzinthu zosiyanasiyana kuyambira pa matiresi ndi makochi mpaka zida zotsekera, zokutira zamadzimadzi, ndi utoto. Amagwiritsidwanso ntchito mu ma elastomer olimba, monga mawilo odzigudubuza, zoseweretsa zofewa za thovu, ndi ulusi wotanuka. Kufalikira kwawo kumatsimikizira kufunikira kwawo pakupititsa patsogolo magwiridwe antchito komanso kutonthoza kwa ogula.

Chemistry yopangidwa ndi polyurethane makamaka imaphatikizapo zida ziwiri zofunika: methylene diphenyl diisocyanate (MDI) ndi toluene diisocyanate (TDI). Mankhwalawa amachitira ndi madzi m'chilengedwe kuti apange ma polyureas olimba a inert, kusonyeza kusinthasintha ndi kusinthasintha kwa chemistry ya polyurethane.

Msonkhano Waumisiri wa 2024 Polyurethanes ukhala ndi magawo angapo opangidwa kuti aphunzitse opezekapo za kupita patsogolo kwaposachedwa m'munda. Akatswiri adzakambirana zochitika zomwe zikubwera, ntchito zatsopano, ndi tsogolo la teknoloji ya polyurethane, kupereka zidziwitso zamtengo wapatali kwa akatswiri amakampani.

Pamene msonkhano ukuyandikira, otenga nawo mbali akulimbikitsidwa kuti azigwirizana ndi anzawo, kugawana nzeru, ndi kufufuza mwayi watsopano mkati mwa gawo la polyurethane. Chochitikachi chikulonjeza kuti chidzakhala msonkhano waukulu kwa iwo omwe akukhudzidwa ndi chitukuko ndi kugwiritsa ntchito zipangizo za polyurethane.
