Atlanta, GA – Ho tloha ka la 30 Loetse ho isa la 2 Mphalane, Hotele ea Omni e Centennial Park e tla tšoara Seboka sa Botekgeniki sa Polyurethanes sa 2024, se kopanyang litsebi tse etellang pele le litsebi tse tsoang indastering ea polyurethane lefatšeng ka bophara. Seboka sena, se hlophisitsoeng ke Setsi sa Lekhotla la K'hemistri la Amerika bakeng sa Indasteri ea Polyurethanes (CPI), se ikemiselitse ho fana ka sethala sa lithuto tsa thuto le ho bonts'a boqapi ba morao-rao k'hemistri ea polyurethane.

Li-polyurethane li tsejoa e le e 'ngoe ea thepa ea polasetiki e feto-fetohang ka ho fetisisa e fumanehang kajeno. Litšobotsi tsa tsona tse ikhethang tsa lik'hemik'hale li li lumella ho etsoa bakeng sa mefuta e mengata ea lits'ebetso, ho rarolla liphephetso tse rarahaneng le ho bōptjoa ka libopeho tse fapaneng. Ho ikamahanya le maemo hona ho ntlafatsa lihlahisoa tsa indasteri le tsa bareki, ho eketsa boiketlo, mofuthu le boiketlo bophelong ba letsatsi le letsatsi.

Tlhahiso ea li-polyurethane e kenyelletsa karabelo ea lik'hemik'hale pakeng tsa li-polyol—lino tse nang le lihlopha tse fetang tse peli tsa hydroxyl tse arabelang—le li-diisocyanate kapa li-isocyanate tsa polymeric, tse thusoang ke li-catalyst le li-additives tse loketseng. Mefuta e fapaneng ea li-diisocyanate le li-polyol tse fumanehang e nolofalletsa bahlahisi ho theha mefuta e mengata ea thepa e etselitsoeng lits'ebetso tse itseng, e leng se etsang hore li-polyurethane li be karolo ea bohlokoa liindastering tse ngata.

Li-polyurethane li fumaneha hohle bophelong ba sejoale-joale, li fumanoa lihlahisoa tse fapaneng ho tloha materaseng le lisofeng ho ea ho thepa ea ho kenya mocheso, lipente tse metsi le lipente. Li boetse li sebelisoa ho li-elastomer tse tšoarellang, tse kang mabili a roller blade, lintho tsa ho bapala tse bonolo tse tenyetsehang tsa foam, le likhoele tse tenyetsehang. Boteng ba tsona bo atileng bo totobatsa bohlokoa ba tsona ho ntlafatseng ts'ebetso ea sehlahisoa le boiketlo ba bareki.

Khemikhale e ka morao ho tlhahiso ea polyurethane e kenyelletsa haholo-holo thepa e 'meli ea bohlokoa: methylene diphenyl diisocyanate (MDI) le toluene diisocyanate (TDI). Metsoako ena e arabela le metsi tikolohong ho theha li-polyurea tse tiileng tse sa sebetseng, e leng se bontšang ho tenyetseha le ho ikamahanya le maemo ha k'hemistri ea polyurethane.

Seboka sa Theknoloji sa Polyurethanes sa 2024 se tla ba le mefuta e fapaneng ya dithuto tse reretsweng ho ruta ba tlileng kopanong ka kgatelopele ya moraorao lefapheng lena. Ditsebi di tla buisana ka mekgwa e ntseng e hlaha, ditshebediso tse ntjha, le bokamoso ba theknoloji ya polyurethane, di fane ka temohisiso ya bohlokwa bakeng sa ditsebi tsa indasteri.

Ha kopano e ntse e atamela, barupeluoa ba khothalletsoa ho sebelisana le lithaka, ho arolelana tsebo le ho hlahloba menyetla e mecha ka har'a lekala la polyurethane. Ketsahalo ena e tšepisa ho ba kopano ea bohlokoa bakeng sa ba amehang ntlafatsong le ts'ebelisong ea thepa ea polyurethane.
