Atlanta, GA - Ho tloha ka la 30 Loetse ho isa la 2 Mphalane, Omni Hotel e Centennial Park e tla amohela Seboka sa Tekheniki sa Polyurethanes sa 2024, se kopanyang litsebi tse etelletseng pele le litsebi tse tsoang indastering ea polyurethane lefatšeng ka bophara. E hlophisitsoe ke Setsi sa American Chemistry Council bakeng sa Indasteri ea Polyurethanes (CPI), seboka sena se ikemiselitse ho fana ka sethala sa liboka tsa thuto le ho bonts'a mekhoa ea morao-rao ea k'hemistri ea polyurethane.

Polyurethanes e nkoa e le e 'ngoe ea lisebelisoa tsa polasetiki tse sebetsang ka ho fetisisa tse fumanehang kajeno. Lik'hemik'hale tsa bona tse ikhethang tsa lik'hemik'hale li ba lumella hore ba lokisetsoe mefuta e mengata ea lisebelisoa, ho rarolla mathata a rarahaneng le ho bōptjoa ka libopeho tse sa tšoaneng. Ho ikamahanya le maemo ho ntlafatsa lihlahisoa tsa indasteri le tsa bareki, ho eketsa boiketlo, mofuthu, le boiketlo bophelong ba letsatsi le letsatsi.

Tlhahiso ea polyurethanes e kenyelletsa karabelo ea lik'hemik'hale lipakeng tsa polyols - joala bo nang le lihlopha tse fetang tse peli tse sebetsang tsa hydroxyl - le diisocyanates kapa polymeric isocyanates, tse tsamaisoang ke li-catalyst tse loketseng le li-additives. Mefuta e fapaneng ea li-diisocyanate le li-polyols tse fumanehang li thusa bahlahisi ho theha mefuta e mengata ea thepa e lumellanang le lits'ebetso tse ikhethileng, ho etsa hore polyurethanes e be karolo ea liindasteri tse ngata.

Li-polyurethanes li fumaneha hohle bophelong ba sejoale-joale, li fumaneha lihlahisoa tse fapaneng ho tloha ho materase le libethe ho ea ho lisebelisoa tsa ho kenya letsoho, liphahlo tse metsi le lipente. Li boetse li sebelisoa ho li-elastomer tse tšoarellang nako e telele, tse kang mabili a blade, lintho tsa ho bapala tsa foam tse bonolo le likhoele tse rekerehang. Boteng ba bona bo atileng bo totobatsa bohlokoa ba bona ho ntlafatseng ts'ebetso ea sehlahisoa le boiketlo ba bareki.

Khemistri e ka morao ho tlhahiso ea polyurethane e kenyelletsa lisebelisoa tse peli tsa bohlokoa: methylene diphenyl diisocyanate (MDI) le toluene diisocyanate (TDI). Metsoako ena e sebetsana le metsi tikolohong ho etsa polyureas e tiileng ea inert, e bonts'a ho feto-fetoha le maemo a k'hemistri ea polyurethane.

Seboka sa 2024 Polyurethanes Technical Seboka se tla ba le mananeo a mangata a reretsoeng ho ruta ba tlileng kopanong ka tsoelo-pele ea morao-rao lebaleng. Litsebi li tla tšohla mekhoa e hlahang, lisebelisoa tse ncha, le bokamoso ba theknoloji ea polyurethane, e fanang ka lintlha tsa bohlokoa bakeng sa litsebi 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 ho nts'etsopele le ho sebelisoa ha thepa ea polyurethane.
