I-Atlanta, GA - Kusukela ngo-September 30 kuya ku-Okthoba 2, i-Omni Hotel e-Centennial Park izosingatha iNgqungquthela Yobuchwepheshe ye-Polyurethanes ye-2024, ihlanganisa ndawonye ochwepheshe abaholayo nochwepheshe abavela embonini ye-polyurethane emhlabeni wonke. Ihlelwe i-American Chemistry Council's Center for the Polyurethanes Industry (CPI), le ngqungquthela ihlose ukuhlinzeka ngenkundla yezikhathi zemfundo futhi ibonise izinto ezintsha zakamuva kukhemikhali ye-polyurethane.

Ama-polyurethanes abonwa njengenye yezinto zepulasitiki eziguquguqukayo ezitholakala namuhla. Izakhiwo zabo zamakhemikhali eziyingqayizivele zivumela ukuba zivumelane nezinhlobonhlobo zezinhlelo zokusebenza, ukuxazulula izinselele eziyinkimbinkimbi futhi zibunjwe zibe izimo ezihlukahlukene. Lokhu kuzivumelanisa nezimo kuthuthukisa kokubili imikhiqizo yezimboni nezabathengi, kwengeze ukunethezeka, ukufudumala, kanye nokunethezeka empilweni yansuku zonke.

Ukukhiqizwa kwe-polyurethanes kuhilela ukusabela kwamakhemikhali phakathi kwe-polyols-utshwala obunamaqembu angaphezu kwamabili e-hydroxyl asebenzayo-kanye nama-disocyanate noma ama-polymeric isocyanates, aqhutshwa ama-catalyst afanelekile nezithasiselo. Izinhlobonhlobo zama-disocyanate nama-polyols atholakalayo zenza abakhiqizi bakwazi ukwakha i-spectrum ebanzi yezinto zokwakha ezifanelana nezinhlelo ezithile zokusebenza, okwenza ama-polyurethanes ahlanganiswe nezimboni eziningi.

Ama-polyurethanes atholakala yonke indawo empilweni yesimanje, atholakala emikhiqizweni eyahlukene kusukela komatilasi namasofa kuya ezintweni zokufaka izinto ezifakwa ngaphakathi, okokunamathela okuwuketshezi, nopende. Abuye asetshenziswe kuma-elastomer ahlala isikhathi eside, njengamasondo e-roller blade, amathoyizi egwebu athambile athambile, nemicu enwebekayo. Ukuba khona kwazo okusabalele kugcizelela ukubaluleka kwazo ekuthuthukiseni ukusebenza komkhiqizo nokunethezeka kwabathengi.

Ikhemikhali ngemuva kokukhiqizwa kwe-polyurethane ngokuyinhloko ihilela izinto ezimbili ezibalulekile: i-methylene diphenyl diisocyanate (MDI) ne-toluene diisocyanate (TDI). Lezi zinhlanganisela zibhekana namanzi endaweni ukuze zenze ama-inert polyureas aqinile, abonisa ukuguquguquka nokuguquguquka kwekhemikhali ye-polyurethane.

I-2024 Polyurethanes Technical Conference izoba nohlu lwezikhathi eziklanyelwe ukufundisa abahambele umcimbi ngentuthuko yakamuva kulo mkhakha. Ochwepheshe bazoxoxa ngezitayela ezivelayo, izinhlelo zokusebenza ezintsha, kanye nekusasa lobuchwepheshe be-polyurethane, ehlinzeka ngemininingwane ebalulekile yochwepheshe bemboni.

Njengoba ingqungquthela isondela, ababambiqhaza bayakhuthazwa ukuthi bahlanganyele nontanga, ukwabelana ngolwazi, futhi bahlole amathuba amasha ngaphakathi komkhakha we-polyurethane. Lo mcimbi uthembisa ukuthi uzoba umbuthano obalulekile walabo ababambe iqhaza ekuthuthukisweni nasekusetshenzisweni kwezinto ze-polyurethane.
