I-Atlanta, GA – Kusukela mhla zingama-30 kuMandulo kuya kumhla zi-2 kuMfumfu, i-Omni Hotel eCentennial Park izosingatha iNgqungquthela Yobuchwepheshe be-Polyurethanes ka-2024, ihlanganisa ochwepheshe abaphambili kanye nochwepheshe abavela embonini ye-polyurethane emhlabeni jikelele. Ihlelwe yi-American Chemistry Council's Center for the Polyurethanes Industry (CPI), le ngqungquthela ihlose ukuhlinzeka ngeplatifomu yezikhathi zemfundo nokukhombisa izinto ezintsha zakamuva kumakhemikhali e-polyurethane.

Ama-polyurethane aqashelwa njengenye yezinto zepulasitiki eziguquguqukayo kakhulu ezitholakalayo namuhla. Izakhiwo zawo zamakhemikhali ezihlukile zivumela ukuthi zilungiselelwe izinhlelo zokusebenza ezahlukahlukene, zixazulule izinselele eziyinkimbinkimbi futhi zibunjwe zibe yizimo ezahlukahlukene. Lokhu kuvumelana nezimo kuthuthukisa kokubili imikhiqizo yezimboni kanye neyabathengi, kwengeza induduzo, ukufudumala, kanye nokulula empilweni yansuku zonke.

Ukukhiqizwa kwama-polyurethane kuhilela ukusabela kwamakhemikhali phakathi kwama-polyol—utshwala obunamaqembu angaphezu kwamabili e-hydroxyl asebenzayo—kanye nama-diisocyanates noma ama-isocyanates e-polymeric, aqhutshwa yi-catalysts kanye nezithasiselo ezifanele. Ukuhlukahluka kwama-diisocyanates nama-polyol atholakalayo kwenza abakhiqizi bakwazi ukudala ububanzi bezinto ezilungiselelwe izinhlelo zokusebenza ezithile, okwenza ama-polyurethane abe yingxenye yezimboni eziningi.

Ama-polyurethane atholakala yonke indawo empilweni yanamuhla, atholakala emikhiqizweni eyahlukahlukene kusukela kuma-mattress nama-sofa kuya ezintweni zokuvikela ukushisa, izinto zokumboza ngoketshezi, kanye nopende. Asetshenziswa futhi kuma-elastomer aqinile, njengamasondo e-roller blade, amathoyizi e-foam athambile aguquguqukayo, kanye nemicu ye-elastic. Ukuba khona kwawo kabanzi kugcizelela ukubaluleka kwawo ekuthuthukiseni ukusebenza komkhiqizo kanye nenduduzo yabathengi.

Ikhemikhali engemuva kokukhiqizwa kwe-polyurethane ihilela ngokuyinhloko izinto ezimbili ezibalulekile: i-methylene diphenyl diisocyanate (MDI) kanye ne-toluene diisocyanate (TDI). Lawa ma-compound asabela namanzi endaweni ezungezile ukuze akhe ama-polyurea aqinile angangeni, okubonisa ukuguquguquka kanye nokuzivumelanisa nezimo kwe-polyurethane chemistry.

Ingqungquthela Yobuchwepheshe be-Polyurethanes ka-2024 izoba nezingxoxo ezahlukahlukene ezenzelwe ukufundisa ababekhona ngentuthuko yakamuva kulo mkhakha. Ochwepheshe bazoxoxa ngezitayela ezintsha, izinhlelo zokusebenza ezintsha, kanye nekusasa lobuchwepheshe be-polyurethane, banikeze ulwazi olubalulekile kochwepheshe bemboni.

Njengoba ingqungquthela isondela, abahlanganyeli bakhuthazwa ukuba bahlanganyele nontanga, babelane ngolwazi, futhi bahlole amathuba amasha emkhakheni we-polyurethane. Lo mcimbi uthembisa ukuba umhlangano obalulekile kulabo abahilelekile ekuthuthukisweni nasekusetshenzisweni kwezinto ze-polyurethane.
