I-Atlanta, GA – Ukususela nge-30 kaSeptemba ukuya kwi-2 ka-Okthobha, i-Omni Hotel eCentennial Park iza kubamba iNkomfa yoBugcisa yePolyurethanes ka-2024, idibanisa iingcali eziphambili kunye neengcali ezivela kushishino lwe-polyurethane kwihlabathi liphela. Iququzelelwe yi-American Chemistry Council's Center for the Polyurethanes Industry (CPI), le ngqungquthela ijolise ekuboneleleni ngeqonga leeseshoni zemfundo kunye nokubonisa izinto ezintsha zamva nje kwikhemistri ye-polyurethane.

Iipolyurethanes zithathwa njengenye yezinto zeplastiki ezinokusetyenziswa ngeendlela ezahlukeneyo ezikhoyo namhlanje. Iimpawu zazo ezikhethekileyo zeekhemikhali zivumela ukuba zilungiselelwe uluhlu olubanzi lwezicelo, zisombulule imingeni enzima kwaye zibunjwe zibe ziimo ezahlukeneyo. Oku kuguquguquka kuphucula zombini iimveliso zoshishino kunye nabathengi, kongeza intuthuzelo, ubushushu, kunye nokulula kubomi bemihla ngemihla.

Ukuveliswa kwee-polyurethanes kubandakanya ukusabela kweekhemikhali phakathi kwee-polyols—utywala obunamaqela e-hydroxyl angaphezu kwamabini asebenzayo—kunye nee-diisocyanates okanye ii-isocyanates ze-polymeric, eziququzelelwa zii-catalysts ezifanelekileyo kunye nezongezo. Ukwahlukahluka kwee-diisocyanates kunye nee-polyols ezikhoyo kwenza abavelisi bakwazi ukwenza uluhlu olubanzi lwezinto ezilungiselelwe usetyenziso oluthile, okwenza ii-polyurethanes zibe yinxalenye yamashishini amaninzi.

Iipolyurethanes zifumaneka kakhulu kubomi banamhlanje, zifumaneka kwiimveliso ezahlukeneyo ukusuka kumatrasi nakwiisofa ukuya kwizinto zokukhusela, izinto zokwambathisa ulwelo, kunye neepeyinti. Zikwasetyenziswa kwii-elastomers ezihlala ixesha elide, ezifana namavili e-roller blade, izinto zokudlala ze-foam ezithambileyo neziguquguqukayo, kunye neefayibha ze-elastic. Ubukho bazo obubanzi bugxininisa ukubaluleka kwazo ekuphuculeni ukusebenza kwemveliso kunye nentuthuzelo yabathengi.

Ikhemistri engasemva kwemveliso ye-polyurethane ibandakanya ikakhulu izinto ezimbini ezibalulekileyo: i-methylene diphenyl diisocyanate (MDI) kunye ne-toluene diisocyanate (TDI). Ezi khompawundi zisabela namanzi kwindalo esingqongileyo ukuze zenze i-polyurea eqinileyo, ebonisa ukuguquguquka kunye nokuziqhelanisa kwekhemistri ye-polyurethane.

INkomfa yoBugcisa yePolyurethanes ka-2024 iza kuba neeseshoni ezahlukeneyo ezenzelwe ukufundisa abo babekhona ngenkqubela phambili yamva nje kweli candelo. Iingcali ziza kuxoxa ngeendlela ezintsha, usetyenziso olutsha, kunye nekamva lobuchwepheshe be-polyurethane, zibonelela ngolwazi oluxabisekileyo kwiingcali zoshishino.

Njengoko inkomfa isondela, abathathi-nxaxheba bayakhuthazwa ukuba badibane noontanga babo, babelane ngolwazi, baze bahlole amathuba amatsha kwicandelo le-polyurethane. Esi siganeko sithembisa ukuba yindibano ebalulekileyo kwabo babandakanyekayo ekuphuhlisweni nasekusetyenzisweni kwezinto ze-polyurethane.
