I-Atlanta, GA - Ukususela ngoSeptemba 30 ukuya ku-Oktobha 2, i-Omni Hotel kwi-Centennial Park iya kubamba iNkomfa yezobuGcisa ye-Polyurethanes ye-2024, idibanisa iingcali ezikhokelayo kunye neengcali ezivela kwishishini le-polyurethane emhlabeni jikelele. Iququzelelwe yi-American Chemistry Council's Centre ye-Polyurethanes Industry (CPI), inkomfa ijolise ukubonelela ngeqonga leeseshoni zemfundo kunye nokubonisa izinto ezintsha zamva nje kwi-polyurethane chemistry.

Iipolyurethanes zibonwa njengenye yezona zinto ziguquguqukayo zeplastiki ezikhoyo namhlanje. Iimpawu zabo zeekhemikhali ezikhethekileyo zivumela ukuba zilungelelaniswe uluhlu olubanzi lwezicelo, ukuxazulula imingeni enzima kunye nokubunjwa kwiimo ezahlukeneyo. Oku kuziqhelanisa kuphucula zombini iimveliso zamashishini kunye nabathengi, zongeza intuthuzelo, ukufudumala, kunye nokulula kubomi bemihla ngemihla.

Ukuveliswa kwe-polyurethanes kubandakanya ukuphendulwa kweekhemikhali phakathi kwe-polyols-alcohols kunye namaqela angaphezu kwamabini asebenzayo e-hydroxyl-kunye ne-disocyanates okanye i-polymeric isocyanates, eququzelelwa yi-catalysts efanelekileyo kunye nezongezo. Ukwahluka kwee-diisocyanates ezikhoyo kunye ne-polyols zenza abavelisi benze uluhlu olubanzi lwemathiriyeli elungiselelwe usetyenziso oluthile, ukwenza i-polyurethanes idityaniswe kumashishini amaninzi.

Iipolyurethanes zikho kuyo yonke indawo kubomi banamhlanje, zifumaneka kwiimveliso ezahlukeneyo ukusuka kumatrasi kunye neebhedi ukuya kwizinto zokugquma, iileyile zolwelo, kunye neepeyinti. Zikwasetyenziswa kwii-elastomers ezomeleleyo, njengamavili anencakuba eqengqelekayo, iithoyi ezithambileyo zogwebu ezithambileyo, kunye nemicu enwebekayo. Ubukho babo ngokubanzi bugxininisa ukubaluleka kwabo ekwandiseni ukusebenza kwemveliso kunye nokuthuthuzela kwabathengi.

I-chemistry emva kwemveliso ye-polyurethane ngokuyinhloko ibandakanya izinto ezimbini eziphambili: i-methylene diphenyl diisocyanate (MDI) kunye ne-toluene diisocyanate (TDI). Ezi khompawundi zisabelana namanzi kwimekobume ukuze zenze iipolyureas eziqinileyo, ezibonisa ukuguquguquka kunye nokuguquguquka kwe-polyurethane chemistry.

INkomfa yezobuGcisa yePolyurethanes ka-2024 iya kuba noluhlu lweeseshoni ezenzelwe ukufundisa abantu abaya kubakho ukuqhubela phambili kwintsimi. Iingcali ziya kuxoxa ngeendlela ezivelayo, izicelo ezintsha, kunye nekamva lobuchwepheshe be-polyurethane, ukubonelela ngolwazi olubalulekileyo kwiingcali zoshishino.

Njengoko inkomfa isondela, abathathi-nxaxheba bayakhuthazwa ukuba badibanise noontanga, babelane ngolwazi, kwaye bahlolisise amathuba amatsha ngaphakathi kwecandelo le-polyurethane. Esi siganeko sithembisa ukuba yindibano ebalulekileyo kwabo babandakanyekayo ekuphuhliseni nasekusetyenzisweni kwezinto ze-polyurethane.
