I-Atlanta, Ga - Ukususela nge-30 kaSeptemba ukuya kwi-2 ka-Okthobha, ihotele yase-Omni eCalncialial Park izakusinga i-2024 Polyreurthanes bobuchwephesha, ingenisa iingcali ezikhokelayo kwicandelo lePolysurethane kwihlabathi liphela. Ihlelwe liziko leBhunga laseMelika le-chemistry kwiShishini lePolyurrethanes (i-CPI), iNkomfa ijolise ekunikezeleni iqonga leeseshoni zemfundo kwaye ibonisa intsha entsha kwi-Polyurethane.

I-Polyurrethanes yamkelwe njengenye yezona zixhobo zeplastiki ezikhoyo ezikhoyo namhlanje. Iipropathi zabo ezizodwa zibavumela ukuba zilungiswe uluhlu olubanzi lwezicelo, zisombulula iingxaki ezintsonkothileyo kunye nokubunjwa kwemilo eyahlukeneyo. Olu tshintsho luphucula iimveliso zozimizo kunye nabathengi, ukongeza intuthuzelo, ubushushu, kunye nokulula kubomi bemihla ngemihla.

Ukuveliswa kweepoliurethanes kubandakanya indlela yokuphendula yemichiza phakathi kwe-Polyols -s enamaqela angaphezulu kwamaqela amabini asebenzayo-kunye ne-disoclocy okanye i-polymeates okanye i-polymeric catavests kunye nezongezo. I-Iyantlokwankulu ye-Diisoclostanates kunye nePolyls inika abavelisi ukuba benze izinto ezibanzi zezinto ezilungiselelwe izicelo ezithile, zenza i-polysurethanes ezahlukeneyo kumashishini amaninzi.

I-Polyurrethanes zizinto zobomi bale mihla, ezifumaneka kwiintlobo ezahlukeneyo zeemveliso ezisusela kwimatrasi kunye nezigculelo kwizinto zokufakwa, iingubo ezingamanzi, kunye neepeyinti. Zikwasetyenziswa nakwi-elastomers eyomeleleyo, efana ne-rolleller blade amavili, iithoyi ezithambileyo ze-foys, kunye neentsinga ze-elastic. Ubukho babo obubanzi bugxininisa ukubaluleka kwabo ekuphuculeni intsebenzo yemveliso kunye nentuthuzelo yabathengi.

I-chemistry emva kwemveliso yePolyrerthane ikakhulu ibandakanya izinto ezimbini eziphambili: i-methylene dighenyl diisocyanate (MDI) kunye ne-toluene disocyastate (TDI). Ezi zinto zimiselweyo ngamanzi kwindalo esingqongileyo ukwenza i-inter polyreares, ukubonisa ukungahambi kakuhle kunye nokulungelelanisa kwePolylidthane Chemistry.

Inkomfa yobugcisa ye-2024 Polyrerthanes iya kubonisa uluhlu lweeseshoni ezenzelwe ukufundisa ababezibezisele kwinkqubela phambili yamva nje ebaleni. Iingcali ziya kuthetha ngeendlela ezivelayo, izicelo ezinobuchule, kunye nekamva letekhnoloji yePolyurethane, zibonelela ngengqondo ebalulekileyo yeengcali zeshishini.

Njengoko inkomfa yenkomfa, abathathi-nxaxheba bayakhuthazwa ukuba bazibandakanye noontanga, babelana ngolwazi, kwaye baphonononge amathuba amatsha kwicandelo lePolyurrethane. Lo msitho uthembisa ukuba yindibano ebalulekileyo kwabo babandakanyekayo kuphuhliso kunye nokusetyenziswa kwezixhobo zePolyurethane.
