Atlanta, GA – Txij lub Cuaj Hlis 30 txog rau Lub Kaum Hli 2, Omni Hotel ntawm Centennial Park yuav tuav lub Rooj Sab Laj Txog Kev Siv Polyurethanes Xyoo 2024, uas coj cov kws tshaj lij thiab cov kws tshaj lij los ntawm kev lag luam polyurethane thoob ntiaj teb los sib sau ua ke. Lub Rooj Sab Laj no tau teeb tsa los ntawm American Chemistry Council's Center for the Polyurethanes Industry (CPI), lub hom phiaj yog muab lub platform rau kev kawm thiab qhia txog cov kev hloov tshiab tshiab hauv kev siv polyurethane.

Cov polyurethanes raug lees paub tias yog ib qho ntawm cov khoom siv yas uas muaj ntau yam siv tau niaj hnub no. Lawv cov yam ntxwv tshuaj lom neeg tshwj xeeb ua rau lawv tuaj yeem tsim rau ntau yam kev siv, daws cov teeb meem nyuaj thiab ua rau ntau yam duab. Qhov kev hloov pauv no ua rau cov khoom lag luam thiab cov khoom siv rau cov neeg siv khoom zoo dua, ntxiv kev nplij siab, sov so, thiab yooj yim rau lub neej txhua hnub.

Kev tsim cov polyurethanes muaj kev sib xyaw ua ke ntawm cov tshuaj polyols—cawv nrog ntau dua ob pawg hydroxyl reactive—thiab diisocyanates lossis polymeric isocyanates, uas tau ua los ntawm cov catalysts thiab cov khoom ntxiv. Qhov sib txawv ntawm cov diisocyanates thiab polyols muaj ua rau cov chaw tsim khoom tsim ntau yam khoom siv rau cov ntawv thov tshwj xeeb, ua rau polyurethanes tseem ceeb rau ntau yam kev lag luam.

Cov polyurethanes muaj nyob txhua qhov chaw hauv lub neej niaj hnub no, pom muaj ntau yam khoom xws li cov txaj pw thiab cov rooj zaum mus rau cov ntaub ntawv rwb thaiv tsev, cov tshuaj pleev xim, thiab cov xim. Lawv kuj siv rau hauv cov elastomers ruaj khov, xws li cov log tsheb dov, cov khoom ua si ua npuas ncauj mos mos, thiab cov fibers elastic. Lawv qhov muaj dav dav qhia txog lawv qhov tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm cov khoom thiab kev nplij siab ntawm cov neeg siv khoom.

Cov tshuaj lom neeg tom qab kev tsim cov polyurethane feem ntau yog siv ob yam khoom tseem ceeb: methylene diphenyl diisocyanate (MDI) thiab toluene diisocyanate (TDI). Cov tshuaj no ua rau dej hauv ib puag ncig sib xyaw ua ke los ua cov khoom siv polyurea khov kho, qhia txog kev ua tau ntau yam thiab kev hloov pauv tau ntawm cov tshuaj polyurethane.

Lub Rooj Sab Laj Txog Kev Siv Polyurethanes Xyoo 2024 yuav muaj ntau yam kev sib tham uas tsim los qhia cov neeg tuaj koom txog kev nce qib tshiab hauv daim teb no. Cov kws tshaj lij yuav tham txog cov qauv tshiab, cov kev siv tshiab, thiab yav tom ntej ntawm cov thev naus laus zis polyurethane, muab cov kev nkag siab zoo rau cov kws tshaj lij hauv kev lag luam.

Thaum lub rooj sib tham los txog, cov neeg koom nrog raug txhawb kom koom nrog cov phooj ywg, sib qhia kev paub, thiab tshawb nrhiav cov cib fim tshiab hauv kev lag luam polyurethane. Qhov kev tshwm sim no cog lus tias yuav yog ib qho kev sib sau ua ke tseem ceeb rau cov neeg koom nrog hauv kev tsim thiab kev siv cov ntaub ntawv polyurethane.
