Atlanta, GA – Laga bilaabo Sebtembar 30 ilaa Oktoobar 2, Hudheelka Omni ee ku yaal Centennial Park ayaa martigelin doona Shirka Farsamada ee Polyurethanes 2024, kaas oo isu keenaya xirfadlayaal iyo khubaro hormuud ka ah warshadaha polyurethane adduunka oo dhan. Shirkan oo ay soo qabanqaabisay Xarunta Warshadaha Polyurethanes ee Golaha Kimistariga Mareykanka (CPI), ayaa ujeedadiisu tahay in la helo goob loogu talagalay kalfadhiyada waxbarashada iyo in lagu soo bandhigo hal-abuurkii ugu dambeeyay ee kiimikada polyurethane.

Polyurethanes waxaa loo aqoonsan yahay inay tahay mid ka mid ah agabka balaastikada ugu badan ee la heli karo maanta. Sifooyinka kiimikada ee gaarka ah waxay u oggolaanayaan in loo habeeyo adeegyo kala duwan, xallinta caqabadaha adag iyo in loo qaabeeyo qaabab kala duwan. La qabsigan wuxuu kor u qaadaa labadaba alaabada warshadaha iyo kuwa macaamiisha, isagoo ku daraya raaxo, diirimaad, iyo raaxo nolol maalmeedka.

Soo saarista polyurethanes waxay ku lug leedahay falgal kiimiko ah oo u dhexeeya polyols - aalkolo leh in ka badan laba kooxood oo hydroxyl ah oo falcelin leh - iyo diisocyanates ama isocyanates polymeric ah, oo ay fududeeyaan kataliyayaal iyo waxyaabo lagu daro oo ku habboon. Kala duwanaanshaha diisocyanates iyo polyols ee la heli karo waxay u suurtagelinaysaa soosaarayaasha inay abuuraan noocyo badan oo agab ah oo loogu talagalay codsiyada gaarka ah, taasoo ka dhigaysa polyurethanes mid muhiim u ah warshado badan.

Polyurethanes-ku waa kuwo aad ugu badan nolosha casriga ah, waxaana laga helaa noocyo kala duwan oo alaab ah oo u dhexeeya joodariyaasha iyo kuraasta ilaa agabka dahaarka, dahaarka dareeraha ah, iyo rinjiga. Waxaa sidoo kale loo isticmaalaa elastomer-yada waara, sida giraangiraha daabka rogidda, alaabta carruurtu ku ciyaarto ee jilicsan ee dabacsan, iyo fiilooyinka laastikada ah. Joogitaankooda baahsan wuxuu hoosta ka xariiqayaa muhiimadda ay u leeyihiin kor u qaadista waxqabadka badeecadaha iyo raaxada macaamiisha.

Kiimikada ka dambeysa soo saarista polyurethane waxay ugu horreyn ku lug leedahay laba walxood oo muhiim ah: methylene diphenyl diisocyanate (MDI) iyo toluene diisocyanate (TDI). Isku-dhafkan wuxuu la falgalaa biyaha deegaanka si uu u sameeyo polyureas adag oo aan firfircoonayn, taasoo muujinaysa kala-duwanaanta iyo la-qabsiga kiimikada polyurethane.

Shirka Farsamada ee Polyurethanes 2024 wuxuu soo bandhigi doonaa kalfadhiyo kala duwan oo loogu talagalay in lagu baro ka qaybgalayaasha horumarka ugu dambeeyay ee goobta. Khubaradu waxay ka wada hadli doonaan isbeddellada soo ifbaxaya, codsiyada cusub, iyo mustaqbalka tignoolajiyada polyurethane, iyagoo siinaya aragtiyo qiimo leh xirfadlayaasha warshadaha.

Marka shirku soo dhawaado, ka qaybgalayaasha waxaa lagu dhiirigelinayaa inay la falgalaan asxaabta, wadaagaan aqoonta, iyo inay sahamiyaan fursado cusub oo ka jira qaybta polyurethane. Dhacdadani waxay ballan qaadaysaa inay noqon doonto kulan muhiim ah oo loogu talagalay kuwa ku lug leh horumarinta iyo adeegsiga agabka polyurethane.
