Atlanta, GA - Kuyambira pa Seputembara 30 mpaka Okutobala pa Centernnial Park idzayambitsa maphunziro a 2024 a Polyiretane, kubweretsa pamodzi ndi akatswiri otsogola ndi akatswiri ogulitsa pa polyuretethane padziko lonse lapansi. Wokonzedwa ndi likulu la American Courtcil County la Countl Chemistc of the Polyurethathanes (CPI), msonkhano umafuna kupereka nsanja zamaphunziro ndikuwonetsa zatsopano mu ma mulmurethane chemistry.

Ma polsurethanes amadziwika kuti ndi amodzi mwazinthu zapulasitiki zosintha kwambiri zomwe zilipo masiku ano. Mankhwala awo apadera amawathandiza kuti azigwiritsa ntchito mapulogalamu osiyanasiyana, kuthetsa zovuta zovuta ndikupangidwa mu mawonekedwe osiyanasiyana. Kusinthasintha kumeneku kumawonjezera zinthu zonse ziwiri za mafakitale ndi ogula, kuwonjezera chitonthozo, kutentha, komanso kuphweka kwa moyo watsiku ndi tsiku.

Kupanga kwa polyuretethas kumaphatikizapo kusiyanasiyana kwa ma polylols-mowa wokhala ndi magulu ochulukirapo awiri a hydroxyl. Kusiyanasiyana kwa diisoctanesi ndi ma polylols kumathandizira opanga kuti apange mawonekedwe owoneka bwino a zinthu zomwe zimagwirizana ndi mapulogalamu, ndikupanga polyirethanes ofanana kwa mafakitale ambiri.

Ma polsurethanes ndi osapatsa zinthu amakono, amapezeka m'malo osiyanasiyana kuyambira matiresi ndi mipando mpaka zotupa, zokutira zamadzi, ndi zotupa. Amagwiritsidwanso ntchito mu elastomers olimba, monga mawilo ozungulira a Ruller, zoseweretsa zosinthika zosinthika, ndi ulusi wonyezimira. Kukhalapo kwawo kumatsimikizira kufunikira kwawo kulimbikitsa ntchito zamayendedwe ndi ogula.

Micristry kumbuyo kwa polyirethane imakhudzanso zida ziwiri: methylene Litsisnyl Diisocyanate (MDI) ndi Toliene Diisocyanga (TDI). Izi zimakhudzana ndi madzi m'malo okhala kuti apange ma coul okhazikika, kuwonetsa kusinthasintha kwa ma mulyurethane chemistry.

Msonkhano waukadaulo wa 2024 udzakhala ndi magawo osiyanasiyana opangidwa kuti aphunzitse anthu opezeka pathanthwe. Akatswiri adzakambirana zomwe zikuchitika, kugwiritsa ntchito njira zatsopano, komanso tsogolo laukadaulo wa poureurethan, ndikupereka magwiridwe antchito a akatswiri ogwiritsa ntchito.

Monga momwe msonkhano umayendera, ophunzira akulimbikitsidwa kuti azichita nawo anzawo, kugawana nzeru, ndikufufuza mipata yatsopano. Mwambowu umalonjeza kuti ndi kusonkhanitsa kothandiza kwa iwo omwe akuchita nawo chitukuko ndi kugwiritsa ntchito zida za pourerethane.

Kuti mumve zambiri za Countl Council Council ndi msonkhano womwe ukubwera, pitani www.americanchem.com.
