Mndandanda Wapadera wa Mphotho ya Polyurethane Innovation ya 2025 Walengezedwa, Ukadaulo Wozikidwa pa Bio Wakhala Pamalo Ofunika Kwambiri

Posachedwapa, Center for Polyurethane Industry (CPI) pansi pa American Chemistry Council (ACC) yalengeza mwalamulo mndandanda wa omwe adzapambane mphoto ya Polyurethane Innovation Award ya 2025. Monga chizindikiro chodziwika bwino pamakampani opanga polyurethane padziko lonse lapansi, mphothoyi yakhala ikuperekedwa kwa nthawi yayitali pozindikira kupita patsogolo kwakukulu pakusamalira chilengedwe, kugwira ntchito bwino, komanso magwiridwe antchito ambiri a zinthu za polyurethane. Mndandanda wa chaka chino wakopa chidwi cha anthu ambiri, ndi matekinoloje awiri apamwamba omwe akuyang'ana kwambiri pakupanga zinthu zatsopano zochokera ku zinthu zachilengedwe komanso kupanga zinthu zosamalira chilengedwe zomwe zapeza malo. Kuphatikizidwa kwawo sikungowonetsa kudzipereka kosalekeza kwa makampaniwa pakusunga chilengedwe komanso kumawonetsa kuti ukadaulo wozikidwa pa zinthu zachilengedwe wayamba kukhala chinthu chofunikira kwambiri pakupanga zinthu zatsopano komanso kukweza zinthu m'gawo la polyurethane.

Zipangizo za polyurethane, zodziwika bwino chifukwa cha ntchito yawo yabwino kwambiri, zimagwiritsidwa ntchito kwambiri m'mafakitale ofunikira monga zomangamanga, kupanga magalimoto, kulongedza, ndi chisamaliro chaumoyo. Komabe, njira zopangira zachikhalidwe zakhala zikugwiritsa ntchito mafuta, ndipo zinthu zomaliza nthawi zambiri siziwonongeka, zomwe zimaika makampaniwa pansi pa zovuta ziwiri zokhudzana ndi chilengedwe komanso zoletsa chuma. Poganizira zolinga zapadziko lonse lapansi zosagwirizana ndi mpweya woipa, kulimbitsa malamulo okhudza chilengedwe, komanso kufunikira kwa ogula zinthu zobiriwira, kupanga ukadaulo wa polyurethane wosaipitsa mpweya, wongowonjezedwanso, komanso wobwezerezedwanso kwakhala njira yosapeŵeka yosinthira mafakitale. Maukadaulo awiriwa omwe asankhidwa ndi omwe akwaniritsa izi, akupereka mayankho othandiza pakusintha kobiriwira kwa makampani a polyurethane.

Pakati pawo, Soleic® yopangidwa ndi Algenesis Labs yatchuka kwambiri chifukwa cha kapangidwe kake ka 100% ka zinthu zachilengedwe komanso magwiridwe antchito abwino kwambiri pa chilengedwe. Monga polyester polyol yoyera kwambiri, Soleic® yapeza satifiketi pansi pa US Department of Agriculture (USDA) BioPreferred® Program—kuzindikira kolimba komwe kumatsimikizira kuti ikutsatira miyezo yapadziko lonse lapansi ya zinthu zachilengedwe, kulimbitsa udindo wake ngati chinthu chobwezerezedwanso komanso chosamalira chilengedwe. Mosiyana ndi polyester polyols wamba wochokera ku chakudya chochokera ku mafuta, luso lalikulu la Soleic® lili mu kupeza kwake zinthu zopangira mokhazikika: imagwiritsa ntchito algae ndi mbewu zopanda chakudya ngati zopangira zazikulu. Algae, chuma chachilengedwe chokhala ndi nthawi yochepa kwambiri yokulira komanso mphamvu yobereka, sikuti imangofuna malo olimapo (kupewa mpikisano ndi kupanga chakudya) komanso imatenga mpweya wambiri wa carbon dioxide panthawi yokukula, zomwe zimathandiza kuchepetsa mpweya wa carbon. Kuphatikizidwa kwa mbewu zopanda chakudya monga udzu ndi hemp kumawonjezeranso magwiridwe antchito obwezeretsanso zinthu pamene kumachepetsa kutulutsa zinyalala zaulimi.

Chofunika kwambiri, zinthu zomaliza zopangidwa ndi Soleic® zimawononga bwino kwambiri. M'malo achilengedwe (monga dothi, madzi a m'nyanja, kapena malo opangira manyowa m'mafakitale), zinthuzi zimatha kuonongeka kwathunthu ndi tizilombo toyambitsa matenda kukhala madzi ndi carbon dioxide popanda kusiya zotsalira zilizonse zovulaza, zomwe kwenikweni zimathetsa vuto la kuipitsidwa kwa microplastic komwe kumachitika chifukwa cha zinthu zachikhalidwe za polyurethane zomwe zatayidwa. Pakadali pano, Soleic® yagwiritsidwa ntchito kwambiri mu thovu losinthasintha, zokutira, zomatira, zida zopakira, ndi zina. Sikuti imangopeza kupita patsogolo pa magwiridwe antchito achilengedwe komanso imakwaniritsa miyezo yotsogola m'mafakitale mu zizindikiro zazikulu monga mawonekedwe a makina ndi kukana kutentha, ndikuzindikira "kupambana konse" pakati pa kusamala chilengedwe ndi magwiridwe antchito. Izi zimapatsa mabizinesi apansi thandizo lalikulu la zinthu zopangira zinthu zobiriwira.

Ukadaulo wina womwe wasankhidwa ndi HandiFoam® E84 womwe uli ndi zigawo ziwiri zopopera polyurethane thovu zomwe zayambitsidwa ndi ICP. Chogwiritsidwa ntchito paukadaulo wa Hydrofluoroolefin (HFO) wa m'badwo watsopano, chida ichi chimayang'ana kwambiri pakukweza mphamvu zogwiritsira ntchito bwino komanso kukonza magwiridwe antchito achilengedwe, zomwe zapangitsa kuti chipeze UL GREENGUARD Gold Certification—kudziwika bwino kwa mpweya wake wotsika wa Volatile Organic Compound (VOC). Chitsimikizochi chikutsimikizira kuti HandiFoam® E84 siiwononga mpweya wabwino wamkati ikagwiritsidwa ntchito, zomwe zimapangitsa kuti ikhale chinthu chapamwamba kwambiri chomwe chimagwirizanitsa chitetezo cha chilengedwe ndi thanzi.

Ponena za luso lamakono, chotsukira cha HFO chomwe chimagwiritsidwa ntchito mu HandiFoam® E84 chimagwira ntchito ngati njira ina yotetezera chilengedwe m'malo mwa chotsukira cha Hydrofluorocarbon (HFC) chachikhalidwe. Poyerekeza ndi ma HFC, ma HFO ali ndi mphamvu yochepa kwambiri ya Global Warming Potential (GWP), yomwe imachepetsa kwambiri mpweya woipa womwe umatuluka komanso kuchepetsa kuwonongeka kwa ozone layer. Izi zikugwirizana ndi mfundo zachilengedwe padziko lonse lapansi zomwe zimalimbikitsa zofunikira za carbon yochepa kwa mafiriji ndi zotsukira. Monga thovu la polyurethane lopopera la magawo awiri, HandiFoam® E84 ili ndi mphamvu zabwino kwambiri zotetezera kutentha komanso zotsekera, makamaka zabwino kwambiri mu gawo la mphamvu zogwirira ntchito m'nyumba. Ikagwiritsidwa ntchito pamakoma akunja, mipata ya zitseko/mawindo, ndi madenga a nyumba, imapanga chotsukira chokhazikika, cholimba chomwe chimachepetsa kwambiri kusamutsa kutentha pakati pa malo amkati ndi akunja, kuchepetsa kugwiritsa ntchito mphamvu kwa makina oziziritsira mpweya ndi kutentha. Malinga ndi kuyerekezera, nyumba zomwe zimagwiritsa ntchito HandiFoam® E84 zimatha kuchepetsa kugwiritsa ntchito mphamvu ndi 20%-30%, osati kungopulumutsa ogwiritsa ntchito pamtengo wamagetsi komanso kuthandizira makampani omanga kuti akwaniritse zolinga zochepetsera mpweya woipa. Kuphatikiza apo, chinthuchi chili ndi ubwino monga kumangidwa kosavuta, kuchira mwachangu, komanso kumamatira mwamphamvu, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito m'malo osiyanasiyana kuphatikizapo nyumba zogona, nyumba zamalonda, malo osungiramo zinthu zozizira, ndi zida zamafakitale, motero chimakhala ndi mwayi wogwiritsidwa ntchito pamsika waukulu.

Kulengezedwa kwa mndandanda wa mphoto ya Polyurethane Innovation Award ya 2025 sikuti kumangotsimikizira zatsopano zaukadaulo za Algenesis Labs ndi ICP komanso kukuwonetsa momwe makampani opanga polyurethane akupitira patsogolo padziko lonse lapansi—ukadaulo wopangidwa ndi zinthu zachilengedwe, kupanga zinthu zopanda mpweya woipa, ndi kugwiritsa ntchito zinthu zozungulira kwakhala mawu ofunikira kwambiri pakupanga zinthu zatsopano. Pakati pa mavuto azachilengedwe omwe akuchulukirachulukira, makampani opanga polyurethane amatha kupambana mpikisano pongoyang'ana kwambiri pa kafukufuku ndi chitukuko chaukadaulo wokhazikika, pomwe akuthandizira kuteteza chilengedwe padziko lonse lapansi komanso kukwaniritsa zolinga za carbon neutral. M'tsogolomu, ndi kuchepetsa ndalama zopangira zinthu zachilengedwe komanso kupitilizabe kugwiritsa ntchito ukadaulo wa zachilengedwe, makampani opanga polyurethane akuyembekezeka kukwaniritsa kusintha kwakukulu kwachilengedwe, kupereka mayankho abwino kwambiri azinthu zachilengedwe, ogwira ntchito bwino, komanso okhazikika m'magawo osiyanasiyana ogwiritsira ntchito.
