Kutshanje, iZiko leMicimbi yePolyurethane (CPI) phantsi kweBhunga leKhemistri laseMelika (i-ACC) lityhile ngokusesikweni uluhlu olufutshane lweMbasa yePolyurethane Innovation ka-2025. Njengendlela edumileyo kwishishini le-polyurethane lehlabathi, eli bhaso kudala linikezelwe ekuqapheleni inkqubela phambili ebalulekileyo ekuthandeni okusingqongileyo, ukusebenza kakuhle, kunye nokusebenza kwezinto ezininzi ze-polyurethane. Uluhlu olufutshane lwalo nyaka lufumene ingqalelo ebanzi, kunye neetekhnoloji ezimbini eziphambili ezigxile kwimveliso entsha esekwe kwi-bio kunye neefomyula ezinobuhlobo nendalo ezifumana indawo. Ukubandakanywa kwazo akubonisi nje kuphela ukuzinikela okungagungqiyo kweshishini ekuzinzeni kodwa kukwabonisa ukuba itekhnoloji esekwe kwi-bio ivele njengomqhubi ophambili wokuvelisa izinto ezintsha kunye nokuphucula kwicandelo le-polyurethane.
Izinto zePolyurethane, ezidumileyo ngokusebenza kwazo okugqwesileyo, zisetyenziswa kakhulu kumashishini abalulekileyo afana nokwakha, ukwenziwa kweemoto, ukupakisha, kunye nokhathalelo lwempilo. Nangona kunjalo, iinkqubo zemveli zemveliso bezixhomekeke kumafutha efosili ixesha elide, kwaye iimveliso zokugqibela zihlala zingaboli, nto leyo ebeka ishishini phantsi koxinzelelo oluphindwe kabini lwenkxalabo yokusingqongileyo kunye nemida yezixhobo. Ngokuchasene nemvelaphi yeenjongo zokungathathi cala kwekhabhoni kwihlabathi liphela, ukuqinisa imithetho yokusingqongileyo, kunye nokukhula kwemfuno yabathengi yeemveliso eziluhlaza, ukuphuhlisa ubuchwepheshe be-polyurethane obungcolisekileyo, obuvuselelekayo, kunye nobuphinda busetyenziswe bube yindlela engenakuphepheka yokutshintsha kwemizi-mveliso. Ezi teknoloji zimbini zidweliswe ngentla zimi njengeempumelelo ezimele le ndlela, zibonelela ngezisombululo ezisebenzayo zotshintsho oluhlaza kwishishini le-polyurethane.
Phakathi kwazo, iSoleic® eyenziwe yiAlgenesis Labs itsale udumo olukhulu ngokubunjwa kwayo okusekelwe kwi-bio-based 100% kunye nokusebenza okugqwesileyo kokusingqongileyo. Njengepolyester polyol ecocekileyo kakhulu, iSoleic® ifumene ngempumelelo isatifikethi phantsi kweNkqubo yeBioPreferred® yeSebe lezoLimo lase-US (USDA)—ukwamkelwa okungqongqo okuqinisekisa ukuthobela kwayo imigangatho yamazwe ngamazwe yomxholo osekelwe kwi-bio-based, okuqinisa imeko yayo njengezinto ezivuselelekayo ngokwenene nezinobuhlobo nokusingqongileyo. Ngokungafaniyo neepolyester polyols eziqhelekileyo ezivela kwi-feedstocks ezisekelwe kwi-petroleum, uyilo oluphambili lweSoleic® lukwimithombo yayo ezinzileyo yezinto eziluhlaza: isebenzisa i-algae kunye nezityalo ezingezizo zokutya njengezinto eziphambili zemveliso. I-Algae, ubutyebi bebhayoloji obunomjikelo omfutshane kakhulu wokukhula kunye namandla okuzala aqinileyo, ayifuni nje kuphela umhlaba olimekayo (ukuphepha ukukhuphisana nemveliso yokutya) kodwa ikwafunxa inani elikhulu le-carbon dioxide ngexesha lokukhula, inegalelo ekunciphiseni ukukhutshwa kwekhabhoni. Ukufakwa kwezityalo ezingezizo zokutya ezifana ne-straw kunye ne-hemp kuphucula ngakumbi ukusebenza kakuhle kokusetyenziswa kwakhona kwezixhobo ngelixa kunciphisa ukukhutshwa kwenkunkuma yezolimo.
Okubaluleke ngakumbi, iimveliso zokugqibela ezenziwe ngeSoleic® zibonisa ukubola ngokupheleleyo. Kwiindawo zendalo (ezifana nomhlaba, amanzi olwandle, okanye iimeko zomgquba wemizi-mveliso), ezi mveliso zinokubola ngokupheleleyo ziintsholongwane zibe ngamanzi kunye ne-carbon dioxide ngaphandle kokushiya naziphi na iintsalela eziyingozi, ngokusisiseko zijongana nengxaki yongcoliseko lwe-microplastic olubangelwa ziimveliso ze-polyurethane zemveli ezilahliweyo. Okwangoku, iSoleic® isetyenziswe kakhulu kwiifoam eziguquguqukayo, ii-coating, i-adhesives, izinto zokupakisha, kunye nezinye iinkalo. Ayifezekisi nje kuphela impumelelo ekusebenzeni kokusingqongileyo kodwa ikwahlangabezana nemigangatho ephambili kushishino kwizalathisi eziphambili ezifana neempawu zoomatshini kunye nokumelana nobushushu, ifezekisa ngokwenene "ukuphumelela" phakathi kobuhlobo kokusingqongileyo kunye nokusebenza. Oku kubonelela amashishini asezantsi ngenkxaso ephambili yezinto eziluhlaza zokuphuhlisa iimveliso eziluhlaza.
Enye iteknoloji ekhethiweyo yinkqubo ye-HandiFoam® E84 enezixhobo ezimbini zokutshiza i-polyurethane foam eyasungulwa yi-ICP. Igxile kwiteknoloji yesizukulwana esilandelayo se-Hydrofluoroolefin (HFO), le mveliso igxile ekuphuculeni ukusebenza kakuhle kwamandla kunye nokwenza ngcono ukusebenza kokusingqongileyo, ifumana iSiqinisekiso seGolide se-UL GREENGUARD—ukuqatshelwa okusemthethweni kokukhutshwa kwayo okuphantsi kweVolatile Organic Compound (VOC). Esi siqinisekiso siqinisekisa ukuba i-HandiFoam® E84 ayonakalisi umgangatho womoya wangaphakathi ngexesha lokusetyenziswa, nto leyo eyenza ukuba ibe yimveliso esemgangathweni ophezulu elinganisela ukhuseleko lokusingqongileyo kunye nempilo.
Ngokuphathelele uphuhliso lwetekhnoloji, iarhente yokuvuthela ye-HFO esetyenziswa kwi-HandiFoam® E84 isebenza njengendlela enobuhlobo nokusingqongileyo kuneearhente zokuvuthela zeHydrofluorocarbon (HFC) zemveli. Xa kuthelekiswa nee-HFC, ii-HFO zine-Global Warming Potential ephantsi kakhulu (GWP), enciphisa kakhulu ukukhutshwa kwegesi ye-greenhouse kwaye inciphisa umonakalo kumaleko we-ozone. Oku kuhambelana nemigaqo-nkqubo yehlabathi yokusingqongileyo ekhuthaza iimfuno zekhabhoni ephantsi kwiifriji kunye neearhente zokuvuthela. Njengefoam ye-polyurethane yokutshiza enamacandelo amabini, i-HandiFoam® E84 ineempawu ezintle zokuthintela ubushushu kunye nokutywina, ngakumbi igqwesileyo kwicandelo lokusebenza kakuhle kwamandla esakhiwo. Xa isetyenziswa kwiindonga zangaphandle, izikhewu zomnyango/iifestile, kunye nophahla lwezakhiwo, yenza umaleko wokuvuthela oqhubekayo, oxineneyo onciphisa kakhulu ukudluliselwa kobushushu phakathi kweendawo zangaphakathi nezangaphandle, inciphisa ukusetyenziswa kwamandla kweenkqubo zomoya kunye nokufudumeza. Ngokweqikelelo, izakhiwo ezisebenzisa i-HandiFoam® E84 zinokufikelela ekunciphiseni kokusetyenziswa kwamandla ngama-20%-30%, kungekuphela nje ukonga abasebenzisi kwiindleko zamandla kodwa nokuxhasa ishishini lokwakha ekufezekiseni iinjongo zokunciphisa ukukhutshwa kwekhabhoni. Ukongeza, le mveliso inika iingenelo ezinje ngokwakhiwa okulula, ukunyangwa ngokukhawuleza, kunye nokunamathela okuqinileyo, okwenza ukuba ifaneleke kwiimeko ezahlukeneyo kuquka izakhiwo zokuhlala, izakhiwo zorhwebo, indawo yokugcina izinto ezibandayo, kunye nezixhobo zoshishino, ngaloo ndlela iqhayisa ngamathuba okusetyenziswa kwimarike ebanzi.
Isibhengezo soluhlu olufutshane lweMbasa yePolyurethane Innovation ka-2025 asiqinisekisi nje kuphela ubugcisa obutsha be-Algenesis Labs kunye ne-ICP kodwa sikwabonisa indlela yophuhliso lwehlabathi lweshishini le-polyurethane—ubuchwepheshe obusekwe kwi-bio, ukwakheka kwe-low-carbon, kunye nokusetyenziswa kwesangqa kuye kwaba ngamagama aphambili ophuhliso lwezoshishino. Phakathi koxinzelelo olukhulayo lokusingqongileyo, amashishini e-polyurethane anokufumana kuphela umda wokukhuphisana ngokugxila kwi-R&D yetekhnoloji ezinzileyo, ngelixa enegalelo kukhuseleko lwendalo lwehlabathi kunye nokufezekiswa kweenjongo zokungathathi cala kwekhabhoni. Kwixesha elizayo, ngokunciphisa okungakumbi iindleko zezinto ezikrwada ezisekwe kwi-bio kunye nokuphindaphinda okuqhubekayo kwetekhnoloji yokusingqongileyo, ishishini le-polyurethane kulindeleke ukuba lifezekise utshintsho olupheleleyo oluluhlaza, libonelela ngezisombululo zezinto ezinobuhlobo nokusingqongileyo, ezisebenzayo, nezizinzileyo kwiinkalo ezahlukeneyo zesicelo.
