Polyirethane ndi amodzi mwazinthu zodziwika bwino padziko lonse lapansi, koma nthawi zambiri zimawanyalanyaza m'miyoyo yathu ya tsiku ndi tsiku. Komabe kaya muli kunyumba, kuntchito kapena m'galimoto yanu, nthawi zambiri kumakhala kutali, ndikugwiritsa ntchito njira zofananira kuchokera kuma matiresi ndi mipando yotupa kuti ipangitse kutchinjiriza, magalimoto ngakhale mafashoni a nsapato.

Koma monga ma pulasitiki ena omwe amasautsa kwambiri, kugwiritsa ntchito kofala kwaPolyirethanezimakhudza zovuta za chilengedwe chake. Kuti mumvetsetse mwayi wobwezeretsa polyirethacting ndikusintha mankhwala omwe amagwiritsidwa ntchito popanga labotale ya ku US. Phunziroli lidasindikizidwa posachedwa munkhaniyiChilengedwe Chachilengedwe & Technology.

"Cholinga chake chinali kumvetsetsa momwe ma pointrathanes amagwirira ntchito ku United States," anafotokozera mlembi Dunn, yemwe ndi wotsogolera ndi chilengedwe ndi mphamvu yakumpoto chakumadzulo kwa Northweustern (Isn). "Tinkafunanso kuwona ngati pali mwayi wozungulira kuzungulira ndikuwonjezera zomwe zidachokera ku polyuretharethanes."

Chuma cha mzere ndi chimodzi chomwe chimagwiritsidwa ntchito kupanga zinthu kenako chimatayidwa kumapeto kwa moyo wawo. Pachuma chozungulira, zinthu zomwezi zimawonekeranso ndikugwiriridwa. Izi zimachepetsa kufunika kochotsa zinthu zachilengedwe zowonjezera, monga mafuta osungiramo zinthu zakale, ngakhale kuchepetsa kuchuluka kwa zinyalala zomwe zimatumizidwa kumoto.

Dunn, yemwenso ndi purotesa wochezera wa mankhwala a McCorming ku Northerter a Northerter a Northerter a Northerter a Northerter a Northerter

Malinga ndi wolemba Troy Hawkins, omwe amachititsa kuti magetsi ndi gulu lazinthu zoyeserera ku Argonne
