Zinthu zapadziko lapansi ndizochepa ndipo ndikofunikira kuti tingotenga zomwe tikufuna ndikuchita gawo lathu kuti titeteze zomwe zatsala ku mibadwo yamtsogolo.Ma polyurethanes amagwira ntchito yofunika kwambiri poteteza zachilengedwe za dziko lathu lapansi.Zovala zolimba za polyurethane zimatsimikizira kuti moyo wazinthu zambiri umachulukira kuposa zomwe zikanatheka popanda zokutira.Ma polyurethanes amathandizira kusunga mphamvu moyenera.Amathandizira omanga nyumba kuti azitsekera bwino nyumba zomwe zimachepetsa kugwiritsa ntchito gasi, mafuta ndi magetsi, zomwe zikadafunika kuzitenthetsa ndi kuziziziritsa.Chifukwa cha opanga magalimoto a polyurethanes amatha kupanga magalimoto awo mowoneka bwino ndikupanga mafelemu opepuka omwe amasunga mafuta ndi mpweya.Kuphatikiza apo, thovu la polyurethane lomwe limatsekera mufiriji kumatanthauza kuti chakudya chimasungidwa nthawi yayitali ndikuchiteteza kuti chisawonongeke.

Komanso kupulumutsa mphamvu ndi kuteteza chuma chamtengo wapatali, palinso chidwi chowonjezereka pakuwonetsetsa kuti zinthu za polyurethane sizingotayidwa kapena kutayidwa zikafika kumapeto kwa moyo wawo wachilengedwe.

Chifukwa ndi polyurethanesma polima opangidwa ndi petrochemical, m’pofunika kuti tiziwagwiritsanso ntchito ngati n’kotheka, kuti zinthu zamtengo wapatali zisawonongeke.Pali njira zingapo zobwezeretsanso, kuphatikiza makina ndi mankhwala obwezeretsanso.

Kutengera mtundu wa polyurethane, njira zosiyanasiyana zobwezeretsanso zitha kugwiritsidwa ntchito, monga kugaya ndikugwiritsanso ntchito kapena kulumikiza tinthu.Mwachitsanzo, thovu la polyurethane, nthawi zonse limasandulika kukhala pansi pa kapeti.

Ngati sichikubwezeretsedwanso, njira yabwino ndikubwezeretsa mphamvu.Tonne ya tonne, polyurethane ili ndi mphamvu yofanana ndi malasha, zomwe zimapangitsa kuti ikhale chakudya chokwanira kwambiri chamagetsi opangira magetsi omwe amagwiritsa ntchito mphamvu zopangira kutentha nyumba za anthu.

Njira yosafunikira kwambiri ndiyo kutayira, yomwe iyenera kupewedwa ngati kuli kotheka.Mwamwayi, chisankhochi chikuchepa kwambiri pamene maboma padziko lonse lapansi akudziwa bwino za kufunika kwa zinyalala pokonzanso ndi kubwezeretsa mphamvu, komanso pamene mayiko akutha mphamvu zawo zotayira.

Makampani a polyurethane akupanganso zatsopano kuti apange zinthu zokhazikika.
