Anthu omwe ali m'makampani amadziwa kuti pali njira zingapo zodulira ngodya zakunja, mwina kugwiritsa ntchito matope a polymer kuti atulutse bolodi, kapena malo osungirako osungirako sakwaniritsa matope a polymer. Koma ngati ndikuthamanga nthawi yomanga, anthu ambiri amachepetsa njira zomangamanga.
Koma zomwe ndikufuna kugawana nanu lero si ngodya zakunja, koma njira ina yakunja yothetseratu. Ndikudabwa ngati mwaziwona? Pofuna kufutula patsogolo pa zomangamanga, zinthu zomwe zikufanana ndi thonje la polyurethane zimagwiritsidwa ntchito poika makulidwe akunja? Ndiye kodi zotsatira zake ndi ziti?
Uku ndi chithovu cha polyurethane chomatira, zomata za polyurethane zomata zamphamvu kwambiri. Koma chonde dziwani kuti uyu si wololeza pouningtane yemwe timakonda kugwiritsa ntchito.
Njira yotsatsira ndiyofanana ndi njira ya matope. Choyamba, utsi wa mankhwala a polyurethane pamtunda wa bolodi yotchinga. Kenako konzani ndikudikirira kuti guluu lizikhazikike.
Zotsatira zake ndi mgwirizano wabwino komanso wamphamvu. Mutha kulingalira za zomata za chithovu chopangidwa ndi Junbond.
