Chabwino n'chiti, mphira yekha kapena PU yekha?

Ndi kusintha kwa moyo wa aliyense, aliyense wayamba kukhala ndi moyo wapamwamba m'mbali zonse.Zilinso mu kusankha nsapato.Zomwe zimabweretsedwa ndi nsapato zosiyana zimakhalanso zosiyana.Zomwe zimafala kwambiri ndi nsapato za mphira ndi nsapato za polyurethane.

Kusiyana:

Zopangira mphira zimakhala ndi ubwino wokhala ofewa komanso zotanuka, koma sizimamva kuvala.Miyendo ya mphira imapangidwa ndi zinthu za polima monga zopangira;pamene azitsulo za polyurethanendi zopepuka kwambiri, zokhala ndi chiŵerengero chapamwamba chomatira komanso chitonthozo, komanso zomangira zake zimakhalanso zosamva kuvala.

Zomwe zili bwino, mphira yekha kapenapolyurethane yekha?

Zilibe kanthu kuti nsapato ziwirizi ndi ziti zomwe zili bwino, ndiye kuti ndi sole iti yomwe ili yoyenera pamwambo uti.Rubber sole ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri pa nsapato zotetezera.Ili ndi mphamvu zotsutsana ndi dzimbiri komanso kukana kuvala.Ndi ma polima opangidwa ndi ma polima omwe samangokhalira kusungunuka kwambiri, komanso amakhala ndi kukana kwa mavalidwe apamwamba ndi kusinthasintha, ndipo amatha kupirira Kupindika, kutambasula, ndi kuponderezana popanda kuwonongeka;

Chovala cha polyurethane ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri pa nsapato wamba, zopepuka komanso zomasuka kuvala.Nthawi zambiri amapanga thovu zosiyanasiyana popanga, ndipo amakhala ndi mawonekedwe a elasticity, kulemera kopepuka, kukana mafuta, ndi zina zambiri, ndipo amakhala omasuka komanso zotanuka kuvala.Miyendo ya polyurethane ndiyosavuta kupanga ndi kupanga.Iwo amapangidwa ndi sitepe imodzi akamaumba ndondomeko popanda kugwirizana, amene amapulumutsa ntchito ndi nthawi.Sizopindulitsa kokha ku thanzi la opanga, komanso sichiipitsa chilengedwe, chomwe chimathandiza kwambiri kupanga bwino.
