1.Maonekedwe amtundu wowala, mawonekedwe a colloid ndi abwino komanso osalala, ndipo colloid colloid ndi mandrel amangiriridwa mwamphamvu.Kukula kwa mphira wodzigudubuza kumayendetsedwa mosamalitsa, ndipo kukula kwake sikungasinthe kwambiri pazikhalidwe zosiyanasiyana za kutentha ndi chinyezi.
2.Polyurethane mphira odzigudubuza ali ndi zizindikiro zambiri zowuma, kuchokera ku HS15 mpaka HS90, zomwe zingathe kukwaniritsa zofunikira za kuuma kwa mitundu yosiyanasiyana ya osindikiza.
3.The colloid for polyurethane rabara rollers ali ndi kukhuthala kokwanira pamwamba kuonetsetsa kuti odzigudubuza mphira ali ndi inki yabwino kutumiza ndi inki katundu pa ndondomeko kusindikiza.Kugwirizana kwake kwa inki kumatha kutsimikizira kusindikiza kwapamwamba.
4.Polyurethane mphira wodzigudubuza ali ndi mankhwala abwino ndipo ali oyenera mitundu yosiyanasiyana ya inki ndi njira zosindikizira.Lili ndi kukana kwapadera kwa zigawo zosungunulira mu inki zosiyanasiyana, njira zothetsera kasupe ndi zoyeretsa.Zodzigudubuza za mphira za polyurethane ndizoyeneranso zodzigudubuza za mphira za UV ndi zodzigudubuza za mphira, ndi zina zotero, makamaka madzi otentha, dizilo, petulo, mafuta odzola, palafini, toluene, mowa ndi saline solution ali ndi kukana kwabwino kwa zosungunulira.Koma sichimalimbana ndi acetone, ethyl acetate ndi asidi amphamvu ndi alkalis.
5.Polyurethane rabara odzigudubuza ali ndi makhalidwe abwino kwambiri a thupi.Odzigudubuza mphira sadzakhala ovuta komanso okalamba atagwiritsidwa ntchito kwa nthawi yaitali, ndipo ali ndi kukana kwabwino kwa misozi, kupirira komanso kukana kuvala bwino, kotero amakhala ndi moyo wautali wautumiki ndipo ndi wosavuta kusunga.Kusungirako nthawi yayitali sikungakhudze kugwiritsa ntchito.Zotsatira;amatha kupirira kuthamanga kwambiri, kuthamanga kwambiri, kutentha kwambiri, chilengedwe chopanga chinyezi.Zoyesera zikuwonetsa kuti kulimba kwamphamvu komanso kukana kwa abrasion kwa ma roller a rabara a polyurethane ndi nthawi 3 ndi nthawi 5 kuposa zodzigudubuza za rabara zachilengedwe;psinjika okhazikika mapindikidwe ndi kulimba mtima ndi bwino;moyo wautumiki wa odzigudubuza mphira wa polyurethane ndi wopitilira 1 kuposa odzigudubuza wamba.
6.Polyurethane rabara wodzigudubuza ali kwambiri hydrophilicity, kotero angagwiritsidwe ntchito ngati madzi ndi mowa dampening dongosolo labala wodzigudubuza ndi zotsatira zabwino.
7.Pulogalamu ya rabara ya polyurethane ndi yosavuta kuyeretsa, yosavuta kuchita kutembenuka kwa inki zakuda ndi zowala, zomwe zimakhala zosavuta kusindikiza ndi kusintha mtundu.
Monga katswiri wopanga zodzigudubuza mphira polyurethane, Jinan Mphamvu Wodzigudubuza zida Co., Ltd si lalikulu ndi okhwima mu mawu a khalidwe kupanga, komanso wapamwamba ndi patsogolo luso.Kampani yathu ipitiliza kupanga zodzigudubuza zapamwamba za mphira, ndikuyesetsa kukhala opanga mphira apamwamba kwambiri m'nyumba.
