1. Muuqaalku waa mid dhalaalaya, dusha sare ee kolloidku waa mid fiican oo siman, walxaha kolloidku iyo mandrelkuna si adag ayay isugu xiran yihiin. Cabbirka roller-ka caagga ah si adag ayaa loo xakameeyaa, cabbirkuna si weyn uma beddeli doono xaaladaha heerkulka iyo qoyaanka kala duwan.
2. Rullaluisteyaasha caagga ah ee Polyurethane waxay leeyihiin tiro badan oo tilmaameyaal adag ah, laga bilaabo HS15 ilaa HS90, kuwaas oo dabooli kara shuruudaha adag ee noocyada kala duwan ee daabacayaasha.
3. Colloid-ka loogu talagalay duubayaasha caagga ah ee polyurethane wuxuu leeyahay daxal ku filan oo dusha sare ah si loo hubiyo in duubayaasha caaggu ay leeyihiin sifooyin wareejin khad oo wanaagsan iyo astaamo khad ah inta lagu jiro habka daabacaadda. Xidhiidhkiisa khad ee wanaagsan wuxuu hubin karaa daabacaad tayo sare leh.
4. Rulabyada caagga ah ee Polyurethane waxay leeyihiin sifooyin kiimiko oo wanaagsan waxayna ku habboon yihiin noocyada kala duwan ee khadyada iyo hababka daabacaadda. Waxay leedahay iska caabin gaar ah oo ku wajahan qaybaha dareeraha ah ee khadyo kala duwan, xalalka isha iyo walxaha nadiifinta. Rulabyada caagga ah ee Polyurethane waxay sidoo kale ku habboon yihiin rulabyada caagga ah ee UV iyo rulabyada caagga ah ee la dahaadhay, iwm., gaar ahaan biyaha karkaraya, naaftada, shidaalka, saliidda saliidda, gaaska, toluene, khamriga iyo xalka milixda leh waxay leeyihiin iska caabin wanaagsan oo dareere ah. Laakiin uma adkaysato acetone, ethyl acetate iyo asiidhyada xooggan iyo alkalis.
5. Rulabyada caagga ah ee Polyurethane waxay leeyihiin sifooyin jireed oo aad u fiican. Rulabyada caagga ah ma adkaan doonaan oo gaboobayaan ka dib isticmaalka muddada dheer, waxayna leeyihiin iska caabin wanaagsan oo jeexjeex ah, adkeysi iyo iska caabin heer sare ah oo xirashada, sidaa darteed waxay leeyihiin cimri adeeg dheer waana ay fududahay in la kaydiyo. Kaydinta muddada dheer saameyn kuma yeelan doonto isticmaalka. Saameyn; awood u leh inay u adkeysato cadaadis sare, xawaare sare, heerkul sare, jawi wax soo saar qoyaan sare leh. Tijaabooyinku waxay muujinayaan in xoogga jiidista iyo iska caabinta xoqidda ee rulabyada caagga ah ee polyurethane ay yihiin 3 jeer iyo 5 jeer ka badan rulabyada caagga ah ee dabiiciga ah; isbeddelka joogtada ah ee cadaadiska iyo adkeysiga ayaa ka wanaagsan; cimriga adeegga ee rulabyada caagga ah ee polyurethane waxay ka badan tahay 1 jeer rulabyada caagga ah ee guud.
6. Roogga caagga ah ee Polyurethane wuxuu leeyahay hydrophilicity aad u fiican, sidaa darteed waxaa loo isticmaali karaa sida roog caag ah oo biyaha iyo khamriga ah oo leh saameyn wanaagsan.
7. Roogga caagga ah ee polyurethane waa mid si fudud loo nadiifin karo, si fududna loo fulin karo beddelka khad madow iyo mid fudud, kaas oo ku habboon daabacaadda iyo beddelka midabka.
Maadaama ay tahay soo saare xirfadle ah oo sameeya duubista caagga polyurethane, qalabka Jinan Power Roller Co., Ltd ma aha oo kaliya mid halis ah oo adag marka la eego tayada wax soo saarka, laakiin sidoo kale waa mid heer sare ah oo horumarsan oo ku saabsan tiknoolajiyada. Shirkaddayadu waxay sii wadi doontaa inay soo saarto duubista caagga tayo sare leh, waxayna ku dadaali doontaa inay noqoto soo saaraha duubista caagga ee ugu sarreeya gudaha.
