1.Muuqaalka waa mid dhalaalaya oo midab leh, dusha sare ee kolloid waa mid fiican oo siman, iyo walxaha kolloid iyo mandrel ayaa si adag u xiran.Cabbirka rullaluistemadka caagga ah si adag ayaa loo xakameeyaa, cabbirkuna si weyn uma beddeli doono xaaladaha heerkulka iyo qoyaanka kala duwan.
2.Roolayaasha caagga ah ee Polyurethane waxay leeyihiin tilmaameyaal adag oo kala duwan, min HS15 ilaa HS90, kuwaas oo buuxin kara shuruudaha adkaanta ee noocyada kala duwan ee daabacadaha.
3.Kolloid-ka caagga ah ee poliurethane wuxuu leeyahay viscosity dusha sare oo ku filan si loo hubiyo in rullaluistuyada caagga ah ay leeyihiin wareejin khad wanaagsan iyo sifooyin qalin inta lagu jiro habka daabacaadda.Khadkeeda wanaagsan ayaa xaqiijin kara daabacaad tayo sare leh.
4.Polyurethane roberers-ku waxay leeyihiin sifooyin kiimiko oo wanaagsan waxayna ku habboon yihiin noocyada kala duwan ee khadadka iyo hababka daabacaadda.Waxay leedahay iska caabin gaar ah qaybaha dareeraha ee khadadka kala duwan, xalalka ilaha iyo wakiilada nadiifinta.Rollers caag Polyurethane ayaa sidoo kale ku haboon rullaluistemadka caag UV iyo rullaluistemadka caag varnished, iwm, gaar ahaan biyaha karkaraya, naaftada, shidaalka, saliidda saliidda, kerosene, toluene, khamriga iyo xal cusbo leeyihiin iska caabin ah dareere wanaagsan.Laakiin ma aha mid u adkaysata acetone, ethyl acetate iyo acids xooggan iyo alkalis.
5. Rollers caag polyurethane waxay leeyihiin sifooyin jireed oo aad u fiican.Rollers-ka caagga ah ma noqon doonaan kuwo adag oo gaboobay ka dib isticmaalka muddada dheer, waxayna leeyihiin iska caabin jeexjeex ah oo wanaagsan, adkeysi iyo caabin aad u fiican, si ay u helaan nolol dheer oo adeeg ah oo ay fududahay in la kaydiyo.Kaydinta muddada-dheer ma saamayn doonto isticmaalka.Saamaynta;awood u leh inay u adkeyso cadaadiska sare, xawaaraha sare, heerkulka sare, deegaanka wax soo saarka huurka sare.Tijaabooyinku waxay muujinayaan in xoogga jilicsanaanta iyo caabbinta caabbinta ee rollers-ka caagga ah ee poliurethane ay yihiin 3 jeer iyo 5 jeer oo ka mid ah rookaha caagga dabiiciga ah;cidhiidhiga qallafsanaanta joogtada ah iyo adkeysiga ayaa ka wanaagsan;nolosha adeegga ee rullaluistemadka caag poliurethane waa in ka badan 1 jeer in rollers caag guud.
6.Polyurethane rullaluistemadka caag ah ayaa leh hydrophilicity aad u fiican, sidaas darteed waxaa loo isticmaali karaa sida biyaha iyo aalkolada nidaamka qoyaan rullaluistemadka caag leh saamayn wanaagsan.
7.The caag poliurethane waa sahlan tahay in la nadiifiyo, fududahay in la fuliyo beddelka ee madow iyo iftiinka madow, taas oo ku habboon daabacaadda iyo midabka beddelka.
Sida soo saaraha xirfadeed ee rullaluistemadka polyurethane, Jinan Power Roller equipment Co., Ltd ma aha oo kaliya halis ah oo adag marka la eego tayada wax soo saarka, laakiin sidoo kale heer sare ah oo tignoolajiyada horumarsan.Shirkaddayadu waxay sii wadi doontaa inay soo saarto rookaha caagga ah oo tayo sare leh, waxayna ku dadaali doontaa inay noqoto soo saaraha ugu sarreeya ee rober-ka gudaha.
