Diphenylcarbamide CAS:102-07-8

Motswakong wa tlhaho, diphenylcarbamide e sebediswa e le mokedi wa bohlokwa bakeng sa ho lokisa metswako e fapaneng ya tlhaho, ho kenyeletswa meriana le dikhemikhale tsa temo. E sebetsa e le motheo wa kaho o nang le mesebetsi e mengata, e dumellang ho kenngwa ha tshebetso e tswang ho urea ka hara dimolekhule tse rerilweng. Sena se nolofalletsa ho thehwa ha dihlahiswa tse fapaneng tse nang le mesebetsi e ikgethang ya baeloji kapa ditshebediso tsa temo, e leng se thusang ntshetsopeleng ya di-agent tse ntjha tsa kalafo le ditharollo tsa tshireletso ya dijalo. Ho feta moo, diphenylcarbamide e sebediswa e le moemedi wa ho hokahanya k'hemistri ya polymer, moo e sebetsang e le moemedi wa ho phekola ho hokahanya diketane tsa polymer mmoho. Tshebetso ena, e tsejwang e le urethane crosslinking, e ntlafatsa matla a mechini, ho tshwarella le botsitso ba mocheso ba thepa ya polymer. Ka lebaka leo, diphenylcarbamide e thusa tlhahisong ya di-polymer tse sebetsang hantle tse sebediswang ditshebedisong tse fapaneng tsa indasteri, tse kang dikhomaretsi, dikobo le thepa e kopaneng, e tshehetsang kgatelopele saenseng ya thepa le boenjiniere. Ho feta moo, diphenylcarbamide e ka sebediswa indastering ya dae bakeng sa ho kopanya didae tse thehilweng ho urea. Bokgoni ba yona ba ho etsa dikarabelo tsa ho kenya dihlopha tse itseng tse sebetsang ka hara dimolekhule tsa dae bo dumella tlhahiso ya didae tse phelang le tse sa fetoheng tse loketseng masela, kgatiso le ditshebediso tse ding. Karolo ea motsoako ona tlhahisong ea dae e tšehetsa ho thehoa ha mebala le meriti e mengata e hlokahalang indastering ea masela le feshene, e tlatsetsang nts'etsopele ea thepa e ncha le e khahlang ka botle. Ka bokhutšoanyane, diphenylcarbamide ke motsoako o feto-fetohang o nang le lits'ebetso tse kholo tsa indasteri. Karolo ea oona e le reactant tlhahisong ea lintho tse phelang le e le moemeli oa ho hokahanya lik'hemistri tsa polymer e totobatsa bohlokoa ba oona ho tšehetseng tsoelo-pele lipatlisisong tsa meriana, saense ea thepa, le tlhahiso ea lik'hemik'hale tse ikhethang. Thepa e ikhethang ea motsoako ona le ts'ebeliso e fapaneng e totobatsa bohlokoa ba oona e le thepa ea bohlokoa masimong a k'hemistri ea lintho tse phelang, saense ea polymer le tlhahiso ea dae.
