Thiourea
Isingeniso somkhiqizo
I-Thiourea iyinhlanganisela yesulphur ephilayo, ifomula yamakhemikhali engu-CH4N2S, ikristalu emhlophe necwebezelayo, ukunambitheka okubabayo, ukuminyana okungu-1.41g/cm³, indawo encibilikayo 176 ~ 178℃. Isetshenziswa ekwakhiweni kwezidakamizwa, odayi, ama-resin, impushana yokubumba nezinye izinto ezingavuthiwe, ezibuye zisetshenziswe njenge-accelerator ye-rubber vulcanization, i-ejenti yensimbi ye-flotation yensimbi nokunye. Yakhiwa isenzo se-hydrogen sulfide ne-lime slurry ukuze yakhe i-calcium hydrosulfide bese kuba i-calcium cyanamide. Ingabuye ilungiswe ngokuncibilikisa i-ammonium thiocyanide, noma ngokwenza i-cyanamide nge-hydrogen sulfide.
Inkomba Yezobuchwepheshe
Ukusetshenziswa
I-Thiourea isetshenziswa kakhulu njengezinto ezingavuthiwe zokwenziwa kwe-sulfathiazole, i-methionine nezinye izidakamizwa, futhi ingasetshenziswa njengempahla eluhlaza yodayi nezinsizi zokudaya, ama-resin kanye nezimpushana zokubumba, futhi ingasetshenziswa njengesisheshisi se-vulcanization senjoloba. , i-ejenti yokuntanta yamaminerali ensimbi, i-catalyst yokukhiqizwa kwe-phthalic anhydride kanye i-fumaric acid, futhi njenge-metal rust inhibitor. Ngokuphathelene nezinto zezithombe, ingasetshenziswa njengomthuthukisi kanye ne-toner, futhi ingasetshenziswa embonini ye-electroplating. I-Thiourea iphinde isetshenziswe ephepheni le-diazo photosensitive, i-synthetic resin coatings, ama-anion exchange resins, abagqugquzeli bokuhluma, ama-fungicides nezinye izici eziningi. I-Thiourea nayo isetshenziswa njengomanyolo. Isetshenziswa ekwenzeni izidakamizwa, odayi, izinhlaka, powder ukubumba, iraba vulcanization accelerator, metal amaminerali flotation agents kanye nezinye izinto zokusetshenziswa.
