eThiourea
Intshayelelo yemveliso
I-Thiourea yi-organic sulfur compound, i-chemical formula CH4N2S, i-crystal emhlophe kunye ne-glossy crystal, incasa ekrakra, ubuninzi be-1.41g / cm³, i-melting point 176 ~ 178℃. Isetyenziselwa ukwenza iziyobisi, iidayi, iirasi, umgubo wokubumba kunye nezinye izinto eziluhlaza, ezikwasetyenziswa njenge-rubber vulcanization accelerator, i-agent ye-metal mineral flotation njalo njalo. Yenziwa ngesenzo sehydrogen sulfide kunye nekalika eludaka ukwenza icalcium hydrosulfide kunye necalcium cyanamide. Isenokulungiswa ngokunyibilikisa i-ammonium thiocyanide, okanye ngokwenza i-cyanamide ngehydrogen sulfide.
Isalathiso soBugcisa
Ukusetyenziswa
I-Thiourea isetyenziswa kakhulu njengezinto eziluhlaza zokwenziwa kwe-sulfathiazole, i-methionine kunye nezinye iziyobisi, kwaye inokusetyenziswa njengesixhobo ekrwada kwidayi kunye nezinto ezincedisayo zokudaya, iintlaka kunye nomgubo wokubumba, kwaye ingasetyenziswa njenge-vulcanization accelerator yerabha. , i-agent ye-flotation ye-metal minerals, i-catalyst yokuveliswa kwe-phthalic anhydride kunye i-fumaric acid, kunye ne-metal rust inhibitor. Ngokubhekiselele kwizinto eziphathekayo zefoto, inokusetyenziswa njengomphuhlisi kunye ne-toner, kwaye ingasetyenziselwa kwishishini le-electroplating. I-Thiourea ikwasetyenziswa kwiphepha le-diazo photosensitive, i-synthetic resin coatings, i-anion exchange resins, abagqugquzeli bokuhluma, imichiza yokungunda kunye neminye imiba emininzi. I-Thiourea ikwasetyenziswa njengesichumisi. Isetyenziselwa ukwenza iziyobisi, iidayi, iirasi, umgubo wokubumba, irabha vulcanization accelerator, i-metal mineral flotation agents kunye nezinye izinto ezikrwada.
