Thiourea
Chiyambi cha malonda
Thiourea ndi organic sulfure pawiri, mankhwala chilinganizo CH4N2S, woyera ndi glossy kristalo, kukoma kowawa, kachulukidwe 1.41g/cm³, kusungunuka mfundo 176 ~ 178 ℃. Ntchito kupanga mankhwala, utoto, utomoni, akamaumba ufa ndi zipangizo zina, komanso ntchito ngati mphira vulcanization accelerator, zitsulo mchere flotation wothandizira ndi zina zotero. Amapangidwa ndi zochita za hydrogen sulfide ndi laimu slurry kupanga calcium hydrosulfide kenako calcium cyanamide. Itha kukonzedwanso posungunula ammonium thiocyanide, kapena pochita cyanamide ndi hydrogen sulfide.

Kugwiritsa ntchito
Thiourea amagwiritsidwa ntchito makamaka ngati zopangira popanga sulfathiazole, methionine ndi mankhwala ena, ndipo angagwiritsidwenso ntchito ngati zopangira utoto ndi utoto wothandiza, utomoni ndi akamaumba ufa, komanso angagwiritsidwe ntchito ngati vulcanization accelerator kwa labala. , chinthu choyandama cha mchere wachitsulo, chothandizira kupanga phthalic anhydride ndi fumaric acid, komanso ngati choletsa dzimbiri lachitsulo. Pankhani ya zida zojambulira, zitha kugwiritsidwa ntchito ngati wopanga ndi tona, komanso zitha kugwiritsidwa ntchito pamakampani opanga ma electroplating. Thiourea imagwiritsidwanso ntchito mu pepala la diazo photosensitive, zokutira zopangira utomoni, utomoni wosinthira wa anion, olimbikitsa kumera, mankhwala opha fungicides ndi zina zambiri. Thiourea imagwiritsidwanso ntchito ngati feteleza. Ntchito kupanga mankhwala, utoto, utomoni, akamaumba ufa, mphira vulcanization accelerator, zitsulo mchere flotation wothandizira ndi zipangizo zina.
