Mashoko Akakosha Echinyorwa: Thiourea, Zvishandiso zveThiourea, Vagadziri veThiourea
Thiourea inoshandiswa munzvimbo dzakasiyana-siyana, kushandiswa kwayo kwakasiyana-siyana kunokonzerwa nehunyanzvi hwayo hwemakemikari akasiyana uye mabasa ayo akasiyana-siyana.
Chekutanga uye chinonyanya kukosha, thiourea ine basa guru mukugadzirwa kwezvinhu zvakasikwa.
Inoshanda sechinhu chakakosha, chinoshandiswa mukugadzirwa kwemakemikari akasiyana-siyana eorganic - kusanganisira mishonga, madhayi, nemishonga yezvipembenene.
Thioureaine basa guru muindasitiri yerabha. Inoshanda senzira yekukurumidzisa rabha, ichivandudza mwero uye huwandu hwemaitiro ekurumidzisa rabha, nokudaro ichivandudza hunhu hwechinhu chacho uye hwekugadzirisa. Kubatanidzwa kwethiourea kunoita kuti zvigadzirwa zverabha zvigare kwenguva refu uye zvinake, zvichizadzisa zvinodiwa nemaindasitiri akasiyana-siyana.
Uyezve, thiourea chinhu chakakosha mukuputira goridhe. Muindasitiri yekuputira goridhe, inoshanda sechinhu chinowedzera kumabhati ekuputira goridhe, ichivandudza kufanana uye kupenya kwejira rakaputirwa uye zvichikonzera zvigadzirwa zvakaputirwa goridhe zvinofadza runako uye zvinogara kwenguva refu. Panguva imwe chete, thiourea inogona kushandiswa mumabasa ekugadzira simbi dzesimbi—dzakadai sesirivha nemhangura—ichipa rutsigiro rwakakosha rwezvinhu zvakachekwa kuchikamu chekuputira goridhe. Kunze kwekushandiswa kwataurwa pamusoro apa, thiourea inoshandiswawo mukuongorora kemikari, uko inoshanda se reagent kana chiratidzo mune mamwe maitiro emakemikari.
Hunhu hwayo hwemakemikari hwakasiyana hunopa thiourea mukana wekushandiswa mumunda wekuongorora makemikari. Zvisinei, matanho ekudzivirira anofanirwa kuteverwa pakubata thiourea.
Semuenzaniso, thiourea inofanira kuchengetwa munzvimbo inotonhorera, yakaoma uye kuchengetedzwa kure nezvinhu zvakaita se oxidizing agents uye acids kudzivirira makemikari anogona kukonzera kuora kana mamiriro ezvinhu ane njodzi.
Pamusoro pezvo, pakushandisa thiourea mukuita kwemakemikari, kudzora zvakanyanya maparamita ekuita—akadai setembiricha uye pH—kwakakosha kuti kuve nechokwadi chekuti kuita kwekuita kwakanaka uye kuchena kwechigadzirwa chinobuda.
Semutengesi wethiourea, Aojin Chemical inopathioureayemhando yepamusoro uye ine mhando dzakasiyana dzezvishandiso zvekushandisa se vulcanization accelerator. Yakaiswa mumabhegi e25kg, chigadzirwa chedu chakagadzirirwa kusangana nezvinodiwa zvakasiyana-siyana zvemashandisirwo akasiyana-siyana. Tinokukoka kuti utibate kuti uwane rumwe ruzivo.
