I-Thiourea yinto eqakathekileko ye-sulphur enesakhiwo esifana ne-urea (ethatha indawo ye-athomu ye-oksijini nge-sulfure). Itjengisa ukuphendula kwamakhemikhali okuhlukileko, okwenza bona ibe yinto ehlukileko esetjenziswako begodu ibe yinto engezelelweko kizo zoke iimboni, zezokulima, kanye nezelabhorethri. Ngezakhiwo eziqinileko ezibonakalako nokuphendula okulawulekako, ihlangabezana namazinga wekhwalithi aqinileko wezimo ezihlukahlukeneko zokusebenzisa.
Iimpahla eziqakathekileko neenzuzo
| Ipahla | Ukucaciswa | Inzuzo eqakathekileko |
| Indawo yokuncibilika | 176 - 178°C (ibola ngaphezu kwe-180°C) | Ukuzinza kokutjhisa ngaphakathi kwamazinga womtjhiso ajayelekileko, ukubalekela ukubola ngaphambi kwesikhathi |
| Inani le-pH (1% yesixazululo samanzi) | 6.0 - 7.5 | Okungathathi ihlangothi ukuya kwe-esidi encani, okuhambisana nama-substrate amanengi ngaphandle kokubangela ukugqwala nofana ukungalingani kwe-pH |
| Ukuhlanzeka (umzuzu) | 99.0% (izinga lamabubulo); 99.5% (izinga lemithi) | Ukuhlanzeka okuphezulu kwehlisa ukusilaphazeka okungathinta ukusebenza komkhiqizo nofana kubangele ukusabela okungakalungi |
| Okuqukethwe yi-Heavy Metal (ubukhulu) | 10 ppm (Pb, Cd, Hg isibalo) | Ihlangabezana namazinga wezebhoduluko nokuphepha, ilungele ukuthintana nokudla nofana ukusetjenziswa kwemithi |
| I-Higroscopicity | Okuphasi (kudonsa umswakama omncani emazingeni womtjhiso wegumbi) | Kulula ukubulunga nokuphatha ngaphandle kokuhlangana, ukuqinisekisa ikhwalithi engaguqukiko ngokukhamba kwesikhathi |
Iinsetjenziswa ezijayelekileko
Iimpawu zamakhemikhali ezihlukileko ze-Thiourea (isib., ikghono lokwakha iinhlanganisela neensimbi, ukusebenza njenge-ejenti yokunciphisa, nokuhlanganyela ekuhlanganisweni kwe-heterocyclic) zenza bona ibe yinto eqakathekileko emabubulweni amanengi:
3.1 Izebubulo neNsimbi�
Ukucwengisiswa kwensimbi: Kusetjenziswa njenge-ejenti yokuhlanganisa igolide nesiliva (isib., ekukhipheni igolide ngaphandle kwe-cyanide) ukuncibilikisa iinsimbi eziligugu ezivela ema-ore. Isebenza njengesikhanyisi nesiqinisi ku-nickel, ikhopha, kanye ne-zinc electroplating, okwenza ngcono ukufana nokucwebezela.
Ukuvimbela ukugqwala: Kufakwa eentweni ezipholisako zebubulo, iinsombululo zokupheka, kanye namanzi wokusebenza ngensimbi ukwakha ifilimu evikelako phezu kwensimbi, ukukhandela ukugqwala nokugqwala kwe-esidi.
3.2 Ukuhlanganiswa kwamakhemikhali
Imithi namakhemikhali wezokulima: Isisetjenziswa esiphakathi esiqakathekileko ekukhiqizeni ama-sulfonamides (imithi elwa namagciwane), amahomoni we-thyroid, kanye nama-herbicides (isib., ama-herbicides asekelwe ku-thiourea wokulawula ikhula eentjalweni).
Ukukhiqizwa kwedayi nemibala: Isetjenziselwa ukwenza i-thiazole ne-imidazole, okuziingcenye eziqakathekileko zedayi ye-azo kanye nemibala ye-organic (isib., yezindwangu, amaplastiki, nama-inki).
Ibubulo lerabha: Isebenza njengesitjhugululi se-vulcanization, ikhuphula ukuthamba kwerabha, ukujamelana nokutjhisa, nokujamelana nokuguga emathayini, ama-seal, nemikhiqizo yerabha.
3.3 Ukusetjenziswa kweLabhorethri nokuKhethekileko…
Ikhemistri yokuhlaziya: Isetjenziswa njenge-reagent yokuthola nokulinganisa iinsimbi ezisindako (isib., 铋、selenium) ngokusebenzisa ukwakheka okuhlukahlukeneko.
Ukuthwebula iinthombe: Kusebenza njenge-ejenti yokulungisa nokunciphisa ekuthwebuleni iinthombe ezimnyama nezimhlophe, isiza ukuqinisa iinthombe nokususa ama-halide wesiliva angabonakaliko.
Ukuphepha nokuthobela
4.1 Imihlahlandlela yokuPhepha
Ukuphatha: Balekela ukuhogela ithuli nofana ukuthintana nesikhumba/amehlo ngqo. Yembatha amagilasi angangenwa lithuli, amagilavu we-nitrile, kanye nemaski yokuphefumula (i-N95 nofana ngaphezulu) eendaweni ezingangeni umoya omuhle. Hlamba izandla kuhle ngesibha namanzi ngemva kokuthintana.
Ukubulunga: Beka endaweni epholileko, eyomileko, enomoya omuhle kude nama-asidi aqinileko (isib., i-hydrochloric acid), izinto ezikhiqiza i-oksijini (isib., i-hydrogen peroxide), namalangabi avulekileko. Sebenzisa i-HDPE evaliweko nofana amadrum wefayibha ukukhandela ukumunywa komswakama nokusilaphazeka.
Ukulahla: Lahla iimfesi nofana i-thiourea engasetjenziswa ngokuya kwemithetho yezebhoduluko yendawo (isib., njengemfesi engasiyingozi yezebubulo; balekela ukuyikhupha ehlabathini nofana emanzini).
4.2 Ukuthobela imithetho
Ikhambisana nomThetho we-REACH (EU) (itloliswe ngaphasi kwerhelo le-REACH SVHC, akukho mikhawulo yokusetjenziswa emabubulweni).
Ihlangabezana namazinga we-FDA (ukusetjenziswa kokuthintana nokudla, isib., njengesivimbeli sokugqwala emitjhini yokusebenza ukudla).
Ikhambisana namazinga we-USP/NF (izinga lemithi) ukusetjenziswa ekuhlanganisweni kwemithi.
Iqinisekiswe yi-ISO 9001 (ukuphathwa kwekhwalithi) kanye ne-ISO 14001 (ukuphathwa kwebhoduluko) ngeenkambo zokukhiqiza.
Iphepha ledatha yezobuchwepheshe (TDS) amaphuzu aqakathekileko

Kubayini Sikhetha I-Thiourea Yethu?
Amagreyidi enziwe ngokwezifiso: Sinikela ngamagreyidi wezebubulo, wezokwelapha, newelabhorethri ukuhlangabezana neendingo ezithileko zamakhasimende (isib., okuqukethwe okuphasi kwensimbi ebudisi yokusetjenziswa kwemithi).
Ukuphakelwa okuzinzileko: Iindawo zethu zokukhiqiza (ezinamandla wamathani ayi-5,000 ngonyaka) ziqinisekisa ukulethwa ngesikhathi, ngitjho nakuma-oda amanengi (amadram ama-20-500 kg).
Isekelo lobuthekhnikhi: Isiqhema sethu samakhemikhali sinikela ngokubonisana kwangaphambi kokuthengisa (isib., ukumadanisa isicelo) kanye nokusekela ngemva kokuthengisa (isib., ukurarulula imiraro yokucubungula).
Ukukhiqiza Okungalimazi Ibhoduluko: Ikambiso yethu yokukhiqiza yehlisa amanzi angcolileko nokukhutjhwa, ngokukhambisana nemigomo yokusimama yephasi loke.
