Igitigiri ca CAS: 62-56-6
Igishushanyo c'amamolekule: CH4N2S
Uburemere bw'ibinyabuzima: 76,12 g/mol
Uko igaragara: Ifu y’ikibiriti yera canke prills; nta mpumuro canke ifise akamoto gatoyi kameze nk’aka amoniya
Ugusenyuka: Gusenyuka cane mu mazi (137 g/L ku 20°C), gusenyuka muri éthanol, gusenyuka gatoyi muri ether na acetone
Thiourea ni ikirungo gihambaye c’ibinyabuzima gifise imiterere imeze nk’iya urea (gisubirira atome y’umwuka w’ikibiriti n’ikibiriti). Igaragaza ubushobozi budasanzwe bwo gukorana n’imiti, bikaba biyigira igikoresho gikoreshwa mu buryo bwinshi be n’ivyo kwongerako mu bikorwa vy’inganda, uburimyi n’ivy’ama laboratwari. Kubera ko ifise imiterere y’umubiri idahinduka be n’ubushobozi bwo gusubiramwo, irahuye n’ingingo mfatirwako zikomeye z’uburyo bwo gukoresha ibintu bitandukanye.
Ibintu nyamukuru n'ivyiza
| Umutungo | Ibisobanuro | Inyungu nyamukuru |
| Ikibanza co gushongera | 176 - 178°C (ibora hejuru ya 180°C) | Ugushikama kw'ubushuhe mu bushuhe busanzwe bwo gutunganya, kwirinda kubora vuba |
| Agaciro ka pH (1% y'amazi) | 6,0 - 7,5 | Itagira aho igarukira canke igira aside nkeyi, ihuye n’ibintu vyinshi bitagira aho bigarukira ataco bitera gusenyuka canke ukudahukana kwa pH |
| Ubusuku (min) | 99,0% (urugero rw’inganda); 99.5% (ikigero c'imiti) | Ubusuku bwinshi buragabanya ubuhumane bushobora gutuma igicuruzwa gikora neza canke kigatuma habaho ingaruka mbi |
| Ibirimwo ivyuma biremerera (max) | 10 ppm (Pb, Cd, Hg vyose hamwe) | Ihuye n'ingingo mfatirwako z'ibidukikije n'umutekano, zibereye gukoreshwa mu gukorana n'ibifungurwa canke imiti |
| Ubushobozi bwo gufata amazi | Hasi (inywa ubukonje bukeyi mu bushuhe bwo mu cumba) | Biroroshe kubika no gukoresha ata gufatanya, kumenya neza uburyo buhoraho uko igihe kigenda kirarenga |
Ibikorwa bisanzwe
Ivyo thiourea ifise (nk’akarorero, ubushobozi bwo gukora ibintu bikomeye n’ivyuma, gukora nk’ikintu kigabanya, no kugira uruhara mu gukora ibintu bitandukanye) bituma iba ikintu gihambaye cane mu bikorwa vyinshi:
3.1 Inganda n'ubucuzi bw'ivyuma
Metal Refining & Plating: Ikoreshwa nk’ikintu gikomeye mu gukura inzahabu n’ifeza (nk’akarorero, mu gukura inzahabu idafise cyanide) kugira ngo ivyuma vy’agaciro bive mu mabuye y’agaciro. Ikora nk’ikintu gica ibibatsi kandi kigatuma ibintu biguma bimeze neza mu gutera ivyuma vy’umuringa, umuringa n’ivyuma vy’umuringa, kigatuma ivyuma bimera neza kandi bikaba bimeze neza.
Ivyo Gukingira Ivyuma: Bishirwa mu bikoresho bikonjesha mu nganda, mu bikoresho vyo gutera ivyatsi be no mu bikoresho vyo gukora ivyuma kugira ngo bibe nk’igipande co gukingira ivyuma, bikaba bikingira umugese n’ugusenyuka kw’aside.
3.2 Ihuriro ry'imiti
Imiti n’Imiti y’uburimyi: Igikoresho nyamukuru co guhingura sulfonamides (imiti irwanya imigera), amahormone y’umubiri, n’imiti yica ivyatsi bibi (nk’akarorero, imiti yica ivyatsi bibi ishingiye kuri thiourea yo gukingira ivyatsi bibi mu bihingwa).
Irangi n’Irangi: Bikoreshwa mu gukora ibintu biva kuri thiazole na imidazole, ari vyo bihimba bihambaye cane vy’irangi rya azo n’irangi ry’ibinyabuzima (nk’akarorero, ku mpuzu, amapulasitike, n’amarangi).
Inganda y’Imipira: Ikora nk’ikintu gituma imipira yihuta kandi igahindurwa, igatuma imipira igira ubushobozi bwo gukomera, igashobora guhangana n’ubushuhe, kandi igashobora guhangana n’ugukura mu mapine, mu bipfukisho, no mu bikoresho vy’imipira.
3.3 Laboratwari n'Ikoreshwa ry'Ibintu Bidasanzwe
Ivy’Isesengura: Bikoreshwa nk’igikoresho co kumenya no gupima ivyuma biremerera (nk’akarorero, 铋、selenium) biciye mu guhingura ibintu bikomeye.
Amafoto: Akora nk’ikintu gikomeza n’ikigabanya mu mafoto y’umwirabura n’umweru, agafasha gutuma amashusho aguma ahagaze neza no gukuraho amahalide y’ifeza atagaragara.
Umutekano n'Ukugendera
4.1 Amabwirizwa yerekeye umutekano
Uko wovyifatamwo: Irinde guhema inkungugu canke gukorana n’urukoba/amaso. Ambara amataratara adashobora guterwa n’inkungugu, amaganzu y’amazi, n’igipfukisho co guhema (N95 canke kirenze) ahantu hatagira umwuka mwiza. Woze neza ibiganza n’amazi n’isabune umaze gukorana navyo.
Ububiko: Bibike mu bubiko bukonje, bwumye, bufise umwuka mwiza, kure y’aside zikomeye (nk’akarorero, aside y’amazi), ibintu bitera umwuka (nk’akarorero, peroxyde d’hydrogène), n’imbeya zifunguye. Koresha ingoma za HDPE canke z’insinga zipfutse kugira ngo ntizinywe n’ubukonje kandi ntizihumanye.
Guta: Guta imyanda canke thiourea idakoreshwa hakurikijwe amategeko agenga ibidukikije yo mu karere (nk’akarorero, nk’imyanda y’inganda idatera akaga; wirinde kuyirekura mw’ivu canke mu mazi).
4.2 Kwubahiriza amategeko
Ihuye n’Itegeko rya REACH (EU) (ryandikishijwe munsi ya list ya REACH SVHC, nta n’umwe abujijwe gukoresha mu nganda).
Ihuye n’ingingo ngenderwako za FDA (ku bikorwa bikorana n’ibifungurwa, nk’akarorero, nk’ikintu kizibira uburozi mu bikoresho vyo gutunganya ibifungurwa).
Ihuye n’ingingo ngenderwako za USP/NF (urugero rw’imiti) zo gukoreshwa mu guhingura imiti.
Ivyemejwe na ISO 9001 (uburongozi bw’uburyo) na ISO 14001 (uburongozi bw’ibidukikije) ku bijanye n’imigenderanire y’uguhingura.
Urupapuro rw'amakuru y'ubuhinga (TDS) Ibintu bihambaye
| Imirongo | Igitigiri c'inganda | Igitigiri c'imiti | Uburyo bwo kugerageza |
| Ubusuku | ≥99.0% | ≥99.5% | Ivyuma vy'amazi bikora neza cane (HPLC) |
| Ibirimwo ubukonje | ≤0.5% | ≤0.3% | Ugupima kwa Karl Fischer |
| Ivu ry'ibirimwo | ≤0.1% | ≤0.05% | Isesengura ry'uburemere bw'isi |
| Icuma (Fe) | ≤5 ppm | ≤2 ppm | Igishushanyo c'umuco w'atome (AAS) |
| Ibintu bidashobora gusenyuka mu mazi | ≤0.01% | ≤0,005% | Kuyungurura no kwumisha |
Ni kuki duhitamwo Thiourea yacu?
Ivyiyumviro vy’abantu: Turatanga ivyigwa vy’inganda, ivy’imiti, n’ivy’ama laboratwari kugira ngo dushobore gushitsa ivyo abakiriya bakeneye (nk’akarorero, ivyuma biremerera bike bikoreshwa mu vy’imiti).
Ivyo dutanga bishikamye: Ivyumba vyacu vy’ubuhinga (bifise ubushobozi bwo gukora amatoni 5.000 ku mwaka) biratuma ivyo bikoresho bishikirizwa ku gihe, mbere no ku vyo umuntu asaba vyinshi (ingoma z’ibiro 20-500).
Infashanyo y’ubuhinga: Ishirahamwe ryacu ry’abahinga mu vy’imiti ritanga impanuro imbere y’ugucuruza (nk’akarorero, guhuza ibisabwa) n’infashanyo inyuma y’ugucuruza (nk’akarorero, gutorera umuti ingorane zo gutunganya).
Uguhingura ibintu bibungabunga ibidukikije: Uburyo dukora buragabanya amazi mabi n’ibidukikije, bikaba bihuye n’intumbero z’ubuzima buramba kw’isi yose.
