iThiourea yinhlanganisela lebalulekile ye sulphur lephilako lenesakhiwo lesifana ne urea (ifaka esikhundleni se atom ye oksijini nge sulphur). Ikhombisa kusebenta kwemakhemikhali lokuhlukile, kwenta kutsi ibe yintfo leluhlata legucugucukako kanye nekwengeteka kuyoyonkhe imikhakha yetimboni, yekulima, kanye neyelabhorethri. Ngetimphahla leticinile letibonakalako kanye nekuphendvula lokulawulekako, ihlangabetana nemazinga lacinile ekhwalithi etimeni letehlukahlukene tekusebenta.
Timphahla letibalulekile & Tinzuzo
| Imphahla | Kucaciswa | Inzuzo lebalulekile |
| Liphuzu Lekuncibilika | 176 - 178°C (ibola ngetulu kwa 180°C) | Kusimama kwekushisa ngaphakatsi kwekushisa lokujwayelekile kwekucubungula, kugwema kubola ngaphambi kwesikhatsi |
| Inani le-pH (1% wesisombululo lesinemanti) | 6.0 - 7.5 | Neutral kuya esidi kancane, ihambisana ne substrates letiningi ngaphandle kwekubangela kugcola noma kungalingani kwe pH . |
| Kuhlanteka (imizuzu) | 99.0% (lizinga letimboni); 99.5% (lizinga lemitsi) | Kuhlanteka lokusezingeni leliphakeme kunciphisa kungcola lokungatsintsa kusebenta kwemkhicito noma kubangele kuphendvula lokuseceleni |
| Lokucuketfwe Ngensimbi Lesindzako (max) | 10 ppm (i-Pb, i-Cd, i-Hg lilonkhe) | Ihlangabetana nemazinga emvelo netekuphepha, ilungele kudla-kutsintsana noma ticelo letihlobene nemitsi |
| I-Hygroscopic | Low (umunya umswakama lomncane ngesikhatsi sekushisa ekamelweni) | Kulula kugcina nekuphatsa ngaphandle kwekuhlangana, kucinisekisa lizinga lelifanako ngekuhamba kwesikhatsi |
Ticelo letijwayelekile
Timphahla tekhemikhali letihlukile te Thiourea (sib., likhono lekwakha tintfo letiyinkimbinkimbi ngetinsimbi, kusebenta njengendlela yekunciphisa, kanye nekuhlanganyela ekuhlanganisweni kwe heterocyclic) kwenta kutsi kube yintfo ledzingekako etimbonini letiningi:
3.1 Timboni & Tinsimbi
Kucolisa Tinsimbi & Kufaka: Kusetjentiswa njengentfo leyinkimbinkimbi ekukhipheni igolide nesiliva (sib., ekukhipheni igolide lelite i-cyanide) kwentela kuncibilikisa tinsimbi letiligugu kusuka kuma ores. Isebenta njengekukhanya kanye nekusimamisa ku nickel, litfusi, kanye ne zinc electroplating, kwenta ncono kufana kwekugcobisa kanye nekucwebetela.
Kuvikela Kugcola: Kufakwa kuma coolants etimbonini, tisombululo tekupheka, kanye nemanti ekusebenta ngensimbi kwenta ifilimu levikelako etindzaweni tensimbi, kuvikela umhlwa kanye nekugcola kwe esidi.
3.2 Kuhlanganiswa kwemakhemikhali
Imitsi & Emakhemikhali ekulima: Indlela lebalulekile lesemkhatsini ekukhiciteni ema sulfonamides (imitsi lelwa nemagciwane), emahomoni e thyroid, kanye netibulala titjalo (sib., tibulala titjalo letisekelwe ku thiourea tekulawula likhula etitjalweni).
Kukhicita Idayi & Imibala: Isetjentiswa kuhlanganisa ithiazole kanye ne imidazole lesuselwa kuyo, lokutintfo letibalulekile temadayi e azo kanye nemibala yetilwane (sib., yetintfo tekugcoka, emapulasitiki, kanye netinki).
Imboni Yerabha: Isebenta njengekusheshisa kwe vulcanization kanye nekugucula, kwenta ncono kugucuka kwerabha, kumelana nekushisa, kanye nekumelana nekuguga emathayini, timphawu, kanye nemikhicito yerabha.
3.3 Kusetjentiswa Kwelabhorethri & Lokukhetsekile
Ikhemikhali Yekuhlatiya: Isetjentiswa njenge reagent kutfola kanye nekulinganisa tinsimbi letisindzako (sib., 铋、selenium) ngekwakheka lokuyinkimbinkimbi.
Kutsatsa titfombe: Kusebenta njengentfo yekulungisa kanye nendlela yekunciphisa ekutsatseni titfombe letimnyama naletimhlophe, kusita kusimamisa titfombe kanye nekususa ema halides esiliva langakabonakali.
Kuphepha & Kulandzela
4.1 Imihlahlandlela Yekuphepha
Kuphatsa: Gwema kuphefumula lutfuli noma kutsintsana ngco nesikhumba/emehlo. Gcoka tibuko letingangeni lutfuli, emagilavu e-nitrile, kanye nemaski ekuphefumula (N95 noma ngetulu) etindzaweni letingangenisi umoya kahle. Geza tandla kahle ngensipho nemanti ngemuva kwekutsintsana.
Kugcina: Gcina endzaweni lepholile, leyomile, lenemoya lokahle khashane ne esidi lenemandla (sib., i-hydrochloric acid), tintfo letifaka i-oksijini (sib., i-hydrogen peroxide), kanye nemalangabi lavulekile. Sebentisa iHDPE levaliwe noma tigubhu te fibre kuvikela kutsatsa umswakama kanye nekungcola.
Kulahla: Lahla imfucuza noma i-thiourea lengasetjentiswa ngekuhambisana nemitsetfo yendzawo yemvelo (sib., njengemfucuza longasiyo ingoti yetimboni; gwema kukhipha emhlabatsini noma emantini).
4.2 Kulandzela Umtsetfo
Ihambisana neMtsetfosivivinyo we-REACH (EU) (lobhalisiwe ngaphansi kweluhlu lwe-REACH SVHC, kute imikhawulo yekusetjentiswa etimbonini).
Ihlangabetana ne FDA Standards (yekusebentisa lokutsintsana nekudla, sibonelo, njengesivimbeli sekugcola emishinini yekucubungula kudla).
Ihambisana ne-USP/NF Standards (lizinga lemitsi) lekusetjentiswa ekuhlanganiseni tidzakamiva.
Icinisekisiwe yi ISO 9001 (kulawula lizinga) kanye ne ISO 14001 (kulawula imvelo) yetinchubo tekukhicita.
Liphepha Lemininingwane Yebuchwepheshe (TDS) Tintfo Letigcamile
| Ipharamitha | Libanga Letimboni | Libanga Lemitsi | Indlela Yekuhlola |
| Bumsulwa | ≥99.0% | ≥99.5% | Lokusetulu - Kusebenta Kwemanti (HPLC) |

Kungani Sikhetsa I-Thiourea Yetfu?
Emabanga Lakhetsiwe: Siniketa emabanga etimboni, emitsi, kanye nelabhorethri kuhlangabetana netidzingo letitsite temakhasimende (sib., lokucuketfwe kwensimbi lesindzako lephansi yekusetjentiswa kwemitsi).
Kuphakela Lokucinile: Tindzawo tetfu tekukhicita (letinemandla emnyaka emathani langu 5,000) ticinisekisa kuhanjiswa ngesikhatsi, ngisho nema oda lamaningi (20-500 kg drums).
Kusekelwa Kwebuchwepheshe: Licembu letfu lemakhemikhali liniketa kubonisana ngaphambi kwekutsengisa (sib., kuhambisana kwesicelo) kanye nekusekelwa ngemuva kwekutsengisa (sib., kucatulula tinkinga tetindzaba tekucubungula).
Kukhicita Lokungalimatsi Imvelo: Inchubo yetfu yekukhicita inciphisa emanti langcolile kanye nekukhishwa kwemfutfo, ngekuhambisana nemigomo yekusimama kwemhlaba wonkhe.
