Tic ma rwate
Kit ma Thiourea tye kwede ma pat (me labolle, kero me yubu jami ma rwate ki jami ma ki yubu ki cuma, tic calo gin ma dwoko piny, ki nywako i yubu jami ma pat pat) miyo en bedo gin ma pire tek i tic mapol:
3.1 Tic me yubu jami ki nyonyo
Yubu jami ma ki yubu ki nyonyo: Ki tiyo kwede ma calo gin ma weko jabu ki ryal bedo tek (me labolle, i kwanyo jabu ma pe ki cyanide) me kwanyo jabu ma piire tek ki i got. Tii calo gin ma ryeny ki ma gwoko jami ma ki lwongo ni nickel, copper, ki zinc electroplating, ma weko rangi del kom bedo marom ki ryeny.
Gengo balo: Ki medo i kom jami ma ngiic, jami ma ki tiyo kwede me buru, ki pii ma ki tiyo kwede me yubu jami ma gwoko kom i kom cuma, ma gengo balo ki acid.
3.2 Yub me jami ma ki lwongo ni Chemical Synthesis
Yat & Agrochemicals: Gin ma pire tek i yubu sulfonamides (yadi ma neko kwidi two), thyroid hormones, ki yat ma neko lum (me labolle, yat ma neko lum ma ki yubu ki thiourea pi juku lum i poto).
Yub me rangi ki rangi: Ki tiyo kwede me yubu jami ma ki lwongo ni thiazole ki imidazole, ma obedo jami ma pire tek i rangi ma ki lwongo ni azo dyes ki organic pigments (me labolle, pi bongo, plastik, ki ink).
Tic me rubber: tiyo calo gin ma weko rubber dongo oyoto ki loko, medo teko pa rubber, gengo lyeto, ki gengo dongo i taya, jami ma ki umu, ki jami ma ki yubu ki rubber.
3.3 Tic ki ot yat ki jami ma pat pat
Analytical Chemistry: Ki tiyo kwede me nongo ki kwano wel jami ma pek (e.g., 铋、selenium) kun kitiyo ki jami ma rwate.
Goyo cal: tiyo calo gin ma dwoko piny ki gin ma dwoko piny i mako cal macol ki tar, konyo me gwoko cal ki kwanyo silver halides ma pe nen.
Gwok ki lubu cik
4.1 Cik me gwoko kwo
Kit me tic kwede: Kur yweyo buru onyo mako del kom/wang. Ruk gilaci ma gengo buru, gloves ma ki yubu ki nitrile, ki gin ma umu yamo (N95 onyo ma malo) kama yamo pe donyo iye maber. Lwok cing maber ki cabun ki pii inge mako cing.
Ka gwoko: Gwok kama ngiic, ma otwo, ki kama yamo kato iye maber mabor ki acid ma tek (me labolle, acid ma ki lwongo ni hydrochloric acid), jami ma kelo yamo (me labolle, hydrogen peroxide), ki mac ma lyel. Tii ki HDPE ma ki umu onyo fiber drums me gengo pii ki balo ne.
Bolo: Bolo yugi onyo thiourea ma pi kitiyo kwede malube ki cik me gwoko kwo pa dano (me labolle, ma calo yugi ma pe kelo peko; kur me bolo ne i ngom onyo pii).
4.2 Lubu cik
Lubu cik me REACH (EU) (ma ki coyo i te REACH SVHC list, pe ki gengo tic kwede i gang tic).
rwate ki cik pa FDA (pi jami ma mako cam, ma calo, ma gengo balo jami ma ki tiyo kwede me yubu cam).
Ma lubu cik pa USP/NF (rwom me yat) me tic kwede i yubu yat.
Ki moko ki ISO 9001 (gwoko rwom) ki ISO 14001 (gwoko kabedo) pi yub me yubu jami.
Karatac me ngec ma mako tic (TDS) ma pire tek
| Parameter | rwom me tic | rwom me yat | Yo me temo |
| Lengo | ≥99.0% | ≥99.5% | Gin ma ki lwongo ni High - Performance Liquid Chromatography (HPLC) |
| Kit ma yamo tye kwede | ≤0.5% | ≤0.3% | Karl Fischer Titration |
| Gin ma tye iye | ≤0.1% | ≤0.05% | Gravimetric Analysis |
| Iron (Fe) | ≤5 ppm | ≤2 ppm | Atomic Absorption Spectroscopy (AAS) |
| Gin ma pe gony i pii | ≤0.01% | ≤0.005% | Kwanyo ki juku |
Pingo wa yero Thiourea wa?
Jami ma ki yubu pi ngat acel acel: Wa miiyo jami ma ki yubu me yubu jami, yadi, ki jami ma ki tiyo kwede i ot yat me cobo peko pa luwil (me labolle, jami ma pek manok ma ki tiyo kwede i ot yat).
Jami ma ki cwalo ma rwate: Kabedo wa me yubu jami (ki kero me 5,000 tons mwaka ki mwaka) miyo jami ma ki cwalo i kare ma opore, kadi wa pi jami mapol (20-500 kg drums).
Kony me tic: Dul pa ludiro wa miiyo tam ma peya ki cato wil (me labolle, rwate ki jami ma ki tiyo kwede) ki kony inge cato wil (me labolle, cobo peko me tic).
Yub ma pe balo kwo pa dano: Kit me yubu jami wa dwoko piny pii ma obale ki yamo ma ki cwalo woko, ma rwate ki yub me gwoko kwo pa dano i wilobo.
