Tic ma rwinyo
Kit pa Thiourea ma ukoc (e.g., copo mi yubu dul ku cuma, timo tic calu piny ma dwoko piny, man timo tic i heterocyclic synthesis) miyo ebedo piny ma pire tek i tic matung tung:
3.1 Tic mi cuma man cuma
Metal Refining & Plating: Jutiyo kudu calu piny ma nyayu peko i gold man silver (e.g., i gold ma epe ku cyanide) mi poko cuma mabec kud i ores. Tiyu calu piny ma nyayu ler man ma ketho piny bedo maber i nickel, copper, man zinc electroplating, ma medo bedo pa jamb kum ma leng man maleng.
Gengo lyethu: Jumedo i pii ma lyethu, pickling solutions, man pii mi tic ku cuma mi yubu filim ma gwoko iwi cuma, ma jwigo lyethu man acid.
3.2 Yub pa kemikol
Yath & Agrochemicals: Piny ma pire tek ikind yiku pa sulfonamides (yath ma jwigo kwidi), thyroid hormones, man herbicides (e.g., thiourea-based herbicides pi jwigo lum i podho).
Dye & Pigment Manufacturing: Jutiyo kudu pi yubu thiazole man imidazole, ma gitiye piny ma pire tek pa azo dyes man organic pigments (calu, pi bongo, plastik, man ink).
Tic mi rubber: Tiyu calu vulcanization accelerator man modifier, medo elasticity pa rubber, kero pa lyethu, man kero pa rubber i taya, seals, man piny ma juyubu ku rubber.
3.3 Tic mi ot yath & tic ma pire tek
Analytical Chemistry: Jutiyo kudu calu piny ma jutiyo kudu pi nwangu man pimo wel pa cuma ma pek (e.g., 铋、selenium) nikadhu kud i yik ma tek.

Gwok & Lubu cik
4.1 Cik mi gwoko kwo
Kite: Kur yuyu buru nyo mako adila/wang. Ruk wang ma jwigere ngo, gloves mi nitrile, man mask mi yuyu (N95 nyo malu) ikabedu ma yamu wok ungo maber. Lwok cingi maber ku sabun man pii ingey mako cingi.
Ka gwoko: Gwok i ot ma ngic, ma muthwo, ma yamo wok iye maber mabor ku acid matek (calu, hydrochloric acid), piny ma nyayu yamo (calu, hydrogen peroxide), man mac ma lyel. Ti ku HDPE ma jugwoko maber nyo fiber drums mi juku pii kud i pii man nyayu piny ma rac.
Keth: Keth piny ma rac nyo thiourea ma jutiyo kudu ngo nimakere ku cik mi kabedu (e.g., calu piny ma rac ma rac ungo; kud iwek i ngom nyo i pii).
4.2 Lubu cik
Lubu cik pa REACH (EU) (ma jugoro i thenge pa REACH SVHC, epe ku cik moko pi tic kudu i tic).
Urombo ku cik pa FDA (pi tic ma mako cam, calu, calu piny ma juku lyethu pa jam tic mi yubu cam).
Malube ku USP/NF Standards (pharmaceutical grade) pi tic kudu i yubu yath.
Juyike ku ISO 9001 (gwoko ber pa piny) man ISO 14001 (gwoko piny) pi yub mi yubu piny.

Pirango ma wayero Thiourea mwa?
Grades ma juyiko: Wamiyo grades mi tic, mi yath, man mi laboratory ni rombu ku yeny pa juruwil (e.g., piny ma pek ma nok pi tic mi yath).
Piny ma rwinyo: Kabedo mwa mi yubu piny (ku kero pa 5,000 tons kubang oro) ketho piny wok i sawa ma mitire, kadi pi wil madwong (20-500 kg drums).
Kony mi tic: Udul mwa mi chemistry miyo kony ma podi jucwalo ngo (e.g., rwate ku piny ma jutiyo kudu) man kony i ngei wil (calu, cobo peko mi tic).
Yubu piny ma ber pi kwo pa piny: Yore mwa mi yubu piny dwoko piny pii ma cido man yamo ma rac, ma rwate ku yik pa ngom zoo.
