Kev siv thiab kev siv

Cov khoom siv wildly siv hauv kev lag luam kws tshuaj, kev ua liaj ua teb, tshuaj lom neeg, kev lag luam metallurgical, roj av thiab lwm yam. Nws tseem yog cov khoom tseem ceeb rau kev tsim thiourea dioxide (CH1N2O2S).

Chaotropic tus neeg sawv cev; muaj zog denaturant. Ntxiv solubility thiab rov qab cov proteins

Siv rau hauv kev txiav txim siab ntawm bismuth.

Nyob rau hauv tsiaj kua nplaum liquifiers thiab nyiaj tarnish removers. Photograph fixing tus neeg saib xyuas thiab tshem tawm stains los ntawm negatives; kev tsim cov resins; vulcanization accelerator; reagent rau bismuth, selenite ions.

Thiourea yog siv nyob rau hauv kev tsim cov resins, raws li ib tug vulcanization accelerator, thiab raws li aphotographic kho tus neeg saib xyuas thiab tshem tawm los ntawm negatives.

Kev siv ntau tshaj plaws rau thiourea yog rau kev tsim cov thiourea dioxide (30%), hauv leaching ntawm kub thiab nyiaj ores (25%), hauv diazo cov ntaub ntawv (15%), thiab raws li ib tug catalyst nyob rau hauv lub synthesis ntawm fumaric acid (10%) (IARC 2001). Nws kuj tau siv rau hauv kev tsim thiab hloov kho cov khoom siv hluavtaws. Lwm yam kev siv ntawm thiourea yog raws li ib tug yees duab toning tus neeg sawv cev, nyob rau hauv cov plaub hau npaj, raws li ib tug drycleaning neeg sawv cev, nyob rau hauv lub synthesis ntawm kws tshuaj thiab tshuaj tua kab, boiler - dej kho, thiab raws li ib tug reagent rau bismuth thiab selenite ions. Nws kuj tau siv rau hauv textile thiab dyeing auxiliaries, nyob rau hauv zus tau tej cov tshuaj ntxuav tu (xws li, rau cov duab tso tsheb hlau luam thiab hlau nto feem ntau), rau engraving hlau nto, raws li ib tug isomerization catalyst nyob rau hauv kev hloov ntawm cov txiv neej rau fumaric acid, nyob rau hauv tooj liab- refining electrolysis, nyob rau hauv electroplating, thiab raws li ib tug antioxidant. Lwm yam kev siv tau suav nrog vulcanization accelerator, ib qho ntxiv rau slurry explosives, raws li ib tug viscosity stabilizer rau cov kev daws teeb meem polymer, thiab raws li lub zog tsis nyob rau hauv cov roj av extraction. Nws kuj yog siv los ua cov khoom siv ntawm cov neeg siv khoom siv nyiaj polishes (HPD 2009), thiab tau siv los tshem tawm cov mercury ntawm cov dej khib nyiab los ntawm chlorine -alkali electrolysis.
