Thiourea, nrog cov mis molecular ntawm (NH2) 2CS, yog dawb orthorhombic lossis acicular ci siv lead ua.Cov txheej txheem kev lag luam rau kev npaj thiourea muaj xws li amine thiocyanate txoj kev, txiv qaub nitrogen txoj kev, urea txoj kev, thiab lwm yam nyob rau hauv cov txiv qaub nitrogen txoj kev, txiv qaub nitrogen, hydrogen sulfide roj thiab dej yog siv rau hydrolysis, ntxiv cov tshuaj tiv thaiv, pom, crystallization thiab ziab nyob rau hauv lub synthesis. kettle kom tau cov khoom tiav.Txoj kev no muaj qhov zoo ntawm cov txheej txheem luv luv, tsis muaj kuab paug, tsis muaj nqi thiab cov khoom zoo.Tam sim no, feem ntau ntawm cov chaw tsim khoom siv cov kua qaub nitrogen los npaj thiourea.
Los ntawm cov xwm txheej kev ua lag luam, Tuam Tshoj yog tus tsim khoom loj tshaj plaws thiourea hauv ntiaj teb.Ntxiv rau qhov ua tau raws li qhov xav tau hauv tsev, nws cov khoom tseem raug xa tawm mus rau Nyiv, Tebchaws Europe, Tebchaws Meskas, Sab Qab Teb Asia thiab lwm lub tebchaws thiab cheeb tsam.Nyob rau hauv cov nqe lus ntawm downstream daim ntawv thov, thiourea yog dav siv los ua raw khoom rau kev tsim tshuaj tua kab, tshuaj, hluav taws xob tshuaj, tshuaj additives, raws li zoo raws li kub flotation tus neeg saib xyuas.
Nyob rau hauv xyoo tas los no, thiourea ntau lawm nyob rau hauv Tuam Tshoj tau tsim rau ib qho twg, muaj peev xwm ntawm 80,000 tons / xyoo thiab ntau tshaj 20 manufacturers, ntawm uas ntau tshaj 90% yog barium ntsev manufacturers.
Hauv Nyij Pooj, muaj 3 lub tuam txhab tsim thiourea.Nyob rau hauv xyoo tas los no, vim yog depletion ntawm ore, qhov nce ntawm cov nqi hluav taws xob, ib puag ncig muaj kuab paug thiab lwm yam laj thawj, cov khoom tsim tawm ntawm barium carbonate tau poob qis ib xyoos ib zaug, ua rau txo qis ntawm kev tsim cov hydrogen sulfide, uas txwv kev tsim cov khoom ntawm hydrogen sulfide. Thiourea.Txawm hais tias muaj kev loj hlob sai ntawm kev lag luam kev xav tau, lub peev xwm ntau lawm tau txo qis.Cov zis yog li 3000 tons / xyoo, thaum lub lag luam xav tau nyob ib ncig ntawm 6000 tons / xyoo, thiab qhov sib txawv yog imported los ntawm Tuam Tshoj.Muaj ob lub tuam txhab nyob sab Europe, SKW Tuam Txhab hauv Tebchaws Yelemees thiab SNP Tuam Txhab hauv Fab Kis, nrog rau tag nrho cov khoom tsim tawm ntawm 10,000 tons hauv ib xyoos.Nrog kev txhim kho txuas ntxiv ntawm thiourea hauv tshuaj tua kab thiab lwm yam kev siv tshiab, Lub Netherlands thiab Belgium tau dhau los ua cov neeg siv khoom loj ntawm thiourea.Kev lag luam txhua xyoo hauv European kev lag luam yog kwv yees li 30,000 tons, ntawm 20,000 tons yuav tsum tau xa los ntawm Tuam Tshoj.ROBECO lub tuam txhab hauv Tebchaws Meskas muaj cov khoom tsim tawm txhua xyoo ntawm thiourea txog 10,000 tons / xyoo, tab sis vim muaj kev tiv thaiv ib puag ncig nruj zuj zus, cov khoom tsim tawm ntawm thiourea txo qis xyoo los ntawm xyoo, uas yog deb ntawm kev ua lag luam xav tau.Nws yuav tsum tau import ntau tshaj 5,000 tons ntawm thiourea los ntawm Tuam Tshoj txhua xyoo, feem ntau yog siv tshuaj tua kab, tshuaj thiab lwm yam teb.
