    Ku saabsan Codsiga Thiourea1

    Thiourea, oo leh qaacidada molecular ee (NH2)2CS, waa orthorhombic cad ama kiristaalo dhalaalaya.Hababka warshadaha ee diyaarinta thiourea waxaa ka mid ah habka amine thiocyanate, habka nitrogen lime, habka urea, iwm. Habka nitrogen lime, nitrogen lime, gaaska hydrogen sulfide iyo biyaha ayaa loo isticmaalaa hydrolysis, falcelinta dheeraadka ah, sifaynta, crystallization iyo qalajinta ee synthesis. kilsi si aad u hesho alaabta dhammaatay.Habkani wuxuu leeyahay faa'iidooyinka socodka gaaban ee geeddi-socodka, wax wasakh ah, qiimo jaban iyo tayada alaabta wanaagsan.Waqtigan xaadirka ah, badi warshaduhu waxay qaataan habka nitrogen-ka lime si ay u diyaariyaan thiourea.
    Marka la eego xaaladda suuqa, Shiinuhu waa wax soo saarka thiourea ugu weyn adduunka.Marka laga soo tago buuxinta baahida gudaha, wax soo saarkeeda ayaa sidoo kale loo dhoofiyaa Japan, Yurub, Mareykanka, Koonfur-bari Aasiya iyo wadamo iyo gobollo kale.Marka la eego codsiga hoose, thiourea waxaa si weyn loogu isticmaalaa sida alaabada ceyriinka ah ee lagu soo saaro sunta cayayaanka, daawooyinka, kiimikooyinka elektiroonigga ah, waxyaabaha lagu daro kiimikada, iyo sidoo kale wakiilka sabbeynta dahabka.

    Sanadihii ugu dambeeyay, wax soo saarka thiourea ee Shiinaha ayaa horumaray ilaa xad, iyada oo awood ah 80,000 tan / sannadkii iyo in ka badan 20 warshadood, kuwaas oo in ka badan 90% ay yihiin soosaarayaasha milixda barium.

    Japan, waxaa jira 3 shirkadood oo soo saara thiourea.Sanadihii la soo dhaafay, sababtoo ah xaalufka macdanta, kororka kharashka tamarta, wasakhowga deegaanka iyo sababo kale, wax soo saarka barium carbonate ayaa hoos u dhacay sanadba sanadka ka dambeeya, taasoo keentay hoos u dhaca wax soo saarka hydrogen sulfide, kaas oo xaddidaya wax soo saarka thiourea.In kasta oo baahida suuqa ay si degdeg ah u korodhay, awoodda wax-soo-saarka ayaa si aad ah hoos loogu dhigay.Wax-soo-saarku waa qiyaastii 3000 oo tan / sannadkii, halka baahida suuqyadu ay ku dhowdahay 6000 tan / sannadkii, farqiga u dhexeeyana waxaa laga keenaa Shiinaha.Waxaa jira laba shirkadood oo Yurub ah, Shirkadda SKW ee Jarmalka iyo Shirkadda SNP ee Faransiiska, iyada oo wadarta wax soo saarka 10,000 tan sannadkii.Iyadoo horumarinta joogtada ah ee thiourea ee sunta cayayaanka iyo isticmaalka kale ee cusub, Nederland iyo Belgium waxay noqdeen macaamiisha thiourea.Isticmaalka suuqa sannadlaha ah ee suuqa Yurub waa qiyaastii 30,000 tan, kuwaas oo 20,000 oo tan ka mid ah loo baahan yahay in laga keeno Shiinaha.Shirkadda ROBECO ee dalka Maraykanka waxa ay soo saartaa thiourea sannadkii oo dhan ilaa 10,000 oo tan/sannadkii, laakiin ilaalinta deegaanka oo sii kordheysa awgeed, wax-soo-saarka thiourea ayaa sannadba sannadka ka dambeeya hoos u dhacaya, kaas oo ka fog daboolaya baahida suuqa.Waxay u baahan tahay inay Shiinaha ka soo dhoofsato in ka badan 5,000 tan oo thiourea ah sannad kasta, inta badan loo isticmaalo sunta cayayaanka, daawooyinka iyo beeraha kale.
