Faa'iidada warshadaha caprolactam wanaagsan waxay bilaabeen inay sii wadaan heer sare

Petrochemical, Haili, Qinghua baarkinka. Cangzhou Xuyang wejiga I wax soo saarka ayaa dib u bilaabmay, Yongrong asal ahaan waa buuxaa, dayactirka Sanning wax yar ayaa dib loo dhigay, culeyska caprolactam ayaa la filayaa inuu sii ahaado mid sareeya mustaqbalka dhow, iyo sahayda wax soo saarka ammonium sulfate ayaa kordhin doonta si waafaqsan.

Saddexda wareeg ee kororka kookaha ayaa xaddidan

Dhowaan, muunadda buuxda ee shirkadaha kookaha ee madaxa-bannaan ee Shiinaha: heerka isticmaalka awoodda wuxuu ahaa 73.3%, hoos 0.5% marka loo eego xilligii hore. Waqtigan xaadirka ah, suuqa kookaha ayaa si xooggan u socda. Kookaha wareegii saddexaad ee kor u kaca iyo hoos u dhaca, korodhka xawliga ah ee ku yimid qiimaha dhuxusha, jawiga ganacsi oo kulul, dhaqdhaqaaqa suuqa ayaa aad u kordhay, cadaadiska qiimaha shirkadaha kookaha ayaa kordhay, inta badan shirkadaha kookaha ayaa leh khasaare, iyo qaar la filayo in la yareeyo wax soo saarka.

Waqtigan xaadirka ah, sahayda ammonium sulfate ee labada geeddi-socod ee ugu muhiimsan ee ammonium sulfate ee Shiinaha waa mid deggan, in kasta oo bilawga ganacsiga kookaha uu hoos u dhacay wax yar, laakiin bilawga shirkadaha caprolactam ayaa sii waday heer sare, iyo sahayda wada-shaqeynta. wax soo saarka ammonium sulfate ayaa kordhay. Dhinaca baahida, qiimaha urea ee caalamiga ah ayaa kor u kacay, oo ay weheliso Hindiya isla markiiba waxay sii daayeen wareeg cusub oo ah wararka tartanka HOL, iyo sidoo kale mustaqbalka kor u kaca dareenka, qiimaha dhibcaha ayaa kor u kacay, kor u qaadaya maskaxda warshadaha, iyo xamaasadda weydiinta ganacsatadu waa mid wanaagsan. Marka la eego ganacsiga gudaha, heerka isticmaalka ee awoodda bacriminta isku dhafan ayaa sii socota inay korodho, laga bilaabo meelaha caadiga ah, oo ay ku jiraan gobolka Hubei, shirkadaha waaweyn ee waaweyn ee horay u sii socda, si loo hubiyo sahayda, heerka hawlgalka ayaa si weyn u kordhay. Waqtigan xaadirka ah, baahida goobta ayaa ah mid wanaagsan, taageerta hawlgalka ammonium sulfate ee heer sare ah. Iyadoo la tixgelinayo in ka dib kor u kaca joogtada ah, dhibaatada qaar ka mid ah soosaarayaasha hoose si ay ula socdaan waa ay korodhay, waxaa la filayaa in muddada gaaban ee ammonium sulfate suuqa inta badan uu sarreeyo oo cidhiidhi ah, iyo in fiiro gaar ah la siiyo xaaladda nidaamka suuqa caalamiga ah.
