Emva kokuba ilaphu lomqhaphu liphathwe ngesisombululo se-caustic soda, i-wax, igrisi, isitashi kunye nezinye izinto ... -
Global PVC imfuno recovery kuxhomekeke China.
Ukungena ngo-2023, ngenxa yemfuno ecothayo kwimimandla eyahlukeneyo, imakethi yehlabathi ye-polyvinyl chloride (PVC) isajongene nokungaqiniseki. Ngexesha elininzi le-2022, amaxabiso e-PVC e-Asia nase-United States abonise ukuhla ngokukhawuleza kwaye aphantsi ngaphambi kokungena kwi-2023. Ukungena kwi-2023, phakathi kwemimandla eyahlukeneyo, emva kokuba i-China ilungelelanise imigaqo-nkqubo yokuthintela kunye nokulawula ubhubhane, imarike ilindele ukuphendula; I-United States inokunyusa ngakumbi amaxabiso enzala ukuze kuliwe nokunyuka kwamaxabiso kunye nokunqanda imfuno yasekhaya yePVC eMelika. I-Asiya, ekhokelwa yi-China, kunye ne-United States ziye zandisa ukuthunyelwa kwe-PVC ngaphandle kwemfuno ebuthathaka yehlabathi. Ngokuphathelele iYurophu, ummandla usazokujongana nengxaki yamaxabiso aphezulu amandla kunye nokuhla kwamandla emali, kwaye mhlawumbi akuyi kubakho ukubuyiswa okuzinzileyo kwimida yenzuzo yoshishino. ... -
Iyintoni impembelelo yenyikima enamandla eTurkey kwi-polyethylene?
ITurkey lilizwe elijikeleze iAsia kunye neYurophu. Ityebile kwimithombo yamaminerali, igolide, amalahle kunye nezinye izixhobo, kodwa ayinayo i-oyile kunye negesi yendalo. Ngo-18:24 ngoFebruwari 6, ixesha laseBeijing (13:24 ngoFebruwari 6, ixesha lendawo), inyikima ye-7.8 yenzeke eTurkey, kunye nobunzulu obunzulu beekhilomitha ezingama-20 kunye ne-epicenter kwi-38.00 degrees latitude emntla kunye ne-37.15 degrees empumalanga. Le ntlekele yayikumazantsi eTurkey, kufutshane nomda waseSyria. Awona mazibuko aphambili kwesi siganeko neendawo eziyingqongileyo yayiyiCeyhan (eCeyhan), i-Isdemir (i-Isdemir), neYumurtalik (Yumurtalik). I-Turkey ne-China zinobudlelwane bexesha elide lokurhweba ngeplastiki. Ukuthathwa kwelizwe lam kwepolyethylene yaseTurkey incinci kwaye iyancipha unyaka nonyaka, kodwa umthamo wokuthumela ngaphandle ngokuthe ngcembe... -
Uhlalutyo lwemakethi ye-Caustic soda ethumela ngaphandle ngo-2022.
Ngo-2022, imakethi yelizwe lam yolwelo lwe-caustic ye-soda yokuthumela ngaphandle iyonke iya kubonisa umkhwa oguquguqukayo, kwaye unikezelo lokuthumela ngaphandle luya kufikelela kwinqanaba eliphezulu ngoMeyi, malunga ne-750 yeedola zaseMelika ngetoni, kwaye umyinge wonyaka wokuthumela ngaphandle umthamo wenyanga uya kuba ziitoni ezingama-210,000. Ukwanda okumandla komthamo wokuthumela ngaphandle kwesoda yolwelo lwe-caustic soda ikakhulu ngenxa yokwanda kwemfuno esezantsi yomlambo kumazwe afana ne-Australia ne-Indonesia, ngakumbi ukugunyaziswa kweprojekthi ye-alumina esezantsi e-Indonesia kuye kwanyusa imfuno yokuthengwa kwe-caustic soda; ukongeza, uchatshazelwa ngamaxabiso ombane wamazwe ngamazwe, izityalo ze-chlor-alkali zasekhaya eYurophu ziqalise ukwakhiwa Akwanelanga, ukunikezelwa kwesoda ye-caustic engamanzi kuncitshisiwe, ngaloo ndlela ukwandisa ukungeniswa kwe-caustic soda kuya kwenza kwakhona i-suppo enhle ...
