Intshayelelo: Kutshanje, izityalo zasekhaya ze-ethylene glycol ziye zaguquka phakathi kokuqaliswa kwakhona koshishino lweekhemikhali zamalahle kunye nokuguqulwa kwemveliso edibeneyo.Utshintsho ekuqalisweni kwezityalo ezikhoyo zenze ukuba ibhalansi yokubonelela kunye nemfuno kwiimarike zitshintshe kwakhona kwixesha elizayo.
Ishishini leMichiza yamalahle-IziCwangciso ezininzi zokuqalisa kwakhona
Okwangoku, ixabiso lamalahle kumazibuko asekhaya liyaguquguquka malunga ne-1100. Ngokombono weenzuzo zoqoqosho, izityalo zemigodi yamalahle zasekhaya kunye nezangaphandle zisephantsi kwelahleko, kodwa ezinye izityalo zisenezicwangciso zokuqalisa kwakhona ngokusekelwe kwimbono yezixhobo.

Ukususela kwisicwangciso sesixhobo sangoku, izixhobo ezininzi eziye zavalwa kunyaka ophelileyo ngoku ziqaliswe ngokutsha nguHongsifang, uHuayi, uTianye, noTianying;Kwinqanaba lokugqibela, uHenan noGuanghui nabo banezicwangciso zokuqalisa kwakhona;Emva kokulungiswa ngokutsha ngoMatshi, uGuizhou Qianxi uceba ukuqalisa kwakhona ekuqaleni kuka-Epreli.Isicwangciso esikhoyo solondolozo sika-Epreli asibekwa kwindawo enye.Ukongeza kokunyuka komthwalo weyunithi ye-1.8 yezigidi zeetoni ze-Shaanxi Coal, isicwangciso sisonke sokuveliswa kweekhemikhali zamalahle ngo-Epreli kulindeleke ukuba sibe malunga neetoni ezingama-400000.
Udibaniso – ukuthathwa kwemali ngokuyinxenye, uguqulo oluyinxenye lusephantsi koqwalaselo
Ukuguqulwa kwendabuko kusekelwe ikakhulu kummiselo wemveliso ye-ethylene oxide / ethylene glycol.Ixabiso langoku le-ethylene oxide lijikeleze i-7200. Ngokombono wokuthelekisa ixabiso, inzuzo yezoqoqosho yokuvelisa i-ethylene oxide okwangoku iphezulu kune-ethylene glycol.Nangona kunjalo, ngenxa yokunciphisa ukugcinwa kwe-ethylene oxide kunye nemfuno ekhoyo ngoku ye-ejenti yokunciphisa amanzi, amaninzi amashishini afumana ukunyuka kwamaxabiso kwi-ethylene oxide kodwa ukuthengisa kuthintelekile.Ke ngoko, amathuba okunyusa imveliso ye-ethylene oxide ngokucinezela i-ethylene glycol kwinqanaba lokugqibela lezixhobo zenkqubo yemveli lincinci kakhulu.
Ngoyilo olwahlukeneyo lwezityalo ezinkulu zokusulungekiswa kunye neekhemikhali, ulungelelwaniso olongezelelekileyo lwenziwe ukulungiselela ukukhetha okusezantsi kwe-ethylene kwizityalo ezithathu eziphambili zasekhaya zokusulungekiswa kunye nezityalo ezihlanganisiweyo zeekhemikhali kwinqanaba lamva.Umzekelo, ukonyusa i-ethylene oxide ngelixa uzidibanisa ezantsi, ukongeza i-styrene, i-vinyl acetate, kunye nezinye iimveliso ukulinganisa ukusetyenziswa kwe-ethylene.Ngo-Epreli, ukucocwa kakhulu kunye nokugcinwa kwekhemikhali rhoqo, iZhejiang Petrochemical, kunye nokunciphisa umthwalo wesathelayithi ngokuthe ngcembe, kodwa iqondo elithile lokuqonda lisafuna ukucaciswa ngakumbi.
Ukwakhiwa kwezixhobo ezitsha kunokulibaziseka
umfanekiso
Okwangoku, iSanjiang kunye neYuneng Chemical zinokuqiniseka okuphezulu kokubeka izixhobo ezitsha kwimveliso;Amathuba okuba imveliso imiselwe ngokwesiseko emva kombindi wonyaka.Okwangoku akukho sicwangciso esicacileyo semveliso kwezinye izixhobo.
Ngokusekelwe kwiinguqu zangoku zecala lonikezelo kunye nezicwangciso zezityalo zexesha elizayo, kulindeleke ukuba imveliso yepolyester iya kuhlala izinzile ukusuka ngoMatshi ukuya ku-Epreli.Kulindeleke ukuba kusekho ukulindela ukuchithwa kwempahla kwimbono yokulinganisela kwentlalo, kodwa umda jikelele wokuchithwa kwempahla ulinganiselwe.
