Ingxelo yeMarike yePolypropylene (PP) kunye nePolyethylene (PE)

Ukugxila kwiNgqondo

I-US kunye ne-Iran zisayine isivumelwano sokusebenzisana kude, zivula ithuba leentsuku ezingama-60 zokuthethathethana. I-US ithembise ukuphelisa imiqobo yolwandle zingadlulanga iintsuku ezingama-30, ngelixa i-Iran iza kuthethathethana ngolawulo lwe-strait ne-Oman. Nangona kunjalo, umkhosi wase-US waqalisa ukuhlasela ngaloo mini inye, omabini amacala etyholana ngokwaphula isivumelwano. Isithethi sePalamente yase-Iran sithe i-strait "ayiyi kubuyela kwimeko yayo yangaphambili". Abahlalutyi baphawule ukuba ukutyikitywa kwesivumelwano kubonisa impumelelo enkulu, kodwa umbono wokuphunyezwa kwayo awuqinisekanga kakhulu, kwaye ithemba lemarike malunga neengxoxo zoxolo kufuneka liphathwe ngononophelo.

Ubonelelo lwePP

Izinga lokusebenza kwezityalo ze-PP pellet limi kwi-66.25% (iveki nganye), kwaye elo lezityalo ze-PP powder lifikelele kwi-26.56% (iveki nganye). Inani elipheleleyo lezinto ze-PP liqhubeke nokuhla. Umgca wokuqala we-Zhongjing Phase I (iitoni ezingama-500,000 ngonyaka) ucwangciselwe ukuqala kwakhona ngoMgqibelo, kwaye umgca wesibini (iitoni ezingama-500,000 ngonyaka) uza kuqalisa ukusebenza ngoLwesithathu oluzayo. Izakhiwo ze-PP zeYan'an Refinery kunye neYan'an Energy & Chemical ziza kulungiswa kwiveki ezayo. Iifandesi ze-Coal-to-chemical zibone intengiso enamandla, kwaye zonke ii-PP ezidweba ngocingo zithengisiwe ngokupheleleyo. Isakhiwo esitsha se-450,000 yeetoni ngonyaka eDushanzi Tarim sigqibezele ukutya okulingwayo kwaye siza kusebenza ngokupheleleyo phakathi enyangeni.

Ubonelelo lwe-PE

Izinga lokusebenza le-PE lilonke lifikelele kwi-77.59%. Iimpahla kubavelisi be-PE ziqhubekile nokukhula, kwaye iimpahla zabarhwebi zinyuke kakhulu. Izinga lokusebenza eliphakathi kwamashishini asezantsi yayiyi-34.31%. Ixabiso le-7042 LLDPE evela kwi-North China Petrochemical eLinyi limi kwi-8,300 yuan/ton, lenyuka nge-50 yuan/ton. Amaxabiso e-LLDPE eMpuma China aguquguquka ngaphakathi koluhlu lwe-50 yuan/ton. I-LDPE yahlala iyeyona inyuse kakhulu ngenxa yokunyuka kwamaxabiso okunciphileyo, ngelixa amaxabiso e-HDPE ahlala ezinzile.

Imfuno

Izinga lokusebenza elisezantsi le-PP yayiyi-45.52%. Ixesha elingasebenziyo liqhubekekile kwiingxowa zeplastiki ezilukiweyo, iifilimu ze-BOPP kunye namacandelo okubumba injection asetyenziswa imihla ngemihla. Izinga lokusebenza elisezantsi le-PE lehle nge-0.47% inyanga nenyanga. Ngenxa yokulindela ukunyuka kwamaxabiso, ukuthengwa kwemfuno eqinileyo kuye kwanda kancinci, kodwa ukuphinda kufakwe izinto kwakhona kuye kwaba lunonophelo phakathi kwamaxabiso aphezulu. Abavelisi abasezantsi babonise ukumelana okukhulayo namanqanaba amaxabiso angoku.

Iinzuzo zeMargins

Inzuzo iyonke ye-coal-to-PP ifikelele kwi-1,520 yuan ngetoni (inqanaba lenzuzo ephezulu). I-PP esekelwe kwi-PDH irekhode ilahleko ye-252.62 yuan ngetoni, kwaye i-PP eveliswe kwi-propylene ethengwe ngaphandle ilahlekelwe yi-409.43 yuan ngetoni. I-oil-to-PE ilahlekelwe yi-675 yuan ngetoni, ngelixa i-coal-to-PE igcine inzuzo ye-1,182 yuan ngetoni. Ixabiso le-propylene eShandong libambeke kwinqanaba eliphezulu le-9,000 yuan ngetoni. Inzuzo ephezulu yeendlela ezisekelwe kumalahle yonyuse ukuzimisela kwemveliso, ngelixa i-PDH kunye neendlela zemveliso ezisekelwe kumalahle zihlale ziphantsi koxinzelelo oluqhubekayo.
