Umbiko Wemakethe we-Polypropylene (PP) kanye ne-Polyethylene (PE)

Ukugxila Okuyinhloko

I-US ne-Iran basayine isivumelwano sokusebenzisana kude, bavula iwindi lezingxoxo zezinsuku ezingama-60. I-US ithembise ukususa izivimbelo zasemanzini zingakapheli izinsuku ezingama-30, kuyilapho i-Iran izoxoxisana ngokuphathwa kwemigwaqo eqondile ne-Oman. Kodwa-ke, amasosha ase-US aqala iziteleka ngosuku olufanayo, izinhlangothi zombili zisolana ngokwephula isivumelwano. USomlomo wePhalamende lase-Iran uthe lo mgwaqo "ngeke ubuyele esimweni sawo sangaphambili". Abahlaziyi baphawule ngokuthi ukusayinwa kwale memorandamu kuphawula intuthuko enkulu, kodwa umbono wokuqaliswa kwayo usalokhu ungaqinisekile, futhi ithemba lemakethe ngezingxoxo zokuthula kufanele liphathwe ngokucophelela.

Ukunikezwa kwe-PP

Izinga lokusebenza kwezitshalo ze-PP pellet limi ku-66.25% (okungaguquki isonto nesonto), kanti elezitshalo ze-PP powder lifinyelele ku-26.56% (okungaguquki isonto nesonto). Inani eliphelele lempahla ye-PP lilokhu lehla. Umugqa wokuqala we-Zhongjing Phase I (amathani angu-500,000 ngonyaka) uhlelelwe ukuqala kabusha ngoMgqibelo, kanti umugqa wesibili (amathani angu-500,000 ngonyaka) uzoqala ukusebenza ngoLwesithathu oluzayo. Izikhungo ze-PP ze-Yan'an Refinery kanye ne-Yan'an Energy & Chemical zizolungiswa ngesonto elizayo. Izindali zokuthengisa amalahle zibe ngamakhemikhali zibone ukuthengiswa okunamandla, kanti wonke ama-PP adonswa ngocingo aphelele. Isikhungo esisha samathani angu-450,000 ngonyaka eDushanzi Tarim siqede ukudla okuvivinywayo futhi sizosebenza ngokugcwele maphakathi nenyanga.

Ukunikezwa kwe-PE

Izinga lokusebenza le-PE lilonke lifinyelele ku-77.59%. Izitolimende kubakhiqizi be-PE zaqhubeka nokukhula, futhi izitolimende zabadayisi zanda. Izinga lokusebenza elimaphakathi lamabhizinisi angaphansi komfula lalingu-34.31%. Intengo ye-7042 LLDPE evela eNyakatho China Petrochemical eLinyi ime ku-8,300 yuan/ton, ikhuphuke ngo-50 yuan/ton. Amanani e-LLDPE eMpumalanga China aguquguquka ngaphakathi kwebanga lama-yuan angu-50/ton. I-LDPE yahlala iyinzuzo ephezulu ngokunyuka kwentengo okuncishisiwe, kuyilapho amanani e-HDPE ahlala eqinile.

Isidingo

Izinga lokusebenza eliphansi le-PP lalingu-45.52%. Isikhathi sokungasebenzi saqhubeka ngezikhwama zepulasitiki ezilukiwe, amafilimu e-BOPP kanye nemikhakha yokubumba injection esetshenziswa nsuku zonke. Izinga lokusebenza eliphansi le-PE lehle ngo-0.47% inyanga nenyanga. Ngenxa yokulindela ukwenyuka kwentengo, ukuthengwa kwezidingo eziqinile kwanda kancane, kodwa ukuphinda kufakwe izinto kabusha kwaba yisixwayiso phakathi kwamanani aphezulu. Abakhiqizi abaphansi babonise ukumelana okukhulayo namazinga entengo yamanje.

Inzuzo Ephansi

Inzuzo enkulu yamalahle kuya ku-PP ifinyelele ku-1,520 yuan ngethani (izinga lenzuzo ephezulu). I-PP esekelwe ku-PDH iqophe ukulahlekelwa okungu-252.62 yuan ngethani, kanti i-PP ekhiqizwe nge-propylene ethengwe ngaphandle ilahlekelwe ngu-409.43 yuan ngethani. I-Oil-to-PE ilahlekelwe ngu-675 yuan ngethani, kanti i-coal-to-PE igcine inzuzo engu-1,182 yuan ngethani. Intengo ye-propylene eShandong ibambeke ezingeni eliphezulu lama-yuan angu-9,000 ngethani. Inzuzo ephezulu yemizila esekelwe kumalahle yakhulisa ukuzimisela kokukhiqiza, kanti i-PDH kanye nemizila yokukhiqiza esekelwe kumalahle yahlala ingaphansi kwengcindezi eqhubekayo.
