Kusukela ngo-2020, izitshalo ezifuywayo ze-polyethylene zingene emjikelezweni wokwandisa ophakathi nendawo, futhi umthamo wonyaka wokukhiqiza we-PE yasekhaya ukhule ngokushesha, ngesilinganiso sokukhula sonyaka esingaphezu kwe-10%.Ukukhiqizwa kwe-polyethylene ekhiqizwa ekhaya kuye kwanda ngokushesha, nge-homogenization yomkhiqizo onzima kanye nokuncintisana okunamandla emakethe ye-polyethylene.Yize isidingo se-polyethylene siphinde sakhombisa ukuthambekela kokukhula eminyakeni yamuva nje, ukukhula kwesidingo akubanga ngokushesha njengezinga lokukhula kokuhlinzekwa.Kusukela ngo-2017 kuya ku-2020, amandla amasha okukhiqiza e-polyethylene yasekhaya agxile kakhulu ezinhlobonhlobo ze-voltage ephansi kanye ne-linear, futhi kwakungekho mishini yamandla kagesi aphezulu asetshenziswe e-China, okuholele ekusebenzeni okuqinile emakethe yamandla kagesi aphezulu.Ngo-2020, njengoba umehluko wamanani phakathi kwe-LDPE ne-LLDPE ukhula kancane kancane, ukunaka kwemikhiqizo ye-LDPE kukhule.Iyunithi yokukhiqiza ehlangene ye-EVA kanye neyunithi ye-Zhejiang Petrochemical LDPE yaqala ukusebenza ngo-2022, inamandla okukhiqiza asekhaya anengcindezi ephezulu engamathani ayizigidi ezingu-3.335 kusukela ngosuku olwedlule.
Ngo-2023, imakethe enengcindezi ephezulu yakhombisa ukuguquguquka nokwehla.Uma sithatha imakethe yaseNyakatho yeShayina njengesibonelo, inani lentengo eliphakathi kwengcindezi ephezulu kusukela ngoJanuwari kuya kuMeyi lalingu-8853 yuan/ton, ukwehla okuphawulekayo konyaka ngo-24.24%.Esikhathini esiphezulu sokufunwa kwefilimu yepulasitiki engxenyeni yokuqala, amanani entengo abenamandla uma kuqhathaniswa.Isilinganiso senani lentengo kusukela ngoJanuwari kuya ku-April sasingu-8273, ukwehla konyaka nonyaka ngo-7.42%.Umehluko wamanani phakathi kwamandla kagesi aphezulu kanye nomugqa wehliswe kakhulu.Kusukela ngomhlaka-23 Meyi, umugqa ojwayelekile wasekhaya emakethe yaseNyakatho neChina wawungu-7700-7950 yuan/ton, kanti ifilimu evamile yasekhaya enengcindezi ephezulu yabikwa ku-8000-8200 yuan/ton.Umehluko wamanani phakathi kwamandla kagesi aphezulu kanye ne-linear wawungu-250-300 yuan/ton.
Sekukonke, ngokwanda okuqhubekayo kwamandla okukhiqiza i-polyethylene yasekhaya kanye nokwanda kancane kancane kokuhlinzekwa kwasekhaya, inkinga yokutholakala ngokweqile embonini ye-polyethylene iye yanda.Nakuba izindleko zokukhiqiza zamandla kagesi aphezulu ziphakeme kancane kunomugqa, ngenxa yokushintshwa kwe-linear ne-metallocene kwezinye izindawo zokukhiqiza, kunzima ukusekela amanani aphezulu kanye nenzuzo ephezulu emakethe ye-polyethylene ebuthakathaka yamanje, kanye nomehluko wamanani phakathi kwamandla kagesi aphezulu. futhi umugqa unciphe kakhulu.
