Eminyakeni yamuva, imboni ye-polyethylene yaseShayina igcine umfutho oqinile wentuthuko, izinga lokukhula komkhiqizo nokusetshenziswa lihamba phambili emhlabeni.Ngesikhathi esifanayo, i-China isengumthengisi omkhulu we-polyethylene emhlabeni wonke.Kodwa-ke, kanye nokuthuthukiswa okusheshayo kwemboni, ukungqubuzana kwesakhiwo kuye kwavela kancane kancane, njengokweqile kwemikhiqizo ephakathi nendawo kanye nesezingeni eliphansi, ukuncintisana okukhulu kwe-homogeneous, kanye nesimo esibucayi sokulahlekelwa kweyunithi.Ngakho-ke, kuyindlela eyinhloko yempumelelo yemboni ukukhuthaza ukuthuthukiswa kwesakhiwo somkhiqizo wemikhiqizo ye-polyethylene futhi ibone ubuchwepheshe bomkhiqizo, ukuhlukanisa, ukuphela okuphezulu, okuluhlaza kanye nokwenza ngokwezifiso.Kuphinde kube yinto ebalulekile ukuthi amabhizinisi abambe ithuba ngaphansi kokuncintisana okunamandla embonini yesikhathi esizayo.
Njengamanje, i-polyethylene isetshenziswa ikakhulukazi emikhakheni emi-5 elandelayo, ifilimu, ukubumba umjovo, okungenalutho nokudweba, ipayipi.Ngokuthuthukiswa kwensimu eyonakalayo, i-polyethylene ibophezelekile ukuthatha isabelo esithile semakethe, kuyilapho ezinye i-UHMWPE, MLLDPE, EVA kanye ne-POE elastomers zizonikeza izinzuzo zemikhiqizo emikhakheni emihlanu, njenge-high-end lithium battery diaphragm, photovoltaic packaging film. , i-ejenti yokupakisha ye-photovoltaic kanye nefilimu yokupakisha yasensimini ephezulu kanye nezicelo zensimu yezempi yaseMarine.
Ngo-2022, amandla okukhiqiza enziwe nge-polyethylene e-China azokhuphuka afinyelele kumathani ayizigidi ezingama-29.81/ngonyaka, ngesilinganiso sokukhula saminyaka yonke esingu-12.32%, futhi azogcina izinga lokunwetshwa kwesivinini esikhulu esingu-12% eminyakeni emihlanu ezayo.Ngakho-ke, ukuthuthukiswa kwesakhiwo somkhiqizo kuwumkhuba weThe Times.Amabhizinisi asekhaya okukhiqiza i-polyethylene ahlukaniswe abeI-HDPE, I-LDPEkanye ne-DFPE izinhlobo ezintathu zamadivayisi, amadivayisi amathathu angenhla ahlanganisa u-44%, 16% no-40% wesamba somthamo ngokulandelanayo.Njengamanje, ngokuthuthuka okusheshayo kwemboni ye-polyethylene yaseChina, ukuze kuxazululwe ukungqubuzana kwesakhiwo "yemikhiqizo ephansi kakhulu kanye nokuntuleka kwemikhiqizo ephezulu", iphethini yezimboni izoshintsha ekuhlukaniseni nasekuphakameni okuphezulu.Ukuze ubambe imakethe yabathengi yesikhathi esizayo kusengaphambili, ubuchwepheshe bomkhiqizo, ukuhlukaniswa kanye nokuphela okuphezulu kuseduze.
Njengamanje, kunezinhlobo ezintathu zemikhiqizo yepulasitiki ephezulu engakhiqizwa ezindaweni zokukhiqiza zangempela zebhizinisi, okungukuthi i-MLLDPE (i-metallocene polyethylene), i-UHMWPE (i-ultra-high molecular weight polyethylene) ne-EVA;I-POE elastomer kanye nemikhiqizo yepulasitiki eyonakalayo idinga ukukhiqizwa ngomshini omusha.Lezi zinhlobo ezinhlanu zemikhiqizo zingezezinhlobo zepulasitiki ezisezingeni eliphezulu ezinamanani aphezulu, inzuzo ecebile namathemba abanzi.Iqhutshwa umgomo wamasu "we-carbon double" nezinqubomgomo zokuvikela imvelo, i-China, njengomthengi omkhulu, izosebenzisa umoya wasempumalanga wenqubomgomo, ngamandla angenamkhawulo kanye nekusasa elithembisayo.
