1. Isishwankathelo semo yokusebenza iyonke

Ngo-2024, ukusebenza ngokubanzi komzi mveliso weekhemikhali waseTshayina akulunganga phantsi kweempembelelo zokusingqongileyo. Inqanaba lengeniso yamashishini emveliso liye lehla ngokubanzi, imiyalelo yamashishini orhwebo yehlile, kwaye noxinzelelo ekusebenzeni kwemarike lonyuke kakhulu. Iinkampani ezininzi zizama ukuphonononga iimarike zaphesheya ukuze zikhangele amathuba amatsha ophuhliso, kodwa imeko ekhoyo ngoku yemalike yehlabathi ibuthathaka kwaye ayibonelelanga ngesantya esaneleyo sokukhula. Ngokubanzi, ishishini lemichiza laseTshayina lijongene nemingeni ebalulekileyo.

I-2, Uhlalutyo lweSimo seNzuzo yeeMichiza ezininzi

Ukuze ufumane ukuqonda okunzulu kokusebenza kwemarike yekhemikhali yaseTshayina, uphando lwenziwe kwiintlobo ezingama-50 zeekhemikhali ezininzi, kwaye inqanaba lengeniso yengeniso yeshishini eliphakathi kunye nenqanaba lokutshintsha konyaka ukusuka ngoJanuwari ukuya kuSeptemba 2024 zahlalutywa. .

Ukusasazwa kweeMveliso zeNzuzo kunye neLahleko: Phakathi kweendidi ezingama-50 zeekhemikhali ezininzi, kukho iimveliso ezingama-31 kwimeko enengeniso, zibalelwa malunga ne-62%; Kukho iimveliso ezili-19 ezikwimeko yokwenziwa kwelahleko, zibalelwa malunga ne-38%. Oku kubonisa ukuba nangona uninzi lweemveliso zisenengeniso, umlinganiselo welahleko owenziweyo awunakungahoywa.

Unyaka ngonyaka utshintsho kwi-margin yenzuzo: Ukususela kumbono wonyaka wokutshintsha izinga lonyaka, umda wengeniso yeemveliso ze-32 unqabile, ubala i-64%; Umda wenzuzo yeemveliso ze-18 kuphela zonyuka unyaka nonyaka, zibalelwa kwi-36%. Oku kubonisa ukuba imeko iyonke kulo nyaka ibuthathaka kakhulu kunonyaka ophelileyo, kwaye nangona imida yenzuzo yeemveliso ezininzi isalungile, yehlile xa ithelekiswa nonyaka ophelileyo, ebonisa ukusebenza kakubi ngokubanzi.

3, Ulwabiwo lwamanqanaba omda wenzuzo

Umda wenzuzo yeemveliso ezinenzuzo: Inqanaba lomda wenzuzo yezona mveliso zinengeniso zigxininiswe kuluhlu lwe-10%, kunye nenani elincinci leemveliso ezinomgangatho wengeniso yenzuzo ngaphezulu kwe-10%. Oku kubonisa ukuba nangona ukusebenza ngokubanzi kweshishini lemichiza yaseChina kunenzuzo, izinga lenzuzo alikho phezulu. Ukuqwalasela izinto ezinje ngeendleko zemali, iindleko zolawulo, ukuhla kwexabiso, njl.njl., inqanaba lomda wengeniso kwamanye amashishini linokwehla ngakumbi.

Umda wenzuzo yeemveliso zokwenza ilahleko: Kwimichiza eyenze ilahleko, uninzi lwazo lugxile kuluhlu lwelahleko lwe-10% okanye ngaphantsi. Ukuba ishishini leleprojekthi edibeneyo kwaye linemathiriyeli yalo ehambelanayo, ke iimveliso ezinelahleko encinci zisenokufumana inzuzo.

I-4, Ukuthelekiswa koBume beNzuzo ye-Industrial Chain

Umfanekiso wesi-4 Uthelekiso lwengeniso yengeniso yeemveliso zekhemikhali eziphezulu ezingama-50 zaseTshayina ngo-2024.

Ngokusekwe kumyinge wenqanaba lomyinge wengeniso yekhonkco loshishino apho iimveliso ezingama-50 ziphantsi kwazo, sinokufikelela ezi zigqibo zilandelayo:

Iimveliso ezinengeniso ephezulu: ifilimu ye-PVB, i-octanol, i-trimellitic anhydride, i-Optical grade COC kunye nezinye iimveliso zibonisa iimpawu zenzuzo eyomeleleyo, kunye nenqanaba lenzuzo eliphakathi kwe-30%. Ezi mveliso zihlala zineempawu ezikhethekileyo okanye zibekwe kwindawo esezantsi ngokwentelekiso kwikhonkco loshishino, kunye nokhuphiswano olubuthathaka kunye nemida yengeniso ezinzileyo.

Iimveliso ezenza ilahleko: I-petroleum kwi-ethylene glycol, i-hydrogenated phthalic anhydride, i-ethylene kunye nezinye iimveliso zibonise ilahleko enkulu, kunye nenqanaba lelahleko eliphakathi kwama-35%. I-ethylene, njengemveliso ephambili kushishino lweekhemikhali, ilahleko yayo ngokungangqalanga ibonakalisa ukusebenza kakubi kweshishini lemichiza laseTshayina.

Ukusebenza kwekhonkco loshishino: Ukusebenza ngokubanzi kwe-C2 kunye ne-C4 ye-industrial chain chain ilungile, kunye neyona nxalenye inkulu yeemveliso ezinenzuzo. Oku kubangelwe ikakhulu kukwehla kweendleko zemveliso ezisezantsi ezibangelwa kukudodobala kwemathiriyeli ekrwada yekhonkco leshishini, kwaye iingeniso zigqithiselwa ezantsi ngekhonkco leshishini. Nangona kunjalo, ukusebenza kwesiphelo semathiriyeli ekrwada kumbi kakhulu.

5, Imeko egqithisileyo yokutshintsha konyaka-ngonyaka kumda wenzuzo

I-N-Butane esekwe kwi-anhydride ye-maleic: Umda wayo wengeniso unowona tshintsho lukhulu kunyaka nonyaka, ukusuka kwixabiso eliphantsi lengeniso ngo-2023 ukuya kwilahleko emalunga ne-3% ukusuka ngoJanuwari ukuya kuSeptemba 2024. Oku kubangelwe ikakhulu ngunyaka -unyaka wehla kwixabiso le-anhydride ye-maleic, ngelixa ixabiso lezinto eziluhlaza i-n-butane liye landa, okubangele iindleko ezikhulayo kunye nokunciphisa ixabiso lemveliso.

I-Benzoic anhydride: Umda wayo wenzuzo uye wanda kakhulu malunga ne-900% unyaka nonyaka, okwenza ukuba ibe yimveliso egqithiseleyo ngokubhekiselele kutshintsho lwenzuzo kwiikhemikhali ezininzi kwi-2024. Oku kubangelwa kakhulu ukunyuka kwe-crazy kwimarike yehlabathi ebangelwa ukurhoxiswa kwe-INEOS kwimarike yehlabathi ye-phthalic anhydride.

6. Amathemba ekamva

Ngo-2024, ishishini leekhemikhali lase-China liye lafumana ukwehla konyaka nonyaka kwingeniso epheleleyo kunye nokwehla okukhulu kwingeniso emva kokufumana ukuhla koxinzelelo lweendleko kunye nokwehla kwamaziko exabiso lemveliso. Ngokuchasene nemvelaphi yamaxabiso e-oyile ekrwada azinzile, ishishini lokucoca libone ukuchacha kwengeniso, kodwa izinga lokukhula kwemfuno liye lehla kakhulu. Kwishishini lemichiza yobuninzi, ukuchasana kwe-homogenization kubonakala ngakumbi, kwaye indawo yokubonelela kunye nemfuno iyaqhubeka nokuwohloka.

Kulindeleke ukuba imboni yeekhemikhali zaseTshayina isajongene noxinzelelo oluthile kwisiqingatha sesibini se-2024 kwaye ngaphakathi kwe-2025, kwaye ukulungiswa kwesakhiwo soshishino kuya kuqhubeka kunzulu. Ukuphumelela kwiiteknoloji eziphambili kunye neemveliso ezintsha kulindeleke ukuba ziqhube ukuphuculwa kwemveliso kunye nokukhuthaza uphuhliso oluzinzileyo lwenzuzo ephezulu yeemveliso eziphezulu. Kwixesha elizayo, ishishini lemichiza laseTshayina kufuneka lenze iinzame ezingakumbi kubuchwephesha obutsha, uhlengahlengiso lwesakhiwo, kunye nophuhliso lwentengiso ukumelana nemingeni yangoku neyexesha elizayo.
