Intengo yendawo ye-polyvinyl chloride (PVC) yehla ngokuqhubekayo
Intengo yendawo ye-polyvinyl chloride (PVC) yehle yaya ku-6,711.43 yuan / ton ngo-Agasti 4, yehle ngo-1.2% ngosuku, inyuka masonto onke ngo-3.28%, kanye nokwehla kwanyanga zonke ngo-7.33%.

Intengo yendawo ye-caustic soda ikhuphuke yafinyelela ku-1080.00 yuan / ton ngo-Agasti 4, inyuke ngo-0% ngosuku, yehla masonto onke ngo-1.28%, kanye nokwehla kwanyanga zonke ngo-12.34%.

Idatha Ehlukahlukene yosuku Iyunithi yokuvuka nokuwa kosuku Ukuvuka nokuwa kwamasonto onke Ukuvuka nokuwa kwanyanga zonke
Intengo yendawo: PVC 6711.43 yuan / ton -1.2% 3.28% -7.33%
Intengo yendawo: i-caustic soda 1080.00 yuan / ithani 0% -1.28% -12.34%

Imboni ye-chlor-alkali iyimboni yamakhemikhali eyisisekelo ebalulekile, futhi imikhiqizo emele kakhulu i-caustic soda ne-polyvinyl chloride (PVC).

i-caustic soda

Ekupheleni kuka-2020, umthamo wokukhiqiza we-caustic soda emhlabeni wonke ufinyelele amathani ayizigidi ezingu-99.959, futhi umthamo wokukhiqiza we-caustic soda e-China ufinyelele amathani ayizigidi ezingu-44.7, okubalelwa ku-44.7% wengqikithi yokukhiqiza emhlabeni, ibekwe kuqala emhlabeni ekukhiqizeni. umthamo.

Kusukela ngo-2020, ukusatshalaliswa kwamandla okukhiqiza kwemakethe ye-caustic soda yezwe lami sekuye kwacaca kancane kancane, ikakhulukazi ezifundeni ezintathu zaseNyakatho neChina, eNyakatho-ntshonalanga yeChina naseMpumalanga yeChina.Izifunda ezintathu ezingenhla amandla okukhiqiza i-caustic soda zenza ngaphezu kwama-80% omthamo wokukhiqiza wezwe usuwonke.Phakathi kwazo, ingxenye yesifunda esisodwa eNyakatho neChina iqhubekile nokukhula, yafinyelela ku-37.40%.Amandla okukhiqiza i-caustic soda eNingizimu-ntshonalanga yeChina, eNingizimu yeChina naseNyakatho-mpumalanga yeChina aphansi uma kuqhathaniswa, futhi isabelo samandla okukhiqiza aphelele esifundeni ngasinye singama-5% noma ngaphansi.

Njengamanje, izinqubomgomo zezimboni ezifana noguquko oluseceleni lokuhlinzekwa kwempahla kuzwelonke zizinzile izinga lokukhula kwamandla okukhiqiza embonini ye-caustic soda, futhi ngesikhathi esifanayo, iphethini yokuncintisana iqhubekile nokuthuthukiswa, futhi ukugxilwa kwemboni kuqhubekile ukwanda.

I-PVC

I-PVC, noma i-polyvinyl chloride, yake yaba ipulasitiki enkulu kunazo zonke emhlabeni futhi yayisetshenziswa kabanzi.Njengamanje, kunezimakethe ezimbili ezinkulu zabathengi be-PVC ezweni lami: imikhiqizo eqinile nemikhiqizo ethambile.Imikhiqizo eqinile ikakhulukazi amaphrofayili ahlukahlukene, amapayipi, amapuleti, amashidi aqinile kanye nemikhiqizo yokubumba evuthelayo, njll.;imikhiqizo ethambile ikakhulukazi amafilimu, izintambo kanye nezintambo, isikhumba sokwenziwa, izindwangu zendwangu, amapayipi ahlukahlukene, amagilavu, amathoyizi, okokumboza phansi ngezinjongo ezihlukahlukene izinto zokwakha, izicathulo zepulasitiki, nezinye izinto ezikhethekile zokumboza nama-sealant, njll.

Ngokombono wesidingo, eminyakeni yamuva nje, isidingo se-PVC resin ezweni lami sikhule kancane kancane.Ngo-2019, ukusetshenziswa okusobala kwe-PVC resin e-China kwafinyelela amathani ayizigidi ezingama-20.27, okuwukunyuka konyaka ngo-7.23%.Ngokusetshenziswa okuhlukahlukene kwe-polyvinyl chloride resin, kulindelekile ukuthi ukusetshenziswa kwe-polyvinyl chloride resin ezweni lami kuzofinyelela kumathani ayizigidi ezingama-22.109 ngo-2021, futhi ithemba lemakethe likhulu.

Uhlolojikelele lwe-Chlor-Alkali Industry

Isakhiwo esiyisisekelo sochungechunge lwezimboni ukusebenzisa indlela ye-diaphragm noma indlela ye-ionic membrane ukuze kusetshenziswe amanzi anosawoti e-electrolyze ukuthola izinto zokusetshenziswa ze-chlorine, futhi ngesikhathi esifanayo ukukhiqiza ngokuhlanganyela i-caustic soda, kanye negesi ye-chlorine isetshenziswa njengento eluhlaza ye-PVC. ukukhiqiza.

Ngokombono womjikelezo wezomnotho, imboni ye-chlor-alkali ithintwa kakhulu isimo somnotho omkhulu.Lapho umnotho omkhulu uthuthuka, imboni ye-chlor-alkali iqhutshwa ukusetshenziswa futhi ikhula ngokushesha;lapho umnotho omkhulu wehla, isidingo semboni ye-chlor-alkali siyehla, nakuba umthelela we-cyclical une-lag ethile., kodwa inkambiso yemboni ye-chlor-alkali ngokuyisisekelo ihambisana nomnotho omkhulu.

Ngokuthuthuka okusheshayo komnotho omkhulu wezwe lami kanye nokusekelwa okuqinile kwesidingo esivela emakethe yezindlu, imodeli esekelayo ye-“PVC + caustic soda” yemboni yezwe lami ye-chlor-alkali ithuthuke ngezinga elikhulu, futhi amandla okukhiqiza kanye nokuphumayo kuye kwathuthuka. ikhule ngokushesha.izwe lami selingumkhiqizi nomthengi obaluleke kakhulu emhlabeni wemikhiqizo ye-chlor-alkali.
