Ixabiso lendawo yepolyvinyl chloride (PVC) yehla ngokuqhubekayo
Ixabiso lendawo ye-polyvinyl chloride (PVC) yawela kwi-6,711.43 yuan / itoni ngo-Agasti 4, ukuhla kwe-1.2% ngosuku, ukunyuka kweveki ye-3.28%, kunye nokuhla kwenyanga ye-7.33%.

Ixabiso lendawo ye-caustic soda lenyuka laya kwi-1080.00 yuan / ton ngo-Agasti 4, ukunyuka kwe-0% ngosuku, ukuhla kweveki nge-1.28%, kunye nokwehla kwenyanga nge-12.34%.

IiDatha ezahlukeneyo zosuku Iyunithi yokunyuka nokuwa kweveki Ukunyuka nokuwa kweveki Ukunyuka nokuwa kwenyanga
Ixabiso lendawo: PVC 6711.43 yuan / itoni -1.2% 3.28% -7.33%
ixabiso indawo: caustic soda 1080.00 yuan / ton 0% -1.28% -12.34%

Ishishini le-chlor-alkali lishishini elibalulekileyo leekhemikhali ezisisiseko, kwaye iimveliso zabameli abaphambili ziyi-caustic soda kunye ne-polyvinyl chloride (PVC).

i-caustic soda

Ekupheleni kuka-2020, umthamo wemveliso wehlabathi jikelele we-caustic soda ufikelele kwi-99.959 yezigidi zeetoni, kunye nomthamo wemveliso ye-soda ye-caustic e-China yafikelela kwi-44.7 yezigidi zeetoni, i-accounting ye-44.7% yomthamo wemveliso yehlabathi, ibeka kuqala kwihlabathi kwimveliso. umthamo.

Ukusukela ngo-2020, ukuhanjiswa kwamandla emveliso kwimarike ye-caustic soda yelizwe lam kuye kwacaca ngokuthe ngcembe, ikakhulu kwimimandla emithathu yoMntla we-China, kuMntla-ntshona we-China kunye ne-East China.Le mimandla mithathu ingentla 'umthamo wemveliso ye-caustic soda yenza ngaphezulu kwe-80% yesakhono semveliso yelizwe.Phakathi kwabo, umlinganiselo wommandla omnye eMntla China uqhubekile nokunyuka, ufikelele kwi-37.40%.Umthamo wemveliso ye-caustic soda kwi-Southwest China, i-South China kunye ne-Northeast China iphantsi, kwaye isabelo somthamo opheleleyo wemveliso kwingingqi nganye yi-5% okanye ngaphantsi.

Okwangoku, imigaqo-nkqubo yemizi-mveliso efana nohlaziyo lwelizwe lonikezelo-icala lizinzisile izinga lokukhula komthamo wemveliso ye-caustic soda industry, kwaye kwangaxeshanye, iphethini yokhuphiswano iqhubekile ukwenziwa ngcono, kwaye ukugxininiswa kweshishini kuye kwaqhubeka. Nyusa.

I-PVC

I-PVC, okanye i-polyvinyl chloride, yayikhe yaba yeyona plastiki inkulu yenjongo jikelele emhlabeni kwaye yayisetyenziswa ngokubanzi.Okwangoku, kukho iimarike ezinkulu ezimbini zabathengi bePVC kwilizwe lam: iimveliso ezinzima kunye neemveliso ezithambileyo.Iimveliso eziqinileyo ubukhulu becala ziiprofayili ezahlukeneyo, imibhobho, iipleyiti, amaphepha aqinileyo kunye neemveliso zokubumba, njl.;Iimveliso ezithambileyo ubukhulu becala ziifilimu, iingcingo kunye neentambo, ufele olungelulo, iilaphu zokwaleka, imibhobho eyahlukeneyo, iiglavu, iithoyi, isigqubuthelo somgangatho ngeenjongo ezahlukeneyo, izihlangu zeplastiki, kunye nezinye izinto zokuhombisa ezikhethekileyo kunye nezitywini, njl.

Ngokwembono yemfuno, kwiminyaka yakutshanje, imfuno ye-PVC resin kwilizwe lam iye yanda ngokuthe ngcembe.Ngo-2019, ukusetyenziswa okubonakalayo kwe-PVC resin e-China kwafikelela kwi-20.27 yezigidi zeetoni, ukonyuka konyaka nge-7.23%.Ngezicelo ezahlukeneyo ze-polyvinyl chloride resin, kulindeleke ukuba ukusetyenziswa kwe-polyvinyl chloride resin kwilizwe lam kuya kufikelela kwi-22.109 yezigidi zeetoni ngo-2021, kwaye ithemba lemarike likhulu.

Isishwankathelo soShishino lweChlor-Alkali

Ulwakhiwo olusisiseko lwetyathanga leshishini kukusebenzisa indlela ye-diaphragm okanye indlela ye-ionic inwebu yokucoca amanzi etyuwa ukuze ufumane iklorini imathiriyeli ekrwada, kwaye kwangaxeshanye ivelise i-caustic soda, kunye negesi yeklorini isetyenziswa njengento ekrwada yePVC. imveliso.

Ukususela kumbono womjikelezo wezoqoqosho, imboni ye-chlor-alkali ichaphazeleka kakhulu yimeko ye-macroeconomic.Xa i-macro-economy iphucula, imboni ye-chlor-alkali iqhutywe ngokusetyenziswa kwaye ikhula ngokukhawuleza;xa i-macro-economy iphantsi, imfuno yoshishino lwe-chlor-alkali iyancipha, nangona impembelelo ye-cyclical ine-lag ethile., kodwa umkhwa woshishino lwe-chlor-alkali ngokusisiseko uhambelana noqoqosho olukhulu.

Ngophuhliso olukhawulezayo loqoqosho olukhulu lwelizwe lam kunye nenkxaso yemfuno eyomeleleyo evela kwintengiso yezindlu nomhlaba, imodeli exhasayo ye "PVC + caustic soda" yoshishino lwelizwe lam lwe-chlor-alkali iphuhliswe ngomyinge omkhulu, kunye nomthamo wemveliso kunye nemveliso. ikhule ngokukhawuleza.ilizwe lam liye laba ngumvelisi obaluleke kakhulu kwihlabathi kunye nomthengi weemveliso ze-chlor-alkali.
