Ha re hetla morao ka December eohle, halofo ea pele ea khoeli, likonteraka tse ka sehloohong li bontšitse mokhoa o holimo ka lebaka la ho tlosoa ha leano la seoa le ho lokoloha ha leano la thekiso ea matlo.Karolong ea bobeli ea khoeli, ka phello e ncha ea seoa le tlhokahalo e botsoa qetellong ea selemo, boemo ba phepelo le tlhoko bo ile ba hloleha ho fana ka maikutlo a nepahetseng, 'me butle-butle mmaraka o ile oa kena khokahanyong e makatsang.Ho elella bofelong ba selemo, phello ea matsatsi a phomolo e ile ea hlaha hape, e bonts'a mokhoa o akaretsang oa ho nyoloha.
II, tlhahlobo ea matheba
Ts'ebetso ea tlhahiso ea PVC e na le mefuta e 'meli: mokhoa oa khalsiamo carbide le mokhoa oa ethylene, mokhoa oa ethylene oa boleng ba PVC o hloekileng le o ts'oanang, theko e phahame hanyenyane ho feta mokhoa oa PVC oa calcium carbide.Mefuta e fapaneng ea ho fana ka bokamoso ba PVC naheng ea rona ke SG5 grade 1 e tsamaellanang le maemo a naha.Ha ho na lithibelo tse hlakileng mabapi le hore na sehlahisoa sa ho fana se entsoe ke mokhoa oa calcium carbide kapa mokhoa oa vinyl.
Ho tloha ka la 30 Tšitoe 2022, litheko le ho ata ha PVC li bonts'itsoe ka tlase:
Ka letsatsi leo, kakaretso ea theko ea vinyl PVC naheng ea China e ne e le 6,313 yuan/ton, e nyolohetse ho 165 yuan/ton ha e bapisoa le bofelong ba khoeli e fetileng.
Ka letsatsi lona leo, kakaretso ea theko ea lehae ea calcium carbide PVC ke 6,138 yuan/ton, ha e bapisoa le bofelong ba khoeli e fetileng, e nyolohile ho 198 yuan/ton.
Phapang ea theko pakeng tsa mokhoa oa ethylene le mokhoa oa calcium carbide letsatsing leo e ne e le 175 yuan/ton, ha e bapisoa le qetellong ea khoeli e fetileng, ho fihla ho 33 yuan/ton, phapang ea theko e ntse e le boemong bo tlaase ba histori.
Ho tloha ka la 30 Tšitoe 2022, theko ea nakong e tlang ea PVC ke -66 yuan/ton, 3 yuan/ton ka tlase ho letsatsi le fetileng, e leng boemo bo tlase nalaneng.
III.Tlhahlobo ea phepelo
Ka nako e telele, 'maraka oa Chaena oa PVC e bile mokhoa oa tsoelo-pele o nang le mefuta e' meli ea mekhoa ea theknoloji, mokhoa oa calcium carbide le mokhoa oa ethylene, empa ka lebaka la litšobotsi tsa "mashala a ruileng, oli e futsanehileng le khase e fokolang" naheng ea rona, mokhoa oa calcium carbide PVC e fetohile theknoloji e etellang pele naheng ea rona, empa 'marakeng oa machaba, lihlahisoa tse tloaelehileng tsa PVC li entsoe ka mokhoa oa ethylene,' me ethylene e hlahisoa ke ho phatloha ha matla a kang oli le khase.Kahoo theko ea PVC le litheko tsa oli tsa machaba li bonts'a kamano e batlang e le matla.
Tsela ea ts'ebetso ea vinyl PVC ke e latelang: oli e tala - naphtha - ethylene - dichloroethane (EDC) - vinyl chloride (VCM) - polyvinyl chloride (PVC)
Calcium carbide process e sebelisoa haholo likhoebong tsa China tsa tlhahiso ea chlor-alkali ho hlahisa PVC, 'me tlhahiso ea PVC ka calcium carbide process e etsa karolo ea 80% ea kakaretso ea tlhahiso ea China.
Mokhoa oa tlhahiso ea calcium carbide polyvinyl chloride ke: Coal - calcium carbide - acetylene - vinyl chloride (VCM) - polyvinyl chloride (PVC) mokhoa oa ho fokotsa motlakase ke mokhoa o ka sehloohong oa tlhahiso ea indasteri ea calcium carbide hajoale, mokhoa ona o nka coke (2798). , 29.50, 1.07%) le lime e le lisebelisoa tse tala, ho ea ka karo-karolelano e tsitsitseng ea e tsoakiloeng ka sebōpi se koetsoeng sa calcium carbide, Calcium carbide e hlahisoa ke mocheso oa motlakase ho likhato tse 2000-2200.Kaha mokhoa ona o hloka ho sebelisa matla a mangata a motlakase, litšenyehelo tsa motlakase li ikarabella bakeng sa karolo e phahameng ea litšenyehelo tsohle bakeng sa likhoebo tsa tlhahiso ea polyvinyl chloride tse sebelisang mokhoa oa calcium carbide.
Ho akaretsa, theko ea nakong e tlang ea PVC e angoa ke mashala a chesang (0, -921.00, -100.00%) (theko ea motlakase), theko ea coke le calcium carbide ka nako e le 'ngoe, e bonts'a kamano e phahameng.
Ka la 03 Pherekhong 2023, theko ea mashala a mashala a machaena ke 921 yuan/ton, ha e bapisoa le letsatsi le fetileng, ha ho phetoho;Theko ea ho fana ka coke ke 2,610 yuan/ton, ha e bapisoa le letsatsi le fetileng, e theohile ka 95 yuan/ton.
Ho tloha ka la 30 Tšitoe 2022, kakaretso ea theko ea khalsiamo lifekthering tse kholo tsa calcium carbide ka Leboea-bophirima ho China ke 3,910 yuan/ton, e sa fetoheng ha e bapisoa le letsatsi le fetileng.Theko ea sebaka sa calcium carbide naheng ke 4,101 yuan/ton, ha e bapisoa le letsatsi le fetileng, ha ho phetoho.
Ha likhoebo tsa chlor-alkali li hlahisa chlorine ea metsi, li boetse li fumana caustic soda, sehlahisoa se amanang.Lilemong tsa morao tjena, theko ea caustic soda le chlorine ea metsi e theha phello ea seesaw, ke hore, ha theko ea caustic soda e phahame, theko ea chlorine ea metsi e batla e le tlaase, 'me ka tsela e fapaneng, e etsang phaello ea chlor-alkali. likhoebo li boloka maemong a loketseng.Mokelikeli oa chlorine o thata ho boloka le ho tsamaisoa libakeng tse telele, kahoo bahlahisi ba atisa ho kopanya PVC le ho sebelisa lihlahisoa tse ngata tsa chlorine tsa metsi.
Karolo e tlase ea caustic soda haholo e kenyelletsa alumina, ho etsa pampiri, ho hatisa le ho daea le liindasteri tsa lik'hemik'hale.Ho futhumala ha noka e tlase ea caustic soda ho tla tsamaisa keketseho ea tlhahiso ea soda le ho feta ea likhoebo tsa chlor-alkali, 'me sehlahisoa se amanang le chlorine ea metsi e tla etsoa PVC, ka hona ho eketsa phepelo ea' maraka ea PVC, e tla hatella theko ea 'maraka. PVC ho isa tekanyong e itseng.Ka kakaretso, litheko tsa PVC li lula li le holimo ha litheko tsa soda le ho feta li le tlase.
Ho tloha ka la 30 Tšitoe 2022, theko ea sebaka sa ionic membrane caustic soda ke 1,344 yuan/ton, ha e bapisoa le letsatsi le fetileng, ha ho na phetoho, 'me theko ea hona joale e boemong bo phahameng ba histori.
Hona joale, tlhokahalo e kholo ea soda ea caustic Chaena e tsoa ho sehokelo sa tlhahiso ea alumina, kahoo theko ea caustic soda le theko ea alumina e bontša kamano e phahameng.
Aluminium ea lapeng ea electrolytic e sebelisoa haholo indastering ea thekiso ea matlo le meaho, ea likoloi le ea motlakase.Ho tsosolosoa ha liindasteri tsena tse tlaase ho tla eketsa tlhokahalo ea lihlahisoa tsa aluminium, tse tla fetisetsoa ho ea holimo, ho phahamisa theko ea caustic soda le ho ama ka tsela e sa tobang mokhoa oa theko ea bokamoso ba PVC.
Ho tloha ka la 30 Tšitoe 2022, theko ea matheba ea alumina ea lapeng ke 2,965 yuan/ton, ha ho phetoho ha e bapisoa le letsatsi le fetileng, 'me theko ea hajoale e maemong a tloaelehileng a nalane.
