I, dib u eegista suuqa
PVC(6402, 10.00, 0.16%) qandaraaskii ugu weynaa ee Diisambar 30 waxa lagu xidhay 6263 yuan/ton, bishiiba 312 yuan/ton (5.24%).
Dib-u-eegistii Diseembar oo dhan, qeybtii hore ee bisha, qandaraasyada ugu muhiimsan waxay muujiyeen isbeddel sare oo ay ugu mahadcelinayaan xakamaynta siyaasadda faafa iyo dabacsanaanta siyaasadda hantida maguurtada ah.Qeybtii labaad ee bisha, dib-u-soo-noqoshada cudurka faafa iyo baahida gaabis ah ee dhamaadka sanadka, heerka saadka iyo baahida ayaa ku guuldareystay inay bixiso jawaab celin wanaagsan, suuquna wuxuu si tartiib tartiib ah u galay xoojinta naxdinta leh.Ku dhawaad dhamaadka sanadka, saamaynta fasaxa ayaa sii kordheysa, taasoo muujinaysa kor u kaca guud ahaan.
II, falanqaynta dhibcaha
Habka wax-soo-saarka PVC wuxuu leeyahay laba nooc: Habka carbide calcium iyo habka ethylene, habka ethylene ee tayada PVC ee saafiga ah iyo lebbiska, qiimuhu wax yar ayuu ka sarreeyaa habka PVC carbide calcium.Soo gudbinta kala duwan ee mustaqbalka PVC ee dalkeena waa SG5 fasalka 1 oo waafaqsan heerka qaranka.Ma jiraan wax xaddidaad ah oo cad oo ku saabsan in badeecada dhalmada lagu sameeyay habka kaarbiide calcium ama habka vinyl.
Laga bilaabo Diseembar 30, 2022, qiimaha booska iyo fiditaanka PVC ayaa lagu muujiyay hoos:
Maalintaas, celceliska qiimaha booska vinyl PVC ee Shiinaha wuxuu ahaa 6,313 yuan/ton, ilaa 165 yuan/ton marka la barbar dhigo dhamaadkii bishii hore.
Isla maalintaas, celceliska qiimaha booska guriga ee kaalshiyam carbide PVC waa 6,138 yuan/ton, marka la barbar dhigo dhamaadka bishii hore, kor u kacay 198 yuan/ton.
Farqiga qiimaha u dhexeeya habka ethylene iyo habka calcium carbide maalintaas wuxuu ahaa 175 yuan / ton, marka la barbardhigo dhamaadkii bishii hore, ilaa 33 yuan / ton, farqiga qiimaha ayaa weli ku jira heer hoose oo taariikhi ah.
Laga bilaabo Diseembar 30, 2022, qiimaha booska mustaqbalka ee PVC waa -66 yuan/ton, 3 yuan/ton ayaa ka hooseeya maalintii hore, taas oo ah heer hoose taariikhda.
III.Falanqaynta sahayda
Muddo dheer, suuqa PVC ee Shiinaha wuxuu ahaa qaab horumarineed oo la socda laba nooc oo ah khadadka tignoolajiyada, habka calcium carbide iyo habka ethylene, laakiin sababtoo ah sifooyinka "dhuxusha hodanka ah, saliidda saboolka ah iyo gaasta yar" ee dalkeena. Habka carbide calcium PVC waxay noqotay tignoolajiyada hormuudka u ah dalkeena, laakiin suuqa caalamiga ah, alaabada PVC ee caadiga ah waxaa lagu sameeyaa habka ethylene, iyo ethylene waxaa lagu soo saaraa dildilaaca tamarta sida saliidda iyo gaasta.Markaa qiimaha PVC iyo qiimaha saliidda caalamiga ah waxay muujinayaan isku-xirnaan xoog leh.
Habka geeddi-socodka ee vinyl PVC waa sida soo socota: saliid cayriin - naphtha - ethylene - dichloroethane (EDC) - vinyl chloride (VCM) - polyvinyl chloride (PVC)
Habka carbide calcium waxaa si ballaaran loo isticmaalaa in shirkadaha wax soo saarka chlor-alkali Chinese si ay u soo saaraan PVC, iyo wax soo saarka ee PVC by habka carbide calcium xisaabiyaa qiyaastii 80% ee wadarta wax soo saarka ee Shiinaha.
Habka wax soo saarka ee kalsiyum carbide polyvinyl chloride waa: Dhuxul - kalsiyum carbide - acetylene - vinyl chloride (VCM) - polyvinyl chloride (PVC) habka dhimista korontada waa habka caadiga ah ee wax soo saarka ee kalsiyum carbide hadda, habkani wuxuu qaataa coke (2798). , 29.50, 1.07%) iyo lime sida alaabta ceeriin, marka loo eego saamiga go'an ee isku qasan foornada carbide calcium xiran, Kaalshiyam carbide waxaa soo saaray by kululaynta koronto ilaa 2000-2200 degrees.Maadaama habkani u baahan yahay in la isticmaalo qadar badan oo tamar koronto ah, kharashka korantadu wuxuu xisaabiyaa qayb sare oo ka mid ah kharashka guud ee shirkadaha wax soo saarka polyvinyl chloride iyadoo la adeegsanayo habka kaalshiyamka carbide.
Marka la soo koobo, qiimaha mustaqbalka ee PVC waxaa saameeya dhuxusha kulaylka (0, -921.00, -100.00%) (qiimaha korantada), qiimaha kookaha iyo kaarbiidka calcium isku mar, oo muujinaya xiriir sare.
Ilaa Janaayo 03, 2023, qiimaha mustaqbalka dhuxusha tamarta Shiinaha waa 921 yuan/ton, marka la barbar dhigo maalintii hore, wax isbeddel ah ma jiro;Qiimaha keenista Coke waa 2,610 yuan/ton, marka la barbar dhigo maalintii hore, hoos 95 yuan/ton.
Laga bilaabo Diseembar 30, 2022, celceliska qiimaha kaalinta kaalshiyamka carbide ee warshadaha caadiga ah ee kaalshiyam carbide ee Waqooyi-galbeed Shiinaha waa 3,910 yuan/ton, kaas oo aan wax isbeddel ah lahayn marka la barbar dhigo maalintii hore.Sicirka kaalinta calcium carbide ee dalka waa 4,101 yuan/ton, marka la barbar dhigo maalintii hore, wax isbedel ah ma jiraan.
Marka shirkadaha chlor-alkali ay soo saaraan koloriin dareere ah, waxay sidoo kale helaan soodhaha caustic, oo ah badeecad la xiriirta.Sanadihii la soo dhaafay, qiimaha soodhaha caustic iyo koloriin dareeraha ah waxay sameeyaan saameyn seesaw ah, taas oo ah, marka qiimaha soodhaha caustic uu sarreeyo, qiimaha koloriinta dareeraha ah waa mid aad u hooseeya, taas beddelkeeda, taas oo ka dhigaysa faa'iidada chlor-alkali. ganacsiyadu waxay ku hayaan heer macquul ah.Koloriin dareere ah way adagtahay in la kaydiyo lana raro masaafo dheer, sidaa awgeed soosaarayaashu waxay u janjeeraan inay farsameeyaan PVC oo ay isticmaalaan kaydka koloriin ee dareeraha ah.
Dusha hoose ee soodhaha caustic inta badan waxaa ka mid ah alumina, samaynta waraaqaha, daabacaadda iyo rinjiyeynta iyo warshadaha kiimikada.Kuleyliyaha soodhada caustic soodhaha ayaa kor u qaadi doona kororka soodhaha soodhaha ee shirkadaha chlor-alkali, iyo wax soo saarka koloriin dareeraha ah waxaa laga dhigi doonaa PVC, sidaas darteed si xamaasad leh u kordhinta sahayda suuqa ee PVC, taas oo cadaadis saari doonta qiimaha suuqa PVC ilaa xad.Guud ahaan, qiimaha PVC waxay u muuqdaan inay sii ahaanayaan kuwo sarreeya marka qiimaha soodhaha caustic uu hooseeyo.
Laga bilaabo Diseembar 30, 2022, qiimaha barta ionic membrane caustic soda waa 1,344 yuan/ton, marka la barbar dhigo maalintii hore, ma jiro wax isbeddel ah, qiimaha hadda wuxuu joogaa meel sare oo taariikhi ah.
Waqtigan xaadirka ah, baahida ugu weyn ee soodhaha caustic ee Shiinaha waxay ka timaadaa isku xirka wax soo saarka alumina, sidaas darteed qiimaha soodhaha caustic iyo qiimaha alumina ayaa muujinaya xiriir sare.
Aluminium elektrolytic ah oo gudaha ah ayaa si weyn loogu isticmaalaa guryaha, baabuurta iyo warshadaha korontada.Dib u soo kabashada warshadahan hoose waxay kordhin doontaa baahida alaabooyinka aluminium, taas oo loo gudbin doono korka sare, riixaya qiimaha soodhaha caustic iyo si aan toos ahayn u saameeya isbeddelka qiimaha ee mustaqbalka PVC.
Laga bilaabo Diseembar 30, 2022, qiimaha barta aluminiumka gudaha waa 2,965 yuan/ton, wax isbeddel ah ma jiro marka la barbar dhigo maalintii hore, qiimaha hadda wuxuu joogaa celceliska booska taariikhiga ah.
