Njye, gusubiramo isoko
PVC (6402, 10.00, 0.16%) amasezerano yingenzi mu Kuboza 30 yarangiye kuri 6263 yuan / toni, ukwezi kuzamuka 312 / toni (5.24%).
Dushubije amaso inyuma mu Kuboza kwose, mu gice cya mbere cy'ukwezi, amasezerano y'ingenzi yerekanaga ko yazamutse bitewe no kuvugurura politiki y'ibyorezo no kurekura politiki y’imitungo itimukanwa.Mu gice cya kabiri cy'ukwezi, hamwe n’icyorezo cy’icyorezo ndetse n’ubushake buke mu mpera z’umwaka, urwego rutangwa n’ibisabwa ntirwashoboye gutanga ibitekerezo byiza, maze isoko ryinjira buhoro buhoro.Umwaka urangiye, ingaruka zikiruhuko zongeye kugaragara, zerekana muri rusange kuzamuka.
II, gusesengura ahantu
Ibikorwa bya PVC bifite ubwoko bubiri: uburyo bwa calcium karbide nuburyo bwa Ethylene, uburyo bwa Ethylene bwa PVC bufite ireme kandi bumwe, igiciro kiri hejuru gato ya calcium karbide ya PVC.Gutanga ibintu bitandukanye byigihe kizaza cya PVC mugihugu cyacu ni SG5 icyiciro cya 1 gihuye nurwego rwigihugu.Nta mbogamizi isobanutse yerekana niba ibicuruzwa bitangwa bikozwe na calcium karbide cyangwa inzira ya vinyl.
Guhera ku ya 30 Ukuboza 2022, igiciro kiboneka no gukwirakwiza PVC birerekanwa hepfo:
Kuri uwo munsi, impuzandengo y’ibiciro bya vinyl PVC mu Bushinwa yari 6.313 Yuan / toni, yiyongereyeho 165 yu / toni ugereranije n’ukwezi gushize.
Kuri uwo munsi, impuzandengo yikigereranyo cya calcium karbide yo mu gihugu PVC ni 6.138 yuan / toni, ugereranije nu mpera zukwezi gushize, yazamutseho 198 yuan / toni.
Itandukaniro ryibiciro hagati yuburyo bwa Ethylene nuburyo bwa kariside ya calcium kuri uwo munsi yari 175 yuan / toni, ugereranije nu mpera zukwezi gushize, yazamutseho 33 yu / toni, itandukaniro ryibiciro riracyari kurwego rwo hasi rwamateka
Kugeza ku ya 30 Ukuboza 2022, igiciro cya PVC kizaza gikwirakwizwa ni -66 yuan / toni, 3 yuan / toni munsi yumunsi wabanjirije uwo, uri ku rwego rwo hasi mu mateka.
III.Isesengura
Kuva kera, isoko rya PVC ryubushinwa ryabaye inzira yiterambere ribana nubwoko bubiri bwikoranabuhanga, uburyo bwa calcium karbide nuburyo bwa Ethylene, ariko kubera ibiranga "amakara akungahaye, peteroli ikennye na gaze nkeya" mugihugu cyacu, calcium karbide uburyo PVC yabaye tekinoroji yambere mugihugu cyacu, ariko kumasoko mpuzamahanga, ibicuruzwa byingenzi bya PVC bikozwe nuburyo bwa Ethylene, naho Ethylene ikorwa no kumena ingufu nka peteroli na gaze.Igiciro rero cya PVC nibiciro mpuzamahanga bya peteroli byerekana isano ikomeye.
Inzira yuburyo bwa vinyl PVC nuburyo bukurikira: amavuta ya peteroli - naphtha - Ethylene - dichloroethane (EDC) - vinyl chloride (VCM) - polyvinyl chloride (PVC)
Kalisiyumu ya karisiyumu ikoreshwa cyane mu nganda zikora chlor-alkali mu Bushinwa kugira ngo zibyare PVC, naho umusaruro wa PVC ukoresheje kariside ya kariside ugera kuri 80% by’umusaruro wose mu Bushinwa.
Uburyo bwo gukora calcium karbide polyvinyl chloride ni: Amakara - calcium karbide - acetylene - vinyl chloride (VCM) - uburyo bwo kugabanya amashanyarazi polyvinyl chloride (PVC) nuburyo bwibanze bwo gukora inganda za kariside ya calcium muri iki gihe, ubu buryo bufata kokiya (2798) .Nkuko ubu buryo bukeneye gukoresha ingufu nyinshi zamashanyarazi, ikiguzi cyamashanyarazi kigizwe nigice kinini cyikiguzi cyose cyinganda zikora polyvinyl chloride ikoresheje uburyo bwa calcium karbide.
Muri make, igiciro cyigihe kizaza cya PVC kirebwa namakara yumuriro (0, -921.00, -100.00%) (igiciro cyamashanyarazi), kokiya na calcium karbide icyarimwe, byerekana isano iri hejuru.
Kugeza ku ya 03 Mutarama 2023, igiciro cy’amashanyarazi y’amakara y’Ubushinwa ni 921 yuan / toni, ugereranije n’umunsi wabanjirije, nta gihinduka;Igiciro cyo gutanga kokiya ni 2,610 yuan / toni, ugereranije numunsi wabanjirije iki, munsi ya 95 yuan / toni.
Kugeza ku ya 30 Ukuboza 2022, impuzandengo y'ibiciro bya kariside ya calcium mu nganda rusange za calcium karbide mu majyaruguru y'uburengerazuba bw'Ubushinwa ni 3.910 Yuan / toni, nta gihindutse ugereranije n'umunsi wabanjirije uwo.Igiciro cyibibanza bya calcium karbide mugihugu ni 4,101 yuan / toni, ugereranije numunsi wabanjirije, nta gihinduka.
Iyo inganda za chlor-alkali zitanga chlorine y'amazi, zibona na soda ya caustic, ibicuruzwa bifitanye isano.Mu myaka yashize, igiciro cya soda ya caustic na chlorine yamazi bigira ingaruka zo kureba, ni ukuvuga, mugihe igiciro cya soda ya caustic kiri hejuru, igiciro cya chlorine yamazi iba mike ugereranije, naho ubundi, bigatuma inyungu ya chlor-alkali ibigo bikomeza ku rwego rushimishije.Chlorine y'amazi iragoye kubika no gutwarwa ahantu harehare, bityo abayikora bakunda guhuza PVC no gukoresha ububiko bwa chlorine burenze urugero.
Hasi ya soda ya caustic ikubiyemo ahanini alumina, gukora impapuro, gucapa no gusiga amarangi n'inganda zikora imiti.Ubushyuhe bwo hepfo ya soda ya caustic bizatera kwiyongera k'umusaruro wa soda wa caustic w’inganda za chlor-alkali, kandi ibicuruzwa biva mu bwoko bwa chlorine bijyana na byo bizakorerwa muri PVC, bityo byongere byiyongera ku isoko rya PVC, bizamura igiciro cy’isoko rya PVC kurwego runaka.Muri rusange, ibiciro bya PVC bikunda kuguma hejuru mugihe ibiciro bya soda ya caustic biri hasi.
Guhera ku ya 30 Ukuboza 2022, igiciro cya siyoni ya ionic membrane caustic soda ni 1,344 yuan / toni, ugereranije n’umunsi wabanjirije uwo, nta gihinduka, kandi igiciro kiriho kiri ku rwego rwo hejuru mu mateka.
Kugeza ubu, icyifuzo cya soda caustic mu Bushinwa gituruka ku musaruro wa alumina, bityo igiciro cya soda ya caustic nigiciro cya alumina cyerekana isano iri hejuru.
Aluminium yo mu gihugu ikoreshwa cyane mu mutungo utimukanwa, mu nganda z’amashanyarazi n’amashanyarazi.Isubiranamo ry’inganda zimanuka zizamura ibicuruzwa bya aluminiyumu, bizoherezwa hejuru, bizamura igiciro cya soda ya caustic kandi bigira ingaruka ku buryo butaziguye ibiciro by’igihe kizaza cya PVC.
Kugeza ku ya 30 Ukuboza 2022, igiciro cya alumina yo mu gihugu ni 2,965 yuan / toni, nta gihindutse ugereranije n’umunsi wabanjirije iki, kandi igiciro kiriho kiri ku kigereranyo cy’amateka.
