Ukuhlaziywa kochungechunge lwemboni ye-PVC kanye nokubukeka kwemakethe
I-Polyvinyl chloride (i-PVC) ingenye yezinhlanu ezinhlanu ezijwayelekile.Yakhiwa nge-polymerization yamahhala yama-vinyl chloride monomers.Ukusetshenziswa kwe-PVC kukleliswe endaweni yesithathu phakathi kwama-resins ayizinjongo ezinhlanu.Njengenye yezinhlobo ezibalulekile zekusasa lemboni yamakhemikhali, i-PVC ihlaziywa okokuqala kuleli phepha.Okwesibili, inkontileka eyinhloko ye-PVC iye yabhekana nokwehla okukhulu kusukela ngoJuni, futhi ingene esigabeni sokuhlanganisa uhla.Uhlangothi lwesidingo lusesesimweni seqiniso elibuthakathaka.Isikhathi esiphezulu ngoSepthemba sesidlulile, futhi ukwanda kwesidingo ngo-Okthoba kudinga ukuqinisekiswa.Uma ukwanda kwesidingo ngo-Okthoba kuletha ukwehla okucacile kwe-inventory, futhi ukuphindaphinda okulindelekile kwentengo ye-calcium carbide ohlangothini lwezindleko kuzoletha ukusekelwa okuphansi, i-PVC kulindeleke ukuthi isekelwe.Kufakwe i-rebound encane.Kodwa-ke, uhlangothi lwamanje lokuhlinzeka nge-PVC lunamandla amaningi okukhiqiza ekota yesine.Uma uhlangothi lwesidingo lungaboni ukuthuthukiswa okuphawulekayo, i-inventory ingase ihlale isezingeni eliphezulu, futhi i-PVC izogcina ukusebenza okubuthakathaka.
01. Uchungechunge lwemboni ye-PVC - ukuphela kwempahla eluhlaza
Okokuqala, isingeniso esifushane se-polyvinyl chloride, i-polyvinyl chloride (i-Polyvinyl Chloride, i-PVC kafushane), iyimpushana emhlophe engenabuthi, engenaphunga enokuqina kwamakhemikhali aphezulu kanye nepulasitiki enhle.Ngokwendlela yokuthola i-vinyl chloride monomer, ingahlukaniswa ngendlela ye-calcium carbide, indlela ye-ethylene kanye ne-monomer (EDC, VCM) indlela ye-monomer (indlela ye-ethylene kanye nendlela ye-monomer engenisiwe ngokuvamile ebizwa ngokuthi indlela ye-ethylene), phakathi okuyinto indlela ethylene iningi emhlabeni., izwe lami ngokuyinhloko lisekelwe endleleni ye-calcium carbide PVC, ingxenye ye-PVC ekhiqizwa indlela ye-calcium carbide ingaphezu kuka-70%.Kungani izwe lethu lihlukile ezindleleni zokukhiqiza ze-PVC ezivamile zamazwe ngamazwe?
Kusukela emzileni wenqubo yokukhiqiza, i-calcium carbide (i-CaC2, i-calcium carbide iyisisetshenziswa esibalulekile samakhemikhali ayisisekelo, ikakhulukazi asetshenziselwa ukukhiqiza igesi ye-acetylene. Ibuye isetshenziswe ekuhlanganiseni kwe-organic, i-oxyacetylene welding, njll.) endleleni ye-calcium carbide ilandisa cishe I-70% yezindleko zokukhiqiza, Enye yezinto zokusetshenziswa eziyinhloko ze-calcium carbide, i-orchid, yenziwe ngamalahle.Izwe linezici zamalahle anothile, uwoyela ongemuhle kanye negesi encane.Ngakho-ke, inqubo yokukhiqiza ye-PVC yasekhaya isekelwe ikakhulukazi ku-calcium carbide.Kungabonakala futhi kumkhuba wentengo ye-calcium carbide kanye nentengo yasekhaya ye-PVC ukuthi njengempahla eluhlaza eyinhloko ye-PVC, ukuhlobana kwentengo phakathi kwakho kokubili kuphezulu kakhulu.
Emazweni omhlaba, umzila kawoyela negesi yemvelo (indlela ye-ethylene) isetshenziswa kakhulu, ngakho-ke izindleko nentengo yemakethe azihambisani.
Nakuba izwe lami linomgomo wokulwa nokulahlwa kwe-PVC, abakhiqizi basekhaya basengasebenzisa indlela ye-ethylene ukukhiqiza i-PVC ngokuthenga uwoyela ongahluziwe, i-ethylene kanye ne-VCM monomers.Izinqubo ezahlukene zokukhiqiza ze-PVC zinezindlela ezihlukene zomthelela ohlangothini lwayo lwezindleko.Ngokuhambisanayo, izinguquko kumanani kawoyela ongahluziwe kanye ne-ethylene ekugcineni kwenqubo ye-ethylene zizothinta ukuzimisela kokukhiqizwa kwabakhiqizi be-PVC basekhaya ngenqubo ye-calcium carbide.
02. Iketanga lemboni ye-PVC - ukusetshenziswa komfula ongezansi
Ngokwesidingo, imikhiqizo ye-PVC engezansi ingahlukaniswa ngezinhlobo ezimbili: imikhiqizo eqinile nemikhiqizo ethambile.Imikhiqizo eqinile ihlanganisa okokufakwa kwamapayipi, iminyango namafasitela anephrofayili, amashidi aqinile namanye amashidi.Phakathi kwazo, amapayipi namaphrofayili ayisidingo esibaluleke kakhulu esezansi nomfula, esibalelwa ngaphezu kwama-50%.Njengendlela ebaluleke kakhulu ezansi nomfula, isidingo samapayipi sikhula ngokushesha.Ama-oda we-Enterprise ohamba phambili kanye nokwakhiwa aphakeme, futhi ukusetshenziswa kwezinto zokusetshenziswa ze-PVC kukhuphuke kakhulu.Imikhiqizo ethambile ihlanganisa izinto zokumboza phansi, amafilimu, izinto zekhebula, isikhumba sokwenziwa, izicathulo kanye nezinto zodwa, njll. Eminyakeni yamuva nje, isidingo sokuthekelisa se-PVC flooring sinyukile, esiphenduke isiqondiso esisha sokukhula kwesidingo se-PVC.Mayelana nesidingo esibulalayo, izindlu ezithengiswayo seziphenduke indawo ebaluleke kakhulu emnothweni kazwelonke othinta i-PVC, efinyelela cishe ku-50%, ilandelwa yingqalasizinda, izimpahla ezihlala isikhathi eside, izimpahla ezilahlwayo kanye nezolimo.
03. I-Market Outlook
Ngokombono wochungechunge lwezimboni, ohlangothini lwempahla eluhlaza, amanani amanje amalahle ashisayo nekhabhoni eluhlaza okwesibhakabhaka asezingeni eliphezulu, futhi ayehla ebusika.Uma ubusika obubandayo buphindela, izintengo zamalahle ashisayo kanye nekhabhoni eluhlaza okwesibhakabhaka zingase zikhuphuke ngezinga eliphezulu, okuzoshayela intengo ye-calcium carbide phezulu.Njengamanje, intengo ye-calcium carbide iyaphambuka enanini lamalahle ashisayo kanye nekhabhoni eluhlaza okwesibhakabhaka, ikakhulukazi ngenxa yokuthi intengo ye-PVC engezansi yomfula i-calcium carbide ibuthakathaka.Njengamanje, abakhiqizi be-calcium carbide baye bakhulisa kancane kancane ukulahlekelwa kwabo ngaphansi kwengcindezi yezindleko.Amandla okuxoxisana abakhiqizi be-calcium carbide alinganiselwe, kodwa esimweni sokwandiswa kokulahlekelwa kwezinkampani, kungenzeka ukuthunyelwa kwefekthri ye-calcium carbide ngenani eliphezulu lokukhuphuka.Lokhu futhi kunikeza ukusekelwa kwezindleko eziphansi zamanani e-PVC.
Ngekota yesine, ukubuyiselwa kokuhlinzekwa kulindeleke ukuthi kube namandla.Ngekota yesine, kuzoba namandla okukhiqiza e-PVC amasha ayizigidi eziyi-1.5, okuqinisekile ukuthi izigidi eziyi-1.2 zawo.amathani angu-400,000 amandla amasha okukhiqiza azokhululwa;ngaphezu kwalokho, Jintai has 300,000 amathani isikhathi sokukhiqiza namanje akuqinisekile, ngokuvamile, ingcindezi PVC supply engxenyeni yesine inkulu uma kuqhathaniswa.
Iqiniso elibuthakathaka ohlangothini lwesidingo kanye ne-inventory ephezulu ye-anti-seasonal yizizathu eziyinhloko zentengo ebuthakathaka ye-PVC.Njengoba sibheke phambili ekubukeni kwemakethe, isizini ephezulu yesidingo segolide lendabuko se-PVC sesidlulile.Yize isidingo ngoSepthemba sesithuthukile, sisephansi kunalokho obekulindelwe.Isidingo sibhekene nesivivinyo ngo-Okthoba.Uma isidingo siba ngcono futhi izindleko eziphansi zisekelwa, i-PVC ingase iphinde ikhuphuke kancane.Kodwa-ke, kuhlanganiswe nokwanda okukhulu kokukhiqizwa engxenyeni yesine kanye nengcindezi enkulu yokuhlinzeka, kulindeleke ukuthi i-PVC izogcina ukusebenza okubuthakathaka.
