Ongororo yePVC indasitiri chain uye musika maonero
Polyvinyl chloride (PVC) ndechimwe chezvishanu zvakajairika-chinangwa resin.Iyo inoumbwa nemahara radical polymerization yevinyl chloride monomers.Kushandiswa kwePVC kunoisa chechitatu pakati pezvishanu zvakajairika-chinangwa resin.Seimwe yeakakosha remangwana akasiyana eindasitiri yemakemikari, PVC inotanga kuongororwa mubepa rino.Chechipiri, kondirakiti huru yePVC yakaona kudzikira kwakanyanya kubva munaJune, uye yakapinda munhanho yekubatanidza-yakasungwa.Rutivi rwekudiwa ruchiri mumamiriro echokwadi asina simba.Mwaka wepamusoro munaGunyana wapfuura, uye kuwedzera kwekudiwa muna Gumiguru kunoda kusimbiswa.Kana kuwedzera kwekudiwa muna Gumiguru kunounza kuderera kwakajeka kwezvinyorwa, uye inotarisirwa kudzokororwa mumutengo we calcium carbide padivi remutengo uchaunza pasi rutsigiro, PVC inotarisirwa kutsigirwa.Yakapinzwa mudiki rebound.Nekudaro, iyo yazvino PVC yekugovera divi ine yakawanda nyowani yekugadzira kugona mukota yechina.Kana rutivi rwekudiwa rusingaoni kuvandudzwa kwakakosha, iyo inventory inogona kuramba iri padanho repamusoro, uye PVC inochengetedza isina simba kushanda.

01. PVC industry chain - raw material end

Chokutanga pane zvose, sumo pfupi yepolyvinyl chloride, polyvinyl chloride (Polyvinyl Chloride, PVC kwenguva pfupi), ipfumbu isina chepfu, isina kunhuwa ine kugadzikana kwemakemikari uye yakanaka plastiki.Zvinoenderana nenzira yekuwana vinyl chloride monomer, inogona kukamurwa kuita calcium carbide nzira, ethylene nzira uye kunze kwenyika (EDC, VCM) monomer nzira (iyo ethylene nzira uye kunze kwenyika monomer nzira inowanzonzi iyo ethylene nzira), pakati iyo iyo ethylene nzira ndiyo yakawanda munyika., nyika yangu inonyanya kubva pa calcium carbide nzira PVC, chikamu chePVC chinogadzirwa ne calcium carbide nzira inodarika 70%.Nei nyika yedu yakasiyana neyepasi rose nzira dzekugadzira PVC?

Kubva munzira yekugadzira, calcium carbide (CaC2, calcium carbide yakakosha kemikari yakabikwa, inonyanya kushandiswa kugadzira acetylene gasi. Inoshandiswawo muorganic synthesis, oxyacetylene welding, zvichingodaro) mu calcium carbide nzira inoverengera. 70% yemutengo wekugadzira, Imwe yemhando huru ye calcium carbide, orchid, inogadzirwa nemarasha.Nyika ine hunhu hwemarasha akapfuma, mafuta asina kunaka uye gasi shoma.Naizvozvo, iyo yekumba yePVC yekugadzira maitiro inonyanya kuenderana necalcium carbide.Izvo zvinogona zvakare kuoneka kubva kumaitiro e calcium carbide mutengo uye wepamba PVC mutengo kuti seyakanyanya mbishi zvinhu zvePVC, mutengo wekudyidzana pakati pezviviri izvi wakakwira zvakanyanya.

Munyika yose, nzira yemafuta uye yegasi (ethylene nzira) inonyanya kushandiswa, saka mutengo uye mutengo wemusika hazvienderani.

Kunyangwe nyika yangu iine anti-dumping policy paPVC, vagadziri vemumba vanogona vachiri kushandisa ethylene nzira kugadzira PVC nekutenga mafuta asina kuchena, ethylene uye VCM monomers.Yakasiyana PVC maitiro ekugadzira ane akasiyana maitiro nzira padivi remutengo wayo.Saizvozvo, shanduko mumitengo yemafuta asina kuchena uye ethylene pakupera kwezvinhu ethylene process inokanganisa kugadzirwa kwevagadziri vePVC vepamba necalcium carbide process.

02. PVC industry chain - pasi pemvura inoshandiswa

Panyaya yekuda, PVC yakadzika zvigadzirwa zvinogona kukamurwa kuita mhando mbiri: yakaoma zvigadzirwa uye zvinyoro zvigadzirwa.Zvigadzirwa zvakaomarara zvinosanganisira pombi fittings, profiled magonhi nemahwindo, akaomarara mashiti uye mamwe mapepa.Pakati pazvo, mapaipi nemaprofiles ndiwo akanyanya kukosha pasi pemvura kudiwa, achiverengera anopfuura makumi mashanu%.Sezvo inonyanya kukosha pasi pemvura, kudiwa kwepombi kuri kukura nokukurumidza.Inotungamira real estate uye kuvaka Enterprise maodha akakwira, uye kushandiswa kwePVC mbishi zvinhu kwakawedzera zvakanyanya.Zvigadzirwa zvakapfava zvinosanganisira zvinhu zvekufukidzira pasi, mafirimu, zvinhu zvetambo, dehwe rekugadzira, shangu uye zvinhu zvega, nezvimwewo. Mumakore achangopfuura, kudiwa kwePVC kwepasi kwakawedzera, iyo yava nzira itsva yePVC inoda kukura.Panyaya yekuda kudiwa, zvivakwa zvave nzvimbo inonyanya kukosha yehupfumi hwenyika inobata PVC, inoverengera ingangoita 50%, ichiteverwa nezvivakwa, zvinhu zvinogara, zvinhu zvinoraswa uye zvekurima.

03. Market Outlook

Kubva pakuona kweketani yeindasitiri, padivi rezvakagadzirwa, mitengo yazvino yemarasha ekupisa uye kabhoni yebhuruu iri pamazinga akakwirira, uye inodonha munguva yechando.Kana kutonhora kwechando kuchidzoka, mitengo yemarasha anopisa uye bhuruu kabhoni inogona kukwira pahupamhi hwepamusoro, iyo inotyaira mutengo we calcium carbide kumusoro.Parizvino, mutengo we calcium carbide uri kutsauka kubva pamutengo wemarasha ekupisa uye bhuruu kabhoni, kunyanya nekuti iyo yakadzika PVC mutengo we calcium carbide hauna simba.Parizvino, vagadziri ve calcium carbide vakawedzera zvishoma nezvishoma kurasikirwa kwavo pasi pekumanikidzwa kwemutengo.Simba rekutengeserana kwevagadziri ve calcium carbide ishoma, asi munyaya yekuwedzera kwekurasikirwa kwekambani, mukana wekutengesa kwefekitari ye calcium carbide pamutengo wepamusoro unowedzera.Izvi zvinopawo mari yepasi rutsigiro rwemitengo yePVC.

Muchikamu chechina, kudzorerwa kwekupa kunotarisirwa kuva kwakasimba.Muchikamu chechina, pachange paine miriyoni 1.5 itsva yekugadzira PVC, iyo miriyoni 1.2 ine chokwadi.400,000 matani ehunyanzvi hwekugadzira huchaburitswa;uyezve, Jintai ane 300,000 matani kugadzirwa nguva achiri asina chokwadi, kazhinji, kumanikidzwa pamusoro PVC kupa mukota yechina yakakura.

Chokwadi chisina kusimba padivi rekuda uye iyo anti-mwaka yakakwira inventory ndizvo zvikonzero zvikuru zvemutengo usina simba wePVC.Tichitarisira kutaridzika kwemusika, mwaka wepamusoro wePVC yechinyakare kudiwa kwegoridhe yapfuura.Kunyangwe kudiwa kwaGunyana kwave nani, kuchiri kuderera pane zvanga zvichitarisirwa.Demand yakatarisana nebvunzo muna Gumiguru.Kana kudiwa kuchivandudzika uye mutengo wepasi uchitsigirwa, PVC inogona kudzoka zvishoma.Nekudaro, zvakasanganiswa nekuwedzera kukuru kwekugadzira mukota yechina uye kumanikidza kukuru kwekupa, zvinotarisirwa kuti PVC ichengetedze isina simba kushanda.
