Kutanthauzira kotentha kwa PVC: Kuchokera ku phindu lambiri, kusankha (2)

2. Phindu ndi kuyamba-kutenga PVC monga chitsanzo

Chithunzi chomwe chili pansipa chimasankha tsogolo la PVC ndi machitidwe a phindu kuyambira 2016 mpaka pano.Pakati pawo, phindu lasankha woimira Shandong kunja kwa -Shandong kunja kwa miyala yamtengo wapatali ndi phindu lophatikizana.Chifukwa cha ubwino wa chuma cha malasha, mtengo wake ndi wotsika kuposa wa East China.Ndikosavuta kuyimira phindu laling'ono lamakampani.Pakali pano, mphamvu zoweta electrone nkhani pafupifupi 80 %, ethylene mphamvu anayambitsa mlandu 20 %, ndi mabuku mphamvu yopanga klorini ndi za 70%.Popeza phindu la chlorine - alkali Integrated mabizinesi ndi apamwamba kwambiri kuposa phindu la kampani, East China kwenikweni ntchito ntchito East China ku mayiko akunja.Phindu la bizinesi ya PVC ya miyala yamagetsi ndi gawo lotsika kwambiri pamsika.Mwachitsanzo, kampani ya PVC ili ndi phindu, ndiye kuti malondawo ndi opindulitsa onse.Ngati mabizinesi aku East China ophatikizika a PVC ataya phindu, kupanga mabizinesi abwinobwino kungakhudzidwe.

Tikayang'ana kuyambira 2016 mpaka 2023, pamene phindu la makampani amagetsi kunja kwa East China linafika pafupifupi 1,000, linkatsagana ndi pamwamba pa msika, monga November 2016, September 2017, ndi October 2021. kupangidwa, kwenikweni kumatsagana ndi pansi, monga Januware 2016, Januware 2022, ndi Novembala 2022. Potengera nyengo yamakampani, PVC ili ndi zokonza ziwiri kawiri pachaka mu kasupe ndi autumn, motsatana kuyambira Epulo ndi June. July-September.Magawo atatu apamwamba ali pafupi ndi nyengo yokonza.Kusalinganizika kwapang'onopang'ono kwapang'onopang'ono ndi kufunikira kunabweretsa kukwera kwamitengo.Phindu lamakampani litakula, malondawo adakula mwachangu momwe angathere.Pambuyo pakuwonjezeka komanso kubwezeredwanso kunsi kwa nkhokwe kutsika, msika udayamba.Pamene kutayika kwa klorini-alkali kusakanikirana, makampaniwa adatsika pang'onopang'ono.Ngakhale kuti palibe kuyendera wamba pa siteji iyi, ndi pa mlingo wotsika nthawi yomweyo.M'mawu ena, kumanga phindu ndi kutenga "V" mtundu.Pamene kutayika, kumangako ndi "inverted", ndipo phindu limagwirizana bwino

Chifukwa unyolo wamakampani a PVC umakhala wophatikizika kwambiri, zida zina ziyenera kuganiziridwa mozama pokambirana za phindu la PVC.Zina mwa izo, zomwe zimakhudzidwa kwambiri ndizomwe zimapangidwira kumtunda ndi alkali yazinthu zomwe zikutsatiridwa.Pakalipano, mphamvu yopangira Corporal Method ndi yaikulu, choncho mtengo wa miyala yamagetsi ndi PVC umagwirizana kwambiri.Nthawi zambiri, mitengo ya PVC yakwera ndi mtengo wa miyala yamagetsi.2021 ndi chaka chapadera kwambiri.Zimakhudzidwa ndi mphamvu zonse ziwiri.Kutsika kwa miyala yamagetsi kumakhala kolimba, ndipo mtengo wa miyala yamagetsi wakwera.Kwa makampani opanga magetsi a PVC odzinyamula okha, chidwi choyambira chimakhala chokwera.Panthawiyi, phindu limapezeka makamaka ndi fakitale ya electrone (fakitale yamagetsi yodzisungira yokha imatha kuwonjezera phindu la PVC kupyolera mwa phindu la mwala wamagetsi), kotero zikhoza kuwoneka kuti zikhoza kuwoneka. Ngakhale mtengo wa PVC udapitilirabe kutsika mtengo mu 2021, phindu lamakampani a PVC lamakampani a PVC nthawi zambiri limataya ndalama.Gawo ili la bizinesi lachepetsa kupanga kapena kukonza.Kuonjezerapo Nthawi yomweyo ya nthawi yomweyi ndi yochepa.

Pulasitiki Kunja Pvc Mapepala 

Mtengo wa alkali alkali umakhudzanso kwambiri kamangidwe ka makampani a PVC.Nthawi zambiri, 1 tani PVC imatsagana ndi matani 0.7-0.8 amchere.Phindu pakati pawo lakhudzana wina ndi mzake.Kugwa, kampani ya PVC yayamba kale kutayika, koma panthawiyi ntchito yamakampaniyi sinakhudzidwe kwambiri.Mpaka Julayi, mtengo wa alkaline pyrine wagwa, kuchititsa kutayika kwa phindu kwa kampani yophatikizika ya chlorine ndi alkali.Msika wa PVC ubwereranso.Pofika Novembala 2022, alkali ya alkali idachepetsedwa pang'ono, ndipo phindu lonse la chlorine -alkali linali kutaya ndalama.Mu March, mtengo wa zamchere wokazinga unatsika kwambiri, ndipo kuwonongeka kwa klorini -alkali Integrated kunakula kwambiri.Pamene nyengo yokonza yatsala pang’ono kulowa, tingaone kuti nthawi yoyambira chaka chino ndi yoyambirira kuposa zaka zam’mbuyo.

Kawirikawiri, kwa makampani opanga mankhwala, kumtunda kudzasinthidwa malinga ndi phindu la nthawi yeniyeni, ndipo kugawanika kwapang'onopang'ono ndi zofunikira zidzasinthidwa ndikukhudzidwa ndi kupezeka.Panthawi imodzimodziyo, kufufuza phindu kuyenera kuphatikizidwa ndi ndondomeko ya mafakitale.Kutengera PVC mwachitsanzo, iyenera kugawidwa m'magulu ophatikizana komanso osaphatikizidwa.Kuphatikiza apo, ndikofunikira kuphatikiza phindu la mwala ndi zamchere.Kuphatikiza apo, bizinesi yosonkhanitsira magetsi yapeza phindu linalake monga gawo lapamwamba lamakampani, ndipo zotayika zamabizinesi ophatikizika zili mumakampani.Panthawi imodzimodziyo, iyeneranso kuganiziridwa pamodzi ndi zinthu zina.
