3. PVC ihinduka ryinyungu no guhitamo ingamba
Inyungu nubwubatsi byaganiriweho na PVC nkurugero.Icyiciro cya PVC cyo guhindura isoko gishingiye ku ngingo yavuzwe haruguru, kandi logique ya "valuation + driver" isesengurwa na logique ya "valuation + driver".Nkurwego rwo kugereranya inyungu, iyo inganda za PVC zo hanze zigeze kumwanya runaka winyungu (1000 hejuru), bivuze ko urwego rusange rwinyungu rwinganda ari rwiza, rushobora gukoreshwa nkigiciro kinini, ninganda itangira vuba ariko ibisabwa nibisabwa.Muri off -season, ibarura ryimurwa hepfo, kandi nyuma yo kubona hejuru, rikoreshwa nkicyiciro cyubusa.Iyo igihombo cya chlorine -alkali igihombo, ibigo byinshi muruganda birashobora gutakaza amafaranga nkigiciro gito.Muri iki gihe, umushoferi agomba kwitabwaho.Kubyingenzi bya PVC, ibisabwa muri rusange biratera imbere kandi kugenda byihuse.
Ariko, mubikorwa nyirizina, urashobora rwose guhura n "" agaciro gake + umushoferi hejuru "kugirango uhuze byinshi cyangwa" igiciro kinini + gutwara hasi "kugirango ujye mugihe cyo guhuza ikirere.Ingingo yavuzwe haruguru PVC kuva 2016 kugeza 2023 yari urugero.Kuva mu mwaka wa 2016 na 2020-2021, kwiyongera-guhamagarwa kwabaye byinshi muri macro-drives, harimo no guteza imbere inganda z’imitungo itimukanwa mu 2016, politiki y’ifaranga ridahwitse muri 2020, karubone itabogamye mu 2021. Muri icyo gihe icyarimwe , inyungu z'inganda zarazamutse.Igihombo cy’inganda cyiyongereye kuva muri Kamena 2022, ariko ku nkunga ya alkaline -gutwika inyungu, iyubakwa ry’inganda ntirigaragara, kandi ibyifuzo biterwa n’umutungo utimukanwa.Ntabwo buri gihe bigaragara, kandi isoko ikomeje kuba intege nke.Nubwo iri muburyo buke bwo kugereranya agaciro ariko nta modoka, igiciro cya PVC cyazamutse kurwego rwo hasi uyu mwaka.
Urebye kuri PVC y'ubu, inyungu z'amasosiyete ya PVC muri Shandong ni -800.Kuva muri Kamena umwaka ushize, yatakaje amafaranga.Inyungu ihuriweho na Shandong ni hafi-200.Uyu mwaka, wabaye mubihombo bito.Bitewe ninyungu yibiciro ninyungu mumajyaruguru yuburengerazuba, kugabanuka kwumusaruro mumajyaruguru yuburengerazuba ntabwo bigaragara.Mu gihembwe cya mbere cyuyu mwaka, habaye ibice 2-3 bishya byibikoresho bishya.Umusaruro wibarura ryinshi wakomeje umwaka ushize.Mu gihembwe cya mbere, iracyari mu isoko, bityo rero nubwo PVC iri mu giciro cyo hasi ugereranije, igiciro kiragoye gukora.Urebye kuri "valuation + driver", igiciro gito nikintu gihagije kugirango igiciro kizamuke mugihe kizaza aho kuba ibikenewe.Uyu mwaka PVC itwarwa nibisabwa.PVC ngufi -term izakomeza icyerekezo cyo guhindagurika.Muri Mata, kubaho kubungabunga icyi no gusaba gukira, bityo urashobora kugerageza umubare muto nibindi byinshi kubiciro biriho.
Vuga muri make
Inyungu izagira ingaruka kumyitwarire yikigo.Nka nganda zikora imiti, ibigo byo hejuru byibanze cyane.Mugihe gito, impinduka mubyunguka mugihe gito bizagira ingaruka kumyubakire yimbere.Inyungu yoherezwa kubiciro byarangiye mugutanga isoko.Iyo usubije amaso inyuma ukareba isoko yamateka hamwe na logique isanzwe "igenamigambi + umushoferi", igenamigambi mubisanzwe ni ibintu bihagije, kandi ingaruka nyinshi ku isoko ziri mubashoferi.Kwisubiraho bisubira mubisanzwe (kurugero, ikiguzi cyo gusana imbeho ni kinini, ikirahure ntikizakonja mugihe ikirahure cyatakaye, kandi uruhande rutanga ntiruzagabanuka ako kanya).Igihe kimwe, inganda ntabwo zunguka.Agaciro ko kugereranya ni uguhuza ishingiro ryibicuruzwa.Kurugero, mugihe cyo hejuru cyane yubwoko nka PVC, kumanuka bizagabanya kugura ibicuruzwa, kandi alkali isa nkikirahure cyo hasi irakenewe gusa.Ibikoresho fatizo ntibishobora guhagarika itangwa.Igihe ni kirekire).Mubyongeyeho, mugihe urebye igiciro, ugomba kwitondera inzira yibicuruzwa.Kurugero, kuri PVC, ubushobozi bwo kubyaza umusaruro amashanyarazi yo hanze afite ubushobozi buke bwo gukora.Uruhande rutanga ibintu rwateje ingaruka nini, kandi inganda zitakaza inyungu za chlorine -alkali inganda zahujwe zizahinduka.Mugihe uhisemo ingamba, igiciro gishobora koherezwa murimwe guhitamo.Birakenewe cyane kubona imbaraga za shoferi.Dufashe PVC nk'urugero, igenamigambi ryibikorwa byinshi ntabwo ryabaye hejuru mugutakaza igihombo.Ibisabwa, biteganijwe ko kugabanya umusaruro muri Mata no kwiyongera kubisabwa.Urebye inyungu nigihombo kuruta kureba inyungu nigihombo, umubare muto urashobora guhuzwa nigiciro kiriho.Wibande kumiterere yicyerekezo cya nyuma.bigarukira.
