Makampani a chlor-alkali ndi makampani ofunikira kwambiri amankhwala, ndipo zinthu zazikulu zomwe zimayimira ndi caustic soda ndi polyvinyl chloride (PVC).

soda

Kumapeto kwa 2020, padziko lonse lapansi kupanga mphamvu koloko anafika matani 99.959 miliyoni, ndi mphamvu yopanga caustic koloko ku China anafika matani miliyoni 44,7, mlandu 44,7% ya mphamvu okwana kupanga dziko, kusanja woyamba mu dziko kupanga. mphamvu.

Pofika m'chaka cha 2020, kugawa kwa msika wa caustic soda kudziko langa kwadziwika pang'onopang'ono, makamaka kumadera atatu a North China, Northwest China ndi East China.Magawo atatu omwe ali pamwambapa 'caustic soda' amapanga mphamvu yoposa 80% ya mphamvu zonse zopangira dziko.Pakati pawo, chiwerengero cha dera limodzi kumpoto kwa China chinapitirizabe kuwonjezeka, kufika pa 37,40%.Mphamvu yopanga koloko ya caustic kum'mwera chakumadzulo kwa China, South China ndi kumpoto chakum'mawa kwa China ndizochepa, ndipo gawo la mphamvu zopanga zonse m'dera lililonse ndi 5% kapena zochepa.

Zithunzi za PVC

PVC, kapena polyvinyl chloride, inali pulasitiki yayikulu kwambiri padziko lonse lapansi ndipo idagwiritsidwa ntchito kwambiri.Pakalipano, pali misika iwiri ikuluikulu yogula PVC m'dziko langa: zinthu zolimba ndi zofewa.zolimba mankhwala makamaka zosiyanasiyana mbiri, mapaipi, mbale, mapepala okhwima ndi kuwombera akamaumba mankhwala, etc.;zofewa makamaka mafilimu, mawaya ndi zingwe, zikopa yokumba, zokutira nsalu, payipi zosiyanasiyana, magolovesi, zidole, zofunda pansi pa zolinga zosiyanasiyana zipangizo, nsapato pulasitiki, ndi zokutira ena apadera ndi zosindikizira, etc.

Kuchokera pamalingaliro akufunika, m'zaka zaposachedwa, kufunikira kwa utomoni wa PVC m'dziko langa kwachulukirachulukira.Mu 2019, kugwiritsidwa ntchito kwa PVC resin ku China kudafika matani 20.27 miliyoni, kuwonjezeka kwa chaka ndi 7.23%.Ndikugwiritsa ntchito kosiyanasiyana kwa utomoni wa polyvinyl chloride, tikuyembekezeka kuti kumwa kwa polyvinyl chloride resin m'dziko langa kudzafika matani 22.109 miliyoni mu 2021, ndipo chiyembekezo chamsika ndi chachikulu.

Chidule cha Makampani a Chlor-Alkali

The dongosolo la unyolo mafakitale ndi ntchito diaphragm njira kapena ionic nembanemba njira electrolyze mchere madzi kupeza chlorine zopangira, ndipo nthawi yomweyo co-kupanga koloko caustic, ndi chlorine mpweya ntchito monga zopangira PVC. kupanga.

Malinga ndi kayendetsedwe kazachuma, makampani a chlor-alkali amakhudzidwa kwambiri ndi momwe chuma chikuyendera.Pamene chuma chambiri chikuyenda bwino, makampani a chlor-alkali amayendetsedwa ndi kugwiritsidwa ntchito ndipo amakula mofulumira;chuma chambiri chikatsika, kufunikira kwamakampani a chlor-alkali kumachepa, ngakhale kukhudzidwa kwapang'onopang'ono kumakhala kocheperako., koma zomwe zikuchitika pamakampani a chlor-alkali kwenikweni zimagwirizana ndi chuma chambiri.

Ndi chitukuko chofulumira chachuma chambiri cha dziko langa komanso kufunikira kwamphamvu kwa msika wogulitsa nyumba, "PVC + caustic soda" yothandizira makampani amtundu wa chlor-alkali mdziko langa yakula kwambiri, ndipo mphamvu zopanga ndi zotulutsa zakhala zikutuluka. kukula mofulumira.dziko langa lasanduka dziko lofunika kwambiri padziko lonse lapansi kupanga ndi ogula mankhwala chlor-alkali.
