India pakadali pano ndiye chuma chomwe chikukula kwambiri padziko lonse lapansi.Chifukwa cha chiwerengero chake chaching'ono komanso chiwerengero chochepa chodalira anthu, India ali ndi ubwino wake wapadera, monga chiwerengero chachikulu cha antchito aluso, ndalama zochepa zogwirira ntchito komanso msika waukulu wapakhomo.Pakali pano, India ali 32 chlor-alkali makhazikitsidwe ndi 23 chlor-alkali mabizinesi, makamaka ali kumwera chakumadzulo ndi kum'mawa kwa dziko, ndi okwana kupanga mphamvu matani 3.9 miliyoni mu 2019. M'zaka 10 zapitazi, kufunika kwa Soda wa caustic wakula ndi pafupifupi 4.4%, pomwe kufunikira kwa klorini kwakula pang'onopang'ono ndi 4.3%, makamaka chifukwa chakukula pang'onopang'ono kwamakampani ogwiritsira ntchito chlorine kunsi kwa mtsinje.

Misika yomwe ikubwera ikupita patsogolo

Malinga ndi momwe mafakitale akumayiko omwe akutukuka amagwirira ntchito, kufunikira kwa tsogolo la caustic soda kudzakula kwambiri makamaka ku Southeast Asia, Africa ndi South America.M'mayiko aku Asia, mphamvu ya caustic soda ku Vietnam, Pakistan, Philippines ndi Indonesia idzawonjezeka pang'onopang'ono, koma zochitika zonse za zigawozi zidzakhalabe zochepa.Makamaka, kukula kwa kufunikira kwa India kudzapitilira kukula kwa mphamvu, ndipo kuchuluka kwa zotengera kumayiko ena kudzawonjezeka.

Kuphatikiza apo, India, Vietnam, Indonesia, Malaysia, Thailand ndi madera ena akum'mwera chakum'mawa kwa Asia kuti asunge kufunikira kwakukulu kwa zinthu za chlor-alkali, kuchuluka kwakunja kwakunja kumawonjezeka pang'onopang'ono.Tengani msika waku India mwachitsanzo.Mu 2019, mphamvu yopanga PVC yaku India inali matani 1.5 miliyoni, zomwe zimawerengera pafupifupi 2.6% ya mphamvu zopanga padziko lonse lapansi.Kufuna kwake kunali pafupifupi matani 3.4 miliyoni, ndipo kuitanitsa kwake pachaka kunali pafupifupi matani 1.9 miliyoni.Pazaka zisanu zikubwerazi, zofuna za PVC za ku India zikuyembekezeka kukula ndi 6.5 peresenti kufika matani 4.6 miliyoni, ndipo zogula kuchokera kunja zikukula kuchokera ku matani 1.9 miliyoni kufika ku matani 3.2 miliyoni, makamaka kuchokera ku North America ndi Asia.

M'machitidwe ogwiritsira ntchito kunsi kwa mtsinje, mankhwala a PVC ku India amagwiritsidwa ntchito makamaka m'mafakitale a chitoliro, mafilimu ndi waya ndi chingwe, omwe 72% amafuna ndi mafakitale a chitoliro.Pakadali pano, kugwiritsa ntchito PVC kwa munthu ku India ndi 2.49kg poyerekeza ndi 11.4 kg padziko lonse lapansi.Kugwiritsa ntchito kwa PVC kwa munthu aliyense ku India kukuyembekezeka kukwera kuchoka pa 2.49kg kufika pa 3.3kg pazaka zisanu zikubwerazi, makamaka chifukwa cha kuchuluka kwa zinthu za PVC pomwe boma la India likukonzekera mapulani azachuma omwe akufuna kupititsa patsogolo chitetezo cha chakudya, nyumba. , zomangamanga, magetsi ndi madzi akumwa a anthu onse.M'tsogolomu, makampani a PVC aku India ali ndi kuthekera kwakukulu kwachitukuko ndipo adzakumana ndi mwayi watsopano.

Kufunika kwa soda ku Southeast Asia kukukulirakulira.Kukula kwapakati pachaka kwa aluminiyamu, ulusi wopangira, zamkati, mankhwala ndi mafuta ndi pafupifupi 5-9%.Kufunika kwa soda ku Vietnam ndi Indonesia kukukula mofulumira.Mu 2018, mphamvu yopanga PVC ku Southeast Asia inali matani 2.25 miliyoni, ndi chiwongola dzanja cha pafupifupi 90%, ndipo kufunikira kwakhalabe ndi kukula kwapachaka pafupifupi 6% m'zaka zaposachedwa.M'zaka zaposachedwa, pakhala pali mapulani angapo okulitsa kupanga.Ngati zopanga zonse zapangidwa, gawo lazofuna zapakhomo zitha kukwaniritsidwa.Komabe, chifukwa cha dongosolo lokhazikika lachitetezo cha chilengedwe, pali kusatsimikizika mu polojekitiyi.
