izindaba

I-India njengamanje ingumnotho okhula ngokushesha kakhulu emhlabeni.Ngenxa yabantu bayo abasha kanye nezinga eliphansi lokuncika emphakathini, i-India inezinzuzo zayo eziyingqayizivele, njengenani elikhulu labasebenzi abanamakhono, izindleko eziphansi zabasebenzi kanye nemakethe enkulu yasekhaya.Njengamanje, i-India inokufakwa kwe-chlor-alkali engama-32 kanye namabhizinisi angama-chlor-alkali angama-23, ikakhulukazi atholakala eningizimu-ntshonalanga nasempumalanga yezwe, enamandla okukhiqiza amathani ayizigidi ezi-3.9 ngo-2019. Eminyakeni eyi-10 edlule, isidingo i-caustic soda ikhule cishe ngo-4.4%, kanti isidingo se-chlorine sikhule ngokuncipha ngo-4.3%, ikakhulukazi ngenxa yokuthuthuka kancane kwemboni yokusetshenziswa kwe-chlorine engezansi.

Izimakethe ezisafufusa ziyadlondlobala

Ngokwesakhiwo samanje sezimboni zamazwe asathuthuka, isidingo sesikhathi esizayo se-caustic soda sizokhula ngokushesha ikakhulukazi eNingizimu-mpumalanga ye-Asia, e-Afrika naseNingizimu Melika.Emazweni ase-Asia, amandla e-caustic soda eVietnam, ePakistan, ePhilippines nase-Indonesia azokhula ngezinga elithile, kodwa isimo sonke salezi zifunda sizohlala sishoda.Ikakhulukazi, ukukhula kwesidingo saseNdiya kuzodlula ukukhula kwamandla, futhi umthamo wokungenisa uzokwanda.

Ngaphezu kwalokho, i-India, Vietnam, Indonesia, Malaysia, Thailand kanye nezinye izifunda zaseNingizimu-mpumalanga ye-Asia ukugcina isidingo esinamandla semikhiqizo ye-chlor-alkali, umthamo wokungenisa wendawo uzokhula kancane kancane.Thatha imakethe yaseNdiya njengesibonelo.Ngo-2019, umthamo wokukhiqiza we-PVC waseNdiya wawungamathani ayizigidi eziyi-1.5, okubalelwa ku-2.6% wamandla okukhiqiza emhlabeni jikelele.Isidingo sayo sasicishe sibe ngamathani ayizigidi ezi-3.4, kanti ukungenisa kwayo ngonyaka kwakungamathani ayizigidi eziyi-1.9.Eminyakeni emihlanu ezayo, isidingo sePVC saseNdiya kulindeleke ukuthi sikhule ngamaphesenti angu-6.5 siye kumathani ayizigidi ezingu-4.6, kanti ukuthengwa kwamanye amazwe kuzokhula kusuka kumathani ayizigidi ezingu-1.9 kuya kumathani ayizigidi ezingu-3.2, ikakhulukazi eNyakatho Melika nase-Asia.

Esakhiweni sokusetshenziswa komfula, imikhiqizo ye-PVC eNdiya isetshenziswa kakhulu ezimbonini zamapayipi, ifilimu nezintambo kanye nezintambo, lapho i-72% yazo idingeka imboni yamapayipi.Njengamanje, ukusetshenziswa kwe-PVC yomuntu ngamunye eNdiya kungu-2.49kg uma kuqhathaniswa ne-11.4 kg emhlabeni jikelele.Ukusetshenziswa kwe-PVC ngomuntu ngamunye eNdiya kulindeleke ukuthi kukhuphuke kusuka ku-2.49kg kuye ku-3.3kg kule minyaka emihlanu ezayo, ikakhulukazi ngenxa yokwanda kwesidingo semikhiqizo ye-PVC njengoba uhulumeni waseNdiya eqinisa izinhlelo zokutshala izimali ezihloselwe ukuthuthukisa ukuhlinzekwa kokuphepha kokudla, izindlu. , ingqalasizinda, ugesi namanzi okuphuza omphakathi.Ngokuzayo, imboni ye-PVC yaseNdiya inamandla amakhulu okuthuthuka futhi izobhekana namathuba amaningi amasha.

Isidingo se-caustic soda eNingizimu-mpumalanga ye-Asia sikhula ngokushesha.Isilinganiso sonyaka sokukhula kwe-alumina ezansi nomfula, imicu yokwenziwa, i-pulp, amakhemikhali namafutha cishe singama-5-9%.Isidingo sesoda eqinile eVietnam nase-Indonesia sikhula ngokushesha.Ngo-2018, umthamo wokukhiqiza we-PVC eNingizimu-mpumalanga ye-Asia wawungamathani ayizigidi ezingu-2.25, nesilinganiso sokusebenza esingaba ngu-90%, futhi isidingo silondoloze izinga lokukhula lonyaka cishe ngo-6% eminyakeni yamuva.Eminyakeni yamuva nje, kube nezinhlelo eziningana zokwandisa ukukhiqiza.Uma wonke umkhiqizo ufakwa ekukhiqizeni, ingxenye yesidingo sasekhaya ingahlangatshezwana nayo.Kodwa-ke, ngenxa yohlelo oluqinile lokuvikela imvelo endaweni, kukhona ukungaqiniseki kuphrojekthi.
