Txhawm rau txhawb kev txhim kho ntawm cov qauv kev lag luam ntawm chlor-alkali kev lag luam thiab tswj kev txhim kho kev lag luam, raws li cov qauv kev tsim kho kom ruaj khov ntawm "optimizing cov txheej txheem, kev tsim kho kom zoo, kho cov qauv, txuag hluav taws xob, tiv thaiv ib puag ncig. , kev nyab xeeb kev tsim khoom, thiab kev ua haujlwm thev naus laus zis", National Development thiab Reform Commission tau tsim thiab muab "Chlor-alkali (Caustic soda, polyvinyl chloride) kev lag luam nkag mus rau cov xwm txheej", thiab nws tau siv txij lub Kaum Ob Hlis 1, 2007: Hais txog kev lag luam. layout, tshiab chlor-alkali ntau lawm tuam txhab uas muag yuav tsum tau nyob ze rau lub hauv paus chiv keeb ntawm cov peev txheej thiab lub zog. Tshiab tsim calcium carbide txoj kev polyvinyl chloride qhov project thiab nws txhawb nqa caustic soda project; Nyob rau hauv cov nqe lus ntawm kev siv tshuab, nws yuav tsum tau tsim cov calcium carbide slag kev siv cov cuab yeej xws li calcium carbide slag cement los ua calcium carbide slag kev siv cov khoom siv tib lub sijhawm. Kev nkag mus tau kuj yog raws li qhov ntsuas kev siv hluav taws xob thiab ib puag ncig teeb tsa tus qauv rau cov haujlwm tshiab. Kev hloov kho ntawm txoj cai kev lag luam tau nce qhov pib ntawm peev, thev naus laus zis, txuj ci thiab cov peev txheej hauv kev lag luam chlor-alkali.
