Tam sim no, ob qho tib si PVC nws tus kheej thiab cov khoom siv calcium carbide yog nyob rau hauv cov khoom siv nruj heev.Nrhiav rau pem hauv ntej rau 2022 thiab 2023, vim PVC kev lag luam tus kheej lub zog siv zog thiab cov teeb meem tshuaj chlorine, nws xav tias tsis muaj ntau qhov kev teeb tsa yuav raug muab tso rau hauv ntau lawm.Kev lag luam PVC tuaj yeem nkag mus rau lub voj voog muaj zog ntev li 3-4 xyoos.
Kev lag luam calcium carbide tseem txhim kho
Calcium carbide yog kev lag luam uas siv hluav taws xob ntau, thiab cov ntsiab lus ntawm calcium carbide furnaces feem ntau yog 12500KVA, 27500KVA, 30000KVA, thiab 40000KVA.Calcium carbide furnaces qis dua 30000KVA yog lub xeev txwv kev lag luam.Txoj cai tshiab tshaj tawm los ntawm Inner Mongolia yog: submerged arc furnaces hauv qab 30000KVA, hauv paus ntsiab lus, txhua qhov tawm ua ntej kawg ntawm 2022;Cov neeg tsim nyog tuaj yeem siv qhov kev hloov pauv hloov ntawm 1.25: 1.Raws li tus sau phau ntawv txheeb cais, lub teb chaws calcium carbide kev lag luam muaj peev xwm ntau lawm ntawm 2.985 lab tons hauv qab 30,000 KVA, accounting rau 8.64%.Lub tshuab hluav taws xob qis dua 30,000KVA hauv Inner Mongolia koom nrog lub peev xwm ntawm 800,000 tons, suav txog 6.75% ntawm tag nrho cov peev txheej tsim tawm hauv Inner Mongolia.
Tam sim no, cov txiaj ntsig ntawm calcium carbide tau nce mus rau keeb kwm siab, thiab cov khoom siv calcium carbide tsis txaus.Kev khiav hauj lwm tus nqi ntawm calcium carbide furnaces yuav tsum nyob twj ywm siab, tab sis vim muaj kev cuam tshuam txoj cai, tus nqi khiav hauj lwm tsis tau nce tab sis tsis kam.Kev lag luam hauv qab PVC kuj tseem muaj kev ua haujlwm siab vim nws cov txiaj ntsig zoo, thiab muaj kev xav tau ntawm calcium carbide.Saib ua ntej, txoj kev npaj pib tsim cov calcium carbide yuav raug ncua vim "carbon neutrality".Nws yog qhov tseeb tias Shuangxin 525,000-tuj cog yuav tsum tau muab tso rau hauv kev ua haujlwm hauv ib nrab xyoo no.Tus kws sau ntawv ntseeg tias yuav muaj kev hloov pauv ntawm PVC ntau lawm yav tom ntej thiab yuav tsis coj cov khoom siv tshiab ntxiv.Nws cia siab tias kev lag luam calcium carbide yuav nyob rau hauv lub voj voog ua lag luam nyob rau ob peb xyoos tom ntej no, thiab cov nqi PVC yuav nyob twj ywm siab.
Ntiaj teb no cov khoom tshiab ntawm PVC yog tsawg
PVC yog ib qho kev lag luam uas siv hluav taws xob ntau, thiab nws tau muab faib ua cov txheej txheem dej hiav txwv ethylene thiab cov khoom siv hauv av calcium carbide hauv Suav teb.Lub ncov ntawm PVC ntau lawm yog nyob rau hauv 2013-2014, thiab kev loj hlob tus nqi ntawm ntau lawm muaj peev xwm kuj siab, ua rau overcapacity nyob rau hauv 2014-2015, kev lag luam poob, thiab tag nrho cov kev khiav hauj lwm tus nqi poob mus rau 60%.Tam sim no, PVC muaj peev xwm ntau lawm tau txav los ntawm lub voj voog ntau dhau mus rau lub voj voog ua lag luam, thiab qhov kev khiav hauj lwm nce mus txog 90% ntawm cov keeb kwm siab.
Nws tau kwv yees tias tsawg dua cov khoom siv PVC hauv tsev yuav raug muab tso rau hauv kev tsim khoom hauv xyoo 2021, thiab qhov kev loj hlob ntawm cov khoom lag luam txhua xyoo tsuas yog kwv yees li 5%, thiab nws nyuaj rau txo cov khoom nruj.Vim tias qhov kev xav tau ruaj khov thaum lub caij nplooj ntoos hlav Festival, PVC tam sim no sib sau ua ke raws caij nyoog, thiab cov khoom muag qib yog nyob rau theem nruab nrab xyoo-rau-xyoo.Nws cia siab tias tom qab qhov kev thov rov pib dua rau cov khoom lag luam hauv thawj ib nrab ntawm lub xyoo, PVC cov khoom muag yuav nyob qis rau lub sijhawm ntev hauv ib nrab xyoo.
Txij xyoo 2021, Inner Mongolia yuav tsis pom zoo cov peev txheej tshiab xws li coke (xiav charcoal), calcium carbide, thiab polyvinyl chloride (PVC).Yog tias kev tsim kho tsim nyog tiag tiag, kev tsim khoom muaj peev xwm thiab kev siv hluav taws xob txo qis yuav tsum tau ua nyob rau hauv cheeb tsam.Nws cia siab tias tsis muaj cov txheej txheem calcium carbide tshiab PVC yuav raug muab tso rau hauv kev tsim khoom tshwj tsis yog rau kev npaj muaj peev xwm.
Ntawm qhov tod tes, qhov kev loj hlob ntawm txawv teb chaws PVC muaj peev xwm tau poob qis txij li xyoo 2015, nrog qhov kev loj hlob nruab nrab ntawm tsawg dua 2%.Hauv 2020, sab nraud disk yuav nkag mus rau qhov sib npaug ntawm cov khoom siv nruj.Superimposed ntawm qhov cuam tshuam los ntawm Teb Chaws Asmeskas nag xob nag cua nyob rau lub quarter thib plaub ntawm 2020 thiab cua txias nthwv dej thaum Lub Ib Hlis 2021, cov nqi PVC txawv teb chaws tau nce mus rau keeb kwm siab.Piv nrog rau txawv teb chaws PVC nqi, domestic PVC kuj underestimated, nrog ib tug export profit ntawm 1,500 yuan / tuj.Cov tuam txhab lag luam hauv tsev tau pib tau txais ntau qhov kev txiav txim xa tawm txij lub Kaum Ib Hlis 2020, thiab PVC tau hloov pauv los ntawm ntau yam uas yuav tsum tau xa mus rau ntau yam khoom xa tawm.Nws cia siab tias yuav muaj kev txiav txim rau kev xa tawm hauv thawj peb lub hlis twg ntawm xyoo 2021, uas tau ua rau muaj kev kub ntxhov hauv tsev PVC khoom.
Nyob rau hauv cov ntaub ntawv no, tus nqi ntawm PVC yog ib qho yooj yim mus nce tab sis nyuaj rau poob.Qhov kev tsis sib haum xeeb tseem ceeb tam sim no yog qhov tsis sib xws ntawm cov nqi siab PVC thiab cov txiaj ntsig qis qis.Cov khoom lag luam hauv qab feem ntau muaj tus nqi qis dua.Yog tias tus nqi siab PVC tsis tuaj yeem kis tau yooj yim mus rau hauv qab, nws yuav ua rau muaj kev cuam tshuam rau kev pib pib thiab kev txiav txim.Yog tias cov khoom lag luam qis tuaj yeem nce nqi ib txwm, PVC nqi yuav nce ntxiv.
