Parizvino, zvese zviri zviviri PVC pachayo uye kumusoro kwekarusiyamu carbide zviri mune zvakati wandei.Tichitarisira kuna 2022 na 2023, nekuda kweiyo PVC indasitiri yakakwira simba rekushandisa zvivakwa uye matambudziko ekurapa chlorine, zvinotarisirwa kuti hazvisi zvakawanda zvigadziriso zvichaiswa mukugadzira.Iyo PVC indasitiri inogona kupinda yakasimba kutenderera kwenguva yakareba se3-4 makore.
Musika wecalcium carbide unoramba uchivandudza
Calcium carbide iindasitiri inotora simba rakawanda, uye zvakatemwa zvecalcium carbide furnaces kazhinji 12500KVA, 27500KVA, 30000KVA, uye 40000KVA.Calcium carbide furnaces pazasi 30000KVA mabhizinesi anorambidzwa nehurumende.Iyo yazvino mutemo yakapihwa neInner Mongolia ndeye: akanyura arc furnaces pazasi 30000KVA, musimboti, ese anobuda pamberi pekupera kwa2022;vanokwanisa vanogona kushandisa kudzoreredza kudzoreredza simba pa1.25:1.Zvinoenderana nenhamba dzemunyori, indasitiri yenyika yecalcium carbide ine huwandu hwekugadzira 2.985 miriyoni matani pazasi 30,000 KVA, inoverengera 8.64%.Mafurnace ari pasi pe30,000KVA muInner Mongolia anosanganisira kugadzirwa kwe800,000 matani, achiverengera 6.75% yehuwandu hwekugadzira huwandu muInner Mongolia.
Parizvino, purofiti yecalcium carbide yakakwira kusvika kunhoroondo dzakakwirira, uye kupihwa kwecalcium carbide kuri kushomeka.Chiyero chekushanda checalcium carbide furnaces chaifanira kuramba chakakwira, asi nekuda kwekukanganisa kwepolicy, mwero wekushanda hauna kukwira asi waramba.Indasitiri yePVC yakadzika zvakare ine chiyero chepamusoro chekushanda nekuda kwepurofiti yayo, uye pane kudiwa kwakasimba kwecalcium carbide.Tichitarisa kumberi, chirongwa chekutanga kugadzirwa kwe calcium carbide chinogona kumiswa nekuda kwe "carbon neutrality".Izvo zvine chokwadi chekuti Shuangxin's 525,000-ton plant inotarisirwa kuiswa mukushanda muhafu yechipiri yegore rino.Iye munyori anotenda kuti kuchave nekumwe kutsiva kwePVC kugadzirwa kwesimba mune ramangwana uye hazvizounza kutsva kwekuwedzera kwekupa.Zvinotarisirwa kuti calcium carbide industry ichange iri mubhizimusi mumakore mashomanana anotevera, uye mitengo yePVC icharamba yakakwirira.
Global new supply yePVC yakaderera
PVC iindasitiri inotora simba rakawanda, uye yakakamurwa kuita zvemahombekombe ethylene process midziyo uye inland calcium carbide process michina muChina.Nhamba yepamusoro yekugadzirwa kwePVC yaive muna 2013-2014, uye kukura kwehuwandu hwekugadzira hwaive hwakanyanya, zvichikonzera kuwandisa mu2014-2015, kurasikirwa kweindasitiri, uye huwandu hwese hwekushanda hwakadzika kusvika 60%.Parizvino, PVC kugadzirwa kwesimba kwatama kubva kune yakawedzera kutenderera kuenda kune yebhizinesi kutenderera, uye iyo yepamusoro yekushanda mwero iri pedyo ne90% yenhoroondo yakakwirira.
Zvinofungidzirwa kuti kushoma kwePVC kugadzirwa kwepamba kuchaiswa mukugadzirwa muna 2021, uye huwandu hwekukura kwepagore huchangoita 5% chete, uye zvinonetsa kudzikisira kusimba.Nekuda kwekusamira kuri kuda panguva yeMutambo weChirimo, PVC parizvino iri kuunganidza mwaka nemwaka, uye nhanho yekuverenga iri padanho rakarerekera gore negore.Zvinotarisirwa kuti mushure mekuda kunotangazve kuderedza muhafu yekutanga yegore, PVC inventory icharamba yakaderera kwenguva yakareba muhafu yechipiri yegore.
Kubva 2021, Inner Mongolia haichatenderi mapurojekiti matsva ekuita senge coke (blue charcoal), calcium carbide, uye polyvinyl chloride (PVC).Kana kuvaka kuchidikanwa, huwandu hwekugadzira uye kudzoreredza kushandiswa kwesimba kunofanirwa kuitwa mudunhu.Zvinotarisirwa kuti hapana itsva calcium carbide nzira yePVC yekugadzira inozoiswa mukugadzira kunze kwekunge yakarongwa kugadzirwa kwesimba.
Kune rimwe divi, chiyero chekukura kwemhiri kwemakungwa PVC kugadzirwa kwakadzikira kubva 2015, neavhareji yekukura isingasviki 2%.Muna 2020, iyo yekunze dhisiki ichapinda yakasimba yekugovera chiyero mamiriro.Yakaiswa pamusoro pekukanganisa kwechamupupuri cheUS mukota yechina ye2020 uye kutonhora kwemhepo muna Ndira 2021, mhiri kwemakungwa mitengo yePVC yakakwira kusvika kunhoroondo dzakakwirira.Kana ichienzaniswa nemitengo yemhiri kwemakungwa PVC, PVC yemumba haina kushomeka, ine purofiti yekunze inosvika 1,500 yuan/ton.Makambani emudzimba akatanga kuwana nhamba huru yeodha dzekunze kubva muna Mbudzi 2020, uye PVC yachinja kubva pane dzakasiyana siyana dzinoda kutengwa kunze kwenyika kuenda kune dzakasiyana siyana kunze kwenyika.Zvinotarisirwa kuti pachave nemaodha ekutengesa kunze kwenyika mukota yekutanga ye2021, izvo zvawedzera kusimba kwemukati PVC mamiriro ekupa.
Muchiitiko ichi, mutengo wePVC uri nyore kukwira asi zvakaoma kudonha.Iko kupokana kukuru panguva ino ndiko kupokana pakati pePVC yemutengo wepamusoro uye purofiti yakadzika.Zvigadzirwa zvekudzika pasi kazhinji zvine mutengo wakaderera.Kana PVC yemutengo wepamusoro-isingakwanise kufambiswa zvakanaka kuenda kuzasi, zvinozokanganisa kudzika kwekutanga-ups uye maodha.Kana zvigadzirwa zvepasi zvichigona kukwidza mitengo kazhinji, mitengo yePVC inogona kuramba ichikwira.
