Njengamanje, kokubili i-PVC ngokwayo kanye ne-calcium carbide ekhuphuka nomfula zitholakala ngokulingana.Uma sibheke ngabomvu ku-2022 no-2023, ngenxa yezakhiwo zemboni ye-PVC ezisebenzisa kakhulu amandla kanye nezinkinga zokwelapha i-chlorine, kulindeleke ukuthi kungabi kuningi okuzofakwa ekukhiqizeni.Imboni ye-PVC ingangena emjikelezweni onamandla iminyaka emi-3-4.
Imakethe ye-calcium carbide iyaqhubeka nokuba ngcono
I-Calcium carbide iyimboni edla amandla amaningi, futhi imininingwane yeziko le-calcium carbide ngokuvamile i-12500KVA, 27500KVA, 30000KVA, kanye ne-40000KVA.Amaziko e-calcium carbide angaphansi kuka-30000KVA angamabhizinisi akhawulelwe uhulumeni.Inqubomgomo yakamuva ekhishwe yi-Inner Mongolia ithi: amafurnace angaphansi kwamanzi angaphansi kuka-30000KVA, ngokomgomo, wonke aphuma ngaphambi kokuphela kuka-2022;abafanelekayo bangasebenzisa ukushintshwa kokunciphisa umthamo ku-1.25:1.Ngokwezibalo zombhali, imboni kazwelonke ye-calcium carbide inamandla okukhiqiza amathani ayizigidi ezingu-2.985 ngaphansi kwe-30,000 KVA, ehlanganisa i-8.64%.Amafurnace angaphansi kuka-30,000KVA e-Inner Mongolia afaka umthamo wokukhiqiza amathani angu-800,000, okubalelwa ku-6.75% yenani eliphelele lokukhiqiza e-Inner Mongolia.
Njengamanje, inzuzo ye-calcium carbide ikhuphuke yaba phezulu emlandweni, futhi ukunikezwa kwe-calcium carbide kuyashoda.Izinga lokusebenza kweziko le-calcium carbide bekufanele lihlale liphezulu, kodwa ngenxa yemithelela yenqubomgomo, izinga lokusebenza alizange likhuphuke kodwa lehlile.Imboni ye-PVC engezansi nayo inezinga eliphezulu lokusebenza ngenxa yenzuzo yayo enenzuzo, futhi kunesidingo esinamandla se-calcium carbide.Uma sibheka phambili, uhlelo lokuqala ukukhiqizwa kwe-calcium carbide lungahlehliswa ngenxa “yokungathathi hlangothi kwekhabhoni”.Kuqinisekile ukuthi isitshalo sikaShuangxin esingamathani angama-525,000 kulindeleke ukuthi siqale ukusebenza engxenyeni yesibili yalo nyaka.Umbhali ukholelwa ukuthi kuzoba nokushintshwa okwengeziwe komthamo wokukhiqiza we-PVC esikhathini esizayo futhi ngeke kulethe ukukhuphuka kokunikezwa okusha.Kulindeleke ukuthi imboni ye-calcium carbide izoba semjikelezweni webhizinisi eminyakeni embalwa ezayo, futhi amanani e-PVC azohlala ephezulu.
Ukunikezwa okusha komhlaba wonke kwe-PVC kuphansi
I-PVC iyimboni edla amandla amaningi, futhi ihlukaniswe ngemishini yenqubo ye-ethylene yasogwini kanye nemishini yenqubo ye-calcium carbide ephakathi nezwe e-China.Isilinganiso esiphezulu sokukhiqizwa kwe-PVC sasiku-2013-2014, futhi izinga lokukhula kwamandla okukhiqiza laliphezulu kakhulu, okuholela ekubeni namandla ngokweqile ngo-2014-2015, ukulahlekelwa yizimboni, futhi izinga lokusebenza jikelele lehle lafika ku-60%.Njengamanje, amandla okukhiqiza e-PVC asukile emjikelezweni oyinsalela kuya emjikelezweni webhizinisi, futhi izinga lokusebenza elikhuphuka nomfula liseduze no-90% wokuphakama komlando.
Kulinganiselwa ukuthi ukukhiqizwa kwe-PVC yasekhaya okumbalwa kuzofakwa ekukhiqizweni ngo-2021, futhi izinga lokukhula kokuhlinzekwa konyaka lizoba cishe ku-5% kuphela, futhi kunzima ukunciphisa ukunikezwa okuqinile.Ngenxa yesidingo esimile ngesikhathi soMkhosi Wasentwasahlobo, i-PVC njengamanje iqongelela ngezikhathi ezithile zonyaka, futhi izinga lokusungula lisezingeni elingathathi hlangothi unyaka nonyaka.Kulindeleke ukuthi ngemva kokuba isidingo siqale kabusha ukwehlisa isitokwe engxenyeni yokuqala yonyaka, i-inventory ye-PVC izohlala iphansi isikhathi eside engxenyeni yesibili yonyaka.
Kusukela ngo-2021, i-Inner Mongolia ngeke isagunyaza amaphrojekthi wamandla amasha afana ne-coke (amalahle aluhlaza), i-calcium carbide, ne-polyvinyl chloride (PVC).Uma ukwakhiwa kuyadingeka ngempela, umthamo wokukhiqiza kanye nokushintshwa kokunciphisa ukusetshenziswa kwamandla kufanele kusetshenziswe esifundeni.Kulindeleke ukuthi kungabikho indlela entsha ye-calcium carbide umthamo wokukhiqiza we-PVC ozofakwa ekukhiqizeni ngaphandle kwamandla okukhiqiza ahleliwe.
Ngakolunye uhlangothi, izinga lokukhula kwamandla okukhiqiza we-PVC phesheya lehlile kusukela ngo-2015, ngesilinganiso sokukhula esingaphansi kuka-2%.Ngo-2020, idiski yangaphandle izongena esimweni esiqinile sokunikezwa kwebhalansi.Njengoba ibekwe phezulu kumthelela wesiphepho sase-US engxenyeni yesine ka-2020 kanye negagasi elibandayo ngoJanuwari 2021, izintengo ze-PVC zaphesheya zikhuphuke zaba phezulu kakhulu emlandweni.Uma kuqhathaniswa namanani ePVC aphesheya kwezilwandle, i-PVC yasekhaya ibukelwa phansi, ngenzuzo yokuthekelisa engu-1,500 yuan/ton.Izinkampani zasekhaya zaqala ukuthola inqwaba yama-oda wokuthekelisa kusukela ngoNovemba 2020, futhi i-PVC isishintshile isuka ezinhlobonhlobo ezidinga ukuthunyelwa kwamanye amazwe iye kwinani eliphelele lokuthumela ngaphandle.Kulindeleke ukuthi kube nama-oda okuthunyelwa kwamanye amazwe ngekota yokuqala ka-2021, okukhulise isimo esiqinile sokuhlinzekwa kwe-PVC yasekhaya.
Kulokhu, intengo ye-PVC kulula ukukhuphuka kodwa kunzima ukuwa.Ukuphikisana okuyinhloko okwamanje ukungqubuzana phakathi kwe-PVC enenani eliphezulu kanye nenzuzo ephansi.Imikhiqizo ye-downstream ngokuvamile inokwenyuka kwentengo okuhamba kancane.Uma i-PVC enenani eliphezulu ingakwazi ukudluliselwa ngokushelela ezansi nomfula, nakanjani izophazamisa ukuqaliswa komfula kanye nama-oda.Uma imikhiqizo ephansi ingakhuphula izintengo ngokujwayelekile, izintengo ze-PVC zingaqhubeka nokukhuphuka.
