Ukutolikwa okushushu kwePVC: Ukusuka kwingeniso yembali, ukhetho (2)

2. Inzuzo kunye nokuqalisa-uthathe iPVC njengomzekelo

Lo mzobo ungezantsi ukhetha ikamva lePVC kunye nentsebenzo yenzuzo ukusuka ku-2016 ukuza kuthi ga ngoku.Phakathi kwabo, inzuzo ikhethe ummeli u-Shandong ngaphandle-kwe-Shandong ngaphandle kwamatye obugcisa kunye neenzuzo ezidibeneyo.Ngenxa yeenzuzo zemithombo yamalahle, ixabiso liphantsi kunelaseMpuma yeChina.Kulula ukumela inzuzo encinci yeshishini.Okwangoku, umthamo we-electron wasekhaya ubalwa malunga ne-80%, i-ethylene amandla oMseki athatha i-20%, kunye nomthamo obanzi wokuvelisa i-chlorine malunga ne-70%.Ekubeni inzuzo ye-chlorine -alkali amashishini adibeneyo iphezulu kakhulu kuneenzuzo zenkampani, i-East China isetyenziselwa ukusebenzisa i-East China kumazwe angaphandle.Inzuzo yeshishini lePVC lamatye ombane lelona nqanaba lisezantsi kwishishini.Ngokomzekelo, inkampani ye-PVC inenzuzo, ngoko imboni inenzuzo xa iyonke.Ukuba i-East China amashishini adibeneyo e-PVC anelahleko yenzuzo, imveliso eqhelekileyo yamashishini inokuchaphazeleka.

Ukujonga ukusuka kwi-2016 ukuya kwi-2023, xa inzuzo yeenkampani zombane ngaphandle kwe-East China yafikelela malunga ne-1,000, yayihamba kunye neyona nto iphezulu kwimarike ehleliweyo, njengoNovemba 2016, Septemba 2017, kunye no-Oktobha 2021. Xa ukuhlanganiswa kwengonyama elahlekileyo. kwakhiwa, ngokusisiseko sikhatshwa ezantsi ebekwe ezantsi, ezifana January 2016, January 2022, kunye noNovemba 2022. Ukuqwalasela imodeli yexesha loshishino, iPVC inesondlo ezimbini kabini ngonyaka entwasahlobo nasekwindla, ngokulandelelana ukusuka ku-Epreli noJuni kunye NgoJulayi-Septemba.Amanqanaba amathathu aphezulu akufuphi nexesha lolondolozo.Ukubonelela ngezigaba kunye nokungalingani kwemfuno kuzise ukunyuka kwamaxabiso.Xa ingeniso yenkampani isanda, ishishini lanyuka ngokukhawuleza.Emva kokuba unikezelo lunyukile kunye nokuzaliswa kwe-downstream ye-database kuncitshisiwe, i-marketing staged.Xa ilahleko zokudityaniswa kwe-chlorine-alkali, ishishini liye lancipha kwisigaba.Nangona kungekho ukuhlolwa okuqhelekileyo kweli nqanaba, kwinqanaba eliphantsi ngexesha elifanayo.Ngamanye amazwi, ukwakhiwa kwenzuzo kukuthatha uhlobo "V".Xa ilahleko, ukwakhiwa "inverted", kwaye inzuzo inxulumene ngokufanelekileyo

Ngenxa yokuba ikhonkco loshishino lwePVC ludityanisiwe ubukhulu becala, ezinye izincedisi kufuneka ziqwalaselwe ngokubanzi xa kuxoxwa ngenzuzo yePVC.Phakathi kwabo, eyona mpembelelo yimveliso ephezulu kunye ne-alkali yeemveliso ezikhaphayo.Okwangoku, amandla emveliso yeNdlela yeCorporal inkulu kakhulu, ngoko ke ixabiso lelitye lombane kunye nePVC lihambelana ngakumbi.Ngokuqhelekileyo, amaxabiso ePVC anyukile ngexabiso lamatye ombane.Uwama-2021 ngunyaka okhethekileyo.Ichaphazeleka kokubini ukusetyenziswa kwamandla.Unikezelo oluphantsi lwamatye ombane luqinile, kwaye ixabiso lamatye ombane linyukile.Kwiinkampani zePVC zombane ezizithweleyo, intshiseko yokuqala iphezulu.Ngeli nqanaba, inzuzo ifunyenwe yi-electronic factory (i-self-reserved stone factory yombane inokuncedisa inzuzo yePVC ngenzuzo yelitye lombane), ngoko kunokubonwa ukuba kunokubonwa ukuba kunokubonwa. ukuba kunokubonwa Nangona ixabiso lePVC liqhubekile ukuphula ixabiso eliphezulu kwi-2021, inzuzo yeenkampani zePVC zeenkampani zePVC zilahlekelwa yimali ngokubanzi.Le nxalenye yeshishini iye yanciphisa imveliso okanye ugcino.Ukongeza Ixesha elifanayo lexesha elifanayo liphantsi.

Amaphepha ePvc angaphandle ePlastiki 

Ixabiso le-alkali ye-alkali nayo inempembelelo enkulu kwindlela yokuziphatha yokwakhiwa kweenkampani ze-PVC.Ngokuqhelekileyo, i-1 toni ye-PVC ihamba kunye ne-0.7-0.8 yeetoni ze-alkalinity.Ingeniso phakathi kwabo ichaphazele omnye nomnye.Ukuwa, inkampani ye-PVC sele iqalile ukuphuhlisa ilahleko, kodwa ngeli xesha umsebenzi weshishini awuzange uchaphazeleke kakhulu.Kuze kube nguJulayi, ixabiso le-alkaline pyrine liwile, libangela ukulahlekelwa kwenzuzo yenkampani edibeneyo ye-chlorine kunye ne-alkali.Imarike yePVC iya kuphinda ibuyele.NgoNovemba ka-2022, i-alkali ye-alkali yancitshiswa kancinci, kwaye inzuzo ebanzi ye-chlorine -alkali yayilahlekelwa yimali.Ngo-Matshi, ixabiso le-alkali eyosiwe liyancipha kakhulu, kwaye ilahleko ye-chlorine -alkali edibeneyo yanda kakhulu.Njengoko ixesha lolondolozo sele liza kungena, kunokuqatshelwa ukuba ixesha lokuqalisa kwalo nyaka lingaphambili kuneminyaka engaphambili.

Ngokubanzi, kumashishini ekhemikhali, ukunyuka kuya kulungelelaniswa ngokweenzuzo zexesha langempela, kwaye ukubonelela ngezigaba kunye nemfuno iya kulungiswa ngokuchaphazela ukubonelela.Ngelo xesha, uhlalutyo lwenzuzo kufuneka ludibaniswe nenkqubo yoshishino.Ukuthatha iPVC njengomzekelo, kufuneka ihlulwe ibe yintlangano kwaye ingadibanisi.Ukongezelela, kuyimfuneko ukudibanisa inzuzo yelitye kunye ne-alkali.Ukongeza, ishishini lokuqokelela umbane lifumene inzuzo ethile njengowona mda uphezulu weshishini, kwaye ilahleko yamashishini adibeneyo akwishishini.Kwangaxeshanye, nayo ifuna ukuqwalaselwa ngokudibanisa nezinye izinto.
