Ukuphela kwempahla eluhlaza: i-calcium carbide ekugcineni kwezinto ezingavuthiwe kunzima ukunikeza ukwesekwa kwezindleko engxenyeni yokuqala ka-2022. Ukunikezwa kwe-calcium carbide kunqunywa ukwakhiwa kwayo kanye nesidingo se-PVC.I-PVC eqinile idinga ukungazinzi, donsela phansi isikhungo se-calcium carbide of gravity.Ethintwe ukucindezela kwenzuzo, izinga lokusebenza le-calcium carbide lalo nyaka uma liqhathaniswa nesikhathi esifanayo ngonyaka odlule lehlile, uhlangothi lokuhlinzeka lunciphile.
Ukuphela kokunikezwayo: Izinga lokusebenza le-PVC ngokuyinhloko licabangela inzuzo yalo.Engxenyeni yokuqala yonyaka, inzuzo yamabhizinisi okukhiqiza i-PVC inhle isikhathi esiningi.Kulo nyaka, izinga lokusebenza le-PVC lisesezingeni eliphezulu ngokomlando.Ukunakekelwa okulandelayo kuncishisiwe, futhi ukuphela kokunikezwa kungase kukhule kancane kancane.
Ukuphela kwesidingo: I-PVC ingeyezimpahla zangemuva komjikelezo wezindlu ezithengiswayo, futhi isidingo sokugcina sixhunywe ngendawo yokuhlala.Izindlu ezithengiswayo zilulama kancane kancane engxenyeni yesibili yonyaka, isidingo se-PVC kulindeleke ukuthi sikhulule indawo elinganiselwe, futhi isidingo sangaphandle singase sibe buthaka, uhlangothi lwesidingo kulindeleke ukuba luthuthuke kodwa lulinganiselwe.Engxenyeni yesibili ka-2022, silinganisela ukuthi ukunikezwa kwe-PVC nesidingo kungase kubonise ukuthuthuka okuncane uma kuqhathaniswa nengxenye yokuqala yonyaka, kodwa ukuthuthukiswa okulethwa ukufunwa kunomkhawulo, i-PVC ingase ibonise ukushaqeka okubuthakathaka, futhi imakethe iyaqhubeka. ukunyusela "okulindelwe okuqinile" kanye "neqiniso elibuthakathaka" ohlangothini lwesidingo.
Okokuqala, ukubuyekezwa kwemakethe
Imakethe ye-PVC ngo-2022 ibuswa okulindelwe okuqinile kanye neqiniso elibuthakathaka ekugcineni kwesidingo.Singahlukanisa imakethe engxenyeni yokuqala yonyaka ibe izigaba eziyisithupha:
(1) NgoJanuwari, ibhange elikhulu lamemezela ukuncishiswa kwezinga lenzalo, ukunciphisa inqubomgomo yemali kusesenayo indawo, futhi imakethe inethemba ngekota yokuqala yamandla okwakha, i-PVC ekulindelweni okuqinile kokushaqeka okunamandla;
(2) NgoFebhuwari, iqiniso elibuthakathaka lalibusa ukuguqulwa kwentengo, isidingo esingaphansi komfula sasisenkathini engekho, ukubuyiswa kokwakhiwa ngemva kweholide kwakuhamba kancane, futhi ingcindezi yokusungula ye-PVC yayiphezulu;
(3) NgoMashi, ukwanda kukawoyela ongahluziwe phesheya kwezilwandle kuholele ekukhuphukeni okuhlangene kwezimpahla eziyinqwaba.Ngokulindelekile kokukhula kwasekhaya okuzinzile, ukukhushulwa kokuthunyelwa kwempahla kwamanye amazwe kanye nokutholwa kabusha kwesidingo sasekhaya kusekele ukuphindaphinda kwentengo yesikhathi esizayo ye-PVC;
(4) Kusukela ngo-April kuya ku-May, ngenxa yomthelela walolu bhubhane, isidingo sasekhaya sasibuthakathaka, ukuthunyelwa kwamanye amazwe kwaba buthaka, futhi intengo yesikhathi esizayo ye-PVC yaqhubeka nokwehla;
(5) Ekuqaleni kukaJuni, ngokuvulwa kweShanghai, uhlangothi lwesidingo kulindeleke ukuthi lululame;
(6) Maphakathi nasekupheleni kukaJuni, isimo sangempela sasiwukuthi isidingo sasekhaya sasingakathuthukisiwe, isidingo sangaphandle sasibuthakathaka, isivinini sokuqoqa sashesha, futhi intengo yesikhathi esizayo ye-PVC yephula izinga futhi yehla.
Okwesibili, izinto zokusetshenziswa: ukusekelwa kwezindleko ze-calcium carbide akwanele
Kunzima ukunikeza ukusekelwa kwezindleko ze-calcium carbide eluhlaza engxenyeni yokuqala ka-2022. Ngokungafani no-2021, ukuphazamiseka kagesi okulinganiselwe kwe-calcium carbide kulo nyaka kuye kwaba buthaka, futhi ukunikezwa kwe-calcium carbide kunqunywa ukwakhiwa kwayo kanye nesidingo se-PVC.Isidingo esiqinile se-PVC asizinzile, donsela phansi isikhungo se-calcium carbide of gravity, okuholela ekulahlekelweni kwamanye amabhizinisi e-calcium carbide, ukwanda kwengcindezi yemikhumbi, ukuba khona kokwehliswa kwentengo ukuze kutholwe ukuziphatha kokuthumela inzuzo.Ethintwe ukucindezela kwenzuzo, izinga lokusebenza le-calcium carbide lalo nyaka uma liqhathaniswa nesikhathi esifanayo ngonyaka odlule lehlile, uhlangothi lokuhlinzeka lunciphile.Njengamanje, ukugcinwa kwedivayisi ye-PVC kukhulu kakhulu, okuholela ekwehleni kwesidingo se-calcium carbide, ingcindezi yenzuzo ye-calcium carbide, ukwehla kwezinga lokusebenza, ngokunciphisa okulandelayo kwedivayisi yokulungisa ye-PVC, isidingo se-calcium carbide kulindeleke ukuba sikhuphuke, inzuzo noma inzuzo. ukulungisa, ukushayela ukunikezwa emuva up.
I-Calcium carbide iyizindleko eziyinhloko zamalahle, ugesi kanye ne-limestone.Iphethini yokuhlinzeka nesidingo se-orchid carbon ixega, akukho ukuphazamiseka okunjengokulawula kabili ukusetshenziswa kwamandla, futhi intengo ishintshashintsha kakhulu ngentengo yamalahle.Ngesikhathi esifanayo sengcindezi yesidingo samabhizinisi angezansi, amabhizinisi amalahle nawo angaphansi kwengcindezi yezindleko ebangelwa ukwehla kancane kwamalahle aluhlaza.
