Uhlalutyo lweendleko zemveliso yePVC
Uhlalutyo lwexabiso lemveliso yePVC,
calcium carbide indlela PVC, ethylene indlela PVC iindleko, ixabiso PVC, abavelisi bePVC, Inkqubo yeVinyl ixabiso lePVC,
Kwiminyaka yakutshanje, ixabiso lePVC liguquguquka kakhulu, kwaye inzuzo yamashishini aneenkqubo ezahlukeneyo nayo yahluke kakhulu.Amashishini axhasa imathiriyeli ekrwada anengeniso, ngelixa amashishini afuna ukuqokelela imathiriyeli ekrwada ejongene nelahleko.
Njengenkqubo yokuvelisa i-PVC idla iitoni eziyi-1.4 ze-calcium carbide ngetoni nganye, utshintshoixabiso PVCIndlela ye-calcium carbide ichatshazelwa kakhulu yi-calcium carbide.Ukusukela ngo-Okthobha ka-2020, ukunyuka kwexabiso le-calcium carbide kukhokelele ekunyukeni kweixabiso PVC.Ngokukodwa emva kwe-2021, phantsi kwemvelaphi yovavanyo lokusetyenziswa kombane, i-calcium carbide, njengemboni yokusetyenziswa kwamandla aphezulu, ithintelwe kakhulu.Iindleko zamashishini ePVC ziye zanyuka ngokunyuka.Ngo-Okthobha ka-2021, iindleko zamanye amashishini eMpuma China zingaphezulu kwe-15000 yuan/ton.Ekupheleni kwe-2022, ixabiso le-calcium carbide ligcinwe kwi-3900-4550 yuan / ton, kunye nexabiso eliphezulu libonakala phakathi koMatshi kunye nexabiso eliphantsi ekupheleni kukaFebruwari no-Aprili.Ke ngoko, iindleko zamashishini ePVC nazo ziyahambelana.
Inkqubo yeVinyl ixabiso lePVCutshintsho luchaphazeleka ngexabiso le-ethylene kunye ne-vinyl chloride.Iindleko zamashishini e-PVC asebenzisa indlela ye-ethylene yonyuka ngokuthe ngcembe ukusuka ekupheleni kuka-Epreli ka-2020, ukususela ekuguqulweni kwe-VCM, isikhundla esiphezulu sibonakala ekupheleni kuka-Oktobha 2021, ngaphezu kwe-14,600 yuan / ton.NgoJanuwari 2022, ukunikezelwa kwe-vinyl chloride kwanda, kwaye iindleko zamashishini okuvelisa i-PVC kwinkqubo ye-ethylene yehla;NgoFebruwari i-vinyl chloride ephantsi kwemfuno iphuculwe, ixabiso lenyuka;Ngo-Matshi, ukunikezelwa kweVCM e-Asia kwakunzima, kwaye ixabiso eliphezulu laliyi-9750 yuan / ton ekupheleni kukaMatshi.
Kwikota yokuqala ye-2022, inqanaba lenzuzo ye-calcium carbide ye-PVC yayilungile, izuza kakhulu kwixabiso eliphantsi le-calcium carbide eluhlaza.NgoJanuwari, inzuzo enkulu yePVC eveliswe yimigodi yangaphandle eShandong yayiyi-33.6 yuan / ton, ukwanda kwe-1182.6 yuan / ton, kunye nokunyuka kwe-6.6 yuan / ton ngonyaka;Ekupheleni kukaFebruwari, inzuzo yePVC eyenziwe kwimveliso yangaphandle ye-electrolytes inyuke nge-165.5 yuan / ton ukuya kwi-199.1 yuan / ton.Ekupheleni kukaMatshi, inzuzo yePVC eveliswe yimveliso yangaphandle yelitye le-electrolytic yayiyi-774 yuan / ton.
Ngokutsho kwe-accounting evela kwi-VCM, kwikota yokuqala ye-2022, inqanaba lenzuzo ye-PVC eyenziwe yindlela ye-ethylene iphantsi kune-calcium carbide method enterprises.NgoJanuwari, iindleko zeabavelisi bePVCyehla, ixabiso lemarike lenyuka kancinci, kwaye inzuzo yamashishini yanda.NgoFebruwari, abachatshazelwa lixabiso eliphezulu vinyl chloride ekrwada, ethylene indlela ukunyuka kweendleko, kwangaxeshanye phakathi kwaye ngasekupheleni February waqala buthathaka ukuthambekela emarikeni, ethylene indlela ixabiso ukukhulula, vinyl indlela imveliso yangaphandle ilahleko ngaphezulu.Ngo-Matshi, njengoko ixabiso le-PVC lenyuka kwaye ixabiso le-VCM lawa, inzuzo yamashishini e-PVC asebenzisa indlela ye-ethylene (PVC) iphuculwe.Kodwa amashishini e-vinyl yasekhaya ye-PVC awona macebo adibeneyo, kwaye indawo yenzuzo inkulu kakhulu kunamashishini e-PVC.
IPVC sisishunqulelo sepolyvinyl chloride.I-resin yinto ehlala isetyenziselwa ukuveliswa kweeplastiki kunye neerubha.I-PVC resin ngumgubo omhlophe osetyenziswa ngokuqhelekileyo ukuvelisa i-thermoplastics.Yimathiriyeli eyenziweyo esetyenziswa kakhulu ehlabathini namhlanje.I-Polyvinyl chloride resin ineempawu ezibalaseleyo ezifana nezixhobo ezininzi eziluhlaza, iteknoloji yokuvelisa ekhulile, ixabiso eliphantsi, kunye noluhlu olubanzi lokusetyenziswa.Kulula ukusetyenzwa kwaye inokucutshungulwa ngokubumba, i-laminating, isitofu sokubumba, i-extrusion, i-calendering, i-blow folding kunye nezinye iindlela.Ngeempawu ezintle zomzimba kunye neekhemikhali, isetyenziswa kakhulu kushishino, ulwakhiwo, ezolimo, ubomi bemihla ngemihla, ukupakishwa, umbane, izinto eziluncedo zikawonke-wonke, kunye namanye amacandelo.Iireyini zePVC zinokumelana neekhemikhali eziphakamileyo.Yomelele kakhulu kwaye iyamelana namanzi kunye ne-abrasion.I-Polyvinyl chloride resin (PVC) inokucutshungulwa kwiimveliso ezahlukeneyo zeplastiki.I-PVC yiplastiki ekhaphukhaphu, engabizi kakhulu, kwaye inobuhlobo nokusingqongileyo.I-Pvc Resin inokusetyenziswa kwimibhobho, iifreyimu zefestile, i-hoses, izikhumba, iintambo zocingo, izihlangu kunye nezinye iinjongo eziqhelekileyo iimveliso ezithambileyo, iiprofayili, izixhobo, iipaneli, i-injection, ukubumba, iimbadada, ityhubhu enzima kunye nezinto zokuhombisa, iibhotile, amaphepha, ikhalenda, inaliti eqinileyo kunye nokubumba, njl njl kunye namanye amacandelo.
Iimbonakalo
I-PVC yenye yezona zinto zisetyenziswa kakhulu kwi-thermoplastic resins.Ingasetyenziselwa ukwenza iimveliso ezinobunzima obuphezulu kunye namandla, njengemibhobho kunye nokufakelwa, iingcango zeprofayili, iifestile kunye namaphepha okupakisha.Isenokwenza iimveliso ezithambileyo, ezinje ngeefilim, amashiti, iingcingo zombane kunye neentambo, iibhodi eziphantsi kunye nesikhumba sokwenziwa, ngokongezwa kweeplasticizers.
