I-PVC yenziwe kwi-vinyl chloride nge-polymerization yamahhala.Ngokumiswa kwepolymerization, i-emulsion polymerization kunye ne-polymerization yobuninzi, i-polymerization yokumiswa yeyona ndlela iphambili, ibalwa malunga ne-80% yemveliso ye-PVC iyonke.Kwishishini, inkqubo yokuvelisa i-PVC ngokuqhelekileyo isekelwe kwindlela yokufumana i-vinyl chloride monomer ukwahlula, inokwahlulwa ngendlela ye-calcium carbide, indlela ye-ethylene kunye nokungeniswa (EDC, VCM) indlela ye-monomer (ngokwesiko ibizwa ngokuba yi-ethylene indlela kunye nendlela ye-monomer ephuma kumazwe angaphandle) .Ngokweendlela ezahlukeneyo zokuvelisa, i-PVC powder ihlukaniswe yaba: i-resin ye-PVC yendalo yonke, i-resin ye-PVC enezinga eliphezulu le-polymerization, i-crosslinking PVC resin.I-resin ye-PVC ye-Universal yenziwe nge-polymerization ye-vinyl chloride monomer phantsi kwesenzo somqalisi;I-resin ye-PVC eneqondo eliphezulu le-polymerization ibhekisela kwi-resin eyenziwe ngokudibanisa i-agent ekhulayo yekhonkco kwinkqubo ye-polymerization ye-vinyl chloride monomer;I-resin ye-PVC ye-Crosslinked yi-resin eyenziwa nge-polymerized ngokudibanisa i-agent e-crosslinking equkethe i-diene kunye ne-polyene kwinkqubo ye-polymerization ye-vinyl chloride monomer.

Ukunqunyanyiswa kwe-polyvinyl chloride resin Imodeli yangoku:

Sg-1: K 77-75 iqondo eliphakathi lepolymerization

Sg-2: K 74-73 iqondo eliphakathi lepolymerization

Sg-3: Ixabiso le-K 72-71 Umyinge we-polymerization degree 1350-1250

Sg-4: Ixabiso le-K 70-69 iqondo eliphakathi lepolymerization 1250-1150

Sg-5: Ixabiso le-K 68-66 Iqondo eliphakathi lepolymerization 1100-1000

Sg-6: Ixabiso le-K 65-63 Umyinge weqondo lepolymerization 950-850

Sg-7: Ixabiso le-K 62-60 iqondo eliphakathi lepolymerization 850-750

Sg-8: Ixabiso le-K 59-55 iqondo eliphakathi lepolymerization 750-650

Usetyenziso oluphambili:

I-resin ye-PVC inokucutshungulwa kwiimveliso ezahlukeneyo zeplastiki, ngokokusetyenziswa kwayo inokwahlulwa ibe ngamacandelo amabini eemveliso ezithambileyo nezinzima, ikakhulu ezisetyenziswa ekuveliseni iziqwenga ezicacileyo, izixhobo zokufakelwa kombhobho, amakhadi egolide, izixhobo zotofelo-gazi, ezithambileyo nezilukhuni. imibhobho, iipleyiti, iingcango kunye neeWindows, iiprofayili, iifilimu, izinto zokugquma umbane, i-cable sheath, izinto zotofelo-gazi, njl.

1.PVC jikelele soft and hard products - usebenzisa extruder inokucudiswa kwimibhobho ethambileyo kunye nzima, iintambo, iingcingo, njl.;Ngomatshini wokubumba inaliti kunye nokubumba okwahlukeneyo, unokwenziwa kwiimbadada zeplastiki, iisole, iziliphu, iithoyi, iimfuno zemihla ngemihla kunye nemoto kunye nezixhobo zombane.

2 PVC umbhobho engqongqo kunye neprofayili - ngokunxulumene nezinye iiplastiki, ukuxhathisa ukwaluphala PVC lugqwesileyo, amandla ifuthe eliphezulu kunye nokuqina, ixabiso eliphantsi, ilungele imibhobho yokuhambisa amanzi kunye neminye imibhobho yokwakha, kunye neprofayile.

Ifilimu ye-PVC ye-3 - i-PVC kunye ne-additives edibeneyo, i-plasticizing, ukusetyenziswa kweendlela ezintathu okanye ezine zokuqengqeleka kwi-thickness ecacileyo okanye ifilimu enemibala, kunye nale ndlela yokucubungula ifilimu, ibe yifilimu ye-calendering.Inokunqunyulwa, iingxowa zokupakisha ezishushu, ii-raincoats, amalaphu etafile, iikhethini, iithoyi ezinokuvutheka njalo njalo.Ifilimu ebanzi ecacileyo ingasetyenziselwa i-greenhouse, i-plastic greenhouse kunye nefilimu yeplastiki.Emva kokwelulwa kwe-bidirectional yefilimu, ipropati yokunciphisa ukushisa, ingasetyenziselwa ukupakishwa kwe-shrink.

Iimveliso ezi-4 zePVC eziqatywe - kunye ne-substrate yesikhumba sokwenziwa yi-PVC ibhidekile kwilaphu okanye ephepheni, kwaye emva koko kwi-100 degrees Celsius ngaphezu kweplastiki.Inokuba yiPVC kunye nefilimu encedisayo ye-calendering, kwaye emva koko icinezelwe kunye ne-substrate.Isikhumba sokwenziwa ngaphandle kwe-substrate i-calendering ngokuthe ngqo ngumatshini we-calendering kwi-thickness ethile ye-soft sheet, kwaye emva koko icinezelwe kwipatheni.Isikhumba sokwenziwa sinokusetyenziswa ukwenza iisutikheyisi, iibhegi, izigqubuthelo zeencwadi, iisofa kunye nemiqamelo yemoto, kunye nesikhumba esiphantsi, esisetyenziswa njengesixhobo sokwakha umgangatho.

5.PVC iimveliso amagwebu - ethambileyo PVC ukuxuba, yongeza inani elifanelekileyo arhente ugwebu ukwenza izinto sheet, ukubumba ugwebu iplastiki ugwebu, iziliphu ugwebu, iimbadada, insoles, kunye nezinto zokupakisha buffer shockproof.Kwakhona UNGASEBENZISA extruder ISISEKO ibe ephantsi ugwebu nzima PVC sheet kunye neprofayile, unokutshintsha ulingo iinkuni, luhlobo olutsha lwezixhobo zokwakha.

Iphepha le-6 le-PVC elicacileyo - i-PVC yongeza isilungisi sempembelelo kunye nokuzinzisa, emva kokuxuba, iplastiki, i-calendering kwaye ibe ishidi elicacileyo.Ukusetyenziswa kokubumba okutshisayo kunokwenziwa kwizikhongozeli ezicacileyo ezinodonga oluncinci okanye zisetyenziselwa ukupakisha i-vacuum blister, yinto egqwesileyo yokupakisha kunye nezinto zokuhombisa.

I-7 ye-PVC i-plate enzima kunye ne-plate - i-PVC stabilizer, i-lubricant kunye ne-filler, emva kokuxuba, kunye ne-extruder inokukhutshelwa i-caliber eyahlukeneyo yombhobho onzima, umbhobho owenziwe ngokukhethekileyo, i-bellows, isetyenziswe njenge-downpipe, ipayipi yokusela, i-sleeve yocingo okanye i-stair handrail.Ukucinezela okushushu okungaphezulu kwephepha le-calendered kunokwenza amashiti aqinileyo obunzima obahlukeneyo.Ipleyiti inokusikwa kwimilo enqwenelekayo, kwaye ke ukusetyenziswa kwee-electrode ze-PVC kunye ne-welding yomoya oshushu kwiitanki zokugcina iikhemikhali ezixhathisayo, imibhobho yomoya kunye nezikhongozeli.

I-8.PVC enye - iingcango kunye neeWindows zenziwe ngezinto eziqinileyo ezinokwakheka okukhethekileyo.Kwamanye amazwe iye kunye neengcango zokhuni kunye Windows aluminiyam Windows kunye nezinye iingcango eziqhelekileyo kunye nemarike Windows;Ukuxelisa izinto zokhuni, izinto zokwakha intsimbi yesizukulwana (emantla, elwandle);Isikhongozeli esingenanto.
