I-PVC ihlanganiswa kusuka ku-vinyl chloride nge-polymerization yamahhala.Ngokumiswa kwe-polymerization, i-emulsion polymerization kanye ne-polymerization ngobuningi, i-polymerization yokumiswa iyindlela eyinhloko, ebala cishe ama-80% omkhiqizo we-PVC ophelele.Embonini, inqubo yokukhiqiza ye-PVC ngokuvamile isekelwe endleleni yokuthola i-vinyl chloride monomer ukuze ihlukanise, ingahlukaniswa ngendlela ye-calcium carbide, indlela ye-ethylene kanye nokungeniswa (EDC, VCM) indlela ye-monomer (ngokwesiko ebizwa ngokuthi indlela ye-ethylene kanye nendlela ye-monomer engenisiwe) .Ngokwezindlela ezihlukene zokukhiqiza, i-PVC powder ihlukaniswe yaba: i-resin ye-PVC yendawo yonke, i-PVC resin enezinga eliphezulu le-polymerization, i-crosslinking PVC resin.I-Universal PVC resin yenziwa nge-polymerization ye-vinyl chloride monomer ngaphansi kwesenzo se-initiator;I-PVC resin enezinga eliphakeme le-polymerization ibhekisela ku-resin eyakhiwe ngokungeza i-agent ekhulayo yamaketanga ohlelweni lwe-polymerization ye-vinyl chloride monomer;I-Crosslinked PVC resin iyi-resin eyenziwa nge-polymerized ngokwengeza i-crosslinking agent equkethe i-diene ne-polyene ohlelweni lwe-polymerization lwe-vinyl chloride monomer.

I-polyvinyl chloride resin yokumiswa Imodeli yamanje:

Sg-1: K 77-75 isilinganiso sedigri ye-polymerization

I-Sg-2: K 74-73 isilinganiso sedigri ye-polymerization

I-Sg-3: Inani le-K 72-71 I-average polymerization degree 1350-1250

Sg-4: K inani 70-69 degree degree of polymerization 1250-1150

I-Sg-5: Inani le-K 68-66 Idigri emaphakathi ye-polymerization 1100-1000

I-Sg-6: Inani le-K 65-63 Idigri emaphakathi ye-polymerization 950-850

Sg-7: K inani 62-60 isilinganiso sedigri ye-polymerization 850-750

Sg-8: K inani 59-55 degree degree of polymerization 750-650

Izinhlelo zokusebenza eziyinhloko:

I-PVC resin ingacutshungulwa ibe yimikhiqizo ehlukahlukene yepulasitiki, ngokusho kokusetshenziswa kwayo ingahlukaniswa ngezigaba ezimbili zemikhiqizo ethambile futhi eqinile, ikakhulukazi esetshenziselwa ukukhiqizwa kwezingcezu ezisobala, ukufakwa kwamapayipi, amakhadi egolide, imishini yokumpontshelwa igazi, ethambile futhi eqinile. amapayipi, amapuleti, iminyango kanye nama-Windows, amaphrofayili, amafilimu, izinto zokufaka ugesi kagesi, i-cable sheath, izinto zokumpontshelwa igazi, njll.

1.PVC imikhiqizo ejwayelekile ethambile futhi eqinile - usebenzisa i-extruder ingakhanywa ibe amapayipi athambile naqinile, izintambo, izintambo, njll.;NGOMSHINI wokubumba umjovo kanye nokubunjwa okuhlukahlukene, ungenziwa ube izimbadada zepulasitiki, amasoli, ama-slippers, amathoyizi, izidingo zansuku zonke kanye nezinsiza zemoto nezikagesi.

2 Ipayipi eliqinile le-PVC nephrofayili - uma kuqhathaniswa namanye amapulasitiki, ukumelana nokuguga kwe-PVC kuhle kakhulu, amandla omthelela aphezulu nokuqina, intengo ephansi, ifanele amapayipi okudonsa amanzi kanye namanye amapayipi okwakha, kanye nephrofayili yephrofayili.

Ifilimu ye-PVC engu-3 - I-PVC kanye nezithasiselo ezixutshwe, ukwenza ipulasitiki, ukusetshenziswa komshini wokugoqa okuthathu noma okune kube ugqinsi olucacisiwe lwefilimu esobala noma enemibala, ngale ndlela yokucubungula ifilimu, iba yifilimu ye-calendering.Kungaphinde kusikwe, izikhwama zokupakisha ezishisayo, ama-raincoat, izindwangu zetafula, amakhethini, amathoyizi aphefumulayo nokunye.Ifilimu esobala ebanzi ingasetshenziselwa i-greenhouse, i-plastic greenhouse nefilimu yepulasitiki.Ngemuva kokunwetshwa okuphindwe kabili kwefilimu, indawo yokuncipha kokushisa, ingasetshenziselwa ukupakishwa kokuncipha.

Imikhiqizo engu-4 ye-PVC eboshwe - ene-substrate yesikhumba sokwenziwa i-PVC idideke engutsheni noma ephepheni, bese iba ku-100 degrees Celsius ngaphezu kwepulasitiki.Kungaba futhi ifilimu ye-PVC ne-axiliary calendering, bese icindezelwa kanye ne-substrate.Isikhumba sokwenziwa ngaphandle kwe-substrate siqondiswa ngokuqondile umshini we-calendering ibe ugqinsi oluthile lweshidi elithambile, bese licindezelwa iphethini.Isikhumba sokwenziwa singasetshenziswa ukwenza amapotimende, izikhwama, izembozo zezincwadi, osofa namacushion emoto, nesikhumba saphansi, esisetshenziswa njengempahla yaphansi yokwakha.

Imikhiqizo yegwebu ye-5.PVC - ukuxuba okuthambile kwe-PVC, engeza inani elifanele le-ejenti egwetshiwe ukwenza izinto zeshidi, ukubumba igwebu lepulasitiki legwebu, amaslippers amagwebu, izimbadada, ama-insoles, nezinto zokupakisha ze-shockproof buffer.Futhi INGASEBENZISA i-extruder FOUNDATION eshidini eliqinile le-PVC eligwebu eliphansi kanye nephrofayili, ingathatha indawo yesilingo sokhuni, iwuhlobo olusha lwezinto zokwakha.

Ishidi le-6 le-PVC esobala - I-PVC yengeza isishintshi somthelela nesiqinisi, ngemva kokuxuba, ukwenza ipulasitiki, ukufakwa kwekhalenda futhi kube ishidi elibonisa ngale.Ukusetshenziswa kokwakheka okushisayo kungenziwa kube iziqukathi ezisobala ezinodonga oluncane noma kusetshenziselwe ukupakisha i-vacuum blister, kuyizinto ezinhle kakhulu zokupakisha nezinto zokuhlobisa.

I-7 PVC ipuleti eliqinile nepuleti - i-PVC stabilizer, i-lubricant kanye ne-filler, ngemva kokuxuba, nge-extruder ingakhishwa i-caliber ehlukahlukene yepayipi eqinile, ipayipi emise okukhethekile, i-bellows, isetshenziswe njengepayipi eliphansi, ipayipi lokuphuza, i-wire sleeve noma i-stair handrail.Ukucindezela okushisayo okudlulanayo kweshidi le-calendered kungenza amashidi aqinile anobukhulu obuhlukahlukene.Ipuleti lingasikwa libe yisimo oyifunayo, bese kusetshenziswa ama-electrode e-PVC ane-welding yomoya oshisayo ibe ngamathangi okugcina amakhemikhali amelana nokugqwala, imigudu yomoya neziqukathi.

I-8.PVC enye - iminyango namafasitela enziwe ngezinto eziqinile ezimise okukhethekile.Kwamanye amazwe ubelokhu nge izinkuni iminyango kanye Windows aluminium Windows kanye nezinye iminyango ezivamile kanye Windows market;Ukulingisa izinto zokhuni, izinto zokwakha insimbi yesizukulwane (enyakatho, ngasolwandle);Isitsha esingenalutho.
