Izinto zokusetshenziswa zokulungiselela ipayipi le-PVC eliqinile elinezindonga ezimbili ezinothayela
Izinto zokusetshenziswa zokulungiselela ipayipi le-PVC eliqinile elinodonga olumbili,
Izinto ezingavuthiwe zokukhiqiza ipayipi le-PVC elinodonga olubili lukathayela,
I-Polyvinyl Chloride (PVC) iyi-resin eqondile ye-thermoplastic ekhiqizwa yi-polymerization ye-vinyl chloride monomer.Ngenxa yomehluko wezinto ezingavuthiwe, kunezindlela ezimbili zokwenza inqubo ye-vinyl chloride monomer calcium carbide kanye nenqubo ye-petroleum.I-Sinopec PVC yamukela inqubo yokumiswa okubili, ngokulandelana kwayo kusukela ku-Japan Shin-Etsu Chemical Company kanye ne-American Oxy Vinyls Company.Umkhiqizo unokumelana nokugqwala kwamakhemikhali okuhle, indawo enhle kakhulu yokufaka ugesi kanye nokuzinza kwamakhemikhali.Ngokuqukethwe okuphezulu kwe-chlorine, izinto ezisetshenziswayo zinokubambezeleka okuhle komlilo kanye nezakhiwo zokuzicisha.I-PVC kulula ukuyicubungula nge-extrusion, ukubumba umjovo, i-calendering, ukubunjwa kokushaywa, ukucindezela, ukubunjwa kwe-cast kanye nokubumba okushisayo, njll.
Isicelo
I-PVC ingenye yezinhlaka ze-thermoplastic ezisetshenziswa kakhulu.Ingasetshenziselwa ukwenza imikhiqizo enobulukhuni obuphezulu namandla, njengamapayipi nokufakwa, iminyango enephrofayili, amafasitela namashidi okupakisha.
Ingakwazi futhi ukwenza imikhiqizo ethambile, efana namafilimu, amashidi, izintambo zikagesi nezintambo, amabhodi aphansi kanye nesikhumba sokwenziwa, ngokufaka ama-plasticizers.

Impahla eluhlaza esetshenziselwa ukwenza ipayipi likathayela we-PVC ilungiswa kusuka
I-PVC (100 pts.wt.),
i-trisalt (6.4-6.8 pts.wt.),
i-lead stearate (0.42-0.47 pts.wt.),
i-barium stearate (1.4-1.7 pts.wt.),
i-stearic acid (0.42-0.47 pts.wt.),
i-microcrystal parafini (0.36-0.41 pts.wt.),
i-polyvinyl wax (0.58-0.62 pts.wt.),
I-ACR (401) (1.9-2.1 pts.wt.),
i-polyethylene ekhonjiwe (5.8-6.3 pts.wt.),
i-superfine calcium carbonate (9-11 pts.wt.)
I-AC 316 (0.28-0.33 pts.wt.).
Izinzuzo zayo ukusebenza kokugcoba okuphezulu, amandla omthelela, ukuqina kwendandatho kanye ne-Vicat softening temp, imvelo enhle yokudiliza, kanye nepulasitiki enhle kakhulu enezinga eliphansi.
