Isici 1: I-PVC eqinile ingenye yezinto ezisetshenziswa kakhulu zepulasitiki.Impahla ye-PVC yinto engeyona i-crystalline.

Isici sesi-2: Iziqinisi, izinto zokuthambisa, ama-ejenti asizayo okucubungula, izimibalabala, ama-anti-impact agents nezinye izithasiselo kuvame ukungezwa ezintweni ze-PVC ekusetshenzisweni kwangempela.

Isici sesi-3: Impahla ye-PVC inokungashi, amandla aphezulu, ukumelana nesimo sezulu kanye nokuzinza okuhle kakhulu kwejometri.

Isici sesi-4: I-PVC inokumelana okuqinile nama-oxidants, ama-ejenti anciphisayo nama-asidi aqinile.Kodwa-ke, ingagqwala ngama-acid oxidizing agxilile njenge-concentrated sulfuric acid kanye ne-concentrate nitric acid futhi ayifanele ukuthintana nama-hydrocarbon anephunga elimnandi nama-hydrocarbon ane-chlorinated.

Isici sesi-5: Izinga lokushisa elincibilikayo le-PVC ngesikhathi sokucubungula liyipharamitha yenqubo ebaluleke kakhulu.Uma le pharamitha ingalungile, izodala inkinga yokubola kwezinto.

Isici sesi-6: Izici zokugeleza ze-PVC zimbi impela, futhi uhla lwenqubo yalo luncane kakhulu.Ikakhulukazi i-PVC enesisindo samangqamuzana aphezulu kunzima kakhulu ukuyicubungula (lolu hlobo lwezinto ngokuvamile ludinga ukungeza okokugcoba ukuze kuthuthukiswe izici zokugeleza), ngakho-ke impahla ye-PVC enesisindo esincane samangqamuzana ivame ukusetshenziswa.

Isici sesi-7: Izinga lokushwabana kwe-PVC liphansi kakhulu, ngokuvamile li-0.2~0.6%.

I-Polyvinyl chloride, efushanisiwe njenge-PVC (i-Polyvinyl chloride) ngesiNgisi, iyi-vinyl chloride monomer (VCM) kuma-peroxides, ama-azo compounds nezinye iziqalisi;noma ngaphansi kwesenzo sokukhanya nokushisa ngokuya nge-free radical polymerization reaction mechanism Ama-Polymers akhiwe yi-polymerization.I-vinyl chloride homopolymer kanye ne-vinyl chloride copolymer zihlangene zibizwa ngokuthi i-vinyl chloride resin.

I-PVC iyimpushana emhlophe enesakhiwo se-amorphous.Izinga le-branching lincane, ukuminyana kwesihlobo cishe ku-1.4, izinga lokushisa lokushintsha kwengilazi lingu-77 ~ 90 ℃, futhi liqala ukubola cishe ku-170 ℃.Ukuzinza ekukhanyeni nasekushiseni kubi, ngaphezu kuka-100 ℃ noma ngemva kwesikhathi eside.Ukuchayeka elangeni kuzobola ukuze kukhiqizwe i-hydrogen chloride, ezoqhubeka yenze ukubola ngokuzenzakalela, kubangele ukushintsha kombala, futhi izakhiwo ezingokomzimba nezomshini nazo zizokwehla ngokushesha.Ekusetshenzisweni okungokoqobo, ama-stabilizers kufanele afakwe ukuze kuthuthukiswe ukuzinza ekushiseni nasekukhanyeni.

Isisindo samangqamuzana e-PVC ekhiqizwa ngokwezimboni ngokuvamile siphakathi kuka-50,000 kuya ku-110,000, nge-polydispersity enkulu, futhi isisindo samangqamuzana sikhuphuka ngokuncipha kwezinga lokushisa le-polymerization;alinayo indawo yokuncibilika engaguquki, iqala ukuthamba ku-80-85℃, futhi iba yi-viscoelastic ku-130℃, 160℃ 180℃ iqale ukuguquka ibe isimo se-viscous fluid;inezinto ezinhle zomshini, amandla okubamba cishe ama-60MPa, amandla omthelela ngu-5～10kJ/m2, futhi inezici ezinhle kakhulu ze-dielectric.

I-PVC ibikade ingumkhiqizo omkhulu kunawo wonke emhlabeni wamapulasitiki ahloselwe ukujwayelekile, futhi isetshenziswa kabanzi.Isetshenziswa kabanzi ezintweni zokwakha, imikhiqizo yezimboni, izidingo zansuku zonke, isikhumba saphansi, amathayela aphansi, isikhumba sokwenziwa, amapayipi, izintambo nezintambo, amafilimu okupakisha, amabhodlela, izinto ezigwebu, izinto zokuvala, imicu, njll.

Imboni yethu isebenzisa okuhleisikhuntaizinto zokwakha, ezifana ne-718, 718H, njll., izinto zokubumba ezinhle, impilo ende, kanye nemikhiqizo esetshenziswa ezintweni ezahlukahlukene zepulasitiki zingakhiqiza imikhiqizo yepulasitiki ephezulu.
