Ipulasitiki ye-PVC ibhekisela ku-PVC ehlanganisiwe embonini yamakhemikhali.Igama lesiNgisi: i-polyvinyl chloride, isifinyezo sesiNgisi: PVC.Lena incazelo esetshenziswa kakhulu ye-PVC.
Umbala wayo wemvelo uphuzi ngokushintshashintsha futhi uyacwebezela.Ukucaca kungcono kunokwe-polyethylene ne-polypropylene, futhi kubi kakhulu kune-polystyrene.Kuye ngenani lezithasiselo, zingahlukaniswa zibe i-PVC ethambile futhi eqinile.Imikhiqizo ethambile ithambile futhi iqinile, futhi izwakala inamathele.Ukuqina kwemikhiqizo eqinile kuphakeme kunaleyo ye-polyethylene ephansi, kodwa iphansi kune-polypropylene, futhi kuzoba ne-albinism emagodini.Imikhiqizo evamile: amapuleti, amapayipi, amasoli, amathoyizi, iminyango namafasitela, izikhumba zezintambo, izinto zokubhala, njll. Kuwuhlobo lwempahla ye-polymer esebenzisa i-athomu ye-chlorine esikhundleni se-athomu ye-hydrogen ku-polyethylene.
Umgijimi nesango: wonke amasango avamile angasetshenziswa.Uma ucubungula izingxenye ezincane, kungcono ukusebenzisa isango lohlobo lwenaliti noma isango elingaphansi kwamanzi;Ezingxenyeni eziqinile, kungcono ukusebenzisa amasango amise okwefeni.Ububanzi obuncane besango lohlobo lwenaliti noma isango elingaphansi kwamanzi kufanele libe ngu-1mm;Ubukhulu besango elimise okwefeni akufanele libe ngaphansi kuka-1mm.
Ukusetshenziswa okujwayelekile: amapayipi okuhambisa amanzi, amapayipi asendlini, amabhodi odonga endlu, amagobolondo emishini yebhizinisi, ukupakishwa kwemikhiqizo ye-elekthronikhi, izisetshenziswa zezokwelapha, ukupakisha ukudla, njll.
Izakhiwo zamakhemikhali nezomzimba ze-PVC eqinile ye-PVC ingenye yezinto ezisetshenziswa kakhulu zepulasitiki.Izinto ze-PVC ziyi-amorphous material.Izinza, izinto zokuthambisa, ama-axiliary processing agents, ama-pigments, ama-ejenti aqinisayo nezinye izithasiselo kuvame ukungezwa ezintweni ze-PVC ngokusetshenziswa okungokoqobo.
Izinto ze-PVC azikwazi ukuvutha, amandla aphezulu, ukumelana nesimo sezulu kanye nokuzinza okuhle kakhulu kwejometri.I-PVC inokumelana okuqinile nama-oxidants, ama-reductants nama-asidi aqinile.Kodwa-ke, ingagqwala ngama-acid oxidizing agxilile njenge-concentrated sulfuric acid ne-concentrated nitric acid, futhi ayifaneleki izikhathi lapho kuthintana nama-hydrocarbon anephunga elimnandi nama-hydrocarbons ane-chlorinated.
Ukushisa okuncibilika kwe-PVC ngesikhathi sokucubungula kuyipharamitha yenqubo ebaluleke kakhulu.Uma le pharamitha ingalungile, izoholela enkingeni yokubola kwezinto.Izici zokugeleza ze-PVC zimbi impela, futhi uhla lwenqubo yalo luncane kakhulu.Ikakhulukazi, izinto ze-PVC ezinesisindo esikhulu samangqamuzana zinzima kakhulu ukucutshungulwa (le nto ngokuvamile idinga ukwengeza okokugcoba ukuze kuthuthukiswe izici zokugeleza), ngakho-ke izinto ze-PVC ezinesisindo esincane samangqamuzana zivame ukusetshenziswa.Ukuncipha kwe-PVC kuphansi kakhulu, ngokuvamile ku-0.2 ~ 0.6%.
