1. Yini ishidi le-PVC eliqinile?
Igama eligcwele le-PVC eliqinile shidi liyi-polyvinyl chloride shidi eqinile. Ishidi le-PVC eliqinile yi-polymer impahla eyenziwe nge-vinyl chloride njengezinto ezibonakalayo eziluhlaza, ezinabakhuthalo, ama-lubrances kanye nabasizi bengeziwe. Ine-antioxidant ephezulu ye-antioxidant, ukumelana ne-acid enamandla, amandla aphezulu, ukuqina okuhle nokungavunyelwanga, futhi kungamelana nokugqwayiza okubangelwa ukuguquguquka kwesimo sezulu. Amashidi ajwayelekile we-PVC aqinile afaka amashidi asobala we-PVC, amashidi amhlophe e-PVC, amashidi omnyama we-PVC, amashidi we-PVC anemibala, amashidi empunga ama-PVC, njll.
2. Yini inzuzo yeshidi le-PVC eliqinile?
Amashidi e-PVC aqinile anezinzuzo eziningi ezinjengokumelana nokugqwala, ukungavuli, ukufakwa kanye nokumelana nokukhala kwe-oxidation. Ngaphezu kwalokho, zingaphindiselwa futhi zibe nezindleko eziphansi zokukhiqiza. Ngenxa yokwahlukana kwabo okusetshenziswayo kanye namanani ashibhile, bebehlala bethola ingxenye yemakethe yephepha lepulasitiki. Njengamanje, ukuthuthukiswa kwezwe lethu kanye nobuchwepheshe bama-PVC amashidi afinyelele ezingeni eliphakeme lomhlaba wonke.
3. Yini ukusetshenziswa kwephepha le-PVC?
Amashidi e-PVC aguquguqukayo kakhulu, futhi kunezinhlobo ezahlukene zamashidi e-PVC, anjengamashidi e-Transparent PVC, amashidi e-PVC ahamba ngezinyawo, njll. Amashidi e-PVC asetshenziswa kabanzi futhi asetshenziselwa ikakhulukazi ukukhiqiza: Isembozo esibophayo se-PVC, amakhadi we-PVC, amafilimu anzima we-PVC, amashidi anzima we-PVC, njll.
4. Yini ukungathandeki kweshidi le-PVC?
Ishidi le-PVC libuye libe yipulasitiki evame ukusetshenziswa. Kuyi-resin eyakhiwe ngePolyvinyl Chloride Resin, i-Plistic, ne-antioxidant. Akukubi ngokwako. Kepha izinto ezisizayo ezisizayo ezinjengamapulasitiki nama-antioxidants anobuthi. Amapulasitiki ePlastics ye-Daily PVC yePVC ikakhulukazi asebenzisa i-Dibutyl Terephthalate kanye ne-dioctyl perthalate. Lawa makhemikhali anobuthi. I-antioxidant lead stearate esetshenziswe ku-PVC nayo inobuthi. Amashidi e-PVC aqukethe ama-antioxidants aholayo azohola ukuhola uma ehlangana nama-solvents anjenge-ethanol ne-ether. Amashidi aqukethe ama-PVC aqukethe amaphakheji wokudla. Lapho behlangana namakhephu inhlama ethosiwe, amakhekhe athosiwe, izinhlanzi ezithosiwe, imikhiqizo ephekiwe yenyama, amakhekhe kanye nama-snacks, njll. Ngakho-ke, izikhwama zepulasitiki zePVC azikwazi ukusetshenziselwa ukubamba ukudla, ikakhulukazi ukudla okunamafutha. Ngaphezu kwalokho, imikhiqizo yepulasitiki ye-polyvinyl chloride izovusa kancane kancane i-hydrogen chloride gesi emazingeni okushisa aphezulu, njenge-50 ° C, okuyingozi emzimbeni womuntu.
