Yonke into ofuna ukuyazi ngeplastiki yePVC

I-Polyvinyl Chloride (i-PVC) yenye yezona zinto zisetyenziswa kakhulu ze-thermoplastic polymers kwihlabathi liphela (emva kweplasitiki ezazisetyenziswa kakhulu ezifana nePet kunye ne-PP). Yimvelo imhlophe kwaye iBrittle (ngaphambi kokuba iplastikhi) ipolisiwe) iplastiki. I-PVC inembali ende kuneyona plastics, iqale iqengqele ngonyaka ka-1872 kwaye iveliswe yinkampani ye-BF ye-BF nge-1920s. Ngokwahlukileyo koko, ezinye iiplanga ezininzi zaqala zantywila kwaye zisebenza kwezorhwebo kuphela nge-1940s kunye ne-50s. Eyona isetyenziswa rhoqo kwishishini lokwakha, ikwasetyenziswa kwimiqondiso, izicelo zononophelo zempilo kunye nefibwe yengubo. I-PVC yafunyanwa ngengozi kabini, kanye ngo-1832 nge-French Henri Revist Regat, emva koko yafunyanwa ngo-1872 ngeJanuge Bauminn.

Ifomu esisiseko kunye nomsebenzi we-polyvinyl chloride (pvc)
I-PVC iveliswa kwiifom ezimbini ngokubanzi: i-rigid okanye i-polymer eqingqiweyo (i-RPVC engasebenziyo okanye i-upvc) kunye neplastiki eguquguqukayo. Kwindlela yayo esisiseko, i-PVC ibonakaliswa yisakhiwo sayo esingqongqo. Ngelixa iinguqulelo ezikrifu zinezinto ezahlukeneyo ezisetyenziswa kumashishini amaninzi, i-PVC engqongqo ikwanokufumana. Amashishini anje njengemibhobho, unyango lwamanzi amdaka kunye nezolimo zinokusebenzisa i-PVC ye-PVC emininzi ngemisebenzi emininzi.


Ukuguquguquka, ukufakwa kweplastiki okanye i-PVC ecacileyo kakhulu kwaye ilungiswe ngakumbi kune-phucc ngenxa yongezwa kweplastiki efana ne-phthalates efana ne-phthalate okanye i-dinp. I-PVC eguquguqukayo isetyenziswa ngokuqhelekileyo yokufakelwa iingcingo zombane, okanye emakhayeni emizini, ezibhedlele, izikolo kunye nezinye iindawo apho imeko iphambili. Ngamanye amaxesha, i-PVC inokuba yinto esebenzayo yerabha. I-rigid pvc ikwasetyenziswa njengokufaka imibhobho kunye nokuhlala kwaye kudla ngokubizwa ngokuba "yiVinyl" e-US. Imibhobho ye-PVC ihlala ibhekiselwa kwiShedyuli yayo. Umahluko ongabonakaliyo phakathi kweeshedyuli zibandakanya ubukhulu becala, ukulinganisa uxinzelelo kunye nombala, phakathi kwezinye.
