Nakhu ukufana nokwehluka phakathi kwe-PVC (Polyvinyl chloride) futhi I-PVDC (Polyvinylidene chloride):

Ukufanayo:

1. Ukwakheka kwamakhemikhali: Kokubili I-PVC futhi i-PVDC ama-polmoplastic polymers aqukethe i-chlorine ekwakhiweni kwawo kwamakhemikhali.
2. I-Barrier Properties: Zombili lezi zinto zibonisa izakhiwo ezinhle zokuvimba ngokumelene nomswakama, umoya-mpilo, namanye amagesi, ibenze balungele ukufakwa kwezicelo.
3. Ukucaca: Kokubili i-PVC ne-PVDC kungenziwa ngezindlela ezisobala, ukuvumela ukubonakala kokuqukethwe okuhlanganisiwe.
4. -Nokwenzeka: Zombili lezi zinto zingacutshungulwa kalula ngamasu ahlukahlukene njengokukhishwa, ukubumba umjovo, kanye nekhalenda.

Ukwehluka:

1. Isakhiwo samakhemikhali: I-PVC i-vinyl polymer eneyunithi ephindaphindwayo ye-CH2 = CHCL, Ngenkathi i-PVDC iyi-vinylidene chloride polymer eneyunithi ephindaphindwayo ye-CH2 = CCL2.
2. Ukusebenza okubanda: I-PVDC inezindawo ezinesithiyo esiphakeme ngokuqhathaniswa ne-PVC. Amafilimu we-PVDC anikezela umswakama omuhle kakhulu nesithiyo segesi, Ukunikeza ukuvikelwa okungcono kwemikhiqizo ebucayi efana nemithi kanye nokudla okubonakalayo.
3. Ukuqina okushisayo: I-PVDC inokuqina okuphezulu okushisayo kune-PVC. Ingamelana namazinga okushisa aphezulu ngaphandle kokuthola ukonakala okubalulekile.
4. Izindleko: I-PVC ngokuvamile ibiza kakhulu ngokuqhathaniswa ne-PVDC, Ukwenza kusetshenziswe kabanzi kuzicelo ezahlukahlukene, kufaka phakathi amapayipi, izintambo, kanye nezinye izinhlelo zokusebenza zokufaka.
5. Umthelela wezemvelo: I-PVC ihlotshaniswe nokukhathazeka kwemvelo ngenxa yokukhishwa kwe-chlorine ne-dioxins ngesikhathi sokukhiqiza nokulahlwa. I-PVDC ibhekwa njengengane enobungane ngokwemvelo njengoba ingakhiphi chlorine noma ama-dioxins ngesikhathi sayo sokuphila.

Kubalulekile ukuqaphela ukuthi i-PVC ne-PVDC inezakhiwo ezihlukile futhi zilungele izinhlelo ezihlukile. I-PVDC ivame ukusetshenziswa kwizicelo zokufaka ezinama-high high lapho kudingeka khona izindawo eziphakeme zokuvimba, Ngenkathi i-PVC ithola izinhlelo zokusebenza ezinhlobonhlobo zezimboni ngenxa yokuguquguquka kwayo kanye nokusebenza kwezindleko.
