Nazi izinto ezifanayo kunye nolwahluko phakathi kwe-PVC (I-polyvinyl chloride) kwaye I-PVDC (I-Polyvinylidene pheloride):

Ukufana:

1. Ukwakhiwa kweekhemikhali: Zombini I-PVC kunye ne-PVDC zii-thermoplastic polymers eziqukethe i-chlorine kwimo yabo yekhemikhali.
2. Iipropati zoMthintelo: Zombini ezi zinto zibonakalisa iipropathi zomqobo ezifanelekileyo ngokuchasene nokufuma, ioksijini, kunye nezinye iigesi, Ukubenzela Ukuze balungele izicelo zokupakisha.
3. Ukungafihli: Zombini i-PVC kunye ne-PVDC zinokwenziwa kwiifom ezibonakalayo, Ukuvumela ukubonakala kwezindilikiselo ezipakisiweyo.
4. Ukudityaniswa: Zombini ezi zixhobo zinokuqhutywa ngokulula ngeendlela ezahlukeneyo ezifana nokuphuma, isitofu sokubumba, kunye nekhalenda.

Umahluko:

1. Isakhiwo sekhemikhali: I-PVC yi-vinyl polymer eneyunithi ephindaphindayo ye-ch2 = chcl, Ngelixa i-pvdc yi-voridene ye-voloride ye-polymer eneyunithi ephindaphindayo ye-ch2 = ccl2.
2. Umsebenzi woRhwebo: I-PVDC inepropathi ebalaseleyo ethelekiswa ne-PVC. Iifilimu ze-PVDC zibonelela ngomswakama ogqwesileyo kunye negesi, Ukunikezela ngokukhuselekileyo kwiimveliso ezibuthathaka ezinjengamayeza kunye nokutya okutshabalalisayo.
3. Uzinzo lwe-thermal: I-PVDC inezinzo eziphezulu ze-thermal iphezulu kune-pvc. Inokumelana nobushushu obuphakathi ngaphandle kokuphazamiseka okukhulu.
4. Iindleko: I-PVC ayibiza kakhulu xa ithelekiswa ne-PVDC, Ukwenza kube lula kwizicelo ezahlukeneyo, kubandakanya imibhobho, iintambo, kunye nezicelo zokupakisha.
5. Impembelelo yokusiNgqongileyo: I-PVC idityaniswe nenkxalabo yendalo ngenxa yokukhutshwa kwe-chlorine kunye neDioxins ngexesha lokuvelisa kunye nokulahlwa. I-PVDC ithathelwa ingqalelo imeko-bume enobuhlobo njengoko ingenzi i-chlorine okanye i-dioxins ngexesha lobomi bayo.

Kubalulekile ukuba uqaphele ukuba i-PVC kunye ne-PVDC inepropathi eyahlukileyo kwaye ilungele izicelo ezahlukeneyo. I-PVDC ihlala isetyenziswa kwizicelo eziphezulu zokupakisha apho kufuneka khona iipropathi eziphambili zomqobo, Ngelixa i-PVC ifumana izicelo kuluhlu olubanzi lwamashishini ngenxa yokungaguqukiyo kunye nokusebenza ngendleko.
