Isicelo ngokubanzi se-PVC / pvdc

Ukupakishwa kwamayeza I-PVC /PUshwankathelo lweVDC:

Iitafile ze-PVC ze-PVC zenziwa ikakhulu nge-polyvinyl chloride (I-PVC) i-resin ngoncedo oluthile lokulungisa, Ngokuphumelela, i-calender, kunye nezinye iindlela zokulungisa ukuvelisa izinto zePasika zeNoves ezihlangabezana neemfuno zokusetyenziswa kwamayeza. Yahlula ithebhulethi nganye, ipilisi, kunye ne-cappele ngokuzimeleyo ukwenza iyunithi encinci yomncinci, ephucula kakhulu ukuchaneka nokhuseleko lweemveliso zephakeji.

Iipropathi ze-PVDC zinokudityaniswa kwifilimu ye-PVC yokufuma kakhulu ukufuma kakhulu umswakama kunye ne-oxygen engaqhelekanga, Kuxhomekeke kubunzima bokuthinta. Iifilimu ze-PVDC ezihlanganisiweyo ze-PVDC zezona filimu zixhaphakileyo nezidumileyo zeRists ezisetyenziselwa ukupakisha amayeza. Iingubo ze-PVDC zezona ndlela zezoqoqosho zokongeza ukunyangwa kwamanzi kunye neoksijini kwiifilimu ze-PVC.

Ukuphuculwa okwandayo kwezixhobo zokupakisha zamayeza

Emva kokungena kwi-1990s, Ukhuseleko lwamayeza lufumene ingqalelo ngakumbi. Kuba izithako zamanye amayeza zichaphazeleka kukungahambi kakuhle kunye ne-oxidation, Ukupakisha iplastiki ye-PVC ye-Alumnum ye-PVC ayinakukwazi ukuhlangabezana neemfuno zokupakisha zala mayeza. Ngeli xesha, r&Abasebenzi baphuhliswa ngempumelelo i-PVC yephepha le-PVC njengezinto ezisisiseko kwaye yongeza ezinye izinto eziphezulu zePolymer (I-PVDC), edibene nengqongqo ye-PVC, ubumba obuhle, kunye ne-pvdc eyahlukeneyo kwi-vapor yamanzi, ioksijini, kunye ne-CO2. Inezixhobo ezigqwesileyo kwaye iba yinto yokuhlanganisa inovel enokuhlangabezana neemfuno zokupakisha kunye namayeza akhutshelweyo ngokulula, kunye namanye amayeza aseTshayina ukugcina ivumba elimnandi.

I-PVC / PVDC yePhepha yeMicimbi ye-Blister

Ukusetyenziswa ngokubanzi kwePVC yePVC

Ngaxeshanye, Isasebenzisa uhlobo lwepakethi yePitho yePETP, kwaye izixhobo zokupakisha kunye netekhnoloji ziyafana ngokuchanekileyo kwezinto zokupakisha zePVC. Olu ngceselo lwezixhobo zokudibanisa zinokwenziwa izixhobo zokupakisha zomzi-mveliso ngokwenqanaba lokungalindelekanga ekufumeni kunye ne-oxidation yamachiza, kwaye ube luhlobo lwepakethi ephezulu yePTP ephezulu. Ukwengeza, Kukho izixhobo ze-PVC / ze-PE zepakisi endaweni yeebhotile zeglasi ukuze zigcwalise ulwelo kunye namayeza e-sceretory, ephucula kakhulu ukhuseleko lolu hlobo lwamayeza.

Uphuhliso olukhawulezileyo lwe-PVDC ye-PVDC ye-PVDC

Njengomntu okhethekileyo, amayeza ayanda kwiphakeji. Iipropathi ezikhethekileyo zomzimba ze-PVDC Ceating zitsalele umnxeba ngakumbi kwaye ziqwalaselwe ngakumbi, kwaye ziya zisetyenziswa kupakisha amayeza. Ezi ndawo zikhethekileyo zomzimba zibandakanya iipropathi ezigqwesileyo kunye nezinzwa zekhemikhali kwioksijini, umphunga wamanzi, umoya omdaka, kunye nemilinganiselo ye-organic. Ngokuthengiswa kwezixhobo zePolymer zenziwa kwiphakeji yamayeza, Into kuphela eyi-pvdc chloride inezinto eziphezulu zomqobo kwi-vapor ephezulu kunye neoksijini ngexesha elinye. Inyaniso, Uninzi lwezixhobo zePolymer zinezithintelo eziphezulu zomqobo ngokuchasene ne-vapor yamanzi, kunye nomaleko omncinci we-PVDC kubo uya kuphucula kakhulu le nkqubo. Ukwengeza, Ukudibana kwe-PVDC kungayithintela ioksijini kunye nezinye izinto kunye nokugcina i-Calgraper ye-Callipt Plates yeThebhu ye-PVC / PVDC ithandwa kakhulu.

Ifilimu ye-PVC-pvdc i-PARMACEOCATIC

I-PVDC Plastique ikwanazo neepropathi ze-acid, I-Alkali ukunganyangeki, Ukunganyangeki kwegrisi, Ukunganyangeki kwe-Solvent, kunye nokuxhathisa iziyobisi, Ukwenza kube lufaneleke ngakumbi kwiindidi ezahlukeneyo zokupakishwa kwamachiza, ngakumbi abo bathambekele kwi-deliquescent, thambeka kwi-oxidation, okanye iqulethe izinto ezisebenzayo zekhemikhali kwaye ifuna ukhuseleko. Ukupakisha amayeza aphunga okanye athintele ukufunxa iphunga.
