Hezvino zvakafanana uye mutsauko pakati pePVC (Polyvinyl chloride) uye PVDC (Polyvinylidene chloride):

Zvakafanana:

1. Chemical Composition: Zvose PVC uye PVDC ndeye Thermoplastic polymers ine chlorine mune yavo yemakemikari chimiro.
2. Barrier Properties: Zvese zvigadzirwa zvinoratidzira zvakanaka zvipfukudzo zvinotsungirira zvinopesana nekunyorova, oksijeni, uye mamwe magasi, Kuvaita kuti vakwanise kurongedza kurongedza mafomu.
3. Transparency: Ose PVC uye PVDC inogona kugadzirwa mumhando dzinoongororwa, Kubvumira kuoneka kweiyo yakarongedzwa zviri mukati.
4. Kufunga: Zvinhu zvese zviri zviviri zvinogona kugadzirwa nyore nyore kuburikidza nehunyanzvi dzakasiyana siyana senge kubuda, jekiseni kuumba, uye Calingreat.

Misiyano:

1. Chemical chimiro: PVC iri vinyl polymer ine kudzokorora unit ye ​​ch2 = CHCL, Ipo PVDC iri vinylidene chloride chloride polymer ine inodzokorora unit ye ​​ch2 = CLL2.
2. Kuita Kwekuimba: PVDC ine yepamusoro inotambisa zvivakwa zvinoenzaniswa nePVC. Mafaira ePVDC anopa zvakanakisa zvinyoro-nyoro uye gasi chipinganidzo, Kupa dziviriro dziri nani kune zvigadzirwa zvine tsvina senge mishonga uye chikafu chinoparara.
3. Kugadzikana kweTermal: PVDC ine yakakwira yekudzora kugadzikana kupfuura PVC. Inogona kutsungirira tembiricha yepamusoro pasina kudzvanywa kwakakosha.
4. Mutengo: PVC inowanzo kuve yakadhura inofananidzwa nePVDC, Kuita kuti iwanikwe zvakanyanya mukushandiswa kwakasiyana siyana, kusanganisira mapaipi, tambo, uye kumwe kurongedza macomputer.
5. Kukanganisa kwezvakatipoteredza: PVC yave yakabatana neyakatipoteredza inokonzerwa nekuburitswa kwe chlorine uye dioxins panguva yekugadzira uye kuraswa. PVDC inoonekwa seyakawedzera kushamwaridzana sezvo isingasunungure chlorine kana dioxins panguva yayo yehupenyu.

Izvo zvakakosha kuti uzive kuti PVC uye PVDC ine zvakasiyana zvivakwa uye zvakakodzera kuti zvibodzwa zvakasiyana. PVDC inowanzoshandiswa mune yakakwira-barrier pacaling application ipo Superor Barrier Zvivakwa Zvinodiwa, nepo PVC ichiwana mafomu mune yakasarudzika manhamba ezvigadzirwa nekuda kweshanduro yayo uye mutengo-kushanda.
