Izinzuzo ze-PVDC phezu kwe-PVC njengempahla yokupakisha ekhemisi

Ishidi eliqinile le-PVC Yezemithi linendima ebaluleke kakhulu ekufakweni kwemithi, abakhiqizi abaningi bemithi bazokhetha le nto njengephakheji yemithi. Ngokuthuthuka kobuchwepheshe, abantu baye bathuthukisa i-pharma PVC hard sheet, ithuthukele ku-hard sheet ye-PVDC yemithi, izinto zokupakisha izidakamizwa ezithuthukisiwe zinokuthuthuka okuningi kunangaphambili, namuhla ngizokwabelana nawe okwakamuva kunokuqala lokho okugqamisayo.

Ifilimu ebunjiwe ye-PVC ibizwa nge-PVC eqinile ngoba iqukethe cishe izithambisi namapulasitiki. Ingenawo ama-plasticizers, Ibhamuza le-PVC linganikeza ukuqina kwesakhiwo nokuvikelwa ngokomzimba kumafomu omthamo wemithi. I-blister cavity kufanele igcinwe ifinyeleleka ngomphumela we-push-through, futhi i-mesh eyakhiwe ayiwi lapho icindezelwa. Yingakho ukushuba kweshidi le-PVC kuvame ukukhethwa phakathi kuka-200μ no-300μ, kuye ngosayizi womgodi kanye nokuma.

impahla ye-pvc yezokwelapha

Amashidi amaningi e-PVC asetshenziselwa izembozo zamabhamuza okwelapha angama-250µ noma 0.250 mm ubukhulu. Ukudluliswa kwe-oxygen (OTR) imayelana 20 cc/m2/ usuku. Ukuze unqobe inkinga yokusebenza okunganele kwesithiyo sefilimu ye-PVC, I-PVDC ingagcotshwa noma ihlanganiswe ne-PCTFE noma i-COC ukuze kwandiswe ukusebenza kokuvikela. Amafilimu amabhamuza asuselwa ku-Pvc ajwayele ukusetshenziselwa ukupakishwa kwamabhamuza ekhemisi., lapho i-PVC isebenza njengohlaka lwe-thermoforming lwesakhiwo. Izendlalelo ze-PVC zingafakwa umbala ngombala kanye/noma izihlungi ze-UV.

Polyvinylidene chloride (I-PVDC) i-PVC eboshwe. I-PVDC idlala indima ebalulekile ekufakweni kwamabhamuza njenge-laminating noma ukunamathela ku-PVC. I-PVDC inganciphisa ukungena kwegesi namanzi kwe-PVC blister package by 5-10 izikhathi. Ubukhulu befilimu ye-PVC buyi- 8-10 mil; I-PVDC coating is 1-2 mil obukhulu. I-coating isetshenziswa ohlangothini olulodwa, ngokuvamile ibhekene nomkhiqizo kanye ne-capping material.

Nakuba i-PVDC inhle kakhulu ekuvimbeni kokubili umoya-mpilo nomhwamuko wamanzi, amanye ama-polymers amaningi avimbelayo anikeza eyodwa noma enye kuphela. Izakhiwo zokuvimbela igesi azithintwa umswakama ohlobene futhi zingancika ezinhlobonhlobo zokupakisha nezimo zemvelo..

Cishe yonke imikhiqizo ye-PVDC emakethe ingama-copolymers we-vinylidene chloride (I-VDC) namanye ama-comonomers. Inani elihlobene le-VDCS kuma-copolymers linquma izici ezithile ezibalulekile. Inani eliphakeme kakhulu lama-VDC, ngcono ukusebenza komgoqo ngokuvamile, futhi kancane iVDC, ukuguquguquka okwengeziwe ngokuvamile kuyathuthukiswa. Nokho, inombolo kanye nohlobo lwe-comonomer, kanye nezinye izithasiselo nezindlela zokucubungula ezisetshenzisiwe, ingathinta ezinye izakhiwo, njengokuvaleleka, izakhiwo ezingaphezulu, ukucaca, i-gloss coefficient of friction.

PVC-PVDC ifilimu Pharmaceutical

I-ST i-duplex evamile (I-PVDC/PVC) kanye ne-triplex (I-PVDC/PE/PVC) ukucushwa kusetshenziswe i-PVDC coatings. Cishe 67% yemakethe ye-barrier bubble pack isebenzisa lawa mafilimu ane-PVDC ahlanganiswe. Izisindo ezijwayelekile zokumboza ezisetshenzisiwe zihlanganisa 40, 60, 90, kanye ne-120g/m2, futhi ifilimu ye-PVDC ejwayelekile engu-120g/m2 ene-PVC ene-WVTR cishe 0.16 g/m2 kwe 40 oC futhi 75% RH.

Ngokukhula nokuthuthukiswa kobuchwepheshe bokukhiqiza, izidingo zokukhiqiza ze-PVC PVDC zizoqina kakhulu. Njengomkhiqizi wezinto zokupakisha zokwelapha, IHuawei Aluminium nakanjani izomisa inqubo yokukhiqiza futhi inikeze ucwecwe lwe-aluminium olusezingeni elingcono lomuthi.
