Isicelo Ngokubanzi Kwemithi ye-PVC/PVDC

Ukupakishwa Kwemithi I-PVC/PUkubuka konke kwe-VDC:

Amaphilisi emithi e-PVC enziwa ikakhulukazi nge-polyvinyl chloride (I-PVC) i-resin enezinsiza ezithile zokucubungula, ngokusebenzisa i-extrusion, ikhalenda, kanye nezinye izindlela zokucubungula ukukhiqiza into yokupakisha inoveli ehlangabezana nezidingo zokusetshenziswa komuthi. Ihlukanisa ithebhulethi ngayinye, iphilisi, kanye ne-capsule ngokuzimela ukuyenza ibe iyunithi yokupakisha encane kakhulu, okuthuthukisa kakhulu ukunemba nokuphepha kokupakishwa kwemikhiqizo yemithi.

Izakhiwo ze-PVDC zingambozwa ngefilimu ye-PVC ukuze uthole umswakama ophezulu kakhulu kanye nezakhiwo zokuvimbela umoya-mpilo, kuye ngokuthi enamathela isisindo. Amafilimu amabhamuza ahlanganiswe nge-PVDC angamafilimu avimbelayo ajwayelekile futhi adumile asetshenziselwa ukupakishwa kwamabhamuza ekhemisi.. Izingubo ze-PVDC nazo ziyindlela yokonga kakhulu yokwengeza ukumelana kwamanzi nomoya-mpilo kumafilimu e-PVC.

Ukwenyusa Ukuthuthukiswa Kwezinto Zokupakisha Zemithi

Ngemva kokungena ngawo-1990, ukuphepha kwemithi sekuthole ukunakwa okwengeziwe. Ngoba izithako zeminye imithi zingenwa kalula yi-deliquescence kanye ne-oxidation, iphakethe lokuqala le-PVC i-aluminium-plastic ngeke lisakwazi ukuhlangabezana nezimfuneko zokupakisha zale mithi. Ngalesi sikhathi, i-R&Abasebenzi bakwa-D bathuthukise ngempumelelo ishidi lokwelapha le-PVC njengento eyisisekelo futhi bengeza izinto ze-polymer ezinezithiyo eziphezulu (I-PVDC), okuhlanganisa ukuqina kwe-PVC, ukubumba okuhle, kanye namaphunga ahlukahlukene e-PVDC kumhwamuko wamanzi, umoya-mpilo, kanye ne-CO2. Inezindawo ezinhle kakhulu zokuthibela futhi iba yinto eyinhlanganisela yenoveli engahlangabezana nezidingo zokupakishwa kwemithi ewubukhazikhazi kanye ne-oxidized kalula., kanye neminye imithi yamaShayina yokugcina iphunga.

Ukusetshenziswa Okubanzi Kwe-Pvc Yezemithi

Ngesikhathi esifanayo, isasebenzisa uhlobo lokupakisha lwe-PTP aluminium-plastic, kanye nemishini yokupakisha nobuchwepheshe kufana ncamashi nezinto zokupakisha ze-PVC. Lolu chungechunge lwezinto ezihlanganisiwe lungenziwa ngokwezifiso izinto zokupakisha zefekthri ngokuya ngezinga lokuthambekela komswakama kanye ne-oxidation yezidakamizwa., futhi ube uhlobo lokupakisha lwezinga eliphezulu le-PTP. Ngaphezu kwalokho, kukhona izinto zokupakisha ze-PVC/PE esikhundleni samabhodlela engilazi ukugcwalisa imithi ewuketshezi kanye ne-suppository, okuthuthukisa kakhulu ukuphepha kwalolu hlobo lomuthi.

Ukuthuthukiswa Okusheshayo Kokugoqa Kwezokwelapha kwe-Pvdc

Njengempahla ekhethekile, umuthi uya ngokuya udingeka ephaketheni. Izakhiwo ezikhethekile ezibonakalayo ze-pvdc coating zidonse ukunakwa okwengeziwe, futhi ziya ngokuya zisetshenziswa emaphaketheni emithi. Lezi zakhiwo ezikhethekile zomzimba zihlanganisa izakhiwo ezinhle kakhulu zokuvimbela kanye nokuzinza kwamakhemikhali ku-oxygen, umphunga wamanzi, i-carbon dioxide, kanye nama-organic compounds. Njengoba izinto eziningi ze-polymer zicutshungulwa ukuze zifakwe ekhemisi, okuwukuphela kwento eyi-PVDC chloride enezakhiwo ezivimbelayo eziphezulu kumhwamuko wamanzi nomoya-mpilo ngesikhathi esifanayo.. Empeleni, izinto eziningi ze-polymer zinezakhiwo zokuvinjelwa okuphezulu ngokumelene nomhwamuko wamanzi, futhi ungqimba oluncane lwe-PVDC kuzo luzothuthukisa kakhulu lokhu kusebenza. Ngaphezu kwalokho, i-PVDC coating ingaphinda ivimbe umoya-mpilo nezinye izici futhi ilondoloze iphunga.Ifilimu yekhwalithi ephezulu yokupakishwa kwethebhulethi i-pvc/pvdc izothandwa kakhulu.

PVC-PVDC ifilimu Pharmaceutical

I-PVDC plastique nayo inezici zokumelana ne-asidi, ukumelana ne-alkali, ukumelana kwamafutha, ukumelana ne-solvent, kanye nokungazweli emithini, okwenza ifaneleke kakhulu ezinhlotsheni ezahlukene zokupakishwa kwemithi, ikakhulukazi lezo ezijwayele ukudleka, ethambekele ku-oxidation, noma iqukethe izinto ezisebenza ngamakhemikhali futhi idinga ukuvikelwa. Ukupakisha imithi ehogelayo noma evimba ukumuncwa kwephunga elingavamile.
