Kusiyana pakati pePVC nePVC yezvokurapa

Chii chinonzi PVC? PVC ndiyo chidimbu chepolyvinyl chloride (PolyvinylChloride), iyo isiri-chepfu, hupfu chena husina hwema. PVC ine high chemical kugadzikana, yakanaka plasticity uye yakanakisa magetsi ekudzivirira. Medical PVC (polyvinyl chloride) is thermoplastic resin polymerized nevinyl chloride pasi pechiito chemutangi uye inoshandiswa zvakanyanya mumidziyo yekurapa nemidziyo yekurapa.. Medical PVC ine yakanakisa mechanic simba, biocompatibility, non-toxicity, nyore coloring, kugadzikana kwakanaka kwemakemikari, kudzivirira kutonhora, kurwisa mwaranzi uye kunaka kwekudzivirira kwemagetsi.

Dzidza zvakawanda nezvePVC yezvokurapa?

Chii chinonzi pvc mune zvekurapa?
Mukutaura kwezvokurapa, PVC kazhinji inomirira premature ventricular contraction. Izvi zvinoreva rhythm yemoyo isina kujairika inokonzerwa nemagetsi emagetsi enguva isati yakwana yemaventricles., izvo zvinokanganisa mutinhimira wakajairika wemwoyo. PVC kazhinji haina ngozi, asi kana zvikaitika kakawanda, inogona kuva chiratidzo chechirwere chemwoyo chiri pasi.

PVC yekushandiswa kwekurapa chinhu, izvo zvakasiyana chaizvo kubva pvc zvichireva zvekurapa. Medical PVC inonyanya kushandiswa kugadzira zvinhu zvekurongedza zvemidziyo yekurapa nemidziyo yekurapa. Semuyenzaniso, inogona kushandiswa sechigadzirwa chekugadzira michina yekurapa senge infusion tubes, catheters, uye kubaya tsono. Iyi michina yekurapa inowanzoda kuve neyakanaka biocompatibility uye kugadzikana kwemakemikari kuve nechokwadi chekuchengetedza uye kushanda panguva yekushandiswa.

Zvakanakira zvekurapa zvePVC zvekurapa

Mushonga PVC, ndizvo, mushonga polyvinyl chloride (Polyvinyl chloride) zvinhu, ine zvakakosha zvakanakira mumunda wemishonga packaging.

Zvakanakisa zvemuviri zvimiro zve mushonga PVC

Pfeka kuramba uye kuramba kubvarura: Pharmaceutical PVC zvinhu zvine zvakanaka kupfeka kuramba uye kubvarura kuramba, zvinoreva kuti inogona kudzivirira zvinobudirira kukanganisa kurongedza panguva yekufambisa uye kuchengetedza, nokudaro kuve nechokwadi chekuvimbika kwemushonga.
Compression resistance uye impact resistance: PVC zvinhu zvakare zvine yakanakisa compression kuramba uye kukanganisa kupikisa, iyo inogona kuchengetedza kugadzikana kwechimiro chayo uye chimiro munzvimbo dzakasiyana-siyana, kuwedzera kudzivirira mishonga kubva kumanikidziro ekunze kana kukanganisa.
Kuchinja uye kupeta simba: PVC mapepa ane zvakanaka kuchinjika uye kupeta simba, uye inogona kuramba extrusion uye deformation kubva kunze simba, kuve nechokwadi chekuti mishonga inoramba yakasimba uye isina kusvibiswa panguva yekurongedza uye kushandiswa.

Kugadzikana kwakanaka kwemakemikari

Acid uye alkali kuramba: PVC zvinhu zvine kuramba kwakasimba kune zvakajairika mishonga yemishonga yakadai seasidhi uye alkalis, uye inogona kudzivirira zvinobudirira kuita kwemakemikari pakati pezvinodhaka uye zvekurongedza zvinhu, nokudaro kuve nechokwadi kugadzikana kwemakemikari emishonga.
Oxidation resistance uye corrosion resistance: PVC zvinhu zvakare zvine yakanaka oxidation kuramba uye kusaita ngura, uye inogona kuramba kukukurwa kweoxidants, kuderedza vamiririri uye zvimwe zvinhu, kuwedzera hupenyu hwesherufu yemishonga.

Biocompatibility

PVC zvinhu zvinoshandiswa zvakanyanya muindasitiri yezvokurapa, zvakadai sekugadzira hoses, infusion mabhegi uye zvimwe zvigadzirwa zvekurapa uye zvishandiso zvinosangana nemuviri wemunhu. Izvi zvinokonzerwa nekunaka kwayo biocompatibility, ndizvo, PVC zvinhu hazvizokonzeredze kusawirirana kana zvimwe zvinokanganisa mumuviri wemunhu, nokudaro kuve nechokwadi chekuchengetedzwa uye kuvimbika kwezvinodhaka panguva yekushandiswa.

Zviri nyore kugadzirisa uye mutengo wakaderera

Zviri nyore kugadzirisa uye kuumba: PVC zvinhu zvine purasitiki yakanaka uye processability, uye inogona kuita nyore kuita akasiyana siyana ekugadzirisa uye kuumba mashandiro, zvakadai se extrusion, jekiseni kuumba, etc., nokudaro kuzadzisa zvidikanwi zvakasiyana-siyana zvemunda wekurongedza wemishonga.
Mutengo wakaderera: Kuenzaniswa nezvimwe zvakakwirira-kuita zvekurongedza zvinhu, PVC zvinhu zvine mutengo wakaderera wekugadzira, iyo inogona kuchengetedza mari uye kuvandudza mabhenefiti ehupfumi kumakambani emishonga.

Wide range of applications

Mishonga PVC zvinhu zvinoshandiswa zvakanyanya mumunda wekurongedza kwemishonga nekuda kwezvakanaka zviri pamusoro., senge blister packaging, mishonga yemabhodhoro mavara, zvisimbiso nemabhegi emishonga, etc. Aya mafomu ekurongedza haangogone kuchengetedza mishonga kubva kune yekunze nharaunda, asiwo kunatsiridza kunaka kwekuchengetedza, kutakurwa nekushandiswa kwemishonga.

Mhando dzekushandisa dzePVC dzemishonga mukurongedza zvinodhaka

PVC ipurasitiki yakachipa uye ine michina yakanaka ine simba repamusoro uye kusimba, uye inogona kurwisa zvinobudirira kupinda kweokisijeni uye mhute yemvura. Naizvozvo, PVC inowanzo shandiswa se substrate mukurongedza zvinodhaka, uye iyo yakazara chipingamupinyi zvivakwa inowedzerwa nekusanganiswa nezvimwe zvakakwirira zvipingamupinyi zvinhu (zvakadai sealuminium foil). Naizvozvo, PVC inogona kushandiswa zvakanyanya mukurongedza kwezvigadzirwa zvemishonga.

Mhando dzekushandisa dzePVC dzemishonga (polyvinyl chloride) mune mushonga kurongedza:

Blister packaging

PVC/PVDC composite chimiro chinowanzo shandiswa mu blister kurongedza, kunyanya kumishonga yakasimba yakadai semapiritsi uye capsules. Ichi chiputiriso chinogona kupa kuchengetedzwa kwekupatsanurwa kunoshanda kudzivirira mishonga kubva pakukanganiswa nemhepo uye unyoro. Blister packaging inogona kuve thermoformed kana kutonhora yakadhindwa. PVC inowanzo shandiswa mu thermoforming process ine tembiricha yekudziya inosvika 100 ℃ kusvika 150 ℃..

pharmaceutical blister packaging

Chikamu-dose kurongedza

PVC/PVDC zvinhu zviri nyore kucheka uye zvinogona kuchinjika kugadzirwa kuita yakazvimirira yekurongedza yedosi rimwe uye blister rimwe., izvo zviri nyore kuti varwere vatore pavanenge vachishandisa uye kuderedza marara ezvinodhaka.

Special pharmaceutical packaging:

Zvemishonga zvinonzwa nekunyorova, oksijeni, etc., zvakadai semishonga inorwisa mabhakitiriya, mavitamini, special capsules, etc., PVC/PVDC zvinhu zvinogona kupa zvakanakisa dziviriro.

Infusion mabhegi

PVC inoshandiswawo kugadzira mabhegi ekuisira mishonga. Zvidzidzo zvakaratidza kuti kuwedzera organotin kunogona kuvandudza kujeka uye kugadzirisa fluidity yemabhegi ekurapa PVC infusion.

Zvikamu zvepurasitiki zvekugadzira mishonga

Zvinoenderana nekupatsanurwa kwezvinhu, PVC ndechimwe chezvinhu zvinowanzo shandiswa zvemidziyo yepurasitiki uye zvikamu zvekurongedza kwemishonga, uye inogona kushandiswa kugadzira zvikamu zvepurasitiki zvakaita sevhavha uye mainterface.

Idzi dziri pamusoro ndedzimwe dzemhando huru dzekushandisa dzemishonga PVC mupakiti yemishonga, iyo inoshandisa maitiro ePVC zvinhu, zvakadai sezvipingamupinyi zvinhu, mechanical simba uye kugadzirisa zvinhu, kuve nechokwadi chemhando uye kuchengetedzwa kwezvinodhaka.
