Umahluko phakathi kwePVC kunye nePVC yonyango

Yintoni iPVC? I-PVC sisishunqulelo se-polyvinyl chloride (PolyvinylChloride), engeyiyo ityhefu, umgubo omhlophe ongenavumba. I-PVC inozinzo oluphezulu lweekhemikhali, iplastiki elungileyo kunye nokufakelwa kombane okugqwesileyo. I-PVC yonyango (polyvinyl chloride) I-resin ye-thermoplastic eyenziwe nge-vinyl chloride phantsi kwesenzo somqalisi kwaye isetyenziswa ngokubanzi kwizixhobo zonyango kunye nezixhobo zonyango.. I-PVC yezoNyango inamandla omatshini abalaseleyo, biocompatibility, non-toxicity, umbala lula, uzinzo oluhle lweekhemikhali, ukumelana nokubanda, ukumelana nemitha kunye nokugquma kakuhle kombane.

Funda ngakumbi malunga nePVC yezonyango?

Imele ntoni i-pvc ngokwemiqathango yezonyango?
Kwimiqathango yezonyango, I-PVC idla ngokumela ukufinyela kwe-ventricular kwangaphambi kwexesha. Oku kubhekisa kwisingqi sentliziyo esingaqhelekanga esibangelwa kukusebenza kombane kwangaphambi kwexesha kwiiventricles., ephazamisa isingqisho esiqhelekileyo sentliziyo. IPVC ayinabungozi, kodwa ukuba iyenzeka rhoqo, isenokuba luphawu lwesifo sentliziyo esisezantsi.

I-PVC yokusetyenziswa kwezonyango yinto, eyahluke kakhulu kwi-pvc ethetha ngonyango. I-PVC yonyango isetyenziselwa ukwenza izinto zokupakisha izixhobo zonyango kunye nezixhobo zonyango. Umzekelo, ingasetyenziswa njengento yokuvelisa izixhobo zonyango ezifana ne-infusion tubes, iicatheters, kunye neenaliti zokugqobhoza. Ezi zixhobo zonyango ngokuqhelekileyo kufuneka zibe ne-biocompatibility efanelekileyo kunye nokuzinza kweekhemikhali ukuqinisekisa ukhuseleko kunye nokusebenza ngexesha lokusetyenziswa.

Izibonelelo zonyango zePVC zamayeza

PVC yonyango, yiyo i, i-polyvinyl chloride yonyango (Polyvinyl chloride) impahla, ineenzuzo ezibalulekileyo kwindawo yokupakisha amayeza.

Iimpawu zomzimba ezigqwesileyo ze PVC yonyango

Nxiba ukuxhathisa kunye nokumelana nokukrazula: Imathiriyeli yePVC yamayeza inokumelana nokunxiba kakuhle kunye nokumelana nokukrazula, oku kuthetha ukuba inokuthintela ngokufanelekileyo umonakalo wokupakisha ngexesha lokuthutha kunye nokugcinwa, ngaloo ndlela iqinisekisa ukuthembeka kweyeza.
Ukunyanzeliswa koxinzelelo kunye nokuxhatshazwa kwempembelelo: Izixhobo zePVC zikwanoxhathiso olubalaseleyo loxinzelelo kunye nokumelana nempembelelo, enokugcina uzinzo lobume bayo kunye nesakhiwo kwiindawo ezahlukeneyo, ukukhusela ngakumbi amayeza kuxinzelelo lwangaphandle okanye impembelelo.
Ukuguquguquka kunye namandla okugoba: PVC sheets babe bhetyebhetye elungileyo kunye namandla esongwayo, kwaye inokuxhathisa i-extrusion kunye ne-deformation evela kumandla angaphandle, ukuqinisekisa ukuba amachiza ahlala ekhuselekile kwaye engangcoliseki ngexesha lokupakishwa nokusetyenziswa.

Uzinzo oluhle lweekhemikhali

Ukumelana ne-Acid kunye ne-alkali: Izinto ze-PVC zinokuchasana okunamandla kwizithako eziqhelekileyo zonyango ezifana ne-acids kunye ne-alkali, kwaye inokuthintela ngokufanelekileyo ukusabela kweekhemikhali phakathi kweziyobisi kunye nezinto zokupakisha, ngokwenza njalo kuqinisekisa uzinzo lwekhemikhali yamachiza.
Ukumelana ne-oxidation kunye nokumelana nokubola: Imathiriyeli ye-PVC ikwanayo nokumelana ne-oxidation elungileyo kunye nokumelana nomhlwa, kwaye inokumelana nokukhukuliseka kwee-oxidants, ukunciphisa ii-agent kunye nezinye izinto, ukwandisa ngakumbi ubomi beshelufu yamayeza.

Biocompatibility

Izinto zePVC zisetyenziswa kakhulu kushishino lwezonyango, ezifana nokulungisa imibhobho, iingxowa zokufakela kunye nezinye izixhobo zonyango kunye nezixhobo ezidibana nomzimba womntu. Oku kungenxa ye-biocompatibility yayo elungileyo, yiyo i, Izinto ze-PVC aziyi kubangela ukusabela komzimba okanye ezinye iziphumo ezibi emzimbeni womntu, ngaloo ndlela iqinisekisa ukhuseleko kunye nokuthembeka kwamachiza ngexesha lokusetyenziswa.

Kulula ukusetyenzwa kunye neendleko eziphantsi

Kulula ukusetyenzwa kunye nokubumba: Izinto zePVC zineplastiki elungileyo kunye nokuqhubekeka, kwaye inokwenza lula imisebenzi eyahlukeneyo yokucwangcisa kunye nokubumba, njenge-extrusion, isitofu sokubumba, njl., ngoko ke kuhlangatyezwana neemfuno ezahlukeneyo zommandla wokupakisha amayeza.
Ixabiso eliphantsi: Xa kuthelekiswa nezinye izinto zokupakisha ezisebenza kakhulu, Izinto zePVC zineendleko eziphantsi zokuvelisa, enokonga iindleko kunye nokuphucula inzuzo yezoqoqosho kwiinkampani zamachiza.

Uluhlu olubanzi lwezicelo

Izinto zePVC zamayeza zisetyenziswa kakhulu kwindawo yokupakisha amayeza ngenxa yeenzuzo ezingentla., njengokupakishwa kwamadyungudyungu, iilebhile zebhotile yeyeza, amatywina kunye neengxowa zamayeza, njl. Ezi fom zokupakisha azikwazi kuphela ukukhusela amayeza ngokufanelekileyo kwimeko yangaphandle, kodwa kwakhona ukuphucula lula ukugcinwa, uthutho nokusetyenziswa kwamayeza.

Iindidi zokusetyenziswa kwePVC yamayeza ekupakishweni kweziyobisi

I-PVC yiplastiki enexabiso eliphantsi kwaye ilungile ngoomatshini kwaye inamandla aphezulu kunye nokuqina, kwaye inokuxhathisa ngokufanelekileyo ukungena kweoksijini kunye nomphunga wamanzi. Ngoko ke, I-PVC isoloko isetyenziswa njenge-substrate yokupakishwa kweziyobisi, kunye neempawu zothintelo ngokubanzi ziphuculwe ngokudibanisa nezinye izinto ezithintelweyo eziphezulu (njengefoyile yealuminiyam). Ngoko ke, I-PVC ingasetyenziswa ngokubanzi kwipakethe yeemveliso zamayeza.

Iintlobo zesicelo sePVC yamayeza (polyvinyl chloride) kwipakethe yamayeza:

Ukupakishwa kwamadyungudyungu

Isakhiwo esihlanganisiweyo sePVC/PVDC sisoloko sisetyenziswa kwi-blister package, ngakumbi kumachiza aqinileyo afana neepilisi kunye neepilisi. Le phakheji inokubonelela ngokhuseleko lokwahlula olusebenzayo ukukhusela amachiza ukuba angachatshazelwa ngumoya kunye nokufuma. Ukupakishwa kweBlister kunokuba ne-thermoformed okanye isitampu esibandayo. I-PVC idla ngokusetyenziswa kwinkqubo ye-thermoforming kunye nobushushu bobushushu obumalunga ne-100 ℃ ukuya kwi-150 ℃..

ukupakishwa kwamadyungudyungu amayeza

Ukupakishwa kwesahlulo sedosi

Iimathiriyeli zePVC/PVDC kulula ukuzisika kwaye zinokulungiswa ngokuguquguqukayo zibe kwipakethe ezimeleyo yedosi enye kunye neblister enye., ekulungeleyo ukuba izigulane zithathe xa zisebenzisa kwaye zinciphisa inkunkuma yamachiza.

Ukupakishwa okukhethekileyo kwamayeza:

Kumayeza anokuchukumiseka kukufuma, ioksijini, njl., njengamayeza okubulala iintsholongwane, iivithamini, ii-capsules ezikhethekileyo, njl., Izinto zePVC/PVDC zinokubonelela ngokhuseleko olubalaseleyo.

Iingxowa zokufakela

I-PVC ikwasetyenziselwa ukwenza iingxowa zokufakelwa kwezonyango. Uphononongo lubonise ukuba ukongeza i-organotin kunokuphucula ukungafihli kunye nokusetyenzwa kwe-fluidity yeengxowa zonyango ze-PVC.

Amacandelo eplastiki yokupakisha amayeza

Ngokokuhlelwa kwezinto, I-PVC yenye yezinto ezisetyenziswa ngokuqhelekileyo kwizikhongozeli zeplastiki kunye namacandelo okupakisha amayeza, kwaye ingasetyenziselwa ukwenza amacandelo eplastiki afana namagquma kunye nojongano.

Ezi zingentla zezinye zezona ntlobo zezicelo eziphambili ze-PVC zamachiza kwi-package yamayeza, ezisebenzisa iimpawu zemathiriyeli yePVC, njengeempawu zomqobo, amandla oomatshini kunye neempawu zokucubungula, ukuqinisekisa umgangatho kunye nokhuseleko lwamachiza.
