Qhov sib txawv ntawm PVC thiab kev kho mob PVC

PVC yog dab tsi? PVC yog lub npe luv ntawm polyvinyl chloride (PolyvinylChloride), uas yog non-toxic, tsw tsw dawb hmoov. PVC muaj tshuaj lom neeg ruaj khov, zoo plasticity thiab zoo heev hluav taws xob rwb thaiv tsev. Kev kho mob PVC (polyvinyl chloride) yog ib qho thermoplastic resin polymerized los ntawm vinyl chloride nyob rau hauv qhov kev txiav txim ntawm tus pib thiab yog dav siv nyob rau hauv cov khoom siv kho mob thiab cov khoom siv kho mob.. Kev kho mob PVC muaj lub zog zoo heev, biocompatibility, tsis muaj tshuaj lom, yooj yim xim, zoo tshuaj stability, txias tsis kam, hluav taws xob tsis kam thiab zoo hluav taws xob rwb thaiv tsev.

Kawm paub ntau ntxiv txog kev kho mob PVC?

Dab tsi yog pvc sawv rau hauv kev kho mob?
Hauv kev kho mob, PVC feem ntau yog sawv cev rau lub ventricular contraction ntxov ntxov. Qhov no yog hais txog lub plawv dhia tsis zoo uas tshwm sim los ntawm kev ua kom hluav taws xob ntxov ntxov ntawm lub ventricles, uas cuam tshuam qhov kev sib dhos ntawm lub plawv. PVC feem ntau tsis muaj teeb meem, tab sis yog tias nws tshwm sim ntau zaus, tej zaum nws yuav yog ib qho cim ntawm kab mob plawv.

PVC rau kev kho mob yog cov khoom siv, uas txawv heev ntawm pvc lub ntsiab lus kho mob. Kev kho mob PVC feem ntau yog siv los ua cov khoom ntim khoom siv kho mob thiab khoom siv kho mob. Piv txwv li, nws tuaj yeem siv los ua cov khoom tsim khoom siv kho mob xws li cov raj infusion, catheters, thiab puncture koob. Cov khoom siv kho mob no feem ntau yuav tsum muaj biocompatibility zoo thiab tshuaj lom neeg ruaj ntseg kom muaj kev nyab xeeb thiab ua tau zoo thaum siv.

Kev kho mob zoo ntawm cov tshuaj PVC

Cov tshuaj PVC, uas yog, tshuaj polyvinyl chloride (Polyvinyl chloride) khoom, muaj qhov zoo tseem ceeb hauv kev ntim tshuaj.

Lub cev zoo heev ntawm tshuaj PVC

Hnav tsis kam thiab tsim kua muag: Pharmaceutical PVC khoom muaj qhov hnav tsis kam thiab tsim kua muag, uas txhais tau hais tias nws tuaj yeem tiv thaiv kev puas tsuaj rau lub ntim thaum thauj thiab khaws cia, yog li ua kom muaj kev ncaj ncees ntawm cov tshuaj.
Compression kuj thiab cuam tshuam tsis kam: Cov khoom siv PVC kuj muaj qhov zoo heev compression tsis kam thiab cuam tshuam tsis kam, uas tuaj yeem tswj xyuas qhov ruaj khov ntawm nws cov duab thiab cov qauv hauv ntau qhov chaw, ntxiv tiv thaiv cov tshuaj los ntawm sab nraud siab los yog cuam tshuam.
Flexibility thiab folding lub zog: Cov ntawv PVC muaj qhov yooj yooj yim thiab folding lub zog, thiab tuaj yeem tiv thaiv extrusion thiab deformation los ntawm sab nraud quab yuam, kom ntseeg tau tias cov tshuaj nyob twj ywm thiab tsis muaj kuab paug thaum ntim thiab siv.

Zoo tshuaj stability

Acid thiab alkali tsis kam: Cov khoom siv PVC muaj zog tiv thaiv cov khoom xyaw tshuaj xws li acids thiab alkalis, thiab tuaj yeem tiv thaiv cov tshuaj tiv thaiv zoo ntawm cov tshuaj thiab cov khoom ntim, li no kom ntseeg tau cov tshuaj stability ntawm cov tshuaj.
Oxidation kuj thiab corrosion kuj: Cov khoom siv PVC kuj muaj oxidation zoo thiab corrosion kuj, thiab tuaj yeem tiv taus qhov yaig ntawm oxidants, txo tus neeg sawv cev thiab lwm yam tshuaj, txuas ntxiv rau lub txee lub neej ntawm cov tshuaj.

Biocompatibility

Cov ntaub ntawv PVC yog dav siv hauv kev kho mob kev lag luam, xws li npaj hoses, infusion hnab thiab lwm yam khoom siv kho mob thiab khoom siv uas tuaj yeem tiv nrog tib neeg lub cev. Qhov no yog vim nws zoo biocompatibility, uas yog, PVC cov ntaub ntawv yuav tsis ua rau muaj kev tsis haum tshuaj lossis lwm yam teebmeem hauv tib neeg lub cev, yog li ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov tshuaj thaum siv.

Yooj yim rau txheej txheem thiab tus nqi qis

Yooj yim rau txheej txheem thiab pwm: Cov khoom siv PVC muaj cov yas zoo thiab kev ua haujlwm zoo, thiab tuaj yeem yooj yim nqa tawm ntau yam kev ua thiab molding kev ua haujlwm, xws li extrusion, txhaj tshuaj molding, lwm., yog li ua tau raws li cov kev xav tau sib txawv ntawm cov chaw ntim tshuaj.
Tus nqi qis: Piv nrog rau lwm cov ntaub ntawv ntim khoom ua tau zoo, Cov khoom siv PVC muaj cov nqi tsim khoom qis dua, uas tuaj yeem txuag cov nqi thiab txhim kho cov txiaj ntsig kev lag luam rau cov tuam txhab tshuaj.

Ntau yam kev siv

Cov khoom siv tshuaj kho mob PVC tau siv dav hauv kev ntim tshuaj vim yog cov txiaj ntsig saum toj no, xws li blister ntim, tshuaj lub raj mis labels, seals thiab hnab tshuaj, lwm. Cov ntaub ntawv ntim no tsis tuaj yeem tiv thaiv cov tshuaj zoo los ntawm ib puag ncig sab nraud, tab sis kuj txhim kho qhov yooj yim ntawm kev khaws cia, kev thauj mus los thiab kev siv tshuaj.

Daim ntawv thov hom tshuaj PVC hauv kev ntim tshuaj

PVC yog ib tug pheej yig thiab mechanically zoo yas nrog siab zog thiab rigidity, thiab tuaj yeem tiv thaiv kev nkag mus ntawm oxygen thiab dej vapor. Yog li ntawd, PVC feem ntau yog siv los ua substrate hauv ntim tshuaj, thiab tag nrho cov khoom thaiv kev tiv thaiv yog txhim kho los ntawm kev sib xyaw nrog lwm cov khoom thaiv siab (xws li aluminium foil). Yog li ntawd, PVC tuaj yeem siv dav hauv kev ntim cov khoom lag luam.

Daim ntawv thov hom tshuaj PVC (polyvinyl chloride) hauv kev ntim tshuaj:

Kev ntim khoom ntim

PVC / PVDC composite qauv feem ntau yog siv rau hauv ntim ntim, tshwj xeeb tshaj yog rau cov khoom siv tshuaj xws li ntsiav tshuaj thiab tshuaj ntsiav. Cov ntim no tuaj yeem muab kev tiv thaiv kev sib cais kom zoo los tiv thaiv cov tshuaj los ntawm kev cuam tshuam los ntawm huab cua thiab noo noo. Blister ntim tuaj yeem yog thermoformed lossis txias stamped. PVC feem ntau yog siv rau hauv cov txheej txheem thermoforming nrog cua sov ntawm li 100 ℃ txog 150 ℃.

tshuaj blister ntim

Kev ntim khoom ntim

PVC / PVDC cov ntaub ntawv yog ib qho yooj yim los txiav thiab tuaj yeem hloov tau yooj yim tsim rau hauv kev ntim khoom ntawm ib koob thiab ib lub hlwv., uas yooj yim rau cov neeg mob noj thaum siv thiab txo cov tshuaj pov tseg.

Kev ntim tshuaj tshwj xeeb:

Rau cov kws kho mob uas nkag siab txog cov dej noo, oxygen, lwm., xws li tshuaj tua kab mob, vitamins, tshwj xeeb capsules, lwm., PVC / PVDC cov ntaub ntawv tuaj yeem muab kev tiv thaiv zoo heev.

Infusion hnab

PVC kuj tseem siv los ua cov hnab ntim tshuaj kho mob. Cov kev tshawb fawb pom tau hais tias ntxiv organotin tuaj yeem txhim kho qhov pom tseeb thiab ua kom muaj dej ntawm cov tshuaj PVC infusion hnab..

Yas Cheebtsam rau kev ntim tshuaj

Raws li kev faib khoom, PVC yog ib qho ntawm cov khoom siv feem ntau siv rau cov ntim yas thiab cov khoom siv rau kev ntim tshuaj, thiab tuaj yeem siv los ua cov khoom siv yas xws li npog thiab cov interfaces.

Cov saum toj no yog qee yam ntawm cov ntawv thov tseem ceeb ntawm cov tshuaj PVC hauv kev ntim tshuaj, uas siv cov yam ntxwv ntawm cov ntaub ntawv PVC, xws li barrier zog, mechanical zog thiab kev ua haujlwm, los xyuas kom meej qhov zoo thiab kev nyab xeeb ntawm cov tshuaj.
