Syringe mafiritachishandiso chakakosha mubharasha, chinoshandiswa kucheka zvinwiwa kuti ubvise zvimedu uye microorganisms. Pakati pezvisikwa zvakasiyana-siyana izvo zvinogona kushandiswa kune syringe filters, polytetrafluoroothery (PTFE) uye Polyvinylidene Fluoride (PVDF) isarudzo mbiri dzakakurumbira, imwe neimwe ine zvivakwa zvakasiyana uye zvinoshandiswa. Kunzwisisa misiyano pakati pezvinhu zviviri zviviri kwakakosha pakusarudza faira iyo inokodzera zvido zvako zvekutarisana.
Mibvunzo inowanzo bvunzwa nezve syringe mafirita, ita shuwa yekuongorora ichi chinyorwa chinodzidzisa:Iyo musoro we "syringe filter" 50 mibvunzo inowanzo bvunzwa
Zvinhu Zvivakwa
PTFE (PolytetraFluoroetheryle)
Chemical composition: PTFE ine chete kabhoni uye fluorine maatomu, achiumba chimiro chakagadzikana.
Hydrophos: Ptfe is hydrophobic muchimiro, zvinoreva kuti inodzora mvura uye haigone kushandiswa zvinobudirira mumhinduro dzemvura. Ichi chivakwa chinoita kuti ive yakanaka yekuputika inoshatisa solgressive uye yakasimba acids.
Kupisisa kupisa kwakasimba: PTFE kunogona kurambidza kupisa kubva -60 ° ° C kusvika ku150 ° C, ichiita kuti zviite zvakaringana zvekushandisa zvakasiyana zvinoda kugadzikana zvine mwero.
Kemical Resistance: Inoratidzira kupokana kwakanyanya kumakemikari mazhinji, kusanganisira acidha nehasha uye zvigadziko. PTFE haina kutakura zvinobviswa muzvikamu zvemitambo, ichingoita kuchena kwakanyanya kwemuenzaniso wakasununguka.
PVDF (Polyvinylidene Fluoride)
Cemical Composition: PVDF inoumbwa nekudzokorora Vinylidene Fluoride zvikamu, ichigadzira iyo polymer iyo iri mbiri inoshanduka uye yakasimba.
Hydrophilicity: Kusiyana nePTFE, PVDF ndeye hydrophilic uye inogona kupindirana nemvura. Izvi zvinobvumidza kuti ishandiswe zvinobudirira pamwe nezvose zviri zviviri uye organic sol sol.
High tembiricha yekudziya: PVDF ine huwandu hwakawandisa hwekutuka, kukwanisa kumira tembiricha kubva -200 ° C kusvika 260 ° C. Izvi zvinoita kuti zviite kuti zviite zvekushandisa izvo zvinoda kukwidziridzwa kwakanyanya kwekugadzikana.
Kemical Resistance: Ipo PVDF iri kuramba kumakemikari mazhinji, zvinowanzoitika pane ptfe. Izvo zvinonyanya kushanda pakucheka zvinyoro nyoro soles, asi zvinogona kunge zvisina kukodzera kune acids yakasimba kana zvigadziko.
Filtration application
Zvakakodzera zvikumbiro zvePTFE mafirita
Corrosives solhts:Ptsfe mafiritaIva nemakemikari akanyanya kurwisa uye akakodzera kuti gadzirise soles inokanganisa, kusanganisira yakaiswa acids uye zvigadziko.
Misoro yegesi: Iyo hydrophobic zvisikwa zvinobvumira mafirita ePTFE kuti ishandiswe musi Filtration Failication application uko mvura inofanirwa kusiiwa.
Chromatography: Mafirita mafirita anowanzo shandiswa mu chromatography yekuchengetedza chiridzwa kubva mukusvibiswa pasina kuburitsa zvinowanikwa.
Zvigadzirwa zvakakodzera zvePVDF mafirita
Biological samples:PVDF Mafiritandidzo dzinodzikira madziro anosunga membranes yakakodzera kuti zvibodzwa zvinosanganisira mapuroteni uye masampulogical samples.
HPLC FILTRATION: Ivo vanoshandiswa zvakanyanya neyekucheka mbozhanhare uye samples mune yakakwira performance like chromatography (HPLC) nekuti inoenderana nemvura uye organic sol sol.
General Laboratory Shandisa: PVDF Mafirita anogona kushandiswa mune dzakasiyana-siyana nharaunda dzinoda mikana yemakemikari yemakemikari isina protein inosunga.
Maitiro ekuita
Chiyero chinoyerera
Mafirita ePTFE: Ivo kazhinji vane yakaderera inoyerera mari inodarika PVDF nekuda kweiyo yavo dense chimiro uye hydrophobic chimiro.
PVDF Mafirita: Ivo vanowanzo kupa yakakwira mwero inoyerera nekuti ivo vanonyoroveswa nemvura mhinduro, iyo inomhanya iyo ficha yefaira4.
Zvinobuda
Mafirita ePTFE: Ivo vanozivikanwa nekuda kwekudziya kwavo kwakaderera; Ivo havamanikidze vanonamira mumitambo yemitambo, iyo inokoshesesa yekuongorora pfungwa.
PVDF Mafirita: Ivo vanoratidzawo zvakaderera, asi zvinogona kunge zvakakwirira zvishoma pane ptfe nekuda kweiyo hydrophilic mamiriro. Nekudaro, ivo vachiri kucherechedzwa vakakodzera kune vazhinji vekuongorora.
Mutengo unofungidzirwa
PVDF Mafirita anowanzoita zvishoma kudhura kupfuura mapepa ePTFA nekuda kwemisiyano mumutengo wezvekutakura zvinhu uye maitiro ekugadzira. Iyi yekubhadhara-inoshanda inoita pvdf sarudzo yakakurumbira mune dzakawanda bhajeti-yakamanikidzwa nzvimbo dzekutandarira.
Iwe unoda here kuziva huwandu hwakazara nezve maitiro ekusarudza iyo chaiyo syringe firita, ndapota tarisa chinyorwa ichi: Maitiro ekusarudza iyo yakakwana syringe firita yekugadzirira kwako kwemuenzaniso?

Mhedziso
Mukupfupikisa, zvese ptfe uye pvdf syringe mafirita ane akasiyana zvivakwa zvinovaita kuti vakwanise kuve vakasiyana zvikumbiro:
Mapficha ePTFE:
Zvakanakira zvekushora sols uye gasi filtration.
Hydrophobic; isina kukodzera mhinduro dzemvura.
Yakanakisa makemikari kurwisa neakaderera kubvisa.
PVDF Mafirita:
Yakanakira kune biological samples uye HPLC application.
Hydrophilic; inoenderana nekwavo uye organic sol sol.
Yakakwira inoyerera mitengo, asi zvishoma zvishoma nezvishoma pane ptfe.
