Ama-capillaries e-Ptfe mahle ngokwedlulele, enza isethi yemininingwane evamile ezimele ngokuya ngokusetshenziswa kwayo.Futhi kungase ngokwesidingo esihlukile, kwenza ishubhu elimnyama le-capillary, ishubhu le-capillary elimhlophe, ishubhu le-capillary eliphuzi, ishubhu le-capillary elibomvu kanye neshubhu le-capillary elikhanyayo nokunye, ngokuvamile libe luhlaza okwesibhakabhaka noma elifakwe esondweni elimnyama.
- 1.Ptfe inqubo yokubumba i-capillary
I-Ptfe capillary tube iyipayipi elikhethekile elenziwe ngokomisa, izinga lokushisa eliphezulu lokucwilisa kanye nokuphothula ngemva kokuxuba i-ptfe dispersion resin kanye ne-propellant, bese ingaphansi kwamandla athile okugunda emlonyeni wesikhunta nge-cone Angle.

- 2.Izici eziyinhloko ze-ptfe capillary tube
(1).I-coefficient yokungqubuzana ephansi kakhulu: i-coefficient yayo yokungqubuzana ngokuvamile ingu-0.04 kuphela, iwumsebenzi omuhle kakhulu wokuzithambisa, futhi i-coefficient yokungqubuzana ayishintshi nezinga lokushisa.
(2).Ukuzinza kwamakhemikhali aphezulu: kungamelana nawo wonke ama-acids aqinile, okuhlanganisa i-aqua regia, i-hydrofluoric acid, i-concentrated hydrochloric acid, i-nitric acid, i-fuming sulfuric acid, i-organic acid, i-alkali eqinile, i-oxidant eqinile, i-ejenti yokunciphisa kanye nezinyibilikisi ezihlukahlukene eziphilayo.Ifaneleka kakhulu ukondla kwamakhemikhali okuhlanzeka okuphezulu.
(3).I-anti-viscosity enhle, i-tube wall akulula ukunamathela ku-colloid namakhemikhali.
(4).Ukusebenza okuhle kakhulu kokufakwa kukagesi: I-PTFE iyimpahla engapholi kakhulu enezinto ezinhle ze-dielectric kanye nokumelana okukhulu.I-dielectric constant yayo icishe ibe ngu-2.0, okuyiyona encane kunazo zonke phakathi kwayo yonke imikhiqizo yokufakwa kukagesi.
(5).Ivumelana nezimo futhi iyavumelana nezimo.
(6) .Good anti - viscosity, i-tube wall akulula ukunamathela ku-colloid namakhemikhali.
(7) .Ingxenye ye-tube obala, kulula ukubona isimo sangaphakathi samanzi.
3. Ukusetshenziswa kwe-ptfe capillary tube
Isetshenziswa kabanzi embonini yamakhemikhali, imboni ye-chlor-alkali, imishini, imoto, ipayipi yokufudumeza kagesi, uginindela, umusi, igesi elicindezelwe, isishintshi sokushisa, i-coating, izindwangu, imithi, imithi, imboni yebhayisikili, umshini wekhofi nezinye izimboni, ezisetshenziswa kakhulu. njenge-catheter.
Ngaphezu kwalokho ungasebenzisa futhi i-fep (i-PVF ne-six f propylene copolymer) eyenziwe nge-tube ebonakalayo, igcina ukusebenza kwe-ptfe, okufana: ukumelana nokushisa okuphezulu kakhulu nokuphansi, ukuqina kwamakhemikhali, ukufakwa kukagesi, okuvelele okunganamatheli namandla aphezulu omshini. , kuphela kumkhawulo wokushisa ophezulu ongu-50 ℃ ngaphansi kwe-ptfe.Kodwa ivumelana nezimo futhi isobala kune-ptfe, okwenza kube lula ukubona okwenzeka ngaphakathi njengoba ithutha uketshezi namagesi.
