Ptfe capillaries yakanyatsonaka, ichigadzira seti yezvakazvimiririra zvakajairika zvinoenderana nekushandiswa kwayo.Zvakare zvinogona zvichienderana nezvinodiwa zvakasiyana, inoita iyo dema capillary chubhu, chena capillary chubhu, yero capillary chubhu, tsvuku capillary chubhu uye transparent capillary chubhu uye zvichingodaro, kazhinji ibhuruu kana dema reel kurongedza.
- 1.Ptfe capillary molding process
Ptfe capillary chubhu ipombi yakakosha yakagadzirwa nekuomeswa, tembiricha yakakwira sintering uye kupedzisa mushure mekusanganisa ptfe dispersion resin uye propellant, yobva yaiswa kune imwe simba rekugera mumuromo mold nekoni Engle.

- 2.Main maitiro eptfe capillary tube
(1) . Yakanyanya kuderera friction coefficient: yayo friction coefficient inowanzova 0.04 chete, yakanaka kwazvo yekuzvizora zvinhu, uye friction coefficient haichinji netembiricha.
(2).Kugadzikana kwekemikari yepamusoro: inogona kumira kune yose yakasimba acids, kusanganisira aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acid, alkali yakasimba, yakasimba oxidant, inoderedza agent uye zvakasiyana-siyana zvinonyungudutsa.Yakanyatsokodzera zvakanyanya kuchena kwemakemikari kudya.
(3).Yakanaka anti - viscosity, chubhu madziro haisi nyore kuomerera kune colloid nemakemikari.
(4).Yakanakisa magetsi ekudzivirira kuita: PTFE chinhu chakanyanya nonpolar chine yakanaka dielectric zvivakwa uye kuramba kukuru.Dielectric constant yaro inenge 2.0, inova idiki pane zvese zvigadzirwa zvemagetsi ekudzivirira.
(5) .
(6) .Zvakanaka anti - viscosity, tube wall haisi nyore kunamatira kune colloid nemakemikari.
(7) .Part of the tube transparency, nyore kutarisa mukati memvura mamiriro.
3. Kushandiswa kweptfe capillary tube
Inoshandiswa zvakanyanya muindasitiri yemakemikari, chlor-alkali indasitiri, michina, mota, yemagetsi kupisa pombi, pulp, chiutsi, gasi rakamanikidzwa, kupisa kupisa, kupfeka, machira, mishonga, mushonga, indasitiri yebhasikoro, muchina wekofi uye mamwe maindasitiri, anonyanya kushandiswa. se catheter.
Uye zvakare inogona kushandisa fep (PVF uye matanhatu f propylene copolymer) yakagadzirwa nechubhu inoonekera, yakakosha inochengeta mashandiro eptfe, senge: yakanakisa yakakwirira uye yakaderera tembiricha kuramba, kugadzikana kwekemikari, kuvharwa kwemagetsi, yakakurumbira isina kunamatira uye yakakwirira mechani simba. , chete pane yakakwirira tembiricha muganhu 50 ℃ yakaderera pane ptfe.Asi inoshanduka uye yakajeka kupfuura ptfe, zvichiita kuti zvive nyore kuona zviri kuitika mukati sezvo ichitakura zvinwiwa nemagasi.
