Li-capillaries tsa Ptfe li ntle haholo, li etsa sete ea litlhaloso tse akaretsang tse ikemetseng ho latela ts'ebeliso ea eona.Hape e ka 'na ea e-ba ho ea ka tlhokahalo e fapaneng, e etsa hore tube e ntšo ea capillary, e tšoeu ea capillary, e mosehla ea capillary, e khubelu ea capillary le transparent capillary tube joalo-joalo, hangata e putsoa kapa e ntšo e pakiloeng.
- 1.Ptfe mokhoa oa ho bopa capillary
Ptfe capillary tube ke phala e khethehileng e entsoeng ka ho omisa, mocheso o phahameng oa sintering le ho qetela ka mor'a ho kopanya ptfe dispersion resin le propellant, ebe e tlas'a matla a itseng a ho kuta molomong oa hlobo ka Khoune Angle.
Li-capillaries tsa Ptfe li ntle haholo, li etsa sete ea litlhaloso tse akaretsang tse ikemetseng ho latela ts'ebeliso ea eona.Hape e ka 'na ea e-ba ho ea ka tlhokahalo e fapaneng, e etsa hore tube e ntšo ea capillary, e tšoeu ea capillary, e mosehla ea capillary, e khubelu ea capillary le transparent capillary tube joalo-joalo, hangata e putsoa kapa e ntšo e pakiloeng.
- 2.Main litšobotsi tsa ptfe capillary tube
(1) . E tlaase haholo ea khohlano: coefficient ea eona ea likhohlano hangata ke 0.04 feela, ke sesebelisoa se setle haholo sa ho itlotsa, 'me coefficient ea khohlano ha e fetohe le mocheso.
(2).Botsitso bo phahameng ba lik'hemik'hale: e ka mamella li-acids tsohle tse matla, ho kenyelletsa le aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acid, alkali e matla, oxidant e matla, e fokotsang moemeli le li-solvents tse fapaneng tsa tlhaho.E loketse haholo bakeng sa ho fepa lik'hemik'hale tse phahameng.
(3).Anti-viscosity e ntle, lebota la tube ha le bonolo ho khomarela colloid le lik'hemik'hale.
(4).Ts'ebetso e ntle haholo ea ho kenya motlakase: PTFE ke thepa e se nang polar e nang le thepa e ntle ea dielectric le khanyetso e kholo.Dielectric constant ea eona e ka ba 2.0, e leng eona e nyane ka ho fetisisa har'a lihlahisoa tsohle tsa motlakase.
(5).E tenyetseha ebile e tenyetseha.
(6) . Good anti - viscosity, tube lerako ha ho bonolo ho khomarela colloid le lik'hemik'hale.
(7) .Karolo ea ho pepeseha ha tube, ho bonolo ho boloka boemo ba mokelikeli o ka hare.
3. Tšebeliso ea ptfe capillary tube
E sebelisoa haholo indastering ea lik'hemik'hale, indasteri ea chlor-alkali, mechine, koloi, phala ea motlakase e futhumatsang, makhasi, mouoane, khase e hatelitsoeng, mocheso oa mocheso, ho roala, masela, meriana, meriana, indasteri ea libaesekele, mochini oa kofi le liindasteri tse ling, tse sebelisoang haholo-holo. joalo ka catheter.
Ho phaella moo, e ka boela ea sebelisa fep (PVF le tse tšeletseng f propylene copolymer) e entsoeng ka tube e bonaletsang, motheo oa eona o boloka ts'ebetso ea ptfe, joalo ka: ho hanyetsa mocheso o phahameng le o tlaase, ho tsitsisa lik'hemik'hale, ho kenya motlakase, ho hlahella ha ho khomarela le matla a phahameng a mochine. , feela ka mocheso phahameng moeli 50 ℃ tlase ho feta ptfe.Empa e bonolo ebile e pepenene ho feta ptfe, e etsa hore ho be bonolo ho bona se etsahalang ka hare ha e tsamaisa maro le likhase.
