Ma capillaries a Ptfe ndiabwino kwambiri, amapanga gulu lazodziyimira pawokha malinga ndi ntchito yake.Komanso, malinga ndi zosowa zosiyanasiyana, amapangitsa chubu chakuda chakuda, capillary chubu, chubu chachikasu cha capillary, chubu chofiira cha capillary ndi transparent capillary chubu ndi zina zotero, nthawi zambiri zimakhala zabuluu kapena zakuda.
- 1.Ptfe capillary akamaumba ndondomeko
Ptfe capillary chubu ndi chitoliro chapadera chopangidwa ndi kuyanika, kutentha kwapamwamba sintering ndi kumaliza pambuyo kusakaniza ptfe kupezeka utomoni ndi propellant, ndiyeno pansi ena akumeta ubweya mphamvu mkamwa nkhungu ndi cone ngodya.
Ma capillaries a Ptfe ndiabwino kwambiri, amapanga gulu lazodziyimira pawokha malinga ndi ntchito yake.Komanso, malinga ndi zosowa zosiyanasiyana, amapangitsa chubu chakuda chakuda, capillary chubu, chubu chachikasu cha capillary, chubu chofiira cha capillary ndi transparent capillary chubu ndi zina zotero, nthawi zambiri zimakhala zabuluu kapena zakuda.
- 2.Main makhalidwe a ptfe capillary chubu
(1) . Chotsitsa chotsika kwambiri: kugundana kwake nthawi zambiri kumakhala 0.04, ndi chinthu chabwino kwambiri chodzitchinjiriza, ndipo kugundana sikumasintha ndi kutentha.
(2).Kukhazikika kwamphamvu kwamankhwala: kumatha kupirira ma acid onse amphamvu, kuphatikiza aqua regia, hydrofluoric acid, hydrochloric acid, nitric acid, fuming sulfuric acid, organic acid, alkali amphamvu, oxidant amphamvu, kuchepetsa wothandizila ndi zosungunulira zosiyanasiyana organic.Oyenera kwambiri kudyetsedwa kwa mankhwala oyeretsa kwambiri.
(3).Zabwino anti - viscosity, khoma la chubu sikophweka kumamatira ku colloid ndi mankhwala.
(4).Kuchita bwino kwambiri kwamagetsi amagetsi: PTFE ndi zinthu zopanda polar zomwe zimakhala ndi dielectric komanso kukana kwakukulu.Kukhazikika kwake kwa dielectric ndi pafupifupi 2.0, yomwe ndi yaying'ono kwambiri pakati pazinthu zonse zamagetsi zamagetsi.
(5) .Wosinthika komanso wosinthika.
(6) .Good anti - viscosity, chubu khoma sikophweka kumamatira ku colloid ndi mankhwala.
(7) .Part chubu transparency, zosavuta kuona mmene madzimadzi mkati.
3. Kugwiritsa ntchito ptfe capillary chubu
Amagwiritsidwa ntchito mu makampani mankhwala, chlor-alkali makampani, makina, galimoto, magetsi Kutentha chitoliro, zamkati, nthunzi, wothinikizidwa mpweya, exchanger kutentha, ❖ kuyanika, nsalu, mankhwala, mankhwala, makampani njinga, makina khofi ndi mafakitale ena, makamaka ntchito. ngati catheter.
Kuphatikiza apo, mutha kugwiritsanso ntchito fep (PVF ndi sikisi f propylene copolymer) yopangidwa ndi chubu chowonekera, zoyambira zake zimasunga magwiridwe antchito a ptfe, monga: kukana kwapamwamba kwambiri ndi kutentha kochepa, kukhazikika kwamankhwala, kutchinjiriza kwamagetsi, odziwika bwino osamata komanso mphamvu zamakina apamwamba. , kokha pa mlingo mkulu kutentha malire 50 ℃ m'munsi kuposa ptfe.Koma imakhala yosinthika komanso yowonekera kuposa ptfe, zomwe zimapangitsa kuti zikhale zosavuta kuwona zomwe zikuchitika mkati momwe zimatengera zamadzimadzi ndi mpweya.
