Ptfe capillaries yog qhov zoo heev, tsim cov txheej txheem ntawm kev ywj pheej dav dav raws li nws siv.Kuj tseem tuaj yeem ua raws li qhov xav tau sib txawv, ua rau lub raj dub capillary, lub raj dawb capillary, lub raj daj capillary, lub raj capillary liab thiab pob tshab capillary raj thiab lwm yam, feem ntau yog xiav lossis dub reel packing.
- 1.Ptfe capillary molding txheej txheem
Ptfe capillary raj yog cov yeeb nkab tshwj xeeb ua los ntawm kev ziab, kub kub sintering thiab ua tiav tom qab sib xyaw ptfe dispersion resin thiab propellant, thiab tom qab ntawd raug rau qee qhov shearing quab yuam hauv lub qhov ncauj pwm nrog lub khob hliav qab.
Ptfe capillaries yog qhov zoo heev, tsim cov txheej txheem ntawm kev ywj pheej dav dav raws li nws siv.Kuj tseem tuaj yeem ua raws li qhov xav tau sib txawv, ua rau lub raj dub capillary, lub raj dawb capillary, lub raj daj capillary, lub raj capillary liab thiab pob tshab capillary raj thiab lwm yam, feem ntau yog xiav lossis dub reel packing.
- 2.Main yam ntxwv ntawm ptfe capillary raj
(1) Tsis tshua muaj kev sib txhuam coefficient: nws cov kev sib txhuam coefficient feem ntau tsuas yog 0.04, yog ib qho khoom siv zoo heev rau tus kheej lubricating, thiab kev sib txhuam coefficient tsis hloov nrog qhov kub thiab txias.
(2).Kev ruaj ntseg tshuaj lom neeg: nws tuaj yeem tiv taus txhua yam muaj zog acids, suav nrog aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acid, muaj zog alkali, muaj zog oxidant, txo tus neeg sawv cev thiab ntau yam organic solvents.Heev haum rau siab purity tshuaj noj.
(3).Kev tiv thaiv zoo - viscosity, raj phab ntsa tsis yooj yim rau kev ua raws li cov tshuaj colloid thiab tshuaj.
(4).Kev ua tau zoo ntawm hluav taws xob rwb thaiv tsev: PTFE yog cov khoom siv tsis zoo nrog cov khoom siv hluav taws xob zoo thiab ua haujlwm zoo.Nws qhov dielectric tas li yog li 2.0, uas yog qhov tsawg tshaj plaws ntawm tag nrho cov khoom hluav taws xob rwb thaiv tsev.
(5) Yooj yim thiab yoog raws.
(6) Kev tiv thaiv zoo - viscosity, raj phab ntsa tsis yooj yim rau kev ua raws li cov tshuaj colloid thiab tshuaj.
(7) Ib feem ntawm lub raj pob tshab, yooj yim los soj ntsuam cov dej hauv cov xwm txheej.
3. Kev siv ptfe capillary raj
Nws yog dav siv nyob rau hauv kev lag luam tshuaj, chlor-alkali kev lag luam, machinery, tsheb, hluav taws xob cua sov yeeb nkab, pulp, chav, compressed gas, tshav kub exchanger, txheej, textile, tshuaj, tshuaj, tsheb kauj vab kev lag luam, kas fes tshuab thiab lwm yam lag luam, mas siv. raws li catheter.
Tsis tas li ntawd tseem tuaj yeem siv fep (PVF thiab rau 6 f propylene copolymer) ua los ntawm cov raj pob tshab, nws qhov yooj yim khaws cov kev ua tau zoo ntawm ptfe, xws li: zoo heev kub thiab kub tsis kam, tshuaj stability, hluav taws xob rwb thaiv tsev, tseem ceeb tsis nplaum thiab siab mechanical zog. , tsuas yog nyob rau lub siab kub txwv 50 ℃ qis dua ptfe.Tab sis nws yooj yim dua thiab pob tshab dua ptfe, ua rau nws yooj yim dua kom pom dab tsi tshwm sim sab hauv thaum nws thauj cov kua thiab roj.
