PTFE yog cov yas ruaj khov tshaj plaws tam sim no.Nws yog dav siv nyob rau hauv ntau yam lag luam nrog hnyav ib puag ncig.Vim nws qhov kev ua tau zoo heev, nws tau maj mam dhau los ua cov khoom tseem ceeb hauv cov khoom yas (Tag nrho yog hu ua Polytetrafluoroethylene).Yog li ntawd, kuj muaj ntau thiab ntau manufacturers tsim cov khoom zoo li no.PTFE tuaj yeem ua rau ntau hom khoom, xws li cov raj, rods, daim hlau, gaskets, films, thiab lwm yam., uas yog siv rau hauv ntau yam.
PTFE raj yog dab tsi?
Polytetrafluoroethylene (abbreviated li PTFE), feem ntau hu ua "Plastic King", yog ib lub siab molecular polymer tau los ntawm polymerizing tetrafluoroethylene li monomer, uas yog dawb los yog translucent.Cov khoom no tsis muaj cov pigments lossis additives, thiab muaj cov yam ntxwv ntawm acid thiab alkali tsis kam, tsis kam mus rau ntau yam organic solvents, thiab yuav luag insoluble nyob rau hauv tag nrho cov kuab tshuaj.Tsis tas li ntawd, PTFE muaj qhov kub thiab txias thiab tuaj yeem siv tau ntev ntawm -65 ° C ~ 260 ° C nyob rau hauv lub siab ib txwm.Nws yog tsim los ntawm paste extrusion txoj kev.PTFE tubing manufactured siv paste extrusion yog hloov tau thiab nws muaj peev xwm tsim PTFE tubing nrog puab diameters li me me li 0.3 hli mus txog rau ib tug siab tshaj plaws ntawm 100 hli thiab phab ntsa thicknesses me me li 0.1 hli mus rau 2 hli.Yog li ntawd, polytetrafluoroethylene (PTFE) tubing yog ib qho khoom siv ntau yam uas muaj ntau yam kev siv hauv ntau qhov kev lag luam sib txawv.
Vim li cas PTFE raj tau dav siv:
1. Kub kub kuj, insoluble nyob rau hauv tej hnyav.Nws tuaj yeem tiv taus qhov kub siab txog 300 ° C hauv ib lub sijhawm luv luv, thiab feem ntau tuaj yeem siv tsis tu ncua ntawm 200 ° C thiab 260 ° C, nrog rau qhov tseem ceeb thermal stability.
2. Tsis tshua muaj kub tsis kam, zoo mechanical toughness ntawm qhov kub thiab txias, txawm tias qhov kub thiab txias poob mus rau -65 ℃, nws yuav tsis ua embrittled, thiab nws muaj peev xwm tuav tau 5% elongation.
3. Corrosion resistant, inert rau feem ntau cov tshuaj thiab cov kuab tshuaj, resistant rau muaj zog acids thiab alkalis, dej thiab ntau yam organic solvents, tuaj yeem tiv thaiv qhov chaw ntawm txhua yam tshuaj corrosion.
4. Anti-aging, nyob rau hauv siab load, muaj ob qhov zoo ntawm hnav tsis kam thiab tsis-sticking.Qhov zoo tshaj plaws kev laus lub neej nyob rau hauv plastics.
5. High lubrication, qhov qis tshaj coefficient ntawm kev sib txhuam ntawm cov khoom siv.Lub coefficient ntawm kev sib txhuam hloov thaum lub load slides, tab sis tus nqi tsuas yog nyob nruab nrab ntawm 0.05-0.15.Yog li ntawd, nws muaj qhov zoo ntawm qhov pib ua haujlwm qis thiab ua haujlwm du rau kev ua cov bearings.
6. Tsis-adhesion yog qhov tsawg tshaj plaws ntawm qhov nro ntawm cov khoom siv, thiab tsis ua raws li cov khoom siv.Yuav luag txhua yam khoom yuav tsis lo rau nws.Cov yeeb yaj kiab nyias kuj tseem qhia tau cov khoom tsis zoo.
7. Nws tsis muaj ntxhiab tsw, saj tsis qab, tsis muaj tshuaj lom, lub cev tsis muaj zog, thiab tsis muaj qhov cuam tshuam tsis zoo thaum cog rau hauv lub cev raws li cov hlab ntsha thiab cov khoom nruab nrog ntev ntev.
8. Lub teeb yuag thiab yoog raws.Ua kom txo tau tus neeg teb xov tooj kev siv zog ua haujlwm.
Qee qhov kev siv ntawm PTFE raj:
1. Kev lag luam tshuaj
Vim tias lawv cov tshuaj tiv thaiv siab rau yuav luag txhua yam tshuaj, PTFE raj yog qhov zoo tagnrho rau siv hauv kev lag luam tshuaj.Qhov no suav nrog kev lag luam semiconductor.Cov txheej txheem niaj hnub hauv kev tsim khoom semiconductor xav tau kev ntsuas kev nyab xeeb thiab thauj cov kua corrosive (acids thiab bases).Cov no tuaj yeem ua rau lub raj xa khoom loj heev hauv lub sijhawm luv luv.
2. Kev lag luam tsheb
Nyob rau hauv lub tsheb cav, zoo tubing ua los ntawm PTFE yog siv rau roj evaporation thiab roj rails.Xws li roj hoses, turbocharger hoses, coolant hoses, tsis siv neeg nres hoses, maus taus nres hoses, diesel cav hoses, sib tw hoses thiab lub hwj chim steering hoses.Cov yam ntxwv ntawm qhov kub thiab txias tsis kam, kev kub siab tsis kam, hnav tsis kam thiab corrosion kuj ntawm PTFE raj ua rau nws muaj lub neej ua haujlwm ntev yam tsis muaj kev hloov ntau zaus.
3. 3D luam ntawv kev lag luam
Hauv 3D luam ntawv, cov hlua yuav tsum tau xa mus rau lub tshuab luam ntawv, uas yuav tsum tau ua nyob rau hauv qhov kub thiab txias.PTFE tubing yog qhov nyiam tshaj plaws polymer hauv kev lag luam 3D luam ntawv vim nws qhov kub thiab txias coefficient thiab tsis-stick zog, uas pab xaub cov khoom yooj yim ntawm lub nozzle.
4. Kev kho mob kev lag luam
Cov khoom tshwj xeeb ntawm PTFE hlab kuj suav nrog cov qauv yooj yim-rau-huv.Hauv kaum xyoo dhau los, PTFE tubing tau nce siv hauv cov khoom siv kho mob.Vim tias qhov coefficient qis ntawm kev sib txhuam ntawm PTFE tubing, nws txhais tau hais tias nws muaj qhov chaw du heev uas tsis muaj qhov ncauj qhov ntswg los yog pab cov kab mob loj hlob.Ntawm lawv, hoses yog siv rau cannulas, catheters, pipettes thiab endoscopes.
5. Kev lag luam zaub mov
Vim nws yooj yim tu thiab tsis-stick zog, PTFE tubing tuaj yeem siv rau hauv kev lag luam khoom noj.Tshwj xeeb, cov raj uas ua los ntawm PTFE tsis muaj qhov tsim nyog vim lawv lub cev tsis zoo thiab ua raws li US Food and Drug Administration cov lus qhia.Yog li ntawd, nws tau raug pov thawj tsis muaj mob nyob rau hauv kev sib cuag nrog yas thiab txhua yam khoom noj.
Kev yuav txoj cai PTFE tubing tsis yog tsuas yog xaiv cov kev qhia tshwj xeeb rau kev siv sib txawv.Ntau dua los xaiv cov chaw tsim khoom txhim khu kev qha.Besteflon Fluorine yas kev lag luam Co., Ltd. specializes nyob rau hauv zus tau tej cov zoo PTFE hoses thiab hlab rau 15 xyoo.Yog tias muaj lus nug thiab xav tau, thov koj xav tiv tauj peb kom paub ntau ntxiv tswv yim.
