(Cov ntsiab lus piav qhia) PTFE EPDM npauj npaim valve lub rooj
Teflon PTFE tseem hu ua polytetrafluoroethylene.Teflon PFA tseem hu ua soluble polytetrafluoroethylene.Ntau lub valve yuav tsis meej heev uas yog qhov zoo dua corrosion kuj rau npauj npaim li qub siv PTFE thiab PFA? Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm txhua tus? Qhov sib txawv ntawm qhov kub thiab txias, uas yog pheej yig dua?
Qhov txawv ntawm qhov
1.PFA: ib copolymer ntawm ib tug me me ntawm perfluoropropyl perfluorovinyl ether thiab polytetrafluoroethylene.2.PTFE: ib tug polymer compound tsim los ntawm polymerization ntawm tetrafluoroethylene.
Cov yam ntxwv sib txawv
Cov yam ntxwv ntawm PFA
(1) Cov khoom siv lead ua, tsis tshua muaj noo noo nqus.
([[2) kev ua haujlwm, yooj yim rau decompose thiab cov roj corrosive yog tsim thaum lub sij hawm decomposition. Lub moulding kub tsis pub dhau475 ° C, cov pwm yog rhuab rau 150 - 200 ° C, thiab cov dej puting tsis tshua muaj rau cov khoom ntws.
(3 Trasucent pelles, icjection molding thiab extrusion molding.Molding kub yog 350 - 400C, 475 ℃ thiab saum toj no yog ib qho yooj yim los ua kom muaj xim los yog blistering. Them rau qhov nyuaj ntawm demolding.
(4) Vim yog cov nyhuv corrosion ntawm cov khoom molten ntawm hlau, ntev - lub sij hawm ntau lawm yuav tsum tau chrome plating rau pwm.PTFE yam ntxwv
PTFE yam ntxwv
(1) Kub kub tsis kam: ntev - siv sijhawm kub 200 ~ 260 ℃;
(2) Tsis tshua muaj kub tsis kam: softer ntawm - 100 ℃;
(3) Corrosion kuj: resistant rau aqua regia thiab tag nrho cov organic solvents;
(4) Huab cua tsis kam: qhov zoo tshaj plaws kev laus lub neej ntawm cov yas;
(5) High lubrication: nrog qhov tsawg tshaj plaws coefficient ntawm kev sib txhuam (0.04) ntawm cov yas;
(6) Tsis yog - nplaum: Nws muaj qhov tsawg tshaj plaws ntawm qhov nro ntawm cov khoom siv yam tsis ua raws li cov khoom siv.
Qhov sib txawv loj tshaj plaws yog tias PFA yooj yim dua rau txheej txheem thiab kim dua PTFE, tab sis hauv kev xyaum PTFE muaj kev tiv thaiv corrosion zoo dua thiab kuj tiv taus qhov kub thiab txias.
