Ob leeg PFA thiab PTFE yog raw cov ntaub ntawv rau Teflonwire siv, PFA yam ntxwv yog corrosion, thiab kev sib txhuam coefficient ntawm PTFE nta yog tsawg heev, ces qhov txawv ntawm PFA PTFE yog dab tsi?
Qhov tsos:PFA translucent, PTFE ntshiab dawb opaque.
Kub tiv taus:PFA-200 degrees - + 260 degrees, PTFE-200 degrees - +250 degrees.
Cov duabntawm cov khoom siv raw: PFA yog granular, thiab PTFE yog hmoov.
PTFETeflon hlau: Thaum nws nyob rau hauv qhov kub thiab txias ntawm 327 ° C thiab qis dua, PTFE hlau yuav tsis cuam tshuam, txawm tias qhov kub thiab txias siab tshaj qhov melting point, lub rwb thaiv tsev sab nrauv tsis poob, thiab thaum kub qis dua. tshaj qhov melting point Outer rwb thaiv tsev yuav restore lub qub qub.
PFATeflon coatedhlauyog nyob rau hauv ib lub sij hawm luv luv ntawm 320 ° C nyob rau hauv ib tug luv luv lub sij hawm, thiab cov insulating txheej yuav combustion, thiab poob.
Nqe: PTFE hlau yog kim dua PFA Teflon hlau
