Cov lus nug nquag
Qhov txawv ntawm FFKM thiab FKM yog dab tsi?
FFKM tuav qhov kub siab dua (txog 327℃vs 200℃rau FKM), tiv thaiv ketones, esters, amines, muaj zog acids, thiab ntshav - tag nrho cov uas tawm tsam FKM. Txawm li cas los xij, FFKM raug nqi 10-50 npaug ntxiv. Xaiv FFKM thaum kub siab tshaj 230℃lossis thaum raug rau cov xov xwm nruj.
Vim li cas FFKM thiaj li kim?
FFKM yuav tsum muaj kev sib txuas ntawm perfluorinated monomers thiab tsuas yog tsim los ntawm ob peb tus neeg muag khoom (DuPont, 3M, Daikin, Solvay). Cov txheej txheem tsim khoom yog kim, ua rau nws 10-50 npaug ntawm tus nqi ntawm FKM. Siv nws tsuas yog thaum FKM tsis tuaj yeem ua raws li cov kev pabcuam.
Cov ntaub ntawv dab tsi xav tau rau FFKM kev cai hais?
Muab: (1) qhov siab tshaj qhov ntsuas kub tsis tu ncua (kom xaiv qib raug - 230/260/300/327 degree), (2) cov tshuaj lom neeg thiab nws cov concentration (xws li 98% H₂SO₄, MEK), (3) seb nws puas yog rau kev siv semiconductor (yuav tsum tau hlau- ion{11}), thiab tsis muaj plasma tam sim no (yuav tsum tau plasma{13}}resistant gra
