Mutsauko pakati peTeflon uye polytetrafluorohyle

PVDF iri PolyVinylidene Fluoride, iyo iri kutonyanya kuipa kupfuura F4 uye F46, ine yakadzika tembiricha kupesana (mutengo wakachipa zvakanyanya pane F4 uye F46).

PTFE (F4) iri polytetrafluorohlene, iyo ine tembiricha yakanaka uye kupokana kwekushora, uye kunogona kutsungirira kuora kwe chero svikiro. Ruvara rwakachena zvachose. Iyo inowanzoshandiswa kune mapapiro akafukidzwa-yakavezwa, mavharuvhu, zvisimbiso, tsvimbo, nezvimwe.

FEP (F46) iri polyperfluorohleryleyle, ruvara rwacho rwunoonekera, uye kupokana kwaro kwekora kwakaenzana neiyo yePTFE. Iyo inowanzoshandiswa kune fluorine-yakarongedzwa mapapu kana pombi yemukati. PFA TetraFluoroHerylene-PerfluoroLoxy vinyl Ethelmer (zvakare anozivikanwa se: Perfluorolkalene Alloy

Iyo makemikari zvivakwa zve pfafepptfe zvakafanana, asi fep inogona kungoshandiswa pazasi mazana maviri emadhigirii, uye ptfe haigoni kuiswa jekiseni yakaumbwa.

Teflon inonzi PolytetraFluoro Stalene in ChiRungu, inotaurwa nezvayo seTeflon, ptfe, F4 Teflon yakakamurwa muPTFE, FAP, PFA, ETFE

Akati wandei marudzi ekutanga:

Teflon ptfe:

PTFE (PolytetraFluoroHeryle) Non-Diging Coating inogona kushandiswa zvichiramba zvichienderera mberi ne290 ° C.00

Teflon fep:

FEP (Fluorinated ethylene propyne Copymer) Non-tsvimbo inovhara melts uye inoyerera kuti iite firimu risingapomeri panguva yekubheka. Iyo ine yakanakisa makemikari kugadzikana uye yakanaka isiri-tsvimbo zvivakwa. Iyo yakakwira yekushandisa tembiricha ndeye 200 ° C

Teflon PFA:

PFA (PERFLOWOKOLOKYL) YEMAHARA-STATER MOTONY, SEZVINONYANYA, KUSVIRA UYE KUFANIRA KUTI VAVE KUTI VAVANZE FILLID LICK YAKABUDA. Iko mukana wePFA ndiko kuti kune yakakwirira inoenderera ichishandisa tembiricha ye250 ° C, yakasimba kuomarara uye yakajairwa, uye inokodzera zvakanyanya kurwisa-kunamatira uye kwemakemikari ekuramba mashandisirwo emamiriro ekunze ekushisa.

Teflon etfe:

Etfe is a Coplymer yeEthylene uye tetrafluorootheryle, iyo yakanyanya kujairika fluorolene inoumba zvakanyanya kujairana nemakemikari akanakisa uye anogona kutsungirira kupisa kusvika pa150 ° Chanda basa racho kuenderera mberi.
