(Tlhaloso e akaretsang)PTFE EPDM setulo sa valve ea serurubele
Teflon PTFE e boetse e tsejoa e le polytetrafluoroethylene.Teflon PFA e boetse e tsejoa e le soluble polytetrafluoroethylene.Litheko tse ngata tsa li-valve ha li hlake hantle hore na ke ho hanyetsa ho hong ho molemo bakeng sa li-valve tsa serurubele tse sebelisang PTFE le PFA? Melemo le mefokolo ea e 'ngoe le e 'ngoe ke efe? Phapang ea ho hanyetsa mocheso, e leng theko e tlaase?
E fapaneng ka tlhaho
1.PFA: copolymer e nyenyane ea perfluoropropyl perfluorovinyl ether le polytetrafluoroethylene.2.PTFE: motsoako oa polymer o entsoeng ka polymerization ea tetrafluoroethylene.
Litšobotsi tse fapaneng
Litšobotsi tsa PFA
(1) Lisebelisoa tsa kristale, ho monya mongobo o tlase. E ka sebetsoa ka lihlahisoa ka mekhoa ea ts'ebetso ea thermoplastic.
. Mocheso o bolileng ha o fetelle475 ° C, hlobo e futhumetse ho 150 ° -
(3 trasucent pelles, ijection molding and extrusion molding.Molding molding is 350-400C, 475℃ and above are easy to causeis coloration or blistering. Ela hloko bothata ba ho phunya.

PTFE Tšobotsi
(1) Ho hanyetsa mocheso o phahameng: nako e telele - mocheso oa tšebeliso ea nako e telele 200 ~ 260 ℃;
(2)Ho hanyetsa mocheso o tlase: ho bonolo ho -100℃;
(3) Corrosion resistance: e hanana le aqua regia le metsoako eohle ea manyolo;
(4) Ho hanyetsa boemo ba leholimo: bophelo bo botle ba botsofali ba polasetiki;
(5)Lubrication e phahameng: e nang le coefficient e nyane haholo ea khohlano (0.04) har'a lipolasetiki;

Phapang e kholo ke hore PFA e bonolo ho e sebetsa ebile e theko e boima ho feta PTFE, empa ha e le hantle PTFE e na le matla a ho thibela kutu 'me e boetse e hanyetsa mocheso o phahameng.
