Melemo ea PEEK—–Ho Hanyetsa Mocheso o Phahameng le ho Thibela ho Rua

Corrosion Resistance1

PEEK (poly-ether-ether-ketone) ke polymer e khethehileng e nang le tlamo e le 'ngoe ea ketone le li-ether tse peli tsa ketane e kholo.

Corrosion Resistance2Ka lebaka la sebopeho sa eona se seholo sa lesale la benzene, PEEK e bonts'a lisebelisoa tse ngata tse felletseng, joalo ka ho hanyetsa mocheso o phahameng o phahameng, ho hanyetsa kutu, thepa e ntle ea mochini, ho hanyetsa tšusumetso, ho itlotsa, ho thibela lelakabe joalo-joalo.

Kajeno, re bua ka melemo ea PEEK mabapi le ho hanyetsa mocheso o phahameng le ho hanyetsa kutu.

1.PEEK e hanyetsa mocheso o phahameng haholo

Khanyetso ea Corrosion3

Indastering ea petrochemical, thepa ea PEEK e sebelisoa haholo-holo ka lebaka la ho hanyetsa mocheso o phahameng, joale melemo ea PEEK ke efe ha e bapisoa le li-plastiki tse ling tse khethehileng tsa thermoplastic?

Corrosion Resistance4Setšoantšo sa 1. Sebaka sa ho qhibiliha le setšoantšo sa mocheso oa nako e telele oa li-plastiki tsa boenjiniere tsa thermoplastic

Ho tloha ho Fig1., re ka bona hore ntlha ea ho qhibiliha le mocheso oa nako e telele oa ts'ebeletso ea PEEK li phahametse tsa tse ling tse 'nè tse khethehileng tsa polasetiki tsa thermoplastic. Ka hona, lisebelisoa tsa PEEK li ka bontša ho hanyetsa mocheso o babatsehang.

Ts'ebetso e ikhethileng ea ho hanyetsa mocheso o phahameng oa PEEK e ka lekoa ka ho kobeha ha mocheso o phahameng le khatello e phahameng ea mocheso.

Joalokaha ho bontšitsoe setšoantšong se latelang:

Corrosion Resistance5

Setšoantšo sa 2 PEEK5600G le PEEK5600CF30.

Mocheso o phahameng o kobehang thepa le mocheso o phahameng oa compression curve

E ka bonoa ho Fig.2 hore, joaloka lipolasetiki tsohle, thepa ea bona ea mechine e fokotseha butle-butle ka ho eketseha ha mocheso. Leha ho le joalo, ka lebaka la ho hanyetsa mocheso o babatsehang oa PEEK ea eona, e ntse e ka boloka hoo e ka bang 70% ea ts'ebetso ea pele ho 100C.

2. PEEK super corrosion resistance

Corrosion Resistance6Tlhahisong ea sebele le bophelo, lisebelisoa tsa PEEK li boetse li sebelisa ho hanyetsa kutu, joalo ka li-capillaries tsa PEEK bakeng sa lisebelisoa tsa ho hlahloba, li-PEEK tse ling joalo-joalo.

Tab.1 Litafole tsa ho hanyetsa kutu tsa lipolasetiki tse khethehileng tsa boenjiniere

Ho ka bonoa ho Tab.1 hore khanyetso ea kutu ea PPS ha e le hantle e tšoana le ea PEEK, athe khanyetso ea kutu ea PPSU,PEI,PI e mpe ho feta ea PEEK.

Lihlahisoa tsa PEEK li na le khanyetso e ntle ea lik'hemik'hale. Lik'hemik'haleng tse tloaelehileng, ke feela sulfuric acid e nang le concentrated e ka e qhaqha kapa ea e senya, 'me khanyetso ea eona ea ho senya e tšoana le ea tšepe ea nickel.
