Faa'iidooyinka PEEK—– Iska caabbinta heerkulka sare iyo iska caabinta daxalka

PEEK (poly-ether-ether-ketone) waa polymer gaar ah oo ka kooban hal ketone bond iyo laba curaarta ether ee silsiladda weyn.

Sababtoo ah qadarkeeda weyn ee qaab dhismeedka giraanta benzene, PEEK waxay muujineysaa sifooyin dhammaystiran oo heer sare ah, sida iska caabin heerkul sare oo heer sare ah, iska caabbinta daxalka, sifooyinka farsamada ee wanaagsan, caabbinta saamaynta, saliidaynta, ololka iyo wixii la mid ah.

Maanta, waxaan ka hadlaynaa faa'iidooyinka PEEK marka la eego iska caabbinta heerkulka sare iyo iska caabinta daxalka.

1.PEEK iska caabin heerkul sare ah oo aad u sarreeya

Warshadaha petrochemical, walxaha PEEK waxaa inta badan loo isticmaalaa sababtoo ah caabbinta heerkulka sare, markaa waa maxay faa'iidooyinka PEEK marka la barbar dhigo balaastikada kale ee gaarka ah ee thermoplastic?

Jaantuska 1. Barta dhalaalka iyo jaantuska heerkulka isticmaalka muddada-dheer ee balaastikada injineernimada heerkulbeegga ee inta badan la isticmaalo

Laga soo bilaabo shaxanka 1., waxaynu ka arki karnaa in barta dhalaalaysa iyo heerkulka adeega muddada-dheer ee PEEK ay ka sarreeyaan kuwa kale ee afarta balaastikada gaarka ah ee injineernimada.Sidaa darteed, walxaha PEEK waxay muujin karaan iska caabin kulayl oo aad u fiican.

Waxqabadka gaarka ah ee caabbinta heerkulka sare ee PEEK waxaa lagu tijaabin karaa foorarsi heerkul sare ah iyo cadaadis heerkul sare ah.

Sida ka muuqata shaxanka soo socda:

Sawirka.2 PEEK5600G iyo PEEK5600CF30.

Hantida foorarsiga heerkulka sare iyo qalooca heerkulka sare

Waxaa laga arki karaa Fig.2 in, sida balaastikada oo dhan, sifooyinkooda farsamaysan ayaa si tartiib tartiib ah hoos ugu dhacaya kororka heerkulka.Si kastaba ha noqotee, sababtoo ah iska caabbinta heerkulka aadka u fiican ee PEEK, waxay wali sii wadi kartaa ilaa 70% waxqabadka asalka ah ee 100C.

2. PEEK iska caabbinta daxalka sare

Wax soo saarka dhabta ah iyo nolosha, walxaha PEEK waxay sidoo kale isticmaalaan caabbinta daxalka, sida PEEK capillaries ee qalabka falanqaynta, kala-goysyada PEEK iyo wixii la mid ah.

Tab.1 Miisaska iska caabinta daxalka ee dhowr balaastiig injineernimo oo gaar ah

Waxaa laga arki karaa Tab.1 in iska caabbinta daxalka ee PPS asal ahaan la mid tahay tan PEEK, halka iska caabbinta daxalka ee PPSU,PEI,PI ay ka sii xun tahay tan PEEK.

Alaabta PEEK waxay leeyihiin iska caabin kiimiko oo heer sare ah.Kiimikooyinka caadiga ah, sulfuric acid kaliya ayaa milmi karta ama baabi'in karta, iska caabinteeda daxalka waxay la mid tahay tan birta nikkel.
