Izinto eziluncedo zePEEK—–uKuxhathisa ubushushu obuphezulu kunye noKuxhathisa ukuMhlwa

I-PEEK (i-poly-ether-ether-ketone) i-polymer ekhethekileyo equkethe ibhondi enye ye-ketone kunye neebhondi ezimbini ze-ether kwikhonkco eliphambili.

Ngenxa yesixa esikhulu se-benzene ring structure, iPEEK ibonisa iimpawu ezigqwesileyo ezibanzi, ezifana nokumelana nobushushu obuphezulu, ukumelana nokugqwala, iipropathi ezilungileyo zomatshini, ukumelana nempembelelo, ukuzithambisa, ukubuyiswa komlilo njalo njalo.

Namhlanje, sithetha ngeenzuzo ze-PEEK malunga nokumelana nokushisa okuphezulu kunye nokumelana nokubola.

1.I-PEEK yokumelana nobushushu obuphezulu

Kumzi-mveliso wepetrochemical, izinto zePEEK zisetyenziswa ikakhulu ngenxa yokumelana nobushushu obuphezulu, ke zeziphi iingenelo zePEEK xa zithelekiswa nezinye iiplastiki zobunjineli ezikhethekileyo ze-thermoplastic?

Umzobo 1. Indawo yokunyibilika kunye nedayagram yobushushu bokusetyenziswa kwexesha elide yeeplastiki zobunjineli ezisetyenziswa ngokuqhelekileyo ze-thermoplastic

Ukusuka kwi-Fig1., sinokubona ukuba indawo yokunyibilika kunye nobushushu benkonzo yexesha elide ye-PEEK iphezulu kunezinye iiplastiki ezine ze-thermoplastic ezikhethekileyo zobunjineli. Ke ngoko, izixhobo ze-PEEK zinokubonisa ukumelana nobushushu.

Ukusebenza okuthe ngqo kokumelana nobushushu obuphezulu be-PEEK kunokuvavanywa ngokugoba okuphezulu kobushushu kunye noxinzelelo oluphezulu lobushushu.

Njengoko kubonisiwe kulo mfanekiso ulandelayo:

Umfanekiso we-2 PEEK5600G kunye ne-PEEK5600CF30.

Ipropathi yokugoba ubushushu obuphezulu kunye nejika loxinzelelo lobushushu obuphezulu

Inokubonwa kwi-Fig.2 ukuba, njengazo zonke iiplastiki, iimpawu zabo zomatshini ziyancipha ngokuthe ngcembe ngokunyuka kweqondo lokushisa. Nangona kunjalo, ngenxa yokumelana nobushushu obugqwesileyo be-PEEK yayo, isenokugcina malunga ne-70% yentsebenzo yokuqala kwi-100C.

2. I-PEEK yokumelana nomhlwa

Kwimveliso yangempela kunye nobomi, izinto ze-PEEK nazo zisebenzisa ukuxhathisa ukubola, njenge-PEEK capillaries yezixhobo zokuhlalutya, i-PEEK joints kunye nokunye.

Tab.1 Iitafile zokuxhathisa ukonakala kweeplastiki ezininzi zobunjineli ezizodwa

Inokubonwa kwi-Tab.1 ukuba ukuxhathisa kokubola kwe-PPS ngokusisiseko kuyafana naleyo ye-PEEK, ngelixa ukuchasana kokubola kwe-PPSU, i-PEI, i-PI kubi kunoko kwe-PEEK.

Iimveliso ze-PEEK zinokuxhathisa iikhemikhali ezibalaseleyo. Kwiikhemikhali eziqhelekileyo, kuphela i-asidi ye-sulfuric egxininisiweyo inokuyinyibilika okanye iyitshabalalise, kwaye ukuxhathisa kwayo kwe-corrosion kufana nentsimbi ye-nickel.
