PEEK (poly-ether-ether-ketone) ipolymer yakakosha iyo ine ketone bond uye maviri ether mabhondi mucheni huru.
Nekuda kwehukuru hwayo hwebenzene ring dhizaini, PEEK inoratidza zvakanakisa zvinhu, senge yakanakisa kupisa tembiricha, corrosion resistance, good mechanical properties, impact resistance, self-lubrication, flame retardant nezvimwe.
Nhasi, isu tinotaura nezvezvakanakira zvePEEK maererano nepamusoro tembiricha kuramba uye corrosion resistance.
1.PEEK yakanyanya kupisa tembiricha kuramba
Muindasitiri yepetrochemical, PEEK zvinhu zvinonyanya kushandiswa nekuda kwekupisa kwayo kupisa, saka ndezvipi zvakanakira PEEK zvichienzaniswa nemamwe thermoplastic special engineering mapurasitiki?
Fig 1. Melting point uye kushandiswa kwenguva refu tembiricha dhiyagiramu yeanowanzo shandiswa thermoplastic engineering mapurasitiki.
Kubva Fig1., tinogona kuona kuti kunyungudika uye tembiricha yenguva refu yePEEK yakakwira kupfuura iyo yemamwe mana thermoplastic special engineering mapurasitiki.Naizvozvo, PEEK zvinhu zvinogona kuratidza zvakanakisa kupisa kupisa.
Iyo chaiyo mashandiro ekukwirira tembiricha yePEEK inogona kuyedzwa nekukotama kwekushisa kwakanyanya uye kudzvanywa kwekushisa kwepamusoro.
Sezvinoratidzwa mumufananidzo unotevera:
Fig.2 PEEK5600G uye PEEK5600CF30.
Yepamusoro tembiricha yekukotama pfuma uye yakanyanya tembiricha yekumanikidza curve
Inogona kuonekwa kubva Fig.2 kuti, kufanana nemapurasitiki ose, maitiro avo emagetsi anoderera zvishoma nezvishoma nekuwedzera kwekushisa.Nekudaro, nekuda kwekunaka kwekushisa kwekupokana kwePEEK yayo, ichiri kukwanisa kuchengetedza inosvika makumi manomwe muzana ekutanga kuita pa100C.
2. PEEK super corrosion resistance
Mukugadzirwa uye hupenyu chaihwo, PEEK zvinhu zvinoshandisawo corrosion resistance, sePEEK capillaries for analytical instruments, PEEK joints nezvimwe zvakadaro.
Tab.1 Corrosion resistance tables emapurasitiki akati wandei anokosha einjiniya
Zvinogona kuonekwa kubva kuTab.1 kuti kupikisa kwePPS kwakafanana neiyo yePEEK, nepo kupikisa kwePPSU,PEI,PI kwakaipa kudarika kwePEEK.
PEEK zvigadzirwa zvine yakanakisa makemikari kuramba.Mumakemikari akafanana, chete concentrated sulfuric acid inogona kuinyungudutsa kana kuiparadza, uye kushorwa kwayo kwakafanana neyesimbi ye nickel.
