Nā Pōmaikaʻi o ka PEEK—–Kuʻe i ka wela kiʻekiʻe a me ke kū ʻana i ka ʻino

ʻO PEEK (poly-ether-ether-ketone) he polymer kūikawā i loaʻa hoʻokahi paʻa ketone a me ʻelua mau paʻa eter i ke kaulahao nui.

Ma muli o ka nui o ka nui o ke apo benzene, hōʻike ʻo PEEK i nā waiwai ākea maikaʻi loa, e like me ke kūpaʻa kiʻekiʻe kiʻekiʻe, ka pale ʻana i ka corrosion, nā waiwai mechanical maikaʻi, ka hopena hopena, ka lubrication ponoʻī, ka pale ahi a pēlā aku.

I kēia lā, ke kamaʻilio nei mākou e pili ana i nā pono o ka PEEK ma ke ʻano o ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa corrosion.

1.PEEK pale wela kiʻekiʻe loa

I ka ʻoihana petrochemical, hoʻohana nui ʻia ka mea PEEK ma muli o kona kūpaʻa kiʻekiʻe o ka wela, no laila he aha nā mea maikaʻi o PEEK i hoʻohālikelike ʻia me nā plastics ʻenehana kūikawā thermoplastic?

Fig 1. Ka helu heheʻe a me ka hoʻohana lōʻihi ʻana i ke kiʻikuhi wela o nā mea i hoʻohana mau ʻia i ka ʻenekinia thermoplastic

Mai Fig1., hiki iā mākou ke ʻike ʻoi aku ka kiʻekiʻe o ka helu hoʻoheheʻe a me ka mahana lawelawe lōʻihi o PEEK ma mua o nā mea ʻehā ʻē aʻe thermoplastic special engineering plastics. No laila, hiki i nā mea PEEK ke hōʻike i ka pale wela maikaʻi loa.

Hiki ke ho'āʻo ʻia ka hana kikoʻī o ke kūpaʻa wela kiʻekiʻe o PEEK e ka piko wela kiʻekiʻe a me ke kaomi wela kiʻekiʻe.

E like me ka mea i hōʻike ʻia ma kēia kiʻi:

Fig.2 PEEK5600G a me PEEK5600CF30.

Kiʻekiʻe wela piʻo waiwai a me ka wela kiʻekiʻe pōʻai kaomi

Hiki ke ʻike ʻia mai Fig.2, e like me nā plastics a pau, e emi mālie ko lākou mau waiwai me ka piʻi ʻana o ka mahana. Eia nō naʻe, ma muli o ke kūpaʻa wela maikaʻi o kāna PEEK, hiki iā ia ke mālama ma kahi o 70% o ka hana mua ma 100C.

2. PEEK kūʻē ʻino loa

I ka hana maoli a me ke ola, hoʻohana pū nā mea PEEK i ke kūpaʻa corrosion, e like me PEEK capillaries no nā mea analytical, PEEK joints a pēlā aku.

Tab.1 Nā papa ʻaina kūʻē i ka ʻino o kekahi mau mea ʻenekinia kūikawā

Hiki ke ʻike ʻia mai Tab.1 ʻo ke kūpaʻa ʻino o ka PPS ma ke ʻano like me ka PEEK, ʻoiai ʻoi aku ka ʻino o ka pale ʻana o PPSU,PEI,PI ma mua o ka PEEK.

Loaʻa i nā huahana PEEK ke kūpaʻa kemika maikaʻi loa. I loko o nā kinikini maʻamau, hiki ke hoʻoheheʻe a hoʻopau paha i ka ʻakika sulfuric concentrated, a ua like kona kūpaʻa ʻana me ke kila nickel.
