He aha ka PEEK?
Polyether ether ketone(PEEK) he mea polimer aromatic thermoplastic.He ʻano ʻenehana loea kūikawā me ka hana maikaʻi loa, ʻoi aku ka hōʻike ʻana i ke kūpaʻa wela super ikaika, ke kūpaʻa friction a me ke kūpaʻa dimensional.Hoʻohana nui ʻia ia i ka aerospace, pūʻali koa, kaʻa, lāʻau lapaʻau a me nā kula ʻē aʻe.
Hana PEEK kumu
Loaʻa i ka PEEK ka ikaika mechanical kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka hopena, ka pale ahi, ka ʻakika a me ke kūpaʻa alkali, ke kūpaʻa hydrolysis, ka pale abrasion, ka luhi luhi, ka pale ʻana i ka radiation a me nā waiwai uila maikaʻi.
ʻO ia ke kūlana kiʻekiʻe o ka pale wela i nā plastic engineering kūikawā.
Hiki i ka mahana lawelawe lōʻihi mai -100 ℃ a 260 ℃.
ʻOi aku ka maikaʻi o nā hiʻohiʻona kūpaʻa o ka PEEK plastic maka.He liʻiliʻi ka hopena o ke kaiapuni me ka nui o ka mahana a me ka haʻahaʻa i ka nui o nā ʻāpana PEEK, a ʻo ka PEEK injection molding shrinkage rate he liʻiliʻi, ʻo ia ka mea i ʻoi aku ka kiʻekiʻe o ka nui o nā ʻāpana PEEK ma mua o nā plastic plastic, hiki ke hoʻokō i nā koi o kiʻekiʻe dimensional pololei ma lalo o ka hana.
Loaʻa i ka PEEK nā hiʻohiʻona hydrolysis kūpaʻa wela.
I loko o ke kaiapuni o ke kiʻekiʻe wela a me ka haʻahaʻa haʻahaʻa loa ka wai absorption, e like me ka nylon a me nā plastics ma muli o ka wai absorption a me ka nui o nā loli maopopo.
Loaʻa i ka PEEK ka paʻakikī a me ke kūpaʻa luhi, hoʻohālikelike ʻia me nā alloys, a hiki ke hoʻohana ʻia no ka manawa lōʻihi i ke koi ʻana i nā wahi hana.No ka hoʻololiʻana i ke kila, ka aluminika, ke keleawe, ka titanium, ka ptFE a me nā mea hana kiʻekiʻe'ē aʻe, e hoʻonui i ka hana o ka mīkini i ka manawa like e hoʻemi nui i ke kumukūʻai.
He palekana maikaʻi ka PEEK.Hōʻike nā hualoaʻa hoʻāʻo UL o ka mea ʻo PEEK's flame retardation index is Grade V-0, ʻo ia ka pae maikaʻi loa o ka hoʻopaʻa ahi.ʻO ka hoʻopau ʻana o PEEK (ʻo ia hoʻi, ka nui o ka uahi i hana ʻia i ka wā e hoʻopau mau ai) ʻo ia ka haʻahaʻa loa o nā plastic.
He haʻahaʻa hoʻi ka hiki ʻole o ke kinoea o PEEK (ka ʻike kinoea i hana ʻia i ka wā i hoʻoheheʻe ʻia i ka wela kiʻekiʻe).
Ka moolelo o PEEK
ʻO PEEK ka mea ma ka piko o ka pyramid plastic, a he liʻiliʻi nā hui o ka honua i mākaukau i ke kaʻina polymerization.
Ua hoʻomohala ʻia ʻo PEEK e ICI i nā makahiki 1970.Ma muli o kāna mau waiwai mechanical a me nā waiwai hoʻoponopono, ua lilo ia i hoʻokahi o nā plastics ʻenehana kūikawā kūikawā.
Ua hoʻomaka ka ʻenehana PEEK o Kina i ka makahiki 1980.Ma hope o nā makahiki o ka noiʻi paʻakikī, ua hoʻomohala ʻo Jilin University i ke kaʻina hana synthesis resin PEEK me nā kuleana waiwai naʻauao kūʻokoʻa.ʻAʻole wale ka hana o ka huahana i hiki i ka pae PEEK haole, akā ua hoʻokumu ʻia nā mea maka a me nā mea hana ma Kina, e hōʻemi pono ana i ke kumukūʻai hana.
I kēia manawa, ʻoi aku ka nui o ka ʻoihana PEEK o Kina, me ka maikaʻi a me nā huahana like me nā mea hana haole, a ʻoi aku ka haʻahaʻa o ke kumukūʻai ma mua o ka mākeke honua.ʻO ka mea e pono e hoʻomaikaʻi ʻia ʻo ka waiwai like ʻole o PEEK.
He lālā ʻo Victrex no ka ICI o Beretania a hiki i ka wā i wili ʻia ai.
Ua lilo ia i mea hana PEEK mua ma ka honua.
ʻO ka noi o PEEK
1. Nā noi Aerospace: pani i ka alumini a me nā mea metala ʻē aʻe no nā ʻāpana mokulele, no nā puʻupuʻu puʻupuʻu rocket, bolts, nuts a me nā ʻāpana no nā ʻenekini rocket.
2. Hoʻohana i loko o ke kahua uila: insulation film, connector, printed circuit board, high temperature connector, integrated circuit, cable coil skeleton, insulation coating, etc.
3. Nā noi i nā mīkini kaʻa: nā bearings automotive, gaskets, sila, clutches, brakes a me nā ʻōnaehana ea.Ua hoʻomaka ʻo Nissan, NEC, Sharp, Chrysler, GENERAL Motors, Audi, Airbus a me nā mea ʻē aʻe e hoʻohana i nā mea i ka nui.
4. Nā noi i ka lāʻau lapaʻau: iwi artificial, denture implant base, lāʻau lapaʻau pono e hoʻohana pinepine ʻia.
