PI (Polyimide) Pauka, Rod, Pepa, Nā Mea Hana Hana CNC
ʻIke ʻia nā polyamides thermosetting no ke kūpaʻa wela, ke kūpaʻa kemika maikaʻi, nā waiwai mechanical maikaʻi loa, a me ke ʻano ʻalani/melemele. ʻO nā polyamides i hui pū ʻia me ka graphite a i ʻole ke aniani fiber reinforcements loaʻa nā ikaika flexural a hiki i 340 MPa (49,000 psi) a me flexural moduli o 21,000 MPa (3,000,000 psi). Hōʻike nā Thermoses polymer matrix polyamides i ke kolo haʻahaʻa a me ka ikaika tensile kiʻekiʻe. Mālama ʻia kēia mau waiwai ma ka hoʻohana mau ʻana i nā mahana a hiki i 232 °C (450 °F) a no nā huakaʻi pōkole, a hiki i 704 °C (1,299 °F).[11] ʻO nā ʻāpana polyimide i hoʻoheheʻe ʻia a me nā laminates he pale wela maikaʻi loa. ʻO nā mahana hana maʻamau no ia mau ʻāpana a me nā laminates mai ka cryogenic a hiki i nā mea ma mua o 260 °C (500 °F). ʻO nā polyamides ke kūpaʻa maoli i ka hoʻopau ʻana i ke ahi a ʻaʻole pono e hui pū ʻia me nā mea pale ahi. Lawe ka hapa nui i ka helu UL o VTM-0. Loaʻa i nā laminates polyimide ka hapalua o ke ola ma 249 °C (480 °F) o 400 mau hola.
ʻAʻole pili ʻia nā ʻāpana polyimide maʻamau e nā mea hoʻoheheʻe a me nā aila maʻamau - me nā hydrocarbons, esters, ethers, alcohols a me ferns. Kūʻē pū lākou i nā ʻakika nāwaliwali akā ʻaʻole ʻōlelo ʻia no ka hoʻohana ʻana i nā kaiapuni i loaʻa nā alkalis a i ʻole nā ʻakika inorganic. ʻO kekahi mau polyamides, e like me CP1 a me CORIN XLS, he solvent-soluble a hōʻike i ka mālamalama optical kiʻekiʻe. Hāʻawi nā waiwai solubility iā lākou i nā noi lapaʻau a me ka wela haʻahaʻa.
Nā hiʻohiʻona PI
ʻO PI kona polimer pale ahi ponoʻī, ʻaʻole ia e wela i ka wela kiʻekiʻe
Mechanical waiwai haʻahaʻa sensitivity i ka wela
Loaʻa i ka mea i hiki ke kala kala, hiki ke hoʻokō i nā koi like ʻole o ka hoʻohālikelike kala
ʻOi aku ka maikaʻi o ka hana wela: ʻO ka wela kiʻekiʻe a me ke kūpaʻa haʻahaʻa haʻahaʻa
ʻO ka hana uila maikaʻi loa: Hoʻomoe uila kiʻekiʻe
Kahua noi nui PI
Hoʻohana nui ʻia i nā mīkini, nā mea kani, nā ʻāpana kaʻa, ka uila a me ka uila, ke kaʻaahi, nā mea hana hale, nā kamaʻilio, nā mīkini textile, nā haʻuki a me nā huahana leʻaleʻa, nā paipu aila, nā pahu wahie a me nā huahana ʻenekinia pololei.
ʻO nā mea polyimide he māmā, maʻalahi, kū'ē i ka wela a me nā kemika. No laila, hoʻohana ʻia lākou i ka ʻoihana uila no nā kaula maʻalahi a ma ke ʻano he kiʻi insulating ma ka uea magnet. No ka laʻana, i loko o kahi kamepiula kamepiula, ʻo ke kaula e hoʻopili ai i ka papa loiloi nui i ka hōʻike (pono e hoʻololi i kēlā me kēia manawa e wehe ʻia a pani ʻia paha ka kamepiula) he kumu polyimide me nā mea hoʻokele keleawe. ʻO nā hiʻohiʻona o nā kiʻiʻoniʻoni polyimide ʻo Apical, Kapton, UPILEX, VTEC PI, Norton TH a me Kaptrex.
ʻO kahi hoʻohana hou aʻe o ka resin polyimide ma ke ʻano he insulating a me ka passivation layer i ka hana ʻana i nā ʻāpana hoʻohui a me nā pahu MEMS. ʻO nā papa polyimide he elongation mechanical maikaʻi a me ka ikaika tensile, e kōkua pū ana i ka hoʻopili ʻana ma waena o nā papa polyimide a i ʻole ma waena o ka papa polyimide a me ka papa metala i waiho ʻia.
