1. ʻewlelo Hoʻākāka


  3240 pepa epoxy hoʻohana nui ʻia e like me ka mea insulation i nā lako electromechanical ma muli o kona kiʻekiʻe mechanical a me nā waiwai uila, haʻahaʻa haʻahaʻa wai, kala māmā, nani a maʻemaʻe. Eia nō naʻe, me ka hoʻomohala ʻana o ka ʻoihana kaʻa, ua kau ʻia nā koi kiʻekiʻe no ka hiki i nā mea insulation ke hoʻololi i nā wahi paʻakikī, a ʻike ʻia ka pōʻino o nā leakage traces. No laila, he mea koʻikoʻi koʻikoʻi ka hoʻomohala ʻana i kahi papa epoxy me ke kūʻē ʻana i nā ala uila.


  E like me ke kūlana o kēia manawa o ka papa epoxy F-grade home, bisphenol A epoxy blade DS curing system e hoʻohana nui ʻia. Ma kēia kumu, ua hoʻomaopopo ʻia ʻo ka alicyclic epoxy resin he mau waiwai uila kiʻekiʻe kiʻekiʻe a me ka index resistance trace uila, a he ʻokoʻa loa ia mai ka bisphenol A epoxy resin i ka hana kemika a me ka hana. Hoʻoholo kona ʻano kemika i ka haʻahaʻa o ka hana pane ma mua o ka bisphenol A epoxy resin. I ka hana ʻana me nā amine, ʻoi aku ka lohi o ka wikiwiki o ka epoxide alicyclic. No laila, ua mākaukau e hoʻololi i kahi ʻāpana o ka bisphenol A-type epoxy me ka epoxy alicyclic, a hoʻoponopono iā ia ma ke kumu o ke kaʻina hana, e hoʻohui i nā accelerants e hoʻoponopono i ka manawa gelation o ka resin.

a) Hoʻohui ʻia o ka epoxy resin e hiki ke kū i ka uila


i. Mea waiwai


  E-44 epoxy resin, huahana hana; Alicyclic epoxy resin, nā huahana ʻoihana; 4.4-diaminodiphenyl benzene, huahana hana; Toluene / waiʻona i hui pū ʻia me ka mea hoʻoheheʻe, huahana ʻoihana; Mea hoʻokē, reagent.

iii. Kaʻina hana synthetic


  E hoʻohui i ka E-44 epoxy resin, alicyclic epoxy resin a me DDS i loko o ka ipu hao e like me ke ʻano, wela a hoʻoulu. Ma hope o ka pane ʻana i kahi mahana no kekahi manawa, hoʻohui i ka polyphenylene, hoʻoponopono i ka manawa gelation me kahi mea hoʻolaha e hoʻokō i ka waiwai i ʻōlelo ʻia o nā koi ʻenehana, hoʻohui i ka waiʻona toluene i hui pū ʻia, ʻoluʻolu, kānana a me ka puʻupuʻu e loaʻa ai kahi hopena uila epoxy resin. .


iv. Nā waiwai resin


  E nānā i ka Papa 1 no nā kuhikuhi kikoʻī hana maʻamau o ka hoʻoheheʻe epoxy resin pale uila


Nā waiwai hoʻonā resin

b) Ka hoʻomākaukau ʻana i ka lole aniani epoxy prepreg me ke kūʻē ʻana i ke ala uila

Hoʻopili ʻia ka lole aniani manuahi alkali i mālama ʻia me ka hui hui ʻana me ka epoxy resin solution, a ua hoʻomākaukau ʻia ka prepreg ma ka mīkini hoʻohālikelike kū i ka hopena pālua e like me nā kūlana kaʻina: 1.0m/s ~ 5.0m /s; Ka wela o ka hale kiaʻi: 100 ℃ ~ 160 ℃.

3. Ka hopena a me ke kūkākūkā


a) Heat kū'ē o ka uila meheu epoxy aniani lole laminate


  Ke hoʻohana nei kā mākou hui iā Netzsch (model: dsc200f3) mai Kelemānia e hoʻāʻo i ka Tg o ka pauka laminate ma o ka calorimetry scanning differential (DSC). ʻO ka Tg he 160 ~ 170 ℃, a ʻo ka helu wela o ka resin he 177 ℃ i helu ʻia e like me ka ʻikepili wikiwiki o ka wela wela. No laila, hiki ke hoʻohana ʻia kēia laminate e like me ka papa insulation material


b) Mechanical a me nā waiwai uila o ka papa epoxy pale uila


  Hōʻike ʻia nā waiwai electromechanical o ka laminate ma ka Papa 4. ʻO nā helu helu helu ma ka Papa 4 ʻo ia nā ʻenehana loea o epgc306 ma iec60893-3-2. Hiki ke ʻike ʻia mai kēia papa ʻaina i nā mea i ana ʻia a pau i nā koi kuhikuhi.

  ʻO ka hana o Pepa Lamina Epoxy ʻO ka mea mua e pili ana i ka hana o ka resin matrix. Ma lalo o ka resin matrix i hoʻoholo ʻia a me nā mea hoʻoikaika, ʻo ka mahana, ka manawa a me ke kaomi he mea nui i ka hana o nā laminates. I ka hui pū ʻana me nā mea hana a ka hui a me nā kūlana hana, ʻimi ʻia a hōʻuluʻulu ʻia kahi hoʻonohonoho o nā ala kaʻina hana no ka hana ʻana i nā laminates kiʻekiʻe, e hana ana i nā palapala kaʻina hana a hōʻoia i ka paʻa o ka maikaʻi o ka huahana o nā kikoʻī like ʻole.

  He kiʻekiʻe ka mīkini a me nā waiwai uila i ka uila trace resistant epoxy glass cloth laminate, a he kiʻekiʻe kiʻekiʻe o ka uila trace resistance. He kūpono ia no nā ʻāpana hana insulation a me nā ʻāpana mechanical i ka papa F motors a me nā lako uila. He kūpono no ka wela kiʻekiʻe, ka haʻahaʻa, ka pollution a me nā wahi ʻino ʻē aʻe. ʻO ka papa kuhikuhi hana holoʻokoʻa o ka laminate e hui me ka ʻenekini ʻenehana o epgc306 ma iec60893-3-2. I kēia manawa hiki ke hana nui ʻia me nā pono waiwai maikaʻi.
