Ke alakaʻi o ka hoʻomohala ʻana i ka Pepa Epoxy Kūʻē Uila

1. ʻewlelo Hoʻākāka

Hoʻohana nui ʻia ka pepa epoxy 3240 ma ke ʻano he mea hoʻokaʻawale i nā lako electromechanical ma muli o kona mau waiwai mechanical a me ka uila kiʻekiʻe, ka haʻahaʻa o ka omo wai, ke 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 o nā mea hoʻokaʻawale ke hoʻololi i nā ʻano ʻino, a ke lilo nei ka pōʻino o nā kaha leaka i mea maopopo loa. No laila, he mea nui loa ka hoʻomohala ʻana i kahi papa epoxy me ke kūʻē ʻana i nā kaha 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.

2. Hoʻokolohua

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.

ii. Koho Pahu

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

ʻO ka manawa mālama o ka epoxy resin epoxy kūpaʻa i ka lumi lumi he 7 mau lā ma ke ana wela. Inā ʻoi aku ka nui o ka manawa mālama, hiki ke hoʻohana ʻia inā aia ka manawa gelation i loko o ka pae.

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 ℃.

E nānā i ka Papa 2 no nā papa kuhikuhi hana o prepreg

Nā waiwai o prepreg

c) Hoʻomākaukau i ka laminate lole aniani

  E ʻoki i ka prepreg i ka nui i makemake ʻia, e kau iā ia e like me nā koi kaʻina hana, e hoʻopaʻa i nā ʻaoʻao ʻelua me nā papa kila kila, e hoʻohana i ka mea hoʻokuʻu patented a i ʻole ke kiʻiʻoniʻoni o kā mākou hui e hoʻopau, pad pepa a me ka pā hao, a laila e hoʻouna aku i ka paʻi mua ʻia. E nānā i ka Papa 3 no nā kūlana hana kaomi

Kaʻina kaomi laminate

Ma hope o ke kaomi ʻana a hoʻoheheʻe ʻia e like me ke kaʻina hana i luna a hoʻomaha ʻia i lalo o 50 ℃, hiki ke loaʻa ka Epoxy Glass Sheet.

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.

Nā waiwai mechanical a me nā uila o ka Epoxy Glass Sheet me ke kū'ē'ē i nā kaha uila

c) Ka hopena o ke kaʻina hana ma luna o nā waiwai o nā laminates

ʻO ka hana o ka Epoxy Laminate Sheet e hilinaʻi mua ʻia i ka hana o ka matrix resin. Ma lalo o ka matrix resin a me nā mea hoʻoikaika i hoʻoholo ʻia, he mea nui ka mahana, ka manawa a me ke kaomi i ka hana o nā laminates. I ka hui pū ʻana me nā lako a me nā kūlana hana o ka hui, ua ʻimi ʻia a hōʻuluʻulu ʻia kahi hoʻonohonoho o nā ala hana kaomi no ka hana ʻana i nā laminates kiʻekiʻe, kahi e hana ai i nā palapala hana a hōʻoia i ke kūpaʻa o ka maikaʻi o ka huahana o nā kikoʻī like ʻole.

4. Panina

  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.
