2023-10-11

  ʻO ka wai epoxy resin he ʻano polymer me kahi ʻano molekala o (C11H12O3)n, e pili ana i ka huaʻōlelo maʻamau no nā polymers i loaʻa ʻelua mau pūʻulu epoxy i loko o kā lākou mau mole. He resin thermosetting ka huahana condensation o epichlorohydrin a me bisphenol A a i ʻole polyols. Ma muli o ka hana kemika o ka hui epoxy, hiki ke wehe ʻia e nā pūhui like ʻole i loaʻa i ka hydrogen ikaika, hoʻōla ʻia, a hoʻopaʻa ʻia e hana i kahi ʻōnaehana pūnaewele, e hoʻolilo iā ia i resin thermosetting. ʻO ka Bisphenol A epoxy resin ʻaʻole wale ka nui o ka hana nui a me nā ʻano ʻokoʻa piha loa, akā ke hoʻomau nei hoʻi i ka hoʻonui ʻana i nā ʻano hou i hoʻololi ʻia me ka hoʻomaikaʻi ʻana i ka maikaʻi.

 

  ʻO ka maikaʻi o ke kino, mechanical, a me ka uila insulation waiwai o ka epoxy resin, kona mau mea hoʻopili i nā mea like ʻole, a me ka maʻalahi o kāna ʻenehana hana ʻana ʻaʻole i hoʻohālikelike ʻia e nā plastic thermosetting ʻē aʻe. No laila, hoʻohana nui ʻia ia ma nā ʻano ʻano like ʻole o ka hoʻokele waiwai o ka ʻāina e like me nā uhi, nā mea hoʻohuihui, nā mea hoʻolei, nā mea hoʻopili, nā mea hoʻoheheʻe, a me nā mea hoʻoheheʻe injection.


Waiwai Epoxy Resin

 

  ʻO ka wai epoxy resin ua hoʻohana nui ʻia i nā kula e like me nā adhesives, coatings, composite material, electronics, and motors, a he ʻekolu mau pono nui:

 

  1. Epoxy resin i haʻahaʻa curing shrinkage a me ka maikai dimensional paʻa.


  2. Loaʻa i ka epoxy resin nā waiwai kemika paʻa a ʻaʻole hiki ke ʻino ʻia a ʻeha paha e nā waikawa maʻamau, alkalis, kemika, a me nā mea hoʻoheheʻe ʻoihana.


  3. He hoʻopili maikaʻi loa ka epoxy resin i nā mea he nui, ka ikaika mechanical kiʻekiʻe, a hiki ke kū i ke koʻikoʻi o ke kaiapuni lōʻihi, e hilinaʻi nui ʻia.

 

  ʻO ka ʻoiaʻiʻo, ʻo ka pōmaikaʻi nui loa o ka epoxy resin ʻo ia ka loli. Ma ka hoʻololi ʻana i ke ʻano haku mele, hiki iā ia ke hoʻōla a hoʻomau ʻole ʻia no ka manawa lōʻihi. Hiki ke hoʻololi ʻia i nā mea hoʻopili paʻa a i ʻole nā ​​mea hiki ke maʻalahi.

 

Nā ʻano no ka hoʻoikaika a me ka hoʻololi ʻana i ka resin epoxy:

  

  ʻO ka epoxy resin (EP) kahi resin thermosetting koʻikoʻi, i hana ʻia e ka hopena o nā EP oligomers a me nā mea hoʻōla. Hoʻokaʻawale ʻia i ʻelima mau ʻāpana e like me ke ʻano kemika a me ke ʻano hoʻopaʻa ʻana o ka waihona EP: aliphatic amine, aliphatic ester, aliphatic ether, aliphatic cyclic, a me nā mea hoʻohui epoxy cyclic aromatic.

 

  Ma muli o ka nui o nā pūʻulu EP i ka EP maʻemaʻe, ke kiʻekiʻe kiʻekiʻe o ka hoʻopili ʻana i ke keʻa o ka hale i hoʻōla ʻia, ka haʻahaʻa haʻahaʻa o nā kaulahao molekala, a me ke koʻikoʻi o loko, ʻoi aku ka brittleness o ka mea EP i hoʻōla ʻia, maikaʻi ʻole ka hopena a me ka lōʻihi o ka luhi. ka mea e kaupalena ana i kāna noi a me ka hoʻomohala ʻana i kekahi mau ʻenehana kiʻekiʻe me nā koi kiʻekiʻe no ka lōʻihi a me ka hilinaʻi. No laila, pono e hoʻoikaika a hoʻololi i ka EP me ka mālama ʻana i kāna mau waiwai maikaʻi.


Waiwai Epoxy Resin

 

  I kēia manawa, ʻekolu mau ala nui e hoʻoikaika a hoʻololi i ka EP ma ka ʻoihana:

 

  (1) Hoʻohui i nā elastomers rubber, core-shell polymers, thermoplastic resins (TP), thermotropic liquid crystal polymers (TLCP), a me nā nano-particles i ka EP matrix e hana i ka micro-phase separation a i ʻole ka ʻano homogeneous;

 

  (2) E hoʻopaʻa mau i ka TP ma ka EP ʻekolu-dimensional cross-linking network e hana i kahi ʻano pūnaewele interpenetrating no ka paʻakikī;

  

   (3) Hoʻoponopono i ka microstructure o EP, e like me ka hoʻokomo ʻana i nā ʻāpana kaulahao ʻoi aku ka maʻalahi i ka ʻoihana cross-linking ʻekolu-dimensional e hoʻomaikaʻi i kona molecular flexibility, a i ʻole ka hoʻokomo ʻana i kahi ʻano hoʻokaʻawale micro-phase e hoʻomaikaʻi i ka synergy deformation o nā ʻāpana kaulahao mole, e loaʻa ana. paʻakikī.

 

Ka hoʻohana ʻana i ka Epoxy Resin i nā uhi

 

  Loaʻa i ka Epoxy resin ka hapa nui o nā noi i nā uhi, a hiki ke hana ʻia i nā ʻano like ʻole me nā hiʻohiʻona ʻokoʻa a me nā hoʻohana. ʻO kāna mau hiʻohiʻona maʻamau, ʻo ia hoʻi: (1) maikaʻi ke kūpaʻa kemika, ʻoi aku ka pale alkali; (2) pili ikaika i ka pena kiʻiʻoniʻoni, ʻoi aku hoʻi i ka metala; (3) maikaʻi ka wela a me ka uila insulation waiwai; (4) paʻa kala maikaʻi o ke kiʻi pena.


  Eia nō naʻe, ʻaʻole maikaʻi ka pale ʻana i ka wā o ka bisphenol A type epoxy resin coatings, a ʻoi aku ka maikaʻi o ke kiʻi pena i ka chalking a nalowale kona ʻōlinolino i waho, no laila ʻaʻole kūpono ia no ka hoʻohana ʻana i waho a me nā uhi hoʻonaninani kiʻekiʻe. No laila, hoʻohana nui ʻia nā uhi epoxy resin e like me nā pena anticorrosive, metala primers, a me nā pena insulating, akā hiki ke hoʻohana ʻia nā uhi i hana ʻia me ka heterocyclic a me aliphatic epoxy resins no nā noi waho.
