Introduction

I koʻu ʻimi ʻana i ka ʻimi ʻana o Nā Pepa Epoxy Resin, ua ʻike ʻia he mea koʻikoʻi ka hoʻomaopopo ʻana i ko lākou ʻano pale wela. Ma kēia ʻatikala, e wehewehe wau i nā waiwai pale wela o nā lau, e ʻimi ana i ko lākou koʻikoʻi ma nā ʻano noi a me nā ʻoihana.

Pepa Resin Epoxy

ʻO ka wehewehe pōkole o nā Pepa a me kā lākou hoʻohana ʻana

ʻO nā pepa, i haku ʻia me ka epoxy resin a me nā mea hoʻoikaika, hoʻohana nui ʻia i nā ʻoihana like ʻole. ʻO kā lākou versatility he mea nui ia i nā noi mai ke kūkulu ʻana a hiki i ka uila. Hāʻawi kēia mau pepa i ka ikaika mechanical, insulation uila, a me ka pale kemika, e hoʻolilo iā lākou i kūpono no nā kumu he nui.

ʻO ke koʻikoʻi o ka pale ʻana i ka wela ma nā noi like ʻole ʻo ke kūpaʻa wela kahi helu kumu i ka hoʻokō ʻana a me ke ola o nā mea waiwai, ʻoi aku hoʻi i nā noi i wehe ʻole ʻia i nā wela kupaianaha. Ma nā ʻoihana e like me ka mokulele, kaʻa, a me nā lako, pono nā mea waiwai e kū i nā wela kiʻekiʻe me ka ʻole o ka hoʻololi ʻana i kā lākou hoʻoholo kōkua a i ʻole pono. Epoxy tar sheets, ma hope iho, pono e loaʻa i nā waiwai pale wela e hoʻokō i nā noi o kēia mau noi.

 

He aha ka Epoxy Resin?

ʻO ka epoxy tar kahi polymer thermosetting i ʻike ʻia mai ka pane ma waena o ka epichlorohydrin a me ka bisphenol-A. Hāʻawi kēia lole maʻalahi i ka hoʻopili maikaʻi ʻana, nā waiwai mechanical, a me ke kūpaʻa kemika, e kūpono ana i nā noi like ʻole. Hoʻohana maʻamau ʻia e like me ke ʻano o nā mea i hoʻohui ʻia, hāʻawi ka epoxy tar i ke kākoʻo kumu a me ka palekana i nā kumu kūlohelohe. ʻO ka wehewehe a me ka hoʻohui ʻia ʻana o nā pā epoxy tar, nā filament fortification (e like me fiberglass a i ʻole carbon fiber), a me nā mea i hoʻohui ʻia. Hāʻawi ka lattice gum i ke ʻano koʻikoʻi, ʻoiai nā mea kākoʻo e hoʻomaikaʻi i nā waiwai mechanical e like me ka maikaʻi a me ka paʻa. Hiki i nā mea i hoʻohui ʻia ke hoʻohui i nā mea hoʻopihapiha, nā mea pale ahi, a i ʻole nā ​​​​mea hana hoʻōla, ma muli o nā waiwai i makemake ʻia o ka mea hope.

 

Nā noi maʻamau i nā ʻoihana e like me ke kūkulu ʻana, ka uila, a me ka Aerospace

Ke kūkulu ʻana: Ma ke ʻano o nā ʻāpana kūkulu, nā mea hoʻopili, a me nā uhi no nā hale, nā alahaka, a me nā ʻoihana.

Electronics: No nā papa kaapuni i paʻi ʻia (PCBs), hoʻopili ʻia o nā mea uila, a me ka pale uila.

Aerospace: Ma nā ʻāpana mokulele, e like me nā panela fuselage, nā ʻēheu, a me nā hale o loko, kahi e pono ai ka māmā a me ka ikaika kiʻekiʻe.

 

ʻO ka nānā ʻana i nā ʻano mea kūʻai wela

ʻO nā lau epoxy resin hōʻike i ke kūpaʻa mahana kupaianaha, e ʻae iā lākou e kū i kahi ākea ākea me ka ʻole o ka hōʻino nui ʻana. He mea nui kēia waiwai no ka mālama ʻana i ka pono o ke kūkulu ʻana a me ka hana ma nā wahi wela kiʻekiʻe.

Nā mea e hoʻopili ai i ka pale wela

Hoʻohui Kemika: ʻO ke ʻano kemika o ka resin epoxy a me nā mea hoʻohui e hoʻoikaika i kona kūpaʻa wela a me ke kū ʻana i ka wela.

Kaʻina Hoʻolaʻa: He mea koʻikoʻi ka hoʻōla kūpono, me ka mahana a me ka lōʻihi, no ka loaʻa ʻana o ka pale wela kiʻekiʻe.

Hoʻoikaika: ʻO ke ʻano a me ke ʻano o nā fibers hoʻoikaika e pili ana i nā waiwai wela o nā lau.

 

Hoʻohālikelike me nā ʻano resins ʻē aʻe

Ke hoʻohālikelike ʻia me nā ʻano resins ʻē aʻe, e like me ka polyester a i ʻole vinyl ester, hāʻawi ka epoxy resin i ke kūpaʻa ʻoi aku ka maikaʻi o ka mahana a me ke kūpaʻa dimensional. ʻO kona hiki ke mālama i nā waiwai mechanical i nā mahana kiʻekiʻe e hoʻokaʻawale iā ia ma ke ʻano he koho makemake i nā noi koi.

 

Hoʻohui Kimia o Epoxy Resin

He kuleana koʻikoʻi ka haku mele ʻana o ka epoxy resin i ka hoʻoholo ʻana i kona kūpaʻa wela. ʻO nā resine epoxy me nā apo ʻala i loko o kā lākou ʻano molekala e hōʻike i ke kūpaʻa wela kiʻekiʻe ke hoʻohālikelike ʻia me nā resins epoxy aliphatic. Hoʻohui ʻia, hiki i ka hele ʻana o nā mea hoʻohui e like me nā stabilizers wela a i ʻole nā ​​​​pale ahi e hiki ke hoʻonui i ka pale wela o nā lau.

 

Ke Kaʻina Hana Hoʻōla a me ka Hoʻopaʻa Hoʻohui Kea

ʻO ke kaʻina hana hoʻōla o ka epoxy resin e pili ana i ka hopena kemika ma waena o ka resin a me ka lāʻau lapaʻau, e hana ana i kahi pūnaewele pili kea. He mea koʻikoʻi ka mana kūpono o ka mālama ʻana i ka mahana a me ka lōʻihi no ka loaʻa ʻana o ka nui o ka hoʻopaʻa ʻana i ke keʻa, e pili pono ana i ka pale wela o ka huahana hope. ʻO ka lawa ʻole o ka hoʻōla ʻana hiki ke hopena i ka haʻahaʻa haʻahaʻa haʻahaʻa a me ka emi ʻana o nā waiwai mechanical.

 

Hoʻoikaika a me nā mea hoʻohui

ʻO ka hoʻohui ʻia ʻana o nā fibers hoʻoikaika, e like me ka fiberglass a i ʻole ka carbon fiber, e hoʻonui i nā waiwai mechanical o nā lau a kōkua i ko lākou pale ʻana i ka wela. Hāʻawi kēia mau mea hoʻoikaika i ke kaumaha a hāʻawi i ka ikaika hou i nā mahana kiʻekiʻe. Eia kekahi, hiki i nā mea hoʻohui e like me nā mea hoʻopiha wela a i ʻole nā ​​​​mea hoʻoikaika paʻakikī ke hoʻomaikaʻi hou i ke kūpaʻa wela a me ka lōʻihi o nā composites epoxy resin.

 

ʻO ke aniani hoʻololi wela (Tg) a me kona ʻano nui

ʻO ka mahana hoʻololi aniani (Tg) kahi ʻāpana koʻikoʻi e hōʻike ana i ka hoʻololi ʻana mai kahi aniani a i kahi kūlana rubbery i ka resin epoxy. Hōʻike maʻamau nā pepa i kahi Tg mai 50°C a i 200°C, ma muli o ke ʻano hana a me nā kūlana hoʻōla. Hōʻike ka Tg kiʻekiʻe i ke kūpaʻa mahana ʻoi aku ka maikaʻi, no ka mea, paʻa mau ka mea i nā wela kiʻekiʻe, e hōʻemi ana i nā loli a me ka deformation.

 

ʻO ka wela hoʻoneʻe wela (HDT)

ʻO ka wela wela (HDT) ʻo ia ka mahana i hoʻoheheʻe ʻia kahi mea ma lalo o kahi haʻawe i kuhikuhi ʻia. Hōʻike nā pepa i nā waiwai HDT mai 100°C a 300°C, e kūpono ana ia mau mea no nā noi i ʻike ʻia i nā wela haʻahaʻa a kiʻekiʻe. Hiki i nā mea hoʻoikaika e like me ka carbon fiber ke hoʻonui nui i ka HDT o nā composites epoxy resin, e hoʻonui ana i kā lākou pono i ke koi ʻana i nā wahi wela.

 

Coefficient o ka Hoonui Thermal (CTE)

ʻO ka coefficient of thermal expansion (CTE) e ana i ka hoʻololi ʻana i ka nui o kahi mea me ka hoʻololi ʻana o ka mahana. Hōʻike pinepine nā pepa Epoxy i nā waiwai CTE haʻahaʻa, e hōʻike ana i nā loli liʻiliʻi liʻiliʻi ma luna o kahi ākea ākea. Pono kēia waiwai no ka mālama ʻana i ke kūpaʻa dimensional a me ka pale ʻana i ka warping a i ʻole distortion i nā noi wela kiʻekiʻe.

 

Nā noi o nā Pepa i nā Kaiapuni Kūlana Kiʻekiʻe

Aerospace a me nā ʻāpana mokulele: I ka ʻoihana aerospace, hoʻohana nui ʻia nā pepa i ka hana ʻana i nā ʻāpana mokulele i hoʻopaʻa ʻia i nā wela wela i ka wā lele. Aia kēia mau ʻāpana i nā panela fuselage, nā ʻēheu, ka ʻili o ka huelo, a me nā hale o loko. Hāʻawi ka Epoxy resin composites i ke kaulike o ka māmā, ka ikaika kiʻekiʻe, a me ka pale wela, e hāʻawi ana i ka hana holoʻokoʻa a me ka palekana o ka mokulele.

Nā ʻāpana kaʻa: Ma ka ʻāpana kaʻa, he kuleana koʻikoʻi nā pepa i ka hana ʻana i nā ʻāpana like ʻole i ʻike ʻia i ka wela o ka mīkini, friction, a me nā mea kūlohelohe. Aia kēia mau ʻāpana i nā paneli kino, nā uhi ʻenekini, nā intake manifold, a me nā ʻōnaehana brake. Hāʻawi ka Epoxy resin composites i ka pale wela maikaʻi loa, ka pale ʻana i ka corrosion, a me ke kūpaʻa dimensional, e hoʻonui i ka hilinaʻi a me ka lōʻihi o nā ʻāpana kaʻa.

ʻEleke a me ka uila uila: I loko o nā noi uila, lilo nā pepa i mea hoʻolalelale no nā papa kaapuni paʻi (PCB), nā pā uila, a me nā mea semiconductor. Hāʻawi kēia mau mea i ka insulation thermal, conductivity uila, a me ka pale ʻana i ka makū a me nā mea haumia kaiapuni. Hāʻawi ka Epoxy resin composites i ka pale wela ʻoi aku ka maikaʻi, e hōʻoiaʻiʻo ana i ka hana pono o nā ʻōnaehana uila i ke koi ʻana i nā kaiapuni wela.

 

Nā ʻano hoʻāʻo no ka pale ʻana i ka wela: nā maʻamau o ka ASTM no nā palapala hoʻāʻo

Hoʻokumu ka American Society for Testing and Materials (ASTM) i nā kaʻina hana maʻamau no ka loiloi ʻana i nā waiwai pale wela o nā lau. Aia kēia mau maʻamau i ka ASTM D648 no ka wela wela (HDT), ʻo ASTM E831 no ka mahana hoʻololi aniani (Tg), a me ka ASTM E228 no ka coefficient of thermal expansion (CTE).
