ʻO ka epoxy curing agent he mea kemika i hoʻohana ʻia e hoʻōlaepoxy resinsma ka hana kemika me nā pūʻulu epoxy i loko o ka resin epoxy e hana i kahi hale pili keʻa, no laila e hoʻolilo i ka resin epoxy i mea paʻa paʻa paʻa.
ʻO ka hana nui o ka epoxy curing agents ʻo ia ka hoʻonui ʻana i ka paʻakikī, ka pale ʻana i ka abrasion, a me ke kūpaʻa kemika o nā resins epoxy, e hana ana iā lākou i mea lōʻihi a paʻa, ʻo ia kahi ʻāpana o ka epoxy pultruded composites. Hōʻike kēia ʻatikala pehea e koho ai i ka epoxy-curing agent kūpono ma muli o nā kumu like ʻole:
E like me nā kūlana ho'ōla
- Ka ho'ōla ma ka lumi wela: Inā makemake ʻia ka hoʻōla wikiwiki ʻana ma ka lumi wela, hiki ke koho ʻia nā mea hoʻolaʻa amine aliphatic e like me ka ethylenediamine a me diethylenetriamine; inā ʻaʻole koi ʻia ka wikiwiki o ka mālama ʻana i ke kiʻekiʻe, a nānā i ka manawa hana, hiki ke koho ʻia nā mea hoʻolaʻa polyamide.
- Ka ho'ōla wela: No ka pale wela kiʻekiʻe a me nā waiwai mechanical, hiki ke hoʻohana ʻia nā mea hoʻolaʻa amine aromatic, e like me diaminodiphenylsulfone (DDS), etc.; no ka ho'ōla wikiwiki haʻahaʻa, hiki ke noʻonoʻo ʻia nā mea hoʻoponopono amine i hoʻololi ʻia me nā accelerators.
- Ka ho'ōla ma lalo o nā kūlana kūikawā: no ka ho'ōla ʻana i kahi wahi haʻahaʻa, hiki ke koho ʻia kahi mea hoʻōla hoʻōla pulu; no ka ʻōnaehana hoʻōla māmā, hiki ke koho ʻia ka lāʻau lapaʻau me ka photoinitiator a me ka epoxy acrylate.
E like me nā koi hana
- Nā waiwai mīkini: inā koi ʻia ka paʻakikī kiʻekiʻe a me ka ikaika kiʻekiʻe, hiki ke koho ʻia nā mea hoʻōla anhydride; inā makemake ʻia ka maʻalahi a me ka pale ʻana i ka hopena, ʻoi aku ka maikaʻi o nā mea hoʻōla paʻakikī e like me ka polysulfide rubber.
- Ke kū'ē kemika: nā koi kiʻekiʻe i ka waika, alkali, a me ke kūpaʻa pale,phenolic resinʻoi aku ka maikaʻi o ka lāʻau lapaʻau a i ʻole kekahi mea hoʻōla amine i hoʻololi ʻia.
- Ke kū'ē i ka wela: No nā wahi wela kiʻekiʻe, e like me luna o 200 ℃, hiki ke noʻonoʻo ʻia kahi mea hoʻōla silicone a i ʻole mea hoʻōla me kahi ʻano polyaromatic.
E like me ke kaiapuni hoʻohana
- Kaiapuni i loko: ʻoi aku ka maikaʻi o ka mālama ʻana i nā pono o ka mālama ʻana i ke kaiapuni, ʻoi aku ka maikaʻi o ka epoxy curing agent a i ʻole ka liʻiliʻi liʻiliʻi aliphatic amine curing agent.
- Kaiapuni waho: koi ʻia ke kū ʻana o ka wā maikaʻi, ʻoi aku ka maikaʻi o nā alicyclic amine curing agents me ka pale UV maikaʻi.
- Nā kaiapuni kūikawā: Ma nā wahi me nā koi hoʻomaʻemaʻe kiʻekiʻe e like me ka meaʻai a me ka lāʻau lapaʻau, pono e koho ʻia nā mea hoʻōla epoxy non-toxic a haʻahaʻa haʻahaʻa e like me ka palekana meaʻai polyamide curing agents.
E noʻonoʻo i nā koi kaʻina hana
- Ka manawa hana: No ka lōʻihi o ka hana ʻana, e koho i kahi lāʻau lapaʻau latent, e like me ka dicyandiamide, a pēlā aku.
- No ka ho'ōla ho'ōla ʻana: No ka hoʻōla ʻana i ka waihoʻoluʻu ʻole a me ka akaka, koho i nā mea ho'ōla amine alicyclic, a pēlā aku.
Hoʻohuiʻia me ke kumu kūʻai
- Ma lalo o ke kumu o ka hoʻokō ʻana i nā koi o ka hana, e hoʻohālikelike i ke kumukūʻai a me ke ʻano o nā lāʻau lapaʻau like ʻole. ʻO ke kumu kūʻai o nā mea ho'ōla amine maʻamau he haʻahaʻa, ʻoiai ʻoi aku ka pipiʻi o kekahi mau mea lapaʻau hana kūikawā e like me ka fluorine-containing a me ka silicone-containing agents.
Ka manawa hoʻouna: Mar-18-2025
