ʻO ka mea hana kiʻiʻoniʻoni ka mea nui o ke aniani fiber infiltrant, ma ke ʻano he 2% a 15% o ka hapa nui o ka infiltrant formula, ʻo kāna kuleana ʻo ka hoʻopaʻa ʻana i ke aniani fiber i loko o nā pūpū, i ka hana ʻana o ka pale o nā fibers, i loaʻa i nā pūʻulu fiber ke kūlana maikaʻi o ka ʻoʻoleʻa, agglomeration, e hoʻokō i nā koi o nā huahana fiber. ʻO nā mea hana kiʻiʻoniʻoni maʻamau i hoʻohana ʻia i loko o ke aniani fiber infiltrant formulations he polymers, me ka epoxy resins, polyurethane, polyester, phenolic resins, modified polypropylene dispersions, a i ʻole emulsions. ʻO ka hana o nā mea hana kiʻiʻoniʻoni e hilinaʻi nui ʻia i ke ʻano molecular a me ke kaumaha molekala o ka polymer. No ka mea hana kiʻiʻoniʻoni like, ka ʻoʻoleʻa okīʻaha anianihiki ke hoʻoponopono ʻia e ke kaumaha mole o ka mea hana kiʻiʻoniʻoni, a ʻo kahi mea hana kiʻiʻoniʻoni me ke kaumaha mole kiʻekiʻe e ʻoi aku ka ʻoi aku o ka paʻakikī o ka fiber aniani, i kūpono no ka mālama ʻana ohoʻoikaika i nā huahana aniani ʻokiʻoki thermoplastic,ʻoiai he mea hana kiʻiʻoniʻoni me ka haʻahaʻa haʻahaʻa molekala kūpono no ka hanaʻana i nā wili i hoʻohanaʻia i ka wili a me ka hukiʻana. Loaʻa nā polymers epoxy resin aliphatic hydroxyl, ether, a me nā pūʻulu epoxy, a he ikaika kemika ma waena o nā hui polar i nā mea hana kiʻiʻoniʻoni epoxy, no laila ua loaʻa iā lākou ka hopena maikaʻi a me ka hoʻopili ʻana i nā fibers aniani;

Eia kekahi, hiki i ka hui epoxy i loko o ka epoxy film-forming agent ke hana me ka terminal hydroxyl group, terminal carboxyl group, terminal amino group, a me nā hui hana ʻē aʻe i ka ʻenekinia plastics e like me PBT, PET, PA, PC, etc. ʻO nā mea hana kiʻiʻoniʻoni polyester he nui nā pūʻulu ester, nā mea paʻa kemika unsaturated, a me nā hui hydrophilic i ke kaulahao nui, a hilinaʻi kā lākou hana i ke ʻano o ka waikawa a me ka waiʻona i hoʻohana ʻia i ka synthesis o ka polyester a me ka ratio. Ke hoʻoheheʻe ʻia ka resin base polyester resin, hiki i nā mea paʻa ʻelua unsaturated i loko o ka polyester film-forming agent ke polymerize a me ka hoʻopili ʻana me nā mea paʻa pālua i ka resin base e hana i kahi paʻa kemika ikaika a i ʻole entanglement kino, e hoʻomaikaʻi ai i ka ikaika paʻa interfacial. ʻO nā mea hana kiʻiʻoniʻoni polyester maʻamau ka maikaʻi o ka pulupulu a me nā waiwai komo a no laila ua hoʻohana ʻia e like me nā mea pulu i ka pultrusion, winding, spraying, chevron, a me nā huahana ʻē aʻe. ʻO ka polyurethane film-forming agent molecular chain ka hana hou ʻana i ka carbamate, ʻo ka noho ʻana o kēia mau pūʻulu polar e hana i ka polyurethane i ke aniani fiber i kahi paʻa maikaʻi loa, nā ʻāpana palupalu a paʻakikī o ka hui pū ʻana o ka elasticity kiʻekiʻe a me ke kūpaʻa abrasion, i ka manawa like, hiki ke hoʻopili ʻia ka polyurethane i ka hui isocyanate me ka mea hoʻopili matrix, hoʻomaikaʻi i ka mea hoʻopili matrix, hoʻomaikaʻi i ka hoʻopaʻa ʻana i ka matrix. ka hana ana omea hoohuihuihuahana.
