ʻO ka paving asphalt emulsified i hana ʻia me nā emulsifiers kiʻekiʻe e hoʻomaʻalahi i ke kūkulu ʻana ma kahi. ʻAʻohe pono e hoʻomehana i ka asphalt i kahi mahana kiʻekiʻe o 170 ~ 180 ° C ma mua o ka hoʻohana ʻana. ʻAʻole pono e hoʻomaloʻo a hoʻomehana ʻia nā mea mineral e like me ke one a me ka ʻiliʻili, hiki ke mālama i ka nui o ka wahie a me ka ikehu wela. . Ma muli o ka hana maikaʻi o ka emulsion asphalt, hiki ke hoʻolaha like ʻia ma luna o ka ʻili o ka aggregate a he pipili maikaʻi me ia, no laila hiki iā ia ke mālama i ka nui o ka asphalt, hoʻomaʻalahi i nā kaʻina hana kūkulu, hoʻomaikaʻi i nā kūlana kūkulu, a hoʻemi i ka haumia i ke kaiapuni a puni. Ma muli o kēia mau pono, ʻaʻole kūpono wale ka asphalt emulsified no ka paving alanui, akā no ka pale ʻana i ka pali o nā embankments hoʻopiha, ka pale ʻana i ka wai o nā hale a me nā ana, ka pale ʻana i ka ʻili o nā mea metala, ka hoʻomaikaʻi ʻana i ka lepo mahiʻai a me ke olakino o nā mea kanu, ka moena holoʻokoʻa o nā alahao, ka hoʻopaʻa ʻana i ke one wao nahele, a pēlā aku. Hoʻohana nui ʻia ia i nā papahana he nui. No ka mea, ʻaʻole hiki i ka asphalt emulsified ke hoʻomaikaʻi wale i ka ʻenehana kūkulu o ka asphalt wela, akā hoʻonui pū i ka laulā o ka noi o ka asphalt, ua ulu wikiwiki ka asphalt emulsified.

He ʻano surfactant ka emulsifier asphalt. ʻO kona ʻano kemika he mau hui lipophilic a me hydrophilic. Hiki ke hoʻopili ʻia ma ka pilina ma waena o nā ʻāpana asphalt a me ka wai, a laila e hōʻemi nui ana i ka ikehu manuahi o ka pilina ma waena o ka asphalt a me ka wai, e lilo ia i surfactant e hana ana i kahi emulsion like a paʻa.

ʻO ka Surfactant kahi mea hiki ke hoʻemi nui i ka ʻili o ka wai ke hoʻohui ʻia i kahi liʻiliʻi, a hiki ke hoʻololi nui i nā waiwai interface a me ke kūlana o ka ʻōnaehana, a laila e hana ana i ka pulu, emulsification, foaming, holoi, a me ka dispersion. , antistatic, lubrication, solubilization a me kahi moʻo o nā hana e hoʻokō ai i nā koi o nā noi hana.

ʻOiai ke ʻano o ka surfactant, ua haku mau ʻia kona molekala me kahi ʻāpana kaulahao hydrocarbon non-polar, hydrophobic a me lipophilic a me kahi hui polar, oleophobic a me hydrophilic. Aia pinepine kēia mau ʻāpana ʻelua ma ka ʻili. Hoʻokumu nā wēlau ʻelua o ka molekala mea hana i kahi ʻano asymmetric. No laila, ua hōʻike ʻia ke ʻano molekala o ka surfactant e kahi molekala amphiphilic he lipophilic a hydrophilic hoʻi, a he hana ia e hoʻopili ai i nā pae aila a me ka wai.

Ke ʻoi aku ka nui o nā surfactants ma mua o kahi ʻano i loko o ka wai (ka nui o nā micelle koʻikoʻi), hiki iā lākou ke hana i nā micelles ma o ka hopena hydrophobic. ʻOi aku ka nui o ka dosage emulsifier kūpono no ka asphalt emulsified ma mua o ka nui o nā micelle koʻikoʻi.
