ʻO ka paving asphalt emulsified i hana ʻia me nā emulsifier kiʻekiʻe e hoʻomaʻamaʻa i ke kūkulu ʻana ma ka pūnaewele.ʻAʻole pono e wela ka asphalt i kahi mahana kiʻekiʻe o 170 ~ 180 ° C ma mua o ka hoʻohana ʻana.ʻAʻole pono e hoʻomaloʻo ʻia nā mea minerale 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 ʻana o ka emulsion asphalt, hiki ke hoʻohele like ʻia ma ka ʻili o ka aggregate a loaʻa iā ia ka hoʻopili maikaʻi ʻana, no laila hiki iā ia ke mālama i ka nui o ka asphalt, hoʻomaʻamaʻa i nā kaʻina hana, hoʻomaikaʻi i nā kūlana kūkulu, a hoʻemi i ka pollution a puni. kaiapuni.Ma muli o kēia mau mea maikaʻi, ʻaʻole kūpono ka asphalt emulsified no ka paʻi ʻana i nā alanui, akā no ka pale ʻana i ka pali o ka hoʻopiha ʻana i nā embankments, ka wai ʻole o nā hale hale a me nā ana, ka anticorrosion o nā mea metala, ka hoʻomaikaʻi ʻana i ka ʻāina mahiʻai a me ke olakino mea kanu, ka moena holo o nā ala kaʻa, hoʻopaʻa one desert, etc. Hoʻohana nui ʻia ia i nā papahana he nui.No ka mea ʻaʻole hiki i ka emulsified asphalt ke hoʻomaikaʻi wale i ka ʻenehana hana o ka asphalt wela, akā e hoʻonui pū i ka laulā noi o ka asphalt, ua ulu wikiwiki ka emulsified asphalt.
ʻO ka emulsifier asphalt kekahi ʻano o ka surfactant.ʻO kona ʻano kemika he mau lipophilic a me hydrophilic pūʻulu.Hiki ke hoʻopili ʻia ma ke kikowaena ma waena o nā ʻāpana asphalt a me ka wai, a laila e hōʻemi nui i ka ikehu manuahi o ka pilina ma waena o ka asphalt a me ka wai, e lilo ia i surfactant e hana i kahi emulsion paʻa.
ʻO Surfactant kahi mea hiki ke hoʻohaʻahaʻa nui i ka ʻili o ka wai ke hoʻohui ʻia i kahi liʻiliʻi, a hiki ke hoʻololi nui i nā waiwai o ka interface a me ke kūlana o ka ʻōnaehana, no laila e hoʻohua ai i ka pulu, emulsification, ka huʻa, ka holoi ʻana, a me ka hoʻopuehu., antistatic, lubrication, solubilization a me nā ʻano hana e hoʻokō i nā koi o nā noi kūpono.
No ke ʻano o ke ʻano o ka surfactant, ua hoʻokumu mau ʻia kona mole me kahi ʻāpana kaulahao non-polar, hydrophobic a lipophilic hydrocarbon a me kahi hui polar, oleophobic a me hydrophilic.Aia kēia mau ʻāpana ʻelua ma ka ʻili.Hana ʻia nā ʻaoʻao ʻelua o ka molekele asymmetric.No laila, ʻike ʻia ka molecular structure o ka surfactant e kahi mole amphiphilic he lipophilic a me ka hydrophilic, a loaʻa iā ia ka hana o ka hoʻopili ʻana i ka ʻaila a me ka wai.
Ke ʻoi aku ka nui o nā surfactants i ka wai (ka micelle koʻikoʻi), hiki iā lākou ke hana i nā micelles ma o ka hopena hydrophobic.ʻOi aku ka nui o ka nui o ka emulsifier maikaʻi loa no ka asphalt emulsified ma mua o ka ʻike micelle koʻikoʻi.
