QXME 103P; ʻO ka mea hoʻoheheʻe asphalt, Hydrogenated Tallow Amine, Stearyl Amine

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 o ka emulsion asphalt, hiki ke hoʻohele like ʻia ma ka ʻili o ka aggregate a loaʻa ka hoʻopili maikaʻi me ia, 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 i ke kaiapuni a puni. Ma muli o kēia mau pōmaikaʻi, ʻaʻole kūpono wale ka asphalt emulsified no ka paving alanui, akā no ka pale ʻana i ka pali o ka hoʻopiha ʻana i nā embankments, waterproofing o nā hale hale a me nā ana, anticorrosion ili o nā mea metala, ka hoʻomaikaʻi ʻana i ka lepo a me ke olakino mea kanu, ka moena holoʻokoʻa holoʻokoʻa o nā ala kaʻa, ke one one fixation, etc. 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 polar, oleophobic a me ka hui hydrophilic. Aia kēia mau ʻāpana ʻelua ma ka ʻili. Hana ʻia nā ʻaoʻao ʻelua o ka molekele asymmetric. No laila, ʻike ʻia ke ʻano mole 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 (koʻikoʻi micelle concentration), 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.
