ʻO ka bitumen emulsion he emulsion hou i hana ʻia e ka hana mechanical o ka asphalt a me ka emulsifier aqueous solution.
Hoʻokaʻawale ʻia ka bitumen emulsion e like me nā ʻāpana ʻokoʻa o ka bitumen emulsifier i hoʻohana ʻia: cationic emulsion bitumen, anionic emulsion bitumen a me ka nonionic emulsion bitumen.
ʻOi aku ma mua o 95% o ka hana alanui e hoʻohana ana i ka bitumen emulsion cationic. No ke aha i loaʻa ai i ka cationic emulsion bitumen nā mea maikaʻi?
1. He ākea ka koho wai. ʻO ka bitumen, ka wai a me ka bitumen emulsifier ka mea nui no ka bitumen emulsion. Pono e hoʻomākaukau ʻia ka bitumen emulsified anionic me ka wai palupalu a ʻaʻole hiki ke hoʻoheheʻe ʻia me ka wai paʻakikī. No ka cationic emulsion bitumen, hiki iā ʻoe ke koho i ka bitumen emulsion no ka wai paʻakikī. Hiki iā ʻoe ke hoʻohana i ka wai paʻakikī no ka hoʻomākaukau ʻana i kahi solution aqueous emulsifier, a i ʻole hiki iā ʻoe ke hoʻoheheʻe pololei iā ia.
2. Hana maʻalahi a paʻa maikaʻi. He ʻilihune ka paʻa o nā anion a pono e hoʻohui ʻia nā admixtures e hōʻoia i ka paʻa o ka huahana i hoʻopau ʻia. I nā manawa he nui, hiki i ka cationic emulsion bitumen ke hana i ka bitument emulsion paʻa me ka hoʻohui ʻole i nā mea hoʻohui ʻē aʻe.
3. No ka bitumen cationic emulsion, nui nā ala e hoʻoponopono ai i ka wikiwiki demulsification a ua haʻahaʻa ke kumukūʻai.
4. Hiki ke hana 'ia ka asphalt emulsified cationic e like me ka mea mau i nā kau ha'aha'a a ha'aha'a paha (ma luna o 5℃).
5. Pili maikaʻi i ka pōhaku. Lawe nā ʻāpana bitumen cationic emulsion i nā koina cationic. Ke hoʻopili ʻia me ka pōhaku, hoʻopili koke ʻia nā ʻāpana asphalt ma luna o ka ʻili o ka pōhaku ma muli o ka huki ʻana o nā waiwai kūʻē. Hoʻohana ʻia i ka micro surfacing a me ka slurry seal construction.
6. 'Oi ka viscosity o ka bitumen emulsion cationic ma mua o ka bitumen emulsion anionic. I ka pena ʻana, ʻoi aku ka paʻakikī o ka cationic emulsion bitumen, no laila hiki iā ʻoe ke koho e pīpī iā ia. ʻO ka mea ʻē aʻe, maʻalahi ke pena ʻana i ka bitumen emulsion anionic. Hiki ke hoʻohana ʻia ma ke ʻano he ʻaila paʻa paʻa a me ka ʻaila paʻa paʻa i ke kūkulu ʻana i ka wai a me ka paving alanui.
7. Wehe koke ka bitumen emulsion cationic i ke kaʻa.
