Emulsion phula ndi emulsion yatsopano yopangidwa ndi mawotchi a asphalt ndi emulsifier amadzimadzi njira.
Phula la emulsion limagawidwa malinga ndi mitundu yosiyanasiyana ya phula la emulsifier yogwiritsidwa ntchito: phula la cationic emulsion, phula la anionic emulsion ndi phula la nonionic emulsion.
Oposa 95% ya zomangamanga msewu amagwiritsa cationic emulsion phula. N'chifukwa chiyani phula la cationic emulsion lili ndi ubwino wotere?
1. Kusankhidwa kwa madzi ndi kwakukulu. Bitumeni, madzi ndi phula emulsifier ndi zipangizo zazikulu za emulsion phula. phula la anionic emulsified liyenera kukonzedwa ndi madzi ofewa ndipo silingathe kuchepetsedwa ndi madzi olimba. Pakuti cationic emulsion phula, mukhoza kusankha emulsion phula kwa madzi olimba. Mutha kugwiritsa ntchito madzi olimba kuti mupange emulsifier amadzimadzi yankho, kapena mutha kutsitsa mwachindunji.
2. Kupanga kosavuta ndi kukhazikika kwabwino. Kukhazikika kwa anions ndikosauka ndipo zosakaniza ziyenera kuwonjezeredwa kuti zitsimikizire kukhazikika kwazinthu zomalizidwa. Nthawi zambiri, cationic emulsion phula akhoza kupanga khola emulsion phula popanda kuwonjezera zina.
3. Pakuti cationic emulsion phula, pali njira zambiri kusintha demulsification liwiro ndi mtengo wotsika.
4. Asphalt ya cationic emulsified imatha kupangidwabe monga mwanthawi zonse munyengo yachinyezi kapena yotentha (pamwamba pa 5 ℃).
5. Kumamatira bwino mwala. cationic emulsion phula phula particles kunyamula cationic milandu. Mukakumana ndi mwala, tinthu tating'onoting'ono ta asphalt timakopeka mwachangu pamwamba pamwala chifukwa chokopa zinthu zotsutsana. Amagwiritsidwa ntchito popanga ma microsurfacing ndi slurry seal.
6. Kukhuthala kwa phula la cationic emulsion ndikwabwino kuposa phula la anionic emulsion. Pamene kujambula, cationic emulsion phula ndi zovuta, kotero inu mukhoza kusankha kupopera. M'malo mwake, phula la anionic emulsion ndilosavuta kujambula. Itha kugwiritsidwa ntchito ngati mafuta olowera osanjikiza ndi mafuta osanjikiza pomanga pomanga kutsekereza madzi ndi kukonza misewu.
7. Bitumen ya cationic emulsion imatsegulira magalimoto mwachangu.
