Thepa ea asphalt ea emulsified e lebisa tlhokomelo e khethehileng ts'ebetsong e qaqileng ea ts'ebetso
Ho na le mefuta e 'meli e meholo ea mekhoa ea ho fetola lisebelisoa tsa asphalt emulsified: mokhoa oa ho kopanya ka ntle le mokhoa oa ho kopanya ka hare. Mokhoa oa ho kopanya o ka ntle ke oa ho qala ka ho etsa lisebelisoa tsa motheo tsa asphalt tse entsoeng ka emulsified, ebe o eketsa mofetoleli oa latex oa polymer ho thepa ea motheo ea asphalt e entsoeng ka emulsified, ebe o kopanya le ho hlohlelletsa ho e etsa. Hangata emulsion ea polymer e hlaha e le CR emulsion, SBR emulsion e amanang le acrylic emulsion, joalo-joalo Mokhoa oa ho kopanya ka hare ke ho qala ho kopanya rabara, polasetiki le li-polymer tse ling le lisebelisoa tse ling ka har'a asphalt e mebala e chesang. Kamora ho kopanya ka mokhoa o ts'oanang le ho fumana karabelo e felletseng lipakeng tsa polymer le asphalt e mebala, ho fumanoa asphalt e fetotsoeng ea polymer. Mohato o latelang ke ho Modified asphalt emulsion e entsoe ka bonono ba emulsification, 'me polymer e atisang ho sebelisoa ka mokhoa oa ho kopanya ka hare ke SBS. Haeba thepa ea asphalt e mebala e emisoa hora ka mor'a ho kopanya, hloekisa bokaholimo ba moqomo o kopanyang, eketsa metsi a hloekileng, 'me u hloekise seretse. Ka mor'a moo, tlosa metsi, ho etsa bonnete ba hore ha ho na ho bokella metsi ka nkhong ho thibela liphetoho ho risepe kapa esita le mafome ts'ebetsong ea ts'ebetso e kang websaeteng. Nakong ea ts'ebetso, motho e mong le e mong o tseba ho ela hloko ka ho khethehileng mekhoa e mengata e nyenyane ea ts'ebetso ho qoba tahlehelo e sa hlokahaleng mesebetsing ea bona.
Ts'ebetso ea ts'ebetso ea lisebelisoa tsa asphalt tsa emulsified:
Tšenyo ea tsitsipano e kaholimo ea lisebelisoa tsa asphalt le metsi li fapane haholo, 'me ha li kopane habonolo ka mocheso o tloaelehileng kapa o phahameng. Ha lisebelisoa tsa asphalt tse entsoeng ka emulsified li etsa ts'ebetso ea mochini joalo ka centrifugation, cutting, and impact, the emulsified asphalt equipment e fetoha likaroloana tse nang le karoloana ea 0.1 ~ 5 μm, 'me e ajoa ka metsing a nang le surfactant (emulsifier-stabilizer) , emulsifier e ka khabisoa ka tsela ea tataiso holim'a likaroloana tsa thepa ea asphalt e mebala-bala, kahoo e fokotsa tsitsipano pakeng tsa metsi le sekontiri se mebala-bala, e leng se lumellang likaroloana tsa asphalt tse mebala-bala hore li thehe mokhoa o thabisang oa ho aba ka metsing. Thepa ea asphalt ea emulsified le lisebelisoa li na le oli ka metsing. ka emulsion. Mofuta ona oa tsamaiso o sootho, 'me o na le asphalt e mebala e le karolo e qhalakaneng le metsi e le mohato o tsoelang pele,' me o natefeloa ke metsi a mangata mochesong oa kamore. Lisebelisoa le lisebelisoa tsa asphalt tse entsoeng ka emulsified Ka tsela e itseng, lisebelisoa tsa asphalt tse entsoeng ka emulsified le lisebelisoa li sebelisa metsi ho "koba" sekontiri se mebala-bala, kahoo se laola ho phalla ha sekontiri se mebala-bala.
Thepa ea asphalt e entsoeng ka emulsified e qhibilihisa asphalt ea 'mala oa mantlha' me e abela ka bo eona likaroloana tse nyane tsa 'mala oa asphalt ka tharollo e nang le metsi e nang le emulsifier ho etsa sekontiri sa' mala oa sekontiri. Seretse sa samente se entsoeng ka sekontiri se entsoeng ka sekontiri se sebelisoang kahong ea pina ea slab se sebelisa lisebelisoa tsa asphalt tsa cationic emulsified. Sepheo ke ho lokisa elasticity, toughness le durability samente emulsified asphalt thepa seretse. Hangata li-polymers li sebelisoa ho fetola asphalt.
