Emulsion bitumen imulsion nyowani inogadzirwa ne mechanical action ye asphalt uye emulsifier aqueous solution.
Emulsion bitumen inorongwa maererano neyakasiyana particle properties yebhitumeni emulsifier inoshandiswa: cationic emulsion bitumen, anionic emulsion bitumen uye nonionic emulsion bitumen.
Inopfuura 95% yekugadzirwa kwemigwagwa inoshandisa cationic emulsion bitumen. Sei cationic emulsion bitumen ine zvakanakira zvakadaro?
1. Kusarudzwa kwemvura kwakakura. Bhitumini, mvura uye bhitumini emulsifier ndizvo zvinhu zvikuru zve emulsion bitumen. Anionic emulsified bitumen inofanira kugadzirirwa nemvura yakapfava uye haigoni kuderedzwa nemvura yakaoma. Kune cationic emulsion bitumen, unogona kusarudza emulsion bitumen yemvura yakaoma. Iwe unogona kushandisa mvura yakaoma kugadzirira emulsifier aqueous solution, kana iwe unogona kuidzikisa zvakananga.
2. Kugadzirwa kuri nyore uye kugadzikana kwakanaka. Kugadzikana kweanions kwakashata uye zvakasanganiswa zvinoda kuwedzerwa kuti ive nechokwadi chekugadzikana kwechigadzirwa chakapedzwa. Muzviitiko zvakawanda, cationic emulsion bitumen inogona kuburitsa yakagadzikana emulsion bitument pasina kuwedzera zvimwe zvinowedzera.
3. Kune cationic emulsion bitumen, kune nzira dzakawanda dzekugadzirisa kukurumidza kwe demulsification uye mutengo wakaderera.
4. Cationic emulsified asphalt inogona kuramba ichivakwa semazuva ese mumwaka wemvura kana kuderera-kupisa (pamusoro pe5 ℃).
5. Kunamatira kwakanaka kune dombo. Cationic emulsion bitumen particles inotakura cationic charges. Kana ikasangana nedombo, asphalt particles inokurumidza kushambadzirwa pamusoro pebwe nekuda kwekukwezva kwezvinhu zvinopesana. Inoshandiswa mu micro surfacing uye slurry seal kuvaka.
6. The viscosity ye cationic emulsion bitumen iri nani pane iyo anionic emulsion bitumen. Paunenge uchipenda, cationic emulsion bhitumeni inonyanya kuoma, saka unogona kusarudza kuipfapfaidza. Pane zvinopesana, anionic emulsion bitumen iri nyore kupenda. Inogona kushandiswa semafuta anopinda mukati uye anonamira layer mafuta mukuvaka kudzivirira mvura uye kugadzira migwagwa.
7. Cationic emulsion bitumen inovhura kune traffic nekukurumidza.
