Emulsion bitumen jẹ emulsion tuntun ti a ṣẹda nipasẹ iṣe adaṣe ti idapọmọra ati ojutu olomi emulsifier.
Emulsion bitumen ti wa ni tito lẹšẹšẹ ni ibamu si awọn ti o yatọ patiku-ini ti bitumen emulsifier ti a lo: cationic emulsion bitumen, anionic emulsion bitumen ati nonionic emulsion bitumen.
Diẹ sii ju 95% ti ikole opopona nlo bitumen emulsion cationic. Kini idi ti bitumen emulsion cationic ni iru awọn anfani bẹẹ?
1. Awọn omi selectivity jẹ jo jakejado. Bitumen, omi ati emulsifier bitumen jẹ awọn ohun elo akọkọ fun bitumen emulsion. Bitumen emulsified Anionic gbọdọ wa ni ipese pẹlu omi rirọ ati pe a ko le fomi pẹlu omi lile. Fun bitumen emulsion cationic, o le yan bitumen emulsion fun omi lile. O le lo omi lile lati ṣeto ojutu olomi emulsifier, tabi o le ṣe dilute taara.
2. Iṣelọpọ ti o rọrun ati iduroṣinṣin to dara. Iduroṣinṣin ti anions ko dara ati awọn admixtures nilo lati fi kun lati rii daju pe iduroṣinṣin ti ọja ti pari. Ni ọpọlọpọ igba, bitumen emulsion cationic le ṣe agbejade bitument emulsion iduroṣinṣin laisi fifi awọn afikun miiran kun.
3. Fun bitumen cationic emulsion, awọn ọna pupọ wa lati ṣatunṣe iyara demulsification ati iye owo jẹ kekere.
4. Cationic emulsified idapọmọra le tun ti wa ni ti won ko bi ibùgbé ni ọriniinitutu tabi kekere-otutu akoko (loke 5 ℃).
5. Adhesion ti o dara si okuta. Awọn patikulu bitumen Cationic emulsion gbe awọn idiyele cationic. Nigbati o ba wa ni ifọwọkan pẹlu okuta, awọn patikulu idapọmọra ti wa ni kiakia ni ipolowo lori oke ti okuta nitori ifamọra ti awọn ohun-ini idakeji. Lo ninu bulọọgi surfacing ati slurry asiwaju ikole.
6. Awọn iki ti cationic emulsion bitumen dara ju ti anionic emulsion bitumen. Nigbati kikun, cationic emulsion bitumen jẹ nira sii, nitorinaa o le yan lati fun sokiri rẹ. Ni ilodi si, bitumen emulsion anionic jẹ rọrun lati kun. O le ṣee lo bi epo Layer ti nwọle ati epo alalepo ni kikọ aabo omi ati paving opopona.
7. Cationic emulsion bitumen ṣii si ijabọ ni kiakia.
