Maitiro ekugadzira anosanganisira: kupisa tembiricha yebhitumene uye sipo mhinduro, kugadzirisa sipo mhinduro pH kukosha, uye kutonga kwekuyerera kwepiipi imwe neimwe panguva yekugadzira.
(1) Kupisa tembiricha yebhitumini uye sipo mhinduro
Bitumen inoda kuve nekupisa kwepamusoro kuti iwane kuyerera kwakanaka. Kunyungudutswa kwe emulsifier mumvura, kuwedzera kwe emulsifier sipo solution kuita, uye kudzikiswa kwemvura-bhitumen interfacial tension zvinoda kuti sipo solution ive pane imwe tembiricha. Panguva imwecheteyo, tembiricha yebhitumeni yakashongedzwa mushure mekugadzirwa haigone kukwira kupfuura 100 ℃, zvikasadaro zvinokonzeresa kufashaira kwemvura. Tichifunga nezvezvinhu izvi, tembiricha yekudziya yebhitumini inosarudzwa kuve 120 ~ 140 ℃, tembiricha yeSipo i55 ~ 75 ℃, uye tembiricha yebhitumini yekubuda nayo haina kukwira kupfuura 85 ℃.
(2) Kugadzirisa sipo mhinduro pH kukosha
Iyo emulsifier pachayo ine imwe acidity uye alkalinity nekuda kwechimiro chayo chemakemikari. Ionic emulsifiers inonyungudika mumvura kugadzira sipo mhinduro. Iyo pH kukosha inokanganisa basa re emulsifier. Kugadzirisa kune yakakodzera pH kukosha kunosimudzira basa remushonga wesipo. Mamwe emulsifiers haagone kunyungudika pasina kugadzirisa iyo pH kukosha kwesipo. Acidity inowedzera basa re cationic emulsifiers, alkalinity inowedzera basa reanionic emulsifiers, uye basa renonionic emulsifiers harina chekuita nehukoshi hwepH. Paunenge uchishandisa emulsifiers, kukosha kwepH kunofanirwa kugadziridzwa zvinoenderana nemirairo yechigadzirwa. Anowanzo shandiswa asidhi nemaalkali ndeaya: hydrochloric acid, nitric acid, formic acid, acetic acid, sodium hydroxide, soda ash, uye girazi remvura.
(3) Kudzora kuyerera kwepombi
Kuyerera kwepaipi yebhitumini nesolution yesipo inotemesa bhitumini yemukati mune emulsified bitumen chigadzirwa. Mushure mekunge emulsification midziyo yagadziriswa, huwandu hwekugadzira hunogadziriswa. Kuyerera kwepombi yega yega kunofanirwa kuverengerwa uye kugadziridzwa zvinoenderana nerudzi rwe emulsified bitumen inogadzirwa. Izvo zvinofanirwa kucherechedzwa kuti huwandu hwekuyerera kwepombi yega yega inofanirwa kuenzana ne emulsified bitumen yekugadzira vhoriyamu.
