Mhedzisiro yekudzora tembiricha pane yakagadziridzwa bhitumeni midziyo
Muchigadziro chekugadzirisa bhitumeni midziyo, kutonga kwekushisa kunokosha zvikuru. Kana tembiricha yebhitumini yakadzikira, bhitumini ichava gobvu, isinganyanyi kuyerera, uye yakaoma kuisa emulsify; kana tembiricha yebhitumini yakanyanyisa, kune rumwe rutivi, ichaita kuti bhitumu ichembera. Panguva imwecheteyo, kutonhora kwemukati uye kubuda kwebhitumen yakasvibiswa kuchave kwakanyanyisa, izvo zvichakanganisa kugadzikana kwemushonga uye kunaka kwebhitumen yakasvibiswa. Zvinofanirwa kunzwisiswa nemunhu wese ndezvekuti bhitumini chinhu chakakosha chebhitumini yakashongedzwa, kazhinji inoverengera 50% -65% yehuwandu hwese hwemhando yebhitumini yakashongedzwa.
Kana iyo emulsified bitumen ikapfapfaidzwa kana kusanganiswa, bhitumini yakagadziriswa inobviswa, uye mushure mekunge mvura iri mairi yaputika, inosara pasi ibhitumini. Nokudaro, kugadzirira kwebhitumini kunonyanya kukosha. Mukuwedzera, munhu wose anofanirawo kuziva kuti kana emulsified bitumen plant inogadzirwa, viscosity yebhitumini inoderera sezvo tembiricha inowedzera. Pamusoro pekuwedzera kwe12 ° C, viscosity yayo ine simba inenge yakapetwa kaviri.
Panguva yekugadzira, bhitumini yekurima inofanira kutanga yapiswa kuti iite mvura isati yaitwa emulsification. Kuti uenderane nekugona emulsification kweiyo micronizer, iyo ine simba viscosity yekurima base bhitumeni inowanzodzorwa kuita 200 cst. Iyo yakaderera tembiricha, iyo yakakwirira viscosity, saka bhitumene pombi inoda kuvandudzwa. uye kudzvanywa kweiyo micronizer, haigone kuve emulsified; asi kune rumwe rutivi, kuitira kuti udzivise evaporation uye evaporation yemvura yakawandisa mune yakapedzwa chigadzirwa panguva yekugadzirwa emulsified bitumen , izvo zvinozoita kuti demulsification, uye zvakare zvakaoma kupisa kurimwa substrate bhitumen yakakwirira kwazvo, iyo micronizer inonyanya kushandiswa. Tembiricha yezvigadzirwa zvakapedzwa pamusuwo nekubuda inofanira kunge yakaderera pane 85°C.
