Maitiro ekugadzira emulsified bitumen anogona kukamurwa kuita mana anotevera maitiro: kugadzirira bhitumini, kugadzira sipo, bhitumeni emulsification, uye emulsion kuchengetedza. Tembiricha yakafanira yebhitumeni yekubuda nayo inofanira kunge iri 85°C.

Zvinoenderana nekushandiswa kwebhitumini yakashongedzwa, mushure mekusarudza mhando yakakodzera yebhitumini uye label, iyo bhitumini yekugadzirira nzira inonyanya kupisa bhitumini nekuichengeta pane tembiricha yakakodzera.

1. Kugadzirira kwebhitumini
Bhitumini ndicho chikamu chakakosha chebhitumini yakaitwa emulsified, kazhinji inoverengera 50% -65% yehuremu hwese hwebhitumini.

2.Kugadzirira sipo mhinduro
Zvinoenderana neinodiwa emulsified bhitumini, sarudza yakakodzera emulsifier mhando uye dosage pamwe nemhando yekuwedzera uye dosi, uye gadzira emulsifier aqueous solution (sipo). Zvichienderana ne emulsified bitumen midziyo uye rudzi rwe emulsifier, nzira yekugadzirira yeaqueous solution (sipo) ye emulsifier inosiyanawo.

3. Emulsification yebhitumini
Isa chikamu chinonzwisisika chebhitumini uye sipo yemvura mu emulsifier pamwe chete, uye kuburikidza nemakanika mhedzisiro senge pressurization, kuveura, kugaya, nezvimwewo, bhitumini inoumba yunifomu uye zvidimbu zvidimbu, izvo zvinozoparadzirwa zvakadzika uye zvakaenzana mumvura ine sipo. gadzira homwe dzemvura. Mafuta bitumen emulsion.
Kudzora kwekushisa panguva yekugadzirira bhitumini kwakakosha zvikuru. Kana tembiricha yebhitumini yakanyanya kuderera, ichaita kuti bhitumini ive nepamusoro viscosity, kuoma mukuyerera, uye nekudaro emulsification matambudziko. Kana kupisa kwebhitumini kwakanyanyisa, kunokonzera kukwegura kwebhitumini kune rumwe rutivi, uyewo kuita emulsified bitumen panguva imwe chete. Iyo tembiricha yekubuda nayo yakakwira zvakanyanya, izvo zvinokanganisa kugadzikana kweemulsifier uye kunaka kwebhitumini emulsified.
Tembiricha yemushonga wesipo isati yapinda mumidziyo ye emulsification inowanzodzorwa pakati pe55-75°C. Matangi makuru ekuchengetera anofanirwa kunge akashongedzerwa nemudziyo unonyandura kuti utenderere nguva nenguva. Mamwe ma emulsifiers akasimba patembiricha yemumba anoda kudziyisa nekunyungudutswa asati agadzira sipo. Nokudaro, kugadzirira kwebhitumini kwakakosha.

4. Kuchengeta emulsified bitumen
Iyo emulsified bitumen inobuda mu emulsifier uye inopinda mutangi rekuchengetera mushure mekutonhora. Mamwe emulsifier aqueous solutions anoda kuwedzera asidhi kugadzirisa pH kukosha, asi mamwe (senge quaternary ammonium salts) haadaro.

Kuderedza kuparadzaniswa kwebitumen emulsified. Kana bhitumini yakapfapfaidzwa ikapfapfaidzwa kana kusanganiswa, bhitumini yakavharwa inobviswa, uye mushure mekunge mvura iri mairi yaputika, inosara mumugwagwa ibhitumini. Kuti iite otomatiki inoenderera mberi emulsified bhitumini yekugadzira michina, chimwe nechimwe chikamu chesipo (mvura, asidhi, emulsifier, nezvimwewo) inopedzwa otomatiki nechirongwa chakaiswa nemidziyo yekugadzira pachayo, chero bedzi kupihwa kwechimwe chinhu kuchivimbiswa; yesemi- Inoenderera kana inopindirana yekugadzira michina inoda kugadzirira sipo yemanyorero zvinoenderana neformula inodiwa.
