Kakawanda nokuti pamusoro Mabatirwo Asphalt uye mvura-siyana mazano vaishandisa bhitumini emulsion - Gadziriro imwe mhando umo tudonhwe huru pakuderedza anomirirwa nenzira aqueous chokutambudzika muchimiro yoga zvinhu. To svikiro iri anopiwa ane namira chiito, achishingaira kushandiswa yokuvirisa siyana - emulsifiers. Hazvirambiki kuti bituminous mvura kunobatsira panyaya kuchengetedza zviwanikwa uye zvakatipoteredza rucheno. Kazhinji, vanachiremba mubasa vanotarisana pezvitsiga siyana zvimwe nengoro zvinhu. Saka kuwana Formulations zvingasiyana yekudyidzana kubva mumwe ehupfumi.
Chero bhitumini emulsion zvinoda kuwedzera solvent, uwandu kwayo kunofanira kuva akarurama chaizvo. Zvikasadaro squat kwemunhu zvinoriumba kana kunyanya pokufa musanganiswa anogona kuitika. The solvent rinoshandiswa sezvo kuderedza mumiririri Kuronga mwero viscosity. Panyaya mvura iri rakafanana mvura cationic muvhenganiswa ipapo haanyanyi tainge vhoriyamu pane anionic analogues. Yokupedzisira vavo zvikuru sei chitsama nouipi zviri wakawedzera Urume.
Paaiita wemisanganiswa, chaiyo kugadzwa nokuda kugadzirwa nebhitumini emulsion, iro rine zvakaoma kunzwisisa. Zvinosanganisira: huru chikwata ine colloid chigayo, zvemagetsi kuzvidzora gadziriro, dosing nemvura bhitumini mitsetse, kuchengetwa inokwana siyana zvinhu uyewo nenyere uye pombi. Basa riri kuitwa pachishandiswa kwazvo vaiitawo, murwiyo zvinoratidza mamwe emulsification. The chatingatevedzera chokupedzisira chigadzirwa chiri zvikuru novimba homogeneity pakati musanganiswa uye pretreatment.
Chinenge zviumbu zvese zvinoshandiswa zvakagadzirwa nezvinhu kwete pasi ngura, izvo zvinoita kuti tikwanise kuita kunonyanyisa upenyu basa. Izvi ndezvechokwadi kunyanya vezvikwata uye mitezo iyo zvakananga nehofisi imwe aqueous svikiro. Pari chete kushandiswa zvoga midziyo kuti unhu chigadzirwa, kana bhitumini emulsion rinoita zvose zvinodiwa. The nhamba uye zvechadenga chigadzirwa vari kuyerwa chaiwo sensors. Zvichienderana nokuti ehupfumi yokupedzisira musanganiswa kuvimba emulsifiers aonekwa manufactures mano vanokwanisa yakayamwa zvinoumba nenzira mbiri.
asi bhitumini emulsion iri pamberi kurevawo pemvura, nechigadziko anofanira kunyatsogadzirira. Kubvisa yekare unhani uye siyana nemarara, kuchereka tsitsi millimeters kupfuura vatatu. Uyezve, priming rinoitwa vaine emulsion sezvamunoita. Chidimbu musanganiswa aibuda simba mhando pamusoro kubatwa. Kutarisa kavha inogona kuwanikwa neavhareji kudyiwa chigadzirwa. Kana mvura runopwa kubva mhinduro pamusoro pechiso richaramba nhete firimu nebhitumini, zvinotevera kudzivirira unhani.
