Izitshalo zebitumen ezilungisiwe emulsified zibhekana kanjani nokuqiniswa kwetiyela ebusika?
Ngokwenqubo yokukhiqiza, izitshalo zebitumen eziguquliwe zingahlukaniswa zibe izinhlobo ezintathu: ukusebenza kwemishini yebitumen eshintshiwe ngezikhathi ezithile, ukusebenza kwemishini yebitumen eshintshiwe kancane kancane, kanye nokusebenza kwemishini yetiyela eshintshiwe eqhubekayo. Ngesikhathi sokukhiqizwa kwezinto eziguquliwe zebitumen emulsified, i-demulsifier, i-asidi, amanzi, nezinto eziguquliwe ze-latex zixutshwa ethangini lokuxuba insipho, bese ziphonswa emshinini wokugaywa we-colloid ngetiyela. Ngemva kokuba ithangi lensipho seliphelile, ligcwaliswa ngensipho, bese kuqedwa ukukhiqizwa kwethangi elilandelayo.
Isitshalo sebitumen esilungisiwe esifakwe emulsified okukhulunywe ngaso lapha sihlanganisa iphampu yamanzi ashisayo nepompo ejikelezayo. Lolu hlobo lwephampu yamanzi eyi-centrifugal ngokuvamile lusebenzisa iphampu yephayiphi eyi-centrifugal. Kunendawo yokukhipha indle ezansi kwephampu yephayiphi i-centrifugal. Qaphela ukuthi yindawo yokukhipha indle ngaphansi kwephampu ye-bitumen eshintshiwe emulsified. Amanzi ethangini lamanzi akhishwa ngevalvu yokuhlunga. Ezinye izisetshenziswa zebitumen ezilungisiwe ze-emulsified azinayo i-valve yokuhlunga yokonga izindleko zemishini, ngakho-ke ingathululwa kuphela ngokukhulula amabhawodi ehange e-flange ngezansi. Kunezinhlobo ezimbili eziyisisekelo zamaphampu etiyela afakwe emulsified emakethe, amaphampu egiya noma amaphampu amaphakathi. Amaphampu agiya angakhipha kuphela uketshezi olusepompo nge-flange exhumayo yepayipi. Amaphampu e-Centrifugal aphatha indle ngokusebenzisa indle yawo.
Lapho isetshenziswa ekukhiqizeni okokusebenza kwebitumen emulsified, ngokobuchwepheshe obuhlukahlukene bokuguqulwa, ipayipi le-latex lingaxhunywa ngaphambi kwesigayo se-colloid noma ngemva kwesigayo se-colloid, noma lingekho ipayipi le-latex, kodwa inani elidingekayo le-latex lengezwa ngesandla ithangi lensipho.
Imishini yebitumen e-emulsified ngokuvamile isebenzisa iphansi lekhoni. Kodwa-ke, ukuze kucutshungulwe kangcono i-coefficient ye-bitumen e-emulsified, i-inlet ne-outlet ngokuvamile akubekwa phansi. I-emulsion ethambisayo (ikakhulukazi amanzi) izohlala phansi ethangini, futhi le ngxenye yoketshezi olusele idinga ukukhishwa nge-valve yokuhlunga ezansi. Kokubili izinto ezishisayo nezibandayo kumshini wokushisa we-bitumen efakwe emulsic kudingeka zikhishwe.
Kuzoba khona i-emulsion esele noma amanzi esigayweni se-colloid. Igebe phakathi kwe-stator ne-rotor yesigayo se-colloid lingaphakathi kwe-1mm. Uma kukhona amanzi amancane ayizinsalela ezintweni zebitumen elungisiwe emulsified, kuzodala ingozi yezitshalo zebitumen ezilungisiwe ze-frostbite. Izinsalela emshinini wokugaywa we-colloid zingelashwa ngokuxegisa amabhawodi oxhumano lwamapayipi omkhiqizo oqediwe. Umzimba we-valve wemishini eminingi yebitumen eshintshiwe emulsified wamukela uhlobo lwe-pneumatic, futhi kuzoba nengxenye yepompo. Amanzi asemoyeni azoba amanzi agcinwe ethangini ngemva kokunwetshwa. Le ngxenye yamanzi kufanele ikhishwe ebusika.
Lapho ukhipha amanzi noma ipayipi le-emulsion elimanzisa lesitshalo sebitumen esishintshiwe se-emulsified, i-valve yebhola kufanele ibe sendaweni evulekile. Uma kukhona amanzi empahleni yebhitumene eshintshiwe emulsified ngesikhathi sokusebenza noma iphampu yevacuum ibangelwa ukuvalwa kwevalvu, uketshezi olukupompo nepayipi alukhishwa, okuzodala ingozi yebitumen eshintshiwe ye-frostbite eshintshiwe. Amanzi ajikelezayo okupholisa emshinini we-colloid, izigayo eziningi ze-colloid zisebenzisa izimpawu zemishini, ezosebenzisa amanzi ajikelezayo okupholisa. Le ngxenye yamanzi ajikelezayo okupholisa kufanele ikhishwe. Ezinye izindawo lapho amanzi angaba khona. Ipayipi likawoyela odlulisa izinga lokushisa eliphezulu leplanti yebitumen elungisiwe akulula ukujiya ebusika futhi ayidingi ukuthululwa. Izitshalo zebitumen ezilungisiwe ze-emulsified zizojiya ebusika, kodwa ivolumu akulula ukukhuphuka ngesikhathi senqubo ye-condensation futhi ayidingi ukuthululwa.
