Kwinkqubo yokulungiselela izixhobo ze-bitumen ezilungisiweyo, ukulawula ukushisa kubaluleke kakhulu. Ukuba ubushushu bebhitumene buphantsi kakhulu, ibhitumene iya kuba ngqindilili, ingabi namanzi, kwaye kube nzima ukuyimilisela; ukuba ubushushu be-bitumen buphezulu kakhulu, kwelinye icala, kuya kubangela ukuba i-bitumen iguge. Ngelo xesha, ukushisa kwe-inlet kunye nokuphuma kwe-bitumen e-emulsified kuya kuba phezulu kakhulu, okuya kuchaphazela ukuzinza kwe-emulsifier kunye nomgangatho we-bitumen e-emulsified. Into ekufuneka wonke umntu ayiqonde kukuba ibhitumene yinxalenye ebalulekileyo yebhitumene e-emulsified, ngokuqhelekileyo ibalelwa kwi-50% -65% yomgangatho opheleleyo webhitumene e-emulsified.

Xa ibhitumene etyhidiweyo itshizwa okanye ixutywa, ibhitumene efakwe emulsified iyakhutshwa, yaye emva kokuba amanzi ekuyo ephuphuma, eyona nto iseleyo emhlabeni yibhitumene. Ngoko ke, ukulungiswa kwebhitumene kubaluleke kakhulu. Ukongezelela, wonke umntu kufuneka aqaphele ukuba xa isityalo sebhitumen se-emulsified senziwa, i-viscosity ye-bitumen iyancipha njengoko iqondo lokushisa linyuka. Kuzo zonke i-12 ° C yonyuka, i-viscosity yayo eguqukayo iphantse iphindwe kabini.
Ngexesha lemveliso, ibhitumene yesiseko sokulima kufuneka ifudunyezwe kuqala ibe lulwelo phambi kokuba i-emulsification iqhutywe. Ukuze uziqhelanise nesakhono se-emulsification se-micronizer, i-viscosity eguquguqukayo yebhitumene yesiseko sokulima ilawulwa ngokubanzi malunga ne-200 cst. Iqondo lokushisa eliphantsi, liphezulu i-viscosity, ngoko ke impompo ye-bitumen kufuneka iphuculwe. kunye noxinzelelo lwe-micronizer, ayikwazi ukumiliselwa; kodwa ngakolunye uhlangothi, ukuze ugweme ukuvela komphunga kunye nokunyuka kwamanzi amaninzi kwimveliso egqityiweyo ngexesha lokuveliswa kwebhitumene emulsified, okuya kukhokelela ekugqithiseni, kwaye kunzima ukutshisa ibhitumene yokulima i-substrate ephezulu kakhulu, I-micronizer isetyenziswa ngokubanzi. Ubushushu beemveliso ezigqityiweyo ekungeneni nasekuphumeni kufuneka bube ngaphantsi kwama-85°C.
