Iindidi zezixhobo zebhitumene ezilungisiweyo zinokwahlulwa zibe ziindidi ezininzi. Izixhobo zebhitumene ezilungisiweyo zinokwahlulwa zibe ziindidi ezintathu: uhlobo lokusebenza oluphakathi, uhlobo olusebenzayo olungenasiphelo, kunye nohlobo oluqhubekayo lokusebenza ngokwamanyathelo obugcisa. Kwiindidi ezahlukeneyo zebhitumene elungisiweyo Zeziphi ingqiqo esisiseko malunga nesixhobo?
Izinto ezilungisiweyo zimilise ibhitumene. Ngexesha lemveliso, i-demulsifier, i-asidi, amanzi, kunye nezixhobo ezilungisiweyo ze-latex zixutywa kwitanki yokuxuba isepha, kwaye emva koko i-emulsified bitumen engaphantsi kwamanzi ikhonkrithi ifakwa kwi-colloidal solution mill. Ukusetyenziswa kwetanki zokugcina ibhitumene kufuneka kuthathelwe ingqalelo ukuveliswa okuqhubekayo koomatshini bokuxuba umxube webhitumene, kwaye kuthintelwe utyalo-mali olugqithisileyo, olunokubangela ukusetyenziswa kunye nokunyusa iindleko. Isixa kufuneka simiselwe ngokufanelekileyo ngokusekelwe kusetyenziso lwebhitumene.
Emva kokuba inkonkxa yesepha isetyenzisiwe, isepha iyalungiswa, emva koko kuqaliswe ukuveliswa kwetoti elandelayo. Xa isetyenziselwa ukuvelisa ibhitumene eguqulweyo eguqulweyo, kuxhomekeke kwiteknoloji yezinto ezilungisiweyo, umbhobho we-latex unokudityaniswa ngaphambi okanye emva kwe-micronizer. Usenokungabikho umbhobho welatex ozinikeleyo, kodwa owenziwe ngesandla. Yongeza inani elimiselweyo lelatex kwisitya sesepha.
Isixhobo sebhitumene esilungisiweyo sisixhobo sebhitumene esiguquliweyo esinetanki yokuxuba ulwelo lwesepha, kwaye ulwelo lwesepha lunokutshintshwa emva koko ukuze kuqinisekiswe ukuba ulwelo lwesepha luthi gqolo lugalelwa kwilitye lokusila le-colloidal solution. Itanki yokugcina ibhitumene yolunye uhlobo olutsha lwezixhobo zokugcina ukufudumala kwebhitumene eziphuhliswe ngokudibanisa iimpawu zesiqhelo eziphezulu ze-oyile ezifudumeza i-oyile yokugcina i-bitumen kunye neetanki zokufudumeza ezikhawulezayo zangaphakathi.
Iimpawu zezixhobo zebhitumene ezilungisiweyo zezi: ukufudumeza ngokukhawuleza, ukukhuselwa kwendalo kunye nokonga amandla, imveliso enkulu, akukho kusetyenziswa kwezinto ezisetyenzisiweyo, akukho kuguga, kunye nokusebenza ngokulula. Zonke iinxalenye zinokufakwa kwitanki, zishukunyiswe, ziphakanyiswe, kwaye zihlolwe, nto leyo ilunge ngakumbi. Kulula kakhulu ukuhambahamba. Le mveliso inokufudumeza ibhitumene eshushu ukuya kuma-degrees angama-160 ngaphantsi kwemizuzu engama-30.
