1. Yiziphi izinto ezisetshenziselwa amathangi okugcina i-bitumen yerabha
Ithangi lokugcina itiyela lenjoloba liyinhloso ebalulekile ebalulekile ekugandayweni kwemigwaqo. Izinto zokwakha eziningi zinquma impilo yayo yesevisi, izinga kanye nezimo zokusetshenziswa. Ngakho-ke, izinto ezifanele zizokwandisa impilo yesevisi yamathangi okugcina i-bitumen yerabha! Ngakho-ke yiziphi izinto okufanele zisetshenziselwe amathangi okugcina i-bitumen yerabha?
Ukukhiqizwa kwethangi le-asphalt yokugcina i-asphalt kwenziwa endaweni ene-asidi ne-alkaline, ngakho-ke isici sokumelana nokugqwala kwe-asidi kufanele sicatshangelwe ngokugcwele, ikakhulukazi igobolondo kufanele futhi licabangele ukumelana nokubola kwe-asidi. Ngokuvamile, sincoma ukuthi ucabangele insimbi engagqwali. Okwesibili, inqubo yokukhiqiza ithangi lokugcina i-asphalt yenjoloba ngokuyisisekelo yenziwa endaweni engathathi hlangothi. Kufanele sikukhumbuze ngokukhethekile ukuthi ukhonkolo lwe-asphalt luyinqubo ephezulu yokugunda. Kufanele futhi sicabangele amandla we-rotor material. Ngakho-ke, ukuze sikhiqize amathangi okugcina i-asphalt yenjoloba ngokushesha, singakhetha ukuqina kwe-carbon steel ephezulu.

2. Ukubunjwa, izici kanye nokusebenza kwethangi lokugcina i-asphalt yerabha
Ukwakhiwa kwethangi le-asphalt yokugcina irabha: ithangi le-asphalt, ithangi lokuxuba uwoyela elifakwe emulsified, ithangi lesampula lomkhiqizo eliqediwe, iphampu ye-asphalt yesivinini esiguquguqukayo, isivinini esilawula iphampu yokuthambisa, i-homogenizer, iphampu yokuphuma komkhiqizo ophelile, ibhokisi lokulawula likagesi, isihlungi, ipayipi elikhulu lepuleti eliphansi kanye i-valve yesango, njll.
Izici zethangi lokugcina i-asphalt yerabha: ikakhulukazi ukubhekana nenkinga yokuxuba amafutha namanzi. Ithangi lokugcina i-asphalt yenjoloba lisebenzisa izinjini ezimbili zejubane eziguquguqukayo ukushayela iphampu kawoyela wegiya. Ukusebenza kwangempela kunembile futhi kulula. Ngokuvamile, akulula ukungasebenzi kahle. Inempilo ende yesevisi, izici zokusebenza ezizinzile, nekhwalithi ethembekile. Kungumkhiqizo wethangi lokugcina i-asphalt yerabha.
Ngaphambi kokusebenzisa amathangi okugcina i-bitumen yenjoloba, umshini kufanele uhlanzwe ukuze ugweme ukusabela nge-emulsified bitumen ekhiqizwa ngaphambili; ngemva kokuhlanza, i-valve yesisombululo esigcwele i-demulsifier saturated kufanele ivulwe kuqala, futhi ithangi lokugcina itiyela lenjoloba kanye nesisombululo esigcwele umshini wokukhipha umoya kufanele kukhishwe emshinini we-micro-powder ngaphambi kokuba kuvulwe ivalvu yebitumeni; okuqukethwe kwebitumen kukhuphuka kancane kancane kusuka ku-35% kuya phezulu. Uma ithangi lokugcina itiyela lenjoloba lithola ukuthi umshini we-micro-powder awusebenzi kahle noma kukhona ama-flocs etiyela elifafaziwe, ukusetshenziswa kwetiyela kufanele kwehliswe ngokushesha. Ngemva kokukhiqiza ngakunye, amathangi okugcina itiyela enjoloba kufanele avalwe nge-valve yetiyela, bese ivalvu yesisombululo esigcwele i-demulsifier saturated kufanele ivalwe futhi ihlanzwe imizuzwana engaba ngu-30 ukuze kuvinjwe itiyela elifakwe emulsified ukuthi lingahlali esikhaleni futhi libe nomthelela ekusebenziseni okulandelayo.
