Lapho umshini wokuhlanganisa i-asphalt usebenza, uthuli oluningi luvame ukukhiqizwa endaweni yokwakha, ngakho-ke kuyadingeka ukuyihlomisa ngemishini yokususa uthuli ehambisanayo. Ngokuvamile, kusetshenziswa umqoqi wothuli wesikhwama, futhi isikhwama sokuhlunga uthuli siyisihlungi esisebenzayo sothuli esisebenza kahle komoya, ukusebenza kahle kokukhipha uthuli oluphezulu, kanye ne-asidi ethile, i-alkali nokumelana nokushisa.
Ngemuva kwesikhathi eside sokusetshenziswa, ukuze uqhubeke nomsebenzi wesitshalo sokuxuba i-asphalt, isikhwama sokuhlunga uthuli sidinga ukuhlanzwa. Njengoba isikhwama sokuhlunga uthuli siyingxenye ebaluleke kakhulu yomqoqi wothuli wesikhwama, sinomsebenzi omuhle wokungenisa umoya, ukusebenza kahle kokususa uthuli, kanye ne-asidi ethile, i-alkali nokumelana nokushisa. Ukuxubha okunezinhlangothi eziningi kusetshenziswa enqubweni yokuluka ukuze kwandiswe ukushuba kwendwangu futhi kuyenze ibe nokunwebeka, ngakho umphumela wokukhipha uthuli muhle kakhulu, futhi impilo yayo yesevisi ngokuvamile iphindwe kane kuya kweziyisithupha kunendwangu yengilazi yefiber, ngakho ukuhlanzwa kwayo. umsebenzi ubaluleke kakhulu.
Ngakho-ke, yikuphi okuqukethwe komsebenzi wokuhlanza wesikhwama sokuhlunga uthuli sesitshalo sokuxuba i-asphalt?
Okokuqala, ngenxa yezimo ezihlukene zangempela, ngaphambi kokuhlanza, ukuze kuqinisekiswe umphumela wokuhlanza, sidinga ukuqhuba ukuhlolwa kwamakhemikhali kuso. Izinyathelo eziyinhloko ukukhipha isampula yesikhwama, sebenzisa amathuluzi ochwepheshe ukuhlola izingxenye zikawoyela nokungcola kwesikhwama sokuhlunga, ukhethe izinto zokugeza ezifanele ngokuya ngokuqukethwe kwezingxenye, futhi uhlanze isikhwama sokuhlunga uthuli sezitshalo zokuxuba i-asphalt izinga elikhulu ngaphandle kokudala noma yimuphi umonakalo kulo.
Okwesibili, ukungcola okulula ukukususa ebusweni bayo kungasuswa ngokudlidliza kwe-high-frequency kuqala, ukuze ukungcola okukhudlwana nokungcola okungena odongeni lwesikhwama sokuhlunga kususwe kuqala, futhi akukho mphumela ekubanjweni kwe-fiber. , ukugcina ukusebenza kwesikhwama sokuhlunga uthuli lwesiteshi sokuxuba i-asphalt kanye nokuxebuka kalula kokungcola. Bese, khetha ama-agent amakhemikhali afanelekile ukuze ucwilise isikhwama sokuhlunga, ususe amabala kawoyela kanye nokungcola esikhaleni sesikhwama sokuhlunga, futhi ukwandise ukungena komoya kwesikhwama sokuhlunga ngezinga eliphezulu.
Khona-ke, umsebenzi wokuhlanza uyadingeka. Ngokusho kwesimo esingenhla, khetha kuqala izinto ezifanele zokugeza, sebenzisa amanzi aphansi okushisa ukuze uhlanze, gcina umfaniswano wokugeleza kwamanzi, ukuqina okulinganiselwe, futhi ungabangeli umonakalo esikhwameni sokuhlunga uthuli sesitshalo sokuxuba i-asphalt. Khona-ke, i-oda liyamisa, lilungise futhi lihlolwe ukuze kuqinisekiswe ukuthi ikhwalithi yokuhlanza ihlangabezana nezidingo.
