Xa isixhobo sesityalo sokuxuba i-asphalt sisebenza, uthuli oluninzi luya kuveliswa kwindawo yokwakha, ngoko ke kuyimfuneko ukuyixhobisa ngezixhobo ezihambelanayo zokususa uthuli. Ngokubanzi, kusetyenziswa umqokeleli wothuli lwengxowa, kwaye ibhegi yokucoca uthuli yinto esebenzayo yokucoca uthuli kunye nokusebenza kakuhle kokungena komoya, ukusebenza kakuhle kokususa uthuli, kunye ne-asidi ethile, i-alkali kunye nokumelana nobushushu.
Emva kwexesha elide lokusetyenziswa, ukuze uqhubeke nomsebenzi wesityalo sokuxuba i-asphalt, isikhwama sokucoca uthuli kufuneka sihlambuluke. Ekubeni ibhegi yokucoca uthuli iyinxalenye ebaluleke kakhulu yomqokeleli wothuli lwengxowa, inokusebenza kakuhle komoya, ukusebenza kakuhle kokususa uthuli, kunye ne-asidi ethile, i-alkali kunye nokumelana nobushushu. Ibrashi enamacala amaninzi isetyenziswa kwinkqubo yokuluka ukunyusa ubukhulu belaphu kwaye yenze i-elastic, ngoko ke isiphumo sokususa uthuli silunge kakhulu, kwaye ubomi benkonzo ngokuqhelekileyo buphindwe kane ukuya kwesithandathu kwelaphu lefayibha yeglasi, ngoko ke ukucocwa kwayo. umsebenzi ubaluleke kakhulu.
Ngoko ke, yintoni imixholo yomsebenzi wokucoca kwingxowa yokucoca uthuli lwesityalo sokuxuba i-asphalt?
Okokuqala, ngenxa yeemeko zangempela ezahlukeneyo, ngaphambi kokucoca, ukuze kuqinisekiswe umphumo wokucoca, kufuneka siqhube iimvavanyo zemichiza kuyo. Amanyathelo aphambili kukukhupha isampula yengxowa, sebenzisa izixhobo zobuchwephesha ukuvavanya ioyile kunye nezinto ezimdaka zengxowa yokucoca, khetha izinto ezifanelekileyo zokuhlamba ngokuhambelana nomxholo wamacandelo, kwaye ucoce ingxowa yokucoca uthuli lwezityalo zokuxuba i-asphalt ubungakanani obukhulu ngaphandle kokubangela nawuphi na umonakalo kuwo.
Okwesibini, ukungcola okulula ukukususa kumphezulu wawo kunokususwa ngokungcangcazela kwe-high-frequency vibration kuqala, ukwenzela ukuba ubumdaka obukhulu kunye nokungcola okungena eludongeni lwengxowa yokucoca kungasuswa kuqala, kwaye akukho mpembelelo ekubanjweni kwefiber. , ukugcina ukusebenza kwesikhwama sokucoca uthuli lwesikhululo sokuxuba i-asphalt kunye ne-peeling elula yokungcola. Emva koko, khetha iiarhente zeekhemikhali ezifanelekileyo ukucwina ibhegi yokucoca, ususe amabala e-oyile kunye nokungcola kwisithuba sengxowa yokucoca, kwaye unyuse ukunyanzeliswa komoya kwengxowa yokucoca ukuya kuthi ga kwinqanaba eliphezulu.
Emva koko, umsebenzi wokucoca uyafuneka. Ngokwale meko ingentla, khetha kuqala izinto ezifanelekileyo zokuhlamba, sebenzisa amanzi aphantsi obushushu bokucoca, gcina iyunifomu yokuhamba kwamanzi, ukuqina okuphakathi, kwaye ungabangeli umonakalo kwisikhwama sokucoca uthuli lwesityalo sokuxuba i-asphalt. Emva koko, umyalelo uyomisa, ukulungiswa kunye nokuvavanya ukuqinisekisa ukuba umgangatho wokucoca uhlangabezana neemfuno.
